Abstract

A lens for a traffic light has a convex outer surface and a concave inner surface with raised elements formed, at least in the central part of the lens, by prism segments (1, 2, 3) with curved surfaces having generators extending in substantially parallel planes and at varying angles to a plane (P) tangential to the outer surface of the lens, at the centre thereof.
