摘要：<P>PROBLEM TO BE SOLVED: To provide a resonance prevention device 1 for controlling a suspended luminaire 7 to prevent it from resonating when an earthquake occurs, thereby to prevent accidents wherein the suspended luminaire 7 largely vibrates and a luminaire body 7a is damaged by colliding with a ceiling surface 8 or the like, or a power cord 7c is cut and dropped, and to enhance safety of persons living below the suspended luminaire 7. <P>SOLUTION: A base plate 2 is attached to the ceiling surface 8, and a vibration stopping plate 3 is suspended from the base plate 2 by using three slinging materials 5. A pipe 6 having a length greater than half of a distance C between the base plate 2 and the vibration stopping plate 3 is erected and mounted on a center hole 3a of the vibration stopping plate 3, a wire cord 7c is made to pass through the center hole 3a of the vibration stopping plate 3 and the inside of the pipe 6, and the suspended luminaire 7 is attached to the ceiling surface 8. <P>COPYRIGHT: (C)2008,JPO&INPIT
