PURPOSE:To provide easy adjustability of the illuminating direction of an illumination device such as a desk lamp and floor light by furnishing motor driving means to all movable components or part thereof for changing the illuminating direction, and changing the illuminating direction with an operational switching means. CONSTITUTION:Operational signals for rotations in the regular or reverse direction as emitted from switches 4a, 4b, 4c are fed to driver circuits 6a, 6b, 6c, and electric power is supplied to respective motors 7a, 7b, 7c in conformity to these operational signals. The power supply for these motors shall be shared with power supply for illumination. Thus the switches 4a, 4b, 4c are turned on and off, and the illuminating condition is varied by a fluorescent lamp part 1 only through switching operation, wherein the risk is of touching the hot light source by mistake is also eliminated. Movable parts 2a, 2b, 2c are connected with the motors 7a, 7b, 7c through slip rings, and it is also made practicable to operate by hand according to necessity. |
