It is good to see that the sheet light elements 8 can be changed, that is displaced, rotated and / or tilted relative to their position on the attachment means 6 as well as their orientation relative to the attachment means 6 (that is, either on the wall or sitting on the ceiling).
  • a plurality of flat light elements 8 can be assembled into a larger composite, or can be individually attached to the wall and / or ceiling 6.
  • the light elements 8 can be designed so that they are connected to each other and can be moved, offset and / or rotated as a large area light element 8. Due to their planar shape, the flat light elements 8 can be installed inconspicuously and space-saving on the room walls or the ceiling.
  • a wireless inductive coupling is advantageous.
  • the power supply can be inconspicuous and space-saving installed in the room and it can be inductively coupled via a coil, a voltage in a built-in the flat light element 8 another coil.
  • the best is the power supply behind the wall and / or ceiling 6 and / or is designed flat.
  • the multiple power supplies can each supply one or more light sources 3, or one or more light elements 8. This makes it possible to selectively switch individual lighting elements 8 and / or lighting means 3 on or off and to illuminate the space in a more targeted manner.
  • the power supplies may also be connected to a central controller which performs automatic lighting (e.g., user-programmable). As a result, the illumination may be e.g. automatically adapted to different day and / or seasons.
  • the power supplies could also be controlled via conventional wireless connections from the central control.
  • the light elements 8 may also be provided with light and / or motion sensors or other types of sensors to respond to changing light conditions and / or movement or other changes.
  • the power supplies can be automatically switched on and off or can automatically change the brightness of the lighting continuously. It is also conceivable for each differently colored light source 3 in a light element 8 each provide a power supply to automatically make a color adjustment of the lighting of the lighting device as needed.
  • an inductive power supply is that the flat light elements 8 need not be disconnected from the power supply before they are offset and / or rotated and / or tilted. In addition, they do not require any electrical connections the back, making them easier and better surface to the wall or ceiling 6 are adaptable and also can be made more compact and easier.
  • only one or some of the light elements 8 or light source 3 can be supplied with power via a line, but be designed to inductively transmit voltage to other light elements 8 or light source 3 not connected to the line. It is also possible that only one or a few planar light elements 8 or light sources 3 are supplied with power inductively or via a line and transmit them by touching them to further flat light elements 8 or light sources 3. Thus, the number of power supplies or power line can be kept low and yet all flat light elements 8 and 3 bulbs can be powered.
  • the sheet-like light elements 8 are conductive per se and therefore transmit the current to adjacent planar light elements 8, or that provided conductive paths in the flat light elements 8 conduct the current from a metallic frame to the bulbs 3 and the metallic frame when juxtaposed two or more flat light elements 8 are conductively connected.
  • first and second embodiments described above can be operated by such inductive wireless power supply.
  • the advantages of such a power supply are transferable.
  • the flat light elements 1, 2, 8, the the respective fastening means 4, 5, 6 are mounted, shown as square or rectangular.
  • the sheet-like light elements 1, 2, 8 take any shape, for example, round, oval or polygonal and are not limited in size.
  • a light element 1, 2, 8 is flat when it spans a plane (eg, by the length and width of a rectangular light element 1, 2, 8) that emits light, and whose thickness is smaller than the spread of the plane spanned.
  • a variable lighting device which is suitable for meeting a variety of lighting requirements in a room or building.
  • the invention is characterized in that the planar light element 1, 2, 8 in at least two positions on the fastening means 4, 5, 6 and / or orientations relative to the fastening means 4, 5, 6 can be attached. This makes it possible to easily and quickly change the lighting requirements in a room. These can arise through different distributions of the furniture, different use of rooms or different day and / or seasons.
  • the present invention is also characterized in particular by its high flexibility and its cost-effective production.
