DEVICE FOR EMITTING WHITE-COLOR LIGHT |
摘要 |
A device for emitting white-color light comprises: a light emitting diode including: an LED chip comprising a gallium nitride compound semiconductor containing indium and being capable of emitting a blue color light, and a phosphor capable of absorbing a part of the blue color light and emitting a light having longer wavelength than the blue color light, the blue color light and the light from the phosphor being mixed to make the white-color; a control unit for converting an input to pulse signals; and a driver receiving the pulse signals from the control unit to drive the LED chip, wherein the brightness of the white-color light from the light emitting diode is controlled by a width of the pulse signals.
