PURPOSE: To simplify operations of putting-on and taking-off, and to keep an equipping condition stable without enlarging the luminaire body, by rotationally supporting a plug receiving body connected with a single-base fluorescent lamp by a carrier, and by detachably holding the fluorescent lamp supported by the carrier, in the prescribed posture by an elastic retaining mechanism. CONSTITUTION: A plug receiving body A is connected with a single-base fluorescent lamp L, and a carrier B rotationally supporting the plug receiving body A is detachably supported by an elastic retaining mechanism C, in the prescribed posture. Elastic engaging pieces 6 provided to the carrier B are engaged with projections 10 arranged on the peripheral surface of a base 9 of the lamp L. Engaging parts 6a of the engaging pieces 6 are engaged with the projections 10, under the condition that the lamp L is in the prescribed posture of turning-on, thereby the rotation of the plug receiving body A is regulated. At the same time, the base 9 is pressed against the plug receiving body A to prevent slip off the lamp L, and the posture of the lamp L is kept stable. |
