Definitions

• the present invention relates to a light box with at least three basic profiles, which form a closed base frame in the mounted state, to which a first tensionable sheet material to be illuminated can be used so that it forms the front side of the base frame.
• the light box has at least one light-emitting means, which is arranged within the base frame to illuminate the light box, and at least one power supply, in particular an electronic ballast, to supply the light source with electricity, and at least one arranged on the back of the base frame support wall, the Has at least one fastening means for releasably fixing the lamp and / or the electronic ballast within the base frame.
• Light boxes of the type mentioned are well known and are described for example in the G 9002394 Ul.
• This document discloses a lightbox for use in illuminated advertising comprising a base frame having at least one interchangeable rigid advertising disc.
• the base frame is formed from profiled strips, the positive and / or non-locking interlocking locking means for attachment to each other.
• the change of the advertising motif is done by changing the advertising disc, which is inserted between a likewise rigid frame and the base profile.
• the frame is first released by applying forces from the base frame, then removed the old rigid media disc and replaced by a new also rigid advertising disc and finally the frame fixed by the latch again on the base frame.
• a disadvantage of this system is, on the one hand, that the geometric dimensions are already established during the production of the base frame and can not be changed at a later time.
• these light boxes are shipped almost exclusively in the assembled state, which makes handling difficult and with high packaging and shipping costs. Even a shipment in the disassembled state, the handling can not be significantly easier, especially since only the weight to be supported can be reduced, but not the resulting through the rigid back wall or through the advertising disk bulkiness due to the dimensions of the latter.
• the transport to possibly changing locations is very expensive with dimensions of for example 5m x 3m. If, for example, the light box is used as illuminated advertising medium in large department stores and is to be used in different departments on different floors of the department store due to seasonal use, it may be necessary to transport the light box via a staircase or an escalator or an elevator.
• the rigid format of the previously known light boxes is very disadvantageous and thus limits the dimensions of the light box on the local conditions such as clearance in the escalators.
• the Applicant has been offering for some time unlit, modular variable advertising media consisting of four basic profiles that are composable to form a closed base frame in the assembled state, in the the advertising medium is used.
• Basic profiles and advertising media can be shipped or transported disassembled so that a rebuild is very easy even within different floors of a department store.
• the basic frame can also be easily adapted to a possibly changed format of the advertising medium.
• billboards with formats up to 3m x 10m can be realized.
• the support wall is formed by a second tensionable sheet material, which is fastened to the base frame so that it forms the back of the light box.

• the tensionable sheet material may be designed as one or more parts and, for example, be composed of two or more individual tensionable surface materials.
• the format of the light box is changed, then simply another adapted to the new dimensions tensionable sheet material can be used in the modified base frame.
• the erector of such a light box simply order the corresponding flexible back wall at the manufacturer if necessary, together with the new motif to be illuminated and sent by standard package or parcel through the post. It is no longer necessary to build a completely new lightbox for another format. Instead, the change in format is achieved by exchanging two profiles and the two stretchable sheet materials. This achieves an almost limitless scalability of the light boxes adapted to the motifs to be illuminated. This results in a significant cost savings.
• both the height and the length of the base frame can be adapted to the format of the advertising medium to be used without much design effort.
• the lamps perpendicular to the mounting rail.

• the lighting means can be fixed in position by means of a safety device, in particular a securing loop, against unintentional release from the fastening rail. This prevents that the stretchable surface material is damaged by a possible loosening of a bulb.
• the bulbs are connected in series via a pre-assembled plug-in system.
• up to forty bulbs can be connected in series (this corresponds to about 1000 W depending on the type of light), which allows a scaling of the base frame up to a size of 3m x 10 m, without the need for another power supply in the light box must become.
• the wiring can be done by prefabricated cables with different lengths, where light plugs are attached, so that a connection from bulb to bulb by simply plugging the lamp plug takes place, If the number of bulbs are increased, it is only necessary a corresponding cable in the connect the last lamps in the series connection and connect them to other lamps. In this way, up to forty bulbs can be connected in series to a power connection. Due to the different lengths of the cable, it is also possible to fix the lamps according to the desired use and the intensity of the illumination with different distances from each other on the mounting rail.
• the light sources in the light box are surrounded by a sheath, so that, in the event of a breakage of the light source, the components that are at risk of injury, such as, for example, broken glass, remain in the sheath.
• the lighting means may be provided with a UV filter. This can already be integrated in the casing.

• the cross member may also be permanently attached to the base frame and be pivotable, for example via a joint in a position in which a simple mounting of the support wall to the cross member is possible.
• the tension of the support wall is caused in this case by a kind of self-tension either by its own weight and can also be supported and reinforced by attachable in the opposite edge or edge region of the support wall additional weights.
