Light emitting device

Abstract

A light emitting device comprises a light emitting element disposed within a space surrounded by a reflective surface of a reflector disposed on a board. A lower portion of the reflector is placed within a recess formed in the board, and a side wall of the recess is interposed between the lower end of the reflective surface of the reflector and the light emitting element.

What is claimed is: 
     
         1 . A light emitting device comprising:
 a board;   a reflector disposed on a surface of said board; and   a light emitting element disposed within a space surrounded by a reflective surface of said reflector,   wherein the bottom of said reflector is adhered on the surface of said board with a resin which is capable of reflecting light emitted from said light emitting element.   
     
     
         2 . A light emitting device comprising:
 a board;   a reflector disposed on a surface of said board; and   a light emitting element disposed within a space surrounded by a reflective surface of said reflector,   wherein only a partial area of the bottom of said reflector, which is in contact with a lower end of the reflective surface, is adhered on the surface of said substrate with a resin which is capable of reflecting light emitted from said light emitting element.   
     
     
         3 . The light emitting device according to  claim 1 , wherein said resin is a white silicon-based resin, a white acrylic-based resin, or an epoxy-based resin containing a reflective material. 
     
     
         4 . The light emitting device according to  claim 2 , wherein said resin is a white silicon-based resin, a white acrylic-based resin, or an epoxy-based resin containing a reflective material. 
     
     
         5 . The light emitting device according to  claim 1 , wherein said board is laid on a base board made of a metal. 
     
     
         6 . The light emitting device according to  claim 2 , wherein said board is laid on a base board made of a metal. 
     
     
         7 . The light emitting device according to  claim 1 , wherein said light emitting element is encapsulated with a resin filled in said space, and said resin contains a material excited by light emitted by said light emitting element to emit light at a wavelength different from that of the light emitted from said light emitting element. 
     
     
         8 . The light emitting device according to  claim 2 , wherein said light emitting element is encapsulated with a resin filled in said space, and said resin contains a material excited by light emitted by said light emitting element to emit light at a wavelength different from that of the light emitted from said light emitting element. 
     
     
         9 . The light emitting device according to  claim 1 , further comprising a sheet including a material which is excited by light emitted by said light emitting element to emit light at a wavelength different from that of the light emitted by said light emitting element, said sheet being disposed inside or outside of said space, or disposed both inside and outside of said space. 
     
     
         10 . The light emitting device according to  claim 2 , further comprising a sheet including a material which is excited by light emitted by said light emitting element to emit light at a wavelength different from that of the light emitted by said light emitting element, said sheet being disposed inside or outside of said space, or disposed both inside and outside of said space.
