Abstract
The invention discloses an LED (Light Emitting Diode) display device. The device comprises a PCB (Printed Circuit Board), an LED light source and a casing, wherein the LED light source is fixed on the PCB; the PCB is provided with a connection circuit inside for being connected with the LED light source; a plurality of buckles are arranged at the periphery of the back surface of the casing; an accommodating space for mounting the PCB is formed among the plurality of buckles; the PCB is mounted in the accommodating space through the buckles; the bottom of the accommodating space is leveled with the side edge of the back surface of the casing so as to expand the PCB outwards; the casing is provided with a light transmission hole opposite to the LED light source; and the front surface of the casing is covered by a sealing light transmission film. As the PCB is connected with the casing through the buckles, the device adopting the structure has the advantages of convenience for assembly, capability of dismounting, convenience for exchange or maintenance, simple assembly technique and low defective rate; and the PCB can expand, and the expanded PCB only needs one set of pins, so that wirings can be reduced.
Description
Technical field
The present invention relates to a kind of light-emitting diode display spare.
Background technology
Light-emitting diode display spare generally comprises pcb board, led light source and housing, existing light-emitting diode display spare generally adopts following methods to encapsulate, and led light source is fixed by welding on the pcb board, potting resin in housing again, pcb board is placed in the housing, seals with resin more at last.There is following defective in above-mentioned method for packing: when pcb board or housing break down can't work the time, whole light-emitting diode display spare can only be abandoned, can't carry out maintain and replace to it, cause holistic cost to increase; In encapsulation process, the light-emitting diode display spare of having filled resin must be toasted, because housing need pass through bake process, so that housing must adopt resistant to elevated temperatures material, increase cost of products; Simultaneously because this packaging technology is complicated, so that the defect rate of product is higher; Because pcb board is embedded in the housing, so that pcb board can not be expanded, each pcb board need be equipped with independently Pin pin; Encapsulation needs to use a large amount of resins, increases cost of products.
Summary of the invention
In order to address the above problem, the invention provides a kind of light-emitting diode display spare.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of light-emitting diode display spare, comprise pcb board, led light source and shell, led light source is fixed on the pcb board, be built-in with on the pcb board for the connecting circuit that connects led light source, the periphery at the described shell back side is provided with some buckles, form the accommodation space of the described pcb board of an installation between these some buckles, described pcb board is installed in this accommodation space by buckle, the side at the bottom of described accommodation space and the shell back side maintains an equal level, so that pcb board is to external expansion, corresponding led light source place is provided with light hole on the described shell, and described outer casing frontispiece covers and is provided with the sealed light-transmitting film.
Described light hole is provided with chamfering near the pcb board end.
Described buckle is arranged on bight, the shell back side.
The invention has the beneficial effects as follows: adopt the pcb board of the present invention of said structure to be connected by buckle with shell, need not adopt resin to encapsulate, reduce cost; Easy to assembly, can dismantle, be convenient for changing or safeguard, assembly technology is simple, and defect rate is low; Pcb board can be expanded, and the pcb board after the expansion connects a plurality of display devices only need arrange a cover Pin pin, can reduce wiring; Because shell 2 does not need through overbaking, can adopt the material of common material, reduce cost.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is assembling schematic diagram one of the present invention;
Fig. 2 is exploded perspective view of the present invention;
Fig. 3 is assembling schematic diagram two of the present invention;
Fig. 4 is that the present invention expands rear schematic diagram.
Embodiment
With reference to Fig. 1～Fig. 4, the present invention is a kind of light-emitting diode display spare, comprise pcb board 1, led light source and shell 2, led light source is fixed on the pcb board 1, be built-in with on the pcb board 1 for the connecting circuit that connects led light source, the bight at the shell back side 3 is provided with four buckles 4, form the accommodation space of an installation pcb board 1 between these four buckles 4, pcb board 1 corresponding buckle 4 positions are provided with breach or the through hole 8 that cooperates with buckle 4, pcb board 1 is installed in this accommodation space by buckle 4, the bottom 5 of accommodation space and the side at the shell back side 36 maintain an equal level, so that pcb board 1 is to external expansion, corresponding led light source place is provided with light hole 7 on the shell 2, and shell 2 positive coverings are provided with the sealed light-transmitting film, are used for substituting of the prior art resin-sealed.Adopt the pcb board of the present invention 1 of said structure to be connected by buckle 4 with shell 2, need not adopt resin to encapsulate, reduce cost; Easy to assembly, can dismantle, be convenient for changing or safeguard, assembly technology is simple, and defect rate is low; Pcb board 1 can be expanded, and the pcb board 1 after the expansion connects a plurality of display devices only need arrange a cover Pin pin 9, can reduce wiring, because shell 2 does not need through overbaking, can adopt the material of common material, reduces cost.
As shown in the figure, for the ease of assembling with pcb board 1, light hole 7 is provided with chamfering near pcb board 1 ends.
As shown in the figure, when shell 2 sizes during large or pcb board 1 expansion, can be at the shell back side buckle 4 be set around 3, for increasing strength of joint.
Above-described embodiment is preferred version of the present invention, and the present invention also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite of spirit of the present invention, the modification that these are equal to or replacement all are included in the application's claim limited range.
