ABSTRACT:
A traffic signalling apparatus wherein LEDs are employed to present various displays and the LEDs are secured with their sidewalls in a tubular holding device such that a good heat discharge from the LEDs to the holding device is guaranteed. The holding device is securely fixated in a front plate of the signalling apparatus, preferably detachably. An optical imaging device is additionally provided in order to achieve an emission characteristic which is optimized for traffic participants.
