Lighting assembly

Abstract

A lighting assembly includes a light source, a light guiding plate and a reflecting member. The light guiding plate has a light input surface, a light output surface extending from the light input surface, a connecting surface and a reflecting surface. The connecting surface has an inclined segment. Extensions of the inclined segment and the light output surface cooperatively define a first included angle. The reflecting surface interconnects the connecting surface and the light output surface, cooperates with the light output surface to define a second included angle, and mounted with the reflecting member. A thickness of the light guiding plate at the reflecting surface is greater than that at the light input surface.

What is claimed is: 
     
         1 . A lighting assembly comprising:
 a light source capable of emitting light;   a light guiding plate having
 a light input surface, 
 a light output surface that extends from said light input surface, 
 a connecting surface that is opposite to said light output surface, and that has an inclined segment inclining away from said light output surface, extensions of said inclined segment and said light output surface cooperatively defining a first included angle therebetween, and 
 a reflecting surface that interconnects said connecting surface and said light output surface, and that cooperates with said light output surface to define a second included angle therebetween, a thickness of said light guiding plate at said reflecting surface being greater than that at said light input surface; and 
   a reflecting member for reflecting light emitted from said light guiding plate back into said light guiding plate.   
     
     
         2 . The lighting assembly of  claim 1 , wherein said connecting surface further has a straight segment that is connected between said inclined segment and said second edge of said light input surface, and that is parallel to said light output surface. 
     
     
         3 . The lighting assembly of  claim 1 , wherein said light source includes a plurality of light emitting diodes (LEDs) disposed linearly along an axis. 
     
     
         4 . The lighting assembly of  claim 3 , wherein the length of said light input surface is extended along said axis. 
     
     
         5 . The lighting assembly of  claim 1 , wherein said light input surface is a flat surface without serration. 
     
     
         6 . The lighting assembly of  claim 1 , wherein the length a projection of said light output surface on said connecting surface is greater than the length of said connecting surface. 
     
     
         7 . The lighting assembly of  claim 1 , wherein said reflecting surface of said light guide plate is covered by said reflecting member, and no surface of said light guiding plate other than said reflecting surface is covered. 
     
     
         8 . The lighting assembly of  claim 1 , wherein said reflecting surface is slanted with a constant slope rate. 
     
     
         9 . The lighting assembly of  claim 1 , wherein said light output surface is directly exposed to surroundings without being covered. 
     
     
         10 . The lighting assembly of  claim 1 , wherein said light connecting surface is mirror surface without sandblasting.
