Abstract
A LED single-point controllable backlight advertisement lampbox, relating to the technical field of the lampbox, sloves the technical problem that the prior lampbox can not prominently display small details in the advertisement picture, and when the advertisement picture is replaced, the position of the light source is necessary to be regulated to adapt the key characteristic needed to be displayed of the advertisement picture. The invention comprises a lampbox body, an advertisement picture, a light-diffusing plate, a light source and a controller of controlling the light-emitting mode of the light source, characterized in that the light source is a LED matrix backlight plate arranged behind the light-diffusing plate, the advertisement picture, the light-diffusing plate and the LED matrix backlight plate are sequentially arranged in the lampbox body from the front to the rear. By using the LED single-point controllable backlight advertisement lampbox, the invention is capable of prominently displaying details in the advertisement picture, and displaying characteristics according to different requirement of the advertisement picture without regulating the position of the light source, therefore the invention is convenient to be used.
Description
Technical field
The present invention relates to the technology of lamp box, particularly relate to a kind of technology of LED single point controllable backlight advertisement lamp house.
Background technology
Present advertising lamp box, all adopt fluorescent tube or LED lamp bar as backlight, and in lamp box, be provided with LGP, some also is provided with a controller that is used to control illumination mode, control by controller makes fluorescent tube or the LED lamp bar different blocks dynamic light-emitting at lamp box, has increased the demonstration effect of lamp box.But because fluorescent tube or LED lamp bar all can illuminate a bigger zone when luminous, can't give prominence to and show less details in the advertisement picture, and behind the replacing advertisement picture, the position that often needs to adjust light source is used very inconvenient to adapt to the emphasis feature of the required displaying of advertisement picture.
Summary of the invention
At the defective that exists in the above-mentioned prior art, the invention provides less details in the outstanding displaying of a kind of energy advertisement picture, and need not to adjust light source position can be according to its emphasis of demand Dynamic Display of different advertisement pictures, LED single point controllable backlight advertisement lamp house easy to use.
In order to solve the problems of the technologies described above, a kind of LED single point controllable backlight advertisement lamp house provided by the present invention, the controller that comprises casing, advertisement picture, light diffusing sheet, light source and control light source luminescent mode, it is characterized in that: described light source is the LED dot matrix backlight of being located at behind the light diffusing sheet, and advertisement picture, light diffusing sheet and LED dot matrix backlight are located in the casing from front to back successively.
LED single point controllable backlight advertisement lamp house provided by the invention, owing to used the light source of LED dot matrix backlight as lamp box, and can control optional position on the backlight by controller and light or extinguish, show less details in the advertisement picture so can give prominence to, and need not to adjust light source position can be according to its emphasis of demand Dynamic Display of different advertisement pictures, very easy to use.

The specific embodiment
Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
As shown in Figure 1-Figure 3, a kind of LED single point controllable backlight advertisement lamp house provided by the invention, the controller 5 that comprises casing 1, advertisement picture 2, light diffusing sheet 3, light source and control light source luminescent mode, it is characterized in that: described light source is the LED dot matrix backlight of being located at behind the light diffusing sheet 34, and advertisement picture 2, light diffusing sheet 3 and LED dot matrix backlight 4 are located in the casing 1 from front to back successively.
Be provided with base plate 6 in the described casing, LED dot matrix backlight 4 is located on the base plate 6.
As shown in Figure 4, during use, require the displaying according to advertisement picture 2 control documents of LED dot matrix backlight 4 illumination modes of establishment to copy in the general SD card earlier, starting model then is the controller 5 of DMX512, whether controller 5 detects the SD card automatically and exists, can't find SD card error information as not existing then to send, in time remind the staff to check whether SD is normal, as detect the SD card and have whether then detect in the SD card file available, then send the part error message of SD Cavan as unavailable, in time remind the staff to check the control documents that the SD card is interior, can be as file with then reading in SD Cavan part, then the control documents in the SD card is compiled as controller 5 used language, controller 5 is set according to the control of the illumination mode described in the control documents blinker is sent to the each several part control chip then, thereby flashes by chip controls LED dot matrix backlight 4.
