본 논문에서는 무전극형광등용 전원장치에 대한 전기적 및 광학적특성을 알아보기 위하여 성능측정을 수행하였으며, 무전극 형광램프의 고 수명에 대한 전원장치의 이론적인 평균고장수명을 알아보기 위하여 MIL-HDBK-217방법에 의한 예측방법을 이용하여 전원장치의 주위온도, 사용장소 및 설치조건에 따라 각 온도별로 각부품의 고장율을 예측하여 평균고장수명을 예측하였다. 그 결과 무전극형광등은 온도가 어느 정도가 유지되어야 광 효율이 좋은 반면 전원장치는 온도가 높으면 상대적으로 수명이 급격히 줄어들면서 특성이 열화하는 경항을 가진다.

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 to 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.

In Recent, it became necessary to develope the technology about electrodeless fluorescent lamp according to demand of the electodeless fluorescent lamp system that used higher efficiency and advantage of long-lifetime. Especially, in the electordeless fluorescent lamp which used H-mode, efficiency of lamp is decided from matching parameter of antena and inverter. So it is of the utmost importance to design antena and inverter Therefore, this paper used a transformer principle for efficiency rising of electrodeless fluorescent lamp and interpreted an equivalent circuit, used an impedance analyzer in order to confirm a performance enhancement of lamp along design of antenna, and confirmed parameter characteristic of R, L, C, Z, Q-factor along a change of magnetic flux density. Also, this paper confirmed a luminance characteristic of electordeless lamp along parameter change with measuring optical characteristic along a change of magnetic flux density

In Recent, it became necessary to develope the technology about electrodeless fluorescent lamp according to demand of the electodeless fluorescent lamp system that used higher efficiency and advantage of long-lifetime. Especially, in the electordeless fluorescent lamp which used H-mode, efficiency of lamp is decided from matching parameter of antena and inverter, so it is of the utmost importance to design antena and inverter. Therefore, this paper used a transformer principle for an efficiency rising of electrodeless fluorescent lamp and interpreted an equivalent circuit, and confirmed a luminance characteristic by ferrite change of antenna and change of coil turns. Also, this paper used the thermoelectric element which can let you cool ferrite and antenna and confirmed the luminance characteristic along a change of ferrite and an antenna temperature.
