Abstract
Description
Claims (3)
- 서로 거의 평행하게 설치된 복수의 직관형 유리전구부(16)(17)가 굴곡부(18)에서 접속되어 방전로를 형성하고 내면에 형광체 피막이 입혀진 전구 본체(19)가 서로 나란하게 설치된 단부에 방전전극을 구비한 것에 있어서, 전술한 굴곡부(18)는 직관형 유리전구부(16)(17)보다 전구의 안지름이 작으며, 전구 본체(19)는 그 한쪽 끝 부분이 전구 본체(19)안으로 열린 수납부(23)가 있으며, 이 수납부(23)안에 아말감(24)이 수납되어 있는 것을 특징으로 하는 형광램프.
- 제1항에 있어서, 굴곡부(18)는 전구의 안지름이 양단부로부터 중앙을 향하여 점차적으로 축소되는 것을 특징으로 하는 형광램프.
- 제1항에 있어서, 수납부(23)는 소정 위치에 지름이 축소된 둑(25)을 설치하고 있으며, 이 둑(25)과 봉함단 사이에 아말감(24)이 유지되는 것을 특징으로 하는 형광램프.
