Description

Technical Field

[0001] The present invention relates to the technical field of stage light illumination, and particularly to a color wheel device for a stage light. Background Art

[0002] In a Chinese invention patent (publication number CN101430070B), a color wheel and its disclosed accessories are made public. Figure 1 As shown, the specific technical solution is as follows: A color wheel mainly includes a color filter, a support plate, and a radially protruding spring. The front end of the color filter is located between the radially protruding spring and the support plate, so that the front end of the color filter is pressed tightly by the elastic force of the radially protruding spring.

[0003] The defect faced by this technical solution is that only the front end of the color filter is pressed tightly, but the rear end is not pressed tightly or fixed by other fixing structures, which easily causes the color filter to come out from the rear end. Therefore, the stability of the color filter is poor, and the effective output of the stage light effect cannot be guaranteed. Summary of the Invention

[0004] The present invention provides a color wheel device for a stage light to solve one of the above technical problems, in which both the front and rear ends of the color filter can be pressed tightly, so that it has good stability and is not easy to come off.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A color wheel device for a stage light includes a color disk, an elastic pressing plate, and one or more color filters. A plurality of radial protrusions are circumferentially distributed on the color disk, and adjacent radial protrusions are spaced apart to form light passing holes for light to pass through. The color filters are selectively arranged in the light passing holes. A supporting protrusion for abutting against the color filter is arranged on the inner wall of the light passing hole corresponding to the color filter. The elastic pressing plate is fixed on the color disk, and the elastic pressing plate is provided with a first elastic pressing portion corresponding to each color filter. A tight-fitting groove for inserting the front end of the color filter is formed between the first elastic pressing portion and the supporting protrusion. The color disk is provided with a pressing mechanism for pressing the end of the color filter and fixing it on the color disk.

[0007] As a preferred embodiment, it is further defined that the pressing mechanism includes an elastic pressing member movably arranged on the color disk. The elastic pressing member forms an unlocking position and a pressing position during the moving process. When the elastic pressing member rotates to the unlocking position, the color filter can be withdrawn from the tight-fitting groove. When the elastic pressing member rotates to the pressing position, the elastic pressing member presses the end of the color filter against the supporting protrusion.

[0008] As a preferred embodiment, it is further defined that the elastic pressing member includes a main body portion, a second elastic pressing portion provided at one end of the main body portion, and a flanging portion formed by folding the side end of the second elastic pressing portion. The supporting protrusion is provided with an avoidance groove. When pressed, the second elastic pressing portion abuts against the top of the end of the color filter, and the flanging portion abuts against the avoidance groove to prevent the color filter from being disengaged from the tight-fitting groove.

[0009] As a preferred embodiment, it is further defined that the radial protrusion is rotatably connected to the other end of the main body portion by a riveting member.

[0010] As a preferred embodiment, it is further defined that the main body portion is a bent section bent downward.

[0011] As a preferred embodiment, it is further defined that the elastic pressing plate further includes a fixed pressing portion beside the first elastic pressing portion, and the tight-fitting groove is further formed by the fixed pressing portion and the supporting protrusion.

[0012] As a preferred embodiment, it is further defined that the distance L1 between the first elastic pressing portion and the supporting protrusion is less than the distance L2 between the fixed pressing portion and the supporting protrusion.

[0013] After adopting the above technical solution, the present invention has at least the following beneficial effects:

[0014] 1. While the front end of the color filter is pressed by the first elastic pressing portion, the end of the color filter is also pressed by the elastic pressing member of the pressing mechanism, which can effectively enhance the stability of the color filter, prevent the color filter from tilting or disengaging from the end, and thus ensure the stable output of the stage lighting effect.

[0015] 2. The elastic pressing member includes a main body portion, a second elastic pressing portion provided at one end of the main body portion, and a flanging portion formed by folding the side end of the second elastic pressing portion. The supporting protrusion is provided with an avoidance groove. When pressed, the second elastic pressing portion abuts against the top of the end of the color filter, and the flanging portion abuts against the avoidance groove to prevent the color filter from being disengaged from the tight-fitting groove. The second elastic pressing portion can limit the axial movement of the color filter, while the flanging portion can limit the radial movement of the color filter, thereby ensuring the stability of the color filter in all directions.

[0019] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] As shown in the attached Figure 1 to the attached Figure 3 figures, a color wheel device of a stage light includes a color disk 1, an elastic pressing plate 2, and one or more color filters 3. The plurality of color filters 3 are color filter sheets of different colors; a plurality of radial protrusions 11 are circumferentially distributed on the color disk 1, and adjacent radial protrusions 11 are spaced apart from each other to form a light passing hole 10 for light to pass through. The color filter 3 is selectively arranged in the light passing hole 10. Among them, one light passing hole 10 is left without a color filter 3 to allow the original color light to pass through this light passing hole 10, and different color filters 3 can be arranged in the remaining light passing holes 10; on the inner wall of the light passing hole 10 corresponding to the color filter 3, there is a supporting protrusion 12 for abutting against the color filter 3. Specifically, the supporting protrusion 12 is arranged around the inner wall of the light passing hole 10, so that the front, rear, left, and right ends of the color filter 3 are all abutted against the supporting protrusion 12; the elastic pressing plate 2 is fixed on the color disk 1, and the elastic pressing plate 2 is provided with a first elastic pressing part 21 corresponding to each color filter 3. A tight-fitting groove 100 is formed between the first elastic pressing part 21 and the supporting protrusion 12 for the front end 31 of the color filter 3 to be inserted. The first elastic pressing part 21 has a certain elasticity so that the front end of the color filter 3 is kept pressed in the tight-fitting groove 100 without loosening; further, the color disk 1 is provided with a pressing mechanism for pressing the end 32 of the color filter 3 and fixing it on the color disk 1.

[0021] In this embodiment, the pressing mechanism includes an elastic pressing member 4 movably arranged on the color disk 1. The elastic pressing member 4 forms an unlocking position and a pressing position during the moving process. When the elastic pressing member 4 rotates to the unlocking position, the color filter 3 can be withdrawn from the tight-fitting groove 100. When the elastic pressing member 4 rotates to the pressing position, the elastic pressing member 4 presses the end 32 of the color filter 3 against the supporting protrusion 12.

[0022] Specifically, while the front end of the color filter 3 is pressed by the first elastic pressing part 21, the end of the color filter 3 is also pressed by the elastic pressing member 4 of the pressing mechanism. This can effectively enhance the stability of the color filter 3, prevent the color filter 3 from tilting or coming out from the end, thereby ensuring the stable output of the stage lighting effect.

[0023] Further, the elastic pressing member 4 includes a main body portion 41, a second elastic pressing portion 42 provided at one end of the main body portion 41, and a flanging portion 43 formed by folding the side end of the second elastic pressing portion 42. The supporting protrusion 12 is provided with an avoidance groove 121. When pressed tightly, the second elastic pressing portion 42 abuts against the top of the end 32 of the color filter 3, and the flanging portion 43 abuts against the avoidance groove 121 to limit the color filter 3 from being disengaged from the tight-fitting groove 100. Similarly, the second elastic pressing portion 42 also has a certain degree of elasticity, so that the end 32 of the color filter 3 is kept pressed tightly under the elastic action of the second elastic pressing portion 42. To further elaborate, the second elastic pressing portion 42 can limit the axial movement of the color filter 3, while the flanging portion 43 can limit the radial movement of the color filter 3, thereby ensuring the stability of the color filter 3 in all directions.

[0024] In this embodiment, the radial protrusion 11 is rotatably connected to the other end of the main body portion 41 through a riveting member 5, and the riveting member 5 is a rivet.

[0025] In this embodiment, the main body portion 41 is a bent section bent downward, which is beneficial to enhancing the rigidity of the elastic pressing member and also enhancing the pressing degree of the elastic pressing member 4 on the color filter 3.

[0026] In this embodiment, the elastic pressing plate 2 further includes a fixed pressing portion 22 located beside the first elastic pressing portion 21. The tight-fitting groove 100 is further formed by the fixed pressing portion 22 and the supporting protrusion 12. The fixed pressing portion 22 does not have an elastic force and is mainly used to limit the axial movement range of the color filter 3, so as to prevent the color filter 3 from being disengaged when the external force is greater than the elastic force of the first elastic pressing portion 21. Further, the distance L1 between the first elastic pressing portion 21 and the supporting protrusion 12 is less than the distance L2 between the fixed pressing portion 22 and the supporting protrusion 12, so that the color filter 3 has a certain buffer space in the axial direction, and the risk of damage to the color filter 3 caused by external impact can be reduced.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various equivalent changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalent scope.
