Product Introduction
◎Value of high-power design: The 400W LED street light achieves a coverage radius of 35 meters and an illuminance uniformity of 0.72 through optical optimization, increasing the coverage area by 300% compared to traditional solutions. Meanwhile, it has a luminous efficiency of 180lm/W, saves 75% energy, and supports 20%-100% intelligent dimming.
◎Breakthrough in heat dissipation technology: Adopting a vacuum cavity phase change heat dissipation system with a thermal diffusion rate of 12,000W/m²·K and a thermal resistance of only 0.08℃/W, the heat dissipation efficiency is 6 times higher than that of traditional aluminum materials, with an MTBF of 100,000 hours.
◎Full-scenario adaptability: Supports wide-temperature operation from -40℃ to 70℃, is explosion-proof certified for industrial areas, integrates environmental sensors to build IoT nodes, and has application capabilities in extreme environments such as polar scientific expeditions.
Strategic Value of High-Power Design
Revolutionary improvement in coverage radius and illuminance uniformity
◎Horizontal coverage radius: 35 meters (irradiation area up to 3846㎡, 300% higher than 200W)
◎Vertical illuminance: At a 12-meter pole height, the average road surface illuminance reaches 50lux (national standard for main roads requires ≥30lux)
◎Uniformity: 0.72 (traditional design only 0.4-0.5), eliminating the "zebra effect" and dark areas
Quantum leap in energy efficiency ratio
The 400W LED Street Light adopts the sixth-generation gallium nitride (GaN) chip and fluorescent ceramic conversion technology, achieving:
◎Luminous efficiency: 180lm/W (industry average 140lm/W), 75% more energy-saving than traditional high-pressure sodium lamps (100lm/W)
◎Color rendering index: Ra≥80 (traditional sodium lamps only 20-30), restoring the true color of objects and improving nighttime driving safety
◎Color temperature: 5000K neutral white light, balancing visual comfort and penetration (visibility in foggy days increased by 30%)
Power flexibility of intelligent dimming system
Equipped with a dual-core microprocessor and ambient light sensing network
◎Dynamic power adjustment: Automatically adjust output power (20%-100% stepless dimming) according to traffic flow, time, and weather
◎Regional linkage control: Realize cluster management of 100 street lights through LoRa/4G modules, with response time <100ms
◎Emergency mode: Automatically switch to UPS power supply when the power grid fails, maintaining 30% brightness for 8 hours continuously
Heat Dissipation System
Innovation in the physical mechanism of heat dissipation technology
The 400W LED Street Light innovatively adopts a vacuum cavity vapor chamber (VC) + microchannel condenser phase change heat dissipation system.
◎Working principle
Heat generated by the chip is quickly conducted to the vacuum cavity through the nano-coating interface
The working medium (propane/R134a) in the cavity vaporizes, bringing heat to the condensation end
The microchannel structure accelerates the condensation and reflux of the working medium, forming a continuous phase change cycle
◎Core parameters
Thermal diffusion rate: 12,000W/m²·K (traditional aluminum only 2,000W/m²·K)
Thermal resistance: Only 0.08℃/W
Heat dissipation area: 0.8㎡ (traditional fins only 0.3㎡)
Product Advantages
◎High-power lighting
◎Phase change heat dissipation system
◎Vacuum cavity vapor chamber
◎Intelligent dimming
◎Ultra-long service life
