◎ Advantages of high-power technology: Adopting 200W-300W high-power LED modules, through batwing light distribution, triple heat dissipation and intelligent dimming technology, the illuminance per unit energy consumption is increased by 120%. It is suitable for wide roads and industrial scenarios, with lower total life cycle costs.

◎ Green environmental protection system: From mercury-free lithium iron phosphate batteries, POE packaging to recyclable aluminum alloy lamp bodies, the entire chain is non-toxic. It reduces carbon emissions by 18.7 tons in a 25-year life cycle and supports a circular economy model.

Microcomputer Controller

The Powerful Solar Street Lights are equipped with a 32-bit ARM Cortex-M4 intelligent controller, which integrates four-dimensional environmental sensing and three-level energy management, supports IoT remote monitoring, and achieves the optimal balance between lighting efficiency and energy utilization.

Four-Dimensional Environmental Sensing System

◎Photosensitive Sensor: Adopts ROHM high-precision photodiode with a response wavelength range of 300-1100nm, which can accurately identify changes in morning and evening light and automatically switch working modes.

◎Microwave Radar: Integrates a 24GHz frequency band radar module with a detection distance of 15m and an angle of 120°. When pedestrians or vehicles are detected, the illuminance is increased from 30lux to 150lux within 3 seconds.

◎Temperature Compensation: Built-in NTC thermistor to monitor battery temperature in real time (-20℃ to +65℃), dynamically adjust charging current to prevent low-temperature overcharging or high-temperature over-discharging.

◎Rain and Fog Detection: Through a capacitive humidity sensor, when the ambient humidity is >85%, the lighting time is automatically extended by 30 minutes to improve visibility in rainy and foggy weather.

Three-Level Energy Management Strategy

◎Maximum Power Point Tracking (MPPT): Uses the perturb and observe algorithm to capture the maximum power point of the solar panel within 0.1 seconds, which is 25% more efficient than traditional PWM controllers.

◎Battery Health Management: Predicts the remaining battery capacity (SOC) based on the Kalman filter algorithm. When SOC < 20%, it automatically switches to energy-saving mode, extending battery life by 30%.

◎Load Dynamic Allocation: Intelligently adjusts the LED driving current according to the remaining power and time parameters. For example, in rainy days with SOC = 50%, it prioritizes ensuring full-power lighting in the first half of the night and reduces to 50% brightness in the second half of the night.

Internet of Things (IoT) Integration Capability

Supports LoRaWAN/NB-IoT dual-mode communication, allowing remote parameter setting (such as lighting duration, induction sensitivity) through the cloud platform, and real-time monitoring of device status (voltage, current, illuminance).

It has a fault self-diagnosis function. When battery undervoltage, LED open circuit, or sensor failure occurs, the problem can be quickly located through LED flashing codes (such as 3 long and 2 short flashes), improving maintenance efficiency by 60%.

High-Power Street Lights

◎Optical Design Innovation

Adopts batwing light distribution lens, which evenly distributes light on both sides of the road through aspheric refraction and total reflection principles. The road surface uniformity (Uo) reaches 0.72, far exceeding the national standard requirement of 0.4.

The color rendering index (Ra) is >80, and the color temperature is 5000K±200K, which is close to natural light, reducing driver visual fatigue and lowering the accident rate by 18%.

 

◎Heat Dissipation System Revolution

Integrates a triple heat dissipation structure of microchannel cold plate + heat pipe + graphene coating. Laboratory tests show that at an ambient temperature of 25℃, after 8 hours of continuous operation, the LED junction temperature is stable below 68℃, and the light decay rate is only 3% per year.

Compared with low-power street lights, high-power modules have a larger heat dissipation area, reducing the temperature rise per watt by 42% and extending the service life to 100,000 hours (L70 standard).

 

◎Intelligent Dimming Compatibility

Supports 0-10V/PWM dual-mode dimming, which can be linked with the microcomputer controller to dynamically adjust power according to traffic flow and time period (e.g., reducing to 30% brightness from 2-5 a.m.).

Reserves a DALI interface, which can be connected to the smart lighting management system to realize single-lamp control or group control, with an energy-saving rate of 75%.
