Definitions

  • the invention relates to a light advertising and information device, consisting of a housing with a frame, a glass plate framed by this frame with an information carrier as the front wall and a rear wall and a light source arranged in the housing.
  • the Swiss patent specification No. 258 457 shows a light advertising apparatus, the front wall of which consists of a transparent mirror.
  • the advertisement, or the information carrier is located on the rear wall of the device or is applied directly to the inner surface of the mirror.
  • Lighting elements are arranged between the rear wall and the mirror, by means of which the advertising image can be illuminated and thus made visible.
  • the light sources are switched off, the mirror is opaque from the outside and no advertising is visible.
  • the advertising image is illuminated very unevenly, which is disturbing for the viewer.
  • the light sources arranged in the area of the mirror surface also have a disruptive effect and reflections make the advertising image sometimes difficult to read.
  • the device described can only be used on one side. If an advertisement image is to be visible on the front and on the back of the device, the device must be equipped with a central partition and a double supply of light sources.
  • the inside of the glass plate is provided with a light at least partially reflective coating
  • the information carrier is arranged between the outside of the glass plate and a second glass plate
  • the rear wall which is arranged at a distance from the glass plate is provided with a light reflecting coating on the inside
  • the light source is arranged outside the visible part of the glass plate in the region of the frame.
  • the light source is not directly visible from the outside, and the emitted light only partially passes directly through the coated glass plate.
  • the portion of light that is not let through by the coated glass plate is reflected on the inside of the plate, hits the coated rear wall and is reflected there again to the front wall or the glass plate. Here a part of the light emerges again and a remainder is reflected again.
  • the image can consist of a slide, a transparent film or another image carrier.
  • light sources are arranged both below and above in the frame, and also in the side parts of the frame.
  • the device can be made very thin in this way and in extreme cases is only a little thicker than the diameter of the fluorescent tube and the mass of its installation base.
  • the rear wall also consists of at least one glass plate with a light-partially reflecting coating on the inside and has an information carrier.
  • This version allows the use of the front and back of the device. When the light source is switched on, part of the emitted light emerges from both the front and the back, and the other part is reflected to the opposite coated glass plate, or front or rear wall. Both the front and rear wall, or the advertising or information images arranged on them, are illuminated evenly.
  • the partially reflective coating advantageously consists of a plastic film with metal vapor deposition.
  • plastic films with metal vapor deposition are available in various embodiments on the market and are used, for example, for coating glazing in buildings or for thermal insulation.
  • the partial permeability of these foils is used, coatings of different thicknesses being selected depending on the desired permeability.
  • the light source advantageously consists of a fluorescent tube.
  • Fluorescent tubes enable the light source to be optimally adapted to the dimensions of the device and also generate little waste heat.
  • the device consists of a rectangular frame 1.
  • This frame 1 comprises a front wall 2 and a rear wall 3.
  • the front wall 2 consists of a glass plate 4, which is provided with a coating 5 on the inside and a second glass plate 7. Between the two glass plates 4 and 7, a slide film is inserted as an information carrier 6, on which an advertising image is recorded.
  • the coating 5 consists of a highly transparent polyester film, which is provided with an optically clear aluminum vapor deposition. The vaporized film is glued to the glass plate 4. This commercially available coating partially reflects incident light, ie it is partially transparent.
  • the coating used is of the 3M / P18 type.
  • the rear wall 3 consists of a plate impermeable to light, for example metal, which has a light-reflecting coating 8 on the inside.
  • a light source 9 in the form of a fluorescent tube is arranged in the lower part of the frame 1. This fluorescent tube is connected to power supply and switching devices, not shown.
  • Light rays 10 and 11 emanating from the fluorescent tube 9 strike the coatings 5 and 8 and are at least partially reflected by them.
  • the light beam 10, for example first strikes the coating 5, which is partially transparent. Therefore, only a part of the incident light quantity is reflected and another part emerges as a light beam 12 through the glass plates 4 and 7 and the information carrier 6.
  • a second light beam 11 first strikes the coating 8 of the rear wall 3 and is completely reflected there, whereupon it strikes the coating 5 of the glass plate 4. Since this is partially transparent, only a part of the light is reflected here, and the other part also emerges from the device as a light beam 13.
  • the interior 14 of the device is completely penetrated by light and the information carrier 6 is uniformly illuminated in the visible area of the glass plate 4.
  • the upper part 15 of the frame 1 is provided on the inside with a reflective coating 16, which reflects incident light rays back into the interior 14 of the device.
