| 20080276508 | LIGHT EMITTING DIODE FOR ELECTRIC SIGNBOARD - Disclosed is a Light Emitting Diode (LED) for an electric signboard. The LED can prevent formation of shade caused by a coated silicon layer while minimizing the weight and thickness of the electric signboard. Further, the LED protects an internal LED chip by using a transparent hemispheric cap having scattering property, and a chip die is mounted on a Printed Circuit Board (PCB) while closely making contact with the surface of the PCB, so that thickness and weight of silicon coated on the surface of the PCB can be minimized. | 11-13-2008 |
