Abstract
The utility model discloses an LED display screen improved structure of an outdoor SMD and solves the technical problem that an LED display screen of the outdoor SMD can prevent water and is convenient for repair. The technical scheme is as follows: the LED display screen improved structure of the outdoor SMD comprises a back shell; a PCB board is assembled inside the back shell; a face cover is connected with the PCB board; and a water-proof cover is arranged between the PCB board and the face cover. Compared with the prior art, the improved structure adopts the water-proof cover to cover the PCB board, thus playing a water-proof effect without affecting light effect and has no large number of water-proof glue needed to be winkled, thus being convenient for repair.
Description
Technical field
The utility model relates to a kind of LED display, the structure-improved of the LED display of especially a kind of outdoor SMD with water-proof function.
Background technology
The LED outdoor display screen adopts the LAMP fluorescent tube usually, but the LAMP fluorescent tube can't be accomplished less spacing because itself size is bigger, and pel spacing 10mm has been the limit of LAMP usually.And SMD (Surface Mounted Devices surface mount device) is though fluorescent tube itself has less size, can accomplish the indoor screen (as 4mm) that pel spacing is less, and the design of current outdoor LAMP fluorescent tube display screen and manufacturing process are after the assembling of PCB and drain pan is finished, doing encapsulating on PCB handles, substantially all the shortcoming below existing: 1, quite inconvenience of the maintenance of product behind the encapsulating, need pick out marine glue, repair behind the components and parts again encapsulating again; 2, owing to the size restrictions of LAMP fluorescent tube, outdoor LED display screen adopts LAMP fluorescent tube minimum spacing only can accomplish 10mm, and adopts the SMD fluorescent tube still not have ripe design and manufacturing process, makes that the water-proofing treatment of open air is a difficult problem all the time.
Summary of the invention
The purpose of this utility model provides the structure-improved of the LED display of a kind of outdoor SMD, and the technical matters that solve is to make that the LED display of outdoor SMD can waterproof, and easy to maintenance.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: the structure-improved of the LED display of a kind of outdoor SMD, comprise drain pan, and be assembled with pcb board in the described drain pan, connect face shield on the described pcb board, be provided with bucker between described pcb board and the face shield.
Bucker of the present utility model be provided with pcb board on the identical projection of LED quantity.
Bucker of the present utility model is transparent PC material structure.
Face shield of the present utility model is a network.
The utility model compared with prior art adopts the waterproof cover cap on pcb board, makes it possible to play waterproof effect, does not also influence the effect of light, no longer need pick out a large amount of marine glues when keeping in repair simultaneously, keeps in repair more convenient.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is a perspective exploded view of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, structure-improved for the LED display of the outdoor SMD of the utility model, comprise drain pan 1, the upper end of described drain pan 1 is provided with pcb board 2, described pcb board 2 is provided with the bucker 3 of transparent PC material, bucker 3 is provided with and the identical projection 31 of LED quantity on the pcb board 2, described bucker 3 covers on outside the pcb board 2, LED then covers in the projection 31, the upper end of described bucker 3 is provided with face shield 4, face shield 4 is a fenestral fabric, and its number of grid is identical with the quantity of projection 31, and this face shield 4 is enclosed within on the bucker 3.
The utility model shelters from pcb board, thereby reaches the purpose of waterproof by at pcb board outer cover last layer bucker, does not influence the effect of light simultaneously, and the operation of removing encapsulating during installation from no longer needs to pick out a large amount of marine glues during maintenance, makes that maintenance is convenient.
