5. The adapter as claimed in claim 2 , wherein said metal rod comprises a gripping portion in the form of a loop intended to be gripped to allow said metal rod to be unhooked or unlatched from a mating hook.
6. The adapter as claimed in claim 2 , in which said metal rod is in the form of a loop articulated on one side and with a portion suitable for cooperating with a notch on said support.
7. The adapter as claimed in claim 1 , comprising a connector connected to said at least one light source and suitable for being connected to an electrical power source to power said at least one light source.
8. An optical module for a motor vehicle lighting and/or signaling device, comprising:
a first optical deflection element;
a support of said first optical deflection element, said first optical deflection element being fixed to said support;
wherein said optical module comprises adapter fixing means; and
an adapter being adapted to be fixed to said support of said first optical deflection element via said adapter fixing means;
wherein said adapter fixing means comprises a metal rod pivotally coupled to at least one of said support or said adapter;
wherein said adapter comprises a printed circuit board to which at least one light source is fixed and connected.
9. The optical module as claimed in claim 8 , wherein said support comprises a toothlike projecting part housed between two fins of the adapter.
10. The optical module as claimed in claim 8 , wherein said support comprises a toothlike projecting part, and said metal rod enabling said adapter to be fixed to said adapter fixing means, said toothlike projecting part comprising the articulation of said metal rod.
11. The optical module as claimed in claim 8 , wherein said metal rod is articulated at one end to said support, and an attachment part of said metal rod is attached to said adapter fixing means formed by said support, said metal rod comprising a pressing portion situated between said articulated end and said attachment part, said pressing portion bearing against said adapter, so as to press the latter against said support.
12. The optical module as claimed in claim 7 , wherein said adapter has contact surfaces pressed into direct or indirect contact with contact surfaces of said support.
13. The optical module as claimed in claim 7 , comprising a compressible and thermally conductive element, notably a charged silicone, situated between contact surfaces of said adapter.
14. The optical module as claimed in claim 7 , wherein contact surfaces of said adapter are in direct or indirect thermal contact such that said adapter and said support of an optical deflection element form a single heat dissipater.
15. The optical module as claimed in claim 14 , wherein said single heat dissipater comprises fins situated on said adapter, and said fins on said support.
16. The optical module as claimed in claim 8 , wherein said adapter fixing means comprising said metal rod, which is pivoted at one end on said adapter, said metal rod further comprising a fixing part to be fixed to an element, said metal rod being arranged to allow compression fixing of said adapter to said element.
17. The optical module as claimed in claim 8 , wherein said support comprises:
an opening facing said optical deflection element;
guide fins on either side of said opening, notably parallel with one another; and
bearing surfaces between said opening and said guide fins
said guide fins being arranged so as to allow a block having a width close to the distance between said guide fins to be guided in order to position it in contact with said bearing surfaces.
18. The adapter as claimed in claim 1 , wherein said at least one light source is a light emitting diode.
19. The optical module as claimed in claim 9 , wherein said adapter comprises said metal rod pivotally coupled to said adapter and enabling said adapter to be fixed to said support.
