Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, in particular to a prism conversion structure of a stage lamp. Background Art

[0002] Stage lighting can effectively render the stage performance effect. Stage lights are commonly used stage lighting equipment. Stage lights can concentrate the light source on a focal point so that the light source is more concentrated or dispersed, forming a single beam or multiple beams, thereby creating a better stage lighting effect. During stage performances, stage lights are arranged around the stage, and the light beams are directed toward the stage in multiple directions, thereby creating a stage lighting effect.

[0003] Among them, the use of prisms in stage lighting systems is already very common. After passing through the prism, the light beam can produce colorful light spots and create a magical three-dimensional effect in the air. Therefore, prisms are deeply loved by stage lighting designers and have gradually become an indispensable element in stage lighting.

[0004] Currently, stage lighting fixtures are usually equipped with only one or two prisms, which are controlled separately by motors. They can produce a light spot by controlling a single prism to cut into the light path, or they can control two prisms to cut into the light path at the same time to achieve a superimposed effect. However, even so, the transformation effect that can be achieved by only one or two prisms is still quite limited. In actual stage applications, it has become increasingly difficult to meet the current stage lighting transformation needs. Utility Model Content

As the prism conversion disk 21 rotates, the light port 211 and the plurality of prism bodies 212 can be rotated in or out relative to the optical path area 11 in sequence.

[0024] It can be understood that the method of using the prism conversion structure of a stage light of the utility model is as follows: the prism conversion structure of the stage light can control any prism body 212 of a prism conversion module 20 to cut into the light path area 11, and the other prism conversion unit cuts into the light path area 11 with the light opening 211, so as to realize a single prism cutting into the light path area 11; or control any prism body 212 of two prism conversion modules 20 to cut into the light path area 11 at the same time, so as to realize a double prism cutting into the light path area 11, and the effect is superimposed. And, after any prism body 212 cuts into the light path area 11, the motor shaft of the prism self-rotating motor 22 rotates, and the gear ring transmission mechanism 30 drives the prism body 212 to rotate on the prism conversion disk 21, so as to realize the rotation function of the prism body 212 to enrich the lighting effect.
