    [0001] The present invention generally relates to a light-signaling device mounted on a motor vehicle, and in particular a vehicle rear light. It is known in the prior art to use light signaling devices with external tinted glass to achieve style effects, as described in US6355723B1 or FR2980425A1. In return, these systems have the particular disadvantage of breaking the visual uniformity, because the outer windows must have light diffusion surfaces that can not be made opaque. JP2005114894-A or US20100149829-A1 disclose internal optical system architectures of light-signaling devices, but here again these optical systems will be visible from the outside and will give a heterogeneous exterior appearance to the light-signaling device. , and especially if the outer ice comprises opaque parts, tinted in the mass for example. An object of the present invention is to meet the drawbacks of the prior art documents mentioned above and in particular, first of all, to propose a light-signaling device with an outer mirror with opaque parts, and of which the internal parts merge from the outside with the opaque parts of the outer ice. For this purpose, a first aspect of the invention relates to a vehicle light signaling device comprising: at least one light source arranged to emit a signaling light when it is lit, at least one outer glaze with a diffusion surface of the signaling light, the outer glass comprising an opaque surround of the diffusion surface, - a housing comprising at least one chamber in which said at least one light source is arranged, characterized in that said at least one chamber is arranged to to give the diffusion surface the same external appearance of color as the opaque surround, when said at least one light source is extinguished. The diffusion surface will be easily confused with the opaque surrounding of the outer ice, since the chamber, which is the theoretically visible inner part of the outside, will give the diffusion surface the same color aspect as that of the opaque surround. . Advantageously: the opaque surround has a predetermined color, said at least one chamber comprises internal walls, and the internal walls have the same color as the predetermined color of the opaque surround. For example, if the opaque surrounding is black, then the inner walls of the room will also be black. Advantageously, the opaque surround has two predetermined chrominance parameters al and bl according to a CIE model L * a * b, and the inner walls have two chrominance parameters a2 and b2 according to the CIE model L * a * b each included in a range of ± 10% of the two predetermined chrominance parameters al and b1, respectively. The CIE model L * a * b (otherwise called CIE color space L * a * b) is well known for color measurement, with: - the L * component, which is luminance or brightness, which goes from 0% (black ) 100% (white); - the component a * which represents a range of 600 levels on the red axis (+299 positive value) towards the green (-300 negative value) passing through the gray (0); - the component b *, which represents a range of 600 levels on the yellow axis (+299 positive value) to blue (-300 negative value) through gray (0). It is also possible to consider giving the internal walls the same colors as the opaque surround according to the RAL coding.
    [0002] Advantageously, said at least one chamber is arranged to limit a reflection of external light rays incident on the outer ice. This implementation limits the reflection to the outside of light rays coming from outside the chamber: we will not see the interior of the room from the outside. Two sub-functions can be mentioned here: the chamber can limit reflection by absorbing radiation (including dull walls for example), or limit reflection and prevent external radiation from entering the chamber. Advantageously, said at least one chamber comprises opaque walls which form a mask coming opposite the opaque surrounding of the outer ice. The mask resumes the contours of the opaque surrounding to define a guide channel of the signal light, whose light passage section corresponds to the diffusion surface. The light radiation from other diffusion surfaces of the outer ice, or other light sources of the signaling device can not enter the room. Advantageously, said at least one chamber comprises internal walls which have a luminosity L less than 20% according to a model CIE L * a * b. One can for example choose matt walls that do not reflect light or little. Note that even if the walls of the chamber are dull, it will not affect the brightness of the outer surface of the outer ice which may have a uniform brightness between the opaque surround and the diffusion surface. Advantageously, the light signaling device comprises an optical system arranged between said at least one light source and the diffusion surface, for transmitting to the diffusion surface the signaling light emitted by said at least one light source, and said at least one light source. a chamber includes an opaque box that surrounds the optical system. This implementation allows to deport and hide the light source. Advantageously, the optical system comprises a translucent light guide. Advantageously, the light signaling device forms a rear vehicle signaling light.
    [0003] A second aspect of the invention is a motor vehicle comprising at least one light signaling device according to the first aspect of the invention. Other features and advantages of the present invention will emerge more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawings, in which: : - Figure 1 shows a rear view of a light signaling device according to the invention; FIG. 2 represents a sectional view of the luminous signaling device of FIG. 1. FIG. 1 represents a rear view of a light-signaling device according to the invention forming a vehicle rear lamp. Only an outer ice 10 is visible. This outer ice 10 is partially dyed in the mass to form an opaque surround 11 which is black, and shown hatched to leave Figure 1 readable. It is conceivable to obtain this opaque surround 11 by a hue in the mass, but also by an opaque coating sticker or by deposition under vapor phase under vacuum for example.
    [0004] The opaque surround 11 defines three free zones of the outer ice 11 which can let through the light. Two first zones 50 and 60 are perfectly distinguishable from the opaque surround 11, but a third zone forms a diffusion surface 20 that the invention aims to make similar to the opaque surround 11. Indeed, the purpose of the It is an object of the invention to provide the outer glaze 10 with a uniformly colored exterior appearance between the opaque surround 11 and the diffusion surface 20, as shown by the hatches in FIG. 1 which are similar between the opaque surround 11 and the surface. of diffusion 20.
    [0005] FIG. 2 represents a section of the light-signaling device of FIG. 1, along the axis II-II of FIG. 1. A light source 51 is arranged in a chamber 52, for diffusing a signaling light through the zone non-opaque 50. This may be for example a reversing light or fog light. Similarly, a light source 61 is arranged in a chamber 62, to diffuse a signal light through the non-opaque area 60. This may be for example a stop light or red rear light. Between the chambers 62 and 52 is a chamber 22 which contains a light source 21 and a light guide 25 which is arranged to transmit to the diffusion surface 20 the signaling light emitted by the light source 21. As explained above, the diffusion surface 20 is translucent and non-opaque, so one could see from the outside the inside of the chamber 22, even when the light source 21 is off. To avoid this, and to give the diffusion surface 20 the same external appearance of color as the opaque surround 11, the invention provides means for preventing all the interior space of the chamber 22 from emitting light radiation when the light source 21 is off. In other words, it is to prevent the chamber 22 from reflecting light rays coming from outside. Firstly, to prevent the chamber 22 from receiving light rays, the chamber 22 comprises a matt black mask 23 which follows the contour of the diffusion surface 20 and forms a channel for the passage of signal light of the same section as that of the diffusion surface. The mask 23 is arranged against the inner face of the outer mirror 10 (with mounting adjustments close), and thus prevents penetration of the chamber 22 from the surface 50.
    [0006] Then, the inner walls of the chamber 22 are made of matt black materials, which have the same color as the opaque surrounding 11 of the outer ice 10. Thus, an incident ray i2 that would pass through the diffusion surface 20 and by the light guide 25, will be absorbed by the inner wall of the chamber 22, formed here by an opaque box 24 which surrounds the light guide 25. Thus, by preventing penetration of the light rays i1, and out of the light rays i2, the invention provides a signaling device whose diffusion surface 20 is merged from the outside with the opaque surround 11.
    [0007] The effect is obtained on the one hand when the opaque surround 11 and the inner walls of the chamber 22 have the same color, by measuring these colors with for example a KONICA MINOLTA CR-400 or CR-410 colorimeter, for example. The colors are declared identical if the opaque surround has two predetermined chrominance parameters al and! D1 according to a CIE model L * a * b, and if the internal walls have two chrominance parameters a2 and b2 according to the CIE model L * a * b each within a range of ± 10% of the two predetermined chrominance parameters al and b1, respectively. On the other hand, the effect is also obtained, when the chamber 22 does not reflect the incident light rays i2 (or if they are able to pass), if the internal walls have a brightness L less than 20% according to a CIE model L * a * b. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the various embodiments of the invention described herein without departing from the scope of the invention defined by the appended claims.
