PROBLEM TO BE SOLVED: To provide an LED illumination system which can change a color temperature depending on user's preference with a simple operation.SOLUTION: An LED illumination system comprises: a lighting fixture L1 with two types or more LEDs of different color temperatures serving as light sources mounted thereon; switch means (constant current switching parts 15, 16) for switching light emission of the LEDs of different color temperatures configuring the light sources, for each type of the color temperatures; control means (a control unit 12) for performing a switch control; a pull-less switch 30 for giving a control instruction; determination means (a microcomputer M) for determining whether there is a control instruction; and storage means for storing information on the color temperature. The control means performs the switch control by the switch means in accordance with a control instruction when the determination means determines that there was a next control instruction by the pull-less switch, and performs the switch control by the switch means on the basis of the information on the color temperature stored in the storage means when the determination means determines that there was no next control instruction by the pull-less switch. |
