具有纹理化反射器的灯具
摘要：
本发明公开了具有纹理化反射器表面的灯具。本发明实施方案提供了照明系统，在所述照明系统中LED面对，并且来自LED光源的大多数光入射于背式反射器(108，408，508，808，1008，1208)的纹理化表面上，同时产生光源的最小眩光和最小成像。该反射器(108，408，508，808，1008，1208)可称为回射器。灯具(100，800，1000，1100，1300)的反射器(108，408，508，808，1008，1208)可由相对廉价的材料制成，诸如聚碳酸酯，在无纹理情况下，所述材料具有镜面或半镜面表面。所述材料(410，510，1109，1309)可单独或与金属衬底(1107，1307)一起使用以形成反射器(108，408，508，808，1008，1208)。纹理化表面可通过压印图案或通过粗糙化进行纹理化，并且可进行挤压。可使用棱镜纹理。纹理也可在空间上变化。
摘要（英）：

A light fixture with a textured reflector surface is disclosed. Embodiments of the present invention provide for a lighting system in which LEDs face, and the majority of light form the LED light source is incident on, a textured surface of a back reflector (108, 408, 508, 808, 1008, 1208) while producing minimal glare and minimal imaging of the light source. Such a reflector (108, 408, 508, 808, 1008, 1208) may be referred to as a retro-reflector. The reflector (108, 408, 508, 808, 1008, 1208) for the light fixture (100, 800, 1000, 1100, 1300) can be made from a relatively inexpensive material such as polycarbonate, which without texturing has a specular or semi-specular surface. This material (410, 510, 1109, 1309) can be used alone or with a metal substrate (1107, 1307) to form the reflector (108, 408, 508, 808, 1008, 1208). The textured surface can be textured by way of an imprinted pattern or by roughening, and can be extruded. A prismatic texture may be used. The texturing can also be spatially varied.
