Definitions

  • the present invention relates generally to signaling lights for motor vehicles.
  • the mirror 12 has on its surface ridges 13 in the form of vertical bands, produced by normal projection on its surface of horizontal cylindrical ridges, while the sight glass 30 is equipped on its internal surface with cylindrical ridges horizontal.
  • the base 10 When the base 10 is metallized or painted with a glossy paint, the combination of the gloss obtained with the cylindrical optical elements of the indicator light makes it possible to "see” inside the light, and gives a so-called “depth” style effect.
  • the depth effect is achieved when the bands 13 of the mirror 12 and the streaks 31 of the sight glass have an orientation generally perpendicular to each other.
  • FR-A-2 427 549 which describes a traffic light in accordance with the preamble of claim 1.
  • the present invention aims to overcome this limitation of the state of the art and in particular to propose a signaling light which has an appearance of regular and uniform depth even over a greater area than the actual cavity of the light.
  • the present invention provides a signaling light as defined in claim 1.
  • a signaling light which comprises a base 10 which defines at least one cavity 11 whose bottom constitutes a mirror 12 for example of the parabolic type and which receives a light source such as a lamp filament 20.
  • the light In front of the base (with respect to the direction of illumination), the light comprises a lens or closing indicator 30. Between the indicator and the base is provided, in the vicinity and at essentially constant distance from the indicator, an intermediate screen 40.
  • the intermediate screen 40 has, in this case on its inner face, convex vertical ridges 41 preferably all having the same width and even curvature, while the sight glass 30 also has on its inner face, convex horizontal ridges 31 also preferably all having the same width and same curvature.
  • the depth aspect is achieved by the mere presence of the intermediate screen and the indicator, together with the fact that behind these elements, the base has an appearance that is at least relatively glossy, preferably being aluminized, independently the distance between the base and the intermediate screen.
  • the aspect of depth is obtained in the case of FIG. 4 not only at the level of the cavity 11, but also at the level of a non-functional zone in which the base 10 has an extension 10 ′ extending close to the screen 40, thanks to the fact that the ridges 31 ′, 41 ′ are identical the lines 31, 41 are also provided in this region on the indicator and on the screen.
  • the distance between the intermediate screen 40 and the indicator 30 is between 0.5 and 3 mm, while the pitch of the ridges 31, 31 'and 41, 41' is between 3 and 12 mm.
  • the steps of the horizontal streaks and the vertical streaks may be different from each other.
  • the screen and the indicator light may have any orientation streaks provided that the streaks of one of the elements are oriented essentially perpendicular to those of the other element.
  • the streaks of the indicator and of the screen can be concave.
  • the streaks of the screen can be provided on the face of the latter facing the indicator.
  • the sight glass comprises not only the streaks 31, but also catadioptric trihedra indicated at 32.
  • these trihedra are organized in strips of two rows of parallel and alternating retro-reflectors with a streak 31 (as illustrated in FIG. 5) or a group of such streaks.
  • the intermediate screen 40 is preferably connected in a sealed manner to the sight glass at their edges, so as to form with it a sealed enclosure protecting the catadioptric trihedra against dust, dirt, etc. ..., as required by the regulations.
  • FIG. 6 illustrates an alternative embodiment of FIG. 5 in which the ridges 41 of the intermediate screen are replaced by toroids 42, that is to say by elements having a curvature both in horizontal direction and in vertical direction.
  • the toroids can have a horizontal pitch of 3 to 6 mm and a vertical pitch of 6 to 24 mm.
  • the depth effect continues to be ensured, while the toroids 42 make it possible to concentrate the light coming from the mirror 12 towards the regions of the sight glass 30 where the streaks 31 are located, at least partially avoiding the retro-reflecting elements 32 .
  • the light output of the fire is improved to the extent that the light which is normally lost (by total reflection or by significant horizontal or vertical dispersion) when it arrives on the cadadioptric trihedra is partly recovered.
  • the intermediate screen 40 has on its outer face a colored coating (produced by screen printing, by hot stamping, etc.) in the form of horizontal red bands 43 alternated with bands without coating.
  • the intermediate screen 40 is tinted yellow-green, while the indicator is tinted pink.
  • the light having passed through the screen 40 and the indicator 30 is amber, while the extinguished fire has a pink appearance.
  • the surface importance of the coating strips 43 relative to the strips without coating is chosen so as to allow a sufficient amount of light flux to pass while giving a shade as marked as possible in the extinct state.
