An infrared light irradiating lamp for a vehicle includes a projection lens disposed on an optical axis extending in a longitudinal direction of the vehicle, a light source bulb disposed behind a rear focal point of the projection lens, a reflector for reflecting light emitted from the light source bulb in a forward direction close to the optical axis by setting the light source bulb as a first focal point of the reflector, a filter driving unit disposed between the projection lens and the light source bulb, the filter driving unit having a movable shaft to be driven in a vertical direction, a bracket having a tip portion and a base end, the tip portion holding an infrared light transmitting filter, and a rotating shaft disposed between the movable shaft to the base end of the bracket for linking the movable shaft to the base end.

Infrared light irradiating lamp for vehicle

A projector type vehicle headlamp comprises a reflector, a light source, a projection lens, a rotational shade to shield part of light reflected on the reflector so as to be directed towards the projection lens and a motor for driving the rotational shade based on a light distribution switching over operation. In the headlamp, a high beam corresponding light shielding plate and an another beam corresponding light shielding plates are disposed on the rotational shade on both sides of a low beam corresponding light shielding plate, so that the light distributions are attempted to be switched over speedily between the low beam and the another beams and the generation of glare is attempted to be prevented.
