Definitions
- the present invention relates generally to motor vehicle signal lights, and more particularly a new traffic light presenting a homogeneous appearance when it is off, for example a so-called "deep” aspect, that is to say giving the observer in front of the fire an illusion of great depth of the fire cavity.
- Such a deep aspect light is produced so that classic, by providing on a first element of fire a plurality of relatively wide streaks and radius important, and by planning on a second element of fire or streaks, also relatively wide and of radius important, oriented substantially perpendicular to the streaks of the mirror.
- a disadvantage of this known type of fire is present, despite the aspect of depth, an aspect not homogeneous due to the presence of the lamp, particularly visible.
- the first object of the present invention is to alleviate these disadvantages and to propose a fire comprising such windscreen and therefore the external appearance when it is off has good uniformity of appearance over its entire wide, while possibly presenting an aspect if necessary satisfactory depth.
- the present invention thus provides a fire motor vehicle signage as defined in claim 1.
- the present invention therefore also aims to provide a signaling light having the advantages mentioned above and which also allows, with an exterior color given when off, to generate a beam bright in different shade. This object is achieved by claims 5 and 6.
- a traffic light which includes mainly a filament lamp (not shown), a mirror 1 defined by a fire base and at the bottom of which is formed an opening for the lamp, a windscreen 2 surrounding the lamp and comprising a front face 3, and an indicator 4 located in front of mirror 1 and defining with it a cavity.
- the part 4 can be a screen intermediate, in which case an indicator is further provided exterior, smooth on both sides, to form a so-called fire "fire showcase”.
- the mirror 1 has a base surface 11 which can be a paraboloid or a mathematically defined surface to produce a desired angular distribution of the light beam, and on this base surface are made a plurality of streaks 12 which are in this case oriented vertically to generate or strengthen the horizontal spread of light. These streaks have preferably all the same width in projection and a radius significant curvature.
- the indicator 4 has on its inner face a plurality of ridges 42 oriented perpendicular to the streaks 12 of the mirror, and therefore horizontally in this case these streaks preferably having all the same width, of the same order of magnitude as the width of the streaks 12, and a radius significant curvature.
- Streaks 12 and 42 cooperate to give fire to signaling, off, an aspect of depth.
- the indicator in this example has a tint pink, obtained for example by mixing a material standard red translucent plastic with material colorless transparent plastic in proportions about 20% -80%.
- the translucent windshield 2 has a part of light passage 21, for example generally cylindrical, which is made with a shade chosen so that that in combination with the shade of indicator light 4, we obtain the desired shade for the light beam generated. More particularly, to get a beam basically colorless, corresponding to a reversing light, we tint the windshield 2 in blue. On the other hand, to obtain a beam of amber color, corresponding to a flashing indicator light direction, the lens is tinted green yellow.
- the windshield 2 has a front face 3, visible from the outside, which is designed to blend in as much as possible with appearance from mirror 1 when the fire is out.
- this front face 3 has a concavity similar to that of the mirror, streaks 32 having preferably a width and a curvature close to those streaks 12 of the mirror, as well as properties of reflections close to those of mirror 1. So, if the mirror is produced by vacuum metallization, the face before 3 is preferably also.
- the ridges 32 also cooperate with the striations of the indicator to give the fire an aspect of depth as homogeneous as possible when it is off.
- this front face 3 masks the shade of part 21 of the windscreen, so that the appearance extinguished fire pink, given by the shade of indicator light 4, practically not disturbed by the color of said part 21, which contrasts quite strongly with that of the seer.
- This masking the shade of the windscreen is all the more effective than the base surface 11 chosen for mirror 1 is far from an ordinary dish, for example being designed to ensure by itself a large spread, horizontal and if necessary vertical, light from the lamp.
- Figure 2 illustrates a first variant of realization of the present invention.
- the windshield 2 has an ordinary shape, with a wall lateral 21 generally cylindrical through which passes the light from the lamp towards the mirror, and a vertex 23 generally hemispherical, as well as means 22 wedging behind the mirror.
- the wall 3 'provided with streaks 32 is in this case carried out in one piece with the base which defines the mirror 1, being connected to the region of bottom of said mirror for example by a plurality of branches thin 33.
- This variant is suitable for avoid the black hole phenomena caused when the fire is on, if the front wall of the lens is obscured totally light.
- the coating formed on the front wall 3 or 3 ' can be a semitransparent coating, that is to say having from the outside, when the fire is extinguished, a generally reflective appearance and similar to that of the mirror, but allowing a substantial proportion of light from the lamp to outside when the fire is lit.
- the coating reflective of the mirror can be achieved with the same technical, the difference being that the semi-transparent properties of this coating are not used for the mirror.
