Description

Technical Field

[0001] This utility model relates to the technical field of photographic and video equipment, specifically a photographic lighting accessory and its photographic lighting system. Background Technology

[0002] In the process of photography, there are often situations where flash lighting is needed to supplement light due to insufficient light, especially when shooting close-up. Because the distance between the camera and the subject is relatively close, it often blocks some of the external light. Therefore, flash lighting is commonly used when shooting close-up. However, because the light emitted by the flash is relatively diffused, some areas of the subject are prone to high reflectivity. This phenomenon is particularly obvious when shooting close-up, which is a rather troublesome problem for photographers.

[0003] Therefore, existing technologies need to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application proposes a photographic lighting accessory and a photographic lighting system thereof.

[0005] Firstly, a photographic lighting accessory employs the following technical solution:

[0006] A photographic lighting accessory includes a mounting base and a polarizing lens. The mounting base is used to connect to an external flash unit and has a light-transmitting hole for light emitted by the flash unit to pass through. The polarizing lens is disposed on the light-transmitting hole so that the light emitted by the flash unit can pass through the polarizing lens and then exit.

[0007] Preferably, the polarizing lens is rotatably disposed in the light-transmitting hole.

[0008] Preferably, an adjustment ring is provided on the inner wall of the light-transmitting hole, and a first magnetic ring is provided on the adjustment ring along its own annular direction; a mounting ring is rotatably provided on one end face of the adjustment ring, the inner wall of the mounting ring is used for mounting the polarizing lens, and a second magnetic ring is provided on the mounting ring, the second magnetic ring being used to attract the first magnetic ring so that the mounting ring is mounted on the adjustment ring.

[0009] Preferably, the mounting ring has a convex ring on one end face near the adjusting ring, the outer diameter of the convex ring is smaller than the outer diameter of the mounting ring, the end face of the convex ring away from the adjusting ring is used to abut against the adjusting ring, and the outer side wall of the convex ring is used to abut against the inner wall of the light-transmitting hole, and the second magnetic ring is disposed on the convex ring.

[0010] Preferably, the inner wall of the mounting ring is provided with an abutment ring, which is used to abut against one side of the polarizing lens. The inner wall of the mounting ring is threaded with a mounting and dismounting ring, the outer wall of which is threaded to the inner wall of the mounting ring, and the mounting and dismounting ring is used to abut against the other side of the polarizing lens.

[0011] Preferably, the adjusting ring has a limiting arc groove on one end face that abuts against the convex ring. The two ends of the limiting arc groove are not closed. The convex ring has a limiting pin, which is engaged in the limiting arc groove. When the mounting ring rotates, the limiting pin slides along the length direction of the limiting arc groove.

[0012] Preferably, the mounting base is provided with a pointer, and the mounting ring has a scale on one end face near the adjusting ring that cooperates with the pointer.

[0013] Secondly, a photographic lighting system employs the following technical solution:

[0014] A photographic lighting system includes a photographic lighting accessory and a flash. The mounting base includes a mounting plate and a mounting base. A light-transmitting hole is disposed on the mounting plate. One side of the mounting base is connected to the mounting plate, and the other side is used to connect to the flash. The mounting base is provided with a light-transmitting window for the light from the flash to pass through.

[0015] Preferably, the mounting base is detachably connected to the mounting plate.

[0016] Preferably, the mounting base has a clamp on the side away from the mounting ring. There are two clamps, which are arranged opposite each other so that the flash is held in the area between the two clamps. The clamps have a locking block on the side that is close to each other. The locking block is used to lock the flash into the corresponding position. The locking block has a guide surface on the side away from the mounting base.

[0017] Preferably, the mounting base is provided with a magnetic block, and the flash lamp is provided with a magnetic ring, which is used for the magnetic block to be attracted to it.

[0018] This application reduces interference from scattered and reflected light by setting a polarizing lens on the mounting base, thereby reducing the occurrence of highly reflective areas and improving shooting results. It can effectively prevent scattered and reflected light from different directions from causing localized high reflectivity on the surface of the subject, further meeting the needs of photographers for close-up shooting.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] This application discloses a photographic lighting accessory.

[0034] Reference Figures 1 to 11 A photographic lighting accessory includes a mounting base 1 and a polarizing lens 2. Specifically, the mounting base 1 is used to mount a flash 3. A light-transmitting hole 11 is provided in the middle of the mounting base 1. The cross-section of the light-transmitting hole 11 is circular when viewed from one side of the opening. The light-transmitting hole 11 is used to allow the light emitted by the flash 3 to pass through. The polarizing lens 2 is placed in the light-transmitting hole 11. The light emitted by the flash 3 is emitted from the polarizing lens 2. By passing through the polarizing lens 2, the problem of high local reflection caused by stray light from different directions on the surface of the subject is effectively prevented.

[0035] Reference Figure 2 and Figure 3 In some embodiments, in order to effectively prevent stray light from different directions, the polarizing lens 2 is made rotatable, that is, the polarizing lens 2 is rotatably mounted on the mounting base 1. Since the polarizing lens 2 can only allow light at a predetermined angle to pass through, the polarizing lens 2 is rotated along the direction coaxial with the light-transmitting hole 11 on a plane parallel to the light-transmitting hole 11 to adjust the angle of the polarizing lens 2. This allows the polarizing lens 2 to adjust the angle of the emitted light and intercept light at other angles, thereby effectively preventing stray light from different directions.

[0036] Reference Figures 2 to 6In this embodiment, an adjustment ring 4 is provided on the inner wall of the light-transmitting hole 11. The adjustment ring 4 is circular in shape and is coaxially arranged with the light-transmitting hole 11. A first magnetic ring 41 is provided on the adjustment ring 4, and the first magnetic ring 41 is coaxially arranged with the adjustment ring 4 and is located inside the adjustment ring 4. A mounting ring 5 is rotatably arranged on one end face of the adjustment ring 4. The mounting ring 5 is coaxially arranged with the adjustment ring 4 and is located on the end face of the adjustment ring 4 away from the flash lamp 3. The mounting ring 5 can rotate relative to the adjustment ring 4. A second magnetic ring 51 is coaxially arranged on the mounting ring 5. When the mounting ring 5 is installed on the adjustment ring 4, the second magnetic ring 51 will attract the first magnetic ring 41, so that the mounting ring 5 abuts against the adjustment ring 4 without restricting the movement of the mounting ring 5. That is, during installation and rotation, the mounting ring 5 will always be attracted to the adjustment ring 4 and will not deviate from the adjustment ring 4. When it is necessary to remove it, it is only necessary to pull the mounting ring 5 off with force, which is simple and convenient.

[0037] Reference Figures 2 to 6 In some embodiments, to prevent the mounting ring 5 from falling off due to vibration or other reasons, a convex ring 52 is provided on the end face of the mounting ring 5 near the adjusting ring 4. The convex ring 52 is coaxially arranged with the mounting ring 5, and the outer diameter of the convex ring 52 is smaller than the outer diameter of the mounting ring 5. The second magnetic ring 51 is embedded in the convex ring 52. The end face of the convex ring 52 away from the mounting ring 5 is used to abut against the adjusting ring 4. When the mounting ring 5 is installed on the adjusting ring 4, the outer wall of the convex ring 52 abuts against the inner wall of the light-transmitting hole 11. That is, when the convex ring 52 abuts against the adjusting ring 4, the outer wall of the convex ring 52 abuts against the inner wall of the light-transmitting hole 11, and the mounting ring 5 is outside the light-transmitting hole 11. By restricting the convex ring 52 by the inner wall of the light-transmitting hole 11, the phenomenon that the mounting ring 5 falls off due to shaking and the polarizing lens 2 is prevented from being broken.

[0038] Reference Figures 2 to 6 In some embodiments, a limiting arc groove 42 is provided on the adjusting ring 4. The limiting arc groove 42 is located on one end face of the adjusting arc groove near the mounting ring 5, and the two end walls of the limiting arc groove 42 are closed. A limiting pin 55 is provided on one end face of the mounting ring 5 near the adjusting ring 4. The position of the limiting pin 55 corresponds to the position of the limiting arc groove 42, so that the limiting pin 55 is engaged in the limiting arc groove 42. When the mounting ring 5 is rotated, the limiting pin 55 will also move relative to the limiting arc groove 42. The limiting arc groove 42 restricts the limiting pin 55 on both sides along the length direction, thereby limiting the rotation angle of the mounting ring 5 and thus limiting the rotation angle of the polarizing lens 2. With this design, the polarizing lens 2 has a relatively good effect in reducing the interference of reflected and scattered light within this range. Further fine adjustments can be made within this range, which is convenient for users and can also prevent the entire polarizing lens 2 from falling out due to excessive rotation angle.

[0039] Meanwhile, to facilitate the user's rotation angle, a pointer (not shown in the figure) is provided on the mounting base 1, and a scale (not shown in the figure) is provided on the end face of the mounting ring 5 near the adjusting ring 4. The scale and the pointer are used together to display the rotation angle of the polarizing lens 2, so that the user can accurately adjust the rotation angle of the polarizing lens 2.

[0040] Reference Figures 2 to 6 In some embodiments, an abutment ring 53 is coaxially fixedly provided on the inner wall of the mounting ring 5. The abutment ring 53 is located at the opening of the mounting ring 5 near the convex ring 52. The end face of the abutment ring 53 away from the convex ring 52 is used for the polarizing lens 2 to abut against. In this embodiment, the inner diameters of the convex ring 52 and the abutment ring 53 are the same, and the abutment ring 53 and the convex ring 52 are integrally provided. A mounting and dismounting ring 54 is coaxially provided on the inner wall of the mounting ring 5. The outer wall of the mounting and dismounting ring 54 is threadedly connected to the inner wall of the mounting ring 5. Through the threaded connection between the mounting and dismounting ring 54 and the mounting ring 55, the mounting and dismounting ring 54 abuts against the polarizing lens 2, so that the polarizing lens 2 is stuck between the abutment ring 53 and the mounting and dismounting ring 54. When the polarizing lens 2 is scratched or damaged, the mounting and dismounting ring 54 can be screwed off from the inner wall of the mounting ring 5, and the polarizing lens 2 can be replaced.

[0041] This application also discloses a photographic lighting system, referring to... Figures 1 to 11 The system includes a photography light assembly and a flash unit 3. The mounting base 1 includes a mounting base 13 and a mounting plate 12. The mounting plate 12 is arranged in a ring shape. A pointer is set on the mounting plate 12. A light-transmitting hole 11 is set on the mounting plate 12. The mounting base 13 is provided with a light-transmitting window 131. The flash unit 3 is installed on the other side of the mounting base 13. The light emitted by the flash unit 3 enters through the light-transmitting window 131 of the mounting base 13.

[0042] Reference Figures 1 to 11 In some embodiments, the mounting plate 12 and the mounting base 13 are detachably connected. In this embodiment, the mounting plate 12 is detachably connected to the mounting base 13 by screws, so that the mounting base 13 can be installed according to the shape of the flash head 3.

[0043] Reference Figures 1 to 6In some embodiments, a clamping plate 6 is provided on the side of the mounting base 13 away from the mounting plate 12. There are two clamping plates 6, which are arranged parallel to each other on the upper and lower sides of the light-transmitting window 131. The flash lamp 3 is clamped between the two clamping plates 6. In order to improve the stability of clamping, a locking block 61 is provided on the side of the two clamping plates 6 that is close to each other. A corresponding locking position is provided on the flash lamp 3 for the locking block 61 to be engaged. So when the flash lamp 3 is engaged between the two clamping plates 6, the dual action of the squeezing between the two clamping plates 6 and the locking block 61 can securely install the photographic lighting accessory onto the flash lamp 3 as much as possible.

[0044] In addition, a guide surface 62 is provided on the clip 61. The guide surface 62 is located on the side of the clip 61 away from the mounting base 13. When the flash 3 is inserted between the two clamps 6, the flash 3 will first come into contact with the guide surface 62 on the clip 61. Under the action of the guide surface 62, the two clamps 6 can be opened more easily, so that the installation of the photography lighting accessories is more convenient.

[0045] Reference Figures 7 to 11 In some embodiments, a magnetic block 132 can be provided on the mounting base 13. Multiple magnetic blocks 132 are provided and arranged in a circular pattern. At the same time, a magnetic ring 7 is provided on the flash lamp 3. The magnetic ring 7 is used for the magnetic blocks 132 to be attracted. Therefore, when the photographic lighting accessory is installed on the flash lamp 3, it is only necessary to bring the mounting base 13 close to the flash lamp 3. The connection can be achieved through the attraction between the magnetic ring 7 and the magnetic block 132. Different installation methods can be selected according to different types of flash lamps 3 so that the photographic lighting accessory can be used with more types of flash lamps 3.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
