Description

FIELD OF APPLICATION The present invention relates to an automotive lighting and/or signaling device. BACKGROUND ART The term automotive lighting and/or signaling device is used herein in a very broad meaning, so as to comprise both a rear and a front automotive lamp, the latter also being called headlight or headlamp. Therefore, a position light, a direction indicator light, a stop light, a rear fog light, a reversing light, a dipped-beam headlamp, a high-beam headlamp and the like, are included. Furthermore, the term is also meant to comprise a map light, a light for a dashboard or part thereof; therefore, the automotive lighting and/or signaling device may be located both inside and outside the vehicle. As known, said automotive lighting and/or signaling devices may be used both for lighting and for sending visual signals. To this end, said devices comprise a plurality of illuminating portions having different colors, different levels of brightness (also according to regulations to be complied with) and the like. In particular, in recent years, lighting and/or signaling devices have increasingly acquired an aesthetic value as well as a photometric function. In other words, apart from, of course, the lighting and/or signaling function which they must carry out, said lighting and/or signaling devices are increasingly used as design elements within the context of the vehicle in which they are inserted. To this end, providing lighting and/or signaling devices which have illuminating portions having particular drawings and/or geometries and/or writings or symbols, as required by vehicle manufacturers, is known. To obtain automotive lighting and/or signaling devices which satisfy such requests, providing devices with multiple luminous sources and multiple lenticular bodies equipped with masks and colored portions is known. The colored portions have the function of carrying out both photometric functions as well as aesthetic functions; the masks are used to conceal the presence of the internal components of the lamp from the outside and to delimit the different lighting areas which are to be obtained. Such solutions imply the realization of many components of the lamp which must be suitably assembled together: the result is a lighting and/or signaling device which is expensive and complex to make, as well as relatively heavy and bulky. US 2014/160779 A1 describes a lighting device of the prior art. PRESENTATION OF THE INVENTION The need is therefore felt in the background art to provide an automotive lighting and/or signaling device which allows to obtain the above mentioned technical effects, with an excellent aesthetic result, both in terms of precision of the illuminating portions as well as in terms of lighting homogeneity, without implying excessive construction and assembly costs, and limiting weight and size. Such requirement is met by an automotive lighting and/or signaling device in accordance with claim 1. Other embodiments of the present invention are described in the dependent claims. DESCRIPTION OF THE DRAWINGS Further features and advantages of the present invention will become more apparent from the following description of preferred and non-limitative embodiments thereof, in which: Figure 1 shows a perspective view, with separate parts, of a lighting and/or signaling device according to an embodiment of the present invention;Figure 2 shows a sectional perspective view, with separate parts, of the lighting and/or signaling device of Figure 1;Figure 3 shows a perspective view, with separate parts, of a lighting and/or signaling device according to a further embodiment of the present invention;Figure 4 shows a sectional view, in an assembled configuration, of the lighting and/or signaling device of Figure 3. The common elements or parts of elements between the embodiments described below will be indicated with the same reference numerals. DETAILED DESCRIPTION With reference to the aforesaid figures, reference numeral 4 generally indicates a lighting and/or signaling device, such as an automotive lamp, to which the following description will refer without this implying any loss of generality. As mentioned above, the term lighting and/or signaling device indifferently means an automotive rear lamp or an automotive front lamp, the latter also called headlight or headlamp, comprising an external vehicle light having a lighting and/or signaling function, such as, for example, a position light, which may be a front, rear, side position light, a direction indicator light, a stop light, a rear fog light, a high-beam headlamp, a dipped-beam headlamp and the like. Furthermore, the term lighting and/or signaling device also means an inside map light, a light for a dashboard or part thereof, a display and so on. Therefore, as better described below, in the signaling function thereof, the device may comprise the possibility of sending luminous signals, logos, but also luminous messages and writings of any kind.
