LIGHT GUIDE PLATE DESIGN FOR ASYMMETRIC LIGHTING

Abstract

A lighting assembly (100) including a plurality of light sources (102), a light guide plate (106), a back reflector (110), a front collector (114), and a plurality of microstructures (124) is provided. The light sources are configured to generate light and are arranged on a PCB (118). The light guide plate (106) is arranged to receive the light generated by the light sources (102). The light guide plate (106) and the plurality of light sources (102) are separated by a gap (108). The back reflector (110) is arranged along a first surface (112) of the light guide plate (106). The front collector (114) is arranged below a second surface (116), opposite the first surface (112), of the light guide plate (106). The front collector (114) is also arranged across the gap (108) separating the light guide plate (106) from the plurality of light sources (102). The microstructures (124) are arranged on the first surface (112) of the light guide plate (106) and are arranged in a pattern to provide an asymmetric light distribution (200).
