Abstract: A method for correcting a first light pattern provided by a lighting device with a matrix of light sources. The method includes steps of providing some resolution data of the light sources, simulating a test map of the light pattern using the resolution data, and simulating distortion maps of the test map. Each distortion map is associated to a distortion factor. Also included is obtaining a real distorted light pattern, comparing the real distorted light pattern with the distortion maps, finding a distortion map which is the most similar to the real distorted map and applying a correction factor to correct the real distorted light pattern, thus obtaining a corrected light pattern. The correction factor is related to the distortion factor of the distortion map which is the most similar to the real distorted map.

Abstract: The invention relates to a light module, in particular for a motor vehicle, comprising a light source capable of emitting light rays; a collector with a reflective surface configured to collect and reflect the light rays emitted by the light source into a light beam along an optical axis of the module; an optical system configured to project the light beam. The collector is configured so that a portion of the light rays of the light beam are parallel to the optical axis or have an angle of inclination α smaller than or equal to 25° in a vertical plane with respect to said axis; and the optical system is configured to form an image of the reflective surface of the collector. The invention also relates to a light device comprising one or more such light modules.

Abstract: The invention relates to an electronic assembly for an automotive lighting device. The inventive electronic assembly comprises a first group of light source connections and at least one jumper where each jumper is arranged to bypass a first spare light source connection belonging to the first group of light source connections by putting its first and second terminals in electrical contact. Hence when in operation, the first spare light source connection does not receive any light source. The first group of light source connections are intended to receive light sources which are used for the same lighting function. The invention also relates to a lighting device that includes such an electronic assembly with a method that includes manufacturing such a lighting device.
