Abstract
An illumination apparatus, which controls a supply power supplied to a lamp according to an accumulated interval of on-time and a light control signal, is configured in which a maximum supply power supplied to the lamp according to the accumulated interval of on-time is supplied to the lamp when the supply power to the lamp corresponding to the light control signal is above the maximum supply power to the lamp according to the accumulated interval of on-time at a point when the illumination apparatus is turned on or the lamp starts lighting. When the light control signal is operated so as to exceed a level of the maximum supply power to the lamp according to the accumulated interval of on-time or the light control signal varies more than a prescribed level, the supply power is shifted to an adjustable condition so as to be higher than the maximum supply power to the lamp according to the accumulated interval of on-time.
