  • Light signalling device
    Patent number: 4962450
    Abstract: A light signalling anti-phantom device includes a collimator with a reflector (2), a light source (1) disposed in the focal point (F) of the collimator, and an absorber (3) of light. The reflector (2) and absorber (3) are arranged so that any focal ray (4) directed in opposition to the focal ray (5) incident on the reflector (2) falls on the absorber (3). The reflector (2) may be a mirror or catadioptric rings (23) exhibiting total internal reflection. This design eliminates false external illumination signals and makes light signals more contrast during daytime.
