Abstract

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.
