Abstract:
The invention notably relates to a light-emitting module of a terrestrial vehicle having at least one semiconductor light source including a mostly semiconductor material substrate, the substrate having a first face and a second face. The light source further includes electroluminescent elements with submillimeter dimensions extending from the first face of the substrate, and at least one heatsink cooperating with the second face of the substrate to evacuate the heat produced by the light source. The invention therefore offers an improved light-emitting module for terrestrial vehicles.

Abstract:
A lighting device for an automotive vehicle comprising at least two semiconductor light sources that can be selectively activated and at least one optic for shaping at least a portion of the light rays emitted by either or both of the light sources with the aim of generating at least two lighting and/or signaling functions. The device is configured so that a first function requires the activation of the first semiconductor light source and a second function requires the activation of the second semiconductor light source. At least one of the light sources is a semiconductor light-source comprising a light-emitting rods.
Abstract:
A lighting and/or signaling device and method comprising an opaque element that can move between at least two positions, one of the positions interposing the opaque element between the main light source and the optical focusing device, in which the opaque element is arranged so that when it is interposed between the main light source and the optical focusing device it prevents rays originating from outside the lighting and/or signaling device from being focused, especially in a line or spot, by the optical focusing device, in order to prevent degradation of the lighting and/or signaling device.

Abstract:
A light module, comprising: a support comprising at least one first surface called a separating surface and at least one organic light-emitting diode comprising a first light-emitting part, a connecting part or means for attaching the diode to the support and an electrical connector or means for electrically 10 connecting the diode. The means for attaching the diode and the electrical connector or means for electrically connecting the diode are borne by a part of this diode, called a connecting part. Additionally, the separating surface of the support delimits a light-scattering area into which the first light-emitting part of the diode extends, and separates this light-scattering area from a 15 masked area, into which connecting part of the diode extends, such that the connecting part is occulted by the separating surface of the support.
