摘　　要：针对传统LED日光灯存在的散热难、光线刺眼、光衰较大的缺陷,从散热器、二次光学设计、电源驱动三个方面进行了研究和设计,提出了翼状叠片式结构的散热器设计、新型LED阵列及双层花生米透镜的二次光学设计和斩波群技术控制的PWM脉冲驱动方式。实验表明,其散热效果是传统铜板散热器的2-3倍,照度均匀度高达0.856,完全满足日常照明的要求。The radiator of alary lamination was designed for hard radiation of traditional LED daylight lamp. Secondary optics design methods of new LED array and double peanut lens were proposed for the blinding light of traditional LED daylight lamp. Driving mode of PWM pulse based on technology of chopper group was designed for large lighting decay. The experimental results show that the heat dissipation capability of alary lamination radiator is 2-3 times of traditional copper radiator. The uniformity of illumination is up to 0. 856. It meets the requirements of daily lighting completely.
