The electrodeless fluorescent lamp is relatively new luminaire and has been known as the high energy saving lamp which has long life and environment-friendly. But these kind of lamps have some risks to cause harmful radio interference unavoidably due to its own inductive characteristics. In this paper we measured the radio disturbance characteristics of the induction lamp with the operating frequency at 250 kHz, and compared the values with the limits of relevant standards. Finally we have estimated the interference protection distance between the induction lamps and some services around their operating frequencies, and considered the desirable future scopes and limits of the applications for these kind of lamps.

조명에 사용되는 광원은 여러 가지가 있다. 백열등, 텅스텐 할로겐 램프, 형광등, 고압 나트륨등, 메탈핼라이드 램프, 고압 방전 램프, 등등 각 가지가 사용되고 있다. 각종 램프들의 성능이 꾸준히 개선되고 새로운 형태의 램프에 비하여 괄목하게 우수한 새로운 광원은 초고주파 방전을 이용한 무전극 방전등이 최근 각광을 받고 있다. 초고주파 방전에 의한 광원 기술은 전극을 사용하지 않기 때문에 조명 램프로서 많은 이점을 갖고 있으며, 따라서 그에 관한 연구개발이 오랫동안 추진되어 왔다. 특히 1990년대 초에 출현한 초고주파 방전에 의한 무전극 황전등은 조명 기술 분야에 새로운 획을 긋는 사건으로 많은 기대를 주었다. 최근에 한편으로는 제 2세대 kW-급 무전극 황전등의 출현이 예고되어 있고, 다른 한편으로는 100-W 급의 저출력 무전극 방전등이 개발되어 조명 뿐 만 아니라, 프로젝션 디스플레이, HDTV 등등, 첨단 정보표시 광원으로도 각광을 받고 있다. 본 논문은 초고주파 방전에 의한 광원 기술을 가능성을 보이는 저출력 신광원의 원리 및 응용에 관하여 논의하고, 앞으로 이 분야 산업 기술 전망을 조감해 본다.

This paper gives an assessment criteria and reliability improvement for high frequency power supply of high efficacy electrodeless fluorescent lamp. The electrodeless fluorescent lamp system consist of electrodeless fluorescent lamp, high frequency power supply and lighting fixtures. The high frequency power supply has a shortest life at the system. Therefore It is need th assess the Failure Rate or mean Time To Failure(MTTF) for the high frequency power supply of electrodeless fluorescent lamp system and improve the reliability at design. We suggest the assessment criteria and improve methods of the reliability on the design basis for the electodeless fluorescent system.

Characteristics of electrodeless lamp as a load of the ballast are different compared to normal fluorescent lamp because the lame includes an inductance due to coupling magnetics for inductive discharging process. This increased parameter makes the development of self-oscillation type ballast more complex and time consuming. Practical simulation method for an easy design of self-oscillation type ballast especially for Endura lamp, is presented by using a model and various analysis of simulation. Results of experiment are given for a verification of proposed method.
