Abstract

The utility mode provides an LED display curtain, which is fabricated by transversely and longitudinally arranging a plurality of LED lamps at a certain interval; assembling on the front surface of soft high-strength fire-proof insulating fabric; fixing a controller and connection wire on the fabric back; and sewing a protection fabric layer on the fabric back for protecting the connection wires and the controller. The LED display curtain can be fixed on a frame to fabricate an LED display curtain module. When applied, the LED display curtains can be assembled and jointed into different sizes and shapes according to the requirement; the signal line and the power supply line of the controller on the LED curtain are connected; then the curtain is connected to a computer or other control device via a main signal line; and a power supply and a control program are started for displaying text and video images. When in an idle state, the curtains can be taken down, separated, folded and then arranged in a packing box for storage or transportation.

Description

A kind of LED shows curtain

Affiliated technical field

The utility model relates to a kind of device that can play literal and video image, the LED bulb especially can be installed on the curtain of softness play literal and video image, can flexural deformation, and the LED of unfolded shows curtain.

Background technology

At present, known LED display structure is with a plurality of light emitting diodes--LED, arrange according to certain spacing, be welded on the hard printed circuit board of certain size, perhaps a plurality of LED pixel bulbs are distributed and be installed on the hard fixed head of certain size, form the led display unit module, then led display unit module composite assembly is fixed, be assembled into the LED display of an integral body, connect power supply and control circuit board, play various literal and video image by computing machine or other control device.They have a common feature: be exactly the least unit of forming LED display--and the led display unit module all is a rigidity, can not bending fold and distortion, so general LED display screen body also is a rigidity, cannot flexural deformation, be made into three-dimensional shape or other is irregularly shaped very difficult, this gives and makes special-shaped LED display and bring very big inconvenience; Again because its volume weight is bigger, be difficult to whole Transporting, the display screen partition that needs during installation to debug is in advance packed, and is transported to the working-yard, again the LED unit that separates is shown that module re-assemblies debugging well, can come into operation, in case and installation is just very difficult mobile, uses if flow, and needs dismounting repeatedly to transport, this brings difficulty for the installation and the transportation of LED display, can consume great amount of manpower and material resources and financial resources.

And known curtain is a large scale cloth that launches to install, it can unfolded, flexural deformation, be mounted to irregularly shaped, but general curtain does not use LED to play the function of literal and video image, as stage curtain, can on curtain, stick static literal picture, but it can not play dynamic literal and video image; Film curtain and for example, though can the display text image, these character images are that projector throws up, are not that curtain itself plays back.

Summary of the invention

Existing LED display volume weight is huge, installation and transportation are difficult in order to overcome, flow to use inconvenience, can not flexural deformation and the deficiency of moulding difficulty, and existing curtain can not be play the deficiency of literal and video image, the utility model provides a kind of LED to show curtain, its volume is little, in light weight, both can unfolded, flexural deformation, composite assembly becomes various sizes and shape, can play literal and video image again; It can also be fixed on the LED that is made into different shape on the frame and show the curtain module, splice and combine use.Can launch easily during use to install, in the time of obsolete, it can be folded up, put into packing case, be convenient to transportation and collection.

The technical scheme that its technical matters that solves the utility model adopts is:

The high-strength fire-retardant of softness insulation weaving cloth or Polypropylence Sheet cutting are stitched into the curtain of certain size and shape, one side at curtain--positive according to certain line-spacing and row distance, laterally, vertically arrange a plurality of LED bulbs of installation, this LED bulb is that single or multiple red, green, blue three-color light-emitting diodes are installed in a transparent or translucent plastic casing--the LED composition, it is a cold light source, there is not heat, safe and reliable; LED bulb and curtain mechanical connection, it can be embedded in the curtain, also can be installed in the surface of curtain; Spacing between the bulb determines that as required it is relevant with the sharpness of image, and spacing is more little, and sharpness is high more.

Another side at curtain--controller is installed at the back side, controller and curtain mechanical connection; Each controller can be controlled horizontal, vertical bulb of some, and the quantity of controller determines that according to the sum of bulb controller and LED bulb are electrically connected; Controller receive to be handled the signal from computing machine, the brightness and the change color of control LED bulb, forward signal is electrically connected between the controller to next controller simultaneously, controller be connected the back side that electric wire is distributed in curtain.

One deck fire retardant insulating protection cloth is installed in addition at the back side of curtain, is covered connection electric wire and controller, shield, the LED that so just has been made into a softness shows curtain.Because all accessories all are fixed on above the soft curtain, so this LED shows that curtain also is can unfolded, diastrophic.

This LED is shown that curtain is fixed on rule or the erose frame, frame as square, arc or three-dimensional shape, the LED that can be made into multiple size and dimension shows the curtain module, and this module also can assembling combination become the LED of multiple size and dimension to show curtain.

During use, LED is shown curtain size and dimension splicing as required, be fixed on the mounting bracket, with the controller energized on the curtain, the controller on the curtain be connected to computing machine again by the resultant signal line, start power supply and control program then, the LED bulb is luminous, utilizes the principle of red, green, blue three primary colours colour mixture, just can play versicolor literal and video image, when not needing character image, can stop to play by control system.During dismounting, deenergization line and signal wire take off LED and show curtain, fold up and put into packing case, convenient collection and transportation.

The beneficial effects of the utility model are:

(1) the LED bulb can be installed on the cloth of softness, play literal and video image.

(2) this LED display screen can be arranged exhibits unfold folded, flexural deformation, composite assembly becomes various sizes and shape, is convenient to moulding and installation.

(3) LED can be shown that curtain is fixed on the frame of certain size and dimension, the LED that is made into standard shows the curtain module, is convenient to the splicing assembling.

(4) can be in air brushing on this curtain character pattern, when the LED lamp does not work, be static painting advertisement board; Can play character image when the LED lamp is bright, be dynamic electronic bill-board.

(5) can be used as common curtain and use, possess the function of LED electronic display simultaneously.

(6) can change the distribution density of LED bulb easily, thereby change the sharpness of writings and image.

(7) light emitting diode--LED is as light source, and the life-span is long, and power consumption is low, does not have heat, energy-saving safe in employing.

(8) volume is little, and is in light weight, and installing/dismounting is easy, is convenient to transportation and collection, is fit to very much flow and uses.

(9) simple in structure, processing and manufacturing is easy, and is easy to use.
