Problems solved by technology
[0008] In general, in the lighting devices known from the prior art with a gas discharge lamp and a separate control unit, it is disadvantageous that, in the motor vehicle, a control must be provided for being arranged outside or on the housing of the lighting device. Additional installation space for the
Furthermore, the assembly of the known lighting device becomes relatively complex, since in addition to the assembly of the light module with the gas discharge lamp and the igniter, the controller must additionally be arranged in a separate work step outside the housing and in contact with the igniter
[0009] This results in a relatively time-consuming and also expensive assembly
The cost of the shielded wires between the igniter and the controller is another issue

Embodiment Construction
[0037] exist figure 2 A lighting device known from the prior art in the form of a motor vehicle headlight is generally designated with the reference numeral 100 .
[0038] The lighting device 100 comprises a housing 101, which is preferably made of plastic. In the light exit direction 102 , the housing 101 has a light exit opening 103 which is closed by a light-transmissive protective cover 104 . The protective cover 104 is preferably formed as a transparent sheet. However, it is also conceivable that the protective cover 104 has an optical effect profile (not shown), for example in the form of a lens, prism or the like, in particular for controlling the passing light.
[0039] A light module 105 having a light source 106 and a reflector 107 is arranged inside the housing 101 . The light module 105 can be mounted in one or more support frames and is mounted rotatably in the horizontal and / or vertical direction in the headlight housing 101 . In the exemplary embodiment sho...

The invention relates to a lighting device for a motor vehicle. Said lighting device comprises a gas discharge lamp (1; 96) for emitting light, a starting device for providing a starting voltage for starting the gas discharge lamp (1; 96) and a control device for providing an input voltage for the starting device and an operating voltage for operation of the gas discharge lamp (1; 96). The control device is an integral part of the starting device. In order to come to grips with the problems associated with space and temperature with such lighting devices, the invention proposes that the combined starting and control device (5; 80) has a plug element (6) for connecting a vehicle power supply system voltage (7), the plug element (6) being in the form of a printed circuit board plug, which is formed by conductor tracks (21; 23) guided at an edge of a printed circuit board (20) of the starting and control device (5; 80).
Description
technical field [0001] The invention relates to a lighting device for a motor vehicle, which comprises a gas discharge lamp, an igniter and a controller or ballast. Gas discharge lamps emit light visible to the naked eye. The igniter provides an ignition voltage for igniting the gas discharge lamp. The controller is used to provide an input voltage for the igniter and an operating voltage for operation of the gas discharge lamp. The voltage is generated by the controller from the on-board electrical system voltage of the motor vehicle. An integral part of the lighter. Background technique [0002] Such a lighting device is known from DE 35 19 611 A1. In this case, the combined ignition and control unit is arranged on the rear side of the reflector. Via the opening in the reflector, the gas discharge lamp arranged in the interior of the reflector is in contact with the ignition control and is fixed at least indirectly on the ignition control. Furthermore, the space requ...
