Embodiment Construction

[0027] figure 1 It is a perspective view of a vehicle headlamp 1 and a lamp 2 separated therefrom before installation. Without limiting the invention, only the parts of the vehicle headlamp 1 and the lamp 2 which are necessary for understanding the invention are explained below.

[0028] figure 1 The vehicle headlamp 1 shown in includes a reflector adapter 3 on which a lamp holder 4 is placed. The lamp holder 4 can be an integral part of the reflector adapter 3 or a separate part.

[0029] The lamp 2 generally comprises a light source 6 and an actuator 7 forming a connection assembly.

[0030] An opening 5 through which the light source 6 of the lamp 2 passes is formed in the reflector fitting 3 (and the reflector not shown in the figure) and the lamp socket 4 . After installation (see figure 2 ), the light source 6 of the lamp 2 is derived from the opening 5, and the starter 7 passes through the lamp holder 11 (refer to image 3 ) on the lamp holder 4. The reference p...

Abstract

The lamp holder (4) comprises coding elements (8a,8b) for providing lamp type. The coding elements are provided with a pin shape, where the lamp holder is provided under the coding element material degradation (14) which is provided as a reduced wall thickness or as a recess or as a bore.

Description

technical field [0001] The invention relates to a lamp holder for a vehicle headlamp comprising a coding element for unambiguously defining the type of lamp used. Background technique [0002] When installing a lamp to the lamp socket (socket) of a vehicle's headlamp, it is necessary to ensure that the correct lamp is installed. This depends inter alia on compatibility between lamp and reflector. Using the wrong light source can sometimes violate legal regulations or cause damage to components, for example due to overheating. [0003] In many cases it is ensured that the correct type of lamp is installed by attaching a coding device to the socket which cooperates with a corresponding device placed on the lamp. These coding elements comprise, for example, lugs that mate with corresponding holes in the lamp. By arranging the pins according to the type of lamp required, it is ensured that the correct lamp is installed. [0004] Many reflectors are very specific designed for...
