Definitions

  • the invention relates to an image carrier, in particular in the form of a giant poster, of a flat, flexible material with an image-carrying front side and a method for using such an image carrier.
  • Giant posters of this kind are increasingly used in outdoor advertising in recent years. These giant posters are oversized posters, which are attached to scaffolding in particular and achieve a high advertising impact due to their size.
  • giant posters are also used to disguise construction sites, usually displaying the image of the built or renovated property until completion of construction.
  • These giant posters are composed of sheets of several meters wide and held on scaffolding, with overall dimensions in each direction of over 100 meters by an appropriate denomination are easily possible. So the impression can be awakened that a building is already completed, and passers-by take the Baustele, which is usually distracting, less true.
  • the invention has the object, an image carrier of the type mentioned in such a way that it is more flexible.
  • This object is achieved in that a plurality of light-emitting elements is mounted like a matrix on the image carrier and a control device for the common control of the lighting elements in such a way that they show a light image on the front of the image carrier is provided.
  • the invention is therefore based on the consideration to provide a luminous display on the giant poster, the matrix-like arranged light elements is formed.
  • These light-emitting elements can be controlled in a known manner via the control device in order to generate static images or moving images. It has been found that the luminous elements required for the formation of such a light-emitting display can be dimensioned small and, moreover, can be arranged at such a distance from one another that the visibility or recognizability of the image printed on the image carrier is only insignificantly impaired.
  • the embodiment of the invention makes it possible, for example, to use the image carrier in a double manner.
  • the light display is turned off so that the image printed on the image carrier is visible, while images or videos are displayed on the light display in the dark.
  • the possibility is opened to show different advertising in one location and also to use the veils on objects to be renovated, which show the newly renovated building in the night mode for advertising.
  • the lighting elements can also be used during daytime operation in order to increase the effectiveness of an advertisement printed on the image carrier. For example, it is possible to generate a light frame via the light elements.
  • the light elements are attached to the image-bearing front side of the image carrier.
  • the lighting elements are arranged on the back of the image carrier, in which case the image carrier has recesses corresponding to the lighting elements through which the lighting elements can radiate light towards the front side.
  • the lighting elements may be inserted into the corresponding recesses of the image carrier.
  • the entire light emitted by the light elements can be used for the presentation of the light image, since there is no shading by the image carrier.
  • the lighting elements can be attached to the image carrier, so that a simple mounting of the image carrier together with the light elements is possible.
  • the lighting elements can already be attached to the image carrier before the image carrier is mounted on a scaffold or the like. A required wiring can be installed on the back of the image carrier without covering the image carrier.
  • the lighting elements are inserted from the back into the corresponding recesses of the image carrier. This allows after attaching the image carrier to the scaffold easy maintenance and in particular the simple replacement of bulbs, since the scaffold from a complete access to the light elements is possible.
  • the lighting elements can be clipped into the recesses.
  • the edges of the recesses should have an annular reinforcement and the lighting elements should have a corresponding clip device.
  • clipping requires only one-sided access to the image carrier, i. either from the front or the back.
  • connection cables can extend in an extension direction of the image carrier and the lighting elements can be connected to the connection cables at regular intervals.
  • This type of wiring is a particularly simple variant, since the structure is very simple and the amount of cable required is low. In case of possible defects of lighting elements, the identification of the affected lighting element over the course of the connecting cable is easily possible. The regular distances automatically result in the matrix structure required for the illumination image, so that a uniform illumination image is generated.
  • connection cables can be stretched in the direction of extrusion of the image carrier. This increases the local strength of the light-emitting elements and improves the stability of the image carrier itself. At the same time the Handling easier because lighting elements and recesses have the same grid.
  • the lighting elements may be provided on or on at least one holder, wherein the lighting elements of a holder are mounted together on the image carrier.
  • the holder may comprise a frame, are stretched on the light elements with their connecting cables, or struts on which the light-emitting elements are held and positioned.
  • the struts are either held to the frame as part of a module or directly form the support and are e.g. held on the scaffolding.
  • the recesses corresponding to the luminous elements also allow the luminous elements of a holder to be inserted together into the corresponding recesses in the image carrier.
  • the at least one holder consists of a transparent material, in particular Plexiglas.
  • Plexiglas has a high strength with low weight and is particularly suitable for large brackets, which may be dimensioned according to the dimensions of the image carrier.
  • the masking by the Plexiglas is difficult to perceive and the image applied on the image carrier remains clearly visible.
  • the distance of the lighting elements is 10 to 20 cm. By this distance can be achieved based on the total size of the image carrier that the light elements are perceived together despite their distance from each other as a luminous image without affecting the perception of the image on the image carrier during the day.
  • the image carrier may consist of a fabric material, in particular a mesh vinyl.
  • the fabric material has the required flexibility, so that the image carrier is universally applicable.
  • a high strength of the image carrier is achieved by the fabric structure and the wind can easily pass through the fabric material, so that the susceptibility to wind is low.
  • These materials can also be easily printed, which facilitates the application of the image.
  • Each light-emitting element can have at least one individual light which can be controlled in terms of brightness, and the control device can individually control the brightness of each individual light.
  • the control device can individually control the brightness of each individual light.
  • these are operated together in order to control the brightness of a pixel, with each individual luminaire in principle being able to be controlled separately.
  • a light image can be generated whose qualitative impression of a picture alone of black and white luminous points, in which the lights are only on or off, is clearly superior.
  • each luminous element may comprise a plurality of different-colored individual luminaires, each of which is controllable in brightness.
  • the control device can control the composite color of a luminous element by changing the brightness of the individual luminaires. This allows the display of color images, which further increases the scope for the representation of a light image.
  • each luminous element can comprise three individual luminaires in RBG colors. With individual luminaires in these three colors, in principle, any color can be displayed, so that any kind of images can be displayed.
  • combinations of single luminaires are known from many fields and reflect in particular the usual splitting of video signals in single colors again. This eliminates a special adaptation of the light image to different colored individual lights.
  • the individual lights can be designed as light emitting diodes (LED).
  • LED light emitting diodes
  • Light-emitting diodes have the advantage that, with their small size, low weight and low power consumption, they also enable a very high luminous efficacy and are particularly durable. This is the maintenance As well as the operating costs reduced and the stability of the image carrier with the light elements is improved by the low weight.
  • control device may additionally comprise a light sensor for measuring the ambient brightness. This makes it possible to automatically turn on or off the light image depending on a reading of the light sensor. Accordingly, the image of the image carrier in daylight is not affected, while the operation on the display of the light image can be started as soon as viewing the image on the image carrier due to darkness is no longer effectively possible.
  • the image carrier 1 is here in the form of a giant poster executed, which is clamped to a framework 2 and fixed.
  • the giant poster 1 is made of a flexible mesh vinyl and printed on its entire front with a picture.
  • the giant poster 1 on a plurality of circular recesses 3, which are arranged in a matrix-like manner in the horizontal and vertical directions at a distance of about 15 cm side by side.
  • the edges of the recesses 3 are reinforced - for example, with a ring eyelet made of plastic.
  • the framework 2 is a rectangular tubular steel frame, which is placed on the ground.
  • the scaffold 2 is attached at a plurality of points to a building, not shown, which is located on the back of the frame 2.
  • a clamping mechanism not shown, is provided, over which the edges of the giant poster 1 are firmly clamped.
  • the lighting elements 4 are provided with corresponding clip devices which reach over the reinforced edges of the respective recesses 3 and hold the lighting elements 4 there.
  • terminals, via which the light-emitting elements 4 are clamped at the edge of the recesses 3, or Velcro closures can be provided.
  • Connecting cables 5 extend in the horizontal direction between the lighting elements 4.
  • the lighting elements 4 are connected to the connection cables 5, wherein the position corresponds to the recesses 3 through the distances on the connection cable 5.
  • the connecting cables 5 are connected to a control device 6. This is contrary to the basic representation of FIG. 2 Usually held on the frame 2 at the back of the giant poster 1, so that the control device 6 from the front of the giant poster 1 is not visible.
  • the light-emitting elements 4 each have three individual light-emitting diodes in the RGB colors, which can be controlled individually via the control device 6. Each luminous element 4 thus forms a colored luminous spot.
  • a light sensor 7 is mounted, which is also connected via a connecting cable 8 to the control device 6.
  • the light sensor 7 can be embodied in a manner known per se, for example as a light-sensitive photodiode, which supplies a measured value for the brightness.
  • the control device 6 Depending on the measured value of the light sensor 7, the control device 6 generates a luminous image on the giant poster 1 in the evening and at night.
  • the light-emitting diodes of each luminous element 4 are individually driven so as to produce the desired color from the individual light-emitting diodes reassemble.
  • the totality of the light elements 4 thus forms a light image according to the principle of a point image.
  • the brightness of a luminous element 4 is controlled by the control device 6 by a uniform change in the brightness of the associated light-emitting diodes.
  • the image represented in this way can also be a moving image by rapidly changing the brightnesses of the RGB colors of the individual luminous elements 5.
  • the light image is completely independent of the imprinted on the giant poster 1 image.
