Definitions
- the present invention relates to a motor vehicle signaling light with an intermediate screen.
- the color of a signaling light (typically red or amber) is obtained by tinting the indicator light or the lamp, to color the light rays which pass through it.
- This document describes a signaling light for a motor vehicle, using such an intermediate screen interposed between the indicator and the light source, both colorless.
- This intermediate screen is made of a translucent material, for example red or amber, depending on the function of the traffic light. It has on its outer face bands or other opaque patterns, between which are defined windows for the passage of light rays.
- a set of converging dioptres is placed on the internal face of the screen to converge the light rays emitted by the lamp towards these windows. This ensures spreading of the light beam in a direction transverse to that of the strips.
- Such a light also comprises on the internal face of the sight glass a set of dioptres making it possible to spread the beam in a direction generally perpendicular to the aforementioned first direction, so as to satisfy the regulations as regards photometry and in particular in emission angle material horizontally and vertically.
- the present invention aims to overcome these drawbacks, and to propose a signaling light with colored emission and of neutral appearance when it is off, which reduces the optical work required of the indicator, and which in particular allows the use of a smooth indicator on its two sides, particularly sought after at present by stylists.
- the subject of the present invention is a signaling light for a motor vehicle, of the type comprising a light source, an external indicator, an intermediate screen, placed between the light source and the colorless external indicator, which has on its external surface opaque zones which delimit windows for the passage of light, and first optical elements formed on the interior side of the intermediate screen to converge the light coming from the source and from the flux recuperator towards said windows by giving it spread in a first direction, characterized in that the intermediate screen comprises, on the external side, at the level of at least part of the windows for the passage of light, second optical elements ensuring spreading of the light in a second direction generally perpendicular to the first.
- a signaling light for a motor vehicle comprises a filament lamp 10, a light flux recuperator 30, an intermediate screen 20, and an indicator 40.
- the indicator 40 is made of material transparent plastic, generally colorless, in which case light radiation can pass through it without changing its color.
- the flux recuperator consists of a reflector 30, for example in the form of a paraboloid, the focal point of which is located in the vicinity of the filament 11.
- the intermediate screen 20 consists of a tinted translucent plastic material, for example of amber color for a direction indicator light, or red color for other functions.
- the lamp is colored and the intermediate screen is then colorless.
- first optical elements made up of converging cylindrical lenses 23.
- Each window 22 for the passage of light thus corresponds a lens 23, designed to converge light towards this window.
- the light rays R emitted by the filament 11 or reflected by the reflector 30 are therefore concentrated towards the windows 22 and, at the outlet of the screen 20, therefore exhibit a certain divergence in the horizontal direction, as illustrated.
- the focal point of the converging lenses 23 is situated substantially in the center of the respective windows 22.
- the majority of the beam emitted by the filament crosses the intermediate screen 20, and exhibits at its output a spread in the horizontal direction.
- the intermediate screen prevents a significant proportion of the incident rays 50 coming from the outside from entering the lamp, and likewise prevents a significant proportion of the rays 51 which have entered it and which would be reflected by the reflector 30, to come out.
- the opaque areas of the external surface of the intermediate screen are preferably painted in a neutral shade (white, gray, etc.) or provided with a reflective coating (for example metallized). Thanks to these means, the fire is given a neutral and colorless appearance, and if necessary slightly shiny, when not in operation.
- the intermediate screen also comprises, on its external face and at the level of the light passage windows 22, second optical elements 24.
- These optical elements are preferably produced in one piece with the screen 20, having come from molding, and have the object of ensuring spreading of the beam in a direction generally perpendicular to the direction of spreading provided by the lenses 23, that is to say in l 'species vertically.
- These elements 24 successively comprise a plurality of divergent individual devices whose generator is horizontal.
- the light rays emitted by the filament 11 are spread by means of the first and second optical elements in two substantially perpendicular directions.
- the divergent optical elements 24 are made up of convex horizontal cylindrical lenses, to ensure a uniform spreading of the light in the vertical direction.
- the divergent optical elements 24 are double prisms having in vertical section a shape of an isosceles triangle. In this way, preference is given to spreading the light leaving the screen 22 in two directions inclined respectively upwards and downwards relative to a horizontal direction.
- the optical elements 24 are simple prisms each having a vertical section in the shape of a right triangle. Depending on the orientation of these prisms, we favor a direction of deflection of the radiation, downwards or upwards. In this example, we plan alternating strips of prisms deflecting the light up and down. The prism angles can of course vary as a function of the photometry to be reached.
- the external optical elements 24 are preferably arranged in grooves 25 separating the adjacent opaque zones 21, so as to be flush with or set back from a common plane of said zones 21 In this way, the masking of the windows 22 provided with the elements 24 during the step of coating the zones 21 (for example vacuum metallization) is facilitated.
- the radiation at the screen outlet is spread in two perpendicular directions, this spreading being able to be substantial and making it possible to cover angles reaching 40 ° relative to the axis of the light. Consequently, the optical role of the indicator can be considerably reduced.
- the indicator can be either smooth, or equipped with diffusion elements (beads or the like) very slightly pronounced, which is advantageous both with regard to the cost of manufacturing the indicator and the aesthetic appearance of the fire.
- the intermediate screen can adopt various shapes and various positions in the fire.
- the screen is planar and arranged perpendicular to the optical axis of the light.
- the screen is planar and obliquely disposed both vertically and horizontally relative to the optical axis. This obliquity can be reversed ( Figures 5c and 6c), or exist only horizontally or vertically.
- the screen intermediate is curved, and is connected to the reflector substantially at the transition between the bottom of said reflector and its cheeks.
- the screen has a curve opposite to that of Figures 5d and 6d, adopting substantially the shape of the bottom of the reflector.
- all other forms and arrangements can be envisaged.
