Abstract

In this paper, we implemented for the development of a high output induction lamp system, which lamp design is optimized by gas type, mixing ratio, pressure and discharge tube size, amalgam type and mixing ratio, and characteristics of ferrite core in the lamp. It's the circuit design by improving the power factor and efficiency according to the driving method, which has analyzing the characteristics according to the waveform and frequency. Finally, luminaries design part for applying the optimal lighting system considering the surrounding environment, the characteristics of the lighting circuit for electrodeless lamp has analyzed and the improvement has been proceeded. In conclusion, the driving frequency has optimized at 135kHz with degrading $7{\sim}10^{\circ}C$ based on the results of the optical characteristics of the induction lamp on peak noise FET(Q3,Q4) damage.

본 논문에서는 고출력 무전극 램프 시스템 개발에서 램프 내에 가스종류, 혼합비, 압력과 방전관 사이즈, 아말감종류 및 혼합비, 페라이트코어의 특성등의 최적화를 통한 램프 설계 부분을 연구하였다. 또한 구동방식에 따른 점등회로의 역율 및 효율개선, 파형이나 인가 주파수에 따른 특성 분석을 통한 점등회로설계 부분 등을 고려하였으며, 최종적으로 주변 환경을 고려 무전극 등기구 설계를 수행 하였다. 고출력 무전극 램프용 점등회로의 설계를 통한 특성분석을 진행하여 개선 보완을 통하여 효울을 향상 시켰으며 점등회로의 구동주파수에 따른 무전극 램프의 광학적 특성 및 시스템 영향을 확인한 결과, $7{\sim}10^{\circ}C$ 정도 낮은 특성의 135kHz로 구동하는 점등회로를 최적화하였다. 실험적으로 Peak Noise 발생으로 인한 FET(Q3,Q4) demage 현상을 개선하였다. 최종적으로 무전극램프용 점등회로 최종 설계도을 통해 약 2~3배 이상의 수명을 확보함으로써 안정기의 신뢰성 및 무전극 램프 시스템의 효율이 높음을 알 수 있었다.
