碩士 === 國立雲林科技大學 === 電機工程系 === 102 === The thesis develops an adjustable illumination to match the needs of the workplace. The system uses the Holtek HT46R24 single-chip as the controller and replaces the traditional incandescent light-emitting diodes (LED-Light Emitting Diode). Using of light sensors to detect the environment illumination and uses pulse width modulation PWM method(Pulse Width Modulation) to adjust the LED current and brightness of the light source autonomously. The system can maintain the comfortable illumination eye for the feeling of the people. Moreover this system can measure and display the actual values of temperature and humidity for the detected environment. The system can note the influence of the light for on the environmental for the people life.
