[0002] In the field of stage lighting art, creating unique and eye-catching lighting effects is essential to enhance the overall atmosphere of stage performances. Traditional stage lighting devices usually use prisms alone or rainbow discs alone; using rainbow discs alone can make the pattern appear multi-color splicing to present a colorful pattern effect, but generally speaking, the effect of using color discs alone is not good. The colors are difficult to separate, making the pattern look dirty, and the pattern will be a bit messy, and the colors appear very chaotic. Using prisms alone will result in a monotonous effect, and you can only see the superposition of patterns. If you need to inject color, you can only use the color chips on the color disc, and the color is also relatively single; so that the overall stage lighting effect is relatively monotonous.

[0034] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.
[0035] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.
[0036] Example:
[0037] See also Figure 1In one embodiment of the present application, a stage lighting device is provided, comprising:
[0038] A lens group, including a focusing lens 2 and a zoom lens 5;
[0039] The prism 3 is arranged between the focusing lens 2 and the zoom lens 5 of the lens group, and is used to disperse the incident light into light in multiple directions to form a pattern effect;
[0040] A color plate 4, arranged behind the prism 3 and in front of the zoom lens 5, for providing color to the light;
[0041] The light is sequentially projected toward the stage through the focusing lens 2, the prism 3, the color plate 4 and the zoom lens 5 to obtain light with different color pattern effects.
[0042] As one implementation manner, the stage lighting device is further provided with a light hole 1 .
[0043] By adjusting the size of its aperture, you can effectively control the amount of light entering the system. When a strong lighting effect is required, the aperture can be enlarged to allow more light to enter; when soft or precise lighting is required, the aperture can be narrowed to limit the amount of light entering.
[0044] As one implementation manner, the zoom lens 5 is used to adjust the focal length of the light, thereby changing the projection distance and projection range of the light.
[0045] As one of the embodiments, the focusing lens 2 is used to adjust the focus of the light, that is, to adjust the degree of convergence or divergence of the light. Specifically, the focusing lens 2 is usually composed of a group of lenses, and the lenses can be fixed or adjustable. By changing the relative position between the lenses, or changing the curvature of the lenses themselves, the focusing lens 2 can change the focal point of the light to flexibly control the focal position of the light.
[0046] Specifically, the zoom lens 5 can continuously or step by step change the effective focal length of the light through its internal lens combination and mechanical adjustment mechanism. The adjustment of the focal length directly affects the position where the light converges in space. When the focal length becomes longer, the light is focused more tightly, causing the light beam projected onto the target area (such as the stage) to become narrower and the viewing angle to be correspondingly reduced, thereby achieving magnified observation or projection of distant details and increasing the magnification of the light; on the contrary, when the focal length becomes shorter, the focal point of the light moves backward, the projected light beam becomes wider, and the viewing angle increases accordingly, which is suitable for covering a wider area or showing a wider scene. The user can flexibly adjust the coverage range and focusing accuracy of the light according to the performance requirements. The zoom lens 5 in the embodiment of the present application can create a variety of visual effects from close-up focus to wide-angle display, greatly enriching the expressiveness of stage lighting design.
[0047] As one implementation manner, the color plate 4 is a disc-shaped structure.
[0048] As one implementation method, the color plate 4 may have a plurality of color chips, which are of the same size and evenly distributed; for example, there are eight color chips on the color plate 4, see Figure 2 The structure of the color plate 4.
[0049] As one implementation manner, the colors of the multiple color chips are different.
[0050] Specifically, the color plate 4 in the embodiment of the present application can have multiple color chips, which can ensure that rich and varied color combinations can be produced when the color plate is rotated; the multiple color chips are of the same size and evenly distributed, ensuring that no matter which position the color plate is rotated to, the color transition can be kept natural and smooth, avoiding color jumps or missing; the colors of the multiple color chips on the color plate are different. For example, when there are eight color chips on the color plate 4, these color chips may include white, red, orange, yellow, green, blue, indigo, purple, etc., enriching the stage visual effects.
[0051] As one implementation method, the number of facets of the prism 3 is equal to the number of color sheets of the color plate 4. For example, if there are eight color sheets on the color plate 4, the prism 3 is an octagonal prism. Figure 3 prism structure.
[0052] As one implementation manner, the refractive index of the prism is between 1.5 and 1.9.
[0053] In addition, the larger the tilt angle of the prism, the more divergent the light is, and the farther the pattern effect is from the center. The smaller the tilt angle, the more concentrated the light is, and the more concentrated the pattern effect is. The thickness of the prism depends on the tilt angle of the prism.
[0054] Specifically, the light in the stage lighting device of the present application passes through the focusing lens 2 in sequence, and then passes through the prism 3 for splitting, and then passes through the corresponding color film on the color plate 4, so that the pattern effect of the prism 3 can appear in different colors, and the color of a single pattern is full and uniform, and finally is projected onto the stage through the zoom lens to form a pattern effect with different colors, please refer to Figure 4 .
[0055] In the present application, placing the prism and the multi-color disc between the focusing lens and the zoom lens can prevent the prism and the multi-color disc from being imaged directly through the light output lens.
[0056] See also Figure 5 In another embodiment, the present application provides a method for using a stage lighting device, comprising the following steps:
[0057] S1. Turn on the light source, and the light enters the stage lighting device.
[0058] Furthermore, when the start button of the light source is pressed, light will be emitted from the light source and enter the stage lighting device through the designed light hole. The light hole controls the size of the light entrance and also plays a role in initial focusing and guiding, ensuring that the light can propagate along the preset path.
[0059] S2. The light is adjusted to a focal position through a focusing lens along a preset path to obtain a focused first light.
[0060] S3. The first light is split by a prism to obtain first light in multiple directions to form a pattern effect.
[0061] After the focus is adjusted by the zoom lens, the light passes through the prism again; the prism has a special optical structure inside that can disperse the light into multiple directions.
[0062] The scattered light forms a specific pattern effect in the space, such as square, fan, circle or irregular shape, etc. The shape and size of the pattern can be changed by adjusting the angle or position of the prism.
[0063] S4. The first light rays in the multiple directions pass through the color sheets on the color plate to obtain pattern effects with different colors.
[0064] The scattered light will then pass through the color plate. There are multiple color chips distributed on the color plate, each with a different color. When the light passes through the color chip, it will be dyed with the corresponding color. Because the light is scattered, the light in each direction passes through a different color chip, thus forming a multi-color pattern effect, creating a colorful lighting effect.
[0065] S5. The light with pattern effects of different colors passes through a zoom lens again to adjust the focal length of the light with pattern effects of different colors.
