  • Publication number: 20250137611
    Abstract: The invention relates to a light module including a fixed mount intended to act as a support for a light source, a projection optic that has a focal plane and is designed to project a light beam from the light rays emitted by the light source, a member for holding the projection optic. According to the invention, the holding member includes a first support element and a second support element. The second support element acts as a support for the projection optic. The first support element connects the second support element to the fixed mount. The support elements are arranged so as to position the focal plane in a location in which the light module ensures good projection image quality in spite of the thermal expansion of the projection optic.

  • Patent number: 12289809
    Abstract: An automotive lighting device and 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 a luminous flux value higher than the minimum luminous flux threshold value and producing a color which satisfies the allowance condition.

  • Publication number: 20250081303
    Abstract: The invention proposes a luminous device involving a converter intended to supply power to a pixelated light source controlled by electric current. The device makes it possible to reduce power losses and to reduce the risk of the elementary light sources of the pixelated light source overheating. By using a control loop and measuring means which make it possible to directly or indirectly measure a value which is indicative of the voltage drop at the terminals of at least one current source of the pixelated light source, it becomes possible to dynamically adapt the voltage delivered by the converter circuit.
