Description

Technical Field

[0001] This utility model belongs to the field of stage lighting technology, specifically relating to a combination pattern plate for stage lights. Background Technology

[0002] Stage lighting, also known as "stage illumination," is one of the means of stage art design. Modern stage performances have increasingly higher requirements for stage lighting and artistic design. To enhance the rendering effect and appeal of stage lighting, stage lighting fixtures often incorporate pattern disc components to enrich the lighting effects. Currently, the pattern discs used in stage lights are mainly divided into two types: fixed pattern discs and rotating pattern discs. Most spotlight stage lights are equipped with one or both of these types of pattern discs. Each type has its advantages, but also significant disadvantages.

[0003] A typical stage lighting pattern disc usually consists of multiple patterns formed on a single metal disc using etching or other processes, arranged symmetrically around its circumference. A rotating mechanism is located at the center of the disc, rotating the entire disc around this central axis to switch between different patterns. For example, Chinese Patent CN204593254U discloses a pattern disc for lighting fixtures, comprising a fixed disc ring and a fixed disc center.

[0004] However, while these fixed-pattern discs have advantages such as good temperature resistance, simple structure, and a large number of patterns, their disadvantages are also prominent: on the one hand, their pattern effects are fixed and they do not have dynamic effects such as rotation when used independently; on the other hand, the patterns cannot be changed independently, and the entire metal disc must be replaced to change the pattern.

[0005] A rotating pattern disc for stage lights generally includes a mounting base, a drive gear pivotally connected to the base, and multiple driven gears pivotally connected to the mounting disc and distributed around the drive gear. These driven gears mesh with the drive gear, and each driven gear has a pattern mounting base. Each base can hold a pattern. Besides rotating to switch patterns like a fixed pattern, the rotating pattern disc can also achieve pattern rotation by driving the driven gears through the central drive gear, creating a dynamic effect of a rotating stage beam. For example, Chinese patent CN201180939Y discloses a simple assembly and disassembly rotating pattern disc, which also mentions that the pattern pieces are fixed inside the rotating gears.

[0006] Although the patterns projected by the rotating pattern disc of the stage light have a dynamic and rotating effect, and the pattern pieces can be changed independently, it also has the following drawbacks: First, the pattern disc structure is relatively complex and occupies a relatively large space in the light body; second, the number of patterns on the pattern disc is small, which to some extent limits the diversity of stage lighting effects. Summary of the Invention

[0007] In response to the problems in related technologies, this utility model proposes a combined pattern plate for stage lights to overcome the aforementioned technical problems in existing related technologies. This utility model sets the fixed base in the gap, which realizes the increase of multiple patterns without increasing the overall space of the plate, effectively improving the space utilization rate.

The fixed pattern pieces 3 are detachably mounted on the fixed base 5, and the rotating pattern pieces 4 are detachably mounted on the gear seats 6.

[0052] Compared to the rotating pattern discs in existing stage lights, this embodiment achieves an increase in the number of patterns without increasing the overall space of the disc 1 by setting a gap 13 between adjacent gear seats 6 and placing the fixed base 5 within the gap 13.

[0071] Specifically, the number of the first patterned through-hole 11 is greater than the number of the second patterned through-hole 121;

[0072] like Figure 5 As shown, the fixed pattern sheet 3 includes a white light through hole sheet 10, and in this embodiment, multiple white light through hole sheets 10 with different inner diameters are provided.

[0073] Specifically, the disk 1 is circular or polygonal, and the fixed pattern piece 3 and the rotating pattern piece 4 are spaced apart along the circumferential direction or edge direction of the disk 1.
