Description

Technical Field

[0001] The invention belongs to the technical field of stage lamps, and in particular relates to a light path cutter. Background Art

[0002] Traditional stage light path cutters use eight motors to control four sets of cutting blades to move forward, backward, left and right to coordinate with each other to achieve the shape change of the middle light hole, so that the projected light can change into different shapes.

[0008] Furthermore, the cutting assembly includes two cutting blades arranged in parallel, and both ends of each cutting blade are respectively fixed on the linkage belt, so that the linkage belt drives both ends of each cutting blade to move in opposite directions, and the two cutting blades move synchronously.

By adding a second adjustment component, the second dimension of the cutting blade can be adjusted, enriching the light spot effect formed after the cutter is light-transmitting.

[0012] Furthermore, a second light-transmitting hole is opened in the middle of the fixing plate, and the second light-transmitting hole is an elliptical hole.

[0028] The main plate 100 is circular, with a first light-transmitting hole 101 in the middle, which is a circular hole. Two second adjustment components 300 are vertically arranged on the main plate 100, and each second adjustment component 300 includes a fixed plate 301 and a second transmission motor 302. The second transmission motor 302 is fixed on the main plate 100, and the second transmission motor 302 is connected to the fixed plate 301 through a screw drive. A second light-transmitting hole 303 is opened in the middle of the fixed plate 301, and the second light-transmitting hole 303 is an elliptical hole. The first adjustment component 200 is fixed on the fixed plate 301 of each second adjustment component 300.

[0029] In this embodiment, each first adjustment component 200 includes a first transmission motor 201, a cutting component 202 and a linkage belt 203. The first transmission motor 201 is fixed to one end of the fixed plate 301 away from the second transmission motor 302, and the linkage belt 203 is sleeved on the guide roller 204. The cutting component 202 is arranged above the fixed plate 301 and fixed on the linkage belt 203, and is connected to the second transmission motor 302 through the linkage belt 203. Specifically, the cutting component 202 includes two parallel cutting blades, and each of the two ends of the cutting blade is respectively fixed on the linkage belt 203, so that the linkage belt 203 drives the two ends of each cutting blade to move in opposite directions, and the two cutting blades move synchronously. The linkage belts 203 of the two groups of cutting components 202 are arranged perpendicular to each other, and the four cutting blades are enclosed to form a cutting light hole. By pulling the two groups of first adjustment components 200, a variety of light holes can be formed, and the light hole effect is adjusted in the first dimension. The fixing plate 301 is moved by the second transmission motor 302 to adjust the relative distance between the cutting component 202 in the first adjustment component 200 and the first light-transmitting hole 101, thereby adjusting and enriching the light hole effect from a second dimension.
