碩士 === 國立暨南國際大學 === 光電科技碩士學位學程在職專班 === 101 === This thesis discusses the SoC applications Light Emitting Diode pulse driving and controlling the ambient temperature changes is still able to maintain electrical power and optical power output stable circuit architecture for the continuation of automatic electric power control system (Automatic Electronic Power Control, AEC) and automatic optical power control system (Automatic Photo Power Control, APC), the analog circuit control system extends digital automatic control system that uses a multi-function microprocessor as a control, and do not need to use the light sensor, the Light-Emitting Diode characteristics by changing the compensation voltage feedback control can achieve the power and stability, so that the light emitting diode and the optical power output of electric power under different temperature changes is still able to maintain a stable output, improve the efficiency of light-emitting diodes and the use of the value of time, and simplify the circuit structure, and the use of wireless transmission architectural features as the remote host to display information and control circuit operating mode, achieve multi-function wireless Light-Emitting Diode control system architecture.
