Abstract (en)
[origin: EP2113439A2] The traffic signal has an optical system (3) for radiation of light in a solid angle, particularly for displaying signal aspects during rail-bounded traffic routes. A filament arrangement is replaced by a light emitting diode arrangement with filament specific characteristics, particularly geometrical dimensions, luminous flux amount and luminous flux distribution. The light emitting diode arrangement has a light emitting diode (5) and an optical element (6).
