<P>PROBLEM TO BE SOLVED: To radiate light to the outside with fixed intensity by individually adjusting the intensity of light from each LED, and to perform miniaturization. <P>SOLUTION: An emitter 1 has a red LED 10 for radiating red light, a green LED 11 for radiating green light, and a blue LED 12 for radiating blue light, thus generating white light. In a base member 2, respective LEDs 10-12 are packaged. Each of respective light detectors 60-62 opposes mutually different LEDs 10-12 and is provided in the base member 2, thus detecting light radiated from the opposing LEDs 10-12. A control unit 7 controls current supplied to respective LEDs 10-12, so that the intensity of color light detected by respective light detectors 60-62 becomes the intensity of predetermined color light. <P>COPYRIGHT: (C)2008,JPO&INPIT |
