Description

Technical Field

[0001] The utility model relates to the technical field of stage lighting equipment, and particularly relates to a light extinction device for a multi-aperture zoom LED stage light. Background Art

[0002] Due to many advantages such as high luminous efficiency, good combined rendering effect, energy conservation and environmental protection, and long service life, LED light sources are widely used in stage lighting fixtures. In recent years, a multi-light-source combined zoom LED stage light has emerged. Its light source module is integrated by multiple multi-in-one (including four colors of Red, Green, Blue, and White integrated into one) LED lamp beads. Each light source has an independent light guide system and light exit hole, and can realize functions such as beam zoom and beam rotation and deflection. The colorful lights are concentrated and emitted by the lamp head, which is very popular in the market.

[0003] However, such lighting fixtures still have some deficiencies. Among them, the biggest deficiency is that during the process of beam zoom projection, some lenses will reflect light on the surface of accessories in a certain stroke section, resulting in messy light mixed in the finally emitted light, which affects the stage lighting effect.

[0004] In the prior art, for the above-mentioned stray light problem, matte paint is usually sprayed on some easily reflective fittings. However, according to the final test results, the stray light cannot be completely eliminated, or most of the stray light cannot be eliminated, which cannot meet the standards of high-demand performance venues. There are also manufacturers who add light-blocking accessories to the optical path of stage lighting fixtures. However, such operations will occupy more space of the lighting fixtures, or cause an increase in the overall volume and weight of the lighting fixtures, which is not conducive to the development of stage lighting fixtures towards miniaturization and light weight.
