Description

Product Introduction

◎Multi-sensor fusion technology: The Automatic LED Street Light integrates four major sensors (microwave radar, infrared, photosensitive, temperature and humidity), realizing full-dimensional perception of "light-human-vehicle-environment" and dynamic dimming, saving 62%-78% energy compared with traditional solutions.

◎Advantages of IP65 protection rating: Compared with IP54, IP65 has significantly improved capabilities in dustproofing (fully sealed), waterproofing (immersion in 1-meter deep water for 30 minutes), and resistance to extreme environments (salt spray/high-pressure water gun/temperature cycle), with the sealing life extended by 5 times.

◎Energy efficiency collaborative optimization mechanism: Dynamic dimming of sensors (10-level stepless adjustment) combined with the dustproof and waterproof properties of IP65 ensures long-term light transmittance and low failure rate, with a daily comprehensive energy-saving rate of 65% and the light decay cycle extended to 50,000 hours.

◎Practical effects in multiple scenarios: In scenarios such as coastal typhoon areas, chemical explosion-proof areas, and rural areas without power grids, it has achieved effects such as zero damage against typhoons, safe operation in explosion-proof environments, and a 3-fold increase in battery life in cloudy and rainy days, reducing maintenance costs by up to 80%.

Multi-sensor Fusion

The Automatic LED Street Light builds a full-dimensional perception system of "light-human-vehicle-environment" through the collaborative work of four sensors, realizing dynamic and precise adjustment of lighting power.

Technical analysis of four core sensors

Sensor Type	Technical Principle	Function Positioning	Technical Advantages
Microwave radar sensor	Emits 24GHz microwave signals, detects the speed and distance of moving objects through the Doppler effect	Identifies vehicles/pedestrians within 5-15 meters, distinguishes movement direction (approaching/away)	Strong anti-rain and fog interference ability (attenuation <5%), detection accuracy ≥98%
Infrared human body induction module	Detects human infrared radiation (wavelength 9-14μm) using pyroelectric effect	Supplements radar blind spots (range <3 meters), identifies stationary human bodies (such as pedestrians staying)	Power consumption only 0.1W, standby current <10μA
Photosensitive sensor	Based on CdS photoresistor, spectral response range 400-1100nm	Monitors ambient illuminance in real time, automatically switches between day/night modes	Response time <10ms, dark current <1nA
Temperature and humidity sensor	Integrates SHT31 digital chip, measurement range -40℃~120℃ (humidity 0-100%RH)	Compensates LED light decay according to temperature, starts heating and defogging function when humidity exceeds the limit	Accuracy ±0.3℃ (temperature), ±2%RH (humidity), data refresh rate 1Hz

Sensor collaborative control logic

◎Day mode: When the photosensitive sensor detects illuminance >1000lx, the LED light source is turned off, and the sensor enters a low-power monitoring state;

◎Night mode: When illuminance <50lx, the system starts:

◎Unmanned state: LED maintains 10% basic brightness (about 3W power);

◎When someone/vehicle approaches: After the radar detects a moving object, the brightness is increased to 100% (30W) 2 seconds in advance, and returns to basic brightness 30 seconds after the pedestrian leaves;

◎Special scenarios: When the temperature and humidity sensor detects temperature < -10℃ or humidity >90%, the brightness is automatically increased by 20% to compensate for visibility.

IP65 Protection Rating

As outdoor equipment, street lights need to withstand long-term erosion from rain, dust, salt spray, ultraviolet rays, etc. The IP (Ingress Protection) rating is a core indicator to measure the sealing performance of equipment. The IP65 rating adopted by the Automatic LED Street Light achieves a qualitative leap in dustproof and waterproof capabilities compared with traditional IP54 products.

Technical Comparison Between IP65 and IP54

Protection Rating	Dustproof Ability	Waterproof Ability	Applicable Scenarios
IP54	Prevents accumulation of harmful dust (particles with diameter ≥1mm cannot enter)	Prevents water spraying from all directions (water column diameter 12.5mm, distance 3 meters, lasting 10 minutes)	Ordinary industrial areas, coastal areas with low salt spray
IP65	Completely dustproof (no dust entry)	Prevents low-pressure water jet spraying (water column diameter 6.3mm, distance 3 meters, lasting 3 minutes)	Coastal areas with high salt spray, chemical plants, deserts, areas with frequent heavy rains

◎Dustproof: IP65 requires the design of an internal pressure balance valve to prevent dust from infiltrating through the vent;

◎Waterproof: IP65 needs to pass the "spray + immersion" dual test (no leakage after immersion in 1-meter deep water for 30 minutes), while IP54 only needs the spray test;

◎Sealing materials: IP65 adopts silicone rubber O-rings (temperature resistance -50℃~200℃) and ultrasonic welding technology, with a sealing life 5 times longer than that of the ordinary rubber pad used in IP54.
