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.
A lighting device for a motor vehicle headlamp, comprising
A lighting device as claimed in claim 14, wherein the perforations each follow a path that curves in an arc and is obliquely aligned to the circumferential direction, the distance between the perforations and the center of that part of the light source that is received by the reflector neck decreasing in the direction of the rotary movement.
A light source of a lighting device for a vehicle, and in particular a motor vehicle, having a part that can be received by a neck integrally formed with a reflector of the lighting device, wherein the light source has at least one perforation to receive at least one correspondingly formed locking member on the reflector neck, at least one of the perforations being so matched in arrangement and/or configuration to the arrangement and/or configuration of at least one of the locking members that, on being received in the reflector neck, the light source is forcibly guided, during a rotary movement of the said light source that follows about the optical axis (10) of the reflector or about an axis parallel thereto, in such a way that the light source is held in a defined position in the axial direction relative to the reflector.
