Abstract: The present invention is for a lighting device by which a controlled light pattern is obtained from a specific light source. The device comprises a light source which emits several parallel light beams. There is one prism (3) for each light beam (8), which passes through the lighting device. All of the prisms are integrated parts of a common disc. Preferrably the light source comprises several light emitting diodes (1) each emitting one light beam. The prisms are suitably made as straight, circular cylinders, at least those parts thereof which protrude from the common disc. The oblique surface may be freely varied at both its angle at the axis of the cylinder and direction whereby the direction of the corresponding light beam may be controlled.
