A light trap for ultraviolet radiation for curing ink on a printing substrate contains a shaped body with more than two shape elements succeeding one another. The shaped body has a side facing the printing substrate and embodied to have step elements in a stepped arrangement as shape elements. Every step element contains a pair formed of a step surface and a riser, the step surfaces and the risers having different inclinations relative to the direction of transport. The step surfaces have a step length L and the riser has a step height H, and is characterized in that the following applies: L>2H. This provides an improved UV screen by use of the light trap while simultaneously simplifying the process of cleaning the light trap. This is preferably used in the process of printing and curing UV inks.

The invention relates to a laser lighting device for vehicles comprising two or more laser light sources, wherein each is configured to generate a primary laser light beam, a light guide associated with each laser light source, wherein each primary laser light beam is coupled into the first end of the guide and coupled out of the second end of the guide as a secondary laser light beam, and each secondary laser light beam is directed onto a light conversion means so as to generate a predefined luminous image thereon, which via a projection system associated with the light conversion means is projected as a light image onto the roadway, wherein each primary laser light beam has a first intensity profile, each secondary laser light beam has a second intensity profile different from the first intensity profile, and each secondary laser light beam is directed via a microscanner onto the light conversion means.
