Abstract: An advertising installation has a flexible LED film that is fastened in a holder. The holder exerts a tensile force on the LED film. The LED film is stretched with a tensile stress. The LED film comprises LEDs that can be controlled independently of one another. Preferably, the LED film can be rolled up, wherein the rolled-up LED film has the shape of a hollow cylinder with an inner diameter of less than 100 mm and more than 10 mm.

Abstract: A display device has a display film which has a size of more than 5 m2 and a thickness of preferably less than 5 mm. The display film can include a plurality of LED module each having at least one LED. The display device includes, in particular, a holder for holding a placard of the same size, the holder now holding the display film.

Abstract: A luminous film includes a plurality of light-emitting diodes. The luminous film has micro-optical elements which are arranged in at least one layer. A dedicated micro-optical region with corresponding micro-optical elements can be provided for each light-emitting diode, and the micro-optical elements can have different optical properties within the corresponding region depending on their position. The micro-optical regions can be designed to be structurally identical but differ in terms of optical properties depending on their location on the luminous film. Light emitted by the light-emitting diodes is deflected by the micro-optical elements such that for each light-emitting diode the main emission direction deviates from a surface normal of the luminous film in the region of the corresponding light-emitting diode.

Abstract: A method for producing an LED film with a cut-off edge is disclosed. The LED film has a film with LED pixels arranged thereon. The LED pixels, which each have at least one LED, are controlled via the data line of a daisy chain, which is arranged in a meandering shape on the film. The method provides for a loop of the meandering shape to be severed and for the thereby produced free ends of the data line to be connected or for a loop of the meandering shape to be bridged and for the edge of the LED film to be subsequently trimmed so that the loop is cut off outside the connection remaining on the LED film. Electrode paths of supply voltage lines are preferably arranged in a matrix shape on the LED film.

Abstract: A luminous film has a plurality of light-emitting diodes, a carrier layer and a light-conducting layer having microoptical structures which make it possible to deflect multidirectionally emitted light in a common emission direction of the luminous film, in order to allow uniform illumination of the luminous film surface with a low light-emitting diode population of the luminous film.

Abstract: A lighting system is disclosed for the spatially evenly distributed emission of light from first, second and third light sources. The spectral ranges of the light emitted by the different light sources are different from each other. The lighting system includes: a holding layer or carrier layer, on which the light sources are arranged in groups each having one each of the first, second and third light sources; and a luminophore layer, which is arranged in the propagation direction of the light from the light sources and has a first, a second and a third luminescent-material film. The luminescent material of each luminescent-material film is induced to luminesce largely, more particularly exclusively, by means of the first, second or third light sources.

Abstract: A lighting system for displaying animations, in particular for advertising purposes, has a plurality of light sources, preferably light-emitting diodes. The light sources are held on a base structure. A color layer is arranged on the base structure. The base structure includes a recess for each of the light sources. A controller is configured for actuating the light sources in a synchronized manner in a chronological sequence in order to reproduce the animations.
