Patent ID: 6899435

Claim:
An illumination apparatus which illuminates a portion to be illuminated with light from a light source, comprising: a plurality of light emitting members which constitute the light source; a driving circuit configured to drive the respective light emitting members; a condenser optical system configured to condense an emitted light from the light emitting member driven by the driving circuit onto the portion to be illuminated; a light control member configured to perform at least one of change of a light path of the light from the light emitting member to illuminate the portion to be illuminated and movement of the light emitting member; a movable section configured to operate the light control member in a predetermined period; a light selection control section configured to control at least one of the movable section and driving circuit so as to select the light to illuminate the portion to be illuminated from the lights of the plurality of light emitting members, wherein the driving circuit drives the light emitting members so that several of the light emitting members among the plurality of light emitting members emit light simultaneously in at least a part of a light emitting period and wherein the condenser optical system comprises a multi emission point optical system formed of a plurality of optical systems disposed at approximately the same interval as a pitch (LP) of emission points of the light emitting members which emit light simultaneously.
