Description

Product Introduction

◎Power efficiency breakthrough: The 500W high-power design achieves a luminous flux of 72,000 lumens, covering an area of 180㎡, with an energy efficiency ratio increased by 20%. Combined with the intelligent gradient power supply mode, it meets the lighting needs of main roads and significantly improves energy utilization.

◎Multi-modal environmental perception: Integrating a high-precision temperature and humidity sensor (±0.2℃/±1.5%RH) and a millimeter-wave radar (15-meter detection distance), it realizes real-time monitoring of environmental data, disaster early warning, and accurate identification of human behaviors, with a false trigger rate of <0.1%.

◎Full-scenario adaptability: Through IP65 protection, salt spray testing, and a modular quick-detach structure, it is suitable for extreme climates and complex terrains. It supports independent replacement of solar panels, batteries, and sensors, improving maintenance efficiency by 87.5%.

Core Value of High-Power Design

1.Qualitative Leap in Coverage and Illuminance

The 500W high-power design integrates 144 high-luminous-efficiency LED lamp beads (single-bead lumen value ≥150lm) with a professional lens array, achieving a luminous flux of over 72,000 lumens and an illuminance uniformity of more than 0.7. Taking road lighting as an example, at an installation height of 8 meters, it can cover an area of 180 square meters with a stable illuminance of 30-50lux, fully meeting the main road lighting requirements specified in the Code for Design of Urban Road Lighting (CJJ45-2015).

Comparison of measured data

Parameter	300W Traditional Street Light	500W Intelligent Street Light	Improvement Range
Luminous Flux (lm)	36,000	72,000	100%
Coverage Area (㎡)	90	180	100%
Energy Efficiency Ratio (lm/W)	120	144	20%

2.Revolutionary Upgrade of Energy System

High-power output requires a more robust energy storage system. This product adopts a ternary lithium-ion battery pack (capacity ≥48V 200Ah) combined with monocrystalline silicon solar panels (conversion efficiency ≥23%), achieving a daily power generation of 8.5kWh (under 5 hours of sunlight). Through MPPT (Maximum Power Point Tracking) technology, energy utilization is 30% higher than that of traditional PWM controllers. Even in rainy weather (with an average of 3 hours of sunlight per day), it can still ensure 7 consecutive days of full-power operation.

◎Gradient power supply mode: Automatically switches power (full power/50%/20%) according to ambient light intensity, and automatically reduces frequency to energy-saving mode during unmanned hours at night;

◎Battery health management system: Real-time monitoring of battery internal resistance and temperature, dynamically adjusting charging and discharging curves to extend battery life to more than 8 years;

◎Emergency energy reserve: 20% of the electricity is reserved for emergency lighting in extreme weather, ensuring continuous lighting in key areas.

Multi-Modal Environmental Perception System

1.High-Precision Temperature and Humidity Composite Sensor

Integrated with the Swiss Sensirion SHT41 digital sensor, it achieves ±0.2℃ temperature accuracy and ±1.5%RH humidity accuracy, with a sampling frequency of 1 time per second. Real-time analysis of environmental data through the edge computing module triggers linked control strategies:

◎Temperature regulation: When the ambient temperature exceeds 40℃, the cooling fan is automatically activated and the LED driving current is reduced to prevent light decay;

◎Humidity warning: When humidity exceeds 85%RH for 2 consecutive hours, the built-in dehumidification device in the lamp pole is triggered to avoid short circuits of electrical components;

◎Disaster response: A sudden temperature drop (ΔT＞10℃/h) combined with sudden humidity changes links with the municipal system to issue freezing warnings.

2.Millimeter-Wave Radar + Infrared Dual-Mode Human Sensing

Breaking through the 3-5 meter sensing distance limit of traditional PIR sensors, a 24GHz millimeter-wave radar module (detection distance 15 meters, angle 120°) is adopted, combined with a pyroelectric infrared sensor to achieve:

◎Accurate human recognition: Double verification through Doppler effect and thermal radiation characteristics, with a false trigger rate of <0.1%;

◎Behavioral pattern analysis: Distinguishes the movement trajectories of pedestrians, vehicles, and animals, and dynamically adjusts lighting strategies (e.g., increasing illuminance to 80lux when vehicles pass by).
