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 advertising lamp box

Technical field

The present invention relates to a kind of LED advertising lamp box, relate in particular to a kind of Intelligent luminous, the colorful LED advertising lamp box of illumination effect change.

Background technology

The lamp box of prior art is substantially all to possess to send single fixing flicker effect function or come timing luminous by the fluorescent lifetime of namely having set in use, and this lamp box is fixed luminous or is interrupted the luminous effect that reaches lamp box with this; But for the functional structure of this lamp box, in use, fail the continuous conversion of the multi-level effect of lamp box picture by light emitting source presented, the lamp box of this structure structure does not possess this function.And the LED advertising lamp box of prior art generally includes: painting canvas, framework and LED-backlit plate.The main body of painting canvas for showing, the pattern on painting canvas is used for presenting the picture effect of LED advertising lamp box; The LED-backlit plate is made light source with LED, the advantage of concrete energy-conservation and convenient control.Framework is to support painting canvas and LED-backlit plate.Such lamp box occurs in a lot of public places, is mainly used to advertise.In order to improve the effect of publicity, some technician have adopted the brightness that improves the LED-backlit plate, do like this contrast that has improved lamp box and surrounding environment, and are limited but the effect of publicity increases, and waste energy more; Afterwards, some technician have adopted and have allowed lamp box glimmer, and this technology is the larger contrast that has improved lamp box and surrounding environment really, but there is no animation effect preferably.

Summary of the invention

The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, a kind of Intelligent luminous, not only energy savings but also higher the effect of publicity is arranged and general LED advertising lamp box are provided.

The technical solution adopted for the present invention to solve the technical problems is: a kind of LED advertising lamp box, and comprise framework, be installed on painting canvas and LED-backlit plate on framework, also include the controller that is connected with LED-backlit plate coupling, the LED-backlit plate is LED dot matrix plate.In the prior art field, often just realize luminous and flash by painting canvas, framework and LED-backlit plate, but adopting LED dot matrix plate not occur as LED-backlit plate and the technical scheme that adopts controller to control the LED light on and off on LED dot matrix plate.This invention is controlled LED light on and off on LED dot matrix plate by controller, and the light on and off zones can show respectively by several patterns according to the pattern setting on painting canvas, forms animation effect, this Intelligent luminous of just having realized this LED advertising lamp box with flash effect.

Further, described LED dot matrix plate is comprised of the cell board that rectangular array connects, and every module unit plate is provided with LED.When LED is luminous, by the control able to programme of having set, luminous when can control separately the luminous of each LED or controlling the LED of every module unit plate, circulation is luminous etc., to reach multiple luminous combined effect, presents intelligent luminous; The light transmission features that utilizes lamp box to draw is controlled with flashing of light emitting source and is given prominence to the interior perhaps function that lamp box is drawn.During whole lamp box work, the picture of Luminous display is very clear, and visual effect is splendid, and content to be expressed is colorful, and is full of moving sense.

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

Further, described LED dot matrix plate consists of the LED dot matrix circuit of a plurality of lattice luminous points.

In sum, the invention has the beneficial effects as follows: this LED advertising lamp box is controlled LED light on and off on LED dot matrix plate by controller, the pattern match on light on and off zones and painting canvas, when this LED advertising lamp box is made the advertising purposes, improve the display comparison degree of pattern and surrounding environment, given prominence to the pattern that needs demonstration, improved the effect of publicity, the light on and off zone is by the controller setting, versatility is good, and picture exhibition gets very clear, and visual effect is splendid, content to be expressed is colorful, and is full of moving sense.
