る。SUMMARY OF THE INVENTION A ring-shaped fluorescent lamp of the present invention comprises a resin bulb having a ring-shaped bulb and a first member and a second member which are combined with each other to surround and connect both ends of the bulb. And a locking portion that is locked to a locked portion provided on the second member, and the locking portion is locked on the second member. And a regulating member for regulating the position of the engaging portion when the engaging portion is engaged.

かなので、コスト増を抑えることができる。According to this structure, even when the resin, which is the material of the base, is thermally deformed during lighting and the locking portion is about to be disengaged from the locked portion, the locking member causes the locking portion to move away from the locked portion. It can be prevented from coming off, and the locked state between the locking portion and the locked portion can be reliably maintained. That is, it is possible to further prevent the engaging portion between the engaging portion and the engaged portion from coming off due to thermal deformation of the resin that is the material of the base during the life of the lamp, as compared with the conventional annular fluorescent lamp. Moreover, unlike the conventional ring-shaped fluorescent lamp having a large reinforcing rib, the amount of resin used for providing the regulating member is small, so that the cost increase can be suppressed.

な環形蛍光ランプを実現することができる。Particularly, when at least one of the first member and the second member is provided with a reinforcing rib, the locking state of the locking portion and the locked portion can be reliably maintained by the regulating member. As a result, the reinforcing ribs can be thinned and the size of the reinforcing ribs can be reduced, so that the amount of resin used as the material of the die can be significantly reduced. Therefore, during the life of the lamp, it is possible to reliably prevent the locking portion between the locking portion and the locked portion from coming off due to thermal deformation of the resin that is the material of the base, and realize a low cost ring-shaped fluorescent lamp. can do.
