Abstract

본 발명은 점등관이 필요없는 전자식 형광램프의 구동화에 대한 것으로, 고전압트랜스(HT)를 구비한 램프구동회로(10)를 구성하여 상기 고정압트랜스(HT)의 2차측코일(T₂)과 형광램프(1)의 양측에 설치된 필라멘트(2)(3)와의 단선(한선) 접속이 이루어지도록 하여 양필라멘트(2) (3)를 통한 고전압방전으로 형광램프의 점등이 실시되도록 함으로써 점등시간이 짧게 이루어지도록 함을 물론 필라멘트의 수명과는 관계없이 램프를 반영구적으로 사용할 수 있도록 한 것이다.The present invention relates to the driving of an electronic fluorescent lamp that does not require a light tube, and constitutes a lamp driving circuit (10) having a high voltage transformer (HT) and a secondary coil (T ₂ ) of the fixed voltage transformer (HT). The lighting time is increased by causing disconnection (one line) connection with the filaments 2 and 3 provided on both sides of the fluorescent lamp 1 so that the fluorescent lamp is turned on by a high voltage discharge through both filaments 2 and 3. In addition to shortening, it is possible to use the lamp semi-permanently regardless of the life of the filament.
