Abstract :
An experimental feasibility study of novel white light LED structure with omni-directional reflectors has been demonstrated. A comparison of the fluorescence with or without omni-directional reflector coating shows that the fluorescence intensity from the phosphor grain layer has been enhanced significantly when with omni-directional reflector coating.
