LED 道路照明光衰预补偿技术研究

摘要

The pre-compensation technologies of light attenuation in LED road lighting are presented in combination with the specific application of LED road lamps in urban roads lighting design. Introductions to the principle for the light attenuation compensation controller, light attenuation characteristics of the LED road lamps, corresponding road illuminance change of the light attenuation, and the connection between the drive current and the luminous flux are available as well.%　　结合 LED 路灯在城市道路照明设计中的具体应用情况，阐述 LED 路灯光衰预补偿技术。介绍光衰补偿控制器的原理、 LED 路灯的光衰特性、光衰对应的路面照度变化、驱动电流与光通量的关系等。
