摘要： A technique for forming a white light LED is disclosed. In one embodiment, the LED emits blue light. A first phosphor for producing red, yellow, yellow-green, or green light is formed to conformably coat the LED die. One suitable deposition technique is electrophoretic deposition (EPD). Over the resulting LED structure is deposited another phosphor (to add the remaining color component) in a binder (e.g., silicone) for encapsulating the die. The blue LED light combines with the two phosphor colors to create white light. Since the two different deposition techniques are independent and easily controllable, the resulting white light temperature is highly controllable and the color emission is substantially uniform.
