Definitions

the present invention relates generally to the signaling lights of motor vehicles, and more particularly relates to a new signaling light emitting a signaling beam of a certain color and having, when it is extinguished and observed from the outside , a different color, and ensuring if necessary a catadioptric function with a different color from that of the beam.
the first known technique consists in equipping the light with a transparent sight glass 10 alternately comprising bands 11 transparent to radiation and bands 12 opacified on the inside by a coating 13 (applied by screen printing or other) with the desired color.
a transparent sight glass 10 alternately comprising bands 11 transparent to radiation and bands 12 opacified on the inside by a coating 13 (applied by screen printing or other) with the desired color.
the plastic material of the sight glass is colorless and the coating of the strips 12 is red on the outside.
the coating 13 on the interior side is given a neutral color, for example white.
FIG. 2 A second known solution is illustrated in FIG. 2. It consists in providing an ordinary sight glass 20, for example of red color, and inside the sight glass, an intermediate plate 21 forming a filter, the filtering characteristics of which are such that the light passing through the plate 21 then the indicator 20 is white. On the contrary, when the extinguished fire is observed from on the outside, it has the appearance of indicator light 20, i.e. red.
the indicator is transparent and equipped with retro-reflectors arranged in strips, by adding translucent material colored, for example red. And one associates with the sight glass a transparent interior counter-plate which comprises, in line with the retro-reflecting bands, bands of opaque material also added.
the structure thus obtained is complex and costly, since the light must include a sight glass and a counterplate both made with the addition of material (for example by overmolding).
Document FR-A-2 597 191 also discloses a signaling light in accordance with the preamble of claim 1.
the present invention aims to overcome the drawbacks of the prior art and to produce a signaling light which, while being easy and economical to manufacture, leads to the results targeted in the introduction with satisfactory quality.
a signal light 30 which includes areas such as strips arranged alternately and formed by two different plastics extending over the entire thickness of the light.
the sight glass is preferably produced by bi-material molding, for example with a multicolored press.
the indicator On its outer face 33, the indicator is generally smooth, in accordance with the regulations.
First strips 31 are made of a first transparent plastic material, colored or not, and each have on the inner side surfaces 31a intended to ensure spreading, horizontally and / or vertically, of the incident radiation. They may in particular be streaks or a series of spherical or toric balls, in a manner known per se.
Second strips 32 are made of a second transparent plastic material, colored or not but of a different shade from that of the first strips. They have interior surfaces capable of ensuring total or almost total reflection of the incident radiation from the light source.
these interior surfaces are trihedral triangles 32a, so that the zones 32 provide, by triple total reflection, a catadioptric retroreflection function.
the quantity of radiation which passes through the second bands 32 is small compared to that which passes through the bands 31, and in practice is sufficiently low so that the regulatory requirements as regards colorimetry can be satisfied.
the majority of the luminous flux leaving the indicator light is that which has passed through the first bands 31 and which has, if necessary, adopted the uniform shade provided by these bands.
the visual impression for the observer results from the juxtaposition of the alternating bands 31 and 32, the overall tint being typically different from the tint of the radiation emanating from the indicator when the light is on.
the light produced by the lamp can also be tinted, for example by equipping this lamp with a colored bulb, so that the final color of the radiation leaving the fire results from the crossing of one part of the bulb and the other of zones 31.
zones 32 are not catadioptric elements, but so-called “pseudo-catadioptric" elements, that is to say having, when the fire is out, an aspect very similar to that of retro-reflectors , without however fulfilling its function.
Such elements can be for example non-trihedral triangles, or cones of angle at the appropriate vertex.
all of the zones 31 have, over the entire extent of the light or of a group of lights, a homogeneous appearance, while circumscribing to a given zone of the indicator the parts of these zones having a real function catadioptric.
the overall tint of the fire when it is extinguished is a function in particular the relative size of the first zones 31 and of the second zones 32. These relative sizes are determined on a case-by-case basis as a function of the desired shade and of the photometric requirements in terms of light emission and retro-reflective reflection when the zones 32 include elements catadioptrics.
FIG. 4 illustrates an alternative embodiment in which, to further decrease the proportion of outgoing rays having passed through the zones 32, an intermediate plate 40 is provided immediately behind the glass, provided, in this case on its inner face, with a plurality of lenses 41, adapted to the geometry of the zones 31 and not the same as these, which may be in the form of streaks, spherical or toric balls, etc.
Each of these lenses 41 has the purpose of concentrating all of the radiation that it receives from inside the light over the entire homologous zone 31, so that the proportion of radiation capable of reaching the interior faces 32a of the zones 32 is practically zero.
This intermediate plate can serve as a protective counter plate for the retro-reflecting elements located in the zones 32, by defining with the indicator a closed and generally sealed space.
