Patent ID: 7080909

Claim:
An illumination apparatus which directs light from a light source to an illuminated area, comprising: a plurality of light emitters as the light source; a lighting unit configured to cause the light emitters to emit light so that the intensities of light emitted by the light emitters can be adjusted; an optical system configured to direct light emitted by the light emitters to the illuminated area; a storing unit configured to store an adjusting amount of the emitted light for changing the intensities of light emitted together with time; and a lighting control unit configured to control the lighting unit based on the adjusting amount of the emitted light stored in the storing unit so that the respective light emitters carry out pulsed emission at different timings, wherein the adjusting amount of the emitted light stored in the storing unit is an adjusting amount so as to change the intensities of light in a pulsed emission period of the respective light emitters.
