• What parameters should be considered when ordering solar wall lights with human body sensors

  Jan 23, 2026

  When ordering solar wall lights with human body sensors (outdoor use as the main scenario), the selection of parameters must be centered on core demands: stable solar power supply, accurate human body induction, reliable outdoor durability, and matching lighting needs (e.g., courtyard, corridor, wall, gate). The parameters are divided into 6 core categories (solar power supply, human body induction, lighting performance, structural durability, functional adaptability, installation/after-sales), and each parameter is clearly explained for its selection criteria and applicable scenarios—this is directly applicable to procurement list formulation, product customization, and supplier communication (suitable for foreign trade procurement, project matching, and retail product selection).       All parameters are based on the outdoor solar wall light (the most common application), and the selection principle is: no over-pursuit of high parameters, only matching the actual use scenario (e.g., low-brightness warm white is sufficient for a small courtyard, and high-brightness cold white with a long induction distance is needed for a gate/wall).   Core Parameters to Consider When Ordering Solar Wall Lights with Human Body Sensors   1. Solar Power Supply Parameters (Foundation of Stable Operation)   Solar power supply is the core of solar wall lights—poor parameter matching will lead to insufficient charging, short battery life, and failure to work on rainy days (the most important selling point of solar lights for users). All parameters are adapted to the outdoor wall light’s small size and low power characteristics (no need for high-power configuration like solar street lights).   Solar Panel: Material & Power Material (priority): Monocrystalline silicon (conversion efficiency ~22%-25%, high charging efficiency in weak light/overcast days, small size, perfect for wall lights with limited installation space); polycrystalline silicon is not recommended (low efficiency, large size). Power: 2W-10W (mainstream for solar wall lights). Selection criteria: Match the light’s total power (e.g., 3W LED full brightness → 2W-3W solar panel; 8W LED full brightness → 5W-8W solar panel).   Battery: Type & Capacity Type (mandatory): Lithium iron phosphate (LiFePO4) battery (outdoor special, high temperature resistance, overcharge/over-discharge resistance, service life 3-5 years) > Lithium polymer (Li-poly) battery; lead-acid battery is strictly not recommended (large size, short life, easy to leak). Capacity: 1200mAh-8000mAh (3.7V is the mainstream voltage). Core indicator: Full charge continuous working capacity (rainy day endurance)—at least support 3-5 rainy days of normal induction work (supplier must provide test data). Key protection: Must have overcharge, over-discharge, short circuit, and over-temperature protection (avoids battery damage and fire risk in outdoor high temperature).   Charging & Discharging Performance Charging time: 6-8 hours of direct sunlight to full charge (standard for outdoor solar products). Light control charging: Auto-charge in daytime (sensor dormant) + auto-activate induction/lighting at night (must be a standard function, no manual switch required).         2. Human Body Sensor Core Parameters (Core Function, Accurate & Anti-Misoperation)   The human body sensor is the core functional part—poor parameters will lead to misoperation (triggered by heat sources/animals) or missed operation (no induction for people passing by). PIR (Passive Infrared) sensor is the mainstream for solar wall lights (cost-effective, low power consumption); microwave radar sensor is an optional upgrade (suitable for harsh environments).   Basic Induction Parameters (PIR is the mainstream, mandatory for all models)   Induction Detection Range & Angle Detection distance: 3m-10m (mainstream for wall lights); selection by scenario: Courtyard/corridor → 3-5m; gate/wall → 6-10m (installation height is 2-3m, the standard height for wall lights, and the supplier must mark the detection range at the standard height). Detection angle: 120°-180° (wide-angle induction, fits wall light’s one-sided installation, no blind area for pedestrian/vehicle passing).   Induction Trigger Mode (standard for high-quality products) Constant dim light + human body induction full bright (the only recommended mode): Dim light (10%-30% rated power) for basic safety illumination at night; full bright when human/vehicle is detected (avoids sudden darkness and improves user experience). Pure induction (no light when no induction) is not recommended (poor safety, easy to trip).   Induction Delay Time 30s-5min (adjustable is preferred); mainstream default: 60s-120s. Avoid too short (frequent on/off) or too long (wasting power) delay time.   Anti-Misoperation Design (mandatory) Dual-element PIR probe (only responds to moving infrared heat sources (human/vehicle), no trigger for static heat sources (e.g., air conditioners, street lamps, stationary pets)); Anti-glare/anti-rain interference (the sensor probe has a protective cover, no misoperation by rainwater/sunlight direct shot).         Optional Induction Upgrade: Microwave Radar Sensor   If used in harsh scenarios (e.g., rainy/foggy areas, dense foliage, metal wall installation), choose microwave radar sensor instead of PIR (higher cost, better performance):   Advantages: Penetrates thin obstacles (fog/leaves), no misoperation by temperature, and can detect both moving humans and vehicles; Disadvantages: Slightly higher power consumption (must match a larger capacity battery).   3. Lighting Performance Parameters (Match Actual Illumination Needs)   Solar wall lights are for auxiliary outdoor lighting (not main lighting), so the lighting parameters focus on practicality (no over-pursuit of ultra-high brightness). The core is to distinguish dim light/full bright dual brightness (matching induction mode) and color temperature (matching scene atmosphere).   Light Source Type (mandatory) SMD LED patch (SMD2835/5730 is the mainstream): High brightness, low power consumption, long service life (>50,000 hours), uniform light emission (fits wall light’s flat light-emitting design); COB LED is optional (higher brightness, concentrated light, suitable for gate lighting). Reject incandescent/energy-saving lamps (high power consumption, short life, not suitable for solar power supply).   Brightness (Lumen, lm) & Dual Power Mode Brightness unit: Lumen (lm) (the only accurate indicator, reject "wattage" for brightness comparison). Mainstream specification: Dim light: 20-100lm | Full bright: 100-800lm (solar wall light’s optimal range). Small courtyard/balcony: 100-300lm (full bright); Gate/wall/corridor: 300-800lm (full bright).   Must mark dim light/full bright separate lumen values (supplier’s common trick: only mark full bright brightness, hiding low dim light brightness).   Color Temperature Warm white (3000K-3500K): Soft light, warm atmosphere—suitable for courtyard/balcony/porch (the most popular for residential use); Neutral white (4000K-4500K): Natural light, high visibility—suitable for corridor/alley; Cool white (6000K-6500K): Bright light, clear illumination—suitable for gate/wall/parking space (needs long-distance induction lighting). Avoid mixed color temperature (uneven light, poor experience).   Light Emitting Angle 60°-120° (mainstream for wall lights); wide angle (90°-120°) for large-area illumination (courtyard/wall); narrow angle (60°-90°) for long-distance illumination (gate).     4. Structural & Durability Parameters (Outdoor Use Core: Waterproof, Anti-Corrosion, Anti-Aging)   Solar wall lights are used outdoors for a long time, so durability directly determines the service life—the key parameters are IP protection grade, material, and temperature adaptability (must be strictly required for suppliers, avoid "fake outdoor" products).   IP Protection Grade (mandatory, no compromise) At least IP65 (dust-tight, water jet proof)—the minimum standard for outdoor solar wall lights (resists rain, snow, dust, and splashing water from all directions); IP66/IP67 is preferred (waterproof and dustproof, can withstand heavy rain/immersion for a short time)—suitable for rainy areas, coastal areas, or wall lights installed in low-lying places. Reject IP rating below IP65 (e.g., IP44, only splash-proof, not suitable for outdoor long-term use).   Lamp Body & Bracket Material Main body: ABS engineering plastic (reinforced anti-aging) (light weight, anti-corrosion, low cost—mainstream for ordinary solar wall lights) or aluminum alloy (anodized) (high strength, anti-corrosion, heat dissipation—suitable for high-end models/gate lighting); Bracket: Stainless steel/galvanized iron (anti-rust, firm load-bearing—avoids bracket breakage after long-term outdoor use); Key requirement: Anti-UV/anti-aging treatment (the lamp body surface has a UV coating, no yellowing/cracking after 2-3 years of sunlight).   Working Temperature Range -20℃ ~ +60℃ (mainstream for outdoor solar products)—adapts to most regions’ climate (cold winter, hot summer); For extreme climate (northeast China/Europe and America cold areas), choose -30℃ ~ +60℃ (low temperature resistant battery is required).   Solar Panel Protection The solar panel has a tempered glass cover (scratch-resistant, high light transmittance) or PET laminating (anti-aging, water-proof)—avoids panel damage by falling leaves/stones/rain.     5. Functional Adaptability Parameters (Improve Use Experience, Optional but Practical)   These are value-added functions (no mandatory requirement, but can improve product competitiveness). Choose according to procurement budget and user needs—focus on energy saving and practicality (avoid useless fancy functions).   Dimmable/Adjustable Induction Parameters Preferred: Adjustable delay time/induction sensitivity/dim light power (via a small switch on the lamp body)—adapts to different user scenarios (e.g., shorten delay time for energy saving, increase sensitivity for weak light areas).   Timing Function Optional: Segmented timing (e.g., auto-reduce dim light power after 23:00, or auto-enter sleep mode)—saves battery power, suitable for areas with low night traffic.   Emergency Constant Bright Mode Optional: Manual constant full bright (via a switch)—used for emergency lighting (e.g., power outage, outdoor activities), a small selling point for residential use.   Light Control + Induction + Time Control Three-in-One High-end model: Integrate light control (auto on/off), human body induction (brightness switch), and time control (energy saving)—the most intelligent configuration, suitable for high-budget procurement.   Battery Reminder Function Optional: Low battery indicator (LED flash)—reminds users of abnormal charging (e.g., solar panel blocked by leaves), avoids product failure misjudgment.         6. Installation & After-Sales Parameters (Procurement Practicality, Avoid Follow-Up Troubles)   These parameters are often ignored but directly affect installation efficiency and after-sales maintenance—must be clearly agreed with the supplier in the order (avoid missing parts, no after-sales).   Installation Method Wall-mounted (the only main mode for solar wall lights); two options: Drilling installation (firm, suitable for concrete/brick walls—supplier must provide complete accessories: expansion tube, stainless steel screws, screwdriver); No-drill adhesive installation (convenient, no wall damage—suitable for tile/glass walls, with high-strength 3M adhesive (temperature resistant, waterproof) provided by the supplier).   The bracket must be angle-adjustable (30°-90°)—adjust the solar panel’s angle to face the sun (maximize charging efficiency).   Accessory Completeness Mandatory accessories: Installation screws, expansion tubes, user manual (multilingual manual is required for foreign trade procurement: English/Spanish/French, etc.); Optional accessories: No-drill adhesive, solar panel extension cord (for wall lights installed in shaded areas, extend the solar panel to a sunny place—cord length 1-3m).   Warranty Period & After-Sales Minimum warranty period: 1 year (whole machine); core parts (battery/solar panel/LED): 2 years (the battery is the most vulnerable part, must have a longer warranty); Clarify after-sales terms: Free replacement for non-human damage within the warranty period, supplier bears the shipping cost (or agreed upon according to the order quantity); Require the supplier to provide product test report (IP waterproof test, solar charging test, induction performance test)—for foreign trade export (e.g., EU/US market, need CE/FCC/RoHS certification).     Key Procurement Tips (Match Parameters to Scenarios, Avoid Over-Procurement)   Residential small courtyard/balcony/porch: PIR induction (3-5m) + IP65 + warm white 3000K + 100-300lm (full bright) + no-drill installation—focus on atmosphere and convenience. Residential gate/wall/parking space: PIR induction (6-10m) + IP66/IP67 + cool white 6000K + 300-800lm (full bright) + drilling installation—focus on illumination and induction distance. Corridor/alley/community public area: PIR induction (5-8m) + IP65 + neutral white 4000K + 200-500lm (full bright) + three-in-one control—focus on practicality and energy saving. Coastal/rainy/cold areas: Aluminum alloy lamp body + IP67 + lithium iron phosphate battery (-30℃) + monocrystalline silicon solar panel—focus on anti-corrosion, waterproof and low temperature resistance.   Standard Procurement Parameter List (Directly Editable for Supplier Communication)     Parameter Category Core Parameters Selection Standard/ Mainstream Specification   Solar Power Supply Solar panel Monocrystalline silicon, 2W-10W     Battery LiFePO4, 3.7V, 1200mAh-8000mAh, 3-5 rainy days endurance     Protection Overcharge/over-discharge/short circuit/over-temperature   Human Body Induction Induction type/range/angle PIR (mainstream), 3-10m, 120°-180°     Trigger mode/delay time Constant dim light + full bright, 30s-5min (adjustable)     Anti-misoperation Dual-element probe, anti-rain/anti-glare   Lighting Performance Light source/brightness SMD2835/5730, Dim:20-100lm Full:100-800lm   Color temperature/light angle 3000K-3500K (warm white), 60°-120°   Structural Durability IP rating/material ≥IP65, ABS reinforced plastic/ aluminum alloy     Working temperature -20℃ ~ +60℃ (extreme climate: -30℃ ~ +60℃)   Functional Adaptability Adjustable parameters Delay time/induction sensitivity/dim power   Installation & After-sales Installation/accessories Wall-mounted (drill/no-drill), complete screws/expansion tube     Warranty/certification Whole machine 1y, core parts 2y; CE/FCC/RoHS (for export)

• Working principle of solar street lights using PIR sensors

  Jan 23, 2026

  PIR (Passive Infrared) sensors are a core energy-saving component for solar street lights, designed for low-traffic areas (sidewalks, rural lanes, park trails). They work by detecting the infrared radiation emitted by human/animal bodies (no active radiation output, hence "passive") and collaborating with the solar street light’s core control system (light control, charge-discharge controller) to achieve the classic "dim light standby, full bright when motion detected, delayed dim after motion" mode.       This design maximizes battery energy utilization (saving 60%–80% power compared to constant bright mode) and prolongs the service life of batteries and LED lamps—the PIR sensor never works alone, it is fully integrated with light control (photoresistor) and the solar charge-discharge controller (the "brain" of the light), and all power is supplied by the solar battery (charged by the solar panel during the day).   Core Components of the PIR Solar Street Light System   The PIR function relies on the synergy of 5 key parts, with the PIR sensor module consisting of a dual-element infrared probe + Fresnel lens (the core of motion detection):   Solar panel: Converts sunlight into electricity to charge the lithium battery (LiFePO4 is the mainstream for solar street lights). Lithium battery: Stores electrical energy for night lighting. PIR sensor module: Dual-element probe + Fresnel lens + signal amplification circuit (detects human/animal motion). Solar charge-discharge controller: Integrates light control, PIR signal processing, power switching, and battery protection (the core of system coordination). LED light source: Realizes power switching (dim light/full bright).   Step-by-Step Working Principle   The entire working process is divided into Daytime Charging & PIR Dormancy and Night Lighting & PIR Motion Detection, with light control as the fundamental trigger switch (to avoid PIR misoperation during the day).   Phase 1: Daytime – Solar Charging + PIR Sensor Dormancy   When the ambient illuminance (sunlight) is higher than the preset light control threshold (50–100 lux, adjustable), the photoresistor in the controller sends a "daytime" signal to the main control chip. The controller cuts off the power supply to the LED light and PIR sensor module, putting the PIR sensor into deep dormancy (no power consumption, no motion detection) to avoid misoperation by sunlight, birds, or falling leaves. The solar panel converts sunlight into DC power, and the controller performs constant current/constant voltage charging for the lithium battery (with overcharge, overvoltage, and short-circuit protection) to store energy for night use.     Phase 2: Night – Light Control Trigger + PIR Standby (Dim Light Mode)   When the ambient illuminance drops to the night light control threshold (5–15 lux, adjustable, e.g., after sunset), the photoresistor sends a "nighttime" signal to the controller. The controller immediately activates the PIR sensor module (puts it into low-power standby detection) and supplies a small current to the LED light, making it enter dim light standby mode (10%–30% of the rated power, e.g., 10W for a 100W street light). This dim light provides basic safety illumination and ensures the PIR sensor is ready for detection. At this stage, the PIR sensor module is in low-power detection state (power consumption <1mA): the Fresnel lens focuses the ambient infrared radiation on the dual-element infrared probe, and the probe continuously collects the static infrared radiation of the surrounding environment (e.g., walls, trees, roads) as the "baseline signal".   Phase 3: Motion Detection – PIR Trigger + LED Full Bright   This is the core working step of the PIR sensor, relying on the infrared temperature difference and motion change between the human/animal body and the environment:   When a person/animal (with a body temperature of ~37℃ for humans) moves into the PIR detection range (5–15m, adjustable) and angle (120°–180°, adjustable), the Fresnel lens focuses their body infrared radiation (λ=8–14μm, the most sensitive band for PIR sensors) onto the dual-element probe. The dual-element probe detects a sudden change in infrared radiation intensity (the temperature of the human body is much higher than the ambient environment, forming a clear infrared temperature difference) and a spatial displacement signal (caused by movement). The probe converts this physical change into a weak electrical signal (μV level). The signal amplification circuit in the PIR module amplifies the weak electrical signal and sends a "motion detected" trigger signal to the solar charge-discharge controller. The controller immediately switches the LED power supply circuit, increasing the current to the rated full power (e.g., 100W) – the street light instantly turns to full bright for high-brightness illumination.       Phase 4: Motion Disappears – Delayed Full Bright + Restore Dim Light   To avoid frequent on/off of the street light (caused by short-term motion) and improve user experience, the PIR system has a customizable delay function:   When the person/animal moves out of the PIR detection range, the probe no longer detects infrared temperature difference and motion changes, and the trigger signal is cut off. The controller does not switch back to dim light immediately, but maintains LED full bright for a preset delay time (30s–5min, factory adjustable or on-site settable via the controller). After the delay time ends, the controller cuts the LED power supply current and restores the dim light standby mode, and the PIR sensor returns to low-power detection to wait for the next motion trigger.   Phase 5: Dawn – Light Control Shutdown + PIR Dormancy   When the ambient illuminance rises above the daytime light control threshold at dawn, the controller repeats Phase 1: cuts off power to the LED and PIR sensor, the PIR enters deep dormancy, and the solar panel resumes charging the battery—completing a full working cycle.   Key Design Features of PIR Sensors in Solar Street Lights (Anti-Misoperation & Customization)   Dual-element probe anti-misoperation: The dual-element design only responds to changing infrared signals (motion). Static heat sources (e.g., street lamps, hot water pipes, stationary animals) will not trigger the sensor, avoiding false full bright. Fresnel lens for wide detection: The lens focuses scattered infrared radiation onto the probe, expanding the detection range (5–15m) and angle (120°–180°), and ensures the sensor can detect motion even at an installation height of 3–6m (standard for solar street lights). All parameters adjustable: Detection range, detection angle, delay time, and dim light/full bright power ratio can all be set via the solar controller to adapt to different scenarios (e.g., shorten delay time in remote rural areas, expand detection range in community sidewalks). Time control superposition (optional): Mid-to-high-end models can superimpose time control with PIR: e.g., after 2 AM (lowest traffic), the dim light power is further reduced (5% of rated power) or the delay time is shortened (30s) to save more energy for the battery.   Core Advantages of This Design for Solar Street Lights   Maximize energy saving: Avoids constant full bright, significantly reduces battery power consumption, and ensures the street light can work continuously for 3–7 rainy days (a key selling point of solar street lights). Extend component life: Lower average working power reduces the heat generation of LED lamps and the discharge depth of lithium batteries, prolonging their service life. Low maintenance: PIR sensor modules have no moving parts, low power consumption, and high stability (service life >5 years), matching the overall service life of solar street lights. Cost-effective: PIR sensors are low-cost and easy to integrate into the solar controller, with no additional wiring required—suitable for mass application in low-traffic areas.       Typical Application Scenarios     PIR solar street lights are the first choice for areas with uneven and low pedestrian/vehicle flow, such as rural village roads, community footpaths, park trails, factory peripheral roads, sidewalks, and mountain roads. For high-traffic areas (municipal main roads, commercial blocks), PIR is usually replaced with microwave (radar) sensors (wider detection, anti-interference, suitable for vehicles and pedestrians).

• What are the common time control methods for solar street lights?

  Jan 21, 2026

  Solar street light time control methods are core to balancing illumination demand, energy saving and battery lifespan, and are often integrated with light sensing, induction and smart communication for practical use. Below are the mainstream, market-proven time control methods (sorted by popularity and application scope), with their working principles, advantages, disadvantages and applicable scenarios—tailored for solar street light product technical specifications, marketing copy and project solutions.   All methods are based on the solar charge-discharge controller (the "brain" of the light), and most support segmented power adjustment (e.g., full power for a set time, then half power) as an energy-saving auxiliary function, which is the standard configuration for modern solar street lights.     1. Light + Time Combined Control (Most Popular & Universal)   Working Principle   The most widely used method for solar street lights (accounting for over 80% of general scenarios). It triggers lighting via light sensing and controls the working duration/power via time setting:   Light control trigger: Automatically turns on when the ambient illuminance drops to a preset threshold (5–15 lux, adjustable) and turns off when the illuminance rises above the threshold at dawn; Time control regulation: After the light is turned on by light sensing, it operates according to the preset time program (e.g., full power for 4 hours → half power for 4 hours, or fixed time off like "turn off at 2 AM").   Advantages   Low cost, easy operation, no manual trigger, adapts to seasonal changes of day/night length, and balances basic illumination and energy saving.   Disadvantages Susceptible to interference from ambient artificial light (e.g., billboard lights, building neon lights); the illuminance threshold needs on-site debugging.   Applicable Scenarios Urban secondary roads, residential community roads, rural highways, park paths (all general solar street light application scenarios—the first choice for standard products).   2. Longitude & Latitude Smart Timing Control (High Precision for Municipal Projects)   Working Principle An upgraded intelligent time control method based on geographic location: the controller has a built-in longitude and latitude algorithm; after inputting the installation location’s longitude and latitude, it automatically calculates the local sunrise/sunset time, and dynamically updates the on/off time with seasonal changes (no manual adjustment for spring/summer/autumn/winter). It can be superimposed with segmented power time control (full/half power) and light control for double insurance.   Advantages Ultra-high timing precision, no seasonal debugging required, anti-ambient light interference, and one-time setting for permanent use.   Disadvantages Slightly higher controller cost than basic light-time control; requires accurate input of the installation site’s longitude and latitude.   Applicable Scenarios Municipal main roads, high-specification industrial parks, cross-latitude engineering projects, large-scale scenic area roads (key government projects with high requirements for automation and precision).     3. Sensor + Time Control (Energy-Saving Type for Low Traffic Flow)   A high-efficiency energy-saving solution combining human/vehicle induction with time control, often used with light control (the most cost-effective energy-saving method for solar street lights). The two mainstream induction technologies are microwave (radar) induction (recommended, anti-interference) and human infrared induction (for pedestrian-only areas).   Working Principle Light control triggers the light to turn on in low-power constant brightness mode (20%–30% of rated power); when the sensor detects a human/vehicle passing by, it automatically boosts to full power for illumination; after the induction ends, it delays for a preset time (30s–5min, adjustable) and restores low power. It can be superimposed with time control: e.g., turn off the induction function after 00:00 and keep low power, or turn off the light directly at a fixed time.   Advantages Maximizes energy saving (energy saving rate up to 60%–80%), prolongs battery and LED lamp life, and balances basic security illumination (low power) and high-brightness demand (induction full power).   Disadvantages Higher cost than basic light-time control; the induction distance/angle needs on-site debugging.   Applicable Scenarios Sidewalks, residential footpaths, country lanes, park trails, industrial park secondary roads (areas with uneven pedestrian/vehicle flow and high energy-saving requirements).   4. Manual Fixed Timing Control (Basic & Backup Type) The most traditional time control method, the foundation of all other control modes (now mostly used as a backup function for other intelligent control methods).   Working Principle   Set the fixed on/off time and power segment directly through the physical buttons or digital display of the solar controller (e.g., turn on at 18:00, full power for 3 hours, half power for 3 hours, turn off at 00:00). No automatic adjustment for external factors (light, season, human/vehicle).   Advantages Simple operation, lowest controller cost, suitable for areas with completely fixed lighting schedules.   Disadvantages Requires manual re-adjustment for seasonal changes of day/night length; high maintenance cost for large-scale projects; cannot adapt to actual illumination demand.   Applicable Scenarios   Remote rural villages with fixed living schedules, small temporary construction sites, simple courtyard solar street lights (low-budget, small-scale simple scenarios), or as a backup for intelligent control failure.       5. Smart Remote Time Control (IoT Type for Smart City) The high-end time control method for smart city projects, integrating IoT communication technology with all the above time control/induction/light control functions.   Working Principle The solar street light controller is equipped with GPRS/4G/LoRa/WiFi communication modules and connects to a cloud management platform. The on/off time, power segmentation, induction parameters, and light control threshold can be set and adjusted in real time via computer/mobile phone APP/wechat mini program; it supports batch management of hundreds/thousands of street lights, and real-time monitoring of battery power, lamp working status and fault alarm.   Advantages Remote batch operation, no on-site debugging required; flexible and real-time adjustment of lighting schedules according to actual demand; intelligent fault monitoring reduces maintenance cost; supports personalized timing strategies (e.g., different time control for weekends/weekdays).   Disadvantages Highest overall cost (controller + communication module + cloud platform); dependent on network signal (unavailable in remote areas without 4G/LoRa coverage).   Applicable Scenarios Smart city municipal roads, large industrial parks, airport peripheral roads, scenic areas with unified management, commercial block roads (large-scale, high-specification intelligent lighting projects).   🌟 Key Supplementary: Segmented Power Time Control (Universal Auxiliary Function)   All the above time control methods can be superimposed with segmented power timing—the core energy-saving design of solar street lights (a must-mention technical point in product marketing). It means the light automatically adjusts the illumination power in different time periods after turning on (e.g., 18:00–22:00 full power [100W] for peak traffic, 22:00–06:00 half power [50W] for low traffic), which effectively saves solar panel and battery energy without affecting basic illumination.   📊 Market Application Summary   Control Method Cost Level Applicable Scenario Market Popularity Light + Time Combined Medium General roads (most scenarios) ★★★★★ Longitude & Latitude Timing Medium-High Municipal high-spec projects ★★★★☆ Sensor + Time Control Medium Low traffic flow energy-saving areas ★★★★☆ Manual Fixed Timing Low Simple small-scale/backup ★★☆☆☆ Smart Remote Time Control High Smart city/large-scale IoT projects ★★★☆☆       The mainstream configuration of commercial solar street light products in the market is Light + Time Combined Control (main) + Manual Timing (backup), and the mid-to-high end models are upgraded to Longitude & Latitude Timing + Microwave Induction + Segmented Power for higher competitiveness.

• Which types of streetlights are more suitable for rural roads/courtyards, urban main roads/squares, and remote areas without electricity?

  Jan 18, 2026

  The suitability of streetlight types varies significantly depending on the application scenarios, such as rural roads/courtyards, urban main roads/squares, and remote off-grid areas.    For rural roads and courtyards   Recommended types: Small-to-medium power solar-powered LED streetlights and low-voltage LED courtyard lights   These streetlights are ideal for rural settings for several reasons. Solar-powered LED models require no complex wiring, which saves construction costs and adapts to the relatively scattered layout of rural roads and courtyards. Their moderate brightness (typically 10–30W for courtyards and 30–60W for rural roads) is sufficient to ensure safe nighttime travel and daily lighting needs without causing light pollution. Low-voltage LED courtyard lights, on the other hand, are safe to install and operate, making them perfect for residential courtyard areas where safety is a priority. Both types feature low energy consumption and minimal maintenance requirements, aligning with the operational needs of rural areas with limited maintenance resources.     For urban main roads and squares   Recommended types: High-power high-lumen LED streetlights and smart integrated LED streetlights   Urban main roads have high traffic volumes and require bright, uniform, and stable lighting, while squares need wide-area illumination with good color rendering. High-power LED streetlights (80–200W for main roads, 150–300W for large squares) deliver high luminous efficiency, excellent color rendering index (CRI ≥ 80), and long service life (up to 50,000 hours), reducing long-term replacement and maintenance costs for urban management departments.   Smart integrated LED streetlights take it a step further, with functions like dimming control, motion sensing, and remote monitoring. They can automatically adjust brightness based on traffic flow (e.g., reducing brightness during off-peak hours) to save energy, making them a cost-effective and eco-friendly choice for modern urban infrastructure.     For remote areas without electricity access   Recommended types: Off-grid high-efficiency solar-powered LED streetlights and wind-solar hybrid streetlights   These areas lack a stable power grid, so streetlights must operate independently. Off-grid solar LED streetlights are equipped with high-efficiency photovoltaic panels and large-capacity lithium batteries, which store solar energy during the day for nighttime use. They are suitable for remote regions with abundant sunlight, such as mountainous pastoral areas and border posts.   For areas with insufficient sunlight but ample wind resources, wind-solar hybrid streetlights are a better option. They combine wind turbines and solar panels to generate and store electricity, ensuring stable power supply even in harsh weather conditions. Both types are fully self-sufficient, require no grid connection, and have low long-term operational costs, making them the optimal lighting solution for off-grid remote areas.

• Which intelligent monitoring solution (such as remote dimming and fault warning) is suitable for integrated versus split solar street lights?

  Jan 16, 2026

  Intelligent Monitoring Solution Adaptability: Integrated vs. Split Solar Street Lights   The suitability of intelligent monitoring solutions (e.g., remote dimming, fault warning) for integrated and split solar street lights is mainly determined by their structural characteristics, installation scenarios, and maintenance requirements. Below is a targeted analysis of the matching schemes for both types:   1. Suitable Intelligent Monitoring Solutions for Integrated Solar Street Lights   Integrated solar street lights feature a highly integrated design, with solar panels, LEDs, lithium batteries, and controllers all housed in a single enclosure. This structure imposes requirements of simplicity, miniaturization, and low power consumption on monitoring systems.   1.1 Remote Dimming Solution   Recommended Scheme: Wireless single-node dimming system based on LoRa/NB-IoT communication Adaptability Analysis: Integrated street lights have no external wiring, so wireless communication avoids the trouble of additional cable laying. The load power of a single integrated street light is relatively limited (usually within 300W). The single-node dimming mode can independently adjust the brightness of each lamp (e.g., switching between 100% brightness at peak hours and 30% energy-saving brightness at off-peak hours) without relying on a complex centralized control platform. The built-in controller of integrated street lights can be pre-embedded with dimming control modules during production, realizing plug-and-play without post-installation modification.         1.2 Fault Warning Solution   Recommended Scheme: Integrated sensor + cloud platform fault self-reporting system Adaptability Analysis: Embedded voltage and current sensors inside the lamp body can monitor the operating status of the battery, LED driver, and solar charging module in real time. When anomalies such as battery over-discharge, LED burnout, or charging failure occur, the system automatically sends alarm information to the cloud platform via wireless signals. Given the integrated structure, it is impossible to monitor components separately. The solution focuses on overall fault diagnosis (e.g., identifying abnormal charging efficiency of the whole machine, lamp body short circuit) rather than single-component fault location, which matches the maintenance logic of integrated street lights (usually replacing the whole machine directly when a fault occurs). Suitable for scenarios with a large number of decentralized installations (e.g., rural roads, courtyards), where managers can receive alarm messages remotely without on-site inspections.     2. Suitable Intelligent Monitoring Solutions for Split Solar Street Lights   Split solar street lights separate solar panels, batteries, lamp heads, and controllers into independent modules, with distributed installation. Their monitoring systems require modularity, strong expandability, and multi-component independent monitoring capabilities.   2.1 Remote Dimming Solution   Recommended Scheme: Centralized wireless control system based on GPRS/4G communication Adaptability Analysis: Split street lights are often used in high-power scenarios (e.g., urban main roads, squares, with single-lamp power above 300W). Centralized control can realize unified dimming of regional street lights (e.g., adjusting the brightness of all street lights in a certain road section synchronously according to traffic flow). The independent controller of split street lights can be connected to multiple load modules, supporting flexible dimming strategies (e.g., stepwise dimming, human radar induction linkage dimming). It can also link with traffic monitoring data to adjust brightness in real time (increasing brightness during peak traffic hours and reducing brightness during low-traffic periods). For large-scale projects, the centralized control platform can realize group management of street lights, which is more efficient than single-node control of integrated street lights.         2.2 Fault Warning Solution   Recommended Scheme: Distributed multi-node monitoring system with component-level fault positioning Adaptability Analysis: Split street lights allow independent deployment of monitoring sensors for each module: solar panel power generation sensors, battery temperature and voltage sensors, lamp head current sensors, etc. This enables component-level fault positioning (e.g., distinguishing whether the charging failure is caused by a damaged solar panel or a faulty controller; identifying whether the lamp does not light up due to LED driver damage or battery depletion). The monitoring system can be connected to the cloud platform through a centralized gateway, realizing unified data collection and alarm management. Maintenance personnel can directly carry targeted spare parts for on-site repairs according to the alarm information, avoiding the high cost of overall replacement (a key advantage of split street lights in later maintenance). Suitable for large-scale municipal projects, where precise fault positioning can significantly reduce maintenance costs and shorten troubleshooting time.         3. Comparative Summary of Monitoring Solutions for Two Types of Street Lights   Monitoring Function Integrated Solar Street Lights Split Solar Street Lights Remote Dimming Wireless single-node dimming; simple operation; suitable for decentralized small-power scenarios Centralized group dimming; flexible strategy; suitable for large-scale high-power scenarios Fault Warning Integrated overall fault self-reporting; fast alarm; maintenance relies on overall replacement Distributed component-level fault positioning; precise troubleshooting; supports targeted maintenance Communication Mode Priority to LoRa/NB-IoT (low power consumption, long transmission distance) Priority to GPRS/4G (large data volume, strong real-time performance) Cost Control Low initial deployment cost; no additional wiring required Slightly higher initial cost; but lower long-term maintenance cost for lar

• How Do All-in-One Solar Street Lights Work on Cloudy or Rainy Days?

  Jan 07, 2026

  All-in-one solar street lights—like LEADRAY’s high-performance models—are engineered with intelligent energy management systems and robust core components to ensure reliable operation even in low-light (cloudy) or no-sunlight (rainy) conditions.   Their functionality hinges on three key principles: efficient energy capture, reliable energy storage, and smart power regulation.     1. First: The Basic Working Principle (Foundation for Bad Weather Performance)   Before diving into cloudy/rainy days, let’s recap the core workflow of all-in-one solar street lights—this explains why they can “survive” without direct sunlight:   Charging Phase: During the day, solar panels convert sunlight into electrical energy, which is stored in the built-in battery via an intelligent controller. Discharging Phase: At dusk, the light sensor triggers the lamp to turn on, using the stored energy to power the LED chips. Key Adaptation: Even on cloudy/rainy days, the system prioritizes “energy conservation” while maintaining basic lighting needs—thanks to upgraded components and smart logic.   2. How They Handle Cloudy Days (Low-Light Charging + Stable Discharging) Cloudy days don’t mean zero sunlight—they just mean sunlight is scattered (not direct). LEADRAY’s all-in-one solar street lights overcome this with two critical upgrades:   a. High-Efficiency Solar Panels: Capture Scattered Light Effectively LEADRAY uses enhanced monocrystalline silicon solar panels (conversion efficiency ≥23%), which outperform standard panels in low-light conditions. Unlike traditional panels that rely on direct sunlight, monocrystalline cells can absorb scattered light (e.g., light filtered through clouds, reflected light from the ground/atmosphere). Even on heavily overcast days, the panels generate 30-50% of the energy they produce in direct sunlight—enough to replenish the battery for nightly use.       b. Intelligent MPPT Controller: Maximize Charging Efficiency The built-in Maximum Power Point Tracking (MPPT) controller dynamically adjusts the charging voltage and current to match the panel’s output. On cloudy days, when light intensity fluctuates, the MPPT controller instantly optimizes the charging process—ensuring every watt of scattered light is converted into stored energy (vs. 10-15% energy loss with basic PWM controllers).   c. Stable Discharging: No Compromise on Lighting Quality As long as the battery is sufficiently charged (from sunny days or partial cloudy-day charging), the lamp maintains its full brightness (e.g., 80W/100W/120W output) throughout the night. For prolonged cloudy spells (3-5 days), the system can switch to “energy-saving mode” (if equipped with a motion sensor): it dims to 30-50% brightness when no movement is detected, then boosts to full brightness when motion is sensed—extending runtime while meeting safety lighting needs.     3. How They Survive Rainy Days (Reliable Energy Storage + Weatherproof Design) Rainy days often mean little to no solar charging—so the lamp’s performance depends entirely on battery capacity and system durability:   a. High-Capacity LiFePO4 Battery: Backup Power for 2-3 Rainy Days LEADRAY equips its all-in-one solar street lights with LiFePO4 (Lithium Iron Phosphate) batteries, which offer superior energy density and cycle life compared to traditional lead-acid batteries. A fully charged LiFePO4 battery (e.g., 12V 100Ah for 100W lamps) can power the light for 8-12 hours per night for 2-3 consecutive rainy days. For areas with frequent rain, optional high-capacity batteries (e.g., 12V 150Ah) extend backup time to 4-5 days. LiFePO4 batteries also perform stably in humid environments (a key advantage over lead-acid batteries, which are prone to leakage or performance degradation in moisture).   b. IP65 Waterproof & Dustproof Design: Protect Core Components All-in-one solar street lights integrate panels, battery, controller, and LEDs into a single sealed housing. LEADRAY’s models feature an IP65 waterproof rating and corrosion-resistant aluminum alloy casing—preventing rainwater, dust, or humidity from damaging internal components (e.g., short-circuiting the battery or controller) during heavy rain.   c. Low-Power LED Chips: Minimize Energy Consumption The LED chips used in LEADRAY’s lamps have a high luminous efficacy (100-130lm/W), meaning they produce more light with less energy. For example, a 100W LED lamp consumes only 100Wh per hour—far less than traditional sodium lamps (which consume 250-400Wh per hour). This low power draw ensures the battery’s stored energy lasts longer on rainy days.       4. LEADRAY’s Extra Advantages for Bad Weather Performance To further enhance reliability in cloudy/rainy conditions, LEADRAY adds two exclusive upgrades:   Anti-reflective Coating on Panels: Reduces light reflection and improves absorption of scattered light—boosting cloudy-day charging efficiency by an additional 10-15%. Temperature Adaptability: The battery and controller are designed to work in extreme temperatures (-20℃ to 60℃), ensuring stable performance even in cold, rainy climates (where battery capacity often drops for inferior products).   Final Summary   All-in-one solar street lights don’t “stop working” on cloudy or rainy days—they adapt through:   ✅ Scattered light capture (high-efficiency panels + MPPT control) for cloudy-day charging;   ✅ Long-term energy storage (high-capacity LiFePO4 batteries) for rainy-day backup;   ✅ Smart energy conservation (motion sensors + low-power LEDs) to extend runtime;   ✅ Durable weatherproof design to protect components from rain and humidity.   LEADRAY’s all-in-one solar street lights take these advantages further—ensuring consistent, reliable lighting for roads, parks, rural areas, and remote locations, regardless of the weather. Choose LEADRAY for a lighting solution that works every day, come rain or shine.
