Abstract:
1. An optical module for automobile lighting devices adapted to selectively emit a principal light beam having an optical axis, comprising: (a) a reflector having an internal focus and an external focus on the optical axis; (b) a principal light source disposed at or proximate to the internal focus and adapted to selectively emit light rays for performing a primary lighting function; (c) a shield having a cut-off edge disposed at or proximate to the external focus; (d) a lens situated in front of the shield and having a focal plane disposed at or proximate to the external focus; (e) a secondary light source disposed between the shield and the lens and adapted to selectively emit light rays for performing a secondary lighting function; and (f)a retractable reflecting mirror movable from a retracted position, where the mirror does not substantially interfere with the principal light beam, to a working position in which the reflecting mirror is disposed at or proximate to the focal plane of the lens, substantially centered on the optical axis and oriented so as to give, from the light rays emitted from the secondary source, a secondary light beam substantially centered on the optical axis and comprising the secondary lighting function.
