Claims

[Scope of utility model registration request]

Mercury and a rare gas are sealed in the airtight space formed by the outer tube and the stem to form a discharge space, and within the discharge space, an electrode is disposed at one end, the other end is open, and a phosphor is placed on the inner surface. In a fluorescent lamp which accommodates two U-shaped inner tubes coated with U-shaped inner tubes and uses the U-shaped inner tubes as a discharge path, a common discharge path is provided for the discharge path of each of the U-shaped inner tubes. A fluorescent lamp characterized in that three electrodes are provided in the discharge space.
