DETAILED DESCRIPTION

[0036] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can have various changes in different embodiments, which do not deviate from the scope of the present application, and the description and drawings in essence are used for description, not for limiting the present application.

[0037] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indication of direction or position relationship (such as up, down, left, right, front and back, etc.) is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. When the position of these elements is changed, the indication of these directions is also changed accordingly.

[0038] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0039] The present application provides a reflector 10, which has high reflectivity, so that the reflector 10 provided by the present application effectively improves the illuminance of the light compared with the reflector 10 made by the spinning process in the prior art. The specific scheme is illustrated by the following embodiments.

[0040] Please refer to Figure 1 and Figure 2The light reflector 10 comprises a shell 11 and a mirror surface 12.

[0041] The mirror surface 12 is arranged inside the shell 11. The shell 11 is configured to be connected with a light emitting lamp 20, so that light can enter the inside of the shell 11, and part of the light is processed by the mirror surface 12 and is emitted to the outside of the shell 11.

[0042] Specifically, the shell 11 is open at both ends and hollow inside. The opposite ends of the shell 11 are a small-diameter end 111 and a large-diameter end 112, respectively. The opening diameter of the small-diameter end 111 is smaller than that of the large-diameter end 112. The small-diameter end 111 of the shell 11 is connected with the light emitting lamp 20. Therefore, light enters the inside of the shell 11 from the small-diameter end 111 of the shell 11, and is emitted to the outside of the light reflector 10 through the large-diameter end 112.

[0043] It should be noted that the shell 11 can be a plastic shell 11, which is made by injection molding, thermoforming, 3D printing, etc. The plastic shell 11 makes the shell 11 lighter in weight, so that the light reflector 10 is overall lighter and is convenient for users to carry. Alternatively, the shell 11 can also be a metal shell 11 or an alloy shell 11, which is made by spinning, stamping, die casting, etc. The metal shell 11 or the alloy shell 11 makes the shell 11 stronger in strength, so that the light reflector 10 has better anti-deformation ability and can effectively protect the mirror surface 12 arranged inside.

[0044] Referring to Figure 3 The inside of the shell 11 is provided with a plurality of mounting surfaces 113, which enclose a receiving cavity 114.

[0045] Referring to Figure 4 and Figure 5 The mirror surface 12 is arranged in the receiving cavity 114 and is in contact with the mounting surfaces 113. The mounting surfaces 113 can effectively support the mirror surface 12 and prevent the mirror surface 12 from deforming.

[0046] Exemplarily, the mirror surface 12 can be mounted on the mounting surfaces 113 of the shell 11 by adhesion.

[0047] Referring to Figure 6 to Figure 8 Light can enter the inside of the shell 11 through the light inlet, and part of the light is incident to the mirror surface 12 and is emitted from the light outlet of the shell 11 after being reflected by the mirror surface 12. It can be understood that the mirror surface 12 is configured to control the direction of light, in particular, to reorient the light deviated from the light outlet so as to be emitted from the light outlet, thereby effectively improving the utilization rate of light.

[0048] Specifically, the mirror surface reflection plate 12 comprises a substrate (not shown in the figure) and a reflection layer (not shown in the figure) provided on the substrate, and the reflection layer is used for reflecting light. The reflection layer can be a silver layer, an aluminum layer or other high reflection layer, which can be set according to actual needs, and is not limited here. Taking the silver layer as an example, silver has very high reflectivity, and using high-purity silver as the reflection layer can make the reflectivity of the light shield 10 reach more than 92%.

[0049] In some embodiments, the mirror surface reflection plate 12 comprises a protective layer (not shown in the figure) provided on the surface of the reflection layer. That is, the protective layer covers the reflection layer to avoid oxidation or damage caused by bumps and scratches, which is beneficial to ensure the normal function of the reflection layer and help prolong the service life of the camera protection cover.

[0050] Referring to Figure 6 , the mirror surface reflection plate 12 is an integral structure. The mirror surface reflection plate 12 comprises a body 121 and a plurality of folds 122. The plurality of folds 122 are provided on the body 121 and divide the body 121 into a plurality of light reflecting bodies 123. The plurality of light reflecting bodies 123 are provided one by one on the plurality of mounting surfaces 113. Moreover, all the light reflecting bodies 123 enclose a light reflecting cavity 124. It can be understood that the reflection layer in the light reflecting body 123 is provided on the side surface away from the mounting surface 113.

[0051] Among them, the fold 122 can be a hot pressing line, a rolling line, a laser bending line or a water jet cutting line, etc. That is, the mirror surface reflection plate 12 can be processed by hot pressing process, rolling process, laser bending process or water jet cutting process, etc. to generate the corresponding fold 122.

[0052] The arrangement of the fold 122 enables the mirror surface reflection plate 12 in an integral structure to be bent so that the opposite two sides of the body 121 can be connected to each other to enclose the light reflecting cavity 124. Therefore, it can be understood that the outline of the light reflecting cavity 124 is related to the shape of the body 121 and the arrangement of the fold 122, which can be set according to actual needs.

[0053] In this embodiment, the fold 122 is provided with seven, thereby dividing the body 121 into eight light reflecting bodies 123. The eight light reflecting bodies 123 enclose a light reflecting cylinder. The number of the fold 122 can be set according to actual needs, as long as the body 121 can be bent along the fold 122 so that the opposite two sides of the body 121 can be connected to each other to enclose a light reflecting cavity 124.

[0054] Exemplarily, the plurality of folds 122 divide the body 121 into a plurality of reflectors 123 of the same shape and size. In other embodiments, the plurality of folds 122 can also divide the body 121 into a plurality of reflectors 123 of different shapes, which can be set according to actual needs, as long as the body 121 can enclose the light reflection cavity 124.

[0055] In addition, it should be noted that the shape and size of the mounting surface 113 are the same as those of the reflector 123, which ensures that each reflector 123 can be closely attached to the mounting surface 113 of the shell 11, helps to improve the fastening and stability of the mirror surface reflection plate 12 installed inside the shell 11, and can effectively ensure the profile of the formed light reflection cavity 124. In the present application, each mounting surface 113 extends from the small aperture end 111 to the large aperture end 112. Therefore, the reflector 123 mounted on the mounting surface 113 also extends from the small aperture end to the large aperture end 112.

[0056] Specifically, in the present embodiment, each reflector 123 has a trapezoidal structure. Specifically, the opposite sides of the reflector 123 are a shorter side 123a and a longer side 123b, respectively. The width of the reflector 123 gradually increases in the direction from the shorter side 123a to the longer side 123b. The shorter side 123a is arranged close to the small aperture end 111, and the longer side 123b is arranged close to the large aperture end 112.

[0057] Referring to Figure 4 In some embodiments, the body 121 of the mirror surface reflection plate 12 is an arc-shaped plate. The folds 122 arranged on the body 121 are arc lines, and the reflectors 123 divided by the body 121 are also arc-shaped plates. With the axis of the light reflection cavity as the reference, the reflector 123 curves in the direction from the light reflection cavity 124 to the outer wall of the shell 11. At this time, the profile of the light reflection cavity 124 enclosed by the reflector 123 is approximately a circular truncated cone structure.

[0058] In another embodiment of the present application, the body 121 of the mirror surface reflection plate 12 can also be a planar plate. The folds 122 arranged on the body 121 are straight lines, and the reflectors 123 divided by the body 121 are also planar plates. At this time, the profile of the light reflection cavity 124 enclosed by the reflector 123 is approximately a prismatic truncated cone structure.

[0059] It can be understood that in the direction from the small aperture end 111 to the large aperture end 112, the light reflection cavity 124 has a gradually expanding shape, and the area of the cross section of the light reflection cavity 124 gradually increases. This setting can ensure uniform diffusion of light during reflection, avoiding excessive concentration of light or uneven shadows.

[0060] In some embodiments, the light-reflecting body 123 is provided with a plurality of light-adjusting microstructures (not shown in the figure) on the inner side surface thereof facing the light-reflecting cavity 124, which are used to adjust the light-emitting angle of the light. The light-adjusting microstructures are used to adjust the light-emitting angle of the light incident on the surface of the light-adjusting microstructures, so that the light is emitted from the light-emitting opening. The light-adjusting microstructures include a plurality of scales arranged in an array, for example, the scales are arranged in a rectangular, rhombic, honeycomb or irregular shape on the inner side surface of the light-reflecting body 123 facing the light-reflecting cavity 124. Alternatively, the light-adjusting microstructures include a plurality of scales arranged irregularly and different from each other. The scales are arranged to protrude from the surface of the body 121 or recessed in the surface of the body 121.

[0061] The light-adjusting microstructures can be directly arranged on the reflecting layer, or the light-adjusting microstructures are arranged on the body 121, and the reflecting layer is arranged on the light-adjusting microstructures. The light-adjusting microstructures and the reflecting layer work together to reduce light loss by using the reflecting layer, and to adjust the light-emitting angle of the light by using the light-adjusting microstructures, so as to effectively reduce the loss of light and make more light emitted from the large-diameter end 112 of the light-reflecting cover 10, thereby effectively improving the illuminance of the film and television lamp 20.

[0062] Referring to Figure 5 In some embodiments, the light-reflecting cover 10 includes a heat-conducting layer 13, and the opposite side surfaces of the heat-conducting layer 13 are respectively connected to the surface of the mounting surface 113 of the shell 11 and the outer side surface of the body 121 away from the light-reflecting cavity 124. The arrangement of the heat-conducting layer 13 can effectively improve the heat dissipation performance of the light-reflecting cover 10, so that the heat on the mirror surface reflecting plate 12 is transferred to the shell 11 and then dissipated to the outside of the shell 11. The heat-conducting layer 13 can be a heat-conducting silica gel or the like.

[0063] Referring to Figure 8 The light-reflecting cover 10 includes a connecting structure 14 arranged on the small-diameter end 111 of the shell 11, and the connecting structure 14 is used to connect the film and television lamp 20.

[0064] In this embodiment, the connecting structure 14 includes a plurality of clamping portions 141, which are arranged on the outer peripheral wall of the shell 11 and are arranged along the circumference of the shell 11.

[0065] Referring to Figure 9 The application further provides a lighting system 100, which includes the film and television lamp 20 and the light-reflecting cover 10 as described above. The film and television lamp 20 can emit light.

[0066] Specifically, the film and television lamp 20 comprises a shell 24. The shell 24 is provided with a light exit window 21 through which the light emitted by the film and television lamp 20 is emitted to the outside. A bayonet structure 22 is arranged on the periphery of the light exit window 21 so that the light exit window 21 can be aligned with the small-diameter end 111 of the reflector 10, so that as many light rays as possible emitted by the film and television lamp 20 enter the inside of the reflector 10.

[0067] Referring to Figure 10 , the film and television lamp 20 comprises a light source assembly 25. The light source assembly 25 is arranged inside the lamp shell and is used to emit light. Specifically, the light source assembly 25 comprises a lamp panel 251 and a light source mixing cavity 252. The light source mixing cavity 252 is located between the lamp panel 251 and the light exit window 21. The light emitted by the lamp panel 251 enters the light mixing cavity 124 of the reflector through the light source mixing cavity 252 and the light exit window 21.

[0068] Further, the light source assembly 25 is arranged below the light exit window 21 and inside the shell 24 of the film and television lamp 20. The light emitted by the light source assembly 25 after being powered on is reflected to the outside of the film and television lamp 20 through the light exit window 21.

[0069] In one embodiment, the light source assembly 25 comprises a lamp panel 251 and a light shaping member 253, the lamp panel 251 is integrated with a plurality of light emitting chips, the light shaping member 253 is arranged inside the shell 24 of the film and television lamp 20 and above the lamp panel 251, the light shaping member 253 forms a light source mixing cavity 252, and the light emitted by the plurality of light emitting chips is emitted to the outside of the film and television lamp 20 after being mixed by the light source mixing cavity 252.

[0070] In some embodiments, a light source lens 254 can be further arranged on the side of the light source mixing cavity 252 away from the lamp panel 251, the light source lens 254 can serve as the light exit window 21, thereby forming the light source mixing cavity 252 between the lamp panel 251 and the light exit window 21, and the light emitted by the plurality of light emitting chips is emitted to the outside of the film and television lamp 20 after being mixed by the light source mixing cavity 252 and then through the light exit window 21. When the film and television lamp 20 is attached with the reflector 10, the light emitted from the light exit window 21 enters the reflector 10 and is then irradiated to the shooting target.

[0071] The light source mixing cavity 252 built-in the film and television lamp 20 can perform primary light shaping on the light emitting area, spot profile and / or light emitting angle of the light source, and perform secondary light shaping through the externally arranged and detachable reflector 10, thereby realizing different lighting requirements for different shooting by selecting reflectors 10 with different angles or reflectivities.

[0072] In some embodiments, the light shaping member 253 built-in the film and television lamp 20 can be a light source reflector cup or a light source pressing block structure, etc. In some embodiments of the present application, the light shaping of the film and television lamp 20 by the reflector hood 10 includes adjustment of the light emitting angle, for example, different reflector hoods can realize adjustment of multiple light emitting angles such as 25 degrees, 30 degrees, 45 degrees, 50 degrees, 60 degrees, 75 degrees, etc.

[0073] The film and television lamp 20 is provided with a bayonet structure 22 matched with the connecting structure 14 in the reflector hood 10, so that the reflector hood 10 and the film and television lamp 20 can be detachably connected.

[0074] For example, the bayonet structure 22 includes multiple limiting blocks 221, which are arranged at intervals, and the distance between adjacent limiting blocks 221 can be provided for the clamping part 141 to pass through. After the clamping part 141 passes through the gap between the adjacent two limiting blocks 221, the shell 11 is rotated, so that the clamping part 141 abuts against the limiting block 221, thereby realizing the clamping installation of the reflector hood 10 on the film and television lamp 20.

[0075] Among them, the number of limiting blocks 221 corresponds to the number of clamping parts 141, for example, in this embodiment, the clamping part 141 and the limiting block 221 are each provided with three, which can be set according to actual needs, and is not limited here.

[0076] See Figure 11 In some embodiments, the side of the limiting block 221 close to the light emitting window 21 is provided with a limiting gap 222, and the clamping part 141 can be accommodated in the limiting gap 222. The limiting gap 222 can avoid excessive rotation of the reflector hood 10, thereby ensuring the secure installation of the reflector hood 10 on the film and television lamp 20.

[0077] It should be noted that in addition to the above connecting mode of the reflector hood 10 clamped on the film and television lamp 20, the detachable connection between the reflector hood 10 and the film and television lamp 20 can also be screwing, plugging, etc. For example, the connecting structure 14 in the reflector hood 10 can be a threaded structure, and the bayonet structure 22 on the film and television lamp 20 can be a screw structure matched therewith, so that the reflector hood 10 can be screwed on the film and television lamp 20; or the connecting structure 14 in the reflector hood 10 can be a plug-in structure, and the bayonet structure 22 on the film and television lamp 20 can be a slot structure matched therewith, so that the reflector hood 10 can be plugged on the film and television lamp 20, etc.

[0078] See Figure 11In addition, the setting of the bayonet structure 22 on the film and television lamp 20 also enables the film and television lamp 20 to be connected with other light effect accessories, thereby enriching the light effect of the film and television lamp 20. The other light effect accessories can be a soft light box, a Fresnel lens, etc. In some embodiments, the film and television lamp 20 includes a conductive end 23. The film and television lamp 20 can be electrically connected with the light effect accessories through the conductive end 23, thereby being able to supply power to the optical accessories and realize the control of the external optical accessories. The reflector 10 in the present application can be provided with a relief groove that avoids the conductive end 23, so as to protect the conductive end 23 of the film and television lamp 20.

[0079] Alternatively, the reflector 10 in the present application includes a circuit board (not shown in the figure) and an electrical connection end 15, and the circuit board is electrically connected with the electrical connection end 15. The electrical connection end 15 is used to be electrically connected with the conductive end 23, so as to form the electrical connection between the reflector 10 and the film and television lamp 20.

[0080] The circuit board can include a temperature sensor, a module for detecting the installation position feedback, etc., which is used to feed back the information such as the installation position of the reflector or the temperature of the reflector to the film and television lamp 20 or the controller or application software that is electrically connected with the film and television lamp 20, so as to enable the user to timely understand or check the state of the reflector 10, and effectively improve the user experience.

[0081] See Figure 9 In some embodiments, the light system 100 includes a lamp stand 30, and the shell 11 is arranged on the lamp stand 30. The lamp stand 30 includes a fixing part 31 that is used to be connected with an external support, so that the user can install and fix the light system 100 to the outside, thereby freeing the hands and effectively improving the user experience.

[0082] The film and television lamp 20 is rotatably arranged on the lamp stand 20, so as to enable the user to adjust the direction and angle of the light emitted by the film and television lamp 20, and meet the shooting of various scenes. Exemplarily, the lamp stand 20 is substantially in a U-shaped structure.

[0083] For the light reflecting cover 10 of the present application, a shell 11 and a mirror surface reflecting plate 12 are included. The interior of the shell 11 is provided with a plurality of mounting surfaces 113, each of which extends from the small caliber end 111 of the shell 11 towards the large caliber end 112. The mirror surface reflecting plate 12 is of an integral structure. The mirror surface reflecting plate 12 includes a body 121 and a plurality of creases 122. The creases 122 divide the body 121 into a plurality of light reflecting bodies 123, which are provided on the mounting surfaces 113 one by one. The plurality of light reflecting bodies 123 enclose a light reflecting cavity 124. It can be understood that the present application causes the mirror surface reflecting plate 12 to bend to form the light reflecting cavity 124 by providing the creases 122, and then is fixed in the interior of the shell 11. Compared with the light reflecting cover 10 of the prior art which is manufactured by a spinning process, the process does not cause damage to the surface of the mirror surface reflecting plate 12, thereby ensuring that the light reflecting cover 10 has a high reflectivity.

[0084] The above embodiments are only illustrative of the structure, and the structures in the embodiments are not fixedly combined. In the absence of structural conflicts, the structures in the embodiments can be used in any combination.
