Abstract
PURPOSE:To enable proper illuminance to be secured even if temperature difference between the time of illuminance measurement and the time of actual use is large, by compensating illuminance compensation value operated on the basis of illuminance detected value so that it may meet the illuminance at the time of real use by the temperature detected value near a lamp. CONSTITUTION:A temperature sensor 10 which detects the temperature near a lamp is provided in addition to illuminance sensors 81-8n which detect the illuminace of light adjusting illuminaires. And an illuminance compensation value arithmetic unit 9a is provided for operating an illuminance compensation value at the time of actual use based on the illuminance detected value at the standard time and compensating this illuminance compensation value so that it may meet the illuminance at the time of actual use based on the temperature detected value. And it is so arranged that a light adjusting control terminal 2 generates a light adjusting control signal based on light adjusting data and the light adjusting control signal is compensated according to an illuminance compensation value which is added with temperature compensation, and added to light adjusting illuminaires 61-6n. Hereby, even if temperature difference between the time of illuminance measurement and the time of actual use is large, proper illuminance can be secured.
