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.

Abstract: A lighting lamp includes a light guide board, which is directly mounted in the cavity of a lamp holder, furniture, utensil, or the construction of a building, having a clear transmissive layer at the front side and a continuous piece of reflective layer a clear transmission layer at the front side and a reflective layer at the back side that has the shape of an umbrella surface and sloping from the periphery toward its center, and a plurality of LEDs mounted within the cavity outside the light guide board and controlled to emit light laterally into the inside of the light guide boards to provide a uniform lighting effect having an enhanced brightness without multi-image and to simulate the lighting effect of a ball lamp.

Abstract: A light-guide board includes a light guide plate made out of an optically transmissive material and having a transparent layer and a back reflecting layer formed integral with the back side of the transparent layer, and a plurality of reflecting baffles respectively extending from the back reflecting layer and embedded in the transparent layer for reflecting light to enhance the intensity of light and the uniformity in light intensity.
