[technical field]
The utility model relates to a kind of LED screen, particularly a kind of ultra-thin screen of LED that can filter electromagnetic interference (EMI).
[background technology]
Along with industrial expansion, the generally use of LED product.The world in the communication prosperity, more and more countries will be paid attention to the electronic product, the particularly display screen of LED industry that electromagenetic wave radiation disturbs this part, be installed in for a long time indoor outside, will produce a large amount of electromagnetic waves during work, can play interference effect some radiobeams.Do not pass through if do not improve, will can't sell in some countries.At present, the screen body of other company's designs is when using, and radiation has the phenomenon of exceeding standard, and the magnetic radiation even the time spent generates electricity easily causes interference to other electronics; Serious if exceed standard with respect to domestic, national security agency's rectification of can giving notice is if not rectification or rectify and improve and do not pass through will be confiscated product or punished; And it is with respect to European countries, if radiation exceeds standard, product is to sell at market plane.Therefore, how designing a kind of electromagenetic wave radiation that can filter out disturbs the LED screen of (EMC) most important.
[utility model content]
Have the electromagenetic wave radiation serious interference in use in order to overcome existing LED screen, influenced the technical matters of the operate as normal of outdoor wireless electricity electric wave, the utility model provides a kind of ultra-thin screen of LED that can filter electromagnetic interference (EMI).
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of ultra-thin screen of LED that can filter electromagnetic interference (EMI) is provided, comprise the ultra-thin screen casing that is provided with groove, described ultra-thin screen casing one end is installed power supply input aviation seat, signal input aviation seat, power-supply filter, signal receiving card and Switching Power Supply are installed in the described groove, and described power supply input aviation seat, power-supply filter, Switching Power Supply, signal receiving card and signal input aviation seat connect successively; A shielding bonnet is also installed in the described groove outside.
Further, ultra-thin screen casing one end of described power supply input aviation seat and signal input aviation seat is a curved surface that caves inward.
Further, described Switching Power Supply is installed on a side in the groove, and described power-supply filter and signal receiving card are installed on the groove opposite side, and power-supply filter is positioned at the end near described power supply input aviation seat.
Further, also be provided with some thermal windows on the described shielding bonnet.
Further, described shielding bonnet is installed on the groove outside by web member.
Further, described web member is a plurality of screws.
With respect to LED screen of the prior art, the beneficial effects of the utility model are: the ultra-thin screen of this LED can effectively be controlled at electromagenetic wave radiation below the 30db, and it not only meets national standard, more meets European Union member countries' standard.

[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
The fundamental purpose of the utility model design is: the ultra-thin screen of the LED that can filter electromagnetic interference (EMI) that provides in use reduces it or even masks electromagenetic wave radiation fully and disturbs.
Consult shown in Fig. 1-2, the utility model provides a kind of ultra-thin screen of LED that can filter electromagnetic interference (EMI), comprise the ultra-thin screen casing 3 that is provided with groove 9, described ultra-thin screen casing 3 one ends are installed power supply input aviation seat 1, signal input aviation seat 2, in the described groove 9 power-supply filter 4, signal receiving card 5 and Switching Power Supply 6 are installed, described power supply input aviation seat 1, power-supply filter 4, Switching Power Supply 6, signal receiving card 5 and signal input aviation seat 2 connect successively; A shielding bonnet 7 is also installed in described groove 9 outsides.
Further, in the utility model: ultra-thin screen casing 3 one ends of described power supply input aviation seat 1 and signal input aviation seat 2 are a curved surface that caves inward; Described Switching Power Supply 6 is installed on a side in the groove 9, and described power-supply filter 4 and signal receiving card 5 are installed on groove 9 opposite sides, and power-supply filter 4 is positioned at the end near described power supply input aviation seat 1; Also be provided with some thermal windows on the described shielding bonnet 7, be used for the heat radiation of power-supply filter 4, signal receiving card 5 and Switching Power Supply 6 in the groove 9.Described shielding bonnet 7 is installed on groove 9 outsides by web member 8; Web member 8 is a plurality of screws, is preferably the M3 sunk screw, promptly shields bonnet 7 and covers groove 9 by a plurality of M3 sunk screws.
The concrete process of installing of the utility model is as follows:
Power lead was received power-supply filter 4 input ends above branch was imported aviation seat 1 with power supply earlier, the out-put supply that filters was connected on ultra-thin Switching Power Supply 6 input ends again; Simultaneously the transformation output terminal 5V of ultra-thin Switching Power Supply 6 is supplied with LED screen illuminating module and signal receiving card 5; Behind connection signal input aviation seat 2, signal receiving card 5 will be the conversion of signals of receiving computer on LED screen illuminating module; And under this duty, a plurality of electronic devices and components work, though most electromagnetic radiation is reduced, but can have little part; And then after will shielding bonnet 7 usefulness M3 sunk screws and being locked, the radiation of so little part will obtain bigger improvement.Consult shown in Figure 3, for adopting the testing radiation report waveform trend graph after the structure of the present utility model.
The utility model can effectively be controlled at electromagenetic wave radiation below the 30db after adopting above-mentioned structure, and it not only meets national standard, more meets European Union member countries' standard.Thereby bring more economic benefit to enterprise.
