Abstract

The present invention proposes a light emitting module including a flexible printed circuit board. The connection to ground of the electronic circuit housed by the printed circuit board is produced without adding fixed parts dedicated to this function. Compared to the known prior art, the invention allows the production of lighting modules comprising fewer component parts and occupying a smaller volume.

Description

technical field [0001] The invention relates to the field of lighting and luminous signaling, in particular in motor vehicles. Background technique [0002] In the field of lighting and luminous signaling for motor vehicles, the use of light sources comprising light-emitting semiconductor elements, such as light-emitting diodes (LEDs), has become more and more frequent. The LED element emits light when a voltage having a value at least equal to a threshold value called a turn-on voltage is applied to these terminals. [0003] As is known, one or more LEDs of a lighting module for a motor vehicle are powered with a supply control device comprising a converter circuit. The supply control device is configured to convert a current of a first magnitude, eg delivered by a current source of the motor vehicle, such as a battery, into a load current of a second magnitude different from the first magnitude. As is known, the electronic circuit forming the supply control means and the...
