- the technical field of the present invention is that of the optical modules intended to produce a light beam in order to illuminate a road taken by a carrier vehicle of this optical module.
- Such an optical module finds a particular application when it is installed inside a lighting and / or signaling device for a motor vehicle.
- Such an optical part is an isotropic and transparent element, and at least one of the faces is not flat, so as to converge or diverge the light.
- a light-emitting diode-type light source In the automotive lighting sector, it is also known to use a light-emitting diode-type light source. This type of source is accompanied by a device for igniting or extinguishing the source, and these two elements give off calories that a cooling device is responsible for dissipating into the surrounding environment.
- an optical part of the prior art with an assembly consisting of a light-emitting diode and its cooling device is achieved by interposing a part which maintains a certain distance between the optical part and the assembly.
- This is generally a plastic support which is fixed on one side, on the periphery of the optical part, and on the other on the assembly consisting of the light emitting diode and its cooling device.
- this support has many disadvantages. In the first place, this support forms a part which it is necessary to design, manufacture and install. This piece thus represents a cost that stresses the overall cost of the lighting function.
- this support is a part distinct and intermediate between the set referred to above and the optical part.
- the latter must be installed in a precise orientation with respect to the assembly, it is then necessary to manage, on the one hand, very precisely the chain of ribs connecting these components, and on the other hand, to guarantee a tolerance 5 of minimal manufacture of this intermediate support.
