Abstract

FIELD: advertisement.

SUBSTANCE: invention relates to advertising and can be used for creation of street advertising video displays. Light-emitting diode display is made of two modules of the flat material, on one of which there are light-emitting diodes with individual control chip. In so doing the light-emitting diodes are connected in series with each other. Module with LEDs fixed on it is closed by the second module, which is a protective screen of the same size as the previous module, and is made from optically transparent or light-transmitting material. Modules are connected along the perimeter, through the spacer, creating a tight space between the modules.

Description

The invention relates to the field of street advertising and can be used to create street advertising video screens. It can also be used as an interior information board, screen, light illumination, to be both outdoor and outdoor.

Street LED screens are known from the prior art that are assembled from separate modules, each module being sealed and is a finished product. Examples of such systems are described in patents US 8384616 B2, 02/26/2013 and US 8172097 B2, 05/08/2012. In these patents, the module is a metal case with LEDs located in front, and ventilation holes and a cover for accessing the electronics are located at the back. The module contains a controller inside it that controls the drivers of diodes, boards with soldered diodes, power supplies. Such modules are usually serviced exclusively at the rear, in rare cases, such structures provide front-side maintenance, and there are almost no engineering solutions for servicing the modules at the rear and front. To access the electronics of the module, you must remove the entire module. The inability to maintain the electronics of the screen at the back and front limits the scope of such LED screens. The use of massive metal screen cases also limits the scope of the screens, which does not allow the installation of such screens directly on the walls of buildings.

A LED screen CN 101710472 (A) is known from the prior art on 05/19/2010, the facade of which is made of glass, in which through holes and recesses are made in the form of grooves, for installing lenses in these holes directing light from LEDs mounted in the desired direction on a tape inserted into the groove in the glass, from the inside.

The disadvantages of this screen are the high mass, the complexity of the mount, the lack of complete tightness.

The technical result of the present invention is to reduce the weight of the LED screen by facilitating the design by using lightweight materials for the facade of the screen, ensuring complete sealing of the screen and increasing the convenience of mounting the screen.

The specified technical result is realized due to the fact that the LED screen is made of two modules of flat material, on one of which LEDs with an individual control chip are fixed, in any design and quantity (cluster, LED strip, module, panel). In this case, the LEDs are connected in series with each other. The module with the LEDs mounted on it is closed by a second module, which is a protective screen, the same size as the previous module, and is made of optically transparent or light-transmitting material. These two modules are connected around the perimeter, through a spacer of the required size, creating a tight space between the modules by means of a sealant. At the same time, an aluminum spacer used in the manufacture of double-glazed windows can be used as a spacer. In a broad concept, the spacer can be made of any suitable material, the necessary hardness. The supply of signal and power wires to the LEDs is made through a hole in the spacer or in the material on which the LEDs are fixed, these holes after wiring the wires must be sealed to achieve tightness inside the planes. The LEDs are controlled through signal and power wires, using the LED controller, forming an image with it. In that case, if you use glass as the facade modules of the screen, then the specified screen will be presented in the form of a “window double-glazed window”, with LEDs glued and fixed inside the double-glazed window. Thus, the installation of this screen will consist in replacing the glass in the existing window frame. It does not require a special mounting system, does not require a special frame in the screen. It has a significantly lower weight in comparison with the matrix screen, which reduces installation time, and does not change the appearance of the building.

Moreover, in screen options that are not a “glass window” (when using organic glass, monolithic polycarbonate or other suitable materials as facade modules), the screen can be installed in any optimal way. For example, through openings in the screen that do not violate the tightness of the screen, provided for in a particular case in the design of the screen, for its installation.

In a particular case, the mounting holes in the screen are made on the rear and front modules of the screen located on the same axis passing through the center of the holes. On the same axis, between the rear and front screen modules, a distance ring is installed, the inner diameter of which is equal to the diameter of the holes in the rear and front screen modules, on the axis of which it is installed. In this case, the outer diameter is determined by the wall thickness of the ring, which ensures the tightness of the screen, and may be equal to the thickness of the spacers around the perimeter of the screen. The height of the distance ring should be equal to the depth of the spacer. In this case, the spacer ring can be made of the same material as the spacer. On two planes of the distance ring adjacent to the rear and front screen modules, a sealant is applied to ensure the tightness of the screen.

Mounting holes can be made in any required quantity and place in the plane of the screen, but not limit the location of the LEDs in the screen. For example, between LED strips, or at the corners of the screen (in places free of LEDs mounted on the rear screen module). The diameter of the mounting hole should allow passage through it of hardware used to secure the screen.
