Motor vehicle light controlling device
First Claim
1. A light controlling device for a motor vehicle, comprising an operating switch and electronic apparatus assigned to the operating switch for supplying current to a multiplicity of lamps of an operating light system and having for each lamp function at least one controlled switching component for clock-controlled supplying of current to an assigned lamp, wherein the apparatus includes a light switch module and a rear lamp module, clock controlling apparatus being distributed over the rear lamp module, and both modules being connected to each other via a maximum of three line conductors in addition to a frame terminal, the light switch module being arranged in a dashboard region and the rear lamp module being installed in a rear region adjacent the rear lights, and the lamp currents being clock-controlled such that the luminosity of certain lights can be lowered as required and/or the on-board system voltage can be increased temporarily without the luminosity changing significantly as a result.

Abstract
A motor vehicle light controlling device includes an operating switch and electronics assigned to the operating switch for supplying current to a multiplicity of lamps of the operating light system. At least one controlled switching component provides a clock-controlled supply of current to the assigned lamp circuit. The device is divided into a light switch module and a rear lamp module. A clock control provided, distributed over both modules, in order to influence the lamp currents of the vehicle operating lights. That is, in order to lower the luminosity of certain lights when required, and to be able to increase the on-board system voltage temporarily without the luminosity or lamp power changing as a result. The latter is of interest, for example, for the brief driving of electrical heating elements or servomotors to achieve an advantageously high utilization of conductor material. Lamps for driving light can be dimmed when the vehicles stationary to a luminosity corresponding to the customary parking light. Or, in the event of failure of a lamp or of a circuit for driving light, the corresponding headlamp can be supplied with current clock-controlled for lower light power for an emergency driving light function.
