Definitions
- the present invention relates to a signaling device for a motor vehicle, comprising one or more light screens uniformly illuminated.
- An organic electroluminescent diode or EO diode consists of a substrate, two electrodes for injecting charges of opposite sign and an organic layer interposed between the electrodes.
- the EO diode emits light when the electrodes pass a sufficient electric current into the organic layer. At least one electrode must be transparent for the light to diffuse outside.
- the electrodes are supplied with current via electrical connectors arranged at the periphery of the diode EO. Electrical connectors are usually concealed behind a mounting frame of a certain thickness and surrounding the EO diode. The position of the electrical connectors or the presence of the Fixing makes their arrangement difficult to form a single and continuous luminous surface.
- the homogeneous illumination surfaces obtained from the EO diodes are generally limited to the dimensions of the EO diode itself.
- EO diodes currently used in the automotive field are limited to a few square centimeters. It is therefore not possible to form homogeneous luminous surfaces of large dimensions and at low costs.
- OLED light sources are much more expensive than light sources with filament bulbs or light-emitting diodes (LEDs).
- LEDs light-emitting diodes
- the small thickness of an OLED diode relative to its light surface makes it particularly vulnerable to shocks.
- the EO diodes are thus very fragile and need to be used with care and precaution.
- the environment of a motor vehicle is not favorable to the use of an EO diode because of the many mechanical stresses, including vibrations and accelerations, and thermal stresses to which its components are subjected. This environment therefore frequently causes failures of embedded lighting devices in motor vehicles using EO diodes.
- the invention aims to solve these defects by providing a signaling device for a motor vehicle comprising at least a bright screen, illuminated homogeneously, larger, more reliable and less expensive.
- the present invention proposes a signaling device for a motor vehicle comprising at least one screen illuminated homogeneously.
- the signaling device comprises:
- a light source configured to emit a light beam whose luminous intensity decreases when approaching the periphery of the light beam; and a screen comprising a first face opposite to a second face, the screen allowing at least a portion of the light beam emitted by the light source to pass;
- the signaling device therefore comprises a means of occultation of a peripheral portion of the light beam emitted by the light source, so that only the portion of the screen illuminated by the center of the light beam is visible by an observer.
- the occulting means does not deflect and / or obscure a central portion of the light beam illuminating homogeneously the second face of the screen.
- the central portion of the light beam is surrounded by the peripheral portion mentioned above.
- homogeneous is meant a luminous surface whose appearance seems uniform for an observer.
- the means of occultation thus makes it possible to hide the parts of the screen perceived by an observer as being of different luminous intensity with respect to the center of the screen.
- a screen can be illuminated homogeneously from a lower cost light source compared to an organic light-emitting diode or EO diode.
- the light source can be a source of light commonly used in the automotive field as a filament bulb.
- the light source is a light emitting diode.
- the light source is oriented so that its light beam directly illuminates the first face of the screen. This embodiment makes it possible to limit the size of the signaling device and to facilitate its integration in or on a motor vehicle.
- the invention thus offers a more reliable and economical alternative to the use of EO diodes in signaling devices for motor vehicles.
- the dimensions of the homogeneously illuminated screen are not limited by the method of manufacturing the light source, as is currently the case for the EO diodes. Indeed, it is easy to change the dimensions of the screen by playing for example on the angle of opening of the light beam emitted by the light source and / or the distance between the screen and the light source.
- the invention also allows the production of light screens of very varied dimensions, in particular of larger dimensions than the EO diodes.
- the light source is placed behind the screen, so that its electrical connectors do not encumber the periphery of the screen as for the EO diodes and can be hidden behind said screen.
- the occulting means comprises an opaque film surrounding the portion of the screen illuminated by the light beam emitted by the light source.
- opaque film is meant that the film obscures the light beam emitted by the light source.
- the opaque film thus makes it possible to conceal from an observer the areas of the second face of the screen that would be perceived as inhomogeneous in intensity.
- the opaque film can also mask a portion of the screen, illuminated homogeneously, so as to define a luminous pattern such as a pictogram, a letter or a number.
- the opaque film is placed in front of the second face of the screen.
- the opaque film is placed in front of the first face of the screen.
- the opaque film comprises an ink covering part of the second face of the screen.
- the signaling device may comprise several opaque films superimposed and movable, so as to form light patterns of different shapes at the screen when the opaque films are shifted.
- the occulting means comprises a sheath present between the light source and the screen, the sheath being arranged to surround the light beam emitted by the light source. so that only a central part of the light beam directly illuminates the screen.
- the sheath is configured so that the most intense portion of the light beam directly illuminates the first face of the screen.
- the sheath is positioned to intercept and / or deflect the peripheral portion of the light beam.
- This embodiment may also make it possible to dispense with the use of an opaque film as described above, while obtaining a similar result, in particular to reduce the size of the signaling device.
- space is meant here a decrease in the depth of the signaling device, the depth being defined in a normal direction or substantially normal to the larger faces of the screen.
- this embodiment makes it possible to illuminate a screen in a homogeneous manner for an observer, by using a light source of less luminous intensity compared with the state of the art. By using a light source of lower light intensity, significantly reduces the size of the light source in the signaling device, including the size of the devices for dissipating the heat produced by the light source. According to another advantage, this embodiment allows also reduce the size of the light source in the signaling device.

- the inner face of the sheath comprises means for diffusing the light beam.
- This embodiment advantageously makes it possible to homogenize the intensity of the beam reflected by the sheath.
- the sheath comprises a distal end, vis-à-vis the first face of the screen, defining a first opening, and the contour of the first opening is concealed behind an opaque film, preferably the opaque film is placed in front of the second face of the screen.
- the outline of the first opening defines an oval or polygonal shape.
- the opaque film delimits a shape identical or similar to the contour of the first opening.
- the sheath comprises a proximal end vis-à-vis the light source and the proximal end defines an oval contour around the light beam.
- the proximal end forms an optical reflector around the light beam.
- the screen is translucent.
- This embodiment advantageously makes it possible to attenuate the variations in light intensity at the level of the second face of the screen.
- the diffusion coefficient of the screen of the light beam decreases when it deviates from the center of the light beam.
- the diffusion coefficient of the screen varies so as to substantially compensate for the variation in light intensity at the second face of the screen when the screen is illuminated by the light beam. This embodiment advantageously makes it possible to attenuate the variations in light intensity at the level of the second face of the screen.
- the signaling device comprises at least two adjacent screens described above, and a control unit for independently turning on or off each light source independently.
- the control unit can be configured to simultaneously turn on several adjacent screens to form a larger bright screen and / or successively turn on multiple screens to create an animation.
- the invention allows the use of a light source of lower light intensity compared to the state of the art, to backlight a screen whose light intensity is perceived homogeneously by an observer.
- a larger overall luminous screen can be formed.
- the depth of the light device does not vary according to the dimensions of the overall light screen. Indeed, the depth of the light device is identical or substantially identical for one or more adjacent screens. Therefore, the invention advantageously allows the realization of global light screens larger areas, perceived uniform luminous intensity by an observer, for a much smaller footprint in depth compared to the state of the art.
- the occultation means comprises a sheath arranged between the source of light and the screen, each sheath being configured to surround the light beam emitted by each light source so that only a central portion of the light beam directly illuminates the screen and in that the sheath is translucent.
- This embodiment makes it possible to create a gradient of luminous intensity around a lit screen, while preserving the homogeneous appearance of the screen in intensity.
- the adjacent screens have their sheath in contact to promote the diffusion of the light emitted by the lit screen into the unlit and adjacent screens.
- the signaling device can display light gradations around one or more lit screens whose intensity is homogeneous.
- the occulting means comprises a sheath arranged between the light source and the screen, each sheath being configured to surround the light beam emitted by each source of light. light so that only a central portion of the light beam directly illuminates the screen, and in that the inner face of each sheath is dark in color, preferably black in color.

- the metallized layer is in contact with the second face of the translucent screen and configured to reflect ambient outside light.
- the metallized layer completely covers the translucent layer so that the elements opposite the first face of the translucent layer are not visible through the screen when the light source is extinguished.
