摘要： A method for operating an automotive lighting device including at least one solid-state light source. The method includes defining a color allowance condition, feeding the light source with a current value which produces a luminous flux value higher than a minimum luminous flux threshold value, measuring the temperature in the light source, checking whether the output color satisfies the allowance condition and increasing or decreasing the current value, always keeping the current such as it produces an acceptable color. With the checking includes perform a pulse width modulation of the current value to keep an average value of the current which produces a luminous flux value higher than the minimum luminous flux threshold value. The invention also provides an automotive lighting device comprising a control element to carry out the steps of this method.

摘要： The invention provides a method for managing image data in a motor vehicle lighting system, the lighting system including at least one lighting module intended to project light beams, the light beams being generated from data relating to the selection of at least one image, each image being respectively defined by a matrix including a plurality of horizontal or vertical rows of pixels, with each pixel having a numerical value related to a light intensity of the pixel. The method includes determining whether the pixel under analysis is considered to be a significant point of inflection of the image, so as to transmit it to at least one lighting module, so that it is able to project a resulting image.

摘要： A method for detecting an object in a road surface. The method includes defining a light pattern including dark and lighted groups of square pixels, projecting the light pattern on a road surface, acquiring an image of the projected light pattern, comparing the shape and position of some groups of square pixels in the acquired image with respect of the defined light pattern, and using the comparison to infer features of an object. The invention also provides a method for autonomous driving using this object detection and an automotive lighting device.

摘要： A lighting device for a motor vehicle includes a housing having a front lighting surface, and a substantially planar plate and at least one lighting module mounted on the plate. The plate has a general plane of extension that is horizontal when the housing is mounted in the vehicle, and has a surface referred to as a lower surface and a surface referred to as an upper surface. The plate includes a first control system which includes a first male element and is arranged to cause translation of the first male element in an axis parallel to the plate, the plate being provided with a first recess receiving the first male element. A second control system that includes a second male element and is arranged to cause translation of the second male element in an axis perpendicular to the plate, the plate being provided with a second recess on its upper or lower surface that receives the second male element. The housing thus takes up less space above the modules, which can easily be raised.
