The bearing bracket part 3 with the bearing 4 fixed to the upper end of the bottom plate part 2 is bent and formed. At the same time, the motor bracket part 5 on which the motor 6 is fixedly attached to the lower end is integrally bent. It was formed by In addition, 7 surrounds the outer periphery of a board on which a large number of LEDs 8, 8... are arranged in a vertical line, and It is a hood with a long rectangular projection opening 9, and a rotary hood protruding from the base of the hood 7. The upper end of the shaft 10 is rotatably installed in the bearing 4, and the lower end is connected to the shaft coupling 1. 1 to the drive shaft of the motor 6 to form a rotation unit 12. be.

[0008] A pair of sliding rings 13 and 14 are spaced apart from each other and are externally attached to the upper rotating shaft 10.
