Definitions
- the present invention relates to signaling, in particular for motor vehicles according to the preamble of claim 1.
- Such fires generally carry out several signaling functions (multi-function lights), such as for example that of the vehicle reversing light, that of the fire direction indication, that of direction indication light vehicle braking (commonly called stop function) or that of fog light.
- multi-function lights such as for example that of the vehicle reversing light, that of the fire direction indication, that of direction indication light vehicle braking (commonly called stop function) or that of fog light.
- such lights include a source of light and flux recovery means suitable for redirect the light flux emitted by the source according to a first overall direction.
- a first screen which has optical elements that make converge the light beam towards bands translucent of a second screen that the latter comprises alternating with colored bands. The second screen is visible from the outside.
- the extinguished aspect of fire is given by the colored bands while the light emitted by the fire is not colored or possibly colored in a different color than the colored bands.
- the object of the present invention is to improve still the extinguished aspect of such a fire.
- it aims to give the fire an even more quenched appearance uniform and even more consistent with the color of the bands colored.
- Another object of the present invention is to give together with what is mentioned above a aspect of depth to fire very appreciated by the stylists.
- the present invention provides a signaling light, in particular for vehicles, according to the claim 1.
- a person of average height whose eyes cannot are not in the axis of a light according to the invention (i.e. according to the first direction) but notably above, will therefore see the colored opaque bands from the first screen to through the translucent bands of the second screen, which will give these translucent bands a colorful appearance when the fire is out. The uniform appearance of the fire is thus significantly improved.
- a signaling light comprises in a housing (not shown) a lamp 6 whose filament 61 creates a light source.
- the reflector 8 re-emits a light beam spread horizontally but not spread vertically, which means that the projections light rays in a vertical plane form a parallel beam, or that the vertical component light rays is zero.
- the recovery means 8 could be as a variant a Fresnel recuperator placed at the front of the lamp 6.
- the fire has a first screen 2 on which lines 21 of optical elements are provided.
- these lines 21 of elements optics are gadroons, i.e. lenses convex cylindrical, which extend on the turned side towards the reflector 8 in a second direction horizontal essentially perpendicular to the first direction. These optical elements therefore achieve the vertical convergence of the light beam re-emitted by the reflector 8.
- the light beam thus modified meets the relevant standards, thanks to successive spreads respectively horizontal by the reflector and vertical by the first screen.
- the lines 21 of optical elements do not occupy not the entire surface of the first screen 2 but are spaced.
- the first screen 2 consists of opaque bands colored 22 which also extend according to the second direction.
- opaque band here means that the light cannot pass through the strip of material according to the first direction and out of the light. These opaque bands are in the example described colored in red.
- the side of the first screen 2 facing outside the light, i.e. forward according to the first direction, is essentially smooth.
- the opaque colored bands 22 are colored reflectors 22a, projecting towards the reflector 8, which therefore reflect the light they receive from outside the fire.
- the bands located between lines 21 optical elements are stamped on their face opposite to reflector 8 while they are smooth on their side facing the reflector 8.
- Marking 22b thus affixed, here in the form of pad printing, makes these bands opaque and additionally gives them color desired views from outside the fire.
- This second screen 4 consists of a alternating translucent bands (colorless in the example described) 41 and colored bands 42. All of these bands 41, 42 extend essentially along the second direction, that is to say essentially parallel to the opaque colored bands 22 and to the lines 21 of optical elements of the first screen 2.
- the translucent bands 41 of the second screen 4, here colorless, are located to the right of lines 21 of elements optics of the first screen 2, so as to transmit without modification of the light beam transmitted by the first screen 2.
- the translucent bands 41 of the second screen 4 are not not colorless but can color the beam emitted by fire.
- the colored bands 42 of the second screen 4 In front of the colored bands 42 of the second screen 4 so we find the opaque colored bands 22 of the first screen 2.
- the colored bands 42 of the second screen 4 and the colored opaque bands 22 of the first screen 2 2 will have advantageously the same color, red in the example described.
- the translucent bands 41 of the second screen 4 have a width significantly less than that of the colored bands 42 of the second screen 4.
- the surface of the second screen facing the outside of the fire is overwhelmingly colored, which further improves the colored appearance (red in the example) extinguishes the fire.
- the invention also proposes to place the second screen 4 at a distance of the order of the focal length cylindrical lenses 21 of the first screen. So the second screen 4 is located approximately at the point of convergence of the light beam and the extent of the bands translucent 41 of the second screen 4 is reduced to a minimum.
- This distance between the two screens 2,4 allows in addition to give the fire an aspect of depth.
- the faces of the colored bands 42 and translucent 41 of the second screen 4 facing the first screen 2 are smooth in this first mode of production.
- the faces of the strips colored 42 and translucent 41 of the second screen 4 tours towards the outside of the fire are covered with a layer 44 made of translucent material, preferably colorless and coming from molding with the translucent bands 41 of the second screen.
- This layer 44 therefore forms the front face 43 of the second screen 4, facing the outside of the light.
- This layer 44 being translucent and colorless, it does not alter the light emitted by fire or its aspect off. However, it simplifies the molding of the second screen 4 since it makes possible the molding of all the translucent bands 41 of the second screen 4 in a single injection. In addition, the strength of the second screen 4 is increased.
- the front face 43 of the second screen 4 is advantageously smooth; the second screen 4 4 can then play the role of closing glass for the fire box.
- a closing glass can be provided separate from the second screen 4 and placed at the front thereof.
- FIG. 4 A second embodiment of the invention is shown in Figure 4. Items similar to the first embodiment are designated in Figure 4 by references identical to those used in the previous figures.
- the bands colored opaque 22 of the first screen 2 are produced by marking as in the variant embodiment shown in Figure 3.
- the faces of the colored bands 42 of the second screen 4 facing the first screen 2 are not smoother but provided with retro-reflectors 45.
- the opacity of the set colored opaque bands 22 of the first screen 2- colored bands 42 of the second screen 4 is still improved.
- the opaque colored bands 22 of the first screen 2 may be carried out by colorless retro-reflectors with protruding parts facing the reflector 8 and the molding of strips of a translucent and colored material on the face of the first screen 2 facing the second screen.
