摘要： 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.

摘要： A light module for a motor vehicle, including a first electrical assembly on a first carrier, which harbours a plurality of branches that are connected in parallel, each branch including light sources, preferably light-emitting diodes. The module includes a second carrier which includes a control unit for controlling the supply of electrical power to the light sources, the control unit including a feedback loop from a reference branch. The light module allows the number of connections between the two carriers of the assembly to be decreased and reliability thereof to be increased.

摘要： A light-emitting module for a motor vehicle. The light-emitting module includes a substrate including a curved main section, light-emitting elements arranged on a face of the substrate and configured to generate light rays, a curved screen arranged facing the face of the substrate and away from the face, an area of the screen being suitable for being illuminated by the light rays emitted by the light-emitting elements, the screen having scattering properties with respect to the light emitted by the light-emitting elements, each light-emitting element being arranged on the substrate in a given zone, each light-emitting element furthermore being arranged to emit the corresponding light rays in a main emission direction that is angularly offset from a local direction that is normal to the substrate in the given zone.

摘要： A method of managing the power dissipated by an electroluminescence light source including electroluminescent rods having submillimeter dimensions protruding from a substrate and split into a plurality of identical groups. By using the measures of the invention, it becomes possible to manage the dissipation of power from the light source when faced with instantaneous variations in the strength of the electric current that powers the latter.

摘要： A light emission module, in particular for a motor vehicle. The module includes a substrate comprising a curved main portion extending in a longitudinal direction. A plurality of electroluminescent elements is arranged on the substrate and configured to emit light rays when supplied with electrical energy. The electroluminescent elements are distributed along tje longitudinal direction, and a control assembly suitable for regulating the electrical energy supplied to the electroluminescent elements. The control assembly has a mode of operation in which the control assembly is configured to supply the electroluminescent elements with respective electrical energies and/or powers determined at least as a function of respective main directions of light emission of the electroluminescent elements to obtain at least two maximum light intensities emitted by the electroluminescent elements in the corresponding main direction of emission which are different along the longitudinal direction of the substrate.
