Definitions

  • the present invention relates to vehicle lights, in particular motor vehicles, having reflex reflector glass (s), and in particular to multifunction lights.
  • a reflector glass has a plurality of parallel strips of retro-reflecting elements projecting from its inner face, as well as a plurality of transparent strips inserted between these strips of retro-reflecting elements. These different bands are generally horizontal.
  • catadioptric elements are understood to mean not only elementary retroreflective optics, such as trihedra forming a prism with total reflection, but also elements which, without fulfilling the catadioptric function, have a general appearance similar to these elementary optics.
  • Such general appearance elements similar to that of elementary retroreflection optics have an aesthetic function. They give a uniform external appearance to the glass on which the retroreflective functions are limited to certain regions of the glass only. Signaling glass with aesthetic retro-reflecting elements have in particular been described in patent application FR-2,589,983.
  • the height of the transparent bands between the bands of retro-reflecting elements is constant in each region of the ice corresponding to a particular function of the fire and is different for each function .
  • FIGS 1 and 2 there is shown schematically a multifunction light comprising a base 1 closed by a glass 2.
  • the base 1 has two cavities 3A, 3B each corresponding to a particular function A, B.
  • At the bottom of each cavity 3A, 3B is arranged a light source 4A, 4B.
  • Ice 2 is of the reflector type. It has a plurality of bands of retro-reflecting elements 5 alternating with transparent bands, referenced by 6A in the region of the glass 2 which is opposite the cavity 3A and by 6B in the region of the glass 2 which is opposite the the cavity 3B.
  • the heights of the bands of retro-reflecting elements 5 are identical for the two regions of the glass 2, which correspond one to function A, the other to function B.
  • the transparent strips 6A and 6B are rows of elementary transparent optics projecting from the inner face of the crystal 2. These elementary transparent optics are for example of the toroid or cylinder type, hollow optics or combinations of these different types.
  • the strips 6A are all of the same height.
  • the strips 6B are also all of the same height, but have a different height from that of the transparent strips 6A. Therefore, the light passage areas correspond to different percentages for functions A and B.
  • An object of the invention is to provide a multifunction light whose reflector glass is of a general appearance without breaking between different regions having different areas of passage of light to their total area.
  • They can also correspond to different lighting zones of the same function; or at least one of these regions can have a purely aesthetic function.
  • the invention proposes, for its part, a multifunction light for a vehicle, in particular a motor vehicle, comprising a base having several cavities and a reflector glass (s) closing said base, the interior surface of said glass having a plurality of bands of retro-reflecting elements between which are interspersed with transparent strips, said glass having at least two reflector-forming zones which have ratios of area of passage of light to their total surface which are different, the dimension of the transparent bands between the bands of retro-reflecting elements progressively evolves from one zone forming a reflector to the other, characterized in that the zones being one below the other, when the fire is in place on a vehicle, the size of the transparent bands between the bands of retro-reflecting elements progressively changes over the entire height of the ice.
  • zone forming a reflector is meant the retroreflective zones and the pseudocatadioptric zones.
  • FIG. 3 has been used for the elements of the glass which are found on the glass in FIG. 2 the same reference numbering increased by 10.
  • the signaling light glass 12 shown in FIG. 3 is intended to replace the glass 2 on the base 1.
  • This glass 12 has a plurality of bands 15 of catadioptric elements between which are interposed strips 16A and 16B of transparent elements.
  • the glass 12 has two regions corresponding to the two functions A and B of the light of FIGS. 1 and 2.
  • the bands 16A are the transparent bands in the region corresponding to the function A; the bands 16B are the transparent bands in the region corresponding to the function B.
  • the height of the bands 15 of retro-reflecting elements is constant over all the ice 12. This height is the same as that of the bands 5.
  • the number of bands of retro-reflecting elements in each of the regions of the ice corresponding to the two functions A and B is also unchanged.
  • the height of the bands 16A and 16B of transparent elements varies according to an arithmetic progression from the upper part of the region corresponding to function A to the lower part of the region corresponding to function B. This progression is chosen so as to keep for each of these two regions has a ratio of area of light passage to total area identical to that of the glass 2 of FIGS. 1 and 2, for the same function.
  • the glass 12 therefore has a continuous appearance, without rupture between the two regions corresponding to the two functions A and B.
  • the light passage surfaces for each of these two functions are also preserved.
  • the signaling light represented in these figures comprises a base 20, which has five cavities 21 to 25 (only the cavities 21, 23 and 25 having been shown in FIG. 5), at the bottom of which are arranged light sources 26 carried by a lamp-carrying element P.
  • the base 20 is fixed in a housing L which the bodywork C presents of the vehicle. Said base 20 is closed by a glass 27.
  • the cavity 23 is a central cavity.
  • the cavity 22 is located laterally with respect to this central cavity 23.
  • the cavity 21 is arranged above the cavities 22 and 23.
  • the cavities 24 and 25 are arranged below the cavities 22 and 23. It is indicated schematically by lines mixed on FIG. 4 the delimitations of these different cavities at the level of the glass 27.
  • the base 20 has laterally with respect to the cavity 23 a part 20a which connects the cavity 21 and the cavity 25, so that the cavities 22 and 23 are surrounded in a U by the cavity 21, this part 20a and the cavities 25 and 24 .
  • the five cavities 21 to 25 correspond to five different functions of the fire.
  • the part 20a is devoid of function.
  • the part of the glass 27 by which it is closed is a part of style.
  • the glass 27 is made up of two parts 27a and 27b.
  • the part 27a closes the central zone defined by the cavities 22 and 23. It is devoid of catadioptric elements, its internal surface being squared by rows of transparent balls.
  • the part 27b has a U shape. It closes the cavities 21, 24 and 25 and also covers the part 20a.
  • the inner surface of this part 27b is squared by rows of transparent balls 27b.i) horizontal alternating with rows of retro-reflecting elements 27b.ii).
  • the rows of retro-reflecting elements 27b.ii) are of constant height.
  • the rows of transparent balls 27b.i) are of a height which advantageously decreases arithmetically from the top to the bottom of the glass. Other progression rules are of course possible for the height of the balls 27b.i). In particular, the height of the balls 27b.i) can decrease geometrically.
  • the transparent surfaces opposite the cavities 21, 24 and 25, which correspond to different signaling functions, are adapted to each of these functions.
  • the glass 27 is therefore a glass which provides several signaling functions, while presenting a uniform general appearance: no break between the different regions of the part 27b of the glass, which correspond to different functions of the light, is visible .
  • the part 27b forming a reflector is made of red plastic material; the transparent part 27a is made of a plastic material of a different color.
