基于LED大功率扩展光源的二次光学设计

在目前的低碳环境下,LED照明光源逐步替代传统光源,但是由于其本身结构和自身特点,要进行高效的光能利用与照明,必须进行适当的光学设计以便改善光能分布。笔者首先阐述了LED的光学特性及二次光学设计,其次对LED大功率扩展光源的二次光学设计进行了深入探讨。

In the current low carbon environment, LED lighting light source gradually replace the traditional light source, but because of its own characteristics and structure, which carry, out efficient energy utilization and lighting, must be proper optical design so as to improve the light energy distribution.The author first expounds the optical properties of leds and the secondary optical design, secondly for high power LED light source expanding secondary, optical design has carried on the deep discussion.
