INCANDESCENT-LIKE-DIMMING LIGHT EMITTING DIODE |
摘要 |
Phosphor-converted light emitting diodes comprising a blue or near-UV emitting semiconductor device, a yellow-green phosphor, and a red phosphor exhibit incandescent-like dimming behavior in that the Correlated Color Temperature of a white light output decreases with reduced brightness. In one aspect, a light emitting device comprises an LEO emitting blue light, a first phosphor excited by the blue light emitted by the LED and in response emitting green or greenish-yellow light, and a second phosphor excited by the blue light emitted by the LED and in response emitting red light. |
