Abstract (en)
[origin: WO2011023480A1] The invention relates to a light signal comprising a semiconductor light source (2) and a convex lens system (11) for representing signal aspects, especially on rail-bound traffic routes. In order to eliminate the need for monochrome semiconductor light sources, the semiconductor light source (2) is a white point light source, a signal aspect-specific color filter being provided in the aperture region of the point light source.
