Typically employs high-power LED modules or high-lumen COB light sources,paired with multi-faceted reflectors or symmetrical lenses to produce wide beam angles(e.g.,90°x 120°)for flood illumination.Luminaires are equipped with efficient active or passive cooling systems(e.g.,heat pipes,fin arrays)to ensure stable operation at high power.A key feature is the integrated electric lowering system(winch,cable)which lowers the entire luminaire array to ground level for safe and convenient maintenance.The luminaire array structure is robust enough to withstand high-altitude strong winds.
Single luminaire power ranges from 500W to over 2000W,with luminous flux output reaching hundreds of thousands of lumens.Symmetrical or asymmetric light distributions are available based on coverage needs.Operating voltage is AC380V three-phase or AC220V single-phase input.Protection rating is high at IP65/IP66.Wind resistance rating is designed based on pole height(e.g.,withstands 60m/s wind pressure).Luminaires usually have horizontal and vertical adjustment mechanisms for precise aiming.The lowering system operates smoothly with fall-prevention safety devices.
Primarily installed in airport aprons,large transportation hub squares,container yards,power plant coal yards,and large outdoor parking lots.The design involves calculations for pole height,luminaire array configuration(number and power of lights),and aiming angles based on illuminance and uniformity standards.This high-mast concentrated lighting method effectively reduces shadows caused by ground obstacles,provides a glare-free working environment,and significantly saves on cable usage and foundation quantities,lowering overall investment costs.
