Abstract
The invention relates to a water-proof structure for an LED display panel. The water-proof structure consists of a rubber shell, LEDs, a circuit board, a press-in piece and a back panel, wherein the LEDs are fixed on the circuit board; the circuit board is positioned between the rubber shell and the back panel; and the press-in piece is arranged at the peripheral connection part of the rubber shell, the circuit board and the back panel. According to the invention, the vacuum-formed rubber shell completely wraps the LED circuit board to fully play a waterproof role, and meanwhile, the assembly and die costs are considerably lowered.
Description
Technical field
The present invention relates to a kind of LED display board waterproof construction.
Background technology
Known LED display panel production and processing mode has the lamp box of use or two kinds of ways of thin plate interlayer.The lamp box way is to be main with casing, perforate on panel, the LED transparency cover of packing into reinstalls the LED circuit board, or LED inserted in the transparency cover connects with electric wire, after cover backboard again.Thin plate interlayer way is perforate on structural panel, the LED transparency cover of packing into, and with the LED circuit board, backboard or glued membrane.More than two kinds of ways all be with the LED transparency cover; As method for packing, the adaptation of transparency cover and structural panel perforate is not enough, and the hole infiltration takes place; The rising-heat contracting-cold of casing internal volume air is prone in the water droplet inlet box; Problem such as peel off during interlayer way colloid low temperature, the barrier rate is higher admittedly to make now the mounted LEDs display panel, and the cost of the man-hour of assembling and material is more high simultaneously.In view of LED technology continuous evolution recent decades at present, brightness, luminescence efficiency; Color category, in serviceable life, characteristics such as lighting angle all have significant progress; And be widely used in TV, computing machine, light fixture; Outdoor traffic sign, traffic indication board, fields such as advertisement billboard.The application of display board out of doors; Be a LEDs to be connected with circuit board or electric wire; Be installed in fixing position, when lighting at the position display that is ranked in advance different pattern or literal, yet use out of doors; Waterproof and dampproof and sun-resistant method for packing just becomes important topic, and the present invention shows the new waterproof technology that proposes on the waterproof construction of the space of a whole page in this technical field with regard to LED.
Summary of the invention
The object of the present invention is to provide a kind of LED display board waterproof construction, the shell of transparent adhesive tape described in the present invention can complete coating LED display board, so can solve seepage problem.Want simultaneously to make large-scale plate face, be easy to assembling, with low cost.
The LED display board waterproof construction that the present invention proposes; Form by glue shell 1, LED 2, circuit board 3, pressing part 4 and backboard 5; Wherein: LED 2 is fixed on the circuit board 3, and circuit board 3 is between glue shell 1 and backboard 5, and the junction is provided with pressing part 4 around glue shell 1, circuit board 3 and the backboard 5.
Among the present invention, said glue shell 1 adopts the transparent adhesive tape shell, and thickness is 0.3mm-1.5mm, and material adopts polyethylene terephthalate (PET).
Among the present invention, said glue shell 1 is provided with and runs through shrinkage pool, and LED 2 stretches in the glue shell 1 through this shrinkage pool.
Among the present invention, glue shell 1 adopts vacuum forming technology to be made.
Among the present invention, said pressing part 4 adopts the pressing of widely used at present high frequency hot pressing technology.
Among the present invention, said pressing part 4 adopts the pressing bar.
The present invention mainly is the coating LED circuit board that the glue shell is complete; To reach complete good waterproof effect; High-weatherability PET material also protects internal circuit board and part to prevent the damage of sunshine and rainwater; The present invention simultaneously saves parts such as original LED transparency cover, adds the vacuum forming mould cost, has reached the demand that reduces cost.
Advantage of the present invention is following:
1. water proofing property completely.
2. cost is low.
3. the structural group dressing is prone to.
4. can make slim display board, thickness is lower than 3mm.
5. be easy to make the type matrix mode, each display board is a word monomer, can make up.
6. to different LED irradiating angle demands, only need select for use different LED to get final product, not influenced by the LED transparency cover.
Description of drawings
Fig. 1 is a structural diagrams of the present invention.
Fig. 2 is the embodiment of the invention 1 structural diagrams.
Fig. 3 is a partial assembly drawing of the present invention.
Label among the figure: 1 is the glue shell, and 2 is LED, and 3 is circuit board, and 4 are the pressing part, and 5 is backboard.
Embodiment
Combine accompanying drawing to further specify the present invention through embodiment below.
Embodiment 1: as shown in the figure, this structure is made up of glue shell 1, LED2, circuit board 3, pressing part 4 and backboard 5, and glue shell 1 adopts the transparent adhesive tape shell; Make the glue shell with vacuum forming, can make large-area plate face, LED2 and circuit board 3 are coated fully; Replace the LED transparency cover; Simultaneously the luminous emission angle of LED 2 only need select for use different LED 2 to get final product, and vacuum forming mould is cheap many than the plastics jetting mold; Simultaneously can make large-area circuit board 3 plate faces, 300cm x 900cm.
Transparent adhesive tape shell material is with the good material PET of weatherability (2. polyethylene terephthalate polyethylene terephthalate); The thickness of glue shell 1 is according to circuit board 3 sizes and LED 2 shapes simultaneously; Can select different-thickness 0.3mm to 1.5mm for use, glue shell 2 and circuit board 3 or backboard 5, the junction is with 4 pressings of pressing part all around; Pressing welds with the high frequency hot pressing, or with the press strip pressing.
