发明名称 Shaped Reflectors for Enhanced Optical Diffusion in Backlight Assemblies
摘要 An assembly for diffusing a plurality of light sources. A diffusing device is placed adjacent to the plurality of light sources and preferably contains a plurality of shaped reflectors placed on the diffusing device where a shaped reflector is positioned adjacent to each light source. The shaped reflectors are placed in a one-to-one relationship with the light sources, which can be LED or fluorescent or any other type of light source. The reflectors may be single-tone, multi-tone, or gradient-tone and generally have a higher amount of reflectivity near the central axis of the light source and a lower reflectivity away from the central axis of the light source. The shaped reflectors may be used in both direct-lit and edge-lit orientations.
