Description

Background of the invention

[0001] The invention relates to an advertising system with the following features: a) A flexible LED film, which can be rolled to a diameter of less than 100 mm and has a large number of individually controllable LEDs; b) A holder for attaching the LED film.

[0002] The invention further relates to a method for manufacturing an advertising system.

[0003] In well-known advertising installations, the shape of the LED films can change relatively easily. Object of the invention

[0004] The object of the invention is to provide an advertising system in which the LED film is held dimensionally stable in the holder. A further object of the invention is to provide a method for manufacturing such an advertising system. Description of the invention

[0005] This problem is solved according to the invention by an advertising system according to claim 1 and by a method according to claim 6. Advantageous embodiments are set out in the dependent claims relating to the previous claim.

[0006] The advertising system according to the invention is characterized in that the LED film is stretched in the holder.

[0007] The tensile stress forces occurring in the LED film advantageously counteract any change in the shape of the LED film within the holder. These tensile stress forces are particularly 1 kN to 10 kN, preferably 3 kN to 5 kN.

[0008] The bracket is preferably frame-shaped. The bracket can be polygonal, in particular rectangular.

[0009] In a preferred embodiment of the advertising system, a keder bead is arranged or formed on the LED film, which is inserted into a keder rail of the mounting. A keder connection is characterized by high tensile strength and ease of handling.

[0010] An advantageous embodiment includes a hollow retaining element attached to the LED film, with a rail of the retaining element passing through it. The rail is preferably part of a tubular frame of the retaining element. The rail can be easily guided through the retaining element, thus facilitating simple installation.

[0011] An advantageous design is one in which the LED film has ring eyelets that are attached to the mounting of the advertising display using springs and / or rubber bands. This allows the mounting to be designed in a particularly material-efficient manner.

[0012] A further preferred embodiment includes a deep black layer of the advertising display surrounding the LEDs. This makes the light emitted by the LEDs particularly visible.

[0013] The LED film can have a flexible base body on which the LEDs are arranged, with a control unit for individually controlling several LEDs also being arranged on the base body.

[0014] The LEDs can be arranged in a matrix and, in particular, can have a distance to the nearest adjacent LED of 1mm to 80mm.

[0015] The LEDs preferably have a distance to the nearest neighboring LED ("pixel pitch") of more than 2mm, in particular more than 5mm.

[0016] The LEDs can be designed in the form of LED modules with multiple color diodes, for example in the form of RGB LEDs.

[0017] The invention further relates to an advertising system with the following features: A) A flexible LED film, which in particular can be rolled to a diameter of less than 100 mm and has a plurality of individually controllable LEDs; B) a housing for mounting the LED film; wherein C) the housing has a disc, in particular transparent, for the indirect or direct mounting of the LED film.

[0018] Such an advertising display constitutes an independent aspect of the invention. The advertising display may have one, several, or all of the aforementioned features.

[0019] The LED film can be essentially parallel to the disc. The disc can be curved, at least in sections. The disc can be in the form of a plastic disc. The disc is preferably made of acrylic glass, polycarbonate, PVC, and / or PETG. The disc can be in the form of an aluminum composite panel ("Alucobond®"). The aluminum composite panel preferably has a plastic disc coated on both sides.

[0020] The LED film can be placed directly on the glass.

[0021] The disc may have recesses in which at least one LED of the LED film is arranged.

[0022] If a deep black layer of the advertising system is planned around the LEDs, the disc can be positioned between the LED film and the deep black layer.

[0023] The disc can be hood-shaped.

[0024] The housing can take the form of a poster display case, a parapet facade strip, or a high-rise sign. Poster display cases are also known as poster stands. Parapet facade strips are typically used on the ends of gas station roofs. High-rise signs feature advertising space on a very tall pole, making them visible from a distance, for example, from a highway.

[0025] A process for manufacturing an advertising structure comprises the following process steps: A) Removing a poster or tarpaulin from an advertising structure; B) Replacing the poster or tarpaulin with the LED film, resulting in an advertising structure according to one of the preceding claims.

[0026] Further advantages of the invention will become apparent from the description and the drawing. Likewise, the features mentioned above and those described in more detail below can each be used individually or in any combination according to the invention.
