Abstract

A light emitting device include a plurality of arrayed light emitting elements, each light emitting element including a plurality of side faces; at least one light reflecting member that covers the side faces of each of the light emitting elements; and at least one light blocking member disposed in between light emitting elements and disposed separated from the light emitting elements.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A light emitting device comprising:
 a plurality of arrayed light emitting elements, each light emitting element including a plurality of side faces;   at least one light reflecting member that covers the side faces of each of the light emitting elements; and   at least one light blocking member disposed in between light emitting elements and disposed separated from the light emitting elements.   
     
     
         2 . The light emitting device according to  claim 1 , further comprising
 at least one translucent member that covers at least one upper face of the light emitting element,   the light reflecting member covers side faces of the translucent member.   
     
     
         3 . The light emitting device according to  claim 2 , wherein
 the light blocking member is disposed between the light reflecting members that cover the side faces of the translucent member and is disposed in between the light emitting elements.   
     
     
         4 . The light emitting device according to  claim 1 , wherein
 the light emitting elements are joined on a base material and   an embedding material is embedded between the base material and the light emitting elements.   
     
     
         5 . The light emitting device according to  claim 4 , wherein
 the embedding material is formed from a light reflecting resin.   
     
     
         6 . The light emitting device according to  claim 2 , wherein
 upper faces of the translucent member, the light reflecting member and the light blocking member substantially lie on the same plane.   
     
     
         7 . The light emitting device according to  claim 1 , wherein
 a plurality of light emitting elements are mounted on the base material so as to be independently driven according to a wiring pattern of the base material.   
     
     
         8 . The light emitting device according to  claim 1 , wherein
 the light reflecting member has a groove at between the light emitting elements, and the light blocking member is disposed in a groove formed in the light reflecting member.   
     
     
         9 . The light emitting device according to  claim 8 , wherein
 the groove is disposed extending to the ends of the light reflecting members.   
     
     
         10 . The light emitting device according to  claim 1 , wherein
 the light blocking member is disposed in a straight line between the light emitting elements.   
     
     
         11 . A light emitting device comprising:
 a plurality of arrayed light emitting elements, each light emitting element including a plurality of side faces;   light reflecting members that covers the side faces of each of the light emitting elements; and   at least one light blocking member disposed between the light reflecting members in between light emitting elements.   
     
     
         12 . The light emitting device according to  claim 11 , further comprising
 at least one translucent member that covers at least one upper face of the light emitting element,   the light reflecting member covers side faces of the translucent member.   
     
     
         13 . The light emitting device according to  claim 12 , wherein
 the light blocking member is disposed between the light reflecting members that cover the side faces of the translucent member and is disposed in between the light emitting elements.   
     
     
         14 . The light emitting device according to  claim 11 , wherein
 the light emitting elements are joined on a base material and   an embedding material is embedded between the base material and the light emitting elements.   
     
     
         15 . The light emitting device according to  claim 14 , wherein
 the embedding material is formed from a light reflecting resin.   
     
     
         16 . The light emitting device according to  claim 12 , wherein
 upper faces of the translucent member, the light reflecting member and the light blocking member substantially lie on the same plane.   
     
     
         17 . The light emitting device according to  claim 11 , wherein
 a plurality of light emitting elements are mounted on the base material so as to be independently driven according to a wiring pattern of the base material.   
     
     
         18 . The light emitting device according to  claim 11 , wherein
 the light reflecting member has a groove at between the light emitting elements, and the light blocking member is disposed in a groove formed in the light reflecting member.   
     
     
         19 . The light emitting device according to  claim 18 , wherein
 the groove is disposed extending to the ends of the light reflecting members.   
     
     
         20 . The light emitting device according to  claim 11 , wherein
 the light blocking member is disposed in a straight line between the light emitting elements.
