Abstract (en)
[origin: EP0741275A2] From the light source (1) a bundled beam (12) can be produced. In the refraction lens (16,17), a first part of the beam for prodn. of the target beam (3) is allowed through in an unaltered state and a second part is refractable for prodn. of the lighting field. The refraction lens is divided into a first and a second area, whereby the first part of the beam enters through the first area and the second part of the beam through the second area. The refractive lens is spaced in the first part and in the first area acts optically as a plan-parallel plate. The refraction lens has at least one convex surface and the first area extends around a highest point of the convex surface.
