  • Patent number: 11953173
    Abstract: An illumination apparatus for vehicles having a light source, a support plate for receiving the light source, and an optical unit arranged in front of the light source in the main emission direction to deflect light emitted by the light source onto a roadway in front of the vehicle in accordance with a predetermined light distribution. The light source has a light-emitting surface and a light source frame surrounding the same. The light source is surrounded by a shielding frame with a wall that is raised in the main emission direction and encloses an intermediate space between the light source and the optical unit.

  • Patent number: 11879611
    Abstract: A light module is provided with a bulb shield. The light module includes a light generation unit for emitting light and an optic for shaping the light emitted by the light generation unit. The light generation unit includes a light-emitting surface. A bulb shield is arranged between the optic and the light generation unit for covering the light generation unit. The bulb shield includes a passage for the light emitted by the light-emitting surface. The light module includes a bearing structure for the bulb shield. The bulb shield is glued to the bearing structure by a first adhesive bond and the bulb shield is glued to the bearing structure by a second adhesive bond. A first adhesive used to produce the first adhesive bond and a second adhesive used to produce the second adhesive bond are different.

  • Patent number: 11732856
    Abstract: A lighting device for vehicles having a first light source, a second light source and a light-shaping apparatus allocated to the first light source and the second light source, wherein the second light source is offset in relation to the first light source, at least in a direction running perpendicularly to the optical axis of the light-shaping apparatus. The light that is incident on the light-shaping apparatus from the first light source is deflected to produce a first light function and wherein the light that is incident on the light-shaping apparatus from the second light source is deflected to produce a second light function, wherein the light-directing surface of the light-shaping apparatus has a free-form surface comprising multiple varyingly curved surface elements.

  • Patent number: 6971778
    Abstract: A headlight for vehicles with a projection module is provided, which includes a bowl-shaped reflector, an illumination unit dedicated to the reflector, a lens, and a shutter arranged between the lens and the reflector. The shutter forms a light-dark-border of a light bundle. The lens features a convex front side facing away from the reflector and an optical element mounted to the headlight in the lower middle margin area on the front. The light beams emerging from the optical element are directed to an area above the light-dark-border of the light bundle of the headlight. In vertical second planar sections, to which the optical axis of the projection module extends perpendicularly, the surface of the optical element is concave-shaped, and in vertical planar sections extending parallel to the optical axis, it is convex-shaped.
