  • There are different types of lighting for light boxes including one-sided backlighting, two-sided backlighting or side lighting (e.g. from left and / or right and / or below and / or above) by coupling light into the air space of the light boxes from the side.
  • the lateral illumination can in particular comprise one-sided to four-sided illumination.
  • these lamps are stretched through the associated light box and can typically illuminate glasses, acrylic glasses and stretching cloths, which are combined on the front with a specially printed advertising film.

  • light can also be coupled into a light box from the side.
  • the light sources (partly with a reflector system) are attached to the side in the frames of the light box. These light sources couple the light from outside into the air space in the direction of the center of the box.

  • LED modules are also known as light sources, the LED modules being individually fastened, e.g. screwed, to the frames or to a rear wall of the light box.

  • the light modules no longer need to be screwed, riveted or glued directly to the body to be illuminated, but the light modules can simply be inserted into the profile rail by which they are held. In this way, assembly of the light modules can be considerably simplified, in particular if several light modules are to be used in a common profile rail.
  • the result is a particularly flexible and possibly also easily changeable positioning of the light modules, e.g. by moving or repositioning them in the same profile rail or in a different profile rail.
  • a luminance and / or a luminous distribution within the body to be illuminated, in particular a light box can be easily set. It has been shown that such a sheet metal thickness represents a particularly good compromise between sufficient elastic flexibility and sufficient mechanical stability.

  • the profile rail can not only be used for fastening light modules, but also for mounting other profile rails.
  • the profile rails can thus assume a double function as a holder for the light modules and as a mounting rail or mounting support for other profile rails. This simplifies storage and assembly and enables cheaper production.
  • the use of pairs of screw holes reduces the risk of waste when separating or assembling in the area of the screw holes.
  • profile rails also as mounting rails enables one-sided and two-sided alignment of the profile rails fitted with the light modules (and thus also the light modules), in particular for one-sided or two-sided backlighting of a light box.
