Claims

[Scope of utility model registration request]

It includes a filament that extends near the focal point of the paraboloid of revolution reflective surface and approximately along the central axis of the reflective surface, and a light shield that covers the front surface and approximately the lower half of the filament. The side edge of is located below the horizontal plane including the central axis so that the angle θ between the side edge and the plane including the central axis and the horizontal plane is in the range of 60° to 10°. Further, a vehicle headlamp characterized in that the θ is large at the front and small at the rear.
