  • Patent number: 11402734
    Abstract: A multi-lens array is provided for a luminous source of a vehicle. The array includes at least one light source and multiple lens arrangements. Each lens arrangement includes a condenser lens and a projector lens as optical elements. The at least one light source is enabled to expose each of the multiple lens arrangements with light, and the projections of the multiple lens arrangements of this light interfere to form a single projected image.

  • Patent number: 11199302
    Abstract: A light of a vehicle with a cover lens, the light having a light source for generating light, the light having a shifter for shifting the wavelength of at least a portion of the light generated by the light source in the visible, short-wave range into radiation in the long-wave range, the shifter being disposed in the light in such a way that the long-wave radiation generated by the shifter is directed towards the cover lens.

  • Patent number: 10124717
    Abstract: A customizable modular lamp is made up of an outer lens customized by known per se techniques, which covers a housing provided with at least one recess in which is mounted a customizable module consisting of a retro-reflective lens under which there is an inner customized lens personalized by known per se techniques, under which there is a printed circuit board with LEDs that is held in a holder fastened to a cover provided with at least one element for ventilation. During the daylight, personalization is visible on the outer customized lens. In the darkness and—depending on the recipient's request—when activating the lights for changing direction, position or braking, customization becomes evident by lighting inside the lamp, on the surface of the inner customized lens.
