Complex reflector formed by sectors with rotational symmetry for a vehicle headlamp, and process of manufacture

摘要

A reflector (15) for a vehicle headlamp capable of generating a light beam and directing it with respect to an optical axis (Z) in order to illuminate the surrounding space according to a predetermined luminosity distribution is described. The reflector (15) is subdivided into a plurality of reflecting sectors (15a, 15b) capable of reflecting the light emitted from a light source (11) located along an optical axis (Z) of the headlamp (10) in order to obtain the said luminosity distribution. Each segment (15a, 15b) of the reflector (15) is formed by a portion of a surface having rotational symmetry about a corresponding axis. This axis is orientated with respect to the optical axis (Z) of the headlamp in such a way that the corresponding sector (15a, 15b) is capable of directing the light from the light source (11) into a predetermined spatial region of the luminosity distribution. <IMAGE>
