Abstract

본 발명은 매우 양호한 연색성과 플랜키안 로우키스상의 또는 그에 근접한 색점을 가지며 수은과 희가스를 포함하는 밀봉된 복사 전달 엔벨로프와 발공층을 구비한 저압 수은 방전 램프에 관한 것으로, 상기 발광층은 최대치가 470nm와 500nm 사이에 있으며 그 절반의 너비가 최대 90nm인 휘선대를 가지고 2가의 유로퓸에 의해 활성화되는 제1발광 물질과 주로 가시 스펙트럼의 적색 영역에 있는 적어도 하나의 휘선대를 가지며 2가의 망간에 의해 활성화 되는 제2발광 물질을 포함하고, 본 발명에 따라, 상기 발광층은 또한 그 최대치가 430nm와 490nm 사이에 놓이는 휘선대를 갖는 제3발광 물질과 주로, 520nm와 565nm사이에 놓이는 휘선대를 갖는 제4발광 물질 및 주로, 590nm와 630nm 사이에 있는 휘선대를 갖는 제5발광 물질을 포함하며, 이것은 상기 램프의 발광 효율이 매우 양호한 연색성을 유지하면서 상당히 증가되고 상기 발광층이 램프의 수명동안 감쇄되는 속도는 매우 감소되므로써 성취된다.
