For realizing the object of the invention, following technical scheme is provided:
A kind of intelligent light control system is provided; It comprises optical sensor, microprocessor and the display that is used for testing environment brightness; This light sensors to luminance signal convert voltage signal into and send microprocessor to; The microprocessor utilization carries AD converter and converts said voltage signal into digital signal, and controls the brightness of display according to digital signal.
The present invention utilizes optical sensor to convert the different brightness of air-conditioning surrounding environment into the different voltages with different signal; This optical sensor can be passive optical sensors or active optical sensor.The brightness of passive optical sensors perception environment is reflected as its changes in resistance; According to ohm theorem, the passive optical sensors changes in resistance causes the variation of resistance R terminal voltage Vc; Different voltages with different signal Vc is directly exported in the variation of active optical sensor sense ambient temperature.
The present invention also provides a kind of intelligent lighting control method of using described intelligent light control system, and it comprises the steps:
(1) optical sensor is gathered ambient brightness information, and converts voltage signal into and send microprocessor to;
(2) microprocessor converts voltage signal into digital signal;
(3) initialize program according to said digital signal and brightness degree contrast, is confirmed the residing brightness degree of brightness of current environment with the brightness classification in the microprocessor;
(4) microprocessor is regulated the luminous time (duty ratio) in each light period of display according to the brightness degree of confirming, the brightness that comes driving display.
This microprocessor can be divided into 8 grades with voltage signal Vc, and display brightness also is divided into 8 corresponding grades.According to said digital signal and brightness degree contrast, confirm the residing brightness degree of brightness of current environment.
The per interval T of this microprocessor detects primary voltage signal Vc second, detects after n time and averages as current ambient brightness value.Wherein T, n can be according to the practical application values, like T=0.1, and n=18.
The contrast prior art, the present invention has the following advantages:
The present invention can effectively solve the low-light level under high-brightness environment of display constant brightness and be difficult for differentiating running state of air conditioner, and high brightness influences the problem that the user has a rest and sleeps under the low-light level environment through the automatic adjusting to display brightness.
