[0025] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] The present application relates to a stage lighting fixture, which comprises a light beam cutting device, and the light beam cutting device cuts a light beam and obtains a cutting pattern.

[0027] The other structures and operations of the stage lighting fixture have been recorded in the relevant technology for ordinary technicians in this field, and will not be described in detail here. The structure of the beam cutting device will be introduced below.

[0028] The present application relates to a beam cutting device, which includes a cutting support plate 1000, an aperture assembly 2000, a beam cutting assembly 3000 and a cutting imaging hole support plate 4000, wherein the aperture assembly 2000 is arranged on the surface of the cutting support plate 1000, the beam cutting assembly 3000 is arranged on the surface of the aperture assembly 2000, the beam cutting assembly 3000 is located between the aperture assembly 2000 and the cutting imaging hole support plate 4000, the aperture assembly 2000, the beam cutting assembly 3000 and the cutting imaging hole support plate 4000 are all connected to the cutting support plate 1000, and the cutting imaging hole support plate 4000 and the cutting support plate 1000 define an activity space for the beam cutting assembly 3000, thereby improving the stability of the activity of the beam cutting assembly 3000 and avoiding shaking. It can be understood that the cutting support plate 1000 is provided with a light-through hole, and the cutting imaging hole support plate 4000 is provided with an imaging hole 4100, and the imaging hole 4100 is used for beam pattern imaging.

[0029] Further, the beam cutting assembly 3000 includes a two-layer cutting blade assembly 3100, the cutting blade assembly 3100 includes a cutting blade 3101, the cutting blade 3101 is provided with a positioning hole 3103, and one side surface of the cutting blade 3101 is a light receiving surface. There are two cutting blades 3101 in the cutting blade assembly 3100, and the two cutting blades 3101 are symmetrically arranged. The cutting blade 3101 has a light cutting edge, and the light cutting edge is located on one side of the cutting blade 3101. The adjacent sides of the two cutting blades 3101 in the cutting blade assembly 3100 respectively have a light cutting edge.

[0030] The cutting blades of the beam cutting device in the related art are designed in a four-layer stacking manner. The light incident distance of the light incident surface of each layer of the cutting blade is large, resulting in low imaging clarity when cutting graphics, which is difficult to meet the effect requirements of the stage scene.

[0031] In the beam cutting assembly 3000 designed in the present application, the cutting blades 3101 are stacked in two layers in an interlaced manner, which reduces the light incident distance of the light incident surface of each layer of the cutting blades 3101 and improves the clarity of the cutting pattern. Specifically, the cutting edges of the two layers of cutting blade assemblies 3100 are arranged in an interlaced manner, wherein the cutting edges of one layer of the cutting blade assemblies 3100 extend longitudinally, and the cutting edges of the other layer of the cutting blade assemblies 3100 extend transversely.

[0032] The cutting edge of the cutting blade 3101 is provided with an inclined surface 3102, and one end of the inclined surface 3102 gradually extending outward along the inclined direction on the cutting edge is the distal end, and the other end is the proximal end. The distal end of the inclined surface 3102 is far away from the center of the cutting blade 3101, and the proximal end is closer to the center of the cutting blade 3101 than the distal end. Furthermore, the inclined surfaces 3102 of the two-layer cutting blade assembly 3100 are back-to-back and close to each other, thereby reducing the light-incoming distance of the light-incoming surface in each layer of the cutting blade assembly 3100, and the distance between the light-receiving surfaces of the cutting blades 3101 in the two-layer cutting blade assembly 3100 does not exceed 0.5mm, so as to ensure that the distance and light-receiving time of the light-receiving surfaces of the two-layer cutting blade assembly 3100 are close, thereby improving the clarity of the cutting pattern.

[0033] It should be noted that the inclined surfaces of the two cutting blades in the same layer of cutting blade assembly are close to each other to form a "V" shape, and the "V" shapes formed in the two layers of cutting blade assemblies face in opposite directions. Among them, the inclined surface of the cutting blade in the cutting blade assembly close to the light source forms a "V" shape with the opening facing the light source, and the inclined surface of the cutting blade assembly far from the light source forms a "V" shape with the opening facing away from the light source.

[0034] As an embodiment, the beam cutting assembly 3000 includes an elastic support member 3200, which is made of elastic material. The elastic support members 3200 are respectively arranged on both side surfaces of the beam cutting assembly 3000. The elastic support members 3200 apply elastic force to the cutting blade assembly 3100 to improve the structural stability of the cutting blade assembly 3100 and reduce the shaking of the cutting blade 3101.

[0035] Specifically, on the side of the beam cutting assembly 3000 close to the aperture assembly 2000, an elastic support member 3200 is arranged between the cutting blade assembly 3100 and the aperture assembly 2000, and on the side of the beam cutting assembly 3000 close to the cutting imaging hole support plate 4000, an elastic support member 3200 is arranged between the cutting blade assembly 3100 and the cutting imaging hole support plate 4000.

[0036] Furthermore, the elastic support member 3200 includes a spring sheet, which is provided with a light-through hole. The surface of the spring sheet is arched toward the cutting blade assembly 3100 so that the spring sheet generates elastic pressure on the cutting blade assembly 3100, thereby improving the stability of the cutting blade assembly 3100 and reducing shaking and avoiding problems such as displacement.

[0037] As an embodiment, the beam cutting assembly 3000 includes a spacer 3300, which is provided with a light-through hole. A spacer 3300 is provided between the two layers of cutting blade assemblies 3100, and a spacer 3300 is provided between the cutting blade assembly 3100 and the elastic support member 3200, so as to reduce the noise of the cutting blade 3101 during operation and ensure smooth operation to avoid jamming.

[0038] There are three spacers 3300, one of which is located between two layers of cutting blade assemblies 3100, and the other two spacers 3300 are respectively located between the cutting blade assembly 3100 and the elastic support member 3200. Between the cutting blade assembly 3100 and the elastic support member 3200, the arched surface of the elastic sheet of the elastic support member 3200 acts on the spacer 3300, so that the spacer 3300 keeps in contact with the cutting blade 3101.

[0039] Furthermore, the spacer 3300 is made of wear-resistant and high-temperature resistant material to prevent the spacer 3300 from deforming in a high-temperature environment.

[0040] The beam cutting device in the related art is designed with stainless steel sheets for each layer of cutting blades, but the cutting blades will rub against the stainless steel sheets to produce noise when in motion, and the stainless steel sheets are easily deformed by heat, which leads to the cutting blades jamming. Therefore, the present application uses wear-resistant and high-temperature resistant materials to make the spacer 3300, which is not easily deformed at high temperatures, avoids noise when the cutting blade 3101 moves, and reduces friction damage to the surface coating of the cutting blade 3101.

[0041] As an embodiment, the cutting blade assembly 3100 includes a rocker arm 3400 , one end of the rocker arm 3400 is connected to the cutting blade 3101 , and the other end of the rocker arm 3400 is used to connect to the rotating shaft of the motor, and the motor drives the cutting blade 3101 through the rocker arm 3400 .

[0042] Furthermore, the cutting blade 3101 is provided with a waist-shaped hole 3104 , and two waist-shaped holes 3104 are provided. The rocker arm 3400 is connected to the cutting blade 3101 via a connecting piece penetrating the waist-shaped hole 3104 .

[0043] In some examples, a rocker arm limiting column 1101 is respectively provided on the cutting support plate 1000 corresponding to each rocker arm 3400 , and the side of the rocker arm limiting column 1101 is used to abut the side of the rocker arm 3400 to limit the amplitude of the rocking of the rocker arm 3400 and improve the rocking stability of the rocker arm 3400 .

[0044] It should be noted that the motor drives the cutting blade 3101 in a single-arm rocker mode, which improves transmission efficiency and avoids problems such as cutting jamming, shaking, and displacement. The beam cutting device in the related art drives the cutting blade in a double-section rocker or synchronous belt transmission mode, which easily causes the cutting blade to move and shake, affecting the accuracy and stability of the cutting image.

[0045] As an embodiment, a plurality of first support columns for mounting the elastic support member 3200, the spacer 3300 and the cutting imaging hole support plate 4000 are provided on the cutting support plate 1000, and the elastic support member 3200, the spacer 3300 and the cutting imaging hole support plate 4000 are fixedly mounted on the first support columns by screws. Near the outer edge of the cutting support plate 1000, the first support columns are evenly spaced along the circumference.

[0046] It should be noted that the fixed connection between the cutting imaging hole support plate 4000 and the cutting support plate 1000 can limit the gap and operating space of the cutting blade 3101 to ensure that the cutting blade 3101 can operate within the limited space, thereby achieving clarity and consistency of the cutting pattern.

[0047] The cutting support plate 1000 is provided with a plurality of second support columns for supporting the aperture assembly 2000, and the aperture assembly 2000 is fixedly mounted on the second support columns by screws. On the cutting support plate 1000, the light hole is located at the center of the cutting support plate 1000, and the second support columns are evenly spaced along the circumference near the edge of the light hole.

[0048] As an embodiment, the aperture assembly 2000 includes an aperture and an aperture fixing plate. The inner hole of the aperture is coaxially arranged with the light hole of the cutting support plate 1000. The aperture is used to adjust the light beam, and the aperture fixing plate is used to fix the aperture and provide support for the installation of the cutting blade 3101.
