  • Publication number: 20240027046
    Abstract: A vehicle headlamp includes a housing closed by a transparent outer lens and, inside the housing, a lighting module that emits a light beam in the direction of an optical axis defining a cone of light and a transparent screen that is positioned between the lighting module and the outer lens and receives, in its thickness, a light beam emitted by a light source. An internal face of the screen is provided with optical modules that reflect the light emitted by the light source in the direction of the outer lens. The outer lens forms a first angle of 60 to 100° with the optical axis of the lighting module and the screen forms a second angle such that a part of the cone of light of the light beam that is situated beneath the optical axis is reflected by the screen above the lighting module.

  • Publication number: 20200393104
    Abstract: A vehicle light device includes a primary light source configured to emit first light having wavelengths in a first wavelength range, and a conversion element including an input end and an output end, the input end being optically coupled to the primary light source. The conversion element includes a nonlinear optical medium configured to convert at least a portion of the first light to second light having wavelengths shifted from the first light such that the output end outputs collimated light having a broad wavelength range including wavelengths of the first light and wavelengths of the second light. An outer lens is optically coupled to the output end of the wavelength conversion element and configured to transmit the output light as white light for illuminating a path of a vehicle.

  • Publication number: 20200200355
    Abstract: A light device for a vehicle includes an enclosure having a transmissive portion configured to transmit light generated within the enclosure. A matrix material is contained within the enclosure and includes quantum dots dispersed throughout the matrix material. An energy source is configured to couple energy to the quantum dots such that the quantum dots emit light that is transmitted through the transmissive portion of the enclosure.

  • Publication number: 20190049648
    Abstract: A light guide, a method, and an apparatus for automotive lighting are provided. The apparatus includes a light source and a light guide. The light guide includes an entry side having at least one discontinuity, an output side, and a total internal reflection side. The at least one discontinuity includes a diopter and is configured to modify angles of incidence of light rays with respect to the total internal reflection side to correct an optical path of at least a portion of the light rays, the light rays are input via a portion of the entry side and exit the light guide through the output side.

  • Publication number: 20180328564
    Abstract: A lighting device, for a motor vehicle, including a transparent or translucent screen; and a lighting module able to project a light beam onto the screen. The screen includes a first diffusive area and a second non-diffusive area, such that a first part of the light beam, projected onto the first area, is diffused by the screen and that a second part of the beam is transmitted by the screen to an external projection surface.
