The time control function of integrated solar street lights is a core part of their intelligent operation, designed to optimize energy use, extend battery life, and match lighting needs to specific time periods.
It works by pre-setting or dynamically adjusting lighting brightness and duration based on time, ensuring efficient energy storage (daytime) and rational energy consumption (nighttime).
Below is a detailed breakdown of its working principles, common modes, adjustment methods, and advantages:
Time control is one of the lighting modes that used in the integrated solar street light, it can also be used in the integrated solar garden light and integrated solar billboard light.
We set up the data in the controller base on the requirement from customers or according to the practical application, after the integrated solar street light was installed and operated, it will work automatically according to the data we set up.
1.Core Principle of Time Control
Integrated solar street lights integrate a smart controller (usually MPPT or advanced PWM) that connects to the solar panel, battery, and LED light source. The time control function relies on the controller’s built-in clock chip and pre-programmed logic to:
Detect time: Track 24-hour cycles (some controllers support GPS or network synchronization for higher accuracy).
Link to brightness: Adjust the LED’s power output (e.g., 100% brightness, 50% dimming) according to pre-set time segments.
Coordinate with battery status: If the battery’s remaining capacity is too low (e.g., <20%), the controller may automatically reduce brightness to avoid over-discharging, prioritizing basic lighting needs.
For example:
The default of ourLeadray Integrated solar street lightis “1227”. “1227” means we set up the light to be lit in 1 hour at 30% light on+2 hours at100% light on+ 2 hours at 50% light on+7 hours at 20%.
That is to say the integrated solar street light start working from 6pm, and from 6pm to 7pm the street light has only 30% light on; then from 7pm to 9pm, the light will be full brightness(100% light on); From 9pm to 11pm, 50% light on;
From 11am to 6am(the next day) 20% light on. The integrated street light will shift from one setting to another automatically(including on and off), we take this way (1hour+2hours+2hours+7hours) as a default because we think this meets the people's movement.
How to Set/Adjust Time Control
The adjustment method depends on the controller’s design, but most integrated solar street lights offer two user-friendly options:
Option 1: On-Site Manual Adjustment (Basic Models)
The light’s controller has a built-in button panel (usually hidden under a waterproof cover) or a small LCD screen.
Users press specific buttons to set:
Total nighttime duration (e.g., 10 hours, 12 hours).
Brightness for each time segment (e.g., Segment 1: 100%, Segment 2: 50%).
Motion sensor delay (if applicable, e.g., 30 seconds).
Example: For SZ Leadray LRC-H series, pressing the "SET" button cycles through time segments, and the "+/-" buttons adjust brightness.
Option 2: Remote Control/APP Adjustment (Advanced Models)
High-end integrated solar street lights (e.g., for large municipal projects) support remote management via Bluetooth, WiFi, or LoRa:
Users connect to the controller via a dedicated APP (e.g., Leadray’s smart lighting management platform) or a remote control.
Adjustments can be made wirelessly (within 10–50 meters for Bluetooth, or kilometers for LoRa) to:
Modify time segments and brightness.
Check real-time battery status (to avoid over-discharging).
Reset settings or enable/disable motion sensors.
Advantage: Saves time for large-scale projects (e.g., adjusting 100 lights in a park without on-site visits).
4. Key Advantages of Time Control for Integrated Solar Street Lights
Extends Battery Life: By avoiding unnecessary high-brightness operation, time control reduces battery discharge depth, prolonging the battery’s service life (e.g., from 5 years to 8–10 years for LiFePO₄ batteries).
Ensures Stable Lighting: Prevents the light from turning off prematurely due to insufficient battery (e.g., low brightness at night ensures the battery lasts until dawn).
Matches Actual Needs: Customizable segments adapt to different user scenarios (e.g., 100% brightness for busy roads, low brightness for quiet paths).
Reduces Maintenance: Unlike traditional grid-powered street lights, there’s no need for manual on/off or seasonal timer adjustments (for smart models).
