ABSTRACT:
A LED lighting fixture includes a cavity receiving a light guide board, and a plurality of LEDs mounted within two reinforcing parallel grooves formed in the light guide board along the length of corresponding opposite lateral sides. The light guide board further includes a clear base portion made of a light transmissive material, and a continuous reflective layer disposed over a surface of the clear base portion, the reflective layer having a portion protruding into the clear base portion. Light from the LEDs is injected transversely into the inside of the light guide board for reflection by the reflective layer to be ejected from the lighting fixture through a surface of the light guide board.
