<p>A lighting device (1) for a vehicle, and in particular a motor vehicle headlamp, comprising a light source (3) for emitting light and a reflector (2) for focusing the light emitted by the light source (3), there being formed, at the rear end of the reflector (2), an opening to receive at least a part (18) of the light source, and a reflector neck (21) that surrounds the opening and to which the light source (3) is fastened in a defined position relative to a reflective surface of the reflector (2). The lighting device is characterized in that a plurality of locking members (23, 24, 24′) are formed on the reflector (2), which locking members (23, 24, 24′), in the course of a rotary movement of the light source (3) about the optical axis (10) of the reflector (2) or about an axis parallel thereto when the light source (3) has been at least partly inserted in the reflector neck (21) in the direction of the optical axis (10), engage in corresponding perforations (17) formed in the light source (3), at least one of the locking members (23, 24, 24′) co-operating with at least one of the perforations (17) in the course of the rotary movement in such a way, and causing forced guidance of the light source (3) in such a way, that the light source (3) is held in a defined position relative to the reflector (2) in the axial direction.</p> |
