Optical module for lighting and signaling device such as headlight type lighting device, of motor vehicle, has reflectors that are formed on part equipped with cooling opening for circulation of cooling air

摘要

The module (1) has reflectors (6, 7) associated with a light source i.e. LED, to reflect light coming from the light source. The reflectors are formed on a part equipped with a cooling opening (50) for circulation cooling air. A heat exchanger (4) is equipped with one or more cooling ribs (51) extending partially in the cooling opening. The reflectors comprise a convex wall (52) arranged for guiding the air coming from the cooling opening. A support (2) carries an optical lens (3) and the heat exchanger, where the support is obtained by molding plastic.
