Description

형광램프
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제7도는 충전가스압과 램프관의 내경의 값을 곱한 값과 램프수명(절대수명)간의 관계를 나나탠 도면,
제8도는 미세선의 직경과 램프전류간의 관계를 사용해서 본 발명에서 사용되는 미세선직경의 한계와 통상적인 디자인 기준간의 관계를 나타낸 도면,
제9도는 Ith/IL과 VK간의 관계를 나타낸 도면.

Claims (6)

  1. d cm의 내경을 갖는 램프관(101)과, 전기방전을 유지하기 위해서 P Torr의 압력으로 상기 램프관(104)에 충전된 가스(106), 상기 램프관(101)의 양쪽끝에 대칭되게 한쌍의 전극(104)이 설치되어 있고, 이 전극(104)중에서 적어도 하나가 열음전극모드에서 동작되며, 상기 압력 PTorr와 내경 dcm간에는 P×d≥13인 조건이 만족되도록 구성된 것을 특지응로 하는 50mA나 그 이하의 램프전류로 동작되는 얼음전극형 형광램프.
  2. 제1항에 있어서, 음전극단락전압(VK)이 VK≥15(V)의 관계를 만족시키도록 된 것을 특징으로 하는 열음전극형 형광램프.
  3. 제1항에 있어서, 열음전극모드에서 동작되는 전극(104)의 필라멘트가 2MG의 두께를 갖는 금속세선으로 되어 있는 것을 특징으로 하는 열음전극형 형광램프.
  4. 제1항에 있어서, 상기 가스(106)가 희소가스(rare gas; 예컨대 아르곤)로 되어 있는 것을 특징으로 하는 열음전극형 형광램프.
  5. d cm의 내경을 갖는 램프관(104)과, 전기방전을 유지하기 위해서 PTorr의 압력으로 상기 램프관(104)에 충전된 가스(106), 상기 램프관(104)의 양쪽끝에 대칭되게 한쌍의 전극(104)이 설치되고, 이 전극(104)중에서 적어도 하나의 전극이 열음전극모드에서 동작되며, 음전극단락전압을 VK라 할때, 상기 압력 P Torr와 내경 d cm 및 상기 음전극 단락전압(VK)간에는 P×d＜13, VK≤15(V), (VK-10) P×d≥7인 관계가 성립되도록 된 것을 특징으로 하는 50mA나 그 이하의 램프전류로 동작되는 열음전극형 형광램프.
  6. 제5항에 있어서, 상기 가스(106)가 희소가스(rare gas; 예컨대 아르곤)로 되어 있는 것을 특징으로 하는 열음전극형 형광램프.
