12 in the sleeves 8 there is no danger that the tubes 12 could move sideways or actually slip out of the mesh 1 however as a precaution in practice light securing measures should be applied to a pipe this for example can take place on the edge of the mesh 16 for example in that several tubes 12 or their line controllers 17 are attached to a central common power and control connection 18 it is understood that a mesh of the previously described type can be utilized not only in such a manner that it is aligned directly in emitting direction 13 toward a provided viewer location rather it can also emit light in the opposite direction that is towards the fa u00e7ade of the building due to the emitting angle of in particular leds a relatively gap free illuminated picture can be created at a suitable distance from the facade whereby rather sharp contours are also obtained if the viewer maintains sufficient distance from the picture it is naturally also possible to use the invention for producing soft or even blurry light effects such effects can already be created with a less dense grid size in the mesh and are therefore more cost effective to manufacture and maintain the flat ribbon spiral mesh 19 in fig8 and 9 consists of a plurality of line shaped arranged spirals 20 21 22 characterized as an example of metallic ribbon 23 characterized as an example the ribbon 23 is wrapped around per line 24 25 characterized as an example.
