Problems solved by technology

[0009] However, devices of this type are now installed in high-end motor vehicles due to their particularly high costs, especially because they comprise a large number of light-emitting diodes and the production requires special attention to the optical complexity of the screen.

Embodiment Construction

[0034] figure 1 A signaling device 1 according to a first embodiment of the invention is depicted, said signaling device being mounted in a lateral housing provided at the front or rear of a vehicle, not shown.

[0035] The device 1 is arranged to emit colored signal light in a substantially horizontal direction towards the front or the rear of the vehicle, depending on its position on the vehicle.

[0036] The signaling device 1 comprises in a housing 2 a filament bulb 3 emitting light 4 , a reflector 5 for the light 4 , a cover 6 covering the bulb 3 and an output screen 7 .

[0037] The bulb 3 is here an incandescent bulb of type P21W mounted on a support plate 8 forming the rear of the housing 2 , the filament here oriented along the optical axis XX' of the signaling device 1 .

[0038] The output screen 7 forming the front of the housing 2 is made of a colored or colorless transparent thermoplastic material, such as polymethylmethacrylate (PMMA).

[0039] The reflector 5...

Abstract

The present invention relates to a light signalling device comprising a filament light bulb (3) mounted on a support (8), a reflector (5) consisting of a frustoconical wall extending, widening, from the support (8) towards an outlet screen (7) and at a predetermined flare angle (α) with respect to the optical axis (&KHgr;-&KHgr;') of the device, a shield (6) enveloping the light bulb (3) and contained inside the volume defined by the frustoconical wall; the shield (6) comprising a lateral wall (6B) having a plurality of strip-like through-openings (10, 11, 12) arranged one above the next, these openings allowing corresponding beams (4B, 4C, 4D) of rays of light (4) emitted by the bulb (3) to pass through the shield (6) and be reflected towards the screen (7) by the frustoconical wall of the reflector (5) thereby forming light images that are contained inside one another in such a way as to generate a three-dimensional visual effect.

Description

technical field [0001] The invention relates to a signaling device, in particular a position light located at the front or rear of a vehicle, which is capable of producing a three-dimensional depth effect. Background technique [0002] European application FR2954457A1 describes a device. Such a device comprises a housing comprising a support on the periphery of which is arranged a set of light emitting diodes forming a generally rectangular shape. The device also includes a planar screen positioned above the bracket, the planar screen including a central semi-reflective portion and a transparent peripheral portion. [0003] A reflector having a convex reflective outer surface is disposed between the support and the screen, the reflector comprising a set of openings arranged to the right of the LEDs along their main axis of illumination. [0004] The screen and reflector form a cavity substantially bounded by the reflective outer surface of the reflector and by the inner su...
