Abstract: A luminous module includes a light source and an optical part for shaping the light rays emitted by the light source. The light source is a semiconductor source that includes a plurality of electroluminescent units of submillimeter dimensions, and at least one positioning outgrowth configured to participate in the positioning of the light source on an optical part. The light source is positioned with respect to the optical part by interaction of the at least one positioning outgrowth with a corresponding receiving orifice formed in the optical part.

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 cooling member for a lighting and/or signaling device for a motor vehicle, the member comprising a base configured to support a light source of the device, and at least one heat dissipating device in thermal conduction connection with the base, the heat dissipating device comprising a plurality of heat dissipation fins, the base having large faces linked by a wafer, each of the fins extending from one of the large faces, the base extending in shape such that junction areas of at least two of the fins with the base extend in different planes.

Abstract: A vehicle lighting device component that comprises a component body having at least one fastening means for fastening the component. The device has a bearing element secured to the body that is separate from the fastening means, and comprises a bearing surface. The vehicle lighting device component is intended to bear against the bearing surface when it is fastened. The bearing element and the body are designed such that the bearing surface is able to move with respect to the body. The device also comprises a damper that is able to damp a movement of the body to move it toward or away from the bearing surface.

Abstract: A light device 1 for a motor vehicle comprising: at least one first aperture for air, and a first plug for the at least one first aperture, the first plug being movable between a ‘closed’ position and an ‘open’ position of the first aperture. The light device thus makes it possible to achieve: efficient ventilation, when the plug is in the open position, particularly when the vehicle is moving, and relative obstruction to the ingress of dust and liquids, when the plug is in the closed position, particularly when the vehicle is stationary.
