A fluorescent lamp, comprising:
- a first electrode section having a first filament;
- a second electrode section having a second filament;
- a fluorescent tube in which a fluorescent substance is applied on an inner wall of the fluorescent tube;
- a first structure of a non-conductor provided in the fluorescent tube;
- and
- a second structure of a conductor provided in the fluorescent tube,
- wherein the first structure and the second structure are provided between the first filament and the second filament;
- the first structure surrounds the first filament, and
- a distance between the first structure and the first filament is 5 mm to 20 mm.
A fluorescent lamp, comprising:
- a first electrode section having a first filament;
- a second electrode section having a second filament;
- a fluorescent tube for the producing a fluorescent emission in response to a discharge current flowing between the first filament and the second filament;
- a non-conductor structure provided in the fluorescent tube;
- and
- a member for movably supporting the non-conductor structure,
- wherein in the supporting member supports the non-conductor structure so that at least a portion of the non-conductor structure is moved out of the path of the discharge current during a predetermined amount of time following start of flow of a discharge current, and the supporting member supports the non-conductor structure so that the non-conductor structure is moved in the discharge current path after the predetermined amount of time following the start of flow of a discharge current.
