Other features and advantages of the present invention will be better understood with the aid of the description and the drawings of which: FIG. 1 is a top view of a motor vehicle comprising a transparent or translucent panel in accordance with FIG. invention; - Figure 2 is a schematic view of the panel according to the invention of the motor vehicle of Figure 1 in a first embodiment; - Figure 3 is a schematic view of a panel according to the invention of the motor vehicle of Figure 1 in a second embodiment;
    Figure 1 is a top view of a motor vehicle 2 according to the invention. The vehicle comprises a body 4 and a transparent or translucent panel 6 according to the invention covering an opening of the bodywork. The transparent or translucent panel comprises a plate 8 of transparent or translucent material with two opposite main faces and at least one input side face 12 of non-visible electromagnetic radiation. For example, the input side face is shown on the right of the bodywork but this does not limit the invention, the input side face can be as well front or rear or on the opposite side of the plate. The panel 6 may also include several side faces of non-visible electromagnetic radiation input. The panel 6 comprises optical elements 14 in phosphor material located in the transparent or translucent material of the plate and configured to convert the non-visible electromagnetic radiation, received from the input side face in question, into one or more light beams to a light source. main faces. The phosphor optical elements are in this case intended to transmit one or more light beams to the inner face of the plate. By phosphor material is meant a material capable of causing a Stokes shift, that is to say a wavelength jump of a radiation. In other words, the optical elements 14 in phosphor material receive non-visible electromagnetic radiation which produces a molecular excitation consecutively generating a transmission of visible electromagnetic radiation. The plate 8 may be of mineral or organic material and the optical elements 14 may be embedded in the transparent or translucent material of the plate. In the configuration of a plate of organic material, the latter may be of thermoplastic material. This measurement is interesting in that the optical elements can be molded in the mass with the plate. In particular, the optical elements may be configured to convert electromagnetic radiation in the infrared range into the light beam (s). The infrared domain is a radiation domain of wavelength greater than 0.7 μm and less than the wavelengths of microwaves which are of wavelength greater than 1000 μm. The evoked infrared radiation range, however, does not limit the invention, the elements may be configured to convert electromagnetic radiation not visible in the ultraviolet range.
    The phosphor material of the optical elements 14 may comprise phosphorus and one or more of the optical elements may be holographic elements capable of generating one or more relief patterns. This measurement is interesting for producing light patterns of substantially complex shape. Infrared radiation on holographic elements can be searched for a particular light rendering. The panel may comprise one or more sources (not shown) of non-visible electromagnetic radiation and a pattern controller (not shown) coupled to the or each of the sources of electromagnetic radiation. This measure of the invention is interesting for producing animated light patterns on the inside of the visible plate of the vehicle interior. It can be seen in the image that the panel comprises phosphor optical elements representing by way of example a logo.
    Figure 2 is a schematic view of a transparent or translucent panel 6 according to the invention and in a first embodiment. The panel comprises a transparent or translucent plate 8, a non-visible radiation source 16 and a luminophor optical element 14. The uniqueness of the source and the optical element shown in the image is a schematic representation of the compliant panel according to the invention, the panel may comprise several radiation sources and several phosphor optical elements; the number of sources is also not substantially corresponding to the number of optical elements. The sources of electromagnetic radiation 16 are arranged along the input side face 12 of the radiation. Non-visible electromagnetic radiation 18 shown in the image propagates in the plate between the input face 12 to a phosphor optical element 14. Several light beams 20 transmitted by the phosphor optical element 14 can be seen in the image. towards a main face 22 of the plate. The main face 22 in question is intended to form the inner face of the plate 8 vis-à-vis the interior of the vehicle once mounted to the vehicle so that the light projection can be visible to the passengers of the vehicle. In addition, the pattern controller 32 coupled to the non-visible electromagnetic source can be seen.
    The second embodiment of the invention will be described with reference to FIG. 3. The reference numerals of the first embodiment of FIGS. 1 and 2 are used to designate identical or corresponding elements, these numbers being however increased by 100 in order to clearly distinguish the embodiments.
    Figure 3 is a view of a transparent or translucent panel 106 according to the invention and in a second embodiment. The panel 106 comprises a transparent or translucent plate 108, a non-visible radiation source 116 and a phosphor optical element 114. The uniqueness of the source and the optical element represented in the image is a schematic representation of the 'invention. It can be seen that the panel also includes an optical guide 130 extending along the input face 112. The electromagnetic radiation source 116 is optically coupled to the optical guide and the guide is configured to emit the radiation to the side face This measurement of the invention is interesting in that the guide 130 makes it possible to enlarge the region of the plate receiving the non-visible electromagnetic radiation. A single guide is shown, this does not limit the invention. The panel may include several guides and several light sources coupled to the guide or each of the guides. Non-visible electromagnetic radiation 118 shown schematically in the image propagates in the plate 108 between the input face 112 and the phosphor optical element 114. This radiation comes in this case from the electromagnetic source of non-visible light 116 coupled to the guide 130, the latter emitting the radiation to the side face 112. It can be seen in the image shown several light beams 120 transmitted by the phosphor optical element to a main face 122 of the plate. The main face 122 in question is an inner face of the plate 8 so that the light projection can be visible to the passengers of the vehicle. In addition, the pattern controller 132 coupled to the non-visible electromagnetic source can be seen.
    It should be noted that the first and second embodiments shown respectively in Figure 2 and Figure 3 can be combined.
