Abstract

In this paper, we propose a energy-saving LED module using K-band microwave motion detecting sensor. To oscillate K-band microwave signal, An oscillator using a hairpin-type microstrip resonator was designed to increase stability and make fabrication easier. To radiate the microwave signal, a two-channel(TX/RX) patch antenna arrays was developed. Wilkinson power divider and ring hybrid mixer were developed and applied to obtain Doppler shift from the received signal. Shield cans were installed to protect the stability of the signals and unwanted external noise. The proposed motion detection sensor was mounted on a demonstration LED module and the energy saving performance through pre-test was verified.

본 논문에서는 실외용 움직임 감지에 적합한 K대역 마이크로파 움직임 감지 센서를 활용한 에너지 절감형 LED 모듈을 제안하였다. 헤어핀 형태의 마이크로스트립 공진기를 이용한 발진기를 설계하여 안정성을 높이고 제작이 쉽도록 하였다. 신호의 방사를 위해 송수신 2채널 패치 배열 안테나를 개발하여 적용하였다. 수신된 신호로부터 도플러 천이 값을 획득하기 위해 윌킨슨 전력분배기 및 링 하이브리드 혼합기를 개발하여 적용하였다. 신호의 안정성 및 원치 않는 외부잡음으로부터 보호하기 위해 쉴드 캔을 제작하여 장착하였다. 제안된 움직임 감지 센서를 실증용 LED 모듈에 장착하여 에너지 절감 성능을 모의실험을 통하여 검증하였다.
