Embodiment Construction

[0013] figure 1 A schematic diagram of a motor vehicle 1 according to the invention is shown. The motor vehicle comprises two headlights 2, in each of which is integrated (integrated) a luminous device 3, which is assigned to the "directional indicators" and "daytime running lights / position lights". "Lamp species. Since both lamp types are produced with light-emitting diodes, the two luminaires 3 are assigned a drive 4 which can be mounted directly on the luminaire 3 , for example. The driver 4 supplies the required operating voltage for operating the light-emitting diodes of the luminous device 3 . The operation of the lighting device is controlled by a lighting controller 5 .

[0014] figure 2 The structure of the lighting device 3 and the drive device 4 is shown in more detail. It is clear that the luminous device 3 has two light-emitting diode modules 6 , 7 , wherein the light-emitting diode module 6 has a light-emitting diode 8 for the daytime running light / position...

Abstract

An actuation apparatus (4) for a lighting device (3) of a motor vehicle (1), which comprises at least one LED which is assigned to a travel direction indicator and at least one LED which is assigned to another type of light, in particular a driving light and / or a position light, and a common optical arrangement (10) for the types of light, wherein the actuation apparatus (4) comprises a single direct-voltage transformer (11) which is used both for the LEDs of the travel direction indicator and for the LEDs of the further type of light, as well as a control unit (12) for actuating the direct-voltage transformer (11) as a function of a control signal.

Description

technical field [0001] The invention relates to a drive for a motor vehicle luminaire having at least one light-emitting diode (LED) associated with a direction indicator / turn signal, at least one associated with another type of light, in particular daytime Driving lights and / or position lights (side lights / parking lights, Positionslicht) - LEDs and common optics / outer structure (Optikanordnung) for the individual light types. Background technique [0002] The lighting of modern cars tends to integrate different lights. Accordingly, there is a tendency to provide a common appearance for daytime running lights and / or position lights and direction indicators (flashing lights), so that these types of lights—that is, direction indicators and daytime running lights and / or position lights (Parking Lights) - Appears in the same location to an outside observer. This is possible because the daytime running lights or position lights are not used at the same time as the direction ind...
