Attorney, Agent or FirmInternational ClassF21V 007/00AbstractA light reflector includes a plurality of opaque, generally triangular panels connected together to form a three dimensional geometric figure surrounding an inside space. Each panel has a reflective surface facing the inside space and each corner of each of the panels is adjacent a corner of an adjacent panel. The panels are spaced apart from each other by rectangular, open areas. An artifical light source is placed inside the inside space. The reflective surfaces relect light from the artificial light source and direct reflected light toward the rectangular open areas. Plants are situated adjacent the rectangular open areas and receive light emanating therefrom.Other References
