Definitions

  • the present invention relates generally to signaling lights for motor vehicles.
  • It includes a base 10 defining at least one cavity 11, the bottom of which constitutes a generally parabolic mirror 12.
  • a lamp 20 is mounted in the bottom 12 of the base and a LED 30 closes the base at the front (compared to the light emission direction) thereof.
  • the mirror 12 on its surface of the ridges 13 in the form of vertical bands, made by normal projection on its surface of streaks horizontal cylindrical, while sight glass 30 is fitted on its internal surface with cylindrical ridges horizontal.
  • the depth effect is achieved when the bands 13 of the mirror 12 and the streaks 31 of the LED generally have orientation perpendicular to each other.
  • the present invention aims to overcome this limitation of the state of the art and in particular to propose a traffic light which has an aspect of depth regular and uniform even over a larger area than the proper fire cavity.
  • the present invention provides a fire signaling as defined in claim 1.
  • a fire signaling system which includes a base 10 which defines at least one cavity 11, the bottom of which constitutes a mirror 12 by example of the parabolic genre and which receives a source bright such as a filament lamp 20.
  • the fire In front of the base (in relation to the direction lighting), the fire includes an ice or warning light closing 30. Between the sight glass and the base is provided, near constant distance and distance from the sight glass, an intermediate screen 40.
  • the intermediate screen 40 has, in this case on its face interior, convex vertical ridges 41 having preferably all the same width and same curvature, while the indicator light 30 also has, on its inner face, horizontal convex ridges 31 also having preferably all the same width and same curvature.
  • the depth aspect is achieved by the sole presence of the intermediate screen and the indicator, together with the fact that behind these elements, the base has at least a relatively shiny appearance, in preferably being aluminized, independently of the distance between the base and the intermediate screen. So 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 level of a non-functional area 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 streaks 31, 41 are also provided in this region on the indicator and on the screen.
  • the distance between the screen intermediate 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 streaks horizontal and vertical streaks can be different from each other.
  • the screen and the indicator light may include streaks of any orientation as long as the streaks of any of the elements are oriented essentially perpendicular to those of the other element.
  • the streaks LED and screen may be concave. According to one other variant, screen streaks can be expected on the face of it facing the indicator.
  • these trihedrons are organized in bands of two rows of parallel and alternating retro-reflectors with a streak 31 (as illustrated in FIG. 5) or a group such streaks.
  • the intermediate screen 40 is of preferably connected tightly to the level indicator of their edges, so as to form with it an enclosure waterproof protecting catadioptric trihedra vis-à-vis dust, dirt, etc., as required by regulations.
  • FIG. 6 illustrates an alternative embodiment of the Figure 5 in which the streaks 41 of the screen intermediate are replaced by toroids 42, that is to say by elements having a curvature both in horizontal direction and vertical direction.
  • the toroids can have a horizontal step of 3 at 6 mm and a vertical pitch from 6 to 24 mm.
  • the depth effect continues to be assured, 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 there are streaks 31, avoiding at least partially retro-reflecting elements 32.
  • the light output of the fire is improved to the extent that the light that is normally lost (by total reflection or by dispersion horizontal or vertical important) when it arrives on the cadadioptric trihedra is partly recovered.
  • the screen intermediate 40 has on its outer face a colored coating (produced by screen printing, by marking with hot, etc.) as red horizontal stripes 43 alternated with strips 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 shows a pink appearance.
