摘要
根据光在均匀介质中的折射原理,从理论上分析了LED灯具透镜引起色散的原因。针对因折射而产生的色散现象,提出了降低色散影响的若干措施,并以RGB投光灯为例,设计了一个带微透镜阵列的全内反射透镜。模拟和实验结果表明,该透镜能对R、G、B三种光线实现较为一致的发光角度和光强分布。
According to the refraction law of light in homogeneous medium, this paper theoretically analyzes the reason that the lenses in LED lamps cause light dispersion. For the dispersion phenomenon caused by refraction, several methods were proposed to reduce the impact of dispersion. A total internal reflection lens with micro-lens array was designed for RGB projector light. The simulation and experimental results showed that view angle and light distribution can be coineidently achieved with the designed lens for light of Red, Green and Blue.
