  • Patent number: 9822943
    Abstract: A light deflecting device selectively reflects an incident light to a projection optical system. An irradiation optical system irradiates light to a reflective part of the light deflecting device. The light deflecting device has at least some region in the reflective part, a position of which is switchable between a first reflection position where the light irradiated by the irradiation optical system is reflected toward the projection optical system so as to be effectively used as a portion of a desired light distribution pattern, and a second reflection position where the light irradiated by the irradiation optical system is reflected so as not to be effectively used. The irradiation optical system is disposed at a position shifted to a side which a front face of the reflective part in the first reflection position faces, with reference to a vertical plane including an optical axis of the projection optical system.
