In this paper, we propose an efficient lighting control system design for AVR based LSDM control. This paper, an efficient lighting control system design for LSDM control be design divided as the signal control part for I/O data bus and the timer/counter part for clock signal control according to operating conditions. LSDM control logic be optimization to PORTx and DDRx register by specifying the logical value of each bit for effective control signal processing. And, the LSDM control signal by lighting control program execution of ATmega128 be designed to be LSDM lighting control by control logic operating. In this paper, a proposed lighting control system were measured to power loss rate to proved the power loss reduction about lighting status of LSDM control logic by download the lighting control program to system through serial from host PC. As a measurement result, a proposed lighting control system than the existing lighting control system were proved to be effective to the overall power consumption reduction.
