Abstract

The invention discloses an LED advertising lamp box, which comprises a frame, canvas mounted on the frame, and an LED back-light plate as well as a controller connected with the LED back-light plate in a matching way, wherein the LED back-light plate is an LED lattice board. The LED advertising lamp box controls the lighting on/off of LEDs on the LED lattice board through the controller, the lighting on/off areas can be set via patterns of the canvas, and a plurality of patterns can be displayed respectively, so as to achieve an animation effect. When the LED advertising lamp box is used for advertising, the display contrast gradient between the patterns and the ambient environment is improved, the pattern needing to be displayed is highlighted, the advertising effect is improved, and the lighting on/off areas are set by the controller, and good universality can be obtained.

Description

A kind of LED advisement lamp case

Technical field

The present invention relates to a kind of LED advisement lamp case, particularly relate to a kind of Intelligent luminous, illumination effect changes irregularly colorful LED advisement lamp case.

Background technology

The lamp box of prior art is substantially all possess to send single fixing flicker effect function or carry out timing luminescence by the fluorescent lifetime namely set in use, and this lamp box is with this fixing luminescence or be interrupted the luminous effect reaching lamp box; But for the functional structure of this lamp box, in use, fail the multi-level effect that lamp box is drawn to be presented by the continuous conversion of light emitting source, the lamp box of this structure structure does not possess this function.And the LED advisement lamp case of prior art generally includes: painting canvas, framework and LED-backlit plate.Painting canvas is the main body of display, and the pattern on painting canvas is for presenting the picture effect of LED advisement lamp case; LED-backlit plate LED makes light source, the advantage of specifically energy-conservation and convenient control.Framework is used to support painting canvas and LED-backlit plate.Such lamp box occurs in a lot of public place, is mainly used to advertise.In order to improve the effect of publicity, some technician have employed the brightness improving LED-backlit plate, this improves the contrast of lamp box and surrounding environment, but the effect of publicity increases limited, wastes energy more; Afterwards, some technician have employed and allow lamp box glimmer, and this technology improves more greatly the contrast of lamp box and surrounding environment really, but does not have good animation effect.

Summary of the invention

The object of the invention is the shortcoming in order to overcome above-mentioned prior art, a kind of Intelligent luminous, not only economize energy being provided but also having higher the effect of publicity and general LED advisement lamp case.

The technical solution adopted for the present invention to solve the technical problems is: a kind of LED advisement lamp case, and comprise framework, be installed on painting canvas on framework and LED-backlit plate, also include and mate with LED-backlit plate the controller be connected, LED-backlit plate is LED dot matrix plate.In the art, often just realize luminescence by painting canvas, framework and LED-backlit plate and flash, but adopt LED dot matrix plate as LED-backlit plate and adopt the technical scheme of the LED light on and off on controller control LED dot matrix plate not occur.This invention is by the LED light on and off on controller control LED dot matrix plate, and light on and off region according to the pattern setting on painting canvas, can show by several patterns respectively, forms animation effect, which achieves Intelligent luminous and the flickering effect of this LED advisement lamp case.

Further, the cell board that described LED dot matrix plate is connected by rectangular array forms, and every module unit plate is provided with LED.When LED is luminous, by the PLC technology set, luminous while the luminescence that can control separately each LED or the LED controlling every module unit plate, circulation is luminous, to reach multiple luminescent composition effect, presents intelligent luminescence; Utilize the light transmission features that lamp box is drawn, with light emitting source flash control outstanding lamp box draw in perhaps function.During whole lamp box work, the picture of Luminous display is very clear, and visual effect is splendid, and content color to be expressed is bright-colored, full of moving sense.

Further, every module unit plate is interconnected to constitute the LED dot matrix circuit be connected in length and breadth, and often row or every column circuits of LED dot matrix circuit are equipped with input and output port.

Further, described LED dot matrix plate forms the LED dot matrix circuit of multiple lattice luminous point.

In sum, the invention has the beneficial effects as follows: this LED advisement lamp case by the LED light on and off on controller control LED dot matrix plate, the pattern match on light on and off region and painting canvas, when this LED advisement lamp case makes advertising purposes, improve the display comparison degree of pattern and surrounding environment, highlight the pattern needing display, improve the effect of publicity, light on and off region is arranged by controller, versatility is good, and picture exhibition obtains very clear, and visual effect is splendid, content color to be expressed is bright-colored, full of moving sense.
