Abstract
In this paper, we study a method of designing a reflector for LED light sources with an asymmetric light distribution. In a sports game, lighting with a symmetric distribution makes the athlete and spectators look directly at the light source
在体育比赛中，当运动员和观众直接看到光源时，就会产生耀眼的眩光，出现白出局现象。这有可能妨碍选手们的运动能力下降和比赛集中，因此为了不让光源直接暴露出来，需要具备非对称背光的运动照明。特别是网球是球快速移动的运动之一，随着球的不同，选手及观众的视线也会移动，因此设计及布置适当的照明是必需的。图1是目前广泛使用的透光灯形态的运动照明，由于背光的分布是以光源为中心的对称形态，所以设置时将照明器具直接tilt布置在赛场上。在这种情况下，选手和观众会直接看到光源，照明的直接光会引起耀眼，给比赛的进行带来问题。因此，为了减少耀眼，应该使用具有非对称背光的运动照明。图2是一种具有非对称背光的运动照明，以光源为中心，具有非对称背光分布。照明的不对称角度考虑光照度的分布设定为50°以上，考虑到选手视线高度的耀眼度设定为60°以下，具有不对称背光的情况下，可以在没有照明器具tilt的情况下设置，可以将耀眼度最小化。但是像上面一样使用金属清真作为光源使用的spots照明的维护保修费用和耗电量高的单Design of a Reflector for LED Light Sources with Asymmetric Light Distribution
