Patent ID: 7136233

Claim:
A device for generating and projecting light marks, comprising a light source device for generating and radiating a primary light beam bundle, collimating optics for receiving the primary light beam bundle and for collimating, parallelizing and expanding the primary light beam bundle into a secondary light beam bundle and for radiating the secondary light beam bundle in a directed manner, and projection optics for receiving at least a portion of the secondary light beam bundle and converting the at least a portion of the secondary light beam bundle into at least one of a tertiary light beam bundle (L 3 ) and marking beam bundle for at least one light mark and radiating and projecting the at least one light mark, wherein the projection optics is acted upon by the at least a portion of the secondary light beam bundle such that a central beam bundle of the secondary light beam bundle can be radiated through an area of the projection optics, at least one marginal beam bundle of the secondary light beam bundle adjacent to the central beam bundle of the secondary beam bundle can be radiated directly past an edge or outer surface of the area of the projection optics, the central beam bundle of the secondary light beam bundle diffused through interaction with a cylindrical lens to be projected substantially in a shape of a line as part of the tertiary light beam bundle (L 3 ) or as a line mark beam bundle for a light mark, and the at least one marginal beam bundle (L 2 R) of the secondary light beam bundle can be projected substantially in one of a point and a spot as part of the tertiary light beam bundle or as a point mark bundle for a light mark.
