A light module () for a lighting device () of a motor vehicle includes a plurality of semiconductor light sources () in serial connection with each other. A circuit arrangement () is assigned to and connected in parallel with at least one of the light sources (), includes a plurality of detectors () for detection of a malfunction of the light source (), and is adapted for bypassing the light source () in case of a malfunction of the light source (). A lighting device () of a motor vehicle includes at least one light module () for generation of a predefined light distribution.

Lighting device of a motor vehicle

A combination () of a power-supply control device () and at least one light-control device () of a motor vehicle operates at least one semiconductor light source (). The control device () supplies the light-control device () with power via a supply line () connected to a first connection pin () of the control device (), monitors current flowing through connection pins of the control device (), and makes use of diagnoses thereof. The light-control device () is connected to an additional connection pin () of the control device () via an error line () and checks function of the connected semiconductor light source () and, in the case of a malfunction, triggers a current flow in the error line (). The control device () reacts to the triggered current flow with generation of an error message.

Internal power supply control device having at least one lighting control device for a motor vehicle

A light module for a vehicle lighting device comprises a semiconductor light source mounted on a carrier element designed. on/including a first printed-circuit board. A control module is electrically connected to and structurally spaced from the light source and designed on/includes a second printed-circuit board and includes an electric circuit constructed upon the second board and a connection element adapted w be connected to a higher-level controller and/or vehicle power supply. The control module is an electronic component of the light source such that a cable does not connect the control module and light source to each other. A highly thermally conductive carrier module is arranged between the light source and control module and directly attached to the carrier element, second printed-circuit board, and electric circuit. An electrical connection is located on the carrier module between the fight source or carrier element and electric circuit or second printed-circuit board.

A controller controls an illumination device of a motor vehicle including at least one light source. The controller includes at least one first stage that provides electric energy for supplying power to the illumination device. At least one second stage forwards the electric energy to the light source. The first stage includes intelligence for controlling the illuminating device, a first supplier for supplying the illumination device with control signals, a generator for generating a constant intermediate voltage, and a second supplier for supplying the second stage with the intermediate voltage. The second stage includes a converter for conversion of the intermediate voltage into a supply voltage suitable for supplying the power to the light source, a third supplier for supplying the light source with the supply voltage, and a mechanism for controlling the light source in dependency on the control signals. Also, an illumination device for a motor vehicle includes the controller.
