Description

A kind of LED display of self-adaptation adjustment

Technical field

The utility model relates to the LED display technical field, particularly relates to a kind of LED display of self-adaptation adjustment.

Background technology

In recent years, be accompanied by the develop rapidly of LED technology, LED display has been applied in the every field of human lives or production, such as LED illumination, industrial display screen, mobile phone display screen etc.

At present, traditional LED display is made up of following technical characterictic mostly: by the LED display formed of LED luminotrons of a plurality of parallel connections each other or series connection, be the microprocessor that said LED luminotron provides the driving circuit of electric current and is used to realize said driving circuit is controlled; But the link of putting into practice through long-term finds that there is following defective in this traditional LED display: one, luminous intensity is constant, and is bigger to eye injury when the people closely watches LED display, when the people watches LED display at a distance, do not see Chu again; Two, luminous intensity is constant, so when the people left LED display, LED display was still worked, existing greatly can be with waste; Three, luminous intensity is constant, so when the people left LED display, LED display was still worked, has great light pollution.

Summary of the invention

The technical matters that the utility model will solve is: existing LED display is improved, provide a kind of and have that adaptivity is strong, energy savings, prevent the LED display of the self-adaptation adjustment of light pollution function.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:

The LED display of a kind of self-adaptation adjustment comprises: the LED display of being made up of the LED luminotrons of a plurality of parallel connections each other or series connection, be the microprocessor that said LED luminotron provides the driving circuit of electric current and is used to realize said driving circuit is controlled; It is characterized in that: also comprise the position transducer that is connected with said microprocessor, the analog signal output of said position transducer is connected with the simulating signal input block of said microprocessor.

As preferred version, the utility model has also adopted following technical scheme:

Said position transducer is a photoelectrical position sensor.

Said position transducer is the infrared electro position transducer.

The analog signal output of said position transducer is connected with the simulating signal input block of said microprocessor through behind the signal amplification unit.

The analog signal output of said position transducer is connected with the simulating signal input block of said microprocessor after through the noise filtering unit.

Advantage and the good effect that the utlity model has are: one, through in traditional LED display control circuit, increasing position transducer, realized that the self-adaptation of LED display brightness is regulated, had the advantage of protecting eyes, energy savings and preventing light pollution; Two, through adopting ripe photoelectrical position sensor and traditional LED display control circuit to combine, have characteristics simple in structure, easy to process; Three, through between position transducer and microprocessor, increasing signal amplification unit and noise filtering unit, improved the adaptivity precision of the utility model.
