Abstract

The invention provides an LED soft light panel bearing meter for underground gates, which is used in the developed countries in the world currently. Most bearing meters for the underground gates in the world have adopted an LED display dot-matrix type, and illuminated figures are displayed through arranged LED dot matrices. The invention is characterized in that LED soft light panel display technology is adopted, and the baseplate of a display luminescent screen adopts a transparent organic glass board or a transparent plastic board or a plastic fiber board; illuminants of LED or LED patches are invisibly inlaid in the end faces on the peripheral hems of the baseplate. The luminous surface is perpendicular to the end faces. LED side light sources are adopted. The figures at the positions to be displayed on the surface of the baseplate are sprayed or silk-screen printed by using light materials. When LEDs give out light, the figure positions give out light. The thin positions without lighting materials do not give out light, and the figures give out light continuously. By adopting the invention, prior figures consisting of LED luminous points do not appear. The invention has the advantages of brightness, esthetic appearance, energy conservation and long life. The invention belongs to the technical field of an LED panel display.

Description

The LED lambency flat plate underground anchor gate bearing meter

Technical field

The present invention relates to a kind of subway gate LED lambency flat plate underground anchor gate bearing meter, belong to the LED technical field of flat panel display.

Background technology

Now be exactly the subway gate bearing meter of developed country in the world, though also show with LED, but also all be adopt the luminous composition of LED dot matrix needed current, no through traffic, suspend current figures, that advantage has been accomplished is energy-conservation, the life-span long, low-voltage, but shortcoming is a figure to be made up of piecemeal LED luminous point, not attractive in appearance, and the phenomenon that some luminous point does not work often appears, cause figure imperfect.

The invention provides a kind of LED lambency flat plate underground anchor gate bearing meter, advantage is long, low-voltage of more energy-conservation, life-span, and is more attractive in appearance, be luminous continuously, being that figure is that integral planar is luminous, or else is that piecemeal luminous point is formed figure, can not occur the incomplete phenomenon of luminous pattern again; The light that figure sends is softer and bright.

Summary of the invention

The purpose of this invention is to provide a kind of LED lambency flat plate underground anchor gate bearing meter, advantage is long, low-voltage of more energy-conservation, life-span, and is more attractive in appearance, and light is soft, bright.

Technical scheme is: the display lighting base board adopts transparent plexiglass plate or transparent plastic sheet or plastic optical fiber plate, light source adopts LED or LED paster, mode is that LED is set in the substrate-side end face, adopt the LED negligible amounts, shown figure position is at substrate surface silk-screen or spraying thin layer with lighting material, when the LED electrified light emitting, these figures that are printed on lighting material are luminous, and his position of base that is not printed on lighting material is not luminous.

The basic structure of LED lambency flat plate underground anchor gate bearing meter: the substrate 1 of display lighting plate is by transparent plexiglass plate (acrylic board) or transparent plastic sheet or the making of plastic optical fiber plate,

display light source

2,3,4 are respectively burn red, green light, the LED of sodium yellow inlays the into side end face of substrate 1, LED light-emitting area vertical substrate end face, substrate 1 lip-deep figure 5,6,7 constitute with lighting material silk-screen or spraying lighting material thin layer respectively, 8 is optical confinement layer between each graphic boards, 9 is control circuit, 10,11,12 are respectively

control circuit control

2,3, the energising control output end of 4LED.When 10,11,12 energising

control ends control

2,3 respectively, during 4LED, then spectrum is distinguished rubescent, green, sodium yellow for the LED that sends out red, green, yellow different colours, then substrate 1 lip-deep figure shows the red, green, yellow color of soft light respectively, and no through traffic, pass through, temporarily no through traffic then to represent the subway gate respectively.Thereby reach gate direction indicative function.

Description of drawings

Fig. 1, Fig. 2 are respectively the synoptic diagram of LED lambency flat plate underground anchor gate bearing meter different technologies scheme, and the numbering among the figure is consistent.

Shown in the figure:

1 is the display lighting base board;

2 LED or LED pasters for the burn red spectrum;

3 is the LED or the LED paster of green-emitting spectrum;

4 are spectrochrome LED of jaundice or LED paster;

5 symbols that are that no through traffic;

6 are current symbol;

7 are temporarily no through traffic symbol;

8 is optical confinement layer between each image substrate;

9 is control circuit;

10 are control red-light LED control circuit output terminal;

11 are control green light LED control circuit output terminal;

12 are control yellow light LED control circuit output terminal.

Illustrate: the difference of Fig. 2 and Fig. 1, three whole surfaces of substrate among Fig. 2 are to coat the daylighting material Material thin layer, LED electrified light emitting be entire plate rubescent, green, yellow light respectively among Fig. 2 then, and figure is with not doing Glue is cut and is slit into, the figure position is empty revealing, and other positions are not exposures, when the LED electrified light emitting, then The red, green, yellow coloured light figure that exposes respectively soft light, the same Fig. 1 of effect.

Good effect of the present invention: more energy-conservation, more eye-catching than existing in the world general subway gate direction, Figure is more attractive in appearance, the luminous pattern blind spot can not occur, and the life-span is longer, and the figure glow color is true to nature.

Embodiment

A kind of embodiment of LED lambency flat plate underground anchor gate bearing meter is: shear earlier and choose good transparent plexiglass plate of transparency or transparent plastic sheet or plastic optical fiber plate as the display lighting base board, the latent edge of substrate periphery end face advances LED or LED paster (LED or paster are welded on the printed circuit board (PCB) in advance), substrate surface is with the lighting material silk-screen or spray the figure of required demonstration, perform light between three luminous pattern substrates and isolate tipping more together, when LED switches on control circuit, then the figure of lighting material printing is luminous, and the light figure is soft bright.

Another kind of embodiment is: substrate surface is printed to thin layer with lighting material entirely, figure is to cut system with adhesive sticker, be figure cut make empty, other positions still have adhesive sticker, and other positions make that light isolates, though when LED electrified light emitting substrate surface full-luminous, but remove other positions at figure position owing to there is light to isolate, then a figure place is luminous, and the light outside at other positions be can not see, and has only the luminous soft bright ruddiness in figure position or green glow or gold-tinted.

Another kind of embodiment is: the surface of substrate is printed to dense site formula with lighting material, and one deck optical diffusion film is covered on its surface again, and other manufacture crafts are with above-mentioned embodiment.

Another kind of embodiment is: the figure of substrate is made of the engraving way.

Another kind of embodiment is: the figure of substrate surface forms with the injection moulding way.

Another kind of embodiment is: the figure of substrate surface extrudes dense netted pin hole with mold hot and forms, and the surface adds one deck optical diffusion film again.
