[0037] The stage lamp with the light path correction structure provided by the embodiment can correct the light path by slightly translating the light path correction plate 14 along the X-axis direction when the light path is abnormal. During the correction process, the zoom lens moving platform 30 will also slightly deviate and tilt when the second guide rod 52 moves with the light path correction plate 14, so as to adjust the zoom lens 3, because the second shaft sleeve 62 has the freedom in the X-axis direction with the zoom lens moving platform 30. Meanwhile, the zoom lens moving platform 40 will slightly deviate and tilt when the second guide rod 52 moves with the light path correction plate 14, so as to adjust the zoom lens 4, because the third shaft sleeve 63 has the freedom in the X-axis direction with the zoom lens moving platform 40. After the adjustment is completed, the nut 141 on the fixed threaded column 120 is tightened again, so that the light path correction plate 14 is locked and fixed again, thereby saving the adjustment of the light path.

[0038] Further, in the stage lamp, the atomizing sheet generally needs to maintain a relatively fixed positional relationship with the zoom lens 3. If the atomizing sheet and the zoom lens 3 cannot maintain parallelism, the uniformity and stability of the light atomizing effect will be affected. Therefore, the light path atomizing assembly 9 is arranged on the zoom lens moving platform 3, so that the atomizing sheet can be adjusted together with the zoom lens 3, and the atomizing sheet and the zoom lens 3 always maintain a relatively parallel and fixed positional relationship during the light path correction process, thereby avoiding the influence of the light path correction process on other light effects in the stage lamp.

[0039] The utility model provides a stage lamp with light path correction structure, provides simple, fast and effective light path correction means for stage lamp through a little transformation to the moving platform of zoom lens and zoom lens, can quickly correct the light path eccentric problem of stage lamp. Meanwhile, the utility model still greatly reduces the light path maintenance cost of stage lamp, prolongs the service life of stage lamp, wherein the light path correction structure has the advantages that the flexibility is high, and the adjustment is convenient, even if the staff without professional engineering experience can also independently complete the light path correction operation.

[0040] The above-mentioned embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent range. It should be pointed out that, for ordinary skilled person in the art, under the premise of not departing from the utility model concept, a plurality of deformation and improvement can be made, which all belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be the attached right claim.
