Abstract
A LED lighting fixture includes a light guide board, which is made of a high transmissive material and directly mounted in the cavity of a lamp holder, furniture, utensil, or the construction of a building, having a clear base layer at the front side and a continuous piece of reflective layer with a corrugated cross section at the back side, and a plurality of LEDs mounted within the cavity outside the light guide board and controlled to emit light transversely into the inside of the light guide boards for reflection by the reflective layer to increase the angle of illumination and to provide a uniform lighting effect having an enhanced brightness without multi-image and flashing.
Claims7
A LED lighting fixture comprising:
- a cavity;
- a light guide board made of a transmissive material and mounted inside said cavity, said light guide board comprising a clear base layer at a front side thereof and a continuous piece of reflective layer at a back side thereof, said reflective layer having a corrugated cross section, said reflective layer comprising two straight end edges, two arched shoulder portions respectively extended from said two straight end edges on the middle and respectively terminating in a V-shaped tip;
- and
- a plurality of LEDs mounted within said cavity outside said light guide board and adapted to emit light transversely into the inside of said light guide board from two opposite lateral sides for reflection by said reflective layer to increase the angle of illumination and to provide a uniform lighting effect having an enhanced brightness without causing multi-image and flashing.

A LED lighting fixture comprising:
- a lamp holder, said lamp holder defining therein a cavity
- a light guide board made of a transmissive material and mounted inside said cavity, said light guide board comprising a clear base layer at a front side thereof and a continuous piece of reflective layer at a back side thereof, said reflective layer having a corrugated cross section, said reflective layer comprising two straight end edges, two arched shoulder portions respectively extended from said two straight end edges on the middle and respectively terminating in a V-shaped tip;
- and
- a plurality of light emitting diodes mounted within said cavity outside said light guide board and adapted to emit light transversely into the inside of said light guide board from two opposite lateral sides for reflection by said reflective layer to increase the angle of illumination and to provide a uniform lighting effect having an enhanced brightness without causing multi-image and flashing.

A LED lighting fixture comprising:
- a cavity;
- a light guide board made of a transmissive material and mounted inside said cavity, said light guide board comprising a clear base layer at a front side thereof and a continuous piece of reflective layer at a back side thereof, said clear base layer comprising a light input surface disposed at one lateral side thereof and a light output surface disposed at a front side thereof and abutted against said light output surface at an angle, said reflective layer having a corrugated cross section and an inner side bonded to the whole surface area of said clear base layer beyond said light input surface and said light output surface, the inner side of the reflective layer comprising a flat base portion disposed abutted to one side of said light input surface, a curved tail portion abutted against one side of said light output surface opposite to said light input surface, a sloping portion connected between said flat base portion and said tail portion, and a great arched portion connected between said flat base portion and said sloping portion;
- and
- a plurality of light emitting diodes mounted within said cavity outside said light guide board and adapted to emit light through said light input surface into the inside of said light guide board for reflection by said reflective layer toward said light output surface to increase angle of illumination and to provide a uniform lighting effect having an enhanced brightness without causing multi-image and flashing.
