  • Patent number: 12209724
    Abstract: A problem to be solved by an embodiment of the present application is how to make the structure of a vehicle lamp more compact. According to an embodiment of the present application, an outer lens is provided, wherein the outer lens comprises: a first lens portion; and a reflecting portion, the reflecting portion being disposed on at least one side of the first lens portion, in close contact with the first lens portion, and capable of reflecting a light beam entering the first lens portion so that the light beam is propagated inside the first lens portion. Compared with the prior art, the present application has the following advantages: the structure of the outer lens is more compact, the overall volume of the vehicle lamp is smaller, and the light output is more uniform.

  • Publication number: 20240418338
    Abstract: The invention relates to an optical module for a light-emitting device of a motor vehicle including a first light source able to emit light rays. A light guide including a first coupling face able to receive light rays emitted by the first light source and able to scatter light rays propagating through the light guide over all or some of its perimeter. A transparent or translucent exit lens, with the exit lens defining a housing in which most of the light guide lies, so that light rays scattered by the light guide pass through the exit lens. A deviating member placed in the housing facing the light guide and arranged to redirect light rays scattered by the light guide toward this deviating member in the direction of the exit lens. A sealing member arranged to keep the deviating member in the housing and to obturate the housing.

  • Publication number: 20240414816
    Abstract: The invention relates to a vehicle part intended to be placed facing an emission cone of a radar sensor, the radar sensor being configured to emit an electromagnetic wave the electric field of which includes a component oscillating in a direction of interest. The vehicle part includes a system for deicing the part. According to the invention, the deicing system includes a set of slender heatable elements, at least one sub-set of the set of slender heatable elements being located in the emission cone of the radar sensor and being configured so that each slender heatable element of the sub-set is placed on the part so as to extend in a direction substantially perpendicular to the main polarization direction of the radar sensor when the part is placed facing the radar sensor.

  • Patent number: 10760763
    Abstract: A lighting module intended to be placed behind a translucent or transparent outer lens or window, the module including: a place for at least one light source that is able to emit light rays; and an optical system that is able to deviate the light rays emitted by the one or more light sources so as to form a light beam along an optical axis of the module, the optical system extending in a main direction that is transverse to the optical axis and including an exit face for rays. The exit face of the optical system has in sagittal cross section a concave or convex curved general profile.

  • Patent number: 10118540
    Abstract: A signaling and/or lighting device for a motor vehicle, notably a stop light for a rear window of a motor vehicle, including a printed circuit received by a support. The printed circuit includes at least one light source an emitting face of which is oriented toward an optical lens of the device, the emitting face being generally perpendicular to the optical axis of the lens. The printed circuit support makes it possible to receive the latter at a plurality of predetermined distances relative to the optical lens, thereby assuring the focusing of the light emitted by different types of light sources that can be used in the device.
