Claims

[Claim for Utility Model Registration] A light source bulb is installed near the focal point of the concave mirror, and the light emitted from the light source bulb is reflected by the concave mirror and focused near the shade having a cut line, and the reflected light is transferred to the convex lens. In a projector-type automobile headlamp that projects horizontally by a projector, (a) the shade is constituted by a concave mirror having the cut line, and the concave reflective surface is placed on the front side of the headlamp. (b) An auxiliary light source bulb is provided near the focal point of the auxiliary reflector, and the light emitted from the auxiliary light source is directed toward the vicinity of the lower end of the convex lens by the auxiliary reflector. (c) A prism is provided at a location where the light beam reflected by the auxiliary reflector reaches near the lower end of the convex lens, and the light emitted from the auxiliary light source and reflected by the auxiliary reflector is reflected in front of the headlight. A projector-type automobile headlamp characterized by being refracted in a horizontal or downward direction.
