摘 要:提出了一种基于自由曲面底板的LED配光新方法,采用TracePro软件设计自由曲面并进行仿真分析。结果表明:将LED芯片直接贴装在带有自由曲面的底板上,可以获得较大的出光角度,半光强角达到60°,比传统反光杯的配光方式获得的半光强角增大25°。此外,通过这种新方法可获得高光效和高均匀照度的照明模式,在实现相同的目标平面平均照度时,总光通量比传统配光方式减少25%,照度的衰减减少了60%。通过调节自由曲面底板的形状进行配光,可根据需要获得不同的照明效果,实现高品质的LED照明。
A novel method for light distribution based on the substrate with freeform surface is proposed. The freeform surface substrate is designed and stimulated by using the TracePro software. The stimulation results show that a large luminous intensity angle can be achieved by adjusting the LED chips directly onto the substrate with freeform surface. The half-intensity angle is 60° , 25° bigger than using the tradition reflection cup. Furthermore, a lighting with high light efficiency and uniform illumination can be achieved by using this method. When a same average horizontal illuminance is created, it costs 25% less luminous flux and avoids 60% less luminous decay than using the traditional method. By adjusting the shape of the freeform surface to distribute the LEDs′ light, not only the other patterns of luminous effects are conveniently get, but also a high quality of LED lighting can be achieved.
