It should be understood that the present application can be implemented in various ways, and all of the changes thereof do not deviate from the scope of the present application, and the description and drawings in the essence are used as a description, not to limit the present application.

[0028] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of direction or position relationship (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation. When these elements are in the position shown in the drawings, these descriptions are appropriate. If the position of these elements changes, the indications of these directions also change accordingly.

[0029] In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0030] The conventional reflector cup needs to be inserted from the top or bottom of the shell for installation, and the operation space is limited, the installation process is complicated, and the technical problem of deformation or position deviation of the reflector cup is easily caused.

[0031] Please refer to Figures 1 to 7 In some embodiments, a reflector cover 100 is provided, which includes a shell 110 and a reflecting plate 120.

[0032] The shell 110 includes at least two bases 111, and each base 111 includes opposite inner and outer side walls 112 and 113. The bases 111 can be spliced together in a circumferential direction, so that the inner side walls 112 of the bases 111 enclose a hollow channel. The reflecting plates 120 are fixed to the inner side walls 112 of the bases 111, and the reflecting plates 120 have a light-reflecting surface on a side facing away from the bases 111. When the bases 111 are spliced together, the light-reflecting surfaces of the reflecting plates 120 on the bases 111 enclose a light-reflecting cavity. The light-reflecting cavity has a light inlet 115 and a light outlet 116 at two ends thereof. Light enters the light-reflecting cavity from the light inlet 115, and is reflected by the light-reflecting surfaces and then emitted from the light outlet 116.

[0033] Specifically, the shell 110 is formed by a plurality of bases 111 that are spliced together in a circumferential direction. The bases 111 can be made of aluminum alloy, heat-resistant plastic, or carbon fiber composite material, which can ensure lightweight and good high-temperature resistance. The inner side walls 112 of the bases 111 enclose a complete hollow channel, and the hollow channel has open ends. The reflecting plates 120 can be fixed to the inner walls of the hollow channel to enclose a light-reflecting cavity. The light inlet 115 of the light-reflecting cavity is used to receive light emitted by an external light source, and the light outlet 116 is used to output the light after reflection.

[0034] During assembly, the reflecting plates 120 can be first installed on the open inner side walls 112 of the bases 111, so that the user can complete the installation of the reflecting plates 120 in an open environment, ensure the accuracy of the position, and avoid problems such as installation difficulty or damage to the light-reflecting surface caused by the closure of the shell 110. This improves the convenience and accuracy of assembly. In addition, the split shell 110 also makes the manufacturing, transportation, and storage of the light-reflecting cover 100 more convenient.

[0035] Further, by fixing the reflecting plates 120 to the inner walls of the bases 111 to enclose a light-reflecting cavity, compared with a traditional aluminum light-reflecting cup that is integrally formed by spinning, the spliced reflecting plates 120 do not need to be spun on the surface, and the reflecting plates 120 will not be damaged due to shape processing. This can break through the limitation of material processing and greatly improve the light-reflecting rate of the light-reflecting cover 100.

[0036] Please refer to Figure 2 and Figure 3 In some embodiments, the shell 110 further includes a connecting portion 114 disposed on the outer side wall 113 of each base 111. The connecting portion 114 is used to fix two adjacent bases 111, so that the bases 111 can be spliced together in a circumferential direction.

[0037] The connecting part 114 is arranged on the outer side wall 113 of the base 111, and is used to connect adjacent bases 111, so that the bases 111 can be firmly spliced, and displacement or looseness in the splicing process is avoided, thereby ensuring the structural stability and optical performance consistency of the entire reflector 100.

[0038] It is conceivable that the connecting part 114 can have different structures. For example, the connecting part 114 can have a buckle structure, and the connecting mode of the buckle structure can realize quick assembly and disassembly of the bases 111, and is suitable for application scenarios in which the bases 111 need to be conveniently replaced. The connecting part 114 can also have a sliding rail fitting structure, and smooth butt joint of adjacent bases 111 is realized by fitting the sliding rail into the sliding groove.

[0039] Please refer to Figure 4 In some embodiments, the connecting part 114 includes a boss 1141 and a locking piece 1142. The boss 1141 is arranged on both side edges of the outer side wall 113 of the base 111 and protrudes away from the base 111, and the boss 1141 is internally provided with a through hole. The locking piece 1142 is arranged in the through hole of the boss 1141 of the adjacent base 111, so as to fix the two adjacent bases 111.

[0040] Specifically, the connecting part 114 is composed of the boss 1141 and the locking piece 1142. Each side edge of the base 111 can be provided with a plurality of bosses 1141 arranged at intervals along the axis direction, so as to enhance the fixation between the bases 111. The boss 1141 protrudes away from the base 111, thereby providing installation space for the locking piece 1142. The boss 1141 is internally provided with a through hole, and after the through holes of the bosses 1141 of the adjacent bases 111 are aligned, the locking piece 1142 penetrates through the through hole, thereby fixing the adjacent bases 111 together, so that they can be spliced in turn in the circumferential direction, and finally form a complete shell 110.

[0041] In some embodiments, the locking piece 1142 can have different structures such as bolts, pins, screws and the like, so as to adapt to different fastening requirements. For example, the bolt connection of the boss 1141 is suitable for scenarios with high stability requirements, and can provide strong impact resistance and ensure that it will not loosen after long-term use. The pin connection is convenient for quick disassembly and assembly, and is suitable for occasions in which the bases 111 need to be frequently replaced or adjusted. Of course, the locking piece 1142 can only realize detachable connection between the bases 111, and is not limited in this regard.

[0042] Please refer to Figure 4 In some embodiments, two bases 111 are provided, and the inner side wall 112 of each base 111 includes a plurality of mounting surfaces 1121; the mounting surfaces 1121 are arranged side by side along the circumference of the base 111, and the included angle between adjacent mounting surfaces 1121 is less than 180°.

[0043] Further, each base 111 is provided with a plurality of reflection plates 120, which are arranged one-to-one with the mounting surfaces 1121 on the base 111, so that the reflection plates 120 are fixedly mounted on the corresponding mounting surfaces 1121 with the side away from the light-reflecting surface.

[0044] Specifically, the shell 110 is formed by splicing two bases 111, and the two bases 111 have basically the same structure. The inner side wall 112 of each base 111 is composed of a plurality of mounting surfaces 1121, which are arranged in sequence along the circumference of the base 111 and extend along the axial direction of the base 111 to form a platform for fixing the reflection plates 120. This allows the reflection plates 120 to remain stable when mounted on the base 111 and ensures the fit with the base 111.

[0045] The included angle between adjacent mounting surfaces 1121 on the base 111 is less than 180°, so that the mounting surfaces 1121 can smoothly enclose the hollow channel after the two bases 111 are connected. During splicing, since the mounting surfaces 1121 of each base 111 are pre-angled, the reflection plates 120 can be directly attached to the mounting surfaces 1121 of the base 111, thereby simplifying the assembly steps and improving the assembly efficiency.

[0046] Meanwhile, the mounting surfaces 1121 are arranged one-to-one with the radiation plates, and the reflection plates 120 are first mounted on each mounting surface 1121 one by one, so that the installation position of the reflection plates 120 is more accurate, reducing the problem of misalignment or looseness of the reflection surface that may occur during assembly of the traditional overall light-reflecting cover 100. The reflection plates 120 can be closely attached to the inner side wall 112 of the base 111, thereby forming a continuous light-reflecting cavity and ensuring the consistency of the overall optical effect of the light-reflecting cavity, further improving the reflectivity of light.

[0047] In some embodiments, the reflection plates 120 can be fixed to the mounting surfaces 1121 on the base 111 by adhesion, screw fixation, magnetic attraction, or embedding, etc.

[0048] It is conceivable that in some other embodiments, the base 111 can also be provided with a mounting rack or heat-conducting silica gel, and the reflection plates 120 can be mounted on the mounting rack or heat-conducting silica gel and fixed to the base 111 through the mounting rack or heat-conducting silica gel, thereby achieving the installation of the reflection plates 120.

[0049] It is conceivable that in other embodiments, the number of bases 111 can also be the same as the number of reflective plates 120, which can be set to three, four or five or more. Each base 111 can only have one mounting surface 1121, and each mounting surface 1121 corresponds to the installation of one reflective plate 120; several bases 111 with reflective plates 120 are spliced together to form a reflector 100. When a certain reflective plate 120 is damaged, the damaged reflective plate 120 and the base 111 fixed thereto can be disassembled and replaced together, that is, the damaged reflective plate 120 can be replaced without disassembling the entire reflector 100, greatly reducing the maintenance cost.

[0050] Referring to Figures 5 to 7 In some embodiments, the hollow channel formed by the inner side wall 112 of the base 111 gradually increases in diameter along the direction of light emission. The width of the mounting surface 1121 and the reflective plate 120 gradually increases along the direction of light emission.

[0051] Specifically, the width of the mounting surface 1121 on each base 111 gradually increases from the light inlet 115 to the light outlet 116, so that the hollow channel formed thereby is a gradually expanding cavity structure. Correspondingly, the shape of the reflective plate 120 is the same as the size of the mounting surface 1121, that is, when the reflective plate 120 is attached to the mounting surface 1121, the reflective surface of the reflective plate 120 forms a reflective cavity which is also a gradually expanding cavity structure. This allows the light to be gradually distributed to a larger area during reflection, reducing the risk of excessive local light or uneven illumination.

[0052] Referring to Figure 7 In some embodiments, the mounting surface 1121 on the base 111 can be provided as a curved surface; the reflective plate 120 is correspondingly provided as an arc-shaped panel. That is, the mounting surface 1121 and the reflective plate 120 have a curvature along the axis direction of the housing 110. At this time, the reflective surface of the reflective cavity is an arc-shaped cavity that gradually increases in the direction of the light outlet 116, and the curvature of the reflective plate 120 and the mounting surface 1121 can be adjusted according to the actual need for light concentration. Of course, in other embodiments, the mounting surface 1121 on the base 111 can be a flat surface, and the reflective plate 120 can also be a flat panel to adapt to different light concentration needs.

[0053] It is conceivable that in other embodiments, when the base 111 has multiple mounting surfaces 1121, the mounting method of the reflector 120 can be different. For example, each mounting surface 1121 can not only individually mount one reflector 120, thus mounting multiple reflectors 120 on one base 111, but it can also adopt an integral reflector 120 structure. For example, the multiple reflectors 120 corresponding to each base 111 can be connected to each other at the wider end to form an integral sawtooth structure. That is, the multiple reflectors 120 are connected as one unit at the large-diameter end and separated at the small-diameter end, making the multiple reflectors 120 an integrated component.

[0054] When the integrated reflector 120 is bent, its various bent sections can accurately fit onto the multiple mounting surfaces 1121 of the base 111, thereby reducing installation steps and allowing the reflector 120 of a base 111 to be fixed in one go. The integrated reflector 120 can be directly formed on a single piece of metal or composite material sheet through processing techniques such as die-cutting, laser cutting, or etching, ensuring that it can adapt to the structure of the base 111 after bending. This not only reduces the number of assembly steps for individual reflectors 120 and improves production efficiency, but also enhances the stability of the overall structure and avoids misalignment or loosening problems that may occur during the installation of individual reflectors 120.

[0055] In some embodiments, the reflector 120 includes a substrate layer, a reflective layer, and a protective layer. The reflective layer is disposed on the side of the substrate layer opposite to the base 111 to form a reflective surface; the protective layer covers the reflective layer to protect it.

[0056] Specifically, the substrate layer can be made of aluminum alloy, which serves as the main structure of the reflector 120, providing necessary support to ensure its stable shape. The reflective layer is located on the side of the substrate layer facing away from the base 111. This reflective layer can be applied to the substrate layer using processes such as aluminum plating or vacuum evaporation to obtain a highly reflective metallic film. The reflective layer effectively improves light reflection efficiency, reduces light loss, and ensures that the light entering the reflective cavity is fully utilized. The protective layer can be a transparent oxide film, a wear-resistant coating, or a polymer protective film to provide resistance to corrosion, moisture, and mechanical damage, preventing oxidation, scratches, or contamination of the reflective layer.

[0057] Through a multi-layered composite structure design consisting of a substrate layer, a reflective layer, and a protective layer, the reflector 120 achieves high reflectivity and durability. It is suitable for various environments and can be widely used in different types of reflectors 100, thereby improving the overall reliability of the reflector 100.

[0058] In some embodiments, the reflective layer may also be texture-optimized according to different application requirements to form microstructures such as scales to adjust the light emission angle, thereby improving the uniformity of light or adjusting the beam angle.

[0059] In some embodiments, the reflective layer is a pure silver film electroplated on the substrate layer. Compared to traditional aluminum or chromium-plated reflective layers, the silver film can significantly reduce light absorption loss and improve light output efficiency, making it particularly suitable for applications with extremely high requirements for light energy utilization, such as high-brightness lighting projection equipment or other precision optical equipment.

[0060] Furthermore, the reflective cavity in this embodiment is formed by splicing multiple reflective plates 120. Each sheet-like reflective plate 120 can be coated individually, thereby ensuring the uniformity of the coating. This further improves the reflection efficiency of the reflective cavity, minimizes the energy loss of light after reflection, and effectively enhances the output brightness of the light source.

[0061] Please see Figure 4 In some embodiments, the housing 110 further includes a bayonet 130, which includes a bayonet body 131 and a limiting block 132. The bayonet body 131 is disposed at one end of the light inlet 115 of the base 111, and the limiting block 132 protrudes from the outer surface of the bayonet body 131. When multiple bases 111 are spliced ​​together, the bayonet bodies 131 on the base 111 form an annular retaining ring for engaging with the photographic lighting fixture 200.

[0062] Specifically, the bayonet body 131 can be integrally formed on the base 111. When multiple bases 111 are spliced ​​together in the circumferential direction to form a complete reflector 100, the bayonet bodies 131 on each base 111 are also spliced ​​together and enclosed to form a complete annular retaining ring. The outer side of the retaining ring has a limiting block 132, which can be engaged with the accessory bayonet 220 on the photographic light fixture 200.

[0063] It is conceivable that in some other embodiments, the bayonet body 131 can also be detachably connected to the base 111, so that different bayonet components 130 can be connected to the base 111. Based on this example, the bayonet component 130 can also be a complete annular retaining ring. After multiple bases 111 are spliced ​​together to form the housing 110 of the reflector 100, the integrated bayonet component 130 is then fixed to the end face of the housing 110 to realize the connection between the reflector 100 and the photographic light fixture 200.

[0064] Please see Figure 1 This embodiment also provides a photographic lighting system, which includes a photographic light fixture 200 and a reflector 100 as described above.

[0065] The photographic lighting fixture 200 includes a housing 210, a light source assembly 250 disposed within the housing 210, and an accessory slot 220 disposed on the housing 210. The light source assembly 250 has a light mixing cavity 253, and the accessory slot 220 has a light-transmitting hole, which is positioned opposite to the light source assembly 250. One end of the light inlet 115 of the reflector 100 is detachably connected to the accessory slot 220, allowing light emitted from the light source assembly 250 to exit through the light-transmitting hole of the accessory slot 220, enter the reflector 100 through the light inlet 115, and exit through the light outlet 116 after reflection by the reflective surface.

[0066] Specifically, the housing 210 of the photographic lighting fixture 200 encloses its internal structure and provides physical support. The bottom surface of the housing 210 is equipped with support feet 240, allowing it to be stably placed on the ground. The top surface of the housing 210 is equipped with a handle 230 for easy carrying and movement. Support frames 260, which are U-shaped, are also connected to both sides of the housing 210. These support frames provide mounting points for the photographic lighting fixture 200, enabling it to be mounted on tripods, hanging devices, or other auxiliary support devices, thus expanding its application scenarios.

[0067] The light source assembly 250 is disposed inside the housing 210. The light source assembly 250 can be an LED lamp, a xenon lamp, or other light source, capable of producing stable and high-intensity illumination. An accessory bayonet 220 is located on the housing 210, and can connect to various optical accessories, such as a reflector 100, a diffuser, or other accessories. The accessory bayonet 220 has a light-transmitting hole, allowing light emitted from the light source assembly 250 to pass smoothly through the light-transmitting hole, exit the housing 210, and enter the connected optical accessory.

[0068] Please see Figure 8 In one example, the light source assembly 250 includes a light panel 251 and a light shaping component 252. Multiple light-emitting chips are integrated on the light panel 251. The light shaping component 252 is disposed within the housing 210 of the photographic lighting fixture 200 and above the light panel 251. The light shaping component 252 forms a light source mixing cavity 253. Light emitted from the multiple light-emitting chips is mixed in the mixing cavity 253 and then emitted towards the outside of the photographic lighting fixture 200. A light source lens 254 can be further disposed on the light-emitting side of the mixing cavity 253. The mixing cavity 253 built into the photographic lighting fixture 200 can perform primary light shaping on the light-emitting area, light spot outline, and / or light emission angle of the light source, and secondary light shaping through an externally detachable reflector 100. Different lighting requirements for shooting can be achieved by selecting reflectors 100 with different angles or reflectivities.

[0069] In some examples, the light shaping component 252 built into the photographic lighting fixture 200 can be a light source reflector or a light source retainer, etc. In some examples of this application, the light shaping of the photographic lighting fixture 200 by the reflector 100 includes the adjustment of the light emission angle. For example, different reflectors 100 can achieve various light emission angle adjustments such as 25 degrees, 30 degrees, 45 degrees, 50 degrees, 60 degrees, and 75 degrees.

[0070] In some embodiments, the accessory bayonet 220 is provided with a mating groove for accommodating the bayonet member 130. Multiple limiting grooves are formed on the sidewall of the mating groove, and the limiting block 132 can rotate into the limiting groove to fix the reflector 100 to the photographic light fixture 200. When the light emitted by the light source assembly 250 passes through the light-transmitting hole of the accessory bayonet 220, the light enters the interior of the reflector 100 from the light inlet 115, is reflected on the reflective surface inside the reflector 100, and finally exits from the light outlet 116, achieving uniform guidance or enhancement of the light.

[0071] In summary, this application provides a reflector 100 and a photographic light system, which includes a housing 110 and a reflector 120. The housing 110 is formed by multiple bases 111 that are spliced ​​together along the circumferential direction. The inner walls of the bases 111 are open before splicing, allowing the user to fix the reflector 120 to the bases 111 in a more spacious working area. After the bases 111 are spliced, the fixed reflector 120 forms a complete reflective cavity, which ensures that the reflector 120 is stably and accurately installed on the bases 111, avoiding misalignment of the reflector due to space constraints, improving the convenience and accuracy of assembly, and further improving reflectivity.
