Abstract

본 발명은 형광등의 히터 이상시 이를 검출하여 전자안정기를 보호함을 물론 형광등의 수명을 연장시키기에 적당하도록 한 형광등의 전자안정기 보호회로에 관한 것으로, 종래의 전자식 안정기의 경우 형광등 내부의 히터가 과열되어도 이를 거출하여 히터를 보호해줄 회로가 없어 히터가 소손됨은 물론 심한 경우 안정기에 허용치이상의 부하가 인가되어 안정기가 파손되었으나 본 발명은 형광등(H)의 히터(H1)에 고전압을 인가하여 형광등(H)이 빠른 속도로 점등되게 제어하는 형광등 제어부(1)와, 상기 히터(H1)의 이상상태를 검출하여 펄스폭을 제한하므로 히터(H1)에 항상 정격전압이 인가되게 하는 보호회로(2)를 구비하여서 전자안정기를 보호해줄 수 있는 것이다.The present invention relates to an electronic ballast protection circuit for fluorescent lamps that detects when a heater of a fluorescent lamp is abnormal and protects the electronic ballast, and is suitable for prolonging the lifetime of the fluorescent lamp. even if there is no geochul the circuit will protect the heater this heater is doemeun burnout course severe is applied to the load more tolerance to ballast the present invention, but the ballast damage is a fluorescent lamp by applying a high voltage to the heater (H 1) of the fluorescent lamp (H) ( H) the protective circuit to be always applied with a rated voltage in a quick and speed fluorescent lamp control unit 1 that controls be lit to the heater (to detect the abnormal state of the H 1) limits the pulse width of the heater (H 1) ( 2) to protect the electronic ballast.

Description

형광등의 전자안정기 보호회로Electronic ballast protection circuit of fluorescent lamp

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 전자안정기의 보호회로도.1 is a protection circuit diagram of the electronic ballast of the present invention.

Claims (1)

형광등(H)의 히터(H1)에 고전압을 인가하여 형광등(H)이 빠른 속도로 점등되게 제어하는 형광등 제어부(1)와, 상기 히터(H1)의 이상상태를 검출하여 펄스폭을 제한하므로 히터(H1)에 항상 정격전압이 인가되게 하는 보호회로(2)를 구비하여서 구성됨을 특징으로 하는 형광등의 전자 안정기 보호회로.The fluorescent lamp control unit 1 controls a fluorescent lamp H to be turned on at a high speed by applying a high voltage to the heater H 1 of the fluorescent lamp H, and detects an abnormal state of the heater H 1 to limit the pulse width. Therefore, the electronic ballast protection circuit of a fluorescent lamp, characterized in that it comprises a protection circuit (2) to ensure that the rated voltage is always applied to the heater (H 1 ). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
