Abstract: The present invention relates to a vehicle turn indicator luminous device (1) comprising: an optical element (10) having a controlled caustic generator surface (12) so as to propagate a pattern over a usable range, a mounting part (2) on which is intended to be mounted a beam generator (3) of rays incident on said generator surface, the optical element being such that the propagated pattern is projected onto a target surface, visible from the exterior of the lighting device and situated in the usable range.

Abstract: A device for controlling a matrix of light sources of a luminous module for lighting the interior of the passenger compartment of a motor vehicle. The device includes a central unit configured to receive an instruction to activate one among a plurality of preset functions for lighting the passenger compartment, and functionally connected to a plurality of command devices, each of which is configured to command the activation of a group of light sources of the matrix. The central unit is configured to select a plurality of light sources of the matrix to activate to produce the lighting function, and to transmit instructions to the command devices in order to command the activation of the selected light sources.
