- said adapter fixing means 126 comprise another notch 126b capable of receiving the metal fastening rod 190, so that each notch 126a, 126b defines a different fastening position of the metal rod. .
- the rod is positioned in the intermediate notch 126b, allowing pre-positioning of the module before its final fixing, for example to adjust it correctly before folding it down. Then, the rod is placed in the final notch 126a to permanently fix the adapter 170 to the module 120.
- the term "definitive" means definitive to operate the module and not for the entire life of the module, since according to the invention this fastener is removable to allow the replacement of the light source by removing and replacing the adapter.
- the support block that comprises the adapter 70, 170, 270 is a radiator whose fins 75, 175, 275 are arranged to dissipate the heat released by the LED 13. is all the more effective as they are oriented upwards.
- the adapter 70, 170, 270 includes a connector 82, 182, or 282, connected to the LED 13, and the carrier 20, 120, and 220, also includes a connector 82, 182.
- these connectors are arranged one above the other when the adapter 70 is positioned in the support, so that during assembly the simple fact of folding the adapter against the module will plug the connectors into each other.
- the connector 382 of the adapter 70 can comprise connection pins 384, 385, the connector 502 of the support plugging in its pins 504, 404, between those of the connector of the adapter.
- the pins of the connector of the support 20 comprise blades 516 mounted on more rigid portions 514 between which the central pin of the connector of the adapter is plugged, the rigid parts 514 are housed between the walls 484 of the 70.
- the rigid portions 514 are connected to the support 20 via a spring 518 making it possible to reduce the size tolerances for mounting when the adapter 70 is fastened.
- the contact surfaces 76 of the adapter 66 and the support are in direct contact.
- the optical element having a game along an axis perpendicular to the tangent to these surfaces, or along the vertical axis Z in the illustrated embodiments.
- This clearance may for example be between 0.1 and 2 mm, preferably between 0.5 and 1 mm, preferably 0.5 mm.
- the contact surfaces 66 of the support and / or the contact surfaces 76 of the adapter are covered by a compressible element and thermally conductive, in particular a silicone charged, for example a PAD 900 silicone.
- This compressible element may have a thickness of about 229 ⁇ .
- the adapter is in direct contact with the optical element 12, so that the adapter 70, 170, 270 is indexed with respect to the optical element 12 along the vertical axis Z.
- the contact surfaces 66 and 76 are in direct or indirect thermal contact so that the adapter 70, 170, 270 and said support 20, 120, 220 of the optical element 12 form a single heat sink, the fins being located for some - 75, 23, 24, 25; 175, 123, 124, 125; 275, 223, 224, 225 - on the adapter 70, 170, 270 and for other on the support 20, 120, 220.
