- pane unit A technical development of such a pane unit is disclosed by the insulating glass unit according to WO 2019 096 872 A1.
- the pane or insulating glass unit disclosed here comprises a plurality of transparent spaced apart
- Layers at least one of which is formed by an illuminable plate.
- An edge of the illuminable plate can be illuminated by an activatable lighting element, or the activatable lighting element can illuminate the edge of the illuminable plate.
- an object of the invention can be seen in providing a variably illuminable pane unit which at least partially avoids the disadvantages mentioned above.
- it can be regarded as an object of the invention to provide a surface luminaire with a homogeneous light field on and / or in a pane unit, which is not
- switched on lighting element can offer a desired level of transparency.
- the invention proposes a pane unit with the features of the independent claim, which comprises a frame construction, which in particular can correspond or resemble a frame construction of a conventional pane.
- the frame construction of the invention comprises a frame construction, which in particular can correspond or resemble a frame construction of a conventional pane.
- the disk unit can be rectangular with a straight line and a right angle
- the pane unit according to the invention comprises at least one illuminable pane.
- the illuminable pane can be carried and / or held by the frame construction.
- the disc unit also has at least one in the
- At least one in particular electrically operated lighting element can be included, which is on and / or in the illuminable disc shines as soon as it is activated.
- the at least one lighting element and its associated receptacle are preferably designed in such a way that the at least one lighting element can provide an at least approximately homogeneous light field on or in the illuminable pane.
- the arrangement or attachment of the at least one lighting element can be placed on and / or along the at least one narrow side of the illuminable pane in the fitted receiving option.

- a particularly interesting appearance for the viewer of the pane unit results in optional design variants in which non-rectangular or round designs of the overall construction are used
- pane unit Another appearance of the pane unit that is particularly interesting for the viewer results in an optional embodiment variant of the invention in which the overall construction is curved.
- the bending radii of the components have to be adapted accordingly. This means that the individual frame segments that normally meet at right angles at their respective ends and thus the corners of the Form disk unit, are not formed in a straight line, but curved or bent, which can lead to desired contours of the frame of the disk unit, which do not result in a rectangular plan.
- the invention comprises a disk unit in which the at least one
- Lighting element can be variably positionable and / or removable in the fitted receptacle on and / or along the at least one narrow side of the illuminable pane.
- a particularly advantageous optional embodiment variant of the pane unit results if at least one lighting element is positioned in the center of the illuminated pane with parallel irradiation to the pane surface, since in this case the light yield of the construction is particularly high.

- Lighting element with variable brightness or variable light color With this option, for example, it is particularly advantageously possible to mount the disk unit
- a wide variety of lighting scenarios for example with make-up mirrors, are shown.
- a particularly advantageous application can also be occupational medical applications, such as the realistic simulation of daylight when working underground.
- the pane unit can also be designed such that the at least one illuminable pane consists of transparent material.
- An advantageous light yield of the construction results, for example, from the use of light-scattering plastic, preferably polymethyl methacrylate, or light-scattering glass, lasered plastic, lasered glass or other light-scattering material.
- the transparent panes enable easy and safe cleaning of the construction.
- a particularly advantageous optional embodiment variant of the invention results when at least one illuminable pane is partially replaced by a transparent pane.
- the light emitted by the lighting elements penetrates the transparent pane with only very little light scattering and then strikes the remaining illuminable pane. This emits the light of the
- Lighting elements then from construction.
- the viewer gets the optical impression of an apparently floating light surface in the form of the remaining illuminable pane. If the division between the illuminable pane and the transparent pane is chosen appropriately, this optional construction makes it possible, for example, to make logos and other representations appear to float in space.
- the use of plastic glasses also results in different refraction and irradiation when compared to mineral glasses
- Embodiments have proven themselves in which the pane unit has an illuminable pane with switchable and / or tintable material and different light penetration conditions can be imaged.

- the illuminable pane is made of plastic
- a design of the at least one transparent pane made of mineral glass is particularly advantageous since the illuminated pane is additionally protected against dusting by electrostatic effects of the plastic.
- advantageous embodiments of the invention can also result if at least one illuminable and / or transparent pane is partially or completely made in special qualities.
- the illuminable and / or transparent pane can also be made of extra light material. This option can be used, for example, as a floor, wall or roof surface in passenger conveyor systems such as elevators to save mass.
- the at least one illuminable and / or transparent pane of the pane unit can be colored and / or opaque over part or over the entire surface.
- a particularly high homogeneity of the color of the light emitted by the illuminated panes can be generated by selecting suitable, high-quality lighting elements.
- at least one of the illuminable panes or one of the transparent panes of the pane unit according to the invention can be designed in whole or in part in color. This option can be generated, for example, in the form of solid-colored illuminated panes or transparent panes, or alternatively by applied films or by lacquering. This enables, for example, the display of images or silhouettes and can be used for artistic design and as an advertising medium.
- the illuminable and / or transparent pane can also be designed in such a way that it serves for the pictorial representation of landscape or street images. This option can be used, for example, to simulate the view from windows.
