LIGHT EMITTING DIODE BULB FOR GENERATING WIDE ANGLE ILLUMINATION CAPABLE OF OBTAINING WIDE AND UNIFORM ILLUMINATION BY PROJECTING A RAY TO A WIDE ANGLE

摘要

PURPOSE: A light emitting diode bulb for generating wide angle illumination is provided to secure manufacturing costs and long lifetime using an LED bulb.;CONSTITUTION: A circuit board(20) is formed in one end of one or more lamp socket heat dissipating modules(10). One or more light emitting diodes(30) is arranged on the circuit board. The light emitting diode is arranged on the circuit board in a COB(Chip On Board) mode. Light from the light emitting diode is directly diffused on the circuit board. The light from the light emitting diode generally has the light emitting angle of about 180 degrees. The lamp socket heat dissipating module absorbs and guides the heat generated in the light emitting diode. A sphere lamp cover(40) is arranged on the light emitting diode of the lamp cover heat dissipating module.;COPYRIGHT KIPO 2012
