Description

Technical Field

[0001] This application belongs to the field of lighting equipment technology, specifically relating to a photographic reflector and a photographic lighting fixture. Background Technology

[0002] Lighting fixtures generally consist of a photographic reflector and a lamp body; the lamp body has a light-emitting part to achieve the lighting effect; the photographic reflector is fixed to the lamp body to provide a focused light effect for the light-emitting part of the lamp body.

[0003] Currently, the reflector cups for photographic mirrors are typically manufactured using a spinning process. However, this process results in reflectors with low reflectivity, which fails to effectively and significantly improve illumination. To improve the reflectivity of photographic mirrors, some reflectors now use a non-spinning process to manufacture the reflector cups. However, this non-spinning process presents challenges in connecting and assembling the reflector cups with the mirror housing, leading to complex assembly issues. Utility Model Content

[0004] The purpose of this application is to solve the problems of complex connection and assembly between the reflector cup and the camera reflector housing manufactured by the non-spinning process in the prior art.

[0005] This application provides a photographic reflector, comprising: a housing with openings at both ends and a hollow interior, wherein a mounting cavity is formed inside the housing, and the two ends of the mounting cavity are a light inlet and a light outlet, respectively; at least two reflective rings, each disposed on the inner sidewall of the mounting cavity and arranged sequentially along the axis of the housing, wherein the surfaces of the at least two reflective rings away from the mounting cavity are reflective surfaces, and the reflective surfaces of the at least two reflective rings are joined to form a reflective cavity, wherein the diameter of the reflective cavity gradually increases in the direction from the light inlet to the light outlet, so that light at the light inlet can be reflected within the reflective cavity and emitted from the light outlet.

[0006] In one exemplary embodiment of this application, the reflective ring is an arc-shaped reflective sheet, which includes a plurality of reflective portions connected in sequence, with the reflective portion at the beginning connected to the reflective portion at the end to form an annular reflective ring.

[0007] In one exemplary embodiment of this application, the width of the reflective portion gradually increases in the direction from the light inlet to the light outlet.

[0008] In one exemplary embodiment of this application, the curvature of adjacent arc-shaped reflectors gradually increases in the direction from the light inlet to the light outlet.

[0009] In one exemplary embodiment of this application, in the direction from the light inlet to the light outlet, the reflective surfaces of the at least two reflectors are both arc surfaces, and the arc surfaces are curved toward the housing in the direction from the light inlet side to the light outlet side.

[0010] In an exemplary embodiment of this application, the inner wall of the mounting cavity is provided with a plurality of interlocking limiting surfaces in the circumferential direction. One end of the limiting surface is connected to the light inlet and the other end is connected to the light outlet. In the direction from the light inlet to the light outlet, the width of the limiting surface gradually increases.

[0011] In one exemplary embodiment of this application, the connection point of adjacent reflective portions coincides with the connection point of adjacent limiting surfaces.

[0012] In one exemplary embodiment of this application, the sum of the axial lengths of the at least two reflective rings is equal to the accommodating length of the inner wall of the mounting cavity.

[0013] In one exemplary embodiment of this application, the outer side wall of the housing near the light inlet is provided with a plurality of buckles, and the plurality of buckles are arranged sequentially at intervals in the circumferential direction of the housing.

[0014] A second aspect of this application provides a photographic lighting fixture, including a lamp body and a photographic reflector, wherein the lamp body includes a lamp housing and a light source assembly located within the lamp housing, the light source assembly includes a lamp panel and a light source mixing cavity located above the lamp panel, the photographic reflector is a photographic reflector according to any one of the preceding claims, the housing of the photographic reflector is connected to the lamp body, and the light emitted by the light source assembly enters the reflection cavity of the photographic reflector through the light source mixing cavity.

[0015] The photographic reflector and photographic lighting fixture proposed in this application have at least the following beneficial effects:

[0016] The at least two reflective rings in the photographic reflector of this application are manufactured using a non-spinning process, which avoids the micro-wrinkles or scratches that can occur on the surface of the reflective sheet when using a spinning process, thus ensuring that the reflective surface of the sheet has a high reflectivity. Furthermore, by sequentially arranging at least two reflective rings along the axis of the housing, problems such as poor fit between the reflective structure and the surface of the mounting cavity, and the tendency for micro-deformation of the mounting cavity surface, can be avoided when a long reflective structure is installed in the mounting cavity. By sequentially arranging at least two reflective rings within the housing mounting cavity, the fit between the reflective rings and the mounting cavity surface can be guaranteed, micro-deformation of the reflective rings and the mounting cavity surface can be reduced, and the difficulty of installing the reflective structure within the mounting cavity can be simplified, thereby reducing production costs.

Figure 10 A cross-sectional structural diagram of the light source assembly is shown.

[0037] This application provides a photographic reflector 100, which can directionally reflect, focus, or dissipate heat from the light emitted by the lamp body 200, optimize the light emitted by the lamp body 200, and improve the lighting efficiency and functionality of the lamp body 200.

[0038] Among them, see Figure 1 and Figure 2 As shown, the photographic reflector 100 may include a housing 110. The housing 110 is an open structure at both ends and hollow inside. A mounting cavity 111 is formed inside the housing 110. The two ends of the mounting cavity 111 are a light inlet 112 and a light outlet 113, respectively. That is, light enters the mounting cavity 111 from the light inlet 112 and then exits from the light outlet 113.

[0039] In some embodiments of this application, the housing 110 may have only one outer shell. The housing 110 with one outer shell may be made of lightweight plastic parts formed by injection molding, thermoforming or 3D printing, which can reduce the weight of the photographic reflector 100.

[0040] In other embodiments, the outer shell 110 can also be formed into a metal / alloy shell 110 by processes such as spinning or die casting.

[0041] In some embodiments, the housing 110 may also employ a double-layer shell, which may include a middle shell and an outer shell. The outer shell may be a hollow plastic or metal cup formed by processes such as stamping, spinning, or injection molding; the middle shell may be a metal hollow frame formed by spinning or die casting, which is embedded in the outer shell, and the middle shell 110 can provide better support for the thin and easily deformable reflective sheet described below.

[0042] In some embodiments of this application, see Figure 3 As shown, the housing 110 can be shaped like a horn. The diameter of the light outlet 113 is larger than the diameter of the light inlet 112, and the diameter of the mounting cavity 111 gradually increases in the axial direction of the housing 110, so that the light can expand the diffusion angle within the housing 110.

[0043] In some embodiments of this application, see Figure 2 and Figure 9As shown, the outer wall of the housing 110 near the light inlet 112 is provided with a plurality of protruding buckles 114, which are spaced apart in the circumferential direction of the housing 110. The light-emitting side of the lamp body 200 in the photographic light fixture 10 is provided with a slot 210 that matches the buckles 114. The buckles 114 of the housing 110 can be engaged in the slot 210 so that the photographic reflector 100 is fixed to the light-emitting side of the lamp body 200, thereby ensuring that the light from the lamp body 200 enters the mounting cavity 111 from the light inlet 112 of the housing 110.

[0044] It is understandable that the housing 110 may have a bayonet 210, and the light-emitting side of the lamp body 200 may have a buckle 114. The lamp body 200 and the housing 110 may be detachably connected through the buckle 114 and the bayonet 210, so that the photographic reflector 100 may be fixed to the light-emitting side of the lamp body 200.

[0045] In addition, the camera reflector 100 and the lamp body 200 can also be connected in other detachable ways, such as threaded connection, adhesive connection, etc.

[0046] In some embodiments of this application, see Figure 4 and Figure 5 As shown, the photographic reflector 100 also includes three reflective rings 120 manufactured using a non-spinning process. Along the direction from the light inlet 112 to the light outlet 113, the three reflective rings 120 are designated as a first reflective ring 120a, a second reflective ring 120b, and a third reflective ring 120c. All three reflective rings 120 are located on the inner wall of the mounting cavity 111 and are arranged sequentially along the axis of the housing 110, i.e., the three reflective rings 120 are coaxially arranged and sequentially spliced ​​within the mounting cavity 111. The surfaces of the three reflective rings 120 furthest from the mounting cavity 111 are all reflective surfaces. The reflective surfaces of the three reflective rings 120 are spliced ​​together to form a reflective cavity 121. Light entering the reflective cavity 121 can be reflected on this reflective surface, thereby increasing the amount of light emitted at the light outlet 113 and thus improving the illumination effect.

[0047] Understandably, the reflective ring 120 manufactured using a non-spinning process can avoid the generation of tiny wrinkles or scratches on the surface of the reflective ring 120 by the spinning process, thereby ensuring the integrity of the reflective surface of the reflective ring 120 and thus ensuring that the reflective surface has a high reflectivity.

[0048] In other embodiments of this application, the photographic reflector 100 further includes two reflective rings 120 manufactured using a non-spinning process, the two reflective rings 120 being sequentially spliced ​​together along the axial direction of the housing 110. The reflective surfaces of the two reflective rings 120 form the reflective cavity 121, within which light is reflected to increase the amount of light at the light outlet 113.

[0049] In other embodiments, the photographic reflector 100 further includes four reflective rings 120 made using a non-spinning process. The four reflective rings 120 are sequentially spliced ​​together in the axial direction of the housing 110, and the reflective surfaces of the four reflective rings 120 form the reflective cavity 121. Light is reflected in the reflective cavity 121 to increase the amount of light at the light outlet 113.

[0050] It is understandable that by sequentially arranging at least two reflective rings 120 along the axis of the housing 110, problems such as poor fit between the reflective structure and the surface of the mounting cavity 111 when a long reflective structure is installed in the mounting cavity 111 can be avoided, as well as the problem of slight deformation of the surface of the mounting cavity 111. By sequentially arranging at least two reflective rings 120 in the mounting cavity 111 of the housing 110, the fit between the reflective rings 120 and the surface of the mounting cavity 111 can be guaranteed, and the problem of slight deformation of the reflective rings 120 and the surface of the mounting cavity 111 can be reduced. At the same time, the difficulty of installing the reflective structure in the mounting cavity 111 can be reduced, and the production cost can be lowered.

[0051] In some embodiments of this application, see Figure 3 As shown, the diameter of the reflective cavity 121 gradually increases in the direction from the light inlet 112 to the light outlet 113, so that the light at the light inlet 112 can be reflected in the reflective cavity 121 and then emitted from the light outlet 113, thereby improving the light utilization rate and increasing the light intensity.

[0052] In some embodiments of this application, see Figures 6 to 8 As shown, the reflective ring 120 is an arc-shaped reflective sheet, with its two ends connected to form an annular reflective ring 120. The arc-shaped reflective sheet includes multiple sequentially connected reflective portions 122, with the first and last reflective portions 122 connected to form the annular reflective ring 120. The use of an arc-shaped reflective sheet in the reflective ring 120 ensures that when the arc-shaped reflective sheet is fitted to the surface of the mounting cavity 111, one end of the arc-shaped reflective sheet has a movable position relative to the surface of the mounting cavity 111. This allows for adjustment of the position of the arc-shaped reflective sheet when it is installed on the surface of the mounting cavity 111, reducing the difficulty of fitting the arc-shaped reflective sheet to the surface of the mounting cavity 111. Furthermore, it avoids errors in fitting the reflective sheet to the surface of the mounting cavity 111, preventing minor deformations and thus ensuring the reflective effect of the reflective surface.

[0053] In some embodiments of this application, in the axial direction of the housing 110, the two opposite ends of the reflective portion 122 are a wide end (not shown in the figure) and a narrow end (not shown in the figure), respectively. The narrow end is disposed near the light inlet 112, and the wide end is disposed near the light outlet 113. In the direction from the light inlet 112 to the light outlet 113, the width of the reflective portion 122 gradually increases to form a reflective ring 120 with a specific light emission angle, thereby improving the light emission effect of the light outlet 113.

[0054] In some embodiments of this application, the reflective ring 120 includes a substrate (not shown in the figure), a specular reflective layer (not shown in the figure), and a protective layer (not shown in the figure) disposed on the substrate. The surface of the specular reflective layer away from the substrate forms a reflective surface (not shown in the figure). The protective layer is disposed on the side of the specular reflective layer away from the substrate to ensure that the reflective surface of the specular reflective layer is not scratched and to ensure the reflection efficiency of the specular reflective layer. Specifically, the specular reflective layer of the reflective ring 120 is disposed on the side of the substrate away from the surface of the mounting cavity 111 to ensure that light can be reflected at the specular reflective layer, thereby improving light utilization.

[0055] For example, the reflector ring 120 can be made of aluminum sheet. Using aluminum sheet in the reflector ring 120 can not only reduce the weight of the photographic reflector 100, but also improve the reflectivity of the reflector, thereby improving the lighting effect of the photographic light fixture 10.

[0056] In some embodiments of this application, the mirror reflective layer of the reflective ring 120 may be provided with microstructure units such as scales for adjusting the light emission angle (not shown in the figure). When light shines on the microstructure unit, it can be emitted in the direction of the required light emission angle, so that the reflective ring 120 can be applied to different scenarios and increase the adaptability of the photographic reflector 100.

[0057] In some embodiments of this application, see Figures 6 to 8 As shown, in the direction from the light inlet 112 to the light outlet 113, the curvature of adjacent arc-shaped reflectors gradually increases, so that the arc area of ​​the arc-shaped reflectors in the direction from the light inlet 112 to the light outlet 113 gradually increases. That is, in the direction from the light inlet 112 to the light outlet 113, the diameter of the reflective cavity 121 gradually increases. The light at the light inlet 112 can be reflected in the reflective cavity 121 and then emitted from the light outlet 113, thereby improving the light utilization rate and increasing the light intensity.

[0058] In some embodiments of this application, see Figure 3 As shown, in the direction from the light inlet 112 to the light outlet 113, the reflective surface is an arc surface. The arc surface is bent toward the housing 110 in the direction from the light inlet 112 to the light outlet 113, so that the light from the light inlet 112 can be reflected in the reflective cavity 121 and then emitted from the light outlet 113, thereby increasing the light emission range.

[0059] In some embodiments of this application, such as Figure 5 As shown, in a cross-section perpendicular to the axial direction of the housing 110, the mounting cavity 111 has a polygonal shape. The polygonal shape of the mounting cavity 111 allows the reflector to be installed according to its polygonal outline, making installation more convenient and reducing production costs.

[0060] For example, in a cross-section perpendicular to the circumference of the housing 110, the mounting cavity 111 has an octagonal shape, meaning that the mounting cavity 111 has eight limiting surfaces (not shown in the figure). The reflective ring 120 includes eight reflective parts 122, each corresponding to one of the eight limiting surfaces. Each reflective part 122 can be mounted on its respective limiting surface to prevent it from falling out of the mounting cavity 111 and to ensure the reflective effect of the reflective part 122.

[0061] It is understandable that the reflective parts 122 all adopt the same shape and parameters to ensure seamless splicing between adjacent reflective parts 122, thereby reducing the amount of light that hits the inner wall of the mounting cavity 111, reducing light loss, and ensuring light intensity.

[0062] In some embodiments of this application, see Figure 5 As shown, the connection point of adjacent reflective parts 122 coincides with the connection point of adjacent limiting surfaces, which can ensure the shaping of the arc-shaped reflective sheet in the mounting cavity 111, improve the fit between the arc-shaped reflective sheet and the mounting cavity 111, and reduce production costs.

[0063] In other embodiments of this application, the arc-shaped reflective sheet can be an integral structure, which can be formed with creases by processes such as hot pressing, rolling, laser bending, and water jet cutting. The creases coincide with the connection of the adjacent limiting surface to ensure the shaping of the arc-shaped reflective sheet in the mounting cavity 111.

[0064] In some embodiments of this application, such as Figure 3 As shown, the sum of the axial lengths of the three reflective rings 120 is equal to the accommodating length of the inner wall of the mounting cavity 111. That is, the reflective rings 120 completely cover the inner wall of the mounting cavity 111, ensuring that all light rays incident on the inner wall of the mounting cavity 111 can be reflected by the reflective cavity 121, thereby increasing the number of light rays emitted at the light outlet 113 and thus improving the light utilization rate.

[0065] In some embodiments of this application, the arc-shaped reflector and the limiting surface of the mounting cavity 111 can be directly bonded together to ensure the stability of the arc-shaped reflector within the mounting cavity 111.

[0066] In other embodiments of this application, a gap exists between the arc-shaped reflector and the limiting surface. The photographic reflector 100 also includes a heat-conducting element (not shown in the figure), which may be made of materials such as thermal pads, thermal grease, or thermal sheets. The heat-conducting element may be disposed within the gap to conduct heat from the reflective cavity 121 to the outside of the housing 110, thereby reducing the temperature inside the reflective cavity 121.

[0067] In some embodiments of this application, the outer wall of the housing 110 is also provided with heat dissipation holes (not shown in the figure) for connecting the outside world and the inside of the mounting cavity 111, and multiple heat dissipation holes are arranged at intervals on the outer wall of the housing 110. The heat dissipation holes can reduce the heat of light shining on the reflective surface of the reflective cavity 121, thereby reducing the overall heat of the photographic reflector 100 and preventing the photographic reflector 100 from overheating.

[0068] It is worth mentioning that the reflective ring 120 at the first and / or last end may be provided with a flange (not shown in the figure), which is connected to the end of the housing 110 to improve the connection stability between the reflective ring 120 and the housing 110.

[0069] For example, in the direction from the light inlet 112 to the light outlet 113, the mounting cavity 111 is provided with a first reflective ring 120a, a second reflective ring 120b, and a third reflective ring 120c, respectively. The first reflective ring 120a has a first flange (not shown in the figure) folded outwards towards the housing 110 at its end near the light inlet 112, and the first reflective ring 120a is connected to the end of the housing 110 with the light inlet 112 via the first flange. The third reflective ring 120c has a second flange (not shown in the figure) folded outwards towards the housing 110 at its end near the light outlet 113, and the third reflective ring 120c is connected to the end of the housing 110 with the light outlet 113 via the second flange. The first and second flanges improve the tightness of the connection between the first reflective ring 120a and the third reflective ring 120c and the housing 110.

[0070] See Figure 9 As shown, this application embodiment also provides a photographic lighting fixture 10, which includes a lamp body 200 and a photographic reflector 100 described in the above embodiment. The lamp body 200 and the housing 110 in the photographic reflector 100 are detachably connected.

[0071] For example, the lamp body 200 is provided with a bayonet 210, and the outer side wall of the housing 110 near the light inlet 112 is provided with a buckle 114. The buckle 114 on the housing 110 can cooperate with the bayonet 210 on the lamp body 200 so that the housing 110 and the lamp body 200 are detachably connected through the buckle 114 and the bayonet 210.

[0072] In one example, see Figure 9and Figure 10 As shown, the lamp body 200 includes a lamp housing and a light source assembly 220 located inside the lamp housing. The light source assembly 220 includes a lamp plate 221 and a light shaping component 222. The lamp plate 221 integrates multiple light-emitting chips. The light shaping component 222 is disposed inside the outer shell of the lamp body 200 and above the lamp plate 221. The light shaping component 222 forms a light source mixing cavity 223. The light emitted by the multiple light-emitting chips is mixed by the light source mixing cavity 223 and then emitted out of the lamp housing. A light source lens 224 can be further disposed on the light-emitting side of the light source mixing cavity 223. The light source mixing cavity 223 built into the lamp body 200 can perform primary light shaping on the light-emitting area, light spot outline, and / or light emission angle of the light source, and perform secondary light shaping through an externally detachable photographic reflector 100. Different lighting requirements for shooting can be achieved by selecting photographic reflectors 100 with different angles or reflectivities.

[0073] In some examples, the light-shaping component 222 built into the lamp body 200 can be a light source reflector or a light source clamping block, etc.

[0074] In some examples of this application, the light shaping of the lamp body 200 by the photographic reflector 100 includes the adjustment of the light emission angle. For example, different photographic reflectors 100 can achieve various light emission angle adjustments such as 25 degrees, 30 degrees, 45 degrees, 50 degrees, 60 degrees, and 75 degrees.
