Claims

[Scope of utility model registration request]

- a concave reflector that has a light bulb at its focal position and reflects the light from the light bulb; a long-range reflector that is formed in most of the concave reflector and illuminates a long-distance road surface; and a long-range reflector that is formed in a part of the concave reflector; A headlamp device comprising: a short-distance reflector that illuminates a road surface at a short distance; and a lens provided in front of the concave reflector and provided with a diffusion portion that diffuses reflected light from the short-distance reflector.
