Abstract

To block an air flow turning at a terminal end section of an extension from between the extension and a lamp body in a rear section of a lamp chamber end section to blow on a cover, and prevent formation of dew on the cover in the rear section of the lamp chamber end section. A vehicular headlamp (100) includes two lamp units (25) and (27) as projector-type lamp units and an extension (31) covering gaps among a lamp body (21) and the lamp units (25) and (27). A lamp chamber (22) has a lamp chamber end section (55) extending laterally with respect to the projector-type lamp unit (25) and rearward of a vehicle, and an air flow blocking section (57) that blocks air flowing in a rear section (55b) of the lamp chamber end section (55) from the lamp units (25) and (27) is provided between the extension (31) and the lamp body (21) in a front section (55a) of the lamp chamber end section (55).

Description

technical field [0001] The present invention relates to a vehicle headlamp, and more particularly to a vehicle headlamp in which a lamp house incorporating a projection lamp unit has an end portion of the lamp house extending toward the rear of the vehicle. Background technique [0002] A structure in which a projector lamp unit is built into a vehicle headlamp is known. A projection lamp unit generally includes a light source, a projection lens, and a reflector that reflects light from the light source toward the projection lens and forward. In the vehicle headlamp, a lamp housing is attached to the front of the lamp body to form a closed lamp chamber, and a projection lamp unit is built in the lamp chamber. [0003] In addition, in the vehicle headlamp with built-in projection lamp unit, there is also a built-in extension part, which is used to cover and hide the part of the projection lamp unit except the projection lens, and the gap between the lamp body and the project...
