Abstract
The utility model provides a light-emitting diode (LED) screen brightness control system. The LED screen brightness control system mainly solves the problem that the existing LED screen brightness control method can not regulate the screen intelligently in real time, so that viewers feel ill. The LED screen brightness control system utilizes a sensor in a light detection head to collect light data value around the outside of the LED screen for detecting surroundings brightness. An LED screen collector reads the collected data and feeds back to an upper computer provided with a controlling system. According to a set corresponding curve of ambient light and the screen light, the screen brightness can be regulated. The LED screen brightness control system achieves the functions of regulating automatically LED screen brightness according to different outside light, distributing and using the electric power reasonably.
Description
Technical field
The utility model relates to a kind of LED display automatic brightness-regulating system, is mainly used in that brightness automatically adjusts to LED display according to LED display working environment light intensity, belongs to the LED display control field.
Background technology
LED display is generally carried out work out of doors, and daytime or night surround lighting different, also different to the needed brightness of display screen.When environmental light intensity, LED display brightness also needs to lighten, and could be adapted to by human eye by day; When night, surround lighting was weak, need to reduce the brightness of LED display, just can not feel dazzling.
Existing LED display brightness adjusting generally is that the technician reaches the spot, and the brightness regulation mechanism of manual operation LED display has increased human cost like this, and is very inconvenient; In order to address the above problem, technician's time automatic setting brightness regulation of giving chapter and verse, but can not carry out real-time accommodation to display screen according to the variation of environmental light intensity.
The utility model content
The utility model provides a kind of LED display brightness control system, and mainly having solved existing LED display brightness adjusting method can't carry out in real time adjustment of intelligence to display screen, thereby causes watching the problem of personnel's discomfort.
Concrete technical solution of the present utility model is as follows:
This LED display brightness control system comprises controller, host computer and at least one photodetection head, be provided with sensor in the described photodetection head, the photodetection head be used for to gather the light intensity of LED display working environment, and light intensity data is sent to controller processes; Sensor in the described photodetection head is connected to form communication loop with controller and host computer successively, and host computer sends brightness regulated signal according to the light intensity data that receives to controller, and controller carries out brightness regulation to LED display.
Above-mentioned photodetection head is fixedly installed in the valid analysing range of LED display, generally is demonstration one side of LED display.
Above-mentioned photodetection head is evenly distributed in the valid analysing range of LED display, generally is demonstration one side of LED display.
Above-mentioned a plurality of photodetection head is preferably with the array mean allocation.
The utility model has the advantage of:
This LED display brightness control system utilizes the sensor in the photodetection head, gather the light data value of LED display outside ambient, in order to testing environment brightness, the LED display controller reads the data that collect, and feeds back to the host computer that control system is installed, according to the surround lighting of having set and the corresponding curve of display screen light, regulate brightness of display screen, it has realized the difference according to ambient light, automatically regulates the brightness of LED display, the function of reasonable distribution and use electric power.
Description of drawings
Fig. 1 is the utility model structure principle chart;
The accompanying drawing detail is as follows: the 1-LED display screen; The 2-sensor; The 3-controller; The 4-host computer; 5-photodetection head.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, as shown in Figure 1:
This LED display brightness control system comprises controller, host computer and at least one photodetection head, be provided with sensor in the photodetection head, form communication loop between sensor in the photodetection head and the controller, controller is connected with host computer, wherein a photodetection installation site should be as far as possible the same with the display screen direction, namely the photodetection head is fixedly installed on the LED display valid analysing range and shows a side, it is more that quantity is installed, degree of regulation is higher, concrete installation number user can adjust according to the real work situation, wherein take the array mean allocation as good.
Controller is to the order of losing one's life of photodetection hair, ask for the data that collect to the photodetection head, the photodetection head gathers the light intensity data around the LED display by sensor, the LED display controller reads the data that collect, feed back to the host computer that control system is installed, host computer obtains the data that the photodetection head collects, and carries out processing and identification, according to the surround lighting of having set and curve corresponding to display screen, revise brightness of display screen.
