Signaling lamp for cars

摘要

An optical plate (20) is curved and possesses optical arrangements (22,23) which have different light transmission coefficients. A piston brings about a given distribution of the light which takes into account the different light transmission coefficients mentioned in order to get on the outside of the plate a development of the illumination intensity corresponding to the given direction, which corresponds to a specified pattern. The signaling lamp comprises a light source (10,12), and an optical plate which possesses optical arrangements that can direct the light coming from the region of the light source, designed so that it expands with an average direction that runs parallel to a horizontal optical axis. A piston receives and distributes the light beam (30) which is inserted between the light source and the optical plate and is in the position to bring about a given distribution of the light on the inner surface of the optical plate in at least a given direction. An Independent claim is included for a method for manufacturing the signal lamp.
