Abstract
The invention discloses a structure of a box body of a light emitting diode (LED) display screen. The structure comprises a box body and a plurality of LED modules, wherein the box body is made of an aluminum alloy material; a plurality of internally-recessed installation grooves are formed on one side face of the box body; splicing holes are formed on the peripheral side edges of the box body; the plurality of LED modules are respectively arranged in each installation groove; and the LED modules at the adjacent positions are connected with each other through latches. In the LED display screen, the aluminum alloy box body is manufactured by using a die casting molding process; the LED modules are directly fixed in the box body; four corners of each LED module are respectively connected with the adjacent LED module through the latches; after assembly of the structure, connection surfaces of four edges of the box body are aluminum alloy shell edges; the splicing connection of plastic parts is avoided; and the LED module can be highly protected in the transportation and detaching process. The structure of the box body of the LED display screen has the advantages of light weight, simple structure and good heat dissipation, and is convenient to install and maintain on site.
Description
Technical field
The present invention relates to display device, the LED display body structure that especially relates to a kind of PC of having face shield and dispel the heat good.
Background technology
LED display is to use high-tech display device very widely in recent years; Have screen intensity height, sharpness height, steady quality, but the life-span is long, Presentation Function is flexible and changeable, the characteristics of screen bulk area combination in any; Be very suitable for literal, figure, HD video constant pitch purpose broadcast propaganda; The outer indoors demonstration field that shows, it in addition occupied the status that other display device is not replaced.Owing to adopted the welding of up-to-date semiconductor material and high-tech automation equipment, the process means of assembling, the performance of LED to be greatly improved; Especially has the incomparable advantage of other display light source aspect color, brightness, the reliability, for the development of family, inside and outside display technique and product provides good basis.
At present, the LED production technology is increasingly mature, and domestic LED shows the industry dog-eat-dog; Increasingly matureization of control system, structure processing relies on the high finishing of CNC, for the high density LED display structurally provides reliable guarantee; The high-reliability electronic interface unit is also increasingly mature in the world; All kinds of video transmission modes are also increasingly mature, and compared to adopting the gigabit networking transmission mode, present HDMI, SDI etc. are more reliable; And can directly transmit high-definition video signal, the display performance of LED display is promoted greatly.
Development along with modern dance & art light technology; LED display be widely used in main background, wing flats, curtain; Canopy of the heavens equipment; This type of display screen all requires to have on-the-spot Fast Installation, fast quick-detach, install that flatness is high, that the slit is installed is little, and existing structure be mainly connect up and down fasten, simple and easy fillet snap close, with adjustment level and vertical side edge splicing gap.
The LED display casing uses cold rolled plate to carry out the can manufacturing welding fabrication in the prior art, and the technological process of its processing is: plate cutting-CNC punch press (or mould punching press)-bending-welding-polishing-plastic-blasting.A kind of mode is that the LED display casing is made the frame form, thereby adopts the moulding of integral die-cast aluminium; Another kind of mode is dismountable two parts before and after the LED display casing is made, and postnotum is assembled through different parts.Yet the whole one-piece construction of above-mentioned LED display casing is thick and heavy, and radiating effect is not good, and structure and shape is attractive in appearance inadequately.
Summary of the invention
Present LED display casing one-piece construction is thick and heavy, radiating effect is not good in order to solve, be difficult to assemble the technical matters of maintenance, and the present invention proposes the LED display body structure that a kind of one-piece construction is light and radiating effect is good.
The present invention adopts following technical scheme to realize: a kind of LED display, it comprises: the casing of aluminum alloy material, a side of casing is provided with the mounting groove of a plurality of invaginatings, and casing around the assembly unit hole is set on the side; Be separately positioned on a plurality of led modules in each mounting groove, interconnect through snap close between the led module of adjacent position.
Wherein, said casing is the integral die-cast moulding.
Wherein, each led module has identical structure, includes: module body, and several LED light emitting diodes are set on the one of which side form the screen body, be arranged on the system circuit board between back shroud and the module body, and said snap close is arranged on the module body.
Wherein, led module also comprises: be arranged on the module body and the vertically disposed a plurality of lockholes of each snap close, each snap close respectively with the led module of adjacent position on the corresponding sealed connection of lockhole.
Compared with prior art, the present invention has following beneficial effect:
LED display of the present invention adopts compression molding process manufacturing aluminum alloy casing; Each led module directly is fixed in the aluminium alloy box behind the die cast; And each led module is connected with adjacent led module through snap close respectively; Four limit joint faces of this structure assembling rear box are the Al-alloy casing limit, do not exist the assembly unit of plastic parts to connect, and are high to the led module protectiveness in carrying and unloading process; Have easy for installation, convenient, in light weight, the simple in structure and good advantage of dispelling the heat of field maintemance.
Description of drawings
Fig. 1 is the structural representation of LED display of the present invention.
Fig. 2 is the structural representation of led module of the present invention.
Embodiment
As shown in Figure 1, the LED display that the present invention proposes comprises: the casing 1 of aluminum alloy material, said casing 1 is provided with the mounting groove 11 of a plurality of invaginatings, and casing 1 around a plurality of assembly units hole 12 is set on the side; A plurality of led modules 13, each led module 13 is installed among the mounting groove 11, and adjacent LED modules 13 mutual assembly units form an integral body.
In conjunction with shown in Figure 2; Each led module 13 has identical structure; Include: module body 131; Several LED light emitting diodes are set on the one of which side form the screen body, connection is provided with back shroud 132 on the another side, and system circuit boards such as power supply, control chip all are arranged between back shroud 132 and the module body 131; Be provided with on the module body 131 a plurality of snap closes 133 and with each snap close 133 vertically disposed lockhole 134.
Therefore, led module 13 through a plurality of snap closes 133 respectively with adjacent led module on the correspondence position lockhole sealed, thereby can the led module that be arranged in each mounting groove 11 13 be connected fast or dismantles, be convenient to I&M.
Because the positive integral die-cast of casing 1 becomes the mounting groove 11 of a plurality of depressed; In the mounting groove that fixedly is close to casing 1 11 that contains electronic components such as LED, drive IC that can the LED display divergence is the highest; Make heat that its work produces through heat conduction on the casing 1 that aluminium alloy compression casting forms, thereby be dissipated in the air fast.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
