[0027] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0029] Referring to Figure 1 , an embodiment of the present application provides a color wheel assembly 100, and the color wheel assembly 100 can be applied to lighting devices such as photographic lights, stage lights, and searchlights.

[0030] Referring to Figures 2 to 3 , in some embodiments, the color wheel assembly 100 includes a housing 10, a phosphor 20, an adapter 31, a heat insulation member 40, a driving module 50, and a fan blade 32. The phosphor 20 is thermally connected to the adapter 31, so that the heat generated by the phosphor 20 helps to be transferred to the adapter 31 for heat dissipation, which helps to reduce the heat accumulation of the phosphor 20 and helps to lower the temperature of the phosphor 20.

[0031] The adapter 31 is located inside the housing 10. The heat insulation member 40 is connected to the adapter 31, and the heat conductivity of the heat insulation member 40 is less than that of the adapter 31. The driving end of the driving module 50 is connected to the heat insulation member 40 and is adapted to drive the adapter 31 and the phosphor 20 to rotate through the heat insulation member 40. The fan blade 32 is connected to the adapter 31, and the phosphor 20 is disposed on the side of the adapter 31 facing away from the fan blade 32. The rotation of the driving end of the driving module 50 is adapted to drive the adapter 31 to rotate, and the adapter 31 drives the fan blade 32 to rotate. In this way, during the rotation of the fan blade 32, it can push the surrounding air, and the air will in turn give the fan blade 32 a reverse force, forming a flowing air current around the fan blade 32, so that the fan blade 32 can drive the surrounding air to flow, which helps to improve the convective heat transfer effect between the phosphor 20 and the surrounding air, and also helps to improve the convective heat transfer effect between the adapter 31 and the surrounding air, facilitating the heat of the phosphor 20 and the adapter 31 to be dissipated to the surrounding air more quickly. Since the phosphor 20 and the fan blade 32 are driven to rotate by the same driving module 50, it is not necessary to separately configure different driving structures for the phosphor 20 and the fan blade 32, which helps to reduce the number of parts and the space occupied inside the housing 10, thus contributing to the miniaturization of the color wheel assembly 100.

[0032] In addition, the heat insulation member 40 helps to reduce the heat generated by the phosphor 20 from being transmitted to the driving module 50 through the adapter 31, helps to reduce the thermal influence of the phosphor 20 on the driving module 50, and thus helps to reduce the situation where the driving module 50 fails due to overheating.

[0033] In some embodiments, the driving module 50 can be a driving motor, a motor, etc. structure, and the driving module 50 can also be a driving structure including a speed reducer.

[0034] In some embodiments, the heat insulation member 40 can be a metal part. In this way, it helps the heat insulation member 40 to have higher strength and toughness, and helps the heat insulation member 40 to better withstand mechanical stress during rotation while maintaining the integrity and stability of the structure.

[0035] In some embodiments, the material of the heat insulation member 40 can be stainless steel, which helps the heat insulation member 40 to have a lower heat conductivity, so that the heat insulation member 40 can better reduce the heat transfer of the adapter 31 to the driving module 50, thus helping to reduce the thermal influence of the phosphor 20 on the driving module 50.

[0036] In some embodiments, the phosphor 20 can be thermally connected to the adapter 31 by directly attaching to the adapter 31. For example, if the adapter 31 is generally in a flat plate shape, the phosphor 20 can be directly attached to the plane of the adapter 31. In other embodiments, the phosphor 20 can also be indirectly connected to the adapter 31 through a heat-conducting medium such as heat-conducting silicone grease, thereby facilitating the transfer of the heat of the phosphor 20 to the adapter 31 for heat dissipation.

[0037] In some embodiments, the phosphor 20 can be a reflective phosphor or a transmissive phosphor.

[0038] In some embodiments, the phosphor 20 can include a heat-conducting substrate 21 and a wavelength conversion layer 22. The heat-conducting substrate 21 is thermally connected to the side of the adapter 31 facing away from the fan blade 32, and the wavelength conversion layer 22 is disposed on the side of the heat-conducting substrate 21 facing away from the adapter 31. The thermal conductivity of the heat-conducting substrate 21 is greater than that of the adapter 31. In this way, the heat generated by the phosphor 20 helps to be transferred to the heat-conducting substrate 21 for heat dissipation. The heat-conducting substrate 21 can not only dissipate the heat to the surrounding air, but also transfer the heat to the adapter 31 and the fan blade 32 for heat dissipation, thereby helping to reduce the heat accumulation of the phosphor 20 and helping to reduce the temperature of the phosphor 20.

[0039] In some embodiments, the heat-conducting substrate 21 can be a ceramic part. The ceramic part has good thermal stability and a low coefficient of thermal expansion, which helps the heat-conducting substrate 21 to still maintain stable physical properties and is not easily deformed in a high-temperature environment.

[0040] In some embodiments, the adapter 31 can be a metal part. In this way, it helps the adapter 31 to have high strength and toughness, and helps the adapter 31 to better withstand mechanical stress during rotation while maintaining the integrity and stability of the structure.

[0041] In some embodiments, the material of the adapter 31 can be aluminum, copper, etc., which helps the adapter 31 to have a good heat-conducting effect.

[0042] In some embodiments, the adapter 31 can be provided with a plurality of ventilation holes 311. The plurality of ventilation holes 311 are spaced apart. Each ventilation hole 311 penetrates through the opposite sides of the adapter 31 and avoids the heat-insulating member 40. The plurality of ventilation holes 311 can all be located on the inner ring side of the phosphor 20 or the inner ring side of the fan blade 32.

[0043] Thus, the ventilation holes 311 help to increase the path of air flow, enhance the air flow inside the housing 10, and accelerate gas circulation, thereby contributing to improving the efficiency of convective heat dissipation. In addition, during the process of the phosphor 20 transferring heat to the adapter 31, since the position of the ventilation holes 311 avoids the connection area with the phosphor 20, less heat is generated by the phosphor 20. Further, due to the structural absence of the adapter 31 at the ventilation holes 311, and since the heat transfer efficiency of air is lower than that of the adapter 31, the heat transfer efficiency at the ventilation holes 311 is low, such that the ventilation holes 311 can serve as thermal resistance holes, thereby helping to reduce the heat transfer of the phosphor 20 to the driving module 50.

[0044] In the present application, the term "a plurality of" means greater than or equal to two. For example, the number of the ventilation holes 311 can be two, three, four, five, six or other numbers.

[0045] In some embodiments, the plurality of ventilation holes 311 can be distributed and arranged in a ring shape.

[0046] In some embodiments, the ventilation holes 311 can generally be in the shape of a round hole, an oval hole, a kidney-shaped hole, a long strip hole, a polygon or other shapes.

[0047] In some embodiments, there can be various ways to fix the fan blade 32 to the adapter 31. The fan blade 32 can be directly or indirectly connected to the fixing surface of the adapter 31. For example, the fan blade 32 can be connected to the side of the adapter 31 opposite to the phosphor 20, such that the rotation of the adapter 31 can drive the fan blade 32 to rotate. In some embodiments, the fan blade 32 can be connected to the driving module 20. There can be various ways to relatively fix the fan blade 32 to the driving end of the driving module 50. The fan blade 32 can be directly or indirectly connected to the driving end of the driving module 50. For example, the fan blade 32 can be connected to the driving end of the driving module 50, such that the driving end of the driving module 50 can drive the fan blade 32 to rotate.

[0048] In some embodiments, the fan blade 32 is connected to the driving end of the driving module 50. For example, the fan blade 32 can be connected to the outer cylindrical surface of the driving end of the driving module 50, and the fan blade 32 and the outer cylindrical surface of the driving end of the driving module 50 can be connected by fasteners such as screws and bolts.

[0049] In some embodiments, when the fan blade 32 is connected to the adapter 31 and the phosphor 20 is disposed on the side of the adapter 31 away from the fan blade 32, the phosphor 20 and the fan blade 32 are dispersed on both sides of the adapter 31, which not only helps to make more full use of the spatial positions on both opposite sides of the adapter 31, but also helps to avoid having the phosphor 20 and the fan blade 32 on the same side of the adapter 31 so that the heat around the phosphor 20 cannot be quickly dissipated, thereby contributing to better heat dissipation for the phosphor 20.

[0050] In some embodiments, the adapter 31 and the fan blade 32 can be an integrally formed structure, which helps to reduce the number of parts of the color wheel assembly 100, helps to eliminate additional assembly steps, simplifies the production process, reduces assembly errors, and improves production efficiency and product quality consistency. In addition, the integrally formed structure also helps to reduce the thermal expansion difference between the adapter 31 and the fan blade 32, helps to enhance the thermal stability of the adapter 31 and the fan blade 32, reduces the deformation or cracks of the adapter 31 and the fan blade 32 caused by temperature changes, and extends the service life.

[0051] In some embodiments, the adapter 31 and the fan blade 32 can be integrally formed by a mold.

[0052] In some embodiments, the fan blade 32 is detachably connected to the adapter 31. In this way, when the fan blade 32 is damaged or damaged due to abnormal stress, it is convenient for the user to specifically replace only the damaged fan blade 32 without replacing the adapter 31, which helps to reduce the maintenance cost.

[0053] In some embodiments, the fan blade 32 can be detachably connected to the adapter 31 through a snap structure, a fastener, etc. Among them, the fastener can be a screw, a bolt, etc.

[0054] In some embodiments, as Figure 4 shown, the fan blade 32 can be perpendicular to the adapter 31; or, as Figure 5 shown, the fan blade 32 and the adapter 31 can be inclined. In this way, the perpendicular or inclined setting of the fan blade 32 helps to optimize the flow path of the air flow, reduce the air resistance, and helps the adapter 31 to more effectively accelerate the gas flow in the housing 10 and improve the convective heat dissipation performance. In addition, the inclined fan blade 32 can disperse the mechanical stress generated during rotation, helps to reduce the risk of the fan blade 32 breaking or deforming, and helps to improve the stability and durability of the color wheel assembly 100.

[0055] In some embodiments, the number of the fan blades 32 can be multiple. The multiple fan blades 32 and the drive module 50 can be located on the same side of the adapter 31, and the multiple fan blades 32 can surround the drive module 50. In this way, it helps the air flow formed by the fan blades 32 to flow through the circumference of the drive module 50, improves the effect of the air flow, helps to reduce the heat accumulation of the drive module 50, and thus can better dissipate heat from the drive module 50 and improve the heat dissipation performance of the adapter 31.

[0056] In some embodiments, the height dimension of the fan blade 32 along the axial direction of the adapter 31 can be greater than, equal to, or less than the height dimension of the drive module 50 along the axial direction of the adapter 31.

[0057] Refer to Figures 2 to 3, in some embodiments, the phosphor 20, the adapter 31, and the heat insulator 40 can all be annular. The inner ring space 23 of the phosphor 20, the inner ring space 312 of the adapter 31, and the inner ring space 410 of the heat insulator 40 are sequentially connected. The driving module 50 is opposite to the inner ring space 312 of the adapter 31. In this way, it helps that the airflow formed by the adapter 31 can sequentially pass through the inner ring space 23 of the phosphor 20, the inner ring space 312 of the adapter 31, and the inner ring space 410 of the heat insulator 40 to exchange heat with the driving module 50, helps to increase the contact area between the driving module 50 and the airflow, helps to reduce the heat accumulation of the driving module 50, and helps to lower the temperature of the driving module 50.

[0058] In some embodiments, the adapter 31 can be generally annular. For example, the adapter 31 can be generally circular, elliptical, square, pentagonal, hexagonal, or other shapes.

[0059] In some embodiments, the heat insulator 40 can be generally annular. For example, the heat insulator 40 can be generally circular, elliptical, square, pentagonal, hexagonal, or other shapes.

[0060] In some embodiments, the housing 10 can be provided with at least one heat dissipation structure 11, and the heat dissipation structure 11 can include heat conducting columns, fins, heat conducting blocks, or heat conducting protrusions.

[0061] In this way, it helps to increase the contact area between the housing 10 and the air and accelerate the dissipation of the heat of the housing 10. In addition, the heat dissipation structure 11 can also play a role in strengthening the structure of the housing 10, helps to improve the mechanical strength and stability of the housing 10, and reduces the deformation caused by thermal expansion and contraction.

[0062] In some embodiments, as Figure 3 shown, the heat dissipation structure 11 can be located inside the housing 10, which helps to increase the contact area between the housing 10 and the air inside the housing 10 and helps the heat generated by the phosphor 20 and the driving module 50 to be transferred to the housing 10.

[0063] In some embodiments, as Figure 6 shown, the heat dissipation structure 11 can be located outside the housing 10, which helps to increase the contact area between the housing 10 and the outside air and dissipate the heat of the housing 10 to the outside air.

[0064] Refer to Figures 7 to 8, in some embodiments, the color wheel assembly 100 may further include a volute cover 61 and a cover 62 located within the housing 10. The volute cover 61 and the cover 62 together define an accommodation space 63. The adapter 31 is rotatably located within the accommodation space 63. The cover 62 is provided with an air inlet 621 communicating with the accommodation space 63, and the air inlet 621 is located on one axial side of the adapter 31. The volute cover 61 is provided with an air outlet 611 communicating with the accommodation space 63, and the air outlet 611 is located on one radial side of the adapter 31.

[0065] Thus, the volute cover 61 and the cover 62 help to guide the air flow along a predetermined path. For example, the air flow is guided to enter the accommodation space 63 through the air inlet 621, and after being accelerated by the adapter 31, it is discharged from the air outlet 611, which helps to form an effective air flow circulation, enhance the convection heat dissipation ability, improve the heat exchange efficiency of the fan blade 32 within the accommodation space 63, and improve the heat dissipation efficiency. In addition, the volute cover 61 and the cover 62 help to reduce the turbulence of the air flow during the flow process, reduce the generation of noise, help to provide a quieter operating environment, and help the color wheel assembly 100 to be applied to noise-sensitive scenarios.

[0066] In one embodiment, the color wheel assembly 100 may not be provided with a volute cover, and only the cover 62 is provided, which can also improve the heat exchange efficiency of the fan blade 32 and further improve the heat dissipation.

[0067] Furthermore, the volute cover 61 is also provided with a first screw hole for fixing to the housing 10 and a second screw hole 613 for fixing to the cover 62. The volute cover 61 is fixed to the housing 10 by means of screw locking, and the cover 62 is fixed to the volute cover 61 by means of screw locking.

The lighting device 1000 may be a photographic lamp, a stage lamp, a searchlight, etc. The lighting device 1000 includes a laser light source 200 and the color wheel assembly 100 in any of the above embodiments.
