LED signal lamp

In the present invention, there is disclosed a LED signal lamp consisting of a LED light source, a reflector and a cover glass wherein refractive catadioptric prisms (2), reflective elements (4) and dispersive elements (6) are used for adjusting emission of light from the LED source (1) wherein said reflective elements (4) are located on a surface (3) of defined form and said dispersive elements (6) are disposed on the cover glass (5). Said system of the reflective elements (4) lies on the defined form surface (3) being restricted for example by mounting dimensions. The system of reflective surfaces of the individual reflective elements (4) is selected so that the impinging parallel light beam is adjusted after reflection on these reflective elements (4) of the system to be parallel with the lamp optical axis, or dispersed with parameters meeting required distribution of light of the given type of the signal lamp. The system of dispersive elements (6) located on the cover glass (5) as well as the dispersive elements located on the surfaces of the individual reflective elements (4) serve for dispersion of the light beam, wherein the cover glass (5) is free of optical elements or is provided with a decorative optics, only.
