Description

LED modular device

DESCRIPTION

Object of the invention

The present invention relates to a modular device of LEDs especially suitable for application in transparent doors.

The modular device of LED's object of the present invention allows to maintain a high degree of transparency in the doors or windows where it is applied, while at the same time allowing to provide said doors or windows with improved features such as advertising support or information display of any kind.

The modular LED device object of the present invention is of special application in the field of LED display industry, as well as in the field of industry related to the design, marketing and installation of glazed doors and advertising stands or posters.

Technical problem to be solved and Background of the invention

At present, many types of advertising media or posters are known where information of any kind is shown, whether of a purely commercial nature, or of information in general.

At the entrance of a shopping center, hospital, public administration building, etc., you can also frequently find posters showing a directory with the different departments and their precise location in that building.

Likewise, in police stations, it is common to find screens showing notices about particularities that citizens must take into account when making certain procedures such as the renewal of their IDs, passports, etc., or with public security notices where, for example, photographs of people in search and capture situations are shown.

For reasons of lighting and / or aesthetics, many of these buildings have transparent glazed doors that let light through, for example, to take advantage of the light entering the building from a window located on the other side of the door. In these situations, it might be convenient for the public that is waiting in a waiting room (which is equipped with windows) to receive certain notices on posters located on a door, which is thus used as a message support, while that said door let in the light that enters through the windows of the waiting room, to the opposite side of the door, where for example a room without windows would be found.

Through the traditional posters on paper support, it is possible to display information towards a certain room (eg the mentioned waiting room). However, this type of posters blocks the passage of light to the opposite side of the door, so that said door, despite being made of transparent material, will no longer fulfill its function of allowing the passage of light through it. .

There are also message supports in the form of flat screens, attachable to doors. These screens are in many cases LED technology screens. However, due to the current technology, these screens comprise an opaque background and / or structural elements that prevent the passage of light through it, and that interrupt the continuity of the projected image.

Thus, the present invention aims to provide a modular LED device that meets a series of objectives, not achieved as a whole by means of existing technologies at present: take advantage of the glazed door as a message carrier; allow the passage of light through the door; achieve the projection of messages without elements that interrupt the image shown, and; provide a certain degree of privacy for the opposite side to the area towards which the messages are displayed.

The modular LED device object of the present invention is especially suitable for quick and easy installation in transparent doors. For this, the device has elements that allow its coupling to any door transparent already existing, thereby avoiding having to design a specific door that incorporates a screen and / or avoiding complex installation work of a screen on a door.

Detailed description

The present invention relates, as already mentioned above, to a modular LED device.

The device consists of one or more LED modules (1).

Figure 1 shows an exploded perspective of the constituent elements of an LED module (1).

For its part, Figure 2 shows a view of a finished LED module.

Each LED module (1) comprises a plurality of parallel LED strips (2), supported and separated from each other by bars (3). Said LED strips (2) preferably comprise a PCB board with a plurality of LED diodes (4) aligned.

The bars (3) that support and separate the LED strips (2) are preferably made of transparent material, and more preferably in methacrylate.

Each of the LED strips (2) is connected, at one end, to a motherboard (5) comprising a controller card (7).

Each LED module (1) has a side block (6) that includes the mentioned motherboard (5), the controller card (7) and the module or power supply (60). Preferably, the side block (6) is closed by a housing (8).

Figure 7 shows a schematic view of the motherboard (5), without the controller card (7).

The side block (6) is therefore configured to receive the mechanical and electrical connection of each of the LED strips (2).

The side block (6) is also configured to couple two plates (9) of transparent material, on both sides of the set of LED strips (2), so that said plates (9) produce a compact closure of each LED module (1 ).

The plates (9) of transparent material are preferably made of methacrylate.

The device preferably incorporates slats (10) and fixing means (10b) (set of screws and nuts or similar elements). Each ribbon incorporates first threaded fasteners (10a) for fixing, by means of fixing means (10b), of the two plates (9) of transparent material hugging the set of LED strips (2) and, therefore, for compaction of the LED module (1).

Said slats (10) are preferably made of metallic material, and are arranged on the back side (1b) of the LED module (1) opposite the front side (1a) by which the information of the LEDs (4) is shown for , in this way, do not interrupt the image to be reproduced by the LEDs (4).

The modular LED device also comprises anchoring elements (11) to a door (12) or window.

Said anchoring elements (11) comprise at least a second threaded fastener (11a), for coupling with the LED module (1). Moreover, said anchoring elements (11) are configured to be anchored to the door (12) or window, preferably by means of an adhesive (preferably a transparent adhesive). To this end, preferably, said anchoring elements (11) have an adhesive face (11b).

The anchoring elements (11) can be made of metallic material, or transparent material, such as methacrylate.

For the compact closure of the modular LED device, the device incorporates covers (13). Preferably, a first cover (13a) includes holes (14) for the passage of the power and data transmission cables of the device. Preferably, a second cover (13b) does not include the mentioned holes (14).

In the event that the device includes a single LED module (1), the LED module (1) closes on a first edge (1c) with the first cover (13a) and on a second edge (1d), opposite the first edge (1c), closes with the second cover (13b).

The covers (13) are configured for coupling with the slats (10) for fixing the device and with the upper and / or lower base of the door (12) or window, by means of first fixing plates (15). Figure 5 shows a possible embodiment of one of said first fixing plates (15).

In the event that the device includes a plurality of LED modules (1), only each of the LED modules (1e) located at the ends of the device (LED modules (1e) that only connect to another LED module (1) by only one of its edges (1c, 1d)) incorporates one of the mentioned covers (13) in the edge (1c, 1d) that is not connected with an adjacent LED module (1).

In case the device includes a plurality of LED modules (1), each LED module (1) is coupled to one or two adjacent LED modules (1) by means of second coupling plates (16).

Figure 3 shows the way in which the different LED modules (1) of the modular device are assembled in a door (12), so that they cover the total surface of the door (12).

Figure 4 shows a schematic view of a possible embodiment of one of the anchoring elements (11) of the LED modules (1) to the door (12) or window.

Figure 6 shows a schematic view of a possible embodiment of one of the second plates (16), for mutual coupling between adjacent LED modules (1).

As already introduced, the LED modules (1) of the device are configured with fixing means (10b) (screws and nuts, bolts, threaded males, or the like) configured to attach the plates (9) to the first threaded fastener ( 10a) of the fixing slats (10).

Likewise, the LED modules (1) are configured with threaded elements (11c) for coupling with the anchoring elements (11).

The fixing slats (10) can adopt various geometries. In the figures of this document they have been represented as elongated strips to which the LED modules (1) are fixed by means of said fixing means (10b).

ll

The anchoring elements (11) can also adopt various geometries. The anchoring elements may be arranged in correspondence with the four corners of the door (12) or window.

It is not necessary that each of the LED modules (1) of the modular device be coupled to an anchoring element (11). Provided that the coupling between the different LED modules (1) that make up the device is carried out in a firm and reliable way (which is achieved by means of the aforementioned second plates (16)), it is sufficient that only the LED modules (1e) located at each end of the modular device incorporate or attach the aforementioned anchoring elements (11) to the door (12) or window.

According to a preferred embodiment, the LEDs (4) of each of the strips (2) of each LED module (1) are connected in series, so that the controller card (7) has implemented a transmission protocol of serial data to the LEDs (4) of each strip (2).

Given that each strip (2) comprises a large number of LED diodes (4) connected in series, the serial data transmission protocol is characterized by introducing a reduced latency in the data transmission to the LED diodes (4) , so that no delay can be seen in the information shown by the LEDs (4) of each strip (2).

According to a possible embodiment, the integrated circuits (17) of each of the LED strips (2) are located in correspondence with, and behind certain LED diodes (4), so that said integrated circuits (17) do not are visible from the front side (1a) of the LED module (1).

According to a possible embodiment of the device, due to the length of each LED module (1), each strip (2) is made in at least two sections joined together by welding. Said welding is preferably carried out at low temperature and with a high tin content in the weld bead, to strengthen the joint between the sections and make said union more reliable and durable.

Figure 8a and Figure 8b show respective sections of an embodiment of the LED diode strip (2) (4).

Preferably, a control system (not shown) is associated with the modular LED device. Said control system comprises temperature, humidity, smoke, vibration sensors, voltage and current meters, etc. Said sensors are connected (by cable or wirelessly) to a data processing center, which in turn communicates the data (by cable or wirelessly) to a server.

By means of a remote terminal (not shown) with wireless connection to said server (via Bluetooth®, WiFi, 3G connection, 4G, 5G, GPRS, GSM, etc.), and by means of a program or application installed in said remote terminal, you can control from said remote terminal the status of all the components of the modular LED device, and alarms can be received in case any of said components (diodes (4), power supply (60), etc.) is not functioning properly.

From the remote terminal, and by means of the sensors and the program or application, it can be observed what content or image is being reproduced at any time by the LED modules (1), being able to alter or modify said content to be reproduced by means of a corresponding instruction sent From the remote terminal.

Thanks to the transparency of the plates (9), the modular LED device object of the present invention is much less susceptible to heating than other conventional LED screens.

Also, thanks to the transparency of the plates (9) and that the controller card (7) and the power supply (60) are confined in the side block (6), said elements do not occupy a dispersed space on the surface of the module LED (1). This feature differentiates the modular LED device from other conventional screens, where the controller cards and / or the power supply (60) are positioned dispersed along the screen surface. This makes the background of these screens mostly opaque, which prevents the passage of light through the screen.

The fact that the LED modules (1) of the modular LED device object of the present invention are much less susceptible to heating than other conventional screens makes it possible to dispense, in the case of the present device Modular LED, of a cooling system, a system that is present (in the form of fans) in many conventional LED screens.

By using a modular LED device such as that described, degrees of transparency of 75% can be typically achieved, so that on the front side (1a) of an LED module (1) the image reproduced by the LED diodes (4), unable to see through the door (12), while at the rear (1b) of the LED module (1) (opposite side of the door (12)) can be received, with virtually no loss , the light coming from the other side of the door (12).
