Description
[technical field]
The present invention relates to a kind of display device, refer in particular to a kind of LED and show the indoor demonstration module of PMMA type.
[background technology]
LED display has appeared in our the daily life, the streets and lanes in the city, and in the shop in front of the door, all there is their shadow in the hall in the bank hotel.But existing LED display structure all is overlapping and fixedly form through screw by drain pan, the pcb board that the LED lamp is set and face shield three-decker; And all LED lamps all are arranged on the pcb board of a monoblock; What add that face shield and drain pan all adopt is that plastics are processed; 3 kinds of materials all can have distortion, and it is exactly the bad problem with the color inconsistency of surface smoothness that there is maximum problems in the LED display that will cause this kind structured material to be processed thus.
[summary of the invention]
The objective of the invention is to overcome above-mentioned defective, provide the LED that a kind of flatness is high, colour consistency is good to show the indoor demonstration module of PMMA type.
The objective of the invention is to realize like this: a kind of LED shows the indoor demonstration module of PMMA type; It comprises drain pan, circuit board, led array and face shield; Led array is arranged on the circuit board, and its improvements are: the groove corresponding led array on face shield that is provided with corresponding embedded circuit board in the said drain pan is provided with through hole;
In the said structure, be provided with corresponding register pin and pilot hole between said drain pan and face shield;
In the said structure, it is dark-coloured that said face shield becomes, and its surface is handled through striped and formed texture;
In the said structure, said face shield is processed by acrylic;
In the said structure, said led array comprises LED particle and the driving circuit that separates setting, and the LED particle is arranged on the circuit board and through row's pin, mother row and connects driving circuit;
In the said structure, said circuit board comprises at least one into strips; Said led array comprises the LED particle, and the LED particle is arranged on every circuit board at interval;
In the said structure, the groove cross section in the said drain pan becomes upper surface to be wider than the trapezoidal of lower surface;
In the said structure, the through hole in the said face shield is made up of two parts up and down, and wherein lower shape is in the corresponding socket fixed L ED array that is used for of led array, and top is tubaeform exit facet.
Show the indoor demonstration module of PMMA type than common LED, beneficial effect of the present invention is the requirement of assembly unit between the installation of main consideration circuit board in the design and module.The led array mounting circuit boards is embedded in the face shield that drain pan and acrylic process; Promptly on drain pan, stayed the groove of mounting circuit boards, on face shield, offered the through hole of corresponding led array, correspondence is provided with register pin and pilot hole between drain pan and face shield simultaneously; Guarantee the error between drain pan and the face shield; And then can not increase under the too many condition of cost, make product integral body reach very high flatness, promptly the error between the module is no more than 0.1mm; The gap is no more than 0.03mm between the module, has satisfied the demand of practical application.
[description of drawings]
Below in conjunction with detailed description of the drawings concrete structure of the present invention
Fig. 1 is a structural representation of the present invention
Fig. 2 is a PCB modular structure synoptic diagram of the present invention
[embodiment]
Below in conjunction with accompanying drawing the specific embodiment of the invention is set forth in detail.
Like Fig. 1, shown in 2, the present invention relates to a kind of LED and show the indoor demonstration module of PMMA type, it is made up of drain pan 1, circuit board 2, led array and face shield 4.Different in traditional structure; In drain pan 1 of the present invention, be provided with groove 101, this groove 101 is used for embedded connection circuit plate 2, and circuit board 2 can receive in the groove 101 fully; And equal in drain pan 1 surface, best groove cross section can become upper surface to be wider than the trapezoidal of lower surface.Then corresponding led array is provided with through hole 401 on the face shield 4; Led array can be socketed in the through hole 401 of face shield 4 thus; Led array is arranged on again on the circuit board 2, also can be provided with corresponding register pin and pilot hole at face shield 4 and 1 of drain pan as required, and both unitized constructions are that drain pan 1 interlocks, rabbets circuit board 2 and led array therebetween with face shield 4 thus; One can prevent effectively that the three is out of shape the drawback of being brought thus, product structure is more stable.
Above-mentioned face shield 4 should adopt acrylic material to process, and the advantage of this material is a good planeness, the precise control of manufacturing dimension precision.Compare the face shield that tradition adopts plastics to process, adopt acrylic material to make face shield, its processibility and intensity all obviously are superior to plastics.Realize easily producing in enormous quantities.Face shield 4 forms through die casting; Strict controlling dimension tolerance in manufacture process; The best dead color (for example black or dark color) of also should doing is handled, and the striped processing is carried out on this external its surface, thereby forms texture (or claiming decorative pattern); Can effectively reduce the reflective of surface, strengthen the mixed light effect of display screen.And the through hole 401 in the face shield 4 can be made up of two parts up and down, and wherein lower shape is in the corresponding socket fixed L ED array that is used for of led array, and top is tubaeform exit facet.
Relative, drain pan 1 has a lot of brace rods usually, also register pin or pilot hole will be set simultaneously, and the processing technology more complicated uses acrylic material to realize that difficulty is bigger, therefore can still keep as required and adopt plastics as material.
In addition; Led array comprises LED particle 3 and the driving circuit that separates setting; Need to prove here, on circuit design, both separating structure that the present invention program's led array is made up of LED particle 3 and driving circuit; So through using single layer board 2 promptly to can be used as the mounted substrate of LED particle; And then circuit board 2 is connected with driving circuit with row is female through row's pin, the PCB of driving circuit can adopt two-sided or multiaspect PCB especially, designs the intensity of rigidity reinforcing section assurance entire product as required.So design can effectively solve the problem of chip for driving heat radiation, ensures the reliability of installing, and has also solved the maintenance difficult problem of present existence simultaneously.
Referring to Fig. 2; Further, circuit board 2 adopts many compositions of strip among the present invention, and the LED particle 3 of led array is set on every circuit board 2 at interval; How long groove 101 in the corresponding drain pan 1 also becomes strip; Every row is with one, can be with circuit board 2 plant face shields 4, drain pan 1 inside, and product can be conveniently when safeguarding gets final product 2 extractions of circuit board of required repairing.
In sum; The LED of structure of the present invention shows that the indoor demonstration module of PMMA type not only can guarantee the strict dimensional requirement of single module; The assembly unit between the module also makes not have matching problem between circuit board and drain pan, face shield, so also can be accomplished the scope that requires.Can effectively solve the problem in existing LED display assembly unit slit.
It is pointed out that to the invention is not restricted to above-mentioned embodiment, any simple modification, equivalent variations and modification that any professional and technical personnel of being familiar with does the foregoing description in based on technical scheme of the present invention all belong in protection scope of the present invention.
