  • this type of LED lighting ensures that only a small part of the room facing side of the acoustic element 2 is covered by the LEDs ,
  • the LEDs can be arranged such that the individual light cones on the veneer do not overlap, so that a uniform illumination is ensured. Alternatively, they may be arranged so that a plurality of light cones overlap such that a uniform illumination of the veneer 4 is ensured.
  • the LEDs 3 can also be controlled differently (different light output). Also, they can be arranged so that desired light patterns arise on the veneer. These patterns can also be controlled by a light control unit, which is located, for example, in the basic unit 6.
  • Fig. 3 shows a side view of the first embodiment of the acoustic sail 1 in the folded position.
  • the hinge is used for hinged attachment of the acoustic sail 1 to the base unit 6. It is not mounted on the edge of the acoustic sail 1 in the illustrated embodiment, but lies on its (the space facing away) top and is moved in the direction of the center of the acoustic sail. Thus, it is arranged for the viewer, who sees the room facing side, hidden.
  • the folding can be useful in particular for maintenance purposes, if access to the side facing away from the room of the acoustic sail 1 is required.
  • the acoustic sail 1 is mounted hinged down along an axis extending parallel to its longitudinal axis by the hinge.
  • another fastening element is arranged on the acoustic sail 1, which is arranged at a distance from the hinge on the acoustic sail 1 (in FIG Fig. 3 shown as a survey at the bottom left of the acoustic sail 1).
  • the fastening means 7 (here the hinge) is attached to the base unit 6. In the illustrated embodiment, it is attached to a side surface of the base unit 6 and opposite to the spatial direction of the basic device 6 final, the space-facing side (spaced in the direction of the ceiling of the lower edge of the side of the base unit 6). This allows a flat contact between the acoustic sail 1 and the Basic unit 6, if the former is folded (in operating position). In this way, a connection of the first air space 9 can be made possible with an air outlet opening of the base unit 6. This can also prevent the view and access to parts lying in the basic device.
  • Fig. 4 shows a side view of a second embodiment of the acoustic sail 1.
  • the second embodiment corresponds in most parts of the first embodiment, so that a description of the identical parts is omitted at this point.
  • the large-area LEDs 3 are inserted into the acoustic element 2.
  • the large-area LEDs 3 may also contain a plurality of individual parts, for example a plurality of individual luminous elements.
  • the term LED is to be understood as meaning all substantially planar light sources, such as, for example, LEDs, OLEDs, LCDs, AMOLEDs, panels with one or more of the aforementioned bulbs, and others.
  • the LEDs 3 can also be placed on the acoustic element 2.
  • the acoustic sail 1 in the illustrated embodiment does not include a veneer. Instead, the LEDs 3 illuminate the room directly. For this purpose, they are attached to the space facing side of the acoustic element 2. However, a veneer may additionally be used if desired, for example the veneer described for the first embodiment. Also, the LEDs 3 can each be covered with a transparent cover plate. This can serve to protect the light units.
  • the acoustic sail 1 of the second embodiment does not include a second airspace. Instead, the air which has passed through the first air space 9 may be discharged directly through the air outlet slots 11, as indicated by the arrows. This allows an even more compact design of the acoustic sail 1.
  • Fig. 5 shows a view of the second embodiment of the acoustic sail 1 from below.
  • two LEDs 3 are in the acoustic element 2 introduced.
  • the two LEDs 3 are arranged symmetrically on the rectangular acoustic element 2.
  • the dark edge around the acoustic element 2 corresponds to the Lucasauslassschlitzen 11 which surround the acoustic element 2 frame-shaped completely in the illustrated embodiment.
  • the air outlet slots 11 There are also other possible arrangements of the air outlet slots 11 conceivable. Thus, for example, they can be introduced at several points of the acoustic element 2, enclose the acoustic element 2 only partially in the shape of a frame, or break through the acoustic element 2 along one or more axes.
  • Fig. 6 shows a side view of the second embodiment of the acoustic sail 1 in the folded position.
  • the same arrangement of the fastener 7 is used on the acoustic sail 1 and the base 6, which has been described above for the first embodiment.
