Abstract

Refractive lens for semaphore, being of the type of lenses used in traffic control traffic lights, whose optical signals are based on the corresponding luminaires constituted by an incandescent lamp and a reflector or led diodes, presenting a refractor lens of the relative color to the optical signal represented, so that the refractory lens for traffic light is constituted by a concave-convex circular body with a completely smooth convex external surface and a concave internal surface, characterized in that in the concave-convex body constituting the refractive lens (1) a central circular surface (2) is defined, according to two semicircles with respect to its vertical central plane and a circular crown surface (3), its internal surface being defined by a plurality of small magnifiers (4) of asymmetric hexagonal shape, being arranged the small magnifying glasses (4a) and (4b) relative to the central circular surface (2) with its e greater in a vertical direction, while the small magnifying glasses (4c) relative to the circular crown surface (3) remain with their major axis in the horizontal direction.
