Abstract
Description
Technical Field
[0001] This utility model relates to the field of photographic and video equipment technology, and in particular to a reflector and photographic light system. Background Technology
[0002] In the fields of film, photography, and stage lighting, reflectors are an important accessory for lighting fixtures. They are mainly used to collect, focus, and guide light to improve the illuminance and luminous efficacy of the fixtures.
[0003] Traditional reflectors are typically manufactured using a spinning process to create the aluminum reflective cup inside. High-speed spinning causes the aluminum sheet to gradually deform along the mold, ultimately forming a cup-shaped structure with a smooth inner wall.
[0004] However, during the spinning process, the aluminum material undergoes plastic deformation under stress, which affects its surface microstructure, making it difficult to maintain a high degree of smoothness on the inner wall surface. Even after subsequent polishing or anodizing, its maximum reflectivity remains relatively low, typically only reaching around 80%, and further breakthroughs are not possible. Utility Model Content
[0005] One objective of this invention is to solve the technical problem of low reflectivity of the reflector cup inside a traditional reflector.
[0006] To address the aforementioned technical problems, this application provides a reflector, comprising: a housing having an internally hollow cavity with openings at both ends; and a reflector cup housed within the cavity, the reflector cup including multiple reflective plates arranged circumferentially around the cavity, the sides of adjacent reflective plates being interconnected and fixed, the multiple reflective plates being spliced together to form a cylindrical reflector cavity, the two ends of the reflector cavity being a light inlet and a light outlet, and the side of the reflector plate facing away from the housing being a reflective surface; external light can enter the reflector cavity through the light inlet, be reflected by the reflective surface, and then exit through the light outlet.

[0009] In some embodiments of this application, the connecting portion includes two bending ribs, which are disposed on both sides of the plate body and extend along the length direction of the plate body; the bending ribs intersect with the plane of the plate body, and the bending ribs of adjacent reflectors can be connected to each other to realize the splicing and fixing of multiple reflectors.
[0010] In some embodiments of this application, the reflector cup further includes a locking member, and the bending rib is provided with a plurality of mutually spaced through holes; when the bending ribs of adjacent reflectors abut each other, the through holes on the reflectors are aligned with each other, and the locking member passes through the through holes of adjacent reflectors to fix the two adjacent reflectors.
[0011] In some embodiments of this application, the reflector further includes a pressure plate, and a pressure plate groove is provided at one end of the light outlet of the housing. The pressure plate is fixed in the pressure plate groove of the housing and abuts against the reflector cup in the housing cavity to fix the reflector cup in the housing.
[0012] In some embodiments of this application, the inner diameter of the housing cavity gradually increases along the direction of light emission; the width of the plate body gradually widens along the direction of light emission.

[0014] In some embodiments of this application, the reflector further includes a bayonet, which is connected to the end of the housing facing the light inlet and is used to engage with an external photographic light fixture.
[0015] This application also provides a photographic lighting system, including: a photographic lighting fixture, which includes a housing, a light source assembly disposed within the housing, and an accessory bayonet disposed on the housing; the light source assembly has a light mixing cavity, and the accessory bayonet has a light-transmitting hole, the light-transmitting hole being disposed opposite to the light source assembly; a reflector as described above, one end of the reflector being detachably connected to the accessory bayonet; light emitted by the light source assembly exits through the light-transmitting hole of the accessory bayonet and enters the reflector through the light-transmitting hole, is reflected by the reflective surface, and exits through the light-exiting hole.
[0016] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows:
[0017] This application provides a reflector and photographic light system, which includes a housing and a reflector cup disposed within the housing.

[0034] 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.
[0035] This paper addresses the technical problem that during the spinning process of traditional reflectors, the aluminum material undergoes plastic deformation under stress, making it difficult to maintain a high degree of smoothness on the inner wall surface, thus affecting reflectivity.
[0036] Please see Figures 1 to 10 This embodiment provides a reflector 100, which includes a housing 10 and a reflector cup 20 disposed within the housing 10.
[0037] The housing 10 has an internal cavity with openings at both ends. An outer reflector 20 is housed within this cavity. The reflector 20 includes multiple reflective plates 21 arranged circumferentially around the cavity. The sides of adjacent reflective plates 21 are connected and fixed to each other. The multiple reflective plates 21 are joined together to form a cylindrical reflective cavity 11. The two ends of the reflective cavity 11 are light inlets 12 and light outlets 13. The side of the reflector 21 facing away from the housing 10 is a reflective surface, used to reflect light entering the reflective cavity 11. Light enters the reflective cavity 11 through the light inlet 12 and exits through the light outlet 13 after reflection by the reflective surface.
[0038] Specifically, the housing 10 supports and protects the reflector cup 20. The housing 10 can be made of plastic, metal, or composite materials to meet different strength and weight requirements. The housing 10 can be formed using spinning or injection molding processes depending on the material. The housing 10 has an internal cavity with openings at both ends for mounting the reflector cup 20 and allowing light to pass through. The reflector cup 20 is located inside the housing 10 and is composed of multiple reflective plates 21. The sides of adjacent reflective plates 21 can be connected and fixed to each other, thus forming a cylindrical reflective cavity 11 structure. The two ends of the reflective cavity 11 have light inlets 12 and light outlets 13, which correspond to the openings at both ends of the housing 10. Using multiple reflective plates 21 to form the reflector cup 20 effectively improves the ease of manufacturing and assembly of the reflector cup 20 and reduces processing difficulty.
[0039] In particular, in some large reflectors 100, the reflector cup 20 is formed by splicing multiple reflectors 21 together. This not only does not damage the surface structure of the reflectors 21, but each reflector 21 can also be processed and surface-treated independently, ensuring high overall manufacturing precision. Moreover, users can adjust the number of spliced reflectors 21 according to different usage requirements to suit reflectors 100 of different sizes.
[0040] In some embodiments, thermally conductive silicone may be provided within the accommodating cavity of the housing 10. This silicone can be filled between the reflector 21 and the housing 10 to improve overall heat dissipation performance. This ensures that the reflector 100 can effectively reduce its temperature during prolonged operation, preventing performance degradation or damage due to overheating.
[0041] Please see Figure 4 , Figure 5 , Figure 9 and Figure 10 In some embodiments, the reflector 21 includes a plate body 211 and a connecting portion 212. The connecting portion 212 is disposed on both sides of the plate body 211 and extends along the length direction of the plate body 211. The connecting portions 212 of two adjacent reflectors 21 can be fixed to each other, so that adjacent reflectors 21 can be spliced together at a preset angle.
[0042] The length direction of the plate body 211 is the direction in which external light is emitted, that is, the direction of the line connecting the light inlet 12 and the light outlet 13. The connecting part 212 is provided on both sides of the plate body 211 and extends along the length direction of the plate body 211, so that adjacent two reflective plates 21 can be stably spliced.
[0043] In some embodiments, the connecting part 212 can be of various structures, such as snap-fit, tenon and mortise, bolt connection, magnetic connection, adhesive or welding, as long as it can enable adjacent reflectors 21 to be spliced together at a preset angle and finally enclosed to form a complete reflector cup 20 structure.
[0044] Please see Figure 5 In some embodiments, the connecting portion 212 includes a plurality of protrusions 2122 and grooves 2121. The protrusions 2122 and grooves 2121 are spaced apart along the side edge of the plate body 211, such that the protrusion 2122 of one reflector 21 can be embedded in the groove 2121 of another adjacent reflector 21, so as to realize the splicing and fixing of multiple reflectors 21.
[0045] Specifically, the protrusions 2122 and grooves 2121 on both sides of each reflector 21 are staggered and opposite, meaning that each side edge of a reflector 21 has protrusions 2122 and grooves 2121 spaced apart along its length, while the edges of adjacent reflectors 21 have corresponding grooves 2121 and protrusions 2122. When two reflectors 21 are spliced at a preset angle, the protrusions 2122 can be precisely embedded into the grooves 2121 of the adjacent reflectors 21. The protrusions 2122 and grooves 2121 are interference fits to prevent the reflectors 21 from loosening during splicing. After the reflectors 21 are assembled at a preset angle to form a complete reflector cup 20, the reflector cup 20 is glued to the inner wall of the receiving cavity of the housing 10, thus achieving the fixed installation of the reflector 100.
[0046] The use of protrusions 2122 and grooves 2121 in the splicing method makes the manufacturing of reflector 21 simpler. It only requires stamping grooves 2121 on both sides of the reflector 21, and protrusions 2122 are automatically formed between the two grooves 2121. The whole manufacturing process is simple and convenient, which can effectively improve the manufacturing efficiency of reflector cup 20.
[0047] Please see Figure 9 and Figure 10In some embodiments, the connecting portion 212 may include two bending ribs 2123. The two bending ribs 2123 are disposed on both sides of the plate body 211 and extend along the length direction of the plate body 211. The bending ribs 2123 intersect with the plane of the plate body 211, and the bending ribs 2123 of adjacent reflectors 21 can be connected to each other to realize the splicing and fixing of multiple reflectors 21.
[0048] Furthermore, the reflector cup 20 also includes a locking member 22, and the bending rib 2123 is provided with a plurality of mutually spaced through holes 2124. When the bending ribs 2123 of adjacent reflectors 21 abut against each other, the through holes 2124 on the reflectors 21 are aligned with each other, and the locking member 22 passes through the through holes 2124 of the adjacent reflectors 21 to fix the two adjacent reflectors 21.
[0049] Specifically, the reflector 21 is composed of a plate body 211 and a bending rib 2123 extending along its side edge. The bending rib 2123 is bent at a certain angle relative to the plane where the plate body 211 is located, that is, the bending rib 2123 is bent toward the side away from the reflective surface. The included angle between the bending rib 2123 and the plate body 211 can be determined according to the interior angle when the two reflectors 21 are spliced together.
[0050] The bending rib 2123 has multiple spaced through holes 2124. When the reflectors 21 are spliced together, the through holes 2124 on adjacent reflectors 21 are aligned to form a fixed channel through which the locking member 22 can pass. The locking member 22 passes through the fixed channel to fix the two reflectors 21, which can effectively prevent the reflectors 21 from loosening or shifting due to vibration or external force.
[0051] In some embodiments, the locking element 22 may be a screw, rivet, or pin. When the user aligns the bending ribs 2123 of adjacent reflectors 21, the through holes 2124 on the bending ribs 2123 correspond one-to-one. Then, the locking element 22 is inserted and tightened or engaged to firmly join the reflectors 21 together, forming a complete reflector cup 20.
[0052] The combination of bending ribs 2123 and locking components 22 makes the structure of the spliced reflector cup 20 more stable, effectively preventing misalignment between reflectors 21. It also improves the overall rigidity of the reflector cup 20, ensuring that its optical performance is not affected by deformation during long-term use, thus effectively enhancing the structural stability of the reflector 100.
[0053] It is conceivable that in some other embodiments, the fixing method of the bending rib 2123 can also be adjusted according to the usage scenario, for example, by welding, magnetic adsorption or other means to connect the bending ribs 2123 of adjacent reflectors 21 to each other.
[0054] Please see Figure 9In some embodiments, the reflector 100 further includes a pressure plate 40; a pressure plate groove 14 is provided at one end of the light outlet 13 of the housing 10. The pressure plate 40 is fixed in the pressure plate groove 14 of the housing 10 and abuts against the reflector cup 20 in the receiving cavity of the housing 10, thereby fixing the reflector cup 20 in the housing 10.
[0055] Specifically, one end of the light outlet 13 of the housing 10 is provided with a pressure plate groove 14. The pressure plate groove 14 is the embedding and positioning area of the pressure plate 40, so that the pressure plate 40 can form a stable connection with the housing 10. The pressure plate 40 is installed in the pressure plate groove 14 and abuts against the reflector cup 20 in the accommodating cavity, thereby applying a fixing force to the reflector cup 20, making it tightly attached to the inside of the housing 10, and preventing the reflector cup 20 from shaking or falling off during use.
[0056] During installation, the reflector cup 20 is first assembled from multiple reflectors 21 to form a complete cup-shaped structure, which is then placed within the receiving cavity of the housing 10. Subsequently, the pressure plate 40 is inserted into the pressure plate groove 14 along the light outlet 13 of the housing 10 and abuts against the reflector cup 20 to apply pressure to it. This ensures that the reflector cup 20 is firmly attached to the inside of the housing 10, thus achieving a fixed installation between the reflector cup 20 and the housing 10.
[0057] When the reflector cup 20 needs to be replaced, simply remove the pressure plate 40 from the housing 10 to remove the reflector cup 20 from the housing 10. The entire disassembly and assembly process is simple and convenient, allowing users to maintain or replace the reflector cup 20 at any time.
[0058] Of course, in some other embodiments, the reflector 21 can also be directly fixed to the inner wall of the accommodating cavity of the housing 10 by adhesive to form a reflector cup 20.
[0059] Please see Figures 1 to 9 In some embodiments, the panel body 211 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 housing 10 to form a reflective surface; the protective layer covers the reflective layer to protect it.
[0060] Specifically, the substrate layer can be made of aluminum alloy, which serves as the main structure of the reflector 21, providing necessary support to ensure its stable shape. The reflective layer is located on the side of the substrate layer facing away from the housing 10. 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. This reflective layer effectively improves light reflection efficiency, reduces light loss, and ensures that the light entering the reflector cup 20 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.
[0061] Through the multi-layered composite structure design of the substrate layer, reflective layer, and protective layer, the reflector 21 can achieve high reflectivity and durability. It is suitable for various environments and can be widely used in different types of reflectors 100, improving the overall reliability of the reflector 100.
[0062] 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.
[0063] 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 projection equipment with high brightness lighting or precision optical equipment.
[0064] In this embodiment, the reflector cup 20 is formed by splicing together multiple reflectors 21. Each sheet-like reflector 21 can be coated individually, thereby ensuring the uniformity of the coating. This further improves the reflection efficiency of the reflector cup 20, minimizes the energy loss of light after reflection, effectively enhances the output brightness of the light source, and meets the needs of high-precision lighting equipment.
[0065] Please see Figure 3 and Figure 8 In some embodiments, the inner diameter of the accommodating cavity of the housing 10 gradually increases along the direction of light emission; the width of the plate body 211 gradually widens along the direction of light emission.
[0066] In this design, the cavity of the housing 10 serves as a channel for light propagation, and its inner diameter gradually increases along the direction of light emission, causing the optical path space inside the housing 10 to transition from narrow to wide; that is, the cavity of the housing 10 has a gradually expanding structure. Simultaneously, the width of the plate body 211 gradually increases along the direction of light emission, specifically the width of the plate body 211 facing the light outlet 13. This ensures that the reflector cup 20 formed by the multiple reflectors 21 also has a gradually expanding structure, allowing it to fit the cavity and improve the installation stability of the reflector cup 20. The gradually expanding reflector cup 20 allows for sufficient reflection and focusing of light during propagation.
[0067] Please see Figure 3 and Figure 8 In some embodiments, the sidewalls inside the accommodating cavity of the housing 10 can be set as arc surfaces. In this case, the reflector 21 also has a certain curvature. The reflector 21 is arched along the length direction to form an arc-shaped reflective surface, so as to further adjust the angle of the light emitted from the light outlet 13.
[0068] Of course, in some other embodiments, the reflector 21 may also be a flat plate, and the inner wall of the accommodating cavity in the housing 10 may also be flat, in order to adapt to different light-gathering requirements.
[0069] Please see Figure 1 and Figure 6 In some embodiments, the reflector 100 further includes a bayonet 30. The bayonet 30 is connected to the end of the housing 10 facing the light inlet 12 and is used to engage with an external photographic light fixture 200.
[0070] The bayonet 30 includes a retaining ring 31 and a limiting block 32. The retaining ring 31 is fixed on the end face of the housing 10 facing the light inlet 12, and the limiting block 32 is disposed on the outer side wall of the retaining ring 31. The limiting block 32 can be embedded into the slot of the photographic light fixture 200, so that the reflector 100 can be quickly fixed to the photographic light fixture 200.
[0071] In some embodiments, such as Figure 9 As shown, the retaining ring 31 can be detachably connected to the housing 10 to allow for replacement according to the interface specifications of different photographic lights 200, thereby improving compatibility and adaptability. Specifically, the retaining ring 31 can be connected to the housing 10 using threaded connections, snap-fit connections, or other methods, allowing users to easily replace the compatible bayonet 30.
[0072] Of course, in some embodiments, such as Figure 4 As shown, the bayonet 30 can also be integrally formed with the housing 10 to reduce the number of components and improve the overall structural strength, which is suitable for specific models of photographic lighting fixtures 200 and ensures a more stable connection.
[0073] Please see Figure 11 This embodiment also provides a photographic lighting system, which includes a photographic light fixture 200 and a reflector 100 as described above.
[0074] The photographic lighting fixture 200 includes a housing 201, a light source assembly 205 disposed within the housing 201, and an accessory slot 202 disposed on the housing 201. The light source assembly 205 has a light mixing cavity 2052; the accessory slot 202 has a light-transmitting hole, which is positioned opposite to the light source assembly 205. One end of the light inlet 12 of the reflector 100 is detachably connected to the accessory slot 202, allowing light emitted from the light source assembly 205 to exit through the light-transmitting hole of the accessory slot 202, enter the reflector 100 through the light inlet 12, and exit through the light outlet 13 after reflection by the reflective surface.
[0075] Specifically, the outer shell 201 of the photographic lighting fixture 200 encloses its internal structure and provides physical support. The bottom surface of the outer shell 201 is equipped with support feet 204, allowing it to be stably placed on the ground. The top surface of the outer shell 201 is equipped with a handle 203 for easy carrying and movement. Support frames 206 are also connected to both sides of the outer shell 201. These support frames 206 are U-shaped and provide mounting points for the photographic lighting fixture 200, enabling it to be mounted on tripods, hanging devices, or other auxiliary support devices, thereby expanding its application scenarios.
[0076] The light source assembly 205 is disposed inside the housing 201. The light source assembly 205 can be an LED lamp, a xenon lamp, or other light source, capable of producing stable and high-intensity illumination. An accessory bayonet 202 is located on the housing 201. The accessory bayonet 202 can connect to different optical accessories, such as the reflector 100, diffuser, or other accessories in this embodiment. The accessory bayonet 202 has a light-transmitting hole, allowing light emitted from the light source assembly 205 to pass smoothly through the light-transmitting hole, exit the housing 201, and enter the connected optical accessory.
[0077] Please see Figure 12 In one example, the light source assembly 205 includes a lamp panel 2050 and a light shaping component 2051. The lamp panel 2050 integrates multiple light-emitting chips. The light shaping component 2051 is disposed within the housing 201 of the photographic lighting fixture 200 and above the lamp panel 2050. The light shaping component 2051 forms a mixing cavity 2052. Light emitted from the multiple light-emitting chips is mixed in the mixing cavity 2052 and then emitted towards the outside of the photographic lighting fixture 200. A light source lens 2053 can be further disposed on the light-emitting side of the mixing cavity 2052. The mixing cavity 2052 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.
[0078] In some examples, the light shaping component 2051 built into the photographic light 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 light 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.
[0079] In some embodiments, the accessory bayonet 202 is provided with a mating groove corresponding to the retaining ring 31 of the bayonet 30. The size of the mating groove matches the size of the retaining ring 31, so that the retaining ring 31 can be accommodated in the mating groove on the accessory bayonet 202. Multiple limiting grooves are provided on the side wall of the mating groove, and the limiting block 32 can be rotated into the limiting groove to fix the reflector 100 and the photographic light fixture 200.
[0080] When the light emitted by the light source assembly 205 passes through the light-transmitting hole of the accessory bayonet 202, the light enters the interior of the reflector 100 from the light inlet 12, is reflected on the reflective surface inside the reflector 100, and finally exits from the light outlet 13, thus achieving uniform guidance or enhancement of the light.
[0081] In summary, this application provides a reflector 100 and a photographic light system. The reflector 100 includes a housing 10 and a reflector cup 20 disposed within the housing 10. The housing 10 has an accommodating cavity with openings at both ends. The reflector cup is housed within the accommodating cavity. The reflector cup 20 is formed by splicing multiple reflector plates 21 together. Compared with the traditional integrally spun aluminum reflector cup 20, the spliced reflector cup 20 does not require surface spinning, and the reflector plates 21 will not be damaged due to shape processing. It can overcome the limitations of material processing, greatly improve the reflectivity of the reflective surface, and thus improve the overall brightness.
[0082] 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.
