80w Solar Street Light

Product Introduction

◎Advantages of 80W low-power design: Achieving 160lm/W luminous efficiency through monocrystalline silicon + gallium nitride LED chips, the power is halved while the brightness is doubled. The total cost over 10 years is 59% lower than that of 200W sodium lamps, with remarkable effects in carbon emission reduction and light pollution control.

◎Triple-function sensor: Integrating humidity, temperature, and infrared sensors, it supports dynamic dimming (20% brightness when no one is present), fire/water immersion early warning, and extreme weather response. The false alarm rate is 80% lower than that of ordinary infrared sensors.

◎Scenario-based value verification: In rural areas of Yunnan, it achieves 7-day battery life on cloudy and rainy days, saving 21.9 million kWh of electricity annually; in Suzhou Industrial Park, through security linkage, theft cases have decreased by 90% and fire response time has been shortened to 2 minutes.

Low-Power Design

1.Energy-Saving Logic of 80W Power

◎Monocrystalline silicon PERC cells: With a photoelectric conversion efficiency of 22.8% (industry average 18%), combined with a 600Wh lithium iron phosphate battery (DOD 80% cycle life ≥6000 times), ensuring continuous lighting for 12 hours under 80W power;

◎Gallium nitride (GaN) LED chips: Adopting Flip-chip packaging technology, thermal resistance is reduced by 40%, and luminous efficiency is increased to 160lm/W (industry mainstream 120lm/W). An 80W power can output 12,800lm effective luminous flux;

◎Microprism lens array: Through a 120° batwing light distribution design, light is accurately projected onto the road surface (no upward scattering), improving light utilization rate by 65% compared to traditional sodium lamps, with actual lighting effect equivalent to a 200W sodium lamp.

2.Environmental Friendliness of Low Power

◎Carbon emission reduction: A single street lamp reduces carbon dioxide emissions by 1.2 tons per year (calculated by thermal power generation). The 10-year emission reduction of 100 street lamps is equivalent to planting 120,000 trees;

◎Light pollution control: Complies with IDA (International Dark-Sky Association) standards, with road surface illuminance uniformity ≥0.7 (sodium lamps only 0.4), avoiding the glare problem of "bright under the lamp, dark between lamps";

◎Material recyclability: The lamp body uses 95% recyclable aluminum alloy, and the battery recycling rate exceeds 90%, certified by the EU WEEE Directive.

Triple-Function Environmental Sensor

1.Sensor Technical Parameters and Integrated Design

This product innovatively integrates a high-precision humidity sensor (±2%RH), industrial-grade temperature sensor (-40℃~+85℃), and PIR infrared human body sensor (detection distance 12 meters) into the lamp head, achieving performance optimization through the following designs:

◎Anti-interference structure: The sensor module adopts a metal shield and a waterproof and breathable membrane. The humidity sensor passes the IP67 protection level test, and the temperature sensor error is ≤0.5℃ within the range of -20℃~+60℃;

◎Low-power design: The infrared sensor is usually in a dormant state (power consumption <0.1W), wakes up the main lamp when detecting human movement, and the humidity/temperature sensor collects data every 10 minutes and uploads it to the cloud;

◎Wireless communication: Built-in LoRa module (transmission distance 1.5km), supporting connection with smart city platforms, real-time monitoring of environmental data and triggering linkage strategies.

2.Sensor Function Comparison and Scenario-Based Verification

(1) Infrared-Induced Dynamic Dimming

Traditional solar street lamps mostly adopt light control + time control mode, maintaining full power operation at night regardless of whether someone passes by. This product realizes three-level dimming through PIR infrared sensors:

◎Unoccupied state: The light brightness remains at 20% (16W), with illuminance ≥5lx (meeting basic safety needs);

◎Someone approaching (within 5 meters): Brightness increases to 60% (48W), with illuminance ≥15lx (avoiding glare from sudden brightening);

◎Someone staying (for more than 3 seconds): Brightness rises to 100% (80W), with illuminance ≥30lx (meeting activity needs).

(2) Humidity-Temperature Linked Security

Through the collaborative work of humidity and temperature sensors, this product can achieve the following security functions:

◎Early fire warning: When the temperature sensor detects a continuous 10-minute temperature rise rate >3℃/min and humidity <40%RH, it automatically triggers an audible and visual alarm (volume ≥100dB) and pushes alarm information to the administrator's mobile phone;

◎Water immersion detection: In underground garages or low-lying road sections, when the humidity sensor detects humidity >90%RH for 5 consecutive minutes, it automatically switches the light to a red flashing mode (frequency 2Hz) to prompt vehicles to detour;

◎Extreme weather response: When the temperature is < -10℃, the battery preheating function is automatically activated (power consumption <5W) to prevent low temperature from reducing charge and discharge efficiency.
