[0006] In some embodiments of this application, the volume of the reflective cavity of the second cover is larger than the volume of the first cover, so that the first cover can be accommodated in the second cover after disassembly.

[0007] In some embodiments of this application, the quick-release assembly includes a limiting part and a locking part; the limiting part is respectively disposed on the end faces of the first cover and the second cover, and is used to limit the axial movement of the first cover and the second cover; the locking part is also disposed on the end faces of the first cover and the second cover, and is used to limit the circumferential rotation of the first cover and the second cover when they rotate to a predetermined position.

[0008] In some embodiments of this application, the limiting part includes a limiting groove and a limiting buckle; the limiting groove is disposed on the end face of the light-emitting end of the first cover, and the limiting groove includes a docking groove and a limiting groove that are interconnected, the limiting groove extending circumferentially along the first cover; the limiting buckle is disposed on the end face of the light-incoming end of the second cover and corresponds to the limiting groove; the limiting buckle can be inserted into the docking groove along the axial direction and rotated into the limiting groove to axially limit the first cover and the second cover.

[0009] In some embodiments of this application, the locking part includes a pusher and a locking hole. The locking hole is disposed on the end face of the light-emitting end of the first cover. The pusher is disposed on the end face of the light-incoming end of the second cover. The pusher can move along the axial direction of the second cover to insert into the locking hole, so as to circumferentially lock the first cover and the second cover.

It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Please see Figures 1 to 8 This embodiment provides a reflector 100, which includes a plurality of covers 10 and a quick-release assembly 20 connecting the plurality of covers 10.

[0028] Multiple reflectors 10 are arranged sequentially along the direction of light emission. Each reflector 10 has a reflective cavity with openings at both ends, and the inner wall of the reflective cavity is a reflective surface. The curvature of the reflective surface of different reflectors 10 is different. Quick-release components 20 are disposed on the end faces of adjacent reflectors 10 for detachably connecting adjacent reflectors 10. This allows the reflector 100 to adjust its overall light emission angle by adding or removing reflectors 10 or replacing reflectors 10 with different reflective surface curvatures, thereby obtaining different light-gathering effects.

[0029] Specifically, users can add or remove segments of the reflector 10 or replace segments of the reflector 10 with different curvatures to obtain different overall light emission angles according to different shooting needs. Different light-gathering effects can be achieved without replacing the entire reflector 100, reducing the amount of material carried and the cost of use for users. At the same time, the quick-release assembly 20 ensures a reliable connection between the reflectors 10, making the installation and removal of the reflector 100 simple and quick, and improving the efficiency of the reflector 100 in actual shooting scenarios.

[0030] Please see Figure 7 In some embodiments, each housing 10 includes an outer shell 101, a reflector 102, a fixing strip 103, and a fixing plate 104. The outer shell 101 is hollow inside with openings at both ends. The reflector 102 is disposed inside the outer shell 101, and multiple reflectors 102 are arranged side by side along the circumference of the outer shell 101, with the side facing away from the outer shell 101 being the reflective surface. The fixing strip 103 is disposed at the connection point of adjacent reflectors 102 to fix adjacent reflectors 102 together to form a reflective cavity. The fixing plate 104 is disposed at both ends of the outer shell 101 to abut and limit the reflectors 102.

[0031] Specifically, the outer shell 101 is a cylindrical structure with open ends and a hollow interior, used to house the internal optical components of the cover 10 and provide overall mechanical support. Reflectors 102 are disposed within the outer shell 101, with multiple reflectors 102 arranged side-by-side along the circumference of the outer shell 101. The inner surface of each reflector 102 is processed or coated with a highly reflective layer, and the side facing away from the outer shell 101 forms a reflective surface. Multiple reflectors 102 are joined together circumferentially to form a complete reflector cup, allowing light to be reflected axially within the reflector cup and ultimately emitted from the light-emitting end 106 of the cover 10. Adjacent reflectors 102 are connected by fixing strips 103, each fixing strip 103 located at the junction of two reflectors 102. The fixing strips 103 can be connected by snap-fit, riveting, screwing, or welding, forming a stable spliced ​​structure of the reflectors 102 in the circumferential direction. Fixing plates 104 are provided at both ends of the cover 10 to limit and abut the end of the reflector 102. The fixing plates 104 can press tightly against the end face of the reflector 102 to keep the reflector 102 stable in the axial direction and prevent it from loosening due to vibration, movement or thermal deformation.

[0032] Please see Figures 1 to 4 In some embodiments, the reflector 100 includes a first cover 11 and a second cover 12 arranged sequentially along the direction of light emission. The light-inlet end 105 of the second cover 12 matches the light-outlet end 106 of the first cover 11; the curvature of the reflective surface of the second cover 12 is smaller than the curvature of the reflective surface of the first cover 11.

[0033] Specifically, this embodiment has two covers 10, namely a first cover 11 and a second cover 12. The first cover 11 includes a reflective cavity that expands in a trumpet shape, and its reflective surface is a large arc surface, which can perform primary focusing of the light entering it. For example, the exit angle of the light emitted through the first cover 11 can be 30°. The second cover 12 is disposed at the light-emitting end 106 of the first cover 11, and the size of its light-inlet end 105 is matched with the light-emitting end 106 of the first cover 11 to ensure that the axis of the reflective cavity can be precisely aligned after the two are spliced. The reflective surface of the second cover 12 can adopt a structure with a smaller arc, and its reflective surface is more gentle. For example, the exit angle of the light emitted through the second cover 12 is 15°, thereby performing secondary focusing of the light after the primary focusing by the first cover 11.

[0034] The first enclosure 11 converges the light from a wide divergence angle range to a medium angle range, while the second enclosure 12 further adjusts the light exit angle and significantly improves the brightness at the center of the beam. It is suitable for stage applications where there is frequent switching between long-range and short-range beams.

[0035] In other embodiments, the reflector 100 may also be provided with a third, fourth, fifth, etc., and the curvature of the reflective surface of each reflector may gradually change. Users can selectively install multiple reflectors 10 according to the actual usage environment to adapt to different usage environments.

[0036] Please see Figure 3 and Figure 4 In some embodiments, the volume of the reflective cavity of the second cover 12 is larger than the volume of the first cover 11, so that the first cover 11 can be accommodated in the second cover 12 after disassembly.

[0037] Specifically, when the reflector 100 needs to be transported or stored for an extended period, the user can first separate the two covers 10 using the quick-release assembly 20, and then directly insert the smaller first cover 11 into the interior of the second cover 12, with flexible foam providing insulation. This effectively reduces space occupation and improves portability during transportation, outdoor shooting, or warehousing, while also reducing the risk of collisions caused by stacking multiple items. It is particularly suitable for scenarios requiring frequent handling, such as photography lighting equipment and outdoor supplementary lighting equipment, and has significant practical value.

[0038] Please see Figure 3 and Figure 4In some embodiments, the quick-release assembly 20 includes a limiting part 21 and a locking part 22. The limiting part 21 is respectively disposed on the end faces of the first cover 11 and the second cover 12 to limit the axial movement of the first cover 11 and the second cover 12; the locking part 22 is disposed on the end faces of the first cover 11 and the second cover 12 to limit their circumferential rotation when the first cover 11 and the second cover 12 are rotated to a predetermined position.

[0039] In use, the user can first align the light-inlet end 105 of the second cover 12 with the light-outlet end 106 of the first cover 11, so that the end faces of the two are in contact with each other. The limiting part 21 on the end faces of the first cover 11 and the second cover 12 forms an effective axial positioning. After completing the axial positioning, the user then rotates the second cover 12 in the circumferential direction. During the rotation, the locking parts 22 of the first cover 11 and the second cover 12 engage with each other, so that the two covers 10 are not only restricted by the abutment of the limiting part 21 in the axial direction, but also firmly fixed by the locking part 22 in the circumferential direction, so as to maintain a coaxial and stable splicing relationship and prevent relative rotation or loosening due to vibration or movement.

[0040] Please see Figure 3 , Figure 4 and Figure 7 In some embodiments, the limiting part 21 includes a limiting groove 211 and a limiting buckle 212. The limiting groove 211 is disposed on the end face of the light-emitting end 106 of the first cover 11, and includes a connecting groove 2111 and a limiting groove 2112 that are interconnected. The limiting groove 2112 extends circumferentially along the first cover 11. The limiting buckle 212 is disposed on the end face of the light-entry end 105 of the second cover 12 and corresponds to the limiting groove 211. The limiting buckle 212 can be inserted into the connecting groove 2111 along the axial direction and rotated into the limiting groove 2112 to limit the axial movement of the first cover 11 and the second cover 12.

[0041] Specifically, multiple limiting buckles 212 are provided, which surround the end face of the fixing plate 104 of the light-inlet end 105 of the second cover 12. The overall structure of the limiting buckles 212 is T-shaped. Multiple limiting grooves 211 are also provided, which surround the end face of the fixing plate 104 of the light-outlet end 106 of the first cover 11, so that they can correspond one-to-one with the limiting buckles 212. Among them, the limiting groove 211 includes a docking groove 2111 that opens along the axial direction of the first cover 11, and a limiting groove 2112 that communicates with the docking groove 2111 and extends circumferentially along the first cover 11. The width of the docking groove 2111 is slightly larger than the outer dimensions of the limiting buckle 212, so that the limiting buckle 212 can be smoothly inserted into the limiting groove 211. The width of the limiting slot 2112 is smaller than the outer dimensions of the limiting buckle 212, which restricts the axial movement freedom between the first cover 11 and the second cover 12 when the limiting buckle 212 rotates to the limiting slot 2112 section.

[0042] When splicing the two covers 10, the light-inlet end 105 of the second cover 12 can be aligned with the light-outlet end 106 of the first cover 11, so that the end faces of the fixing plates 104 of the two are close to each other. At this time, the limiting buckle 212 is aligned with the mating groove 2111 of the limiting groove 211. The user pushes the second cover 12 in the axial direction so that the limiting buckle 212 enters the mating groove 2111 of the first cover 11. Subsequently, the second cover 12 can be rotated relative to the first cover 11 in the circumferential direction. For example, the second cover 12 can be rotated clockwise so that the limiting buckle 212 moves along the extension direction of the limiting groove 2112. When the limiting buckle 212 slides into the limiting groove 2112 and reaches the end position of the limiting groove 2112, a stable and reliable axial limiting is formed.

[0043] Please see Figure 3 , Figure 4 and Figure 7 In some embodiments, the locking part 22 includes a pusher 222 and a locking hole 221. The locking hole 221 is disposed on the end face of the light-emitting end 106 of the first cover 11; the pusher 222 is disposed on the end face of the light-entering end 105 of the second cover 12, and the pusher 222 can move along the axial direction of the second cover 12 to insert into the locking hole 221, so as to circumferentially lock the first cover 11 and the second cover 12.

[0044] Furthermore, such as Figure 6 and Figure 8As shown, the pusher 222 includes a pusher seat 2221, a pusher pin 2222, a pusher handle 2223, and an elastic member 2224. The pusher seat 2221 is fixed inside the second cover 12, and the pusher pin 2222 passes through the pusher seat 2221 and can reciprocate along the axial direction of the second cover 12. One end of the pusher handle 2223 is fixedly connected to the pusher pin 2222, and the other end passes through the second cover 12 radially, for driving the pusher pin 2222 to move to insert or withdraw from the lock hole 221. The elastic member 2224 is disposed between the pusher pin 2222 and the pusher seat 2221, for pushing the pusher pin 2222 to automatically extend to the end face of the light-entry end 105 of the second cover 12.

[0045] Specifically, a fixing plate 104 is provided on the light-emitting end 106 of the first cover 11, and a locking hole 221 is formed on the end face of the fixing plate 104. The locking hole 221 is a through hole extending along the axial direction of the first cover 11, and the diameter of the hole is slightly larger than the outer diameter of the front end of the pusher 222, so that the pusher 222 can be smoothly inserted without jamming. The position of the locking hole 221 corresponds to the position of the pusher 222 on the second cover 12.

[0046] When the first cover 11 and the second cover 12 are aligned and rotated circumferentially to a preset position, the front end of the push pin 2222 is directly opposite the locking hole 221 on the fixing plate 104 of the first cover 11. Since the diameter of the locking hole 221 is slightly larger than the outer diameter of the push pin 2222, the push pin 2222 will automatically enter the locking hole 221 under the push of the elastic element 2224. At this time, the circumferential rotation between the first cover 11 and the second cover 12 is locked, and the first cover 11 and the second cover 12 are in a locked state, completing the splicing and fixing.

[0047] When it is necessary to disassemble the first cover 11 and the second cover 12, the user only needs to use their finger to move the push handle 2223 towards the light emission direction, thereby causing the push pin 2222 to retract along the axial direction. After the push pin 2222 exits the locking hole 221, the rotation limit between the first cover 11 and the second cover 12 is released, and the user can then rotate the second cover 12 in the opposite direction to return the limit buckle 212 to the docking slot 2111 position, completing the disassembly.

[0048] It should be understood that the relative positions of the limiting groove 211 and the limiting buckle 212, and the locking hole 221 and the pusher 222 on adjacent covers 10 in this embodiment can be interchanged.

[0049] Please see Figure 2 and Figure 6In some embodiments, a handle 121 is provided on the outer side of the second cover 12. The two ends of the handle 121 are connected to the outer side of the second cover 12, so that a gap space for gripping is formed between the handle 121 and the second cover 12; the handle 121 is located in the moving extension path of the push handle 2223 and is close to the push handle 2223.

[0050] Specifically, the handle 121 is positioned on the side corresponding to the direction of the push handle 2223, so that when the operator holds the handle 121, he can easily reach the push handle 2223 with his thumb, thereby completing the push action in the same grip position.

[0051] For example, when it is necessary to disassemble the first cover 11 and the second cover 12, the operator's fingers can, while maintaining a grip on the handle 121, directly push the pusher handle 2223 near the handle 121, causing the pusher pin 2222 to retract along the axial direction of the second cover 12 and exit the lock hole 221. At this time, the operator's hand is still on the handle 121, and can continue to apply rotational force under the control of the same hand, causing the second cover 12 to rotate in the direction of releasing the limit buckle 212, thereby achieving quick unlocking and separation.

[0052] Please see Figure 2 and Figure 4 In one embodiment, a bayonet 111 is provided on the end face of the light-inlet end 105 of the first cover 11. The bayonet 111 is used to connect with the camera lamp to fix the reflector 100 on the light outlet of the camera lamp.

[0053] The light-inlet end 105 of the first reflector 11 does not have a fixing plate 104, but is fixed with a bayonet 111, which is used to connect with a camera light. In use, the user only needs to align the bayonet 111 of the reflector 100 with the corresponding bayonet interface on the outside of the light outlet of the camera light, and then rotate it in a preset direction to make the bayonet 111 engage with the camera light, thereby ensuring that the reflector 100 is securely installed at the light outlet of the camera light.

[0054] In summary, this embodiment provides a reflector 100, which includes multiple cover bodies 10 arranged sequentially along the light direction and a quick-connect assembly connecting adjacent cover bodies 10. Each cover body 10 has a different curvature of its reflective surface, allowing users to easily add or remove segments of the cover body 10 or replace segments of the cover body 10 with different curvatures via the quick-release assembly 20. This enables the reflector 100 to adjust the light emission angle by splicing different cover body 10 segments, thereby meeting users' needs for different light-gathering effects. It achieves multiple optical effects without replacing the entire reflector 100, effectively improving usage efficiency and reducing the purchase and carrying costs of reflector 100 accessories.

[0055] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
