<p>PROBLEM TO BE SOLVED: To provide an illumination controller capable of achieving a color temperature and brightness, specified by a user, accurately even when the light flux of white LED and bulb color LED is different during 100% output.SOLUTION: An illumination controller includes a storage section 150 for controlling a lighting fixture having a white LED having a maximum light flux L1 during maximum output, and a bulb color LED having a maximum light flux L2 different from the maximum light flux L1 during maximum output, and storing the maximum light flux L1, the maximum light flux L2, the color temperature K1 of the white LED, and the color temperature K2 of the bulb color LED, an input section 110 for inputting the target color temperature K3 of a lighting fixture 60, and the target output D3 of a lighting fixture 60, a calculation section 120 for calculating the dimming rate D1 of the white LED and the dimming rate D2 of the bulb color LED based on the ratio of the maximum light flux L1 and maximum light flux L2, the target color temperature K3, the target output D3, the color temperature K1, and the color temperature K2, and a control section 130 for dimming the lighting fixture 60 based on the dimming rate D1 and D2 thus calculated.</p> |
