Claims (3)

  1. 가늘고 긴 관형으로 되어 있는 전구의 내부에 한쪽의 극성으로 되는 내부 전극을 설치하는 동시에, 이 전구의 외면에 축방향에 따라서 띠 모양으로 된 다른쪽의 극성으로 되는 외부 전극을 밀착 설치하고, 이들 외부 전극과 내부 전극의 사이에 고주파 전력을 인가함으로써 전구의 내부에서 글로우 방전을 발생하도록한 방전램프에 있어서, 전술한 외부전극의 폭을 축방향의 위치에 따라 바꾼 것을 특징으로 하는 방전램프.
  2. 제1항에 있어서, 전술한 외부전극의 폭은 이 외부전극의 폭을 균일하게 하였을 경에 발광 휘도가 낮아지는 곳의 폭을 넓게 한 것을 특징으로 하는 방전램프.
  3. 제1항에 있어서, 전술한 외부 전극의 폭은 중앙부를 좁게하고 양쪽 끝부분을 넓게 한 것을 특징으로 하는 방전램프.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
