Abstract

본 형광등용 전자식 조광 안정기는 전기전자를 응용한 발명으로 형광등의 빛을 사용자가 원하는대로 할 수 없다는 기존의 고정관념을 깨뜨린 신기술이다.The electronic dimming ballast for fluorescent lamps is a new technology that breaks the existing stereotype that the user can not do the light of fluorescent lamps by the invention of electric electronics.

자체 비공식측정결과 일반안정기에 비해 50%의 절전효과를 볼 수 있고 또한 전자식 일반안정기에 비해서도 자동디밍시 약 20%을 절전효과를 볼 수 있다.As a result of its own informal measurement, it can save 50% of the power compared to the general ballast, and it can save about 20% when dimming automatically compared to the electronic ballast.

본 고안의 형광등용 전자식 안정기의 기술적 과제는 안정기에 부착되는 형광등의 수명을 연장하고 형광등의 수명말기때 발생되는 과전류로 인해 안정기의 회로파괴를 보호하기 위해 PUT 회로를 사용하였다. 그로인해 사용자의 실수로 오결선이나 과부하가 걸릴 경우에 자동으로 형광등이 소등되며 약 2~3초 후에 재점등시 정상적인 동작을 한다.The technical problem of the electronic ballast for fluorescent lamps of the present invention is to use the PUT circuit to extend the life of the fluorescent lamp attached to the ballast and to protect the circuit breaker of the ballast due to the overcurrent generated at the end of the lifetime of the fluorescent lamp. As a result, the fluorescent lamp will be turned off automatically if a user's mistake leads to incorrect wiring or overload.
