Abstract
PURPOSE:A dimmer apparatus for optimizing the intensity of illumination of an irradiated face by automatically controlling the output of a discharge lamp corresponding to the field illumination intensity of brightness in a field of illumination where the illumination intensity of an irradiated face is closely related to the outside illumination as in the case of illumination inside a tunnel, for example.
