Abstract

A LED displaying flashboard, which is simple and flexible, costs lowly, and can arbitrarily change the position of the LED according to the requirement of displaying information, comprises an upper layer insulating sponge, a negative electrode conductive metal mesh, a middle layer segregation insulating sponge, a positive electrode conductive metal mesh, a lower layer insulating sponge and so on. A long electrode of the LED for displaying is a positive electrode and can favorably thread the negative electrode conductive metal mesh and contact to connect with the positive electrode conductive metal mesh through a insulating rubber sleeve covering outside the long electrode. A short electrode of the LED is a negative electrode, and the length of the short electrode is merely long enough to contact and connect with the negative electrode conductive metal mesh and not long enough to reach to the positive electrode conductive metal mesh. The sponge plays the roles of insulating the positive and the negative electrode metal meshes and fixedly supporting the LED. Under the certain direct current voltage pressed from outside, the flashboard can display the information of letters or patterns and so on, can be utilized to produce the indoor-outdoor advertisement displaying board, the model exhibit board, the audio-visual teaching tool, the toy for children and so on.

Description

A kind of LED shows plate

Affiliated technical field

The utility model discloses a kind of simple and easy flexibly, low cost of manufacture, the LED that can arbitrarily change the LED position according to the display message needs show plate, is specially adapted to the inside and outside advertising display panel of make-up room, model Graphic Panel, object teaching apparatus and toy for children etc.

Background technology

Semiconductor light-emitting-diode (LED) display board such as large tracts of land picture and text show that full-color screen, state indicator board, sign illuminatian plate, indicator panel etc. are to utilize the LED, electronic circuit board and the sequence circuit that send shades of colour light to make.LED is the luminescent device that a class can be converted into electric energy visible light and radiation energy expeditiously.They have that operating voltage is low, power consumption is little, luminescence efficiency is high, stable and reliable for performance, in light weight, series of characteristics such as volume is little.LED kind row purple LED, blue led, green LED, yellow green LED, orange LED, red LED and White LED etc. that the information that is generally used for shows are multiple.But when making the above-mentioned LED display board that is used for literal or pattern displaying, LED normally utilize scolding tin fixedly welding on the electronic circuit board that has designed, once finishing the position that just can not change each LED easily, otherwise fragile LED and wiring board.Above-mentioned LED display board complex manufacturing technology of while, expense is higher, and is all the more so when particularly sequence circuit being arranged.

Summary of the invention

The purpose of this utility model be to avoid the weak point in the above-mentioned background technology and provide a kind of simple and easy flexibly, low cost of manufacture, can change the LED plate of LED display position as required and arbitrarily.

The technical scheme that its technical matters that solves the utility model adopts is: the plate parts are made up of upper strata the insulate sponge (5) etc. of sponge (1), negative electrode conductive metal mesh (2), middle level insulation sponge (3), positive electrode conductive metal mesh (4) and lower floor of insulating.The long pin electrode of the LED that is used for showing is positive electrode (6), and the electro-insulating rubber sleeve pipe that the outside is surrounded by can make it to pass smoothly negative electrode conductive metal mesh (2) and contact positive electrode conductive metal mesh (4).The short pin electrode of LED is negative electrode (7), and its length contacts with negative electrode conductive metal mesh (2) only and can not arrive positive electrode conductive metal mesh (4).Sponge plays insulation and isolates positive and negative electrode wire netting and fixed support LED.Depress at certain applying direct current, this LED shows that plate can good literal or the pattern of display design.When adding simple clock-pulse circuit, can also reach the effect that flicker shows.

The utility model is compared background technology following advantage:

(1) simple in structure.

(2) can change the display position of LED according to the needs of displaying contents easily and flexibly.

(3) low cost of manufacture.

(4) of many uses, but the inside and outside advertising display panel of make-up room, model Graphic Panel, object teaching apparatus and toy for children etc.

Fig. 2 is the pin synoptic diagram of LED of the present utility model.

Fig. 3 is the principle of work synoptic diagram that LED of the present utility model shows plate.

Among the figure: 1. upper strata insulation sponge, 2. negative electrode metallic conduction net, 3. middle level isolated insulation sponge, 4. positive electrode metallic conduction net, 5. lower floor's insulation sponge, 6.LED positive electrode pin, 7.LED negative electrode pin, 8. external dc power supply

Embodiment

With reference to figure 1, Fig. 2 and Fig. 3, adopt the LED pipe and the external dc power supply of commercially available insulation sponge, conductive metal mesh, electro-insulating rubber sleeve pipe, various glow colors.The thickness of insulation sponge is 1cm.The pore size of the mesh of conductive metal mesh should be able to allow the LED pin electrode that is surrounded by the electro-insulating rubber sleeve pipe pass through smoothly, and its density should be enough to make conductive metal mesh to contact with LED pin electrode and be connected simultaneously.The area of insulation sponge and conductive metal mesh is cut out according to the area of required demonstration.The number of LED and color are determined according to the literal and the pattern content of required demonstration.

Take following steps in the present embodiment: at first with reference to figure 1, insulate sponge (1), negative electrode metallic conduction net (2), middle level isolated insulation sponge (3), positive electrode metallic conduction net (4) and lower floor insulation sponge (5) of upper strata suppressed in order and fix, finish the making of plate parts.

Then with reference to figure 2, the long pin positive electrode (6) of LED is put the electro-insulating rubber sleeve pipe, the length of gum sleeve should be enough to make the positive electrode pin smoothly by negative electrode conductive metal mesh (2), and can not be in contact with one another.The short tube pin of LED is negative electrode (7), and contact is connected and can not reaches positive electrode conductive metal mesh (4) its length with negative electrode conductive metal mesh (2) only.

Then connection adds 5V direct supply (8), with reference to figure 3 positive and negative electrode of direct supply (8) is connected on respectively on positive electrode conductive metal mesh (4) and the negative electrode conductive metal mesh (2).Because the insulation buffer action of sponge, they can not the short circuit conducting.According to the literal and the pattern of required demonstration, the LED that is surrounded by the electro-insulating rubber sleeve pipe is inserted on the plate gets final product.Power supply positive electrode, positive electrode conductive metal mesh (4), LED positive electrode (6), LED negative electrode (7), negative electrode conductive metal mesh (2) and power-electrode then form the galvanic circle, LED is therefore luminous, thereby demonstrates literal or the pattern-informations such as sign, sign and signal that designs.When needs changed displaying contents, arbitrarily plug or conversion LED got final product.

In the present embodiment, LED shows that plate can be used for the indoor and outdoor advertisement and shows, as be made into the trade name board in trademark board, shop of commodity or indoor commodity introduce plate etc.This LED shows that plate also can be made into various displaying models, as building model, transport information situation model, museum's explanation model, military combat relief block etc.Simultaneously, this LED shows that plate also can be made into the object teaching apparatus, shows as information such as mathematics symbol, sign of operation, literal, picture, geometric figure, constellation.In addition, this plate also can be used for entertainment for children and knowledge learning, experiences the science of light, carries out Art Imagination creation etc.
