  • Patent number: 12326232
    Abstract: A lighting device for a vehicle headlamp includes a plurality of light sources; a first lens element (FLE) downstream of the light sources; and a second lens element (SLE) downstream of the FLE. A light receiving surface (LRS) of the FLE is formed by a main-area and a sub-area. The light sources and LRS are distanced to each other whereby a first fraction of light is emitted towards the sub-area and a second fraction is emitted towards the main-area. The light sources, FLE, and SLE are configured to create a complete or partial, preferably adaptive, high beam light distribution with two sections. The sub-area and main-area are configured to refract impinging light, wherein refraction of light by the sub-area and main-area is such that a first intensity maximum of a first section is vertically lower in front of the lighting device than a second intensity maximum of the second section.

  • Publication number: 20240377043
    Abstract: Illumination device for a motor vehicle headlight. The device has a light source, a light-permeable body (LPB), a light injection element for injecting light from the light source into the LPB, and a projection device. Light from the light source forms a light distribution with a cut-off line formed by a screen edge of a screen device, which is formed by a boundary surface of the LPB. A sign light light source (SLLS) and a further sign light light injection element (SLLIE) associated with the SLLS are provided. The SLLIE forms the light emitted by the SLLS into a third light beam and directs the third light beam onto the boundary surface, which re-enter the LPB and are projected by the projection optics device as a sign light light beam into a region of the light distribution lying above the cut-off line and are displayed as sign light light distribution.

  • Patent number: 12013095
    Abstract: A lighting device (1) for a vehicle headlamp is provided. The lighting device includes an illuminant (2), a collimator (4), a mirror device (5) with a reflection surface (5a), and a DMD device (6). The mirror device (5) is arranged downstream of the collimator (4), wherein the reflection surface (5a) of the mirror device (5) is configured to reflect a first part of the light from the illuminant and to transmit a second part of the light from the illuminant. The mirror device (5) is configured in such a way that the reflected part is free of UV light and the transmitted part has UV light. The DMD device (6) is configured to modulate and deflect the first part of the light from the illuminant.
