Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a color wheel assembly and its stage light. Background Technology

[0002] The color wheel is a key component in stage lighting equipment, used to change the color of the emitted light by rotating it to switch between different color filters. Color wheel assemblies are typically driven by a motor, with color switching achieved by controlling the motor's speed or position. However, existing color wheel assemblies suffer from the following problem: during prolonged operation or high-speed switching, the color filters are prone to shifting due to color wheel inertia or external interference, thus affecting the accuracy of the color output. Summary of the Invention

[0003] To solve one of the above-mentioned technical problems, the present invention provides a color wheel assembly and a stage light using the color wheel assembly, which can achieve convenient disassembly and assembly and prevent the color filter from shifting.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A color wheel assembly includes a color wheel, a fixing member fixedly disposed on the color wheel, and a plurality of color filters circumferentially distributed on the color wheel. The fixing member is provided with a plurality of elastic sheets extending in its circumferential direction. The fixing member fixes and presses the color filters one by one onto the color wheel through the elastic sheets. A limiting mechanism is provided between the color wheel and the color filters to position the color filters after they are pressed together.

[0006] As a preferred embodiment, the limiting mechanism is further defined as follows: the limiting mechanism includes at least two protrusions on the color filter and at least two positioning holes on the color wheel, the protrusions and positioning holes being positioned correspondingly, and the protrusions of the color filter being held in the positioning holes of the color wheel under the pressure of the fixing member.

[0007] As a preferred embodiment, the color filter is further defined as follows: the color filter includes an insert block and a color sheet fixedly connected to the insert block; the lower end of the insert block is provided with a limiting protrusion; the color disc is provided with a limiting notch that engages with the limiting protrusion; after the limiting protrusion of the insert block is inserted into the limiting notch, the color filter is pressed by the corresponding elastic sheet.

[0008] In a preferred embodiment, the insert further includes a pressing part and a fixing part. The upper end of the pressing part is fixedly connected to the fixing part, and the fixing part extends beyond the rear end of the pressing part, so that the connection between the pressing part and the fixing part forms a stepped shape. The lower end of the pressing part is fixedly connected to a limiting protrusion, and the limiting protrusion also extends beyond the rear end of the pressing part, so that a slot for the color piece to be inserted is formed between the fixing part and the limiting protrusion.

[0009] As a preferred embodiment, the fixing part is further defined as having an opening communicating with the slot.

[0010] As a preferred embodiment, the insertion block is further defined as having a pressing groove, and the elastic sheet is adapted to be pressed into the pressing groove.

[0011] As a preferred embodiment, the insertion block is further defined as having notches located on both sides of the pressing groove.

[0012] As a preferred embodiment, it is further defined that the color wheel is provided with a plurality of first receiving portions extending radially therebetween, and a light-transmitting opening communicating with the limiting notch is formed between adjacent first receiving portions. When the elastic sheet and the color filter are pressed together, the left and right edges of the color filter abut against the first receiving portions, so that the color filter covers the light-transmitting opening.

[0013] As a preferred embodiment, it is further defined that a second receiving part extending along the circumference of the color wheel is connected between the outer ends of adjacent first receiving parts, and the rear edge of the color filter abuts against the second receiving part when the elastic sheet and the color filter are pressed together.

[0014] A stage light includes a light source and a color wheel assembly for optical coupling with the light source.

[0015] By adopting the above technical solution, the present invention has at least the following beneficial effects:

[0016] 1. A limiting mechanism is provided between the color wheel and the color filter to position the color filter after it is pressed together. This solution uses an elastic sheet to fix the color filter by pressing, which facilitates the installation and removal of the color filter. The limiting mechanism is used to prevent the color filter from shifting when rotating after the elastic sheet is pressed together, thereby ensuring accurate and effective output of light.

[0017] 2. The elastic sheet is used to limit the axial movement of the color filter, while the cooperation of the protrusion and the positioning hole not only limits the radial movement of the elastic sheet, but also limits the circumferential movement of the elastic sheet. By limiting the position of the color filter in all directions, the stability of the color filter is further enhanced.

[0018] 3. Both the limiting protrusion and the limiting notch are rectangular, which facilitates the quick and accurate assembly of the color filter. In addition, the cooperation between the two can play a guiding and limiting role. Attached Figure Description

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0025] As attached Figure 1 As shown, a color wheel assembly includes a color wheel 1, a fixing member 2 fixedly mounted on the color wheel 1, and several color filters 3 circumferentially distributed on the color wheel 1. The fixing member 2 is provided with several elastic sheets 21 extending in its circumferential direction. The fixing member 2 fixes and presses the color filters 3 one by one onto the color wheel 1 through the elastic sheets 21. A limiting mechanism is provided between the color wheel 1 and the color filters 3 to position them after they are pressed together. This solution uses the elastic sheets 21 to fix the color filters 3 by pressing them together, thereby facilitating the installation and removal of the color filters 3. The limiting mechanism is used to prevent the color filters 32 from shifting during rotation after being pressed together by the elastic sheets 21, thereby ensuring accurate and effective light output.

[0026] As attached Figure 2 and attached Figure 3As shown, the limiting mechanism includes at least two protrusions 30 on the color filter 3 and at least two positioning holes 11 on the color wheel 1. The protrusions 30 and positioning holes 11 are positioned opposite each other. Under the pressure of the fixing member 2, the protrusions 30 of the color filter 3 are held in place in the positioning holes 11 of the color wheel 1. Preferably, the protrusions 30 are cylindrical with a diameter of approximately 2 mm. Similarly, the diameter of the positioning hole 11 that mates with the protrusion 30 is also approximately 2 mm to ensure precise fit between the two. Specifically, there are two protrusions 30 and two positioning holes 11 to increase stability after positioning. The elastic sheet 21 is used to limit the axial movement of the color filter 3, while the cooperation between the protrusions 30 and the positioning holes 11 not only limits the radial movement of the elastic sheet 21 but also limits the circumferential movement of the elastic sheet 21. By limiting the color filter 3 in multiple dimensions, the stability of the color filter 3 is further enhanced.

[0027] As attached Figure 3 As shown, the color filter 3 includes an insert block 31 and a color sheet 32 ​​fixedly connected to the insert block 31. The lower end of the insert block 31 is provided with a limiting protrusion 313. The color disc 1 is provided with a limiting notch 12 that engages with the limiting protrusion 313. After the limiting protrusion 313 of the insert block 31 is inserted into the limiting notch 12, the color filter 3 is pressed by the corresponding elastic sheet 21. Both the limiting protrusion 313 and the limiting notch 12 are rectangular, which facilitates the quick and accurate assembly of the color filter 3. In addition, the cooperation between the two can play a guiding and limiting role. It can be understood that: 1. When inserted, the limiting notch 12 can guide the limiting protrusion 313 to slide precisely into the insertion; 2. After insertion, the limiting protrusion 313 and the limiting notch 12 are tightly fitted together, which can effectively prevent the color filter 3 from shifting in the circumferential direction.

[0028] As attached Figure 3 As shown, the insert block 31 further includes a pressing part 311 and a fixing part 312. The upper end of the pressing part 311 is fixedly connected to the fixing part 312, and the fixing part 312 extends beyond the rear end of the pressing part 311, so that the connection between the pressing part 311 and the fixing part 312 forms a stepped shape. The lower end of the pressing part 311 is fixedly connected to the limiting protrusion 313, and the limiting protrusion 313 also extends beyond the rear end of the pressing part 311, so that a slot 314 for the color piece 32 to be inserted is formed between the fixing part 312 and the limiting protrusion 313. The slot 314 can improve the assembly efficiency between the color piece 32 and the insert block 31. The color piece 32 is inserted into the slot 314 and then glued and fixed.

[0029] As attached Figure 4As shown, the fixing part 312 has an opening 315 communicating with the slot 314. The opening 315 is used for the injection of glue. Specifically, the color piece 32 is first inserted into the slot 314, and then glue is injected from the opening 315 to complete the bonding and fixing between the color piece 32 and the insert 31.

[0030] As attached Figure 4 As shown, the insert block 31 is provided with a pressing groove 316, and the elastic sheet 21 is adapted to be pressed into the pressing groove 316. The elastic sheet 21 is rectangular strip and the pressing groove 316 is rectangular, so that the elastic sheet 21 and the pressing groove 316 are fully fitted together to improve the tightness between the elastic sheet 21 and the pressing groove 316.

[0031] As attached Figure 4 As shown, the insert 31 is provided with notches 317 on both sides of the pressing groove 316. The two notches 317 at the cut of the insert 31 help to reduce the weight of the insert 31 and make the color wheel assembly lighter.

[0032] As attached Figure 1 and attached Figure 2 As shown, the color wheel 1 is provided with a plurality of first receiving portions 13 extending radially at intervals. A light-transmitting opening 14 communicating with the limiting notch 12 is formed between adjacent first receiving portions 13. When the elastic sheet 21 and the color filter 3 are pressed together, the left and right edges of the color filter 3 abut against the first receiving portions 13, causing the color filter 3 to cover the light-transmitting opening 14. A second receiving portion 15 extending circumferentially along the color wheel 1 is connected between the outer ends of adjacent first receiving portions 13. When the elastic sheet 21 and the color filter 3 are pressed together, the rear edge of the color filter 3 abuts against the second receiving portion 15. The color wheel 1 body, the first receiving portions 13, and the second receiving portions 15 mutually form the light-transmitting opening 14. They, together with the elastic sheet 21, complete the pressing and fixing of the color filter 3, making the structure of the color wheel assembly more compact.

[0033] A stage light includes a light source and a color wheel assembly for optical coupling with the light source.
