    • A reflector system for a lighting device. The system uses two reflective surfaces to redirect the light before it is emitted. The light source/sources (102) are disposed at the base of a secondary reflector (106). The first reflective surface is provided by a primary reflector (104) which is arranged proximate to the source/sources. The primary reflector (104) initially redirects, and in some cases diffuses, light from the sources such that the different wavelengths of light are mixed as they are redirected toward the secondary reflector (106). The secondary reflector functions primarily to shape the light into a desired output beam. The primary and secondary reflectors may be specular or diffuse and may comprise faceted surfaces. The reflector arrangement allows the source to be placed at the base of the secondary reflector where it may be thermally coupled to a housing or another structure to provide an outlet for heat generated by the sources.
    • 一种用于照明装置的反射器系统。 该系统使用两个反射表面来重新定向发光前的光。 光源/源(102)设置在次级反射器(106)的基部。 第一反射表面由靠近源/源设置的主反射器(104)提供。 主反射器(104)最初重定向并且在某些情况下扩散来自光源的光,使得不同波长的光在被重定向到次级反射器(106)时被混合。 次级反射器主要用于将光成形为期望的输出光束。 初级和次级反射器可以是镜面的或漫射的,并且可以包括刻面。 反射器布置允许源放置在次级反射器的基座处,其中它可以热耦合到壳体或另一结构以提供由源产生的热量的出口。
