Definitions

  • the present invention relates to the field of lighting for the signaling of motor vehicles. It relates more particularly to a device providing relief to the illumination of traffic lights and / or lighting outside or inside vehicles.
  • the present invention aims to provide an original means for providing an infinite effect to the signaling lighting of motor vehicles.
  • the device according to the invention also makes it possible to add stylistic effects to the traffic signals of the vehicles.
  • a new device for a motor vehicle traffic light comprising at least one LED or other type of light source, comprises an optical assembly of at least a first reflector (R1) constituted by a mirror and at least one second reflector reflector (R1) constituted by a mirror and at least a second reflector (R2) constituted by a semi-transparent mirror, said optical assembly being combined with a curtain diffuser (D1) of transparent material in which a light emitted by at least one LED, while the mirror, the semi-transparent mirror and the curtain have their planes or their mean planes substantially parallel to each other, and while the light transmitted and / or reflected by said optical assembly is transmitted and visible by the observer by the face of said second reflector (R2) opposite that facing the other elements of said optical assembly.
  • D1 curtain diffuser
  • the optical assembly is preferably integrated or integrable in a housing, the general shape of which is preferably that of a slice of cylinder, to constitute a module.
  • Another object of the invention is thus a lighting and / or signaling module for the exterior or interior of a motor vehicle, which comprises at least one device according to the present invention, integrated or integrable into a set including all other necessary functional elements.
  • the second reflector (R2) and optionally the curtain diffuser (D1) are arranged in front of the LED or LEDs.
  • the present invention therefore relates to a device for motor vehicle signaling lights as in claim 1 and in the description which follows.
  • the planes or the average planes respectively of the mirror and (the) mirror (s) semi-transparent (s) are substantially parallel to each other.
  • the planes or the average planes respectively of the mirror and (the) mirror (s) semitransparent (s) between them an angle substantially between 1 and 3 degrees of angle.
  • the spatial variability of the images of the unit lighting sources is thus obtained, providing an even more original style effect.
  • the semi-transparent mirror (R2) can constitute the protective glass of the module. Alternatively, this window is added classically.
  • the outer periphery of the device according to the invention may comprise a shoulder, providing an underlining of the outline of the fire.
  • curtain At the end of the light guide called curtain opposite to that which is equipped with at least one LED, it is possible to provide either a cover to mask the view of the light escaping from the curtain on its periphery, or a return element preferably metal, or else chamfers and / or prisms.
  • the device according to the invention comprises a mirror 1 and a semi-transparent mirror 2, and it comprises LEDs 3 suitably powered and directed to emit in the direction perpendicular to the mean plane of the mirror 1 of the light rays which are partially reflected by the semitransparent mirror 2 and partly transmitted therethrough.
  • the effect of depth changes with the angle of view; multiple reflections are more or less spaced.
  • one or more of the LEDs 3 may be non-existent or switchable, so as to reserve the effects of infinity on the images of the patterns carried by the curtain 4.
  • the device according to the invention provides an infinite number of images of which only 7 to 12 on average are visible by the human eye.
  • the light source constituted by the LED or LEDs illuminating the screen and diffusing therein a distributed light, allows viewing one or more patterns engraved on this screen or included in this screen. It is the light thus diffused which is then subjected to the successive reflections of the mirror 1 and / or the semi-transparent mirrors 2 which provides an image of the aforesaid pattern (s) having a remarkable attractiveness, with an effect infinite.
  • the device according to the invention is mainly intended to serve as a lantern and / or position light and / or stop light and / or flashing light, etc., depending on the case both at the rear and at the front. cars. It can also equip an external lighting device such as a side repeater of a vehicle.
