Claims (5)

  1. 내면에 형광체 피막을 형성한 관형 벌브(1)와, 이 관형 벌브 내부에 봉하여 넣어져 형광체 피막을 여기하는 자외선 발광물질과, 관형 벌브의 내부에 설치된내부전극(3)과, 관형 벌브의 바깥면에 관의 축방향을 따라 띠형상으로 밀착하여 설치된 외부전극(5)과, 이들 내부전극과 외부전극 사이에 전압을 인가하여 벌브 내부에서 방전을 발생시키는 방전 램프에 있어서, 벌브 내면에 형성한 형광체 피막은 벌브 표면의 휘도가 전체적으로 균일화 되도록 관의 축방향 위치에서 막의 두께를 바꾼것을 특징으로 하는 방전램프.
  2. 제1항에 있어서, 형광체 피막의 두께는 자외선의 여기가 약한 부분에서 형광체 피막의 투과율이 25-40%가 되며, 여기가 강한 부분에서는 형광체 피막의 투과율이 25% 미만 또는 40%를 넘도록 막의 두께를 변화시킨 것을 특징으로 하는 방전램프.
  3. 제2항에 있어서, 형광체 피막의 두께는 관형 벌브의 한쪽 끝에서 다른쪽 끝을 향하여 점진적으로 증가 또는 점진적으로 감소되는 것을 특징으로 하는 방전램프.
  4. 제3항에 있어서, 외부전극(5)은 관형 벌브의 한쪽끝 근방에 설치된 급전선(10)과의 접속부가 있으며, 이 관형 벌브의 한쪽끝 근방의 형광체막 두께의 투과율이 25% 미만 또는 40%를 넘으며, 관형 벌브의 다른쪽끝 근방의 형광체막 두께의 투과율이 25-40%인 것을 특징으로 하는 방전램프.
  5. 제4항에 있어서, 외부전극(5)과 급전선(10)의 접속부가 설치된 관형 벌브의 한쪽끝에는 내부전극이 위치하고 있는 것을 특징으로 하는 방전램프.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
