摘要:
针对发光二极管(LED)广告灯箱近距离、大面积、非对称照明的特点,提出一种基于配光曲线的LED广告灯箱反射面矢量设计方法.根据目标面照度分布要求,对比添加反射面前的目标面照度变化,得到满足均匀照明的广告灯箱配光曲线.使用剪裁法确定反射面的斜率,建立直射光线和反射光线的有效叠加和补偿,实现均匀照明的要求.运用LightTools软件对设计进行模拟仿真,结果表明:目标照度均匀度达到85%,能量利用率超过80%.
Abstract:
In consideration of the properties of asymmetric large-area illustration at a short distance, a vector design method based on distribution curve for light emitting diode(LED)advertisement lamp boxes is proposed. According to the illumination requirement of the illumination distribution without reflector in target surface, the distribution curve of advertising light that satisfies the uniform illumination is calculated. Using the tailored to determine the slope of the reflector, and then establish effective superposition and compensation of direct light and reflected light, thus achieving designed uniform illumination on the surface. The simulation result by LightTools shows that the uniformity of illumination reaches 85% and the energy efficiency exceeds 80%.
