PURPOSE:To eliminate necessity of shortening of a luminescent tube even if a partition is installed by partitioning the inside of an envelope of lamp into a luminescent part and a nonluminescent part, and mounting a luminescent tube so that the center axis of the tube inclines toward the opposite side of the first bending part of the luminescent tube. CONSTITUTION:A partition 15 is installed inside an envelope 10 of a lamp. The inside of the envelope 10 is partitioned into a luminescent part 16 and a nonluminescent part 17. A luminescent tube 2 is mounted by a holder 20 so that the end 2d locates on the nonluminescent part side. The luminescent tube 2 is mounted aslant against the partition 15 so that the center axis O-O inclines toward the opposite side of the first bending part 2a. Thereby, interference of the first bending part 2a with the partition 15 is prevented, and necessity of shortening of the luminescent tube is eliminated. |
