Claims

[Scope of utility model registration request]

In a headlamp in which a lens is installed near the front opening of a reflector having a reflective surface in the shape of a paraboloid of revolution, and a light source bulb is provided near the focal point of the paraboloid of revolution, the reflector is located at the center of the reflector. A paraboloid of revolution reflective surface is provided in the part, and a pair of planar reflective surfaces that taper toward the front are provided on the periphery of the paraboloid of revolution, and the pair of planar reflective surfaces are A pair of planar secondary reflecting mirrors are installed facing each other and substantially parallel to each other, and the pair of secondary reflecting surfaces are spaced apart from each other, so that the direct light emitted from the light source bulb is reflected by the pair of secondary reflecting mirrors. A headlamp characterized in that it is configured to shine directly onto a lens through a space between surfaces.
