Claim:
1. An optical module of a lighting or a signaling device of a motor vehicle, comprising: a support, said support having a monolithic and plastic construction having a cooling opening; an optical lens; a heat exchanger having a plurality of fins that face said cooling opening; said heat exchanger receiving airflow caused by a fan that generates an airstream to cool said heat exchanger, said optical module having at least one other opening that cooperates with said cooling opening to enable said airflow generated by said fan to pass through said optical module; a first reflector associated with at least one first light source comprising an LED for reflecting light coming from said at least one first light source; and a second reflector associated with at least one second light source comprising an LED for reflecting light coming from said at least one second light source; wherein said optical lens, said heat exchanger, said first reflector and said second reflector being directly or indirectly carried by said support so that a chain of tolerances or dimensions for said optical lens, said heat exchanger, said first reflector and said second reflector passes through at least one of them; wherein said first reflector or said second reflector cooperates with said support to form an enclosure area for receiving the other of said first reflector or said second reflector; said first and second reflectors having generally curved or elliptical surfaces that face each other after said first and second reflectors are directly or indirectly mounted on said support; wherein said first reflector has a domed wall to guide the air leaving said cooling opening.
