Abstract

본 발명은 마이컴 및 디지탈 기술을 이용하여 디지탈 디밍(DIMMING)식 전자안정기를 구현한 장치이다. 안정기 구동부에 마이컴을 채택하여 신뢰성을 상당부분 향상시켰으며, 소형, 경량화 및 전자안정기에 고기능을 부여할 수 있게 하였다. 조명의 질적 향상을 통한 사용의 편리성과 실내 전체 조도의 안정성이라는 단편적인 측면과 함께 에너지 절약 및 자원의 효율적 활용이라는 포괄적인 측면에서 다양한 활용성을 가진다. 외부 전압의 변동에도 안정기에 부여되는 구동펄스의 안정성을 유지하기 위하여 마이컴 제어 방식의 PLL(PHASER LOCKED LOOP)회로를 사용한 주파수 변조 방식을 채택하여 수백 단계의 자동디밍 범위를 구현한 것이 특징이다. 또한 안정기의 고기능, 고효율화를 위해서 외부 키 스위치나 리모콘에 의한 제어가 가능하도록 설계되었다. 외부 조도에 의해 실내 조명의 자동디밍 기능을 발휘할 수 있도록 마이컴에 수광센서를 붙일 수 있도록 하였고 인체감지센서를 사용하여 상황에 따라 램프의 ON/OFF동작에 사용한다.The present invention is a device that implements a digital dimming electronic ballast using a microcomputer and digital technology. The microcomputer is used in the ballast drive part to improve the reliability considerably, and it is possible to provide small size, light weight and high function to the electronic ballast. It has various applications such as energy conservation and efficient utilization of resources as well as a fragmentary aspect of convenience of use through improvement of lighting quality and stability of illumination of the entire room. In order to maintain the stability of the driving pulse applied to the ballast even in the fluctuation of the external voltage, it adopts the frequency modulation method using the PLL (PHASER LOCKED LOOP) circuit of the microcomputer control type and features an automatic dimming range of several hundreds. Also, it is designed to be able to control by external key switch or remote control for high function and high efficiency of ballast. A light sensor can be attached to the microcomputer so that the automatic dimming function of the indoor lighting can be performed by the external illumination. The human body sensor is used to turn on / off the lamp depending on the situation.
