Description

Technical Field

[0001] This utility model relates to the field of photographic and video equipment technology, and in particular to a reflector. 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 typically use a spinning process to manufacture the internal aluminum reflective cup. High-speed spinning causes the aluminum sheet to gradually deform along a mold, ultimately forming a cup-shaped structure with a smooth inner wall. However, during the spinning process, the aluminum undergoes plastic deformation under stress, affecting its surface microstructure and 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 improvements are not possible.

[0004] To improve reflection efficiency, some solutions employ a modular reflector structure, consisting of multiple coated or mirror-finished reflectors combined to form a cylindrical reflector. This type of structure typically involves fixing several reflectors circumferentially, each with an independent high-reflectivity surface, ideally forming a high-reflectivity reflective cavity. However, due to the unavoidable seams, corner joints, and assembly errors inherent in modular structures, practical use often results in discontinuous local reflections and inconsistent light deflection directions. This leads to uneven light output from the reflector, easily causing dark spots and unevenly concentrated bright areas, thus affecting the quality of the captured image. Utility Model Content

[0005] One objective of this invention is to solve the technical problem of low light output quality from 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; a reflector cup housed within the cavity; the reflector cup comprising multiple reflective plates arranged circumferentially around the cavity, with the sides of adjacent reflective plates abutting against each other, the multiple reflective plates being joined together to form a cylindrical reflective cavity, the two ends of the reflective cavity being a light inlet and a light outlet, respectively, and the side of the reflective plate facing away from the housing being a reflective surface; and a light-transmitting mirror disposed on the side of the housing facing the light outlet, the light-transmitting mirror covering the light emission path of the light outlet, used to perform light mixing processing on the light reflected by the reflective surface.

[0007] In some examples of this application, the reflector further includes a top cover, which is disposed on the light outlet side of the housing and fixedly connected to the housing; the top cover is provided with a light passage, and the light-transmitting mirror is fixedly disposed at the light passage of the top cover.

[0008] In some examples of this application, the top cover is an annular structure with a slot on its inner edge, and the light-transmitting lens is fixed in the slot.

[0009] In some examples of this application, the light-transmitting mirror protrudes outward along the side opposite to the housing to form a curved light-transmitting structure in the shape of a spherical crown.

[0010] In some examples of this application, the light-transmitting lens is made of glass, silicone, polycarbonate, or resin.

[0011] In some examples of this application, the reflector cup includes at least 16 reflector plates, each of which is an arc-shaped plate extending along its length, and each reflector plate has the same shape and thickness; the plurality of reflector plates can be arranged to rotate at equal angles around the central axis of the housing cavity, such that the adjacent boundaries of adjacent reflector plates fit together when spliced, so as to form a continuous reflective surface in the radial direction of the reflective surface of the reflector plates.

[0012] In some examples of this application, the reflector includes a plate body and a flanged portion, the flanged portion being disposed at one end of the plate body near the light inlet, and the flanged portion being folded outward along the radial direction of the plate body; the reflector also includes a pressure plate, the pressure plate being disposed on the light-inlet side of the housing, for uniformly pressing the flanged portions of the plurality of reflectors onto the end face of the housing.

[0013] In some examples of this application, the reflector further includes a bayonet connected to the end of the housing facing the light inlet, the bayonet being used to engage with an external photographic lighting fixture.

[0014] In some examples of this application, the bayonet is provided with a flange groove and a pressure plate groove on the end face away from the housing. The flange is accommodated in the flange groove of the bayonet, and the pressure plate is fixed in the pressure plate groove of the bayonet and abuts against the flange to press and fix the reflector.

[0015] In some examples of this application, the inner wall of the housing includes multiple mounting surfaces, which are arranged side by side along the circumference of the housing to form a receiving cavity; multiple reflectors are arranged in a one-to-one correspondence with the mounting surfaces on the housing, such that the side of the reflector facing away from the reflective surface is fixedly mounted to the corresponding mounting surface.

[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, comprising a housing and a reflector cup disposed within the housing. The housing has an internal cavity with openings at both ends, and the reflector cup is housed within the cavity. The reflector cup is formed by splicing together multiple reflective plates. A light-transmitting mirror is disposed on the light-exit side of the reflector, allowing light reflected from the reflective surfaces to be refracted or scattered again by the light-transmitting mirror before exiting the reflector. This effectively reduces uneven light spots and obvious light-dark boundaries caused by the reflector cavity formed by splicing multiple reflective plates. This achieves secondary homogenization of the emitted light, significantly improving the overall uniformity and smooth transition of the light spot, contributing to a softer and more uniform lighting effect, meeting the high light quality requirements of photography and film lighting, and effectively improving image quality.

[0028] Please see Figures 1 to 5 This embodiment provides a reflector 100, which includes a housing 10, a reflector cup 20, and a light-transmitting mirror 30.

[0029] The housing 10 has an internal cavity 11 with openings at both ends and a hollow interior. A reflector cup 20 is housed within the cavity 11. The reflector cup 20 includes multiple reflective plates 21 arranged circumferentially around the cavity 11. The sides of adjacent reflective plates 21 can abut against each other, and the multiple reflective plates 21 are joined together to form a cylindrical reflective cavity 201. The two ends of the reflective cavity 201 are a light inlet 202 and a light outlet 203, respectively. The side of the reflective plates 21 facing away from the housing 10 is a reflective surface. A light-transmitting mirror 30 is disposed on the side of the housing 10 facing the light outlet 203, covering the light emission path of the light outlet 203, and is used to mix the light reflected by the reflective surface.

[0030] Specifically, the housing 10 is used to support and protect 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 accommodating cavity 11 with openings at both ends for mounting the reflector cup 20 and allowing light to pass through.

[0031] The reflector cup 20 is disposed within the receiving cavity 11 of the housing 10 and is composed of multiple reflective plates 21. Each reflective plate 21 has a high reflectivity coating, with its reflective surface facing the inner cavity of the housing 10, effectively guiding light entering the reflective cavity 201 to the light outlet 203. Multiple reflective plates 21 are arranged circumferentially around the housing 10, with their sides abutting against each other, ultimately forming a cylindrical reflective cavity 201. Compared to the traditional integrally spun reflector cup 20, it is more flexible in manufacturing process, as it can replace the integral metal cup with independent reflective plates 21 with higher reflectivity, thereby improving light reflection efficiency.

[0032] A light-transmitting mirror 30 is provided on the side of the housing 10 facing the light outlet 203. This light-transmitting mirror 30 covers the light emission path of the light outlet 203 of the reflector 20. By effectively mixing the emitted light through the light-transmitting mirror 30, it disperses locally concentrated or deflected light, overcomes the problem of uneven light spots caused by the assembled reflector 20, and significantly improves the light quality performance. It is especially suitable for film and television and photography lighting applications that require high light uniformity.

[0033] Please see Figure 3 In some embodiments, the light-transmitting mirror 30 protrudes outward along the side opposite to the housing 10 to form a curved light-transmitting structure in the shape of a spherical crown.

[0034] Specifically, the spherical curved surface has superior refractive and diffusion characteristics compared to a flat surface, enabling it to uniformly spread light after reflection by the reflector cup 20, thereby forming a light spot with soft edges and uniform brightness distribution. This effectively avoids problems such as localized overexposure, dark spots, or obvious light and shadow boundaries caused by concentrated light. Furthermore, the curved lens 30 can withstand certain external impacts, especially during frequent disassembly, reassembly, handling, or lighting of the reflector 100. The convex curved surface of the lens 30 can utilize its curvature structure to form a force diffusion path, reducing the risk of damage caused by localized stress concentration. Of course, in other embodiments, the lens 30 can also be an asymmetric curved surface, cylindrical surface, or freeform surface to adapt to different light mixing effects.

[0035] In some embodiments, the light-transmitting lens 30 may be formed of glass, silicone, polycarbonate or resin material.

[0036] Specifically, the light-transmitting lens 30 can be made of different materials depending on the actual application scenario and performance requirements. For example, glass light-transmitting lenses 30 have excellent light transmittance and thermal stability, making them suitable for use in high-power lamps or in environments with prolonged high temperatures, and their surface is easy to coat. Silicone, on the other hand, has good flexibility and impact resistance, is not easily broken, and is especially suitable for use in outdoor environments or portable lamps; it also has a certain degree of UV resistance, is not prone to aging, and can extend the product's lifespan. Polycarbonate combines the advantages of high light transmittance, impact resistance, and lightweight, and has high molding efficiency and strong structural stability in injection molding. Resin materials can be modified as needed, such as by adding dispersants or scratch-resistant coatings, to further enhance their durability and optical performance.

[0037] In some embodiments, the inner or outer surface of the light-transmitting lens 30 may be treated with frosting, a coating layer, or an optical microstructure texture to further improve the light diffusion performance and meet the requirements of high-quality lighting effects for film and television shooting.

[0038] Please see Figures 3 to 5 In some embodiments, the reflector 100 further includes a top cover 40. The top cover 40 is disposed on one side of the light outlet 203 of the housing 10 and is fixedly connected to the housing 10. The top cover 40 is provided with a light passage 41, and a light-transmitting mirror 30 is fixedly disposed at the light passage 41 of the top cover 40.

[0039] Specifically, the top cover 40 has a light-passing opening 41 in the middle as a light emission channel, and the size of the light-passing opening 41 matches the reflector cup 20. The top cover 40 can be fixed to the end face of the light-exiting opening 203 of the housing 10, and the light-transmitting mirror 30 is pressed and fixed between the top cover 40 and the end face of the housing 10 to achieve the fixation between the light-transmitting mirror 30 and the housing 10. Using the top cover 40 to fix the light-transmitting mirror 30 to the housing 10 allows the light-transmitting mirror 30 to easily and quickly cover the light-exiting opening 203, improving the overall airtightness of the structure and preventing external impurities such as dust and moisture from entering the reflector cavity 201, affecting the optical effect or contaminating the mirror surface.

[0040] Of course, in some other embodiments, the light-transmitting lens 30 can also be directly fixed to the light outlet 203 side of the housing 10 by means of bonding, snap-fitting, etc.

[0041] Please see Figure 3 and Figure 5 In some embodiments, the top cover 40 is an annular structure with a slot 42 on its inner edge, and the light-transmitting mirror 30 is fixed in the slot 42.

[0042] Specifically, the top cover 40 has a ring-shaped structure with a slot 42 on its end face facing the housing 10. The slot 42 is typically an annular groove, the shape and size of which match the outer contour of the light-transmitting lens 30. During installation, the light-transmitting lens 30 enters the slot 42 along the axial direction of the top cover 40 and is fixed within the top cover 40 by the clamping action of the slot 42 in the radial direction. When the top cover 40 is fixed to the housing 10, the light-transmitting lens 30 can be placed over the light outlet 203 of the housing 10. The slot-type installation method requires no additional screws or adhesives, enabling convenient assembly and disassembly, facilitating subsequent maintenance or replacement of light-transmitting lenses 30 of different specifications, thereby improving the product's flexibility of use.

[0043] In some other embodiments, soft buffer elements such as silicone rings and shock-absorbing pads can be added to the inside of the slot 42 to further improve the shock absorption performance and avoid damage to the lens 30 caused by hard contact.

[0044] Please see Figure 4 and Figure 5 In some embodiments, the inner wall of the housing 10 includes a plurality of mounting surfaces 12. The plurality of mounting surfaces 12 are arranged side by side along the circumference of the housing 10 to form a receiving cavity 11. A plurality of reflectors 21 are arranged in a one-to-one correspondence with the mounting surfaces 12 on the housing 10, such that the side of the reflector 21 facing away from the reflective surface is fixedly mounted to the corresponding mounting surface 12.

[0045] Specifically, the inner wall of the housing 10 is not a continuous, smooth circular surface, but rather consists of multiple mounting surfaces 12 distributed circumferentially. These mounting surfaces 12 are arranged side-by-side in a ring, collectively forming a hollow accommodating cavity 11. Each mounting surface 12 is a relatively flat or slightly curved structural area, providing an independent and stable mounting base for the reflector 21. The reflector 21 is disposed inside the accommodating cavity 11, with its side facing away from the reflective surface corresponding one-to-one with the mounting surfaces 12 on the inner side of the housing 10. The reflector 21 can be fixed to the corresponding mounting surface 12 by adhesive, magnetic attraction, or snap-fit ​​connections, forming a stable structural connection.

[0046] In some embodiments, the reflector cup 20 includes at least 16 reflective plates 21. Each reflective plate 21 is an arc-shaped plate extending along its length, and each reflective plate 21 has the same shape and thickness. The multiple reflective plates 21 can be arranged at equal angles around the central axis of the receiving cavity 11 of the housing 10, such that the adjacent boundaries of adjacent reflective plates 21 fit together when spliced, and the reflective surface of the reflective plate 21 forms a continuous reflective surface in the radial direction.

[0047] Specifically, the number of mounting surfaces 12 and reflectors 21 in the housing 10 can be 16 or more. All mounting surfaces 12 and all reflectors 21 have the same curvature, allowing the reflectors 21 to be arranged in an equiangular rotational configuration around the central axis of the housing 10's accommodating cavity 11, thus forming an array structure around the same central axis in the circumferential direction. This allows the boundary lines between adjacent reflectors 21 to align naturally, effectively avoiding light leakage and uneven light refraction caused by obvious steps or gaps between the panels, and also forming a continuous annular reflective surface in the radial direction.

[0048] Furthermore, within the same diameter housing 10, the more reflective plates 21 the reflector cup 20 has, the more elongated reflective surfaces it possesses. These elongated reflective surfaces project a dense, interwoven distribution of light in space, resulting in more thorough light mixing at the light-transmitting mirror 30 and ultimately creating a more uniform illumination effect. Therefore, the number of reflective plates 21—18, 24, 32, 36, or more than 16 but less than 64—can be set according to different scene requirements to accommodate higher optical light mixing demands.

[0049] During assembly, each reflector 21 can be inserted sequentially from the opening of the housing 10, and its back side can be directly fixed to the mounting surface 12, thereby gradually constructing a complete and continuous cylindrical reflector cup 20 structure. Of course, in some other embodiments, the sides of the reflectors 21 can be spliced ​​together to form an integral reflector cup 20, and then the reflector cup 20 can be stored in the receiving cavity of the housing 10.

[0050] Please see Figures 3 to 5 In some embodiments, the reflector 100 further includes a fastening ring 50. The fastening ring 50 is disposed on the inner periphery of the reflector cup 20 formed by splicing multiple reflectors 21, and is used to press against the inner sidewall of the reflector cup 20 to tighten the seam between adjacent reflectors 21.

[0051] Specifically, the fitting ring 50 typically employs a closed-loop structure with a certain degree of elasticity or rigidity, such as a metal ring or a plastic reinforcing ring. The outer diameter of the fitting ring 50 is slightly larger than the inner diameter of the reassembled reflector cup 20. During installation, it is inserted into the inner cavity of the reflector cup 20 with external force, and expands outward in its radial direction, stably abutting against the inner surfaces of each reflector plate 21 to press and fix the reflector plate 21 onto the mounting surface 12 of the housing 10, thereby radially pressing the entire reflector cup 20. This effectively compresses the joint between adjacent reflector plates 21, reduces splicing gaps, prevents light leakage at gaps, and improves the overall optical path continuity and reflection uniformity. In addition, through the pressing action, the fitting ring 50 also enhances the overall structural stability of the reflector cup 20, preventing loosening, warping, or other deformation problems of the reflector plates 21 during transportation or use, and maintaining the good geometric shape of the reflector cup 20.

[0052] In some embodiments, the clamping ring 50 may also be designed as a polygonal ring structure corresponding to the number of reflectors 21, so that each side segment fits the shape of a single reflector 21 more closely, further enhancing the clamping effect.

[0053] Please see Figures 3 to 5 In some embodiments, the reflector 21 includes a plate body 211 and a flange 212. The flange 212 is disposed at one end of the plate body 211 near the light inlet 202, and the flange 212 is folded outward along the radial direction of the reflector cup 20. The reflector 100 also includes a pressure plate 60, which is disposed on the light-inlet side of the housing 10 and is used to uniformly press the flanges 212 of the plurality of reflectors 21 onto the end face of the housing 10.

[0054] The plate body 211 serves as the primary reflective carrier. The plate body 211 may include a substrate layer, a reflective layer, and a protective layer. The substrate layer can be made of aluminum alloy, which serves as the main structural element of the reflector 21, providing necessary support to maintain its stable shape. The reflective layer is located on the side of the substrate layer facing away from the housing 10. The 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.

[0055] The flanged portion 212 is located at one end of the plate body 211 near the light inlet 202 and folds outward radially, expanding outward in a ring shape. A pressure plate 60 is positioned on the side of the housing 10 near the light inlet 202; its cross-sectional shape can be circular or polygonal. The flanged portions 212 of multiple reflectors 21 are laid flat on the rear end face of the housing 10, and the pressure plate 60 applies axial force, pressing firmly against each flanged portion 212. Then, the pressure plate 60 is fixedly connected to the housing 10 using fastener screws, thereby firmly clamping each flanged portion 212 between them, achieving a stable connection between the reflectors 21 and the housing 10. This allows each reflector 21 to be uniformly fixed to the end of the housing 10 after assembly, further enhancing the overall tightness of the reflector cup 20.

[0056] Please see Figure 4 and Figure 5 In some embodiments, the reflector 100 further includes a bayonet 70. The bayonet 70 is connected to the end of the housing 10 facing the light inlet 202 and is used to engage with an external photographic lighting fixture.

[0057] The bayonet 70 may include a retaining ring 71 and a limiting block 72. The retaining ring 71 is fixed to the end face of the housing 10 facing the light inlet 202. The limiting block 72 is disposed on the outer wall of the retaining ring 71 and can be embedded into the groove of the photographic light fixture, so that the reflector 100 can be quickly fixed to the photographic light fixture.

[0058] In some embodiments, the retaining ring 71 can be detachably connected to the housing 10 to allow for replacement according to the interface specifications of different photographic lighting fixtures, thereby improving compatibility and adaptability. The retaining ring 71 can be connected to the housing 10 via threaded connection, snap-fit ​​connection, or other methods, allowing users to easily replace the compatible bayonet 70. Of course, in some embodiments, the bayonet 70 can also be integrally formed with the housing 10 to reduce the number of components and improve overall structural strength.

[0059] Please see Figure 4 and Figure 5 In some embodiments, the bayonet 70 has a flange groove 73 and a pressure plate groove 74 on the end face away from the housing 10. The flange 212 is accommodated in the flange groove 73 of the bayonet 70, and the pressure plate 60 is fixed in the pressure plate groove 74 of the bayonet 70 and abuts against the flange 212 to press and fix the reflector 21.

[0060] Specifically, multiple reflectors 21 are sequentially arranged in the receiving cavity 11 along the circumference of the housing 10, and the flange 212 of each reflector 21 is inserted into and fitted into the flange groove 73 of the bayonet 70. Subsequently, the pressure plate 60 is installed in the pressure plate groove 74 of the bayonet 70 and applies a clamping force to the flange 212 along the axial direction, thereby limiting and locking the flange 212 in the radial and axial directions, ensuring that the reflector 21 will not loosen or misalign during transportation, effectively improving the overall roundness and tightness of the reflector cup 20, and further improving the uniformity of light output and reflection efficiency.

[0061] Of course, in some other embodiments, the flange groove 73 can also be provided on the end face of the light inlet 202 side of the housing 10, and then directly abut against the flange portion 212 through the bayonet 70 which is detachably connected to the housing 10, thereby fixing the reflector 21.

[0062] In summary, this embodiment provides a reflector 100, which includes a housing 10 and a reflector cup 20 disposed within the housing 10. The housing 10 has an accommodating cavity 11 with openings at both ends. The reflector cup 20 is housed within the accommodating cavity 11 and is formed by splicing together multiple reflective plates 21. A light-transmitting mirror 30 is disposed on one side of the light outlet 203 of the reflector 100, so that the light reflected by the reflective surface is refracted or scattered again by the light-transmitting mirror 30 before being emitted. This effectively reduces the uneven light spots and obvious light-dark boundaries caused by the reflector cavity 201 formed by splicing multiple reflective plates 21, and achieves a second homogenization of the emitted light. This significantly improves the overall uniformity and smooth transition effect of the light spot, helps to obtain a softer and more uniform lighting effect, meets the high requirements for light quality in photography and film lighting, and effectively improves the image quality.

[0063] 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.
