PROBLEM TO BE SOLVED: To attain downsizing and improvement in operability of a controller for illumination light source used for adjustment of an amount of light and color temperature of irradiation light.SOLUTION: A controller 1 is provided with a dimming dial 6 used for adjustment of an amount of light of irradiation light from an illumination light source and a color adjusting dial 7 used for adjustment of color temperature of the irradiation light. These dimming dial 6 and color adjusting dial 7 are respectively constituted of disc-shape knobs capable of turning, and are arranged mutually superimposed. The amount of light is adjusted by turning of the dimming dial 6, and the color temperature is adjusted by turning of the color adjusting dial 7. Since the dimming dial 6 and the color adjusting dial 7 are mutually superimposed, the controller 1 can be downsized, and further, since both the dials 6, 7 are turned to adjust the amount of light and the color temperature, operability is good. |
