Accordingly, these are comparatively very thin plates which are not subjected to mechanical stress, as is the case, for example, with tiles, in particular floor tiles in accessible areas.
  • DE 102005002783 A1 describes an illuminated tile for attachment to a fastening surface with a carrier plate serving as a light source carrier and spacers which are arranged between this carrier plate and the tile plate parallel thereto and form a type of peripheral frame.

  • the power supply is either at 230 volts of voltage through an integrated transformer, resulting in the drawback that it then becomes difficult to realize a desired particularly flat tile construction. Or a low-voltage connection is provided, which then requires an external transformer at the other end of the cable feed to the tile.
  • the object of the invention is to provide an illuminable plate arrangement, in particular in the form of a tile as flat as possible with a low installation depth, which does not require an electrical cable feed and thereby meets the mechanical loads occurring in the case of a tile.

  • Another advantage over many conventional light tiles is that in the light tile according to the invention usually no large-scale frame is required which takes a considerable part of the surface side to complete. Therefore, a largely full-surface light emission is possible.
  • a narrow frame is possibly only used at the edge when using LEDs as light sources in order to cover the bulbs (LEDs or other light-emitting diodes) which feed into the light exit plate there so far that a direct light emission to the surface side is prevented, since this their light as exclusively as possible on the front side, ie in the edge side, the light exit plate to feed, which then has the function of a light guide. Since transformers and cables are omitted and the light is fed in at the front, it is also possible to achieve a very low installation depth.

Optionally, a corresponding accumulator is provided which stores the energy.

Now, when the tile 120 is turned off, the light can pass through the transparent or at least translucent front plate 115 onto the solar elements 118, so that they absorb the received solar energy (or also energy from artificial light), convert it into electrical energy and store it can. Optionally, a corresponding accumulator is provided which stores the energy. If necessary, that is, when the tile is to be illuminated, the bulbs, not shown in Figure 4 are then turned on and get their power from the previously recorded electrical energy, so that no cable feed for the illuminable tile is necessary.
  • the bulbs are arranged so that they emit their light in the front plate 115 in, if possible so that it is uniformly illuminated and emits this light largely over its entire front surface.
  • Light-emitting diodes in particular OLEDs, which may for example be embedded in the plate 115 or may be applied as a layer or in the form of a foil to the rear side of the light-emitting plate 15, are provided as the light-emitting means.

  • a backside ceramic plate 1 19 can also consist of a transparent material, such as glass or plastic glass, or can be completely omitted, so that the tile essentially consists only of the light exit plate with light-emitting layer 112, since this alone may also be used create desired decorative effects or can simply use the tile as a display.

Abstract

L'invention concerne un système de plaque lumineux qui comprend au moins un moyen d'éclairage (11) ou un certain nombre de moyens d'éclairage, ainsi qu'au moins une plaque de sortie de lumière au moins partiellement transparente (15) dont la surface permet une sortie de la lumière. On utilise comme moyen d'éclairage soit au moins une DEL, la lumière étant injectée dans la face frontale de la plaque de sortie de lumière au moyen du ou des moyens d'éclairage, soit au moins une DEL organique, de préférence sous forme d'au moins une couche plane de DEL organiques. On utilise pour l'alimentation en courant du ou des moyens d'éclairage au moins un élément solaire (18) intégré dans le système de plaque lumineux. Selon l'invention, le système de plaque est réalisé sous forme de plaque composite qui comprend au moins une plaque de sortie de lumière (15) et au moins une autre plaque (19) formant un composite avec la plaque de sortie de lumière. La plaque (19) du composite qui n'est pas la plaque de sortie de lumière est au moins partiellement opaque ou présente certaines zones opaques. On obtient ainsi grâce à l'invention un système de plaque lumineux qui peut notamment prendre la forme d'un carreau présentant une structure extra-plate à faible profondeur d'installation et ne nécessitant pas d'amenée de câble électrique, tout en supportant les contraintes mécaniques susceptibles d'apparaître dans un carrelage.
