The double ring-shaped annular fluorescent lamp has a structure in which a small ring diameter arc tube and a large ring diameter arc tube are concentrically arranged and connected. However, accurate concentricity may not be achieved, and a stronger force in the ring radial direction or the like may act on each lamp holder. As a result, a force also acts between the base and the lamp socket of the double annular annular fluorescent lamp, which may cause breakage or poor contact. The object of the present invention is to reduce the force acting between the base and the lamp socket,
It is to alleviate the cause of breakage or poor contact.

At least one of the lamp holders 30 is of a slide type capable of moving in the ring radial direction of the double annular annular fluorescent lamp 20 without changing its direction. For this purpose, a slide mechanism 50 is interposed between the slide-type lamp holder and the fixture body 10. 1 to 3 will be supplemented. The lamp socket 40 functions as one lamp holder 30. In practice, it is appropriate to attach a fastener (spring piece) (not shown) to the lamp socket 40 and use the entirety as one lamp holder 30. Each of the remaining lamp holders 30 is of a spring piece structure having a deformed C-shape as a whole. 1 to 3, the slide mechanism 5 is provided on the lamp socket 40 (one of the lamp holders 30) side.
Apply 0. The slide mechanism 50 has a structure in which an edge of a slide hole 51 extending in a radial direction of a ring on the appliance body 10 side is slidably engaged with a slide groove 52 on a base side of the lamp socket 40. Small ring diameter arc tube 21 / Large ring diameter arc tube 22
If the gap between them is not uniform or if there is an error in their ring diameter, a force acts between the lamp socket 40 and the base 29. This force acts mainly in the radial direction of the ring. At this time, the slide mechanism 50 works to correct the position of the mouthpiece 29, thereby reducing the force. The lamp holder 30 (except for the lamp socket 40) has a weak action of restraining in the direction along the ring, and the force in the direction along the ring between the lamp socket 40 and the base 29 hardly acts.
