<P>PROBLEM TO BE SOLVED: To provide a lighting apparatus in which LEDs having different color temperatures are effectively arranged therein, and which performs a lighting control and a color matching by a lighting method which utilizes each characteristics. <P>SOLUTION: A lightning apparatus 10 comprises: a remote control light receiving part 20; a driving part 30; and a light source unit 40. In the light source unit 40, a plurality of first LEDs 41 and a plurality of second LEDs 42 acting as light sources, are mounted on a substrate 43, and they are configured as one package. The first LEDs 41 have for example, a color temperature of from 5000k to 10000k, and the second LEDs 42 having a color temperature being different from that of the first LEDs 41, have for example, the color temperature of from 2000k to 3000k. The color temperature changes by changing the lightning number of the first LEDs 41 and the second LEDs 42, thereby shifting values of maximum light flux of each of color temperatures to a low color temperature side to enable the lightning control of the lightning apparatus 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
