<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. A base member 2 comprises: an LED package 22 where respective LEDs 10-12 are packaged; and walls 23-26 provided around a region where respective LEDs 10-12 are packaged in the LED package 22. Each of a plurality of light detectors 50-55 is provided at the walls 23-26, thus detecting the intensity of light radiated from mutually different LEDs 10-12. A control unit 6 controls current supplied to respective LEDs 10-12 so that the intensity of color light detected by respective light detectors 50-55 becomes the intensity of predetermined color light. <P>COPYRIGHT: (C)2008,JPO&INPIT |
