Abstract
The invention relates to a waterproof LED displaying module, which comprises a surface shell, a back shell and a circuit board. The surface shell and the back shell are locked to form a box structure and the circuit board is positioned within the box structure; a plurality of LED lamps are provided on the circuit board and a plurality of loopholes corresponding to the LED lamps are provided on the surface shell; the waterproof LED displaying module also comprises a gasket made from elastic materials, the gasket is detachably positioned between the surface shell and the circuit board with four sides thereof tightly fitted with the internal wall of the surface shell and is formed by injection moulding silica gel materials added with metal powder; the LED lamps penetrate through the gasket and are tightly fitted with the gasket. As the sealing is carried out by the replacement of perfusion sealant in the prior art with the gasket made of elastic materials, the waterproof LED displaying module of the technical proposal of the invention can be convenient for being demounted while sealing effect is guaranteed, thus facilitating the repair and maintenance. Moreover the waterproof LED displaying module of the invention not only effectively prevents water, but also realizes the shield effect.
Description
Technical field
The present invention relates to the image display technology field, be specifically related to a kind of Waterproof LED and show module.
Background technology
In recent years, the development of large scale display screen technology is rapid, and increasing large scale display screen appears at us at one's side.And present big screen display screen all has several LED to show that module combines, thereby the LED screen shows that module is the key of large scale display screen.Existing LED shows that module mainly comprises: a box-like back cover, and a tabular face-piece, both fasten the formation box body, and the circuit board that is pasted with a plurality of LED is housed inside among the zoarium.The light of LED can appear, and need offer the hole of some corresponding LED on face-piece, will make that like this rainwater easily enters.So it is encapsulating inside that existing Waterproof LED shows the way of module, the LED that circuit board surface is pegged graft is closed, and also makes the slit between circuit board and the back cover be filled and seal simultaneously, and the problem of bringing is non-dismountable, inconvenient maintenance.
Summary of the invention
Technical matters to be solved by this invention provides a kind of Waterproof LED and shows module, and it not only can waterproof, and is convenient to dismounting.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of Waterproof LED shows module, comprises face-piece, drain pan and circuit board, and described face-piece and drain pan fasten and constitute box body structure, and described circuit board is arranged in described box body structure; Described circuit board is provided with several LED lamps, face-piece is provided with the light hole of some corresponding LED lamps, described Waterproof LED shows that module also comprises the sealing gasket that resilient material is made, described sealing gasket detachably is arranged between face-piece and the circuit board, and with face-piece inwall wringing fit, described sealing gasket is that the silica gel material injection moulding that is added with metal powder forms around it; Described LED lamp passes sealing gasket, and keeps wringing fit with sealing gasket.
Adopt the Waterproof LED of technical solution of the present invention to show module, have following beneficial effect:
Because replacing pouring in the prior art fluid sealant, the sealing gasket that adopts resilient material to make seals, when guaranteeing sealing effectiveness, can be for convenience detach, thereby maintenance and easy to maintenance.But also in effective waterproof, realized shield effectiveness.

Below in conjunction with accompanying drawing Waterproof LED of the present invention is shown that module is described in further detail.
Embodiment
To shown in Figure 5, the Waterproof LED of this embodiment shows that module comprises: face-piece 1, drain pan 2, circuit board 3 and sealing gasket 4 as Fig. 1.Face-piece 1 and drain pan 2 all are the box body shape of an opening, and it forms a complete box body structure after fastening, and circuit board 3 and sealing gasket 4 promptly are arranged in described box body.Face-piece 1 is made the box body shape, rather than tabular, can be so that intensity improve greatly, thus make face-piece 1 not yielding.Circuit board 3 is gone into battle and is shown some LED lamps 31, has also offered some light holes 11 on the face-piece 1, the position of the corresponding LED lamp 31 in the position of light hole 11.Sealing gasket 4 is that silica gel material is injection molded, and the hole of some corresponding LED lamps 31 is arranged on it, and the undersized in described hole is in the size of LED lamp 31, and LED lamp 31 runs through sealing gasket 4 backs and spills from light hole 11.Sealing gasket 4 is used to replace fluid sealant of the prior art because sealing gasket 4 has certain flexible silica gel material and makes, and around it with face-piece inwall wringing fit, guarantee that water can not enter on the circuit board 3 around sealing gasket 4.LED lamp 31 inserts after the hole corresponding on the sealing gasket 4, and promptly closely contact, thereby have the better seal effect with its silica gel material on every side, and dismounting easily.
Prior art is generally sprayed conductive paint and is shielded around face-piece 1 and drain pan 2, but the complex process of spraying paint, bad control.The silica gel material that sealing gasket 4 adopts in this embodiment adopts electric silica gel also can realize shielding for adding the electric silica gel of metal powder, and technology is simple, control easily, and shield effectiveness is good.By Fig. 6 in conjunction with Fig. 3 to Fig. 5 as seen, the Waterproof LED of this embodiment shows module, and also the outside surface at shell 1 is coated with the conductive oil enamelled coating, and offers a plurality of connecting holes 12 on the sidewall around the face-piece 1.The sealing gasket 4 of conduction extends in the connecting hole 12, and contact and conducting with the conductive oil enamelled coating of shell 1 outside surface, and thereby can further strengthen shield effectiveness.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
