Definitions

  • the invention relates to motor vehicle signaling lights and more particularly to direction change lights.
  • the rear signal lights of a vehicle include a red part corresponding to the indication of braking and an amber part corresponding to changes in direction.
  • the vehicle has only headlights and the amber part.
  • the invention relates to a light which, from the outside, makes it possible to give an impression of unity with the adjoining lighthouse.
  • French patent 2,517,804 has proposed a light for such a purpose and in which, in front of the lamp, there is a network of converging lenses and in front of it a perforated plate having frustoconical perforations and of which the side facing the diffuser carries a reflective layer.
  • the converging lenses must be arranged so as to be aligned with the frustoconical holes and so that, from the outside, the coloring is not visible, it is also desirable that the face coated with a reflective layer is also made up of divergent lenses.
  • Such an arrangement also has the drawback of requiring a reflective treatment of the first screen, which is expensive.
  • German patent n ° 956.566 which describes a rear light of a motor vehicle comprising a retro-reflecting screen with flat surfaces and an intermediate screen arranged between the retro-reflecting screen and the lamp, this intermediate screen having bi-convex lenses to the right of the flat surfaces of the retro-reflecting screen in order to make the light rays coming from the lamp converge towards said flat surfaces.
  • German patent n ° 1 655 784 relates to a signaling light which comprises a first screen arranged in front of an incandescent lamp which has, on its face facing the lamp, a series of concentric grooves and on the other face of the lenses divergent.
  • a transparent screen In front of the screen is arranged a transparent screen which has opaque bands.
  • a transparent screen In front of the screen is arranged a transparent screen which has opaque bands.
  • Such an embodiment has the disadvantage that the screen is expensive to produce and is unsightly.
  • One of the aims of the present invention is to remedy the drawbacks of the prior art.
  • the improvements according to the invention apply more particularly to flashing direction change indicator lights of the type comprising a reflector, an incandescent lamp, a diffuser masking the reflector, means for coloring the light beams coming from the lamp, a first screen for channeling the light beams towards the outside, a second screen for masking, from the outside when the lamp is not lit, the means for coloring the light beams and arranged in front of the first screen, the latter having on its face turned opposite the lamp, a series of concentric grooves and, on at least one of the parts of one of its faces, a network of lenses in the form of spherical caps, said improvements being characterized in that the second screen comprises on its face turned opposite the first screen catadioptric prisms affecting the shape of pyramids having three lateral faces and whose edges adjacent to the base are truncated so as to form between the prisms of the flat surfaces hexagonal, said bases themselves being hexagonal.
  • the coloring is perfectly invisible, while, when it is lit, it has a good intensity.
  • the face of the first screen facing the second screen has the network of lenses in the form of spherical caps, the entire face facing the lamp being covered by the concentric grooves.
  • the concentric grooves are located in a part of the first screen located to the right of the lamp, the rest of the surface comprising a network of lenses in the form of spherical caps, the other face being plane.
  • the concentric grooves are located in a part of the first screen located to the right of the lamp, the rest of the surface comprising a network of lenses in the form of spherical caps, the other face comprising a network of spherical caps.
  • the means for coloring the light beams are formed by coloring part of the surface of the lamp.
  • the light shown in Figure 4 includes a socket 1 intended to be connected to a suitable source of electric current and arranged to receive the base 2 of an electric lamp whose balloon 3 has a cap 4 tinted in amber.
  • the socket is mounted in a silver reflector 5 internally supporting two screens 6 and 7, a diffuser 8 made of transparent plastic being placed in front of the assembly.
  • the screen 6 (see FIG. 2) comprises on the side of the lamp a series of concentric grooves 10, while the other face (see FIG. 1) comprises lenses in the form of spherical caps 11.
  • the light rays emitted by the lamps are channeled outwards.
  • the screen 7 has, on the side of the diffuser 8, a flat face, while on the other side, comprises a succession of catadioptric prisms 13 affecting the shape of a pyramid having three lateral faces and whose edges adjacent to the base are truncated so that said base determines a hexagonal surface, the vertices being turned towards the screen 6.
  • the catadioptric prisms are arranged in order to delimit between them hexagonal flat surfaces 14 parallel to the face turned towards the diffuser 8.
  • the two screens 6 and 7 are made of plastic material with a crystal appearance.
  • the ball 3a of the lamp is either colorless or frosted and there is provided a cap 10 attached to the reflector 5 has and which fits over said lamp .
  • the cap is colored in amber so that the light rays described or reflected by the reflector 5 a and which only pass through the surfaces 14 a are colored.
  • the surface of the screen 6 b facing the screen 7 b comprises a network of lenses 11 b in the form of spherical caps corresponding to the lenses 11 shown in FIG. 1.
  • the face facing the lamp 3 b is at right of the cap 4 b of the concentric grooves 15, while the rest of the surface is provided with lenses in the form of spherical caps 16.
  • FIG. 8 there is shown a last embodiment of the invention.
  • the same references have been used as those used for FIGS. 4, 5 and 6 to designate the corresponding members, but assigned the letter "c".
  • the screen 6 c has, on the side of the cap 4 c of the lamp 3 c, concentric grooves 15 of the same type as those shown in FIG. 7, these grooves extending in line with the cap 4 c of the lamp 3 c , while the rest of the surface is provided with spherical caps 16.
  • the face of the screen 6 c facing the screen 7 c is planar.
  • the screens 6 a , 7 a , 6 b , 7 b and 6 c , 7 c are made of plastic material with a crystal appearance and the same results are obtained with this combination as with the various preceding combinations.
  • the diffusers 8, 8 a , 8 b and 8 c can have lenses on the internal face or the external face to distribute the light according to a desired spatial distribution.
