The front of the LED lamella comprising LED modules is covered by a transparent waterproof film; perforated covers are mounted on the film and are affixed to the surface of the LED modules by means of catches which grip the external current-conducting profile on two sides. For exchanging data with the LED modules, electromagnetic radiation is used which propagates along the waveguides arranged within the current-conducting profiles.

Description

Wireless LED lamella device

The invention relates to the field of devices for presenting changing information material and can be used to create devices for demonstrating outdoor video ads.

From the current level of technology, a device for an LED module for video screens is known (CN 202049690 U, G09F 9/33, 11/23/2011). The device contains a printed circuit board with LEDs soldered on the front side. The circuit board with LEDs is covered with waterproof sealant on both sides. An aluminum mask with holes is installed on the front. Rear mounted

waterproof plate. The whole structure is fastened with screws. The first disadvantage of this device is a complex device

sealing, which includes coating the modules with sealant and

waterproof plate through which signal connectors are output. Such a device complicates assembly and maintenance. The second disadvantage of this device is the large number of screws that are used in the design, which increases the complexity of providing

waterproofing. This solution is not optimal from the point of view of production. The third disadvantage of this device is the use of an aluminum mask, which protects the front side of the LED module. Making such a mask is complicated and expensive compared to making a mask from plastic. In addition, an aluminum mask will require additional surface painting in black. A fourth disadvantage of this device is an inefficient method of transferring heat from a printed circuit board with LEDs to the device body. When using a sealant layer, the heat transfer efficiency is quite low due to the small coefficient of thermal conductivity of the sealant. When using fins of an aluminum case for heat dissipation, the problem arises of providing reliable electrical insulation of the surface of the printed circuit board from aluminum fins (conductive tracks are usually located on the surface of the printed circuit board).

From the current level of technology, a LED screen device is known which includes long and narrow LED modules (CN 201465464 U, G09F 9/33, 05/12/2010). The LED modules of this screen consist of several LED strips, an aluminum profile and a light diffuser, which is mounted in front on an aluminum profile. The first disadvantage of this device is the inability to significantly increase the number of LEDs inside the LED module. With an increase in the density of LEDs on an LED strip and at the same time an increase in the length of the tape, the data flow required for broadcasting increases many times

high quality video images. Ensuring the transmission of the necessary data stream to a distance of more than one meter requires the placement of complex devices for receiving and processing data along the entire length of the LED strip, which is impractical from an economic and technological point of view. The second disadvantage of this device is the inability to increase the length of the LED module by more than 2 meters. This is due to the features of the LED strip device. The currents in the LED strip are transmitted through thin conductors that are applied to the surface of the strip. With an increase in the length of the strip, the current increases so much that the LED strip overheats and cannot function normally. Typically, such solutions are used in media facades, where 4-6 times lower brightness and low density of LEDs are required, respectively, and the currents inside the LED strip are much lower. The third disadvantage of this device is the large number of external electrical connections that must be provided when creating such LED screens . A large number of external connections creates 2 problems: increasing the cost of the LED screen due to the need to place a large number of waterproof connectors and cables; decrease in screen reliability due to the large number

connecting contacts and cables.

From the current level of technology, a LED module device is known in which an aluminum profile is used as a housing (US 7936561 B1, H05K 7/20, 05/05/2011). On the surface of the aluminum profile there are ribs that provide efficient dissipation of the heat generated by the LEDs. Current is supplied to the group of LED modules by means of insulated wires laid in the grooves of the aluminum profile. The contact of the boards with the wires is carried out by screwing self-tapping screws into the wires, which cut through the insulation and abut the wires. The self-tapping heads abut against the contact pads of the printed circuit boards of the LED modules located around the holes for the screws, this creates an electrical contact between the contact pads of the LED modules and the cores of the wires. Electric current is supplied to the wires and, passing through the self-tapping screws, feeds the LED modules. The first disadvantage of this device is there is a high probability of damage to the conductive core by one of the self-tapping screws, as a result of which the current will not be supplied to the subsequent modules. A second disadvantage of this device is the low reliability of the contact between the self-tapping screw and the cable core. It is difficult to ensure reliable contact of each self-tapping screw with a conductive residential wire in the device. The third disadvantage of this device is the lack of waterproofing of LED modules, which prevents the use of the device in outdoor conditions.

The prior art device for LED modules with surface-mounted LEDs, in which, as

waterproof layer used transparent film (CN 101021982 A, G9F 9/33, 12/20/2006). The device contains a printed circuit board with front-mounted LEDs for surface mounting, a protective film is placed on the surface of the board, and a perforated cover is placed above the film. The first disadvantage of this device is that water protection is provided for each LED module individually. To ensure water protection of the connecting wires and auxiliary electronic boards, additional devices must be provided. The second disadvantage of this device is poor water resistance at the edges of the printed circuit boards of LED modules. Printed circuit boards can accumulate moisture in small quantities, which can affect the life of LED modules. The third disadvantage of this device is the need to fasten the cover with bolts, which complicates the provision of waterproofing of LED modules.

Modern LED screens are sophisticated digital devices containing millions of elements. Due to the great complexity of LED screens, the architecture of engineering and electronic systems of LED screens is of particular importance to ensure reliability and quality. The creation of LED lamellas with wireless data transmission is aimed at solving the problem of creating a new type of LED video screens for the advertising industry, consisting of a set of long (up to 10 meters) LED lamellas, and increasing the reliability of such screens. LED lamella is a narrow and long strip, the front surface of which is covered with LEDs.

Lamella LED screens will have low weight, ease of assembly and maintenance, as well as architecture that allows you to set up fully automated production. Lamellar LED screens will be used for the deployment of large digital advertising networks that require standard-sized LED screens with high performance.

Until now, long and narrow LED modules have been used in media facades, where a separate LED module contained one line of LEDs and the length of the module was limited to 2 meters. Media facades have a number of design flaws: a large number of connectors leads to a decrease in reliability and an increase in the cost of the media facade; due to

design features of the media facade it is difficult to ensure a high density of LEDs per square meter and high image quality. So, in media facades, an increase in resolution leads to

increasing the number of individual LED modules and reducing

reliability of the entire screen. Due to the large distance between the LED modules, the media facades have low image contrast.

In the lamellar LED screen, unlike media facades, the length of the lamella is equal to the height of the screen and can reach 10 meters. In addition, the lamellas can contain dozens of LED lines, and the LED lines can be located at a distance of only 2 mm from each other, which will provide a high density of LEDs per square meter. The complexity of creating long LED slats for LED screens is due to several factors: the complexity of transmitting current into hundreds of amperes with low voltage over a distance of more than 1 meter; complexity of tightness

LED lamellas while maintaining the minimum distance between the individual LEDs and while maintaining the possibility of simple maintenance of the LED modules included in the LED lamella; the complexity of the transmission of the control signal in conditions of strong electromagnetic interference arising during the operation of LED modules; the complexity of ensuring high reliability, if necessary, to transmit data at high frequencies through a group of LED modules at a distance of up to 10 meters.

As you know, one of the main reasons for reducing the reliability of complex electronic systems is the low reliability of the connectors connecting various electronic components. The more pluggable contacts, the lower the reliability of the electronic system. Number of pluggable contacts in

Modern LED screens can reach several thousand per square meter. To ensure high reliability of data transmission in LED screens use high-quality and expensive connectors, this significantly increases the cost of the screen. There is also a problem of the reliability of the LED screen when connecting LED modules in series. If one of the LED modules fails, the entire chain of LED modules located behind it also stops working.

LED screens due to the large number of external cable connections require a lot of manual assembly operations, this makes it difficult to organize mass automated production.

The tasks to which this invention is directed are:

creation of LED slats up to 10 meters long with a high density of diodes per square meter of surface; the ability to create a new type

LED screen, consisting of long LED slats; creation of LED slats, which can be operated in conditions of high humidity, high wind loads and large temperature drops;

simplicity of assembly and maintenance of LED slats; providing effective passive cooling of the LED screen; reducing the number of contacts inside the LED screen to increase reliability; improving the reliability of data transmission to LED modules; reducing the influence of external electromagnetic interference on the transmitted signal; exclusion of the possibility of hacking wireless communication channels.

The tasks are solved as follows

The LED lamella with wireless data transmission consists of a group of LED modules (7). LED modules (7) are printed circuit boards (6) with front-mounted LEDs (8). On the back of the printed circuit boards (6) of the LED modules (7), there are power contacts (10) arranged in longitudinal lines. Behind the LED modules (7) are electromagnetic transceivers through which data is received and transmitted.

The housing of the LED lamella is an external conductive profile (1), in which one or more grooves (5) are located for

placement of internal conductive profiles (2). Internal (2) and external (1) conductive profiles serve as electric current conductors for power supply of LED modules (7). They are isolated from each other with using an insulating layer (3). As an insulating layer (3) between the conductive profiles (1, 2) can be used

electrical insulating film or electrical insulating coating, which is applied to the surface of the external (1) or internal (2) conductive profiles. The insulating layer (3) is made of a material with good thermal conductivity and serves to transfer heat from the LED module (7) to the external conductive profile (1). The external conductive profile (1) serves as a radiator for cooling the LED modules (7) and, for better cooling, may include longitudinal cooling fins located on the outside to improve heat transfer.

Internal conductive profiles (2) are placed in the grooves of the external conductive profile (1) and can have different designs: made in the form of a pipe of complex shape with holes (20) that serve to pass electromagnetic waves; made in the form of a pipe of complex shape with a longitudinal slit (21), which serves to pass electromagnetic waves; made in the form of a channel (22), repeating the shape of the groove of the external conductive profile (1); made in the form of an inverted channel (26) with flanges inclined at an angle inward, containing holes (20), which serve for the passage of electromagnetic waves.

LED modules (7) are placed on the surface of the external

conductive profile (1) in series so that the power contacts (10) of the LED modules (7) are in contact with the contact

surfaces (4) of internal (2) and external (1) conductive profiles.

LED modules (7) do not have a rigid connection to the external (1) and

internal (2) conductive profiles. With temperature differences

LED modules (7) can be moved inside the LED lamella, this solution reduces the load on the elements of LED modules (7), which can occur due to different coefficients of thermal expansion of materials from which the conductive profiles (1, 2) and printed circuit boards (6) of LED modules (7).

Front LED lamella with LED modules (7) is covered

translucent waterproof film (14) glued to the sides of the external conductive profile (1). Translucent waterproof film (14) can be made of easily stretchable material and has a continuous adhesive layer on its lower surface. When gluing b a translucent waterproof film (14) on the surface of the LED lamella, a translucent waterproof film (14) fits tightly on the surface of the LED modules (7) and adheres to it. Due to this, there is no air gap between the surface of the translucent waterproof film (14) and the surface of the LED module (7), which can interfere with the effective cooling of the LED modules (7). Perforated covers (11) are installed on the LED lamella above the translucent waterproof film (14), the openings of which are located opposite the LEDs (8) of the LED modules (7). Perforated covers (11) are fixed on the surface of the LED lamella using side latches (12), which cover the external conductive profile (1) on both sides.

External (1) and internal (2) conductive profiles have protrusions (15) on the front surface, designed to transmit electric current to LED modules (7). The contact surfaces (4) of the conductive profiles (1, 2) are plated with a low

resistance to electric current, not subject to the formation of an oxide film that impedes the passage of electric current. The power contacts (10) of the LED modules (7) can be conductive elements soldered to the printed circuit boards (6) of the LED modules (7), or they can be PCB tracks of the LED modules (7) that do not have an electrical insulation coating. Contact of the conductive profiles (1, 2) with an external current source can be ensured by the application of conductive busbars to the ends of the external (1) and internal (2) conductive profiles. Contact with an external current source can also be achieved by soldering wires to the external (1) and internal (2) conductive profiles.

To transmit data inside the waveguide (17) of the LED lamella, electromagnetic radiation with a wavelength of 100 nm to 300 mm can be used. To emit and receive electromagnetic electromagnetic waves with a wavelength of 100 nm to 1 mm, light emitters and photodetectors (LEDs (8) and photodiodes (19)) are used. Microwave antennas can be used for radiation and reception of electromagnetic waves of the lower part of the spectrum with a wavelength of 1 mm to 300 mm (18). Data through the waveguide (17) can be transmitted simultaneously from two sides, while a different frequency range of the spectrum of electromagnetic radiation can be used, which allows the transmission of the waveguide (17). Data can also be transmitted sequentially on one carrier frequency: first, one transceiver transmits data, and the other transceiver receives, then vice versa.

The data for controlling the LEDs (8) are transmitted to the LED modules (7) via modulated electromagnetic radiation, one or more longitudinal empty spaces located inside the conductive profiles are used as waveguides (17) along which the modulated electromagnetic radiation propagates (1, 2). The waveguides can be located inside the external (1) or internal (2) conductive profiles. Also, waveguides (17) are used to transmit data by modulated electromagnetic radiation in the opposite direction from LED modules (7) to the central video controller. The inner surface of the waveguides (17) is made of a material that well reflects electromagnetic radiation in the entire used frequency range.

The ends of the LED lamellas are closed by waterproof end caps (13). At the beginning of the LED lamella, a final cover (13) is installed, which includes one or more openings (23) that are transparent to electromagnetic waves in the used range, located opposite the ends of the waveguides. Through the openings (23) passes electromagnetic radiation in both directions. At the end of the LED lamella there is an electromagnetic radiation reflector (25), which prevents electromagnetic waves from being emitted into the outer space.

Device

placement of internal conductive profiles (2). Internal (2) and external (1) conductive profiles serve as electric current conductors for power supply of LED modules (7). They are isolated from each other using an electrical insulating layer (3). As an insulating layer (3) between the conductive profiles (1, 2) can be used

electrical insulating film or electrical insulating coating, which is applied to the surface of the external (1) or internal (2) conductive profiles. The insulating layer (3) is made of material with good thermal conductivity and serves to transfer heat from the LED module (7) to the external conductive profile (1). The external conductive profile (1) serves as a radiator for cooling the LED modules (7) and, for better cooling, may include longitudinal cooling fins located on the outside to improve heat transfer.

LED modules (7) are placed on the surface of the external

surfaces (4) of internal (2) and external (1) conductive profiles.

LED modules (7) do not have a rigid connection to the external (1) and

internal (2) conductive profiles. With temperature differences

Front LED lamella with LED modules (7) is covered

translucent waterproof film (14) glued to the sides of the external conductive profile (1). Translucent waterproof film (14) can be made of easily stretchable material and has a continuous adhesive layer on its lower surface. When gluing

a translucent waterproof film (14) on the surface of the LED lamella a translucent waterproof film (14) fits tightly on the surface of the LED modules (7) and sticks to it. Due to this, there is no air gap between the surface of the translucent waterproof film (14) and the surface of the LED module (7), which may interfere with the effective cooling of the LED modules (7). Perforated covers (I) are installed on the LED lamella above the translucent waterproof film (14), the openings of which are located opposite the LEDs (8) of the LED modules (7). Perforated covers (11) are fixed on the surface of the LED lamella using side latches (12), which cover the external conductive profile (1) on both sides.

To transmit data inside the waveguide (17) of the LED lamella, electromagnetic radiation with a wavelength of 100 nm to 300 mm can be used. To emit and receive electromagnetic electromagnetic waves with a wavelength of 100 nm to 1 mm, light emitters and photodetectors (LEDs (8) and photodiodes (19)) are used. Microwave antennas can be used for radiation and reception of electromagnetic waves of the lower part of the spectrum with a wavelength of 1 mm to 300 mm (18). Data through the waveguide (17) can be transmitted simultaneously from two sides, while a different frequency range of the spectrum of electromagnetic radiation can be used, which allows the transmission of the waveguide (17). Data can also be transmitted sequentially on one carrier frequency: first, one transceiver transmits data, and the other transceiver receives, then vice versa. The data for controlling the LEDs (8) are transmitted to the LED modules (7) via modulated electromagnetic radiation, one or more longitudinal empty spaces located inside the conductive profiles are used as waveguides (17) along which the modulated electromagnetic radiation propagates (1, 2). The waveguides can be located inside the external (1) or internal (2) conductive profiles. Also, waveguides (17) are used to transmit data by modulated electromagnetic radiation in the opposite direction from LED modules (7) to the central video controller. The inner surface of the waveguides (17) is made of a material that well reflects electromagnetic radiation in the entire used frequency range.

The device is manufactured as follows:

Conductive profiles (1, 2) are made of aluminum by extrusion. If necessary, holes are made in the waveguides using the milling or drilling method, which serve to transmit electromagnetic radiation. After the manufacture of conductive profiles (1, 2), a protective varnish is applied to the contact surfaces (4), and the conductive profiles themselves (1, 2) are coated with an oxide film by anodizing. After anodizing, the protective varnish is removed with a solvent. Then, the oxide film is removed from the contact surfaces (4) using an alkaline solution, and a metal coating is applied on the contact surfaces (4) by galvanic method, not

prone to oxide film formation.

After manufacturing, the conductive profiles (1, 2) are assembled in

conductive assembly. For this, an electrical insulating layer (3) is applied to the external conductive profile (1). The electrical insulating layer (3) may be made in the form of an electrical insulating film, which is glued to the surface of the external (1) or internal (2) conductive profile.

The insulating layer (3) can also be formed by applying a solution that, when solidified, will form a film on the surface of the external (1) or internal (2) conductive profile. After applying the insulating layer (3), the internal conductive profiles (2) are inserted into the grooves (5) of the external conductive profile (1) and fixed there with glue.

The electronics of the LED lamella are made as follows: first, printed circuit boards (6) are manufactured by the standard industrial method. Then, electronic components are installed onto the printed circuit board (6) by automatic surface mounting. At the next stage, the electronic components are soldered to the printed circuit boards (6) in the convection oven. LED modules (7), if necessary, can be coated with a water-repellent release coating by spraying a release solution on the surface of the LED modules (7). If electromagnetic

transceivers are made in the form of removable modules; they are connected to the boards of LED modules (7).

Next, LED modules (7) are installed on the conductive assembly so that the contact surfaces (4) of the conductive profiles (1, 2) are installed on the contacts (10) of the LED modules, and the electromagnetic transceivers of the LED modules are placed opposite the holes (20) in the conductive profiles, serving for the arrival of electromagnetic radiation into the waveguide (17) and vice versa.

Translucent waterproof film (14) is made by extrusion of polyurethane or another polymer. Translucent

waterproof film (14) can be made with or without an adhesive layer. Using a film applying device that contains a roll of a translucent waterproof film (14) and a device for pressing the film to the side surfaces of the external conductive profile (1), a translucent waterproof film (14) is glued to the side surfaces of the external conductive profile (1). The application of a translucent waterproof film (14) occurs by moving the film-coating device from one end of the LED lamella to the other, as a result, the translucent waterproof film (14) is unwound from the roll and applied to the surface of the LED lamella. In order for the translucent waterproof film (14) to fit tightly on the surfaces of the LED modules (7), after applying the film inside the LED lamella, a zone of discharged pressure is created for a short time. As a result

a translucent waterproof film (14) is firmly pressed to the surfaces of the LED modules (7) and glued to them.

At the final stage of assembly of the LED lamella, perforated covers (11) are installed on the front side, which are fixed on the sides of the external conductive profile (1) using latches (12), which are part of the perforated covers (11). After that, a layer of silicone sealant is applied around the ends of the LED lamella and the end caps (13) are installed. End caps (13), which are screwed to the external conductive profile (1) with screws or are fixed with glue. The end caps (13) can be made or have inserts made of a material transparent to electromagnetic radiation and light, for example, plastic. Covers (11, 13) can be made by injection molding of plastic.

The operation of the device is as follows:

LED modules (7) are placed sequentially on the surface of the external conductive profile (1), while the electromagnetic

transceivers are placed opposite the holes for walking

electromagnetic waves (20) or opposite the gap for passage

electromagnetic waves (21). Thus, electromagnetic radiation can come from the waveguide (17) to the electromagnetic transceivers and radiate back to the waveguide (17).

At the beginning of the LED lamella there is an end cap (13) with holes for inputting power buses (24) and an aperture for the passage of electromagnetic radiation (23). During the operation of the device, the power busbars are inserted into the holes for the input of the power busbars (24) and are in contact with the conductive profiles (1, 2), which makes it possible to supply current to the conductive profiles. Conducting profiles (1, 2) are isolated from each other using an insulating layer (3). Through the window for the passage of electromagnetic waves (23), electromagnetic radiation modulated by the control signal is supplied to the waveguide (17) of the LED lamella, and electromagnetic radiation modulated by signals from the electromagnetic transceivers of the LED modules (7) is returned from the waveguide (17) of the LED lamella. At the end of the line is the end cap (13) with a reflector of electromagnetic radiation (25). During the operation of the device, electromagnetic waves pass through the waveguide (17) and are reflected from the reflector of electromagnetic radiation (25). This solution avoids the emission of electromagnetic waves into the environment, and also reduces the loss of electromagnetic radiation, which ultimately reduces the transmitter power and the sensitivity of the receiver of electromagnetic radiation.

When installing LED modules (7) on the conductive profiles (1, 2) in the places where the contact surfaces (4) of the conductive profiles (1, 2) come in contact with the power supply (10) of the LED modules (7),

electrical contact. When power is applied to the conductive profiles (1, 2), it enters the LED modules (7) through the power contacts (10).

LED modules (7) contain LEDs (8), which are connected via LED drivers (9) to power contacts (10). LED drivers (9), receiving a control signal from video controllers built into LED modules (7), supply current pulses to LEDs (8). An electric current flows through the LEDs (8), as a result of which the LEDs (8) emit light. The light emitted by the LEDs (8) passes unhindered through

translucent waterproof film (14) and holes for LEDs (16) in perforated covers (11). The perforated covers (11) have a black light-absorbing surface, due to which the LED lamella has a high contrast.

LEDs (8) and LED drivers (9) during operation dissipate 90% of the incoming electricity as heat. LEDs (8) and LED drivers (9) heat the printed circuit board (6) of the LED module (7), which

installed directly on the insulating layer (3), which has high thermal conductivity. Thermal energy passing through

the electrical insulating layer (3) is transferred to the external conductive profile (1) and dissipated by heat exchange with air and in the form of infrared radiation. To improve heat transfer through infrared radiation, the back surface of the external conductive profile (1) may have a black coating.
