Description
Technical field
The utility model relates to LED display application field, particularly relates to a kind of intelligent LED display.
Background technology
In recent years, along with the develop rapidly of LED technology, LED display has been applied to the every field of human lives or production, such as illumination, industrial LCD, mobile phone display screen etc.
At present, traditional LED display is made up of following technical characteristic mostly: the LED display be made up of multiple LED in parallel or series connection each other, to provide the driving circuit of electric current for described LED and for realizing the microprocessor controlled described driving circuit, following technological deficiency is existed for traditional LED display: because LED display brightness constancy is constant, in the place that ambient light is brighter, human eye viewing LED display can think that brightness is too low; And when dark, people soon LED display can think that brightness is too high.
Utility model content
The utility model provides a kind of intelligent LED display, solves LED in prior art and controls inconvenient, the inflexible technical matters of switch arrangement.
The purpose of this utility model is achieved through the following technical solutions:
A kind of intelligent LED display, comprise LED display 1, driving circuit 2, microprocessor 3, range sensor 4 and light sensor 5, described driving circuit 2 is connected with described microprocessor 3 by luminance adjustment module 6, and described range sensor 4 is connected with described microprocessor 3 by ADC modular converter 7 with described light sensor 5.
Technique effect of the present utility model is: LED display environmentally brightness and beholder's distance can carry out brightness regulation automatically, saves electric power resource, and comfort level when can improve viewing LED display.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model discloses a kind of intelligent LED display, comprise LED display 1, driving circuit 2, microprocessor 3, range sensor 4 and light sensor 5, described driving circuit 2 is connected with described microprocessor 3 by luminance adjustment module 6, and described range sensor 4 is connected with described microprocessor 3 by ADC modular converter 7 with described light sensor 5.
Wherein, overcurrent protection module is included in described driving circuit 2.
Arrange photoresistance in described light sensor 5, described range sensor 4 is optical displacement sensor or linear proximity transducer or ultrasonic displacement sensor.
Wherein, described photoresistance gathers brightness signal, because light sensor 5 is connected with ADC modular converter 7 with range sensor 4 output terminal, the brightness signal that described ADC modular converter 7 collects according to photoresistance and range sensor 4 and distance signal, brightness signal and distance signal are converted to the electric signal being directly proportional to light intensity and being inversely proportional to distance, described ADC modular converter 7 is connected with microprocessor 3, what described microprocessor 3 pairs of ADC modular converters 7 exported is directly proportional to light intensity and judges with the electric signal that distance is inversely proportional to, and microprocessor 3 is connected with described luminance adjustment module 6, described luminance adjustment module 6 is controlled the electric current that driving circuit 2 exports by the judged result of microprocessor 3, and then control the luminance brightness of LED display 1, export the luminance brightness of optimum eye.
The utility model realize LED display environmentally brightness and beholder distance automatically carry out brightness regulation, save electric power resource, and can improve viewing LED display time comfort level.
Be understandable that, the system architecture shown in figure does not form the restriction to system, can comprise the equipment more more or less than diagram, or combine some equipment, or different deployed with devices.
Above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
