Claims (1)

[Scope of Claim for Utility Model Registration] (1) A reflector equipped with a bulb as a light source, a projection lens provided in the front position of the reflector, and a clear cut forming device provided at the rear focal point of the projection lens. In a reflector movable automobile headlamp, the light projecting unit integrated with the shade is supported so as to be tiltable vertically and horizontally within the lamp body. A small hole for transmission is formed, and the light passing through this small hole is guided as a spot light to a predetermined area on the periphery of the front lens via the projection lens, and the irradiation angle of the headlamp is adjusted to the spot light forming position of the front lens. An automobile headlamp characterized by having a reference point for adjustment. (2) A projection system that integrates a reflector equipped with a light source bulb, a projection lens provided in front of the reflector, and a shade for forming a clear cut provided at the rear focal point of the projection lens. In a reflector movable automobile headlamp in which a light section unit is supported so as to be tiltable vertically and horizontally within a lamp body, a small hole for transmitting light is formed at a predetermined position of the shade for forming a clear cut. The light passing through this small hole is guided as a spot light to a predetermined area on the periphery of the front lens via a separately provided optical member and the projection lens, and the irradiation angle of the head lamp is adjusted to the spot light forming position of the front lens. An automobile headlamp characterized by having a reference point attached thereto. (3) A projection system that integrates a reflector equipped with a light source bulb, a projection lens provided in front of the reflector, and a shade for forming a clear cut provided at the rear focal point of the projection lens. In a reflector movable automobile headlamp in which a light section unit is supported so as to be tiltable vertically and horizontally within a lamp body, a small hole for transmitting light is formed at a predetermined position of the shade for forming a clear cut. The light passing through this small hole is guided as a spot light to a predetermined area on the periphery of the front lens via a separately provided light guiding member, and a reference for adjusting the irradiation angle of the headlamp is placed at the spot light forming position of the front lens. An automobile headlamp characterized by having dots attached.
