Definitions
- the invention relates to a motor vehicle light comprising at least one lamp, a reflection or refraction element arranged in correspondence with this lamp to reflect or refract light in the form of a beam of substantially parallel rays, an intermediate screen arranged in front of the lamp and of the reflection or refraction element chosen and formed by a plate of transparent material of which, on the one hand, the internal face is provided with convergence dioptres each aligned on one of the transparent zones arranged on the external face of the intermediate screen which, on the other hand, is covered with an opaque mask provided on the same alignment with orifices for the passage of the brushes of light concentrated by said dioptres, a front covering screen closing off the whole at the front of said light and provided with an optic spreading and distributing as appropriate said elementary brushes to form the lighting beam or external signage expected.
- an arrangement of this kind is produced in numerous automotive signaling lights in which the covering screen has an arrangement of vertical and horizontal diffusion dioptres under the general shape of spherical caps (balls) and / or tori on its internal surface, (preferably in the crossed arrangement of parallel cylindrical lenses on each of the two faces of the covering screen set out in the aforementioned patent), dioptres which reinforce the divergence of the elementary light brushes at the outlet of the orifices of the mask in order to achieve the required spreading of the external lighting beam.
- the present invention aims to achieve a masked type fire mentioned in the introduction, but capable of meeting the style requirements mentioned above.
- the fire according to the invention is characterized by the fact that said convergence diopters are arranged so as to focus forward the parallel incident rays which the intermediate screen receives from the chosen upstream reflection and / or refraction means of the lamp rays, the intermediate screen being provided on its outer wall of a corresponding arrangement of diverging diopters on the one hand positioned in the axis of each of the converging diopters and capable of enveloping the entire convergent volume of each functional light brush focused by said convergence dioptres, and of straightening above all their elementary rays in a direction substantially parallel to the original incident rays, on the other hand located in very slight withdrawal from the flat surface and / or radiated by substantially vertical bands regulating the external relief of the external wall of the intermediate screen which is itself covered, with a layer of opaque material, which masks in external vision, extinguished fire, a coloring element chosen from the functional light beam and determines in the alignment axis of each of the above-mentioned convergence and diverg
- the light passage orifices of the mask of opaque material of the intermediate screen consist of grooves of small width separating between them the various bands of optical appearance which regulate the relief of the external wall of said intermediate screen, and at the bottom of which grooves are made substantially set back the righting diopters, said bands accentuating the pitch of the aspect relief of the optical elements of the covering screen which is seen from the outside.
- the dioptres of divergence of the intermediate screen produced in very slight withdrawal from the flat and / or radiated surface of the bands of optical appearance regulating the external relief of said screen are arranged according to a generatrix of this surface other than the generator defining the joint ownership of said strips directly juxtaposed between them and of width and vertical orientation substantially identical to those of the optical strips of the front covering screen so as to accentuate the virtual depth of the relief of the covering optics seen from outside the fire.
- the diverging diopters of the intermediate screen produced in very slight withdrawal from the flat and / or radiated surface of the bands of optical appearance regulating the external relief of said screen, are arranged according to a generator of this surface other than the generator. delimiting the joint ownership of said bands directly juxtaposed between them and of vertical orientation substantially identical to that of the optical strips of the front overlay screen but of different width to either accentuate part of the virtual resulting pitch or to locally accentuate the virtual depth thereof in order to simulate lines of separation of various optical zones of the same appearance as those separating the different optical zones of the windows of a neighboring lighting device such as a projector.
- the intermediate screen and / or the covering screen are positioned orthogonally to the horizontal light positioning plane.
- the intermediate screen and / or the covering screen are inclined to the horizontal plane for positioning the light to further mask the righting diopters from the influence of the sun's rays radiating from the outside.
- FIGS. 1 and 2 describe a first embodiment of the invention.
- the diverging diopters 3 are each coaxial with a convergence diopter 2 and are dimensioned so as to envelop the whole of the light brush focused by the corresponding convergence diopter and to straighten this brush, comprised between the elementary rays C1- C2, in a beam substantially parallel to the incident rays I1-I2.
- the diverging diopters 3 are located slightly recessed with respect to substantially vertical bands 4 also formed on the outer wall of the screen 1.
- This screen 1 is, on its outer wall, covered with a layer of opaque material 5 intended to hide from the outside of the light the coloring member (not shown) of the incident beam, when the light is not on.
- the opaque material 5 is interrupted locally opposite the diverging diopters 3 to form passage orifices for the elementary rays i1-i2 originating from these diopters 3.
- the substantially parallel beams of rays thus formed strike a transparent front covering screen 6 which forms the front glass of the fire.
- the inner wall of the screen 6 is provided with substantially vertical juxtaposed strips 7 formed from flat and / or radiated optical elements which transmit rays r coming from the elementary incident rays i1-i2 to the outside.
- the width of the bands 7 is such that their relief is accentuated by the external relief bands 4 of the intermediate screen 1.
- the pitch and the depth of the optical elements of the strips 7 are adjusted to obtain the desired spreading and distribution of the external lighting beam r and to visually adapt to the glass next to another lighting device, in particular d 'a projector or headlight.
- the passage orifices formed in the mask of opaque material 5 are formed by grooves of small width 8 which accentuate the pitch of the strips of optical elements 7 of the covering screen 6.
- the diverging diopters 3 are arranged along generatrices of the intermediate screen 1 distinct from the generatrices delimiting the bands 4 of the screen 1, these bands 4 being directly juxtaposed with one another with a width and vertical orientation substantially identical to those of the strips 7 of the covering screen 6. It is thus possible to accentuate the apparent depth of the covering optics.
- the strips 4 directly juxtaposed between them and substantially vertical have a width different from that of the strips 7 of the cover screen 6. It is thus possible to simulate separation lines reinforcing the resemblance to the ice d 'an adjacent projector.
- the intermediate screen 1 is orthogonal to the horizontal positioning plane H of the light.
- the cover screen 6 can also occupy such an orthogonal position.
- the intermediate screen 1 (FIG. 5) and / or the covering screen 6 are inclined on the horizontal plane H for positioning the light, in order to hide more the dioptres of divergence 3 compared to the grazing solar rays S coming from outside.
