[0033] Figure 1 A perspective view of the camera reflector in one direction is shown. Figure 2 A perspective view of the camera reflector in another direction is shown. Figure 3 A cross-sectional view of the camera reflector is shown. Figure 4 A perspective view of the ring-shaped pressing plate arranged at the end of the shell is shown. Figure 5 An exploded view of the camera reflector is shown. Figure 6 An exploded view of the camera reflector and the lamp body is shown. Figure 7 A cross-sectional view of the light source assembly is shown.

[0034] Referring to Figure 1 The embodiments of the present application provide a camera reflector 100, which can direct, focus, or dissipate the light emitted by the lamp body 200, optimize the light of the lamp body 200, and improve the lighting efficiency and functionality of the lamp body 200.

[0035] Referring to Figure 1 , Figure 2 and Figure 5 The camera reflector 100 can include a shell 110. The shell 110 is an open-ended hollow structure, and the shell 110 has an installation cavity 113 formed therein. The installation cavity 113 has an entrance 111 and an exit 112 at two ends, i.e., the light enters the installation cavity 113 from the entrance 111 and is emitted from the exit 112.

[0036] In some embodiments of the present application, the shell 110 can have only one layer of shell. The shell 110 with one layer of shell can be a lightweight plastic part formed by injection molding, hot forming, or 3D printing, which can reduce the weight of the camera reflector 100.

[0037] In other embodiments, the shell 110 with one layer of shell can also be a metal / alloy shell 110 formed by spinning, die casting, or other processes.

[0038] 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. The middle shell 110 can provide better support for the thin and easily deformable reflective sheet 120 described below.

[0039] In some embodiments of this application, see Figure 3 As shown, the housing 110 can adopt a shape similar to a gradually expanding horn. The diameter of the light outlet 112 is larger than the diameter of the light inlet 111, and the diameter of the mounting cavity 113 gradually increases in the axial direction of the housing 110, so that the light can expand the diffusion angle of the light within the housing 110.

[0040] In some embodiments of this application, see Figure 2 and Figure 6 As shown, the outer wall of the housing 110 near the light inlet 111 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 113 from the light inlet 111 of the housing 110.

[0041] 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.

[0042] 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.

[0043] In some embodiments of this application, see Figure 1 and Figure 5 As shown, the photographic reflector 100 also includes multiple reflective sheets 120. The multiple reflective sheets 120 can be produced using a non-spinning process, which avoids the generation of micro-wrinkles or scratches on the surface of the reflective sheets 120 by the spinning process, thereby ensuring that the reflective sheets 120 have a high reflectivity.

[0044] In some embodiments of the present application, the reflective sheet 120 comprises a substrate (not shown in the figure), a mirror surface reflection layer (not shown in the figure) and a protective layer (not shown in the figure) arranged on the substrate, the mirror surface reflection layer forms a reflection surface (not shown in the figure) away from the surface of the substrate, and the protective layer is arranged on the side of the mirror surface reflection layer away from the substrate to ensure that the reflection surface of the mirror surface reflection layer is not scratched and the reflection efficiency of the mirror surface reflection layer is ensured. The mirror surface reflection layer of the reflective sheet 120 is arranged on the side of the substrate away from the surface of the mounting cavity 113 to ensure that the light can be reflected at the mirror surface reflection layer and improve the light utilization rate.

[0045] For example, the reflective sheet 120 can adopt an aluminum sheet. The reflective sheet 120 adopting the aluminum sheet can not only reduce the weight of the photographic reflector 100, but also improve the reflectivity of the reflective sheet 120, thereby improving the lighting effect of the photographic lamp 10.

[0046] In some embodiments of the present application, a plurality of reflective sheets 120 can be arranged on the inner side wall of the mounting cavity 113 by splicing each other, so that the light entering the mounting cavity 113 through the light inlet 111 can be reflected on the reflection surface of the reflective sheet 120, thereby improving the light illumination range and improving the light intensity.

[0047] In some embodiments of the present application, as shown in Figure 5 The end of the reflective sheet 120 is respectively a wide edge end 121 and a narrow edge end 122. The narrow edge end 122 is arranged close to the light inlet 111, and the wide edge end 121 is arranged close to the light outlet 112. In the direction from the light inlet 111 to the light outlet 112, the width of the reflective sheet 120 gradually increases to form a reflective sheet 120 with a specific light outlet angle, thereby improving the light outlet effect of the light outlet 112.

[0048] In some embodiments of the present application, as shown in Figure 3 and Figure 5 In the direction from the light inlet 111 to the light outlet 112, the reflection surface is a curved surface, which is arranged to curve towards the shell 110 in the direction from the light inlet 111 to the light outlet 112, so that the light of the light inlet 111 can be reflected in the reflection cavity 123 and then emitted from the light outlet 112, thereby improving the light emission range.

[0049] In some embodiments of the present application, the mirror surface reflection layer of the reflective sheet 120 can be provided with scale armor and other microstructure units (not shown in the figure) for adjusting the light outlet angle. When the light is irradiated on the microstructure unit, it can be emitted in the required light outlet angle direction, so that the reflective sheet 120 can be applied to different scenes and increase the adaptability of the photographic reflector 100.

[0050] In some embodiments of the present application, as shown in Figure 1 and Figure 3As shown, the plurality of reflecting sheets 120 are spliced with each other in the mounting cavity 113, and a reflecting cavity 123 is formed between the plurality of reflecting sheets 120. In the direction from the light inlet 111 to the light outlet 112, the aperture of the reflecting cavity 123 gradually increases, so that the light at the light inlet 111 can be reflected in the reflecting cavity 123 and then emitted from the light outlet 112, thereby improving the light utilization and increasing the light intensity.

[0051] It can be understood that the plurality of reflecting sheets 120 adopt the same shape and parameters to ensure seamless splicing between adjacent reflecting sheets 120, thereby reducing the number of light beams directed to the inner side wall of the mounting cavity 113, reducing light loss, and ensuring the illumination intensity.

[0052] In some embodiments of the present application, referring to Figure 5 As shown, one end of the reflecting sheet 120 close to the light outlet 112 is provided with a flange 124, which is folded towards the outside of the reflecting cavity 123, i.e., the flange 124 is arranged outwardly from the center of the light outlet 112. The flange 124 is connected with the end of the shell 110 on the side of the light outlet 112, so that the reflecting sheet 120 formed by a non-spinning process can be connected with the end of the shell 110. The reflecting sheet 120 is connected with the end of the shell 110 through the flange 124, which can avoid the connection between the reflecting sheet 120 inside the mounting cavity 113 and the inner surface of the mounting cavity 113, avoid the slight deformation of the reflecting sheet 120 in the mounting cavity 113, and ensure the reflecting effect of the reflecting sheet 120.

[0053] In another embodiment of the present application, one end of the reflecting sheet 120 close to the light inlet 111 is provided with a flange 124 (not shown in the figure), which is folded towards the outside of the reflecting cavity 123, i.e., the flange 124 is arranged outwardly from the center of the light inlet 111. The flange 124 can be connected with the end of the shell 110 on the side of the light inlet 111, so as to avoid the slight deformation of the reflecting sheet 120 in the mounting cavity 113 and ensure the reflecting effect of the reflecting sheet 120.

[0054] In some embodiments of the present application, the reflecting sheet 120 close to the light inlet 111 is provided with a first flange 124 (not shown in the figure), and the reflecting sheet 120 close to the light outlet 112 is provided with a second flange 124 (not shown in the figure). The first flange 124 and the second flange 124 are both folded towards the outside of the reflecting cavity 123. The first flange 124 is connected with the end of the shell 110 on the side of the light inlet 111, and the second flange 124 can be connected with the end of the shell 110 on the side of the light outlet 112, so that the reflecting sheet 120 is connected with the shell 110. The opposite ends of the reflecting sheet 120 are connected with the shell 110 through the first flange 124 and the second flange 124, which can improve the stability of the reflecting sheet 120 in the mounting cavity 113 and avoid the falling of the reflecting sheet 120 to affect the reflecting effect.

[0055] It can be understood that the width of the turn-up 124 can be the same as the width of the wide edge end 121 of the reflecting sheet 120, and when the adjacent reflecting sheets 120 are spliced with each other, the adjacent turn-ups 124 are also spliced with each other to avoid exposing the mounting cavity 113 and ensure the reflecting effect of the reflecting cavity 123.

[0056] In addition, the turn-up 124 can be connected to the end of the shell 110 in a detachable manner such as screwing, bonding, clamping, etc.

[0057] The end of the shell 110 is provided with a plurality of first threaded holes 115 arranged at intervals in the circumferential direction thereof, and each turn-up 124 is provided with a second threaded hole 125 corresponding to the first threaded hole 115. The photographic reflector 100 further comprises a fixing member 130, which is arranged through the first threaded hole 115 and the second threaded hole 125 to fix the reflecting sheet 120 to the shell 110.

[0058] In some embodiments of the present application, as shown in Figure 5 The end of the shell 110 on the light outlet 112 side is provided with a plurality of first threaded holes 115 arranged at intervals in the circumferential direction thereof. Each turn-up 124 is provided with a second threaded hole 125 arranged therethrough, and when the reflecting sheet 120 is assembled in the mounting cavity 113, the second threaded hole 125 corresponds to the first threaded hole 115. The fixing member 130 can be a bolt or a screw, which is arranged through the second threaded hole 125 and the first threaded hole 115 in sequence and is threadedly connected with the first threaded hole 115 and the second threaded hole 125 to fix the reflecting sheet 120 to the shell 110, avoid the reflecting sheet 120 from falling off, ensure the stability of the reflecting sheet 120 in the mounting cavity 113, and further ensure the reflecting effect.

[0059] In another embodiment of the present application, the end of the shell 110 on the light inlet 111 side is provided with a plurality of first threaded holes 115 arranged at intervals in the circumferential direction thereof. The turn-up 124 is fixed to the end of the shell 110 on the side provided with the light inlet 111 by the fixing member 130.

[0060] In still another embodiment, the ends of the shell 110 on the light inlet 111 side and the light outlet 112 side are each provided with a plurality of first threaded holes 115, and the first turn-up 124 and the second turn-up 124 are each provided with a second threaded hole 125 corresponding to the first threaded hole 115. The first turn-up 124 is fixed to the end of the shell 110 on the side provided with the light inlet 111 by the fixing member 130, and the second turn-up 124 is fixed to the end of the shell 110 on the side provided with the light outlet 112 by the fixing member 130.

[0061] Referring to Figure 4As shown, the photographic reflector 100 further comprises a ring-shaped pressing plate 140, which is arranged on the side of the flange 124 away from the end of the shell 110. The ring-shaped pressing plate 140 can be connected to the flange 124 by means of bonding, screw connection or clamping, etc.

[0062] For example, referring to Figure 4 and Figure 5 As shown, the ring-shaped pressing plate 140 is provided with a plurality of third threaded holes 141, which are arranged in sequence and at intervals in the circumferential direction of the ring-shaped pressing plate 140. When the ring-shaped pressing plate 140 is arranged on the flange 124, the third threaded holes 141, the second threaded holes 125 and the first threaded holes 115 are located on the same axis. The fixing member 130 can pass through the third threaded holes 141, the second threaded holes 125 and the first threaded holes 115 in sequence and be screwed with the third threaded holes 141, the second threaded holes 125 and the first threaded holes 115, so as to connect the ring-shaped pressing plate 140, the reflecting sheet 120 and the shell 110. The stability of the reflecting sheet 120 in the mounting cavity 113 can be improved by the ring-shaped pressing plate 140, so as to avoid the generation of gaps due to the shaking of the reflecting sheet 120 and ensure the reflecting effect.

[0063] In some embodiments of the present application, the profile of the mounting cavity 113 is polygonal in the cross section perpendicular to the axial direction of the shell 110. The polygonal profile of the mounting cavity 113 enables the reflecting sheet 120 to be installed according to the polygonal profile of the mounting cavity 113, so as to facilitate the installation of the reflecting sheet 120 and reduce the production cost.

[0064] For example, the profile of the mounting cavity 113 is octagonal in the cross section perpendicular to the circumferential direction of the shell 110, i.e., the mounting cavity 113 is provided with eight mounting surfaces (not shown in the figure). The mounting cavity 113 is provided with eight reflecting sheets 120, which correspond to the eight mounting surfaces one by one. Each reflecting sheet 120 can be installed on each mounting surface.

[0065] In some embodiments of the present application, referring to Figure 1 and Figure 4 As shown, the inner edge profile of the ring-shaped pressing plate 140 coincides with the profile of the light outlet 112, i.e., the inner profile of the ring-shaped pressing plate 140 is the same as the profile of the light outlet 112. This avoids the blocking of the reflecting cavity 123 by the ring-shaped pressing plate 140, and further avoids the blocking of the light by the ring-shaped pressing plate 140, so as to ensure the amount of light emitted and the range of light emitted at the light outlet 112.

[0066] It should be noted that the reflecting sheet 120 and the surface of the mounting cavity 113 can also be bonded together, or a gap can be left therebetween.

[0067] In some embodiments of the present application, the reflective sheet 120 is bonded to the inner surface of the mounting cavity 113, i.e., each reflective sheet 120 is correspondingly arranged to match each mounting surface, so as to further ensure the stability of the reflective sheet 120 in the mounting cavity 113.

[0068] In some embodiments of the present application, the reflective sheet 120 has a gap with the surface of the mounting cavity 113. The photographic reflector 100 further comprises a heat-conducting member (not shown in the figure), which can be a heat-conducting tape, heat-conducting silicone grease or heat-conducting sheet, etc. The heat-conducting member can be arranged in the gap to conduct the heat in the reflective cavity 123 to the outside of the shell 110, so as to reduce the temperature in the reflective cavity 123.

[0069] In some embodiments of the present application, the outer side wall of the shell 110 is further provided with heat dissipation holes (not shown in the figure) for communicating the outside and the inside of the mounting cavity 113. A plurality of heat dissipation holes are arranged on the outer side wall of the shell 110. The heat dissipation holes can reduce the heat of the light irradiated on the reflecting surface of the reflective cavity 123, thereby reducing the overall heat of the photographic reflector 100 and avoiding overheating of the photographic reflector 100.

[0070] Referring to Figure 6 As shown in the figure, the present application further provides a photographic lamp 10, which comprises a lamp body 200 and the photographic reflector 100 described in the above embodiments. The lamp body 200 is detachably connected with the shell 110 of the photographic reflector 100.

[0071] For example, referring to Figure 6 As shown in the figure, the lamp body 200 is provided with a bayonet 210, and the outer side wall of the shell 110 near the light inlet 111 is provided with a buckle 114 in the circumferential direction. The buckle 114 on the shell 110 can be matched with the bayonet 210 on the lamp body 200, so that the shell 110 and the lamp body 200 are detachably connected through the buckle 114 and the bayonet 210.

[0072] In one example, referring to Figure 7As shown, the lamp body 200 includes a lamp shell and a light source assembly 220 located in the lamp shell, the light source assembly 220 includes a lamp plate 221 and a light shaping piece 222, the lamp plate 221 is integrated with a plurality of light emitting chips, the light shaping piece 222 is arranged in the shell of the lamp body 200 and above the lamp plate 221, the light shaping piece 222 is formed with a light source light mixing cavity 223, and the light emitted by the plurality of light emitting chips is mixed by the light source light mixing cavity 223 and then emitted to the outside of the lamp shell. A light source lens 224 can be further arranged on the light emitting side of the light source light mixing cavity 223. The light source light mixing cavity 223 built in the lamp body 200 can perform primary light shaping on the light emitting area, spot profile and / or light source light emitting angle of the light source, and perform secondary light shaping through the externally arranged and detachable photographic reflector 100, and different photographic reflector 100 with different angles or reflectivity is selected to achieve different lighting requirements for shooting.

[0073] In some examples, the light shaping piece 222 built in the lamp body 200 can be a light source reflector cup or a light source pressing block.
