ABSTRACT:
The vehicular headlamp of the projection type in which a projection unit is installed within a lamp body, the projection unit including an elliptic reflector, a discharge lamp as a light source disposed at a first focal position of the elliptic reflector, an ultraviolet-rays shield glove for covering the discharge lamp, and a projection lens disposed at a forward location of the elliptic reflector, the projection lens collimating and projecting forward the light reflected from the elliptic reflector. The headlamp is improved in that the ultraviolet-ray shield glove is a tubular member which is opened at the fore end and includes a inner lens, disposed between the discharge lamp and the projection lens, for intercepting the ultraviolet rays.
