摘要： Optical components for lighting devices and lighting devices including such components are described. In some embodiments the optical components are in the form of a lens that alter the distribution of light produced by a lighting fixture. In some embodiments, the lenses are in the form of a downlight to wallwash lens which, when placed in a downlight fixture, convert the light distribution to that of a wallwash fixture, e.g., causing the downlight to produce an off-axis light distribution, without changing the fixture. The lens includes a body with a light source facing side and an opposite room facing side having two optically active regions, each including structures that redirect a portion of light received through the light source facing side and incident thereon. The first region includes structures that redirect, via refraction, and the second region includes structures that redirect, in part via total internal reflection.

摘要： A luminaire includes a plurality of solid state light sources arranged to emit light in respective angular distributions that are centered along a common optical axis. A reflector including one or more reflecting surfaces is arranged along a periphery of the solid state light sources. The reflector is positioned to receive light emitted at relatively high propagation angles from the solid state light sources, with respect to the optical axis, and reflects the light to have reduced propagation angles, with respect to the optical axis. The one or more reflecting surfaces have a generally flat cross-section that is angled away from the optical axis, and are arranged in a pattern around the periphery of the solid state light sources. The one or more reflecting surfaces can reflect specularly or diffusely.

摘要： A luminaire is provided to redirect incidence light from one or more solid state light sources to a batwing distribution with both tunable peak angle and beam width. The peak angle is able to be tuned from 90 degree to 0 degree from the incidence direction with very high efficiency. The beam width is able to be tuned with either narrow beam angle solid state light sources for high efficiency or TIR lens or the optical properties of a reflector for versatility. Uniform illuminance distribution is thus achieved across a wide field with or without a prism or diffuser cover.
摘要翻译：提供照明器以将来自一个或多个固态光源的入射光重定向到具有可调峰值角和光束宽度的蝙蝠分布。峰值角度能够以非常高的效率从入射方向从90度调整到0度。波束宽度能够用于高效率的窄光束角固态光源或TIR透镜或用于多功能性的反射器的光学特性来调谐。因此，在具有或不具有棱镜或扩散器盖的宽场中实现均匀的照度分布。
