Description
Technical field
The present invention relates to a kind of LED, specifically refer to a kind of LED display frame structure.
Background technology
In the middle of the application of resin bed luminescent characters, the structure of commercially common luminescent characters includes metal shell, LED light source and LIFT, and LIFT includes transparent injecting glue layer and color injecting glue layer from inside to outside.But, apply to stereo luminous character and the light belt in the fields such as a head, signboard, mark, all there is frame more or less in front, it is typically in the side of word when mounted to increase ear to be installed or arranges the form of bolt at side and be fixed on body of wall by luminescent characters, this kind of mounting means not only to be bored a hole on body of wall, and its installation procedure is also complex, under long erosion by wind and rain, the light-emitting area out-of-flatness of Luminous character can be caused, cause visual effect to decline；Also result in luminous site, front limited, can not completely represent enterprise's word and logo at night, it is impossible to meet and send out the normal work requirements of pipe word；When panel and frame connect situation degumming closely or between the two do not occur, easily intake at gap place into dirt so that the internal hydrops of luminescent characters causes the function reduction of LED light source or directly damages；Existing part resin bed word is in appearance close to similar effect, but surface is completed by resinous layer material, and weatherability is poor, the easy adhesive dust of product surface and foreign material, is placed on the outdoor easy variable color of use, has a strong impact on the service life of signboard.
Summary of the invention
It is an object of the invention to provide a kind of LED display frame structure, it is prevented that panel is connected with frame and does not closely cause that LED is intake into dirt, improves the service life of LED.
The purpose of the present invention is achieved through the following technical solutions:
A kind of LED display frame structure, framework including the rectangle of upper and lower both ends open, and the light-emitting area of described framework is transparent, the inwall of described framework shady face is provided with pcb board, multiple LED lamp source are longitudinally disposed side by side on pcb board, the framework inwall relative with LED lamp source is provided with resin bed, lighting cavity is formed between resin bed and pcb board, the upper groove of U-shaped is had in the both sides, top of lighting cavity, the both sides, bottom of lighting cavity have the lower groove of U-shaped, and baffle plate is arranged in groove and is sealed the upper end of lighting cavity by structure glue；Also include the base plate A and the base plate B that are hinged, and the movable end of base plate A and base plate B is respectively placed in lower groove.nullThe present invention is the improvement that existing LED lamp source is made，Existing LED lamp source includes metal edge frame，Its material is iron sheet baking vanish、Rustless steel、The metals such as aluminum，Framework is identical with traditional metal edge frame，The light-emitting area of the present invention is transparent，And the resin bed that LED lamp source can carry out optically focused is installed on the inwall of light-emitting area，And pcb board is arranged on the inwall of shady face，Pcb board forms a lighting cavity with resin bed，Top in lighting cavity，Namely the upper end of resin bed and the upper end of pcb board offer the upper groove of U-shaped，Baffle plate for sealing can in upper groove slidably，Fast and easy is installed，And when mounted，Baffle plate is sealed by the structure glue upper end being fixed in upper groove by lighting cavity，And in the upper groove of U-shaped, it is provided with the right-angle turning place of two 90 degree and a vertical junction，Considerably increase the connection area between baffle plate and resin bed and pcb board，Effectively block the entrance of external dust and moisture，Ensure the stability work of LED lamp source in lighting cavity，Extend its service life simultaneously；And the lower end of lighting cavity is sealed by base plate A and the base plate B being hinged, and the movable end of base plate A and base plate B is placed in the lower groove of U-shaped, gravity factor due to dust and moisture, it is seldom entered into inside lighting cavity by the bottom of framework, meanwhile also with contact area bigger between base plate A and base plate B and lower groove, the bottom of lighting cavity is closed, to avoid airborne dust or the toy etc. of minority to enter into inside lighting cavity, and the bottom of lighting cavity can be opened by the base plate A being hinged and base plate B by quick displacement, facilitate the service work of operator.
Further, on the inwall of both sides up and down of described lower groove roll be provided with ball, the movable end of base plate A and base plate B respectively with ball contact.When the movable end of base plate A and base plate B enters in lower groove; mutually would generally wear and tear with the inwall of lower groove; and produce bigger force of sliding friction; and then cause that the service life of resin bed and pcb board reduces; the inwall of both sides up and down of lower groove is provided with ball; the sliding friction between ball and base plate A, base plate B is made to become rolling friction; substantially reduce abrasion between the two; while realizing lighting cavity lower end quick closure, also improve the service life of inner components of the present invention.
Further, also include cable-through hole, be connected with external power source through cable-through hole by wire after multiple described LED lamp source parallel connections.Multiple LED lamp source are after parallel connection, then pass through wire to connect with outside power supply, the wire terminal avoiding multiple LED lamp source too much increases installation cost, and cable-through hole opens the shady face in lighting cavity, can effectively stop that the foreign material in the external world enter into inside lighting cavity, it is ensured that the luminous efficiency of LED lamp source.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention is when mounted, baffle plate is sealed by the structure glue upper end being fixed in upper groove by lighting cavity, and in the upper groove of U-shaped, it is provided with the right-angle turning place of two 90 degree and a vertical junction, considerably increase the connection area between baffle plate and resin bed and pcb board, effectively block the entrance of external dust and moisture, ensure the stability work of LED lamp source in lighting cavity, extend its service life simultaneously；
