Description

백열전구
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 백열전구의 한 실시예의 단면도. 제2도는 동일한 요부의 모형적 확대단면도. 제3도 및 제4도는 적외선 반사막의 광학특성의 스펙트럼.
* 도면의 주요부분에 대한 부호의 설명
1 : 전구 2 : 적외선반사막 2H : 고굴절율층(高屈折率層) 2L : 저굴절율층 5 : 필라멘트.

Claims (1)

  1. 관 형상의 투명 전구의 내외양면중에서 적어도 한쪽면에 고굴절율층과 저굴절율층을 서로 엇갈리게 겹쳐서 층을 이루어서된 가시광투과 적외선 반사막을 설치하고 또한 상술한 전구의 중심부에 텅스텐 필라멘트를 설치한 백열전구에 있어서, 상술한 고굴절율층의 광학막 두께는 0.21∼0.31μ이고, 또한 상기 저굴절율층의 광학막두께는 최상층의 것이 1/2×(0.21∼0.31)μ, 기타 층 중에서 적어도 하나의 층이 2×(0.21∼0.31)μ, 나머지의 층이 0.21∼0.31μ인 것을 특징으로하는 백열전구.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
