Description

방전광원용 전극
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본원 발명의 일실시예에 의한 방전광원을 전극의 단면도,
제2도는 제1도의 방전광원용 전극의 LaB6에 대한 Ba의 첨가량과 방전개시전압의 상대 변화를 나타내는 특성도.

Claims (2)

  1. 회가스를 봉입한 방전용기내에 금속도체가 설치되고, 이 금속도체상에 2차전자방출재료막이 형성된 방전 광원용 전극에 있어서, 상기 금속도체는 1-5㎛의 두께로 형성되고, 또한 상기 2차전자방출재료막은 LaB6에 0.01 내지 20몰(%)의 비율로 Ba를 첨가한 화합물로 형성되고, 그 두께가 0.5-2㎛로 설정되어 있는 것을 특징으로 하는 방전광원용 전극.
  2. 상기 2차전자방출재료막은 LaB6와, 이 LaB6에 대해 0.01-20몰(5)의 비율의 Ba와, 이 Ba에 대해 0.01-5몰(%)의 비율이 Ca로 이루어지는 화합물에 의해 형성되어 있는 것을 특징으로 하는 방전광원용 전극.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
