Ledman shares recently awarded six patents

By people's Republic of China national intellectual property Council research, according to people's Republic of China patent law, recently, Ledman shares get six patent certificates which are LED displayed system, device and the method of reducing LED displayed system electromagnetic interference of invention patent, a protection institution& display, a waterproof institutions & display, and a luminous packaging unit & display and for COB package of printed circuit board structure &LED display for practical new patent, LED displays (1) for a design patent.

?Invention patent LED displayed system, device and the reduced LED displayed system electromagnetic interference of method public: LED displayed system including at least a displayed unit, the said displayed unit including connection of received card, and interface turned received Board HUB and at least a module, The receiving card is used to receive the common mode signal, And sends a common mode signal to the HUB ;The HUB comprises a common mode differential conversion circuit, and the two ends of the common mode differential conversion circuit are connected with the output end of the receiving card and the input end of the module respectively for transmitting the common mode signal received by the HUB And the HUB is also used to transmit the differential signal to the module; the module comprises a differential common mode conversion circuit, one end of the differential common mode conversion circuit is connected with the HUB and the other end outputs a common mode signal. In the above-described manner, the present invention can effectively reduce the electromagnetic interference of the LED display screen without affecting the increase of the frequency and without the need for the jacket magnetic ring.

The utility model patent "a protective mechanism and a display" discloses that the protection mechanism includes a main body and a fixing part, and the main body can be fixed to the object to be protected by the fixing part; the main body has at least two states in use, and in one of the states The free body of the lower body is away from the object to be protected and is in a first relative position relative to the object to be protected; in another state the subject is subjected to external forces such that its free end is at a second relative position relative to the object to be protected The first relative position of the elastic. In the above-mentioned manner, the utility model can effectively protect the corner and the edge of the protected object from collision.

The waterproofing mechanism includes a box body and a lid, the case is fixed to the case, the lid is fixed to the case, the lid side is pivotally connected to the box body side, and the other side is snap-engaged with the other side of the case, thereby covering or opening the case. In the above-described manner, the utility model can simplify the waterproofing mechanism and facilitate the maintenance.

The light-emitting package unit includes a package substrate and at least two light-emitting elements having different color temperatures. The package substrate includes a first surface and the second surfaces, at least two sets of light-emitting devices the light emitting elements are fixed on the first surface of the package substrate and are packaged together, wherein at least two of said light emitting elements are respectively in at least two circuits independently of each other. According to the above-mentioned aspect, the utility model can realize the adjustable color temperature of the single light emitting packaging unit, and is advantageous for improving the light quality of the light emitting packaging unit.

The utility model patent "Printed circuit board structure and LED display for COB package" discloses that a printed circuit board structure for a COB package includes a printed circuit board, an insulated injection molded layer fixed to the printed circuit board, Where in the injection molding layer is formed by injection molding, and the injection molding layer is provided with a plurality of grooves arranged in an array in which an encapsulation area for accommodating an LED chip is formed on the printed circuit board. The above-mentioned printed circuit board structure for COB package is formed by the injection molding layer and is fixed to the substrate by injection molding. The injection molding layer is produced at a high speed and high efficiency, and the operation can be automated to form a printed circuit board COB package is easier to achieve, the injection of the formation of the groove size of high precision, packaging, solid crystal position accurate, will not be offset, greatly improved yield, very suitable for small point spacing indoor LED display.

?Design patents of the LED display (1) public: iposter series appearance structure design.

?The six patents, is the State intellectual property Office of Lehman shares in the LED industry recognized by independent research and development ability, we believe that Ledman shares can be achieved more impressive achievement on patents.
