<p>PROBLEM TO BE SOLVED: To prevent loosening of a socket and a base even in long time use, and to improve earthquake resistance.SOLUTION: A base 6 is provided at an upper part of a cylindrical body 5 standing from a center of a lighting fixture body 1 which has radiation fins radially in the periphery. A support rod 12 is suspended from a ceiling surface, and a socket 13 is provided at a lower part of the support rod 12. A reinforcement metal fitting body 20 is mounted so as to cover the socket 13 and the upper part of the cylindrical body 5 from left and right. The reinforcement metal fitting body 20 is configured by a right half-split body 21 and a left half-split body 22. On the inner surface of both half-split bodies 21, 22, adhesive sheets 34, 36 and a pressure contact member 32 are disposed. By bringing the socket 13 and the upper part of the cylindrical body 5 into pressure contact with the adhesive sheets 34, 36 and the pressure contact member 32, the socket 13 and the lighting fixture body 1 side are firmly connected and fixed in an integral manner.</p> |
