Definitions

  • the invention relates to a lighting and / or signaling device for a vehicle, and more particularly to a traffic light for a vehicle comprising at least one compartment equipped with a lamp, with an optical system for forming a beam, a screen in front of the lamp and an ice cream outlet.
  • LEDs light-emitting diodes
  • Light emitting diodes being relatively expensive, it has been sought to produce traffic lights using conventional light sources with a lamp but having a "discrete” appearance of light spots, also called “pixels”, similar to that obtained with LEDs.
  • EP 1 149 732 proposes a signal light with a reflector associated with an optical system composed of lenses, and an opaque screen pierced with holes through which the different beams produced by the lenses must pass to give the appearance of mini illuminated beaches.
  • Such an assembly is relatively delicate: a significant portion of light does not pass through the holes and is absorbed by the screen, especially because of manufacturing tolerances. The energy efficiency of such a system is relatively low.
  • EP 0 784 185 proposes a signaling light comprising a substantially point source, a flux recuperator intended to send outwardly an essentially parallel beam, an intermediate screen and an ice, the screen comprising a series of optical cells each comprising, on an inner face , a substantially spherical spreading surface of the light and on an outer face a set of at least two plane facets oblique with respect to a plane of the screen.
  • the object of the invention is, above all, to provide a lamp signaling light which makes it possible to obtain a pixel appearance with good performance. Energy. It is desirable, moreover, that the traffic light remains of simple and economical manufacture.
  • a vehicle signaling light of the kind defined above, is characterized in that the screen is made of a transparent or translucent material, and comprises a set of patterns making it possible to ensure, at the output of said screen, by transmission direct and / or internal reflection, a spatial distribution of light energy in localized, in particular almost punctual, by transferring most of the light energy entering the screen.
  • the screen is made of a transparent or translucent material, and comprises a set of patterns making it possible to ensure, at the output of said screen, by transmission direct and / or internal reflection, a spatial distribution of light energy in localized, in particular almost punctual, by transferring most of the light energy entering the screen.
  • a light source of the incandescent lamp type Preferably there is a light source of the incandescent lamp type. However, it is also possible to replace them with one or more light-emitting diodes (LEDs).
  • LEDs light-emitting diodes
  • Localized areas of distribution of light energy have the appearance of pixels or elementary points. There are therefore illuminated areas that can be clearly separated and spaced from each other.
  • the set of patterns is advantageously constituted by the repetition according to a determined geometric disposition, for example hexagonal (in honeycomb) or matrix, of an elementary pattern.
  • the patterns are contiguous, to have the maximum optical efficiency, but it is also possible to provide zones between the patterns that do not have the optical properties of said patterns.
  • the elementary pattern advantageously has the shape of a funnel delimited, on the outlet side, by a substantially frustoconical surface of revolution of axis parallel to that of the light beam, which is connected by its small base to a protruding cylindrical coaxial pin forward, this funnel being delimited on the side of the entrance by a stepped meridian revolution cavity, preferably substantially at right angles, favoring total reflection.
  • the cavity of revolution may comprise a central cylindrical portion whose bottom is orthogonal to the direction of the beam to allow direct transmission, the open end towards the rear of this cavity being followed by a first annular surface orthogonal to the direction of the beam then by a cylindrical surface of larger diameter than the central part, opening on the rear face of the screen.
  • the fire can include a style screen pierced with holes to receive the ends of the pawns, this style screen hiding the patterns behind it.
  • this style screen hiding the patterns behind it.
  • the ends of the pins protrude on the style screen.
  • the front end of a pin is advantageously provided with at least one pattern, of the torus type, suitable for ensuring the spatial distribution of the outgoing light.
  • the signal light comprises a collimator system capable of forming a pseudo-collimated luminous flux, that is to say parallel or substantially parallel, collected by the rear part of the screen.
  • the collimator system preferably comprises a Fresnel lens, or alternatively a parabolic reflector.
  • the material used for the screen may be PMMA (polymethyl methacrylate) or PC (polycarbonate) depending on the thermal stresses.
  • the screen can have a circular or rectangular shape depending on the style sought. It can be plane or in three dimensions, in particular with sliding of each elementary pattern parallel to the direction of the light beam to obtain apparent outlets, corresponding to the ends of the cylindrical pins, distributed in space for example along a surface parallel to the ice of exit.
  • the inclination of the generatrices of the frustoconical surface of a pattern is chosen so as to ensure total reflection.
  • the ratio of the input diameter of a pattern to the output diameter is preferably of the order of three to five, preferably of the order of four.
  • the input diameter of a pattern may be of the order of 15 to 25 mm, especially 20 mm while the output diameter may be of the order of 3 to 10 mm, in particular 5 mm.

  • a traffic light A for a vehicle comprising at least one compartment C equipped with a lamp L, with an optical system S to form a beam, a screen E in front of the lamp and an exit glass G.
  • the output ice G is generally transparent. Although this element is called “ice” it can be made of a transparent or translucent material other than glass.
  • the optical system S is constituted by a Fresnel lens 1 which collects the luminous flux of the source L along a solid angle of maximum amplitude, including in the axial direction.
  • the midpoint of the filament is substantially at the focus of the lens 1.
  • the Fresnel lens 1 provides at the output a pseudo-collimated beam 2 with radii such as 2a, 2b parallel or substantially parallel.
  • the Fresnel lens 1, or an equivalent optical element, traversed by the light beam constitutes a primary screen.
  • the light source may be filament lamp type, the least expensive. But it can be replaced with one or more light-emitting diodes, especially in the case where the light source is associated with the Fresnel lens 1.
  • Using light-emitting diodes as light source has advantages: we can then afford to use exit glasses G "crystal", that is to say not colored, since the color of the fire can be obtained directly by the appropriate choice of the diode: one can obtain fires said in "Californian” version , that is to say all white.
  • light emitting diodes being "cold” and heat resistant compared to conventional filament lamps, we can reduce the distance between the diodes and screens, and indeed get very compact lights in depth.
  • the screen E is a concentrator screen, crystal or colored, in a transparent or translucent material. It is constituted by a set of patterns 3 making it possible to ensure, at the output of the screen, by direct transmission and / or by internal reflection, a spatial distribution of the light energy in localized zones 4 that are almost punctual, having the appearance pixels or elementary points.
  • the screen E is located inside the light A and is illuminated by the luminous flux 2.

  • the frustoconical surface 5 is connected, by its small base, to a coaxial cylindrical pin 6 projecting towards the front whose front end, orthogonal to the axis of the surface 5, constitutes the localized zone 4.

  • the cavity 7 (see FIG. 5) comprises a cylindrical central portion 7a whose bottom 7b is orthogonal to the axis of the pattern and to the direction of the beam 2, to allow direct transmission as illustrated for the light beam 2b in FIG. 1.
  • the open end towards the rear of the portion 7a is followed by a first annular surface 7c orthogonal to the axis of the pattern 3, then by a cylindrical surface 7d of larger diameter than the central portion 7a, opening on the rear face of the screen E.
  • the front end of the pin 6 is orthogonal to the axis of the pattern 3 and is advantageously provided with at least one and preferably several patterns 8, of the torus type, suitable for ensuring the spatial distribution of the outgoing light.
  • the input diameter De (Fig.6) of a pattern 3 may be of the order of 20mm, while the output diameter Ds, corresponding to the diameter of the cylindrical pin 6, is of the order of 5mm. More generally, the ratio between the input diameter De and the output diameter Ds is of the order of four (for example between 3.5 and 4.5, in particular between 3.8 and 4.2).
  • the patterns 3 can be organized in honeycombs, the centers of the patterns of two successive rows being shifted so that one obtains a hexagonal configuration of the centers.
  • the pitch of the patterns that is to say the distance between two neighboring centers, is then 17.3 mm with the numerical example of dimensions of the previous pattern 3. We can adopt a matrix organization of the motifs with the centers aligned on rows and orthogonal columns between them; the pitch of the patterns is then 14.1 mm with the same numerical example of dimensions.
  • the screen E may be circular in shape as illustrated in FIG. 7 or of rectangular shape or other, depending on the desired style.
  • the screen E is molded in one piece, the material used may be PMMA (polymethyl methacrylate) or PC (polycarbonate) depending on the thermal constraints.
  • the color of the primary screen constituted by the lens 1
  • each element 3 can be slid parallel to the direction of the light beam to obtain apparent outlets distributed in space, for example along a surface parallel to an outlet window G inclined with respect to the vertical.
  • Fig.10 shows the back of a screen E whose elements 3 have undergone such sliding leading to a three-dimensional version.
  • a B style screen consisting of an opaque plate having holes distributed to receive the pins 6 is advantageously provided to hide the concentrator screen E. Only the front ends of the pins 6 (Fig.8), through which the light can come out, are visible. These front ends of the pins 6 can project on the screen B to improve the lateral vision. Alternatively, the front ends are flush with the surface of the screen B.
  • FIG. 6 shows a section of a pattern 3 and illustrates the management of the light and the behavior of the light rays inside the screen E.
