Edison Opto achieves uniform white light with MAPLE uniform coating technique

Mixing luminescence phosphor with silicone and dispensing it on a blue light emitting chip is a common LED package method in producing white light. The quality of white light depends heavily on the uniformity of phosphor on the blue die. Often times, when coupling secondary lens on white LED, it will reveal yellow circling. Such yellowing greatly shadows the quality of white light.
