Solar Street Light Factory's Patented Technology: Driven by Innovation, Leading Industry Quality Improvements

In the solar street light industry, patents are not only a badge of honor for technological innovation, but also a strong guarantee of product performance and quality.

Thanks to years of dedicated research and development, our factory has secured numerous patents focused on the three key areas of solar street light development: core components, intelligent control, and durable design.

These patents address industry pain points and provide customers with more efficient, intelligent, and durable solar street light products.

 "High-Efficiency Concentrating Solar Panel Structure" Patent [Patent No.: ZL 2018-2-1089398.1]

Traditional solar panels are limited by their angle of illumination and area, making it difficult to achieve higher power generation efficiency.

Our patented "dual-axis automatic tracking bracket + Fresnel concentrating lens" design enables solar panels to automatically track the sun's position 24 hours a day.

Combined with the concentrating lens, this increases light intensity by 30%, boosting photovoltaic conversion efficiency from the industry average of 20% to over 23%.

Under the same sunlight conditions, power generation increases by 15%-20%, effectively shortening streetlight charging times and improving battery life in rainy weather.

"Adaptive Temperature Compensation Lithium Battery Management System" Patent [Patent No.: ZL 2019-2-0085607.3]

Lithium battery performance is significantly affected by temperature, with capacity degradation at low temperatures and lifespan shortened at high temperatures.

Our developed BMS system, with a built-in high-precision temperature sensor, monitors the battery pack's temperature in real time and automatically adjusts the charging voltage and current.

At low temperatures, the charging voltage is increased to activate battery activity; at high temperatures, the charging current is reduced to prevent overheating.

Testing has shown that this system can maintain over 85% of the lithium battery's capacity at temperatures as low as -20°C, extending the cycle life by 20% (from 1,500 to 1,800 cycles), making it suitable for complex climates such as those in cold and tropical regions.

Patent for "High Color Rendering, Low Luminous Decay LED Light Source Module"[Patent No.: ZL 2017 2 1093420.X]

The lighting effect must not only be "bright" but also "true to color reproduction." Our LED light source modules utilize a special phosphor formula with a color rendering index (Ra) exceeding 90 (compared to 70-80 for conventional LEDs).

This makes objects appear more vivid and realistic under the light, enhancing road lighting safety. Furthermore, our optimized chip heat dissipation structure reduces thermal resistance by 20%, effectively suppressing light decay.

After 5,000 hours, light decay is less than 3% (compared to the industry average of 5%), ensuring long-term, stable illumination for the streetlights.

Intelligent Control Innovation Patent: Making Streetlights "Thinking" and More Energy-Efficient

"Multi-Mode Intelligent Dimming and Remote Monitoring System" Patent [Patent No.: ZL 2016 2 1088792.3]

Traditional streetlights are often operated in a constant-on mode, wasting energy.

Our intelligent dimming system integrates four modes: light control, time control, motion detection, and remote control. It automatically turns off during the day and turns on automatically in the evening based on ambient light.

It automatically reduces brightness late at night when traffic is scarce (e.g., full brightness for the first four hours, half brightness for the last four hours), saving 30%-40% energy.

It instantly increases brightness when pedestrians or vehicles approach, ensuring safety. Through a mobile app or computer, you can remotely monitor the real-time status, power consumption, and fault information of each streetlight, automatically reporting any faults and significantly reducing operation and maintenance costs.

Patent for the "Smart Predictive Maintenance System for Solar Streetlights Based on Big Data Analysis" [Patent No.: ZL 2020-2-029817.X]

Preventive maintenance is key to ensuring the long-term stable operation of streetlights. This system collects information such as power generation data, power consumption data, fault records, and environmental parameters from streetlights.

Using big data algorithms, it predicts component aging and failure risks (e.g., the remaining life of lithium batteries and the decline in solar panel power generation).

Based on these predictions, maintenance personnel can plan maintenance plans in advance, preventing sudden streetlight failures and reducing the failure rate by over 60%, ensuring continuous lighting.

Patented Durable Design: Adapts to complex outdoor environments and extends streetlight lifespan

Patented "Wind-Resistant and Corrosion-Resistant Integrated Pole Structure" [Patent No.: ZL 2019 3 0487328.0]

Outdoor streetlights face the rigors of strong winds, heavy rain, and salt spray corrosion. Our poles utilize a "high-strength Q345 steel + hot-dip galvanizing + fluorocarbon spraying" process. The zinc layer is over 80μm thick, and the fluorocarbon coating offers 15 years of weather resistance, effectively resisting salt spray and acid rain corrosion.

Furthermore, our optimized pole cross-sectional shape and mechanical structure have been wind tunnel tested to withstand winds exceeding force 12, ensuring the streetlights' stability in harsh environments such as coastal areas and plateaus.

Patented "Quick Installation and Convenient Maintenance Structure" [Patent No.: ZL 2021 3 0024903.8]

Traditional streetlight installation and maintenance procedures are cumbersome and time-consuming. Our designed "quick-install lamp pole connection structure" uses a "flange + high-strength bolt" connection.

No complex welding is required during installation, and two people can complete the lamp pole assembly in 15 minutes, which is 50% more efficient than traditional methods.

Lamps, controllers and other components adopt a "modular design" that can be quickly disassembled and replaced.

A single maintenance person can complete common fault repairs, significantly reducing maintenance time and costs.

Patent Application Results and Customer Value

These patented technologies have been fully implemented in our solar street light products, delivering significant results:

Performance Improvement: Average battery life has increased from 3-5 days on rainy days to 5-7 days, brightness uniformity has improved by 25%, and the effective illumination range has expanded by 15%;

Quality Reliability: Over the past three years, the product failure rate has decreased by 50%, the lighting rate in municipal projects has consistently remained above 98%, and the product lifespan has been extended from 5-8 years to 8-10 years;
