Description

Technical Field

[0001] The utility model relates to the technical field of stage lights, and more particularly to an optical effect sheet clamping structure, a driving module and a stage light having the same. Background Art

[0002] With the advancement of science and technology, current stage lighting technology has become increasingly mature, and the functions of stage lights have become increasingly sophisticated. Among them, the lamp head of a stage light generally houses a light source that generates a light path. To display a variety of lighting effects, different effect panels are primarily used to intercept the light beam and change the shape or color of the light spot. Stage lights are typically equipped with a variety of effect panels with different functions, such as atomizers, prisms, gobos, and color filters. To display different lighting effects, a driver module drives different effect panels into or out of the light path. However, current effect panels are primarily secured to the effect tray by plugging or gluing them together, with a transmission mechanism then selectively driving the different effect panels into or out of the light path. These fixed panels are difficult to remove and install, making replacement of individual effect panels a labor-intensive and time-consuming process. Furthermore, violent removal can easily damage the effect panel and its accessories, potentially affecting the functionality of other effect panels and hindering market adoption.

[0003] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide an optical effect sheet clamping structure for solving the problem that the existing optical effect sheet is difficult to disassemble or install, thereby achieving the effect of quickly disassembling and installing the optical effect sheet.

[0004] The utility model also discloses a driving module provided with the optical effect sheet clamping structure and a stage light provided with the driving module.

[0005] Based on this, the technical solution adopted by the utility model is:

[0006] An optical effect sheet clamping structure includes an elastic clamping portion and a fixed portion connected to each other. The elastic clamping portion is used to install the effect sheet, and the elastic clamping portion is an arc-shaped structure with an opening. The elastic clamping portion clamps the effect sheet within the arc-shaped structure through an interference fit with the effect sheet; the fixed portion is used to connect to an external drive motor, thereby driving the elastic clamping portion and the effect sheet to swing, thereby cutting the effect sheet into or out of the light path.

[0007] In this technical solution, the elastic clamping portion is an arc-shaped structure with an opening. Therefore, the effect sheet can be quickly clamped into the elastic clamping portion by holding it through the opening. The elasticity of the elastic clamping portion clamps the effect sheet tightly, preventing it from loosening. The elastic clamping portion is elastic. Therefore, when it is necessary to remove the effect sheet from the elastic clamping portion, the elasticity of the elastic support portion can be used to forcefully pull the effect sheet out of the opening of the elastic clamping portion, achieving rapid installation and removal of the effect sheet.

[0008] According to the optical effect sheet clamping structure of the present invention, the arc length of the elastic clamping portion is greater than half the circumference of the effect sheet.

[0009] According to the optical effect sheet clamping structure described in the utility model, the elastic clamping portion matches the outer periphery of the effect sheet, and its inner side surface abuts against the effect sheet, and the upper edge and lower edge of the inner side surface are respectively provided with an upper convex edge and a lower convex edge protruding toward the center of the effect sheet, and the upper convex edge and the lower convex edge are used to limit the effect sheet in the upper and lower directions.

[0010] According to the optical effect sheet clamping structure described in the present invention, the left and right ends of the upper convex edge and / or lower convex edge are designed as inclined surfaces, so that the width of the upper convex edge / lower convex edge gradually shortens from the inner side toward the center of the effect sheet.

[0011] According to the optical effect sheet clamping structure of the utility model, the upper convex edge and the lower convex edge are staggered with each other along the thickness direction of the inner side surface of the elastic clamping portion.

[0012] According to the optical effect sheet clamping structure described in the present invention, the inner side surface of the elastic clamping portion is provided with at least one group of upper convex edges and two groups of lower convex edges; or, the inner side surface of the elastic clamping portion is provided with at least two groups of upper convex edges and one group of lower convex edges.

[0014] According to the optical effect sheet clamping structure of the present invention, the elastic clamping portion and the fixing portion are integrally formed.

[0015] A driving module includes at least one of the above-mentioned clamping structures and a driving member. The fixing part of the clamping mechanism is connected to the driving member through a flange. The driving member drives the clamping structure to rotate by rotating, thereby causing the effect piece on the clamping structure to cut into or out of the light path.

[0016] A stage light comprises a lamp head, a support arm and a chassis, wherein the lamp head is rotatably connected to the support arm, the support arm is rotatably connected to the chassis, and further comprises the above-mentioned drive module, which is arranged in the lamp head.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

The utility model configures the elastic clamping portion as an arc-shaped structure with an opening, so that the effect sheet can be quickly inserted into the elastic clamping portion or quickly removed from the elastic clamping portion through the opening. The technical solution also limits the arc length of the elastic clamping portion to be at least half the circumference of the effect sheet to better clamp the effect sheet. To achieve a better fixing and limiting effect on the effect sheet in both the upper and lower directions, the technical solution also provides a ridge on the inner side edge of the elastic clamping portion. At the same time, by improving the ridge, it is possible to achieve the effect sheet being easily inserted into the elastic clamping portion while effectively preventing the ridge from affecting light output. Therefore, compared with the prior art, the utility model has a simple structure, is easy to assemble and disassemble, and is conducive to light output. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The drawings in this utility model are for illustrative purposes only and are not to be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the products. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment discloses an optical effect sheet clamping structure, comprising an interconnected elastic clamping portion 110 and a fixing portion 120, wherein the elastic clamping portion 110 and the fixing portion 120 are integrally formed. The elastic clamping portion 110 is used to mount the effect sheet 200, and the fixing portion 120 is used to connect to an external drive motor, thereby driving the elastic clamping portion 110 and the effect sheet 200 to swing, thereby cutting the effect sheet 200 into or out of the light path. To facilitate the installation of the effect sheet 200, the elastic clamping portion 110 is an arc-shaped structure with an opening, and the position of the opening can serve as the entrance and exit of the effect sheet 200, so as to facilitate the insertion or removal of the effect sheet 200. At the same time, the notch can also prevent the effect sheet 200 from being blocked by the elastic clamping portion 110 when it cuts into the light path. The arc-shaped structure is elastic, and the elastic clamping portion 110 clamps the effect sheet 200 within the arc-shaped structure through an interference fit with the effect sheet 200. Because the elastic clamping portion 110 is elastic, the effect sheet 200 can be clamped into the elastic clamping portion 110 by the elastic action when it is inserted into the elastic clamping portion 110, and the elastic action prevents the effect sheet 200 from being loosened. When the effect sheet 200 needs to be removed from the elastic clamping portion 110, a certain force is applied to release the clamping effect of the elastic clamping portion 110 on the effect sheet 200, and the effect sheet 200 can be removed, thereby achieving the purpose of quickly installing or removing the effect sheet 200.

[0030] The effect sheet 200 may be made of glass, metal, heat-resistant plastic or other materials.

[0031] Furthermore, in this embodiment, the effect sheet 200 can be at least one of an optical effect sheet such as an atomizing sheet, a prism, a pattern sheet, a color sheet, or a CTB sheet. The effect sheet 200 is circular, and correspondingly, the elastic clamping portion 110 is a circular ring structure with an opening. The diameter of the effect sheet 200 is slightly larger than the inner diameter of the elastic clamping portion 110, thereby achieving an interference fit. To better clamp the effect sheet 200, the arc length of the elastic clamping portion 110 is greater than half of the circumference of the effect sheet 200. That is, at least half of the circumference of the effect sheet 200 is in interference connection with the elastic clamping portion 110, and the effect sheet 200 is fixed in the radial direction by the elastic clamping portion 110 that exceeds half of the circumference.

[0032] Among them, the elastic clamping portion 110 matches the outer periphery of the effect piece 200, and its inner side surface abuts against the effect piece 200. The upper edge and lower edge of the inner side surface are respectively provided with an upper convex edge 111 and a lower convex edge 112 protruding toward the center of the effect piece 200. The upper convex edge 111 and the lower convex edge 112 are used to limit the effect piece 200 in the upper and lower directions.

[0033] Among them, a guide groove is formed between the upper convex edge 111 and the lower convex edge 112, which is concave toward the outer side of the elastic clamping portion 110, and the effect piece 200 can enter the elastic clamping portion 110 along the guide groove. That is, the effect piece 200 is limited and fixed in the upper and lower directions by the upper convex edge 111 and the lower convex edge 112.

[0034] The upper convex edge 111 and the lower convex edge 112 may be integrally provided on the inner side surface of the elastic clamping portion 110 , or may be provided on the inner side surface of the elastic clamping portion 110 in multiple sections.

[0035] Preferably, in this embodiment, the left and right ends of the upper convex edge 111 and / or the lower convex edge 112 are designed with bevels, so that the width of the upper convex edge 111 / lower convex edge 112 gradually decreases from the inner side toward the center of the effect sheet 200. The bevel design can help guide the effect sheet 200 to be inserted into the inner side of the elastic clamping portion 110, thereby improving the efficiency of installing the effect sheet 200.

[0036] Furthermore, in this embodiment, the upper convex edge 111 and the lower convex edge 112 are staggered along the thickness direction of the inner side surface of the elastic clamping portion 110. This arrangement ensures that the effect sheet 200 is fixed in both the upper and lower directions while also effectively preventing the upper convex edge 111 and the lower convex edge 112 from significantly affecting the light beam entering the effect sheet 200.

[0037] Furthermore, the inner side surface of the elastic clamping portion 110 is provided with at least one set of upper convex edges 111 and two sets of lower convex edges 112; or, the inner side surface of the elastic clamping portion 110 is provided with at least two sets of upper convex edges 111 and one set of lower convex edges 112. This ensures that the effect piece 200 is fixed in place at least in the middle and both ends of the elastic clamping portion 110, thereby preventing the effect piece 200 from loosening.

[0038] Furthermore, in this embodiment, the inner side surface of the elastic clamping portion 110 is provided with two groups of upper convex edges 111 and three groups of lower convex edges 112; or three groups of upper convex edges 111 and two groups of lower convex edges 112 can also be provided on the inner side surface of the elastic clamping portion 110. This configuration allows the upper convex edges 111 and lower convex edges 112 on both ends of the elastic clamping portion 110 to limit and fix the effect sheet 200 in the same direction, thereby improving the stability of the effect sheet 200. Preferably, when the inner side surface of the elastic clamping portion 110 is provided with two groups of upper convex edges 111 and three groups of lower convex edges 112, the width of the upper convex edges 111 can be set to be greater than the width of the lower convex edges 112; when the inner side surface of the elastic clamping portion 110 is provided with three groups of upper convex edges 111 and two groups of lower convex edges 112, the width of the lower convex edges 112 can be set to be greater than the width of the upper convex edges 111; so as to ensure that the upper convex edges 111 and the lower convex edges 112 can achieve the same stability.

[0039] This embodiment also discloses a driving module, including at least one of the above-mentioned clamping structures, and also includes a driving member 300. The fixing part 120 of the clamping mechanism is connected to the driving member 300 through a flange 310. The driving member 300 drives the clamping structure to rotate by rotating, thereby causing the effect sheet 200 on the clamping structure to cut into or out of the light path.

[0040] This embodiment further discloses a stage light, comprising a lamp head 400, a support arm 500, and a chassis 600. The lamp head 400 is rotatably connected to the support arm 500, which in turn is rotatably connected to the chassis 600. The stage light also comprises the aforementioned drive module, which is disposed within the lamp head 400. A light source for generating a light path is also mounted within the lamp head 400. The effect piece 200 is driven by the drive member 300 to enter or exit the light path. When the effect piece 200 enters the light path, the light beam is intercepted by the effect piece 200 to produce the corresponding effect.

[0041] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of the present invention shall be included within the scope of protection of the claims of the present invention.
