PROBLEM TO BE SOLVED: To adjust the installation position and height of a lamp as desired by stretching vertically or horizontally a pipe of an adjustable length and mounting the pipe with a movable support device. SOLUTION: A pipe portion to be fixed by being stretched against upper and lower ends or both side walls is made up of a small-diameter pipe 4 and a threaded pipe 6, each mounted with a rubber cap 1 and a spring 2, and a fastening screw 5 for length adjustment. The reason the small diameter pipe 4 and the threaded pipe 6 are mounted with the rubber caps 1 and the springs 2, is because play should be given to the length of the pipe portion when it is stretched. Holding brackets 3 are mounted on the pipe portion fixed in the vertical or horizontal direction. An A-support 7 with a B-support 8 is mounted on the holding brackets 3, a fluorescent lamp 9 is mounted on a tip thereof, and the holding brackets 3 are adjusted in height and fixed by fastening support fastening screws 10, 11.
