Zusammenfassung:	The present invention relates to a method and system for dimming and power saving of LED group lighting lamps, which comprises: a control box control unit disposed in a control box for managing the system to include an alternating current (AC) voltage regulation unit for regulating a voltage of AC power into a certain voltage and supplying the certain voltage to a power supply line; and a terminal control unit disposed in each terminal of the system to include an AC voltage measuring unit for measuring an AC voltage on the power supply line and a terminal control unit for generating a dimming and power saving control signal having a form of a proper voltage or pulse width modulation (PWM), based on the measured AC voltage. According to the present invention, the control box control unit has an initial AC voltage modulation (stabilization) function and the terminal control unit has a line resistance compensation function. According to the present invention, instead of using complicated and high-cost communication such as powerline communication or radio frequency (RF) wireless communication from the control box to the terminal, an AC power voltage on the power supply line is modulated and then transmitted to the terminal and only the AC power voltage on the line is measured on each terminal to allow a lighting lamp to be dimmed to proper brightness and power to be saved, thereby providing simple and efficient dimming and power saving of LED group lighting lamps. 본 발명은 LED 집단조명등 디밍 및 절전 방법 및 시스템에 관한 것으로서, AC 전원의 전압을 소정의 전압으로 조절하여 전력공급 선로에 공급하는 AC 전압 조절부를 포함하며, 상기 시스템을 관리하는 제어함에 구비되는 제어함 제어장치; 및 상기 전력공급 선로의 AC 전압을 측정하는 AC 전압 측정부와, 상기 측정된 AC 전압에 기초하여 적합한 전압 또는 PWM 형태의 디밍 및 절전 제어신호를 생성하는 단말기 제어부를 포함하며, 상기 시스템의 각 단말기에 구비되는 단말기 제어장치;를 포함하는 것을 특징으로 한다. 본 발명은 제어함 제어장치에 초기 AC 전압 조정(안정화)기능과, 단말기 제어장치에 선로저항 보상기능도 포함한다. 본 발명에 따르면, 제어함에서 단말기까지 전력선통신이나 RF 무선통신과 같은 복잡하고 비용이 높은 통신수단을 사용하는 대신에, 전력공급 선로의 AC 전원전압을 조절하여 단말기로 보내고 각 단말기에서는 선로 상의 AC 전원전압만을 측정하여 조명등을 적절한 밝기로 디밍 및 절전을 할 수 있도록 함으로써, 간편하고 효율적으로 LED 집단조명등의 디밍 및 절전을 할 수 있는 효과가 있다.
