Device for producing and projecting light marks

The device has a light source device (Q) for generating and radiating a primary light beam bundle (L1), collimating optics (K) for receiving the primary light beam bundle (L1) and for collimating, parallelizing and expanding the primary light beam bundle (L1) into a secondary light beam bundle (L2). The secondary light beam bundle (L2) is collimated in a directed manner and projection optics (P) receive a portion (L2Z) of the secondary light beam bundle (L2) which is converted into a tertiary light beam bundle (L3). The beam bundle (LM) is marked for a light mark (ML, MP) and radiated and projected. The projection optics (P) is acted upon by one of the secondary light beam bundle and a portion of the secondary light beam bundle so that central beam bundle of the secondary light beam bundle can be radiated through an area (ZA) of the projection optics (P). A marginal beam bundle (L2R) of the secondary light beam bundle is adjacent to the central beam bundle of the secondary light beam bundle can be radiated directly past the edge or outer surface of the area of the projection optics. The central beam bundle of the secondary light beam bundle is diffused through interaction with the cylindrical lens (Z) and can be projected substantially in the shape of a line as part of the tertiary light beam bundle or as a line mark beam bundle (LML) for a light mark (ML). A marginal beam bundle of the secondary light beam bundle can be projected substantially in a point and a spot as part of the tertiary light beam bundle or as a point mark bundle (LMP) for a light mark (MP).
