Abstract
The utility model relates to an automatic brightness control device, specifically relating to an automatic brightness control device for an LED display. The automatic brightness control device for an LED display comprises an LED display, wherein a photosensitive sensor is arranged on the LED display; the signal output end of the photosensitive sensor is electrically connected with an A/D conversion module; the signal output end of the A/D conversion module is electrically connected with a processor; and the processor is electrically connected with a brightness control module. The automatic brightness control device for an LED display also has the functions of the normal LED display and can realize the brightness control for the LED display, thus saving electric power resource, reducing light pollution and improving comfort level for viewing the LED display for human eyes.
Description
Technical field
The utility model relates to the ABC device, particularly a kind of LED display ABC device.
Background technology
LED display does not all have to consider under indoor and outdoor and exterior ambient environment luminance brightness condition of different, to realize different brightness at present.Because eye is responsive especially to light, the brightness range of a sensation the most comfortable is arranged.If the brightness of LED display is invariable, the brighter place of light out of doors then, the people watches that LED display will compare painstakingly, and indoors or the darker place of light in evening, the people watches that LED display can think that again luminance brightness is too strong.Not only waste energy, run counter to " low-carbon (LC) " theme, human eye is not felt well, also might cause light pollution.
The utility model content
To the defective that exists in the prior art, the purpose of the utility model is to provide a kind of LED display ABC device, has the function of conventional LED display concurrently, again can real LED display brightness regulation, save electric power resource, and reduce light pollution.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of LED display ABC device; Comprise LED display; Be arranged on the light sensor on the LED display; The signal output part of said light sensor is electrically connected with the A/D modular converter, and the signal output part of said A/D modular converter is electrically connected with processor, and said processor is electrically connected with the brightness regulation module.
Further, in the said light sensor photoresistance is set, is used to gather brightness signal, it is highly sensitive, makes regulating device more accurate to the adjusting of brightness.
The brightness signal that said A/D modular converter collects according to above-mentioned photoresistance converts brightness signal to the electric signal that is directly proportional with light intensity.
Said processor is equivalent to the CPU in this regulating device, the power of above-said current signal is judged, and given said brightness regulation module with information transmission, and said brightness regulation module is exported optimum luminance brightness.
The described LED display ABC of the utility model device has the function of conventional LED display concurrently, can realize the LED display brightness regulation again, saves electric power resource, reduces light pollution, and the comfort level can improve human eye and watch LED display the time.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the connection block diagram of each functional module in the utility model.
Embodiment
For the creation characteristic, the technological means that make the utility model and reach purpose and be easy to understand and understand, further set forth the utility model below in conjunction with specific embodiment.
As depicted in figs. 1 and 2, the described LED display ABC of the utility model device comprises:
Wherein, In the said light sensor 1 photoresistance is set; Brightness signal is gathered in said photoresistance, because light sensor 1 output terminal is electrically connected the brightness signal that said A/D modular converter 2 collects according to photoresistance with A/D modular converter 2; Brightness signal is converted to the electric signal that is directly proportional with light intensity; Said A/D modular converter 2 is electrically connected with processor 3, and 3 pairs of A/D modular converters 2 of said processor convert the electric signal that is directly proportional with light intensity to be judged, and processor 3 is electrically connected with said brightness regulation module 4; Said brightness regulation module 4 is controlled the luminance brightness of LED display 01 output through the judged result of processor 3, the luminance brightness of output optimum eye.
The utility model is realized the LED display brightness regulation, saves electric power resource, reduces light pollution, and the comfort level can improve human eye and watch LED display the time.
More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
1. LED display ABC device; Comprise LED display; It is characterized in that: also comprise the light sensor that is arranged on the LED display; The signal output part of said light sensor is electrically connected with the A/D modular converter, and the signal output part of said A/D modular converter is electrically connected with processor, and said processor is electrically connected with the brightness regulation module.
2. LED display ABC device according to claim 1 is characterized in that: in the said light sensor photoresistance is set.
