Description

technical field [0001] The invention relates to the technical field of lighting and photography, in particular to a laser lamp rotation device with high stability. Background technique [0002] At present, laser lights are widely used in outdoor projects such as buildings, parks, and squares due to their high brightness and good directivity. The beams emitted by laser lights generally output more lines or graphics through vibrating mirrors, prisms, and gratings. The angle will be limited by the optical properties. Therefore, in laser light engineering, it is usually necessary to use the rotation function to achieve large-angle coverage. The existing laser light rotation methods mainly include the following methods: 1) Assume that the laser light is placed on the monitoring platform. In this way, the strength of the structure is not enough, it is easy to crack and cause safety hazards, the load-bearing capacity is insufficient, and the heavy weight cannot be rotated. Disadv...

The existing laser light rotation methods mainly include the following methods: 1) Assume that the laser light is placed on the monitoring platform. In this way, the strength of the structure is not enough, it is easy to crack and cause safety hazards, the load-bearing capacity is insufficient, and the heavy weight cannot be rotated. Disadvantages such as laser lamp rotation; 2) Rotate the laser beam by refraction. This way, the scanning laser beam is emitted upward by installing a 45-degree reflector at the position of the rotating head, and the beam is refracted through the 45-degree reflector, so that The rotating head does not need to bear the weight of the laser light, but there are disadvantages such as the laser beam is easy to deviate from the optical path, causing hidden dangers or failures, and when the rotating head rotates, the beam will affect the direction of image output due to different refraction angles; 3) Install the laser on the At the bottom of the machine, the scanning galvanometer is installed in the upper small rotating head, and the lower beam is injected into the upper scanning galvanometer

Although this method ensures that the output graphics at any angle are consistent, there are disadvantages that the laser beam is easy to deviate from the optical path, causing safety hazards, and increasing maintenance costs. Due to the high energy of the laser beam, it often occurs that the laser beam deviates from the optical path and causes internal ignition. Devices and dust conditions require frequent maintenance and adjustments
