Abstract

A light-emitting diode device is disclosed. The light-emitting diode device includes a transparent substrate with a first surface, a second surface opposite to the first surface, and a side surface connected to the first surface and the second surface; a first light-emitting structure; a second light-emitting structure; a connecting layer, connected to the first light-emitting structure and the second light-emitting structure; a circuit arranged between the transparent substrate and the first light-emitting structure, and having a portion formed on the first surface without extending to the second surface; and a structure with diffusers, covering the first light-emitting structure and the second light-emitting structure on the first surface without crossing over the side surface.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A light-emitting device, comprising:
 a transparent substrate having a first surface, a second surface opposite to the first surface, and a side surface connected to the first surface and the second surface;   a first light-emitting structure;   a second light-emitting structure;   a connecting layer, connected to the first light-emitting structure and the second light-emitting structure, and disconnected from the transparent substrate;   a circuit arranged between the transparent substrate and the first light-emitting structure, and having a portion formed on the first surface without extending to the second surface; and   a structure with diffusers, covering the first light-emitting structure and the second light-emitting structure on the first surface without crossing over the side surface.   
     
     
         2 . The light-emitting device of  claim 1 , further comprising an intermediate substrate arranged between the first light-emitting structure and the second light-emitting structure. 
     
     
         3 . The light-emitting device of  claim 1 , further comprising a carrier connected to the side surface and separated from the second surface. 
     
     
         4 . The light-emitting device of  claim 3 , wherein the transparent substrate is arranged against the carrier by an angle of 45-135 degrees. 
     
     
         5 . The light-emitting device of  claim 3 , further comprising a reflector arranged on the carrier. 
     
     
         6 . The light-emitting device of  claim 3 , wherein the carrier is a printed circuit board, a ceramics substrate, or a silicon substrate. 
     
     
         7 . The light-emitting device of  claim 3 , wherein the carrier comprises a top surface which is covered by the structure with diffusers. 
     
     
         8 . The light-emitting device of  claim 1 , wherein the first light-emitting structure comprises a first upper surface, a first lower surface opposite to the first upper surface and facing the connecting layer, and a first bonding pad formed on the first upper surface. 
     
     
         9 . The light-emitting device of  claim 8 , further comprising a reflective layer arranged on the first lower surface. 
     
     
         10 . The light-emitting device of  claim 1 , wherein the first light-emitting structure and the second light-emitting structure are configured to emit different color lights. 
     
     
         11 . The light-emitting device of  claim 1 , wherein the first light-emitting structure and the second light-emitting structure are configured to emit a blue light and a red light. 
     
     
         12 . The light-emitting device of  claim 1 , wherein the first light-emitting structure and the second light-emitting structure are electrically connected to each other in series. 
     
     
         13 . The light-emitting device of  claim 1 , wherein the first light-emitting structure and the second light-emitting structure are electrically connected to each other in parallel. 
     
     
         14 . The light-emitting device of  claim 1 , wherein the connecting layer is made of insulating material or conductive material. 
     
     
         15 . The light-emitting device of  claim 1 , wherein the transparent substrate comprises a phosphor material.
