PROBLEM TO BE SOLVED: To obtain a color temperature variable LED light source module, capable of arbitrarily changing a correlation color temperature by color mixing LEDs having different emission colors, by changing the luminous flux ratio using a simple constitution and being substantially equal to the color temperature locus of a perfect radiator or the locus of CIE daylight. SOLUTION: The color temperature variable LED light source module comprises a white LED 1 for emitting white light, a green LED 2 for emitting green light, a red LED 3 for emitting red light, and a diffusing unit 5 for light mixing the lights radiated from the LED 1, the LED 2 and the LED 3. |
