Claims

[Scope of utility model registration request]

A reflector having a reflective surface on its inner surface, and the reflector
In the vehicle headlamp, the reflector includes a synthetic resin lens located in front of the reflector, and at least one filament having a length along the optical axis of the reflector, the reflector having a substantially paraboloid of revolution shape. a second reflecting surface located above the first reflecting surface and having a substantially paraboloid of rotation shape;
The focal point of the second reflective surface is located in front of the focal point of the first reflective surface, and is tilted downward around the self focal point of the second reflective surface, and the filament is located in front of the focal point of the first reflective surface. A vehicle headlamp characterized by being located between the focal points of the second reflective surface.
