Claims

[Scope of utility model registration request]

A predetermined amount of mercury and a rare gas of several Torr are sealed in an airtight space consisting of a glass outer tube with a substantially circular cross-sectional shape and a substantially circular stem, and phosphors with different luminescent colors are placed on the inner surface. Three coated curved arc tubes having approximately the same shape are hermetically fixed with one end of each arc tube around each of the three electrodes disposed on the stem, and the other end of each inner tube is attached to the stem. A variable color fluorescent lamp is arranged approximately at the center of the arc tube and opened in the vicinity of another common electrode, and the three arc tubes are arranged such that the plan view of the arc tube is A variable color fluorescent lamp characterized in that it is arranged to form a substantially triangular shape.
