A lighting system for automobiles is proposed which includes a laser light source emitting a primary laser light bundle within a solid angle area around a beam direction, a photoluminescence element positioned within the emitted primary light beam, and a protective element that protects against stray laser rays. The photoluminescence element is configured to absorb the laser rays impinging on said element and by means of the photoluminescence to radiate secondary light rays. The lighting system includes a protection system with a protective element of an elongated shape having a first end and a second end, wherein the first end of the protective element is positioned within the beam direction of the primary light beam and downstream of the photoluminescence element.

Lighting system with a laser light source for a motor vehicle

A method and a device for the reduction of margins of the light image of a headline, and the headline incorporating the device, is provided, having a reflective diaphragm which is adapted to be shifted in a light axis direction within adjustment limits of a longitudinal position. The margins of the light image can be detected by an optical colour-sensitive photometric sensor, and colour characteristics of the light image margins can be evaluated by identifying a current position of the reflective diaphragm. The reflective diaphragm can then be fixed in the longitudinal position corresponding to selected colour characteristics of the light image margins. The reflective diaphragm can also be adapted to be shifted in a direction perpendicular to the light axis direction.

A projector headlamp includes light sources, a cooling system and reflector comprising an upper part with a first focal point and second focal point and a lower part with a first focal point and second focal point. The headlamp also includes an aperture with a cutoff edge proximate an optical axis of the headlamp and a convergent lens. The convergent lens includes at least two segments with their own first focal points, the first segment in a lower part of the convergent lens has a greater optical power than a second segment in an upper part, the first focal points of the segments located near the optical axis of the headlamp between the light sources and the lens. The light sources comprise at least two light sources, a first adjoins the first focal point of the upper part and a second adjoins the first focal point of the bottom part.
