Description
Technical field
The utility model relates to display device, especially relates to a kind of PC of the having face shield and the good LED display that dispels the heat.
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.
The utility model content
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 utility model proposes the LED display that a kind of one-piece construction is light and radiating effect is good.
The utility model 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; Be arranged on the led module outside surface and be fixed on the PC face shield on the casing.
Wherein, said casing is the integral die-cast moulding.
Wherein, each led module has identical structure, includes: module body is provided with several LED light emitting diodes and forms the screen body on the one of which side; Be arranged on the system circuit board between back shroud and the module body.
Wherein, led module also comprises: be arranged on the module body a plurality of snap closes and with the vertically disposed lockhole 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 utlity model has following beneficial effect:
The LED display of the utility model adopts compression molding process manufacturing aluminum alloy casing; Each led module directly is fixed in the aluminium alloy box behind the die cast; Add the PC face shield of protection type then at the outside surface of led module, and each led module is connected respectively through snap close with adjacent led module, the four limit joint faces that this structure is assembled rear box are the Al-alloy casing limit; Do not exist the assembly unit of plastic parts to connect; 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.
