Light signal installation e.g. traffic lights for road intersection, with phantom light suppression provided by non-reflective partition walls within rear reflector enclosing signal lamp

摘要

The light signal installation has at least one lamp (7) enclosed by a rear reflector (5) fitted with a front disc (6) and provided with a number of non-reflective partition walls (1,2) in the plane of the reflector axis and a non-reflective surface around the apex point of the reflector. The partition walls are arranged in at least 2 groups, the first group attached radially to a conical non-reflective mantle (1a) with its open side fitting above the lamp and the second group attached radially to a truncated conical non-reflective mantle (2a) enclosing the lamp socket.
