Patent ID: 8104940

Claim:
A vehicle headlamp comprising: a projection lens disposed on an optical axis extending in a front-rear direction of a vehicle; a halogen bulb disposed behind a rear focal point of the projection lens and below the optical axis; a main reflector which forwardly reflects a first part of direct light from the halogen bulb to converge the first part of the light toward the optical axis, wherein the halogen bulb is fixedly inserted in the main reflector in a sidewise direction with respect to the optical axis; a movable shade disposed between the projection lens and the halogen bulb to shield a portion of the first part of the light reflected by the main reflector and a second part of the direct light from the halogen bulb to form a cutoff line of a light distribution pattern; an actuator which moves the movable shade between a shielding position, at which an upper edge of the movable shade is located in a vicinity of the rear focal point of the projection lens, and a lessened shielding position, at which an amount of the first part of the light shielded by the movable shade is less than an amount of the first part of the light shielded when the movable shade is at the shielding position; and an auxiliary reflector disposed below the optical axis to forwardly and diffusely reflect a third part of the direct light from the halogen bulb such that the third part of the light passes below the projection lens.
