  • the invention relates to traffic lights which generally include a series of lamps corresponding to the different functions, said lamps being hidden by an external plastic window transparent.
  • the present invention relates to a fire of the type comprising a lamp, a reflector, a screen arranged in front of the lamp and a mirror, the latter comprising a series of colored bars parallel to section substantially rectangular, integral with a thickness of material transparent plastic, sparing between each pair bars of intervals, while the screen shows one flat side and, on the other side, a clean optic to channel the light rays emitted by the lamp towards the intervals.
  • the fire has a uniform appearance and can nevertheless perform all functions, flashing, light reversing, stop, etc ...
  • the invention relates to a fire of the above type defined whose outer surface extends in order to extend laterally, for example, on the side of the vehicle without however departing from regulatory compliance in force.
  • One of the aims of the invention is to achieve a fire whose part extending laterally the ice is lit without the need to provide additional means of lighting which are very difficult to be housed in the vehicle structure.
  • the invention relates to a signaling light for motor vehicle of the type comprising a lamp, a reflector, a screen arranged in front of the lamp and a glass arranged in front of the screen and which has a series of colored bars parallels of substantially rectangular section, integral of a transparent plastic thickness while sparing between each pair of bars of the intervals, while the screen has a flat face and, on the other front, an optic capable of channeling light rays emitted by the lamp at intervals, said fire being characterized in that the glass has an extension intended to extend laterally along the vehicle, the screen having a corresponding extension, said extension of the screen presenting, on its turned side on the side of the lamp, a series of longitudinal ribs one end of which, facing said lamp, has an optical input surface, means being provided to diffuse the light from the side of the screen turned opposite the mirror and in line with the ribs.
  • the means to let pass the light on the side of the face of the screen turned opposite ice and the ribs are formed by a frosting of bands corresponding to the ribs.
  • the optical input surface is formed by a bevel oriented towards the light source.
  • the face of the extension of the screen, turned opposite the lamp comprises a series of convex gadroons, the ribs extending parallel to the right of the junction convex gadroons.
  • the face of the extension of the screen, turned opposite ice has a series of convex gadroons, the ribs being located at the junction of the gadroons.
  • the face of the extension of the screen turned opposite ice, has a series of cylindrical gadroons concave, the ribs being located at the junctions concave cylindrical gadroons.
  • the side of the extension of the screen turned opposite the lamp comprises a series of concave cylindrical gadroons, the ribs being located at the junctions concave cylindrical gadroons.
  • the series of longitudinal ribs have a height which decreases from the entry surface optical to the free end of these, the face said ribs extending the optical input surface being covered with a layer of a diffusing product.
  • the diffusing product plays the role of a series of reflective lenses and the light can pass through the screen without it being necessary to produce frosted bands given the amplification of the light intensity generated by the layer of said diffusing product.
  • Figure 1 shows schematic perspective a fire according to the invention.
  • Figure 2 is a sectional view along the line 2-2 and on a larger scale of the fire of figure 1.
  • Figure 3 is a sectional view along the line 3-3 in Figure 1.
  • Figure 4 is a sectional view along the line 4-4 of figure 3.
  • Figure 5 is a corresponding sectional view in Figure 4 of an alternative embodiment.
  • Figure 6 is a corresponding sectional view in Figure 4 of an alternative embodiment.
  • Figure 7 is a corresponding sectional view in Figure 4 yet another embodiment.
  • Figure 8 is a perspective view of a screen variant.
  • Figure 9 is a sectional view similar to the section of FIG. 3, but aimed at an embodiment using the screen in Figure 8.
  • Figure 10 is a sectional view along the line 10-10 of figure 9.
  • FIG. 1 and 2 shows a socket 1 intended to receive a lamp 2 and a reflector 3.
  • the reflector 3 is masked by a screen 4 which is transparent and which can be, according to the different uses, colorless, or slightly colored, red, green, amber, etc ...
  • the screen 4 comprises, on its face 4a facing the lamp 2, a series of convex gadroons 5, while the opposite face 4b is planar.
  • the screen 4 is masked by a glass 7 which is formed of a series of parallel bars 8 of color which are united, by their face turned towards the outside, of a thickness 9 of a plastic material colorless, a colorless interval 9a being provided between each pair of bars 8.
  • the bars 8 have a section substantially rectangular and in this embodiment extend parallel horizontally but could perfectly be located vertically.
  • the light rays emitted by the lamp 2 are, through screen 4, concentrated in intervals 9a.
  • the intervals 9a are sufficiently narrow so that the observer, located opposite the fire, does not see that a general red appearance when the fire is out, but big enough to let the light through emitted by the lamp 2.
  • screen 4 is colorless and lamp 2 is white, the light passing through the intervals 9a will be white. If you want to obtain a colored light, screen 4 or the lamp 2 will be colored.
  • the glass 7 is provided with an extension 17 which is intended to extend on the side wall of the vehicle, the screen 4 comprising a corresponding extension 18.
  • the extension 17 of the glass 7 is made in the same way as said ice with a series of bars 8 red parallels which are united by their face facing the extension 18 of the screen 4, of a thickness 9 of colorless plastic, a colorless gap 9a being formed between each pair of bars 8.
  • the extension 18 of the screen 4 presents, on the face 4a, a series of convex gadroons 5 and the face 4b facing the ice is flat.
  • the extension 18 of screen 4 has a rib 20.
  • Each rib 20, on the side of its end facing lamp 2 has an entry surface optic which can be formed by a bevel 21 in order to capture as much light as possible from said lamp 2.
  • All the faces of the ribs 20 are perfectly polished to retain light entering through the bevel 21.
  • the bevels of the different ribs can have different inclinations, depending on their position relative to the lamp 2.
  • the part of the face 4b of the extension 18 of screen 4 has, at the right of each rib 20, a frosted strip 22.
  • these strips comprise a frosting which increases from the end of the extension 18 adjacent to a bevel 21 to its end free.
  • the light captured in the ribs 20 will escape through the corresponding frosted strip so that the extension 17 is lit all over its length.
  • FIG. 5 a variant has been represented. of realization in which the screen 10 which corresponds to the extension 18 of the screen 4 present, on its face 10b, turned opposite the extension 17 of the ice 7, a series of convex gadroons 11, while the face opposite 10a facing the lamp is flat and comprises a series of ribs 20a parallel to each other, the interval between the gadroons 11 and located to the right of the ribs 20a being formed from a frosted strip 22a.
  • the frosting is increasing from the bevel 21 to the free end of the ribs. Light captured through the ribs 20a will escape through the strips frosted and will cross the intervals 9a.
