When the illuminating lamp 21 and the mounting rod 24 vibrate, the illuminating lamp 21 and the mounting rod 24 can rotate in the horizontal plane around the joint of the ball pair 25 and the mounting seat 23 through the ball pair 25, and when the illuminating lamp 21 and the mounting rod 24 rotate, the first spring 26 can be compressed or stretched, so that the kinetic energy of the illuminating lamp 21 and the mounting rod 24 is converted into the elastic potential energy of the first spring 26, the vibration of the illuminating lamp 21 and the mounting rod 24 is absorbed, and the influence caused by the vibration is reduced.

Based on the foregoing, in the present embodiment, the outdoor lamp is easily vibrated due to uneven road surface during transportation, and the vibration mainly occurs in the vertical direction, for this reason, in the present embodiment, the mounting base 23 is rotatably connected to the vertical plate 122 of the mounting base 1 through the rotating shaft 231, one end of the rotating shaft 231 is fixedly connected to the swing arm 2311, one end of the swing arm 2311 away from the rotating shaft 231 is fixedly connected to the counterweight 22, and the counterweight 22 can swing around the axis of the rotating shaft 231, when the rotating shaft 231 does not rotate, the swing arm 2311 extends in the vertical direction under the action of the counterweight 22, and when the illuminating lamp 21 vibrates in the vertical direction, the illuminating lamp 21, the mounting rod 24, the ball pair 25, the first spring 26 and the mounting base 23 can rotate in the vertical plane around the axis of the rotating shaft 231 through the rotating shaft 231, and at the same time, the counterweight 22 swings around the axis of the rotating shaft 231, so as to convert kinetic energy of the illuminating lamp 21, the mounting rod 24, the ball pair 25, the first spring 26 and the mounting base 23 into gravitational potential energy of the counterweight 22, and further absorb the influence of the illuminating lamp 21 and the mounting rod 24, the ball pair 25, the first spring 26 and the mounting base 23, thereby reducing the influence of the vibration.
