Abstract
The invention discloses a lamp vibration damper, which comprises a vibration damper shell, an output shaft arranged in the vibration damper shell, an elastic component sheathed on the output shaft and contained in the vibration damper shell, cushion pads arranged on both ends of the vibration damper shell, and a pressing plate, wherein the pressing plate is next to one of the cushion pads, is arranged on the end part of the vibration damper shell, and is used for fixing and restricting the elastic component and the cushion pads. The lamp vibration damper can effectively isolate a ceiling lamp from vibration outside, and thus, the ceiling lamp can be better protected effectively. Due to the adoption of the elastic component for buffering vertical vibration or impact, the vibration damping mode by integrating the elastic component and the cushion pads has the advantages of low natural frequency, good vibration resistance and effective isolation from vertical and lateral vibration and impact; and the lamp can be protected effectively in all directions so as to guarantee the service performance of the lamp to be more stable.
