Abstract

In this paper, the luminance and resistance from different electrode materials of external electrode fluorescent lamp are measured and analyzed. New materials and process technology of external electrode are very important for the developed characteristics in lamp fabrication. This experiment, three different types for the forming of external electrode are Cu and Al taping, silver paste, Ni and Cu electrode-less plating methods. In the measurement of luminance, the results of brightness by Ni and Au plating methods for the external electrode on lamp glass are presented and also compared with the results by the methods using different electrode materials. The measured resistance values of Ni and Au plating process showed a little bit higher than that of silver paste process in spite of developed results of brightness. The Ni and Ni/Au plating processes are demonstrated best results and also showed a little bit different brightness due to different previous surface etching treatments.

본 논문에서는 다양한 전극재료로부터 빛의 밝기와 저항을 측정분석 하였다. 외부전극의 새로운 재료와 공정기술은 램프제작에서 개선된 특성을 위해서 매우 중요하다. 본 실험에서는 외부 전극을 형성하기 위한 다른 세가지 타입은 구리와 알루미늄 테이핑, 은 접착, 니켈과 구리의 무전해 도금 방법들이다. 밝기측정에서 램프유리위에 외부 전극을 위한 니켈과 금 플레이팅 방법에 의한 휘도의 결과를 나타내었고, 또한 다른 전극재료를 사용한 방법에 의한 결과를 비교 하였다. 니켈과 금플레이팅 공정의 측정된 저항값은 휘도의 개선된 결과에도 불구하고 다소 높은 저항값을 나타내었다. 니켈과 니켈/금 도금방법은 가장 좋은 결과를 나타내었고, 사전 표면 식각에 따라 약간의 다른 휘도를 나타내었다.
