Abstract
The utility model relates to an outdoor surface-posted light-emitting diode (LED) display screen with improved protection performance, which comprises a casing. A printed board is arranged inside the casing, a luminous tube is connected with the outside of the printed board, and a face cover is arranged on the outside of the luminous tube. A gap is reserved between the edge of the printed board and the lateral wall of the casing, and a glue groove is arranged on the casing under the edge of the printed board. By means of the structure, double sealing can be formed, so that the LED display screen effectively prevents steam from entering the casing and improves the protection performance of the outdoor LED display screen.
Description
Technical field
The utility model relates to a kind of Surface Mount LED display, and especially a kind of outdoor surface welded LED display of improveing barrier propterty belongs to LED display technique field.
Background technology
The Surface Mount LED display be a kind of be the display screen of pixel with the Surface Mount luminotron, it shows various information through the display mode of control Surface Mount luminotron.
The acceptable encapsulating height of the used luminotron of outdoor surface welded LED display is lower, and its bondline thickness is about 1.3mm.After long-term the use, glue-line makes steam be prone to get into from the luminotron face because of thinner thickness chaps, forms the slit, causes protection to be lost efficacy.
At present, get into for fear of steam from the luminotron face, occurred sealing Treatment Technology scheme is also done at the printed board back side, but can produce following problem: (1) glue consumption significantly increases, and can increase the materials cost greatly; Need when (2) keeping in repair this adhesive layer strip off, very inconvenient; (3) this adhesive layer capacity of heat transmission is poor, can make printed board be difficult to heat radiation, influences properties of product.
The utility model content
The purpose of the utility model is: the problem to above-mentioned prior art exists, a kind of outdoor surface welded LED display of improveing barrier propterty is proposed, and improved barrier propterty, make protection more lasting.
In order to reach above purpose, the technical scheme of the utility model is following:
A kind of outdoor surface welded LED display of improveing barrier propterty comprises that positioned inside has the housing of printed board, and the said printed board outside is connected with luminotron, and the said luminotron outside is provided with face shield; It is characterized in that, leave the slit between said printed board edge and the housing sidewall; Said housing is provided with the glue groove below the printed board edge.
Elder generation's embedding bottoming glue in this glue groove during installation; Again with printed board put into housing and with the bottoming gluing jail; Then the place's embedding of the slit between printed board edge and housing sidewall silicon rubber cements silicon rubber respectively with printed board, bottoming glue, housing, and face shield is installed at last.So, silicon rubber and bottoming glue seamless binding form double seal, can avoid steam to get into housing better.
The further perfect technical scheme of the utility model is following:
1. said glue groove is positioned at the side-lower at printed board edge.
2. said glue groove is the endless groove that around printed board, is provided with.
3. said housing is equipped with O-ring seal away from the outside of printed board.
4. said luminotron is welded in the printed board.
After adopting the structure of the utility model, can form double seal, prevent that effectively steam from getting into housing, improved the barrier propterty of outdoor LED display screen.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the cross-sectional schematic of the utility model embodiment.
Fig. 2 is the schematic partial cross-sectional view of Fig. 1 embodiment.
Embodiment
Embodiment
The outdoor surface welded LED display basic structure of present embodiment improvement barrier propterty comprises that positioned inside has the housing 1 of printed board 2 shown in Fig. 1-2, printed board 2 outsides are welded with luminotron 3, and luminotron 3 outsides are provided with face shield 4; Leave slit 5 between printed board 2 edges and housing 1 sidewall; Housing 1 is at the side-lower at printed board 2 edges, be provided with ring-type glue groove 6 around printed board 2; Housing 1 is equipped with O-ring seal 7 away from the outside of printed board 2.
Elder generation's embedding bottoming glue 61 in ring-type glue groove 6 during installation; Again with printed board 2 put into housing 1 and with the bottoming glue 61 cement; Follow the slit 5 places embedding silicon rubber 51 between printed board 2 edges and housing 1; Silicon rubber 51 is cemented with printed board 2, bottoming glue 61, housing 1 respectively, face shield 4 is installed at last.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (5)
1. an outdoor surface welded LED display of improveing barrier propterty comprises that positioned inside has the housing of printed board, and the said printed board outside is connected with luminotron, and the said luminotron outside is provided with face shield; It is characterized in that, leave the slit between said printed board edge and the housing sidewall; Said housing is provided with the glue groove below the printed board edge.
