DETAILED DESCRIPTION

[0046] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0047] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0048] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0049] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0050] See also Figures 1 to 3 An embodiment of the present application provides a reflector, which includes a reflector body 10, a support frame 20, an angle adjustment component 30 and a height adjustment component 40.

[0051] In some embodiments, the reflector body 10 is open at both ends and hollow inside. The openings at both ends of the reflector body 10 are respectively a light inlet 100 and a light outlet 110 arranged concentrically, and the end surface of the reflector body 10 provided with the light inlet 100 is used to connect the light source 50. The inner wall of the reflector body 10 is a reflective surface, and in the direction from the light inlet 100 of the reflector body 10 to the light outlet 110, the extension trend of the reflective surface is a gradually expanding parabola, and the light emitted by the light source 50 is reflected by the reflective surface to form parallel light perpendicular to the plane where the light outlet 110 is located.

[0052] In some embodiments, the two ends of the reflector body 10 are respectively an inlet end face and an outlet end face. The inlet end face is provided with a light inlet 100, and the outlet end face is provided with a light outlet 110. The diameter of the light inlet 100 is smaller than the diameter of the light outlet 110.

[0053] In some embodiments, the support frame 20 includes a base 200 and side arms 210 disposed at both ends of the base 200. The side arms 210 can extend in the same direction, and the two sides can be parallel or slightly at an angle. The side arms 210 and the base 200 are combined to form a semi-enclosed structure, and the semi-enclosed structure can form a receiving space. The reflector body is disposed between the side arms 210 and can be accommodated in the receiving space. The support frame 20 supports and connects the reflector body 10, and the side arms 210 on both sides can protect the reflector body 10 to a certain extent.

[0054] In some embodiments, the side arm 210 can be in the shape of a long plate, or a block structure, which is vertically arranged with the base body 200, so that the semi-enclosed structure formed by the two side arms 210 and the base body 200 is roughly C-shaped when viewed from the front.

[0055] Continue to see Figures 8 to 10 A first through hole 211 is formed on the side arm 210 , and the first through hole 211 extends along the length direction of the side arm 210 to form a long hole. The side of the reflector body 10 is connected to one end of the mounting piece, and the other end of the mounting piece passes through the first through hole 211 from the side arm.

[0056] In some embodiments, a slide groove 212 is provided on the side arm 210, and the slide groove 212 extends along the length direction of the side arm 210. The slide groove 212 and the first through hole 211 are spaced apart and parallel to each other.

[0057] In some embodiments, the height adjustment assembly 40 includes a mounting shaft 400, which passes through the slide groove 212 and the mounting member, and the mounting shaft 400 can move in the slide groove 212, so that the reflector body 10 can adjust the distance between it and the base 200, thereby adjusting the height of the reflector body 10. It can be understood that two slide grooves 212 can be arranged at intervals, arranged on both sides of the first through hole 211, and two corresponding mounting shafts 400 are also arranged, so that the reflector body 10 is smoother when adjusting the height, and the connection with the side arm 210 is more stable after the adjustment is completed.

[0058] In some embodiments, the height adjustment assembly 40 further includes a limit block 410, which is fixed to the mounting shaft 400 and abuts against the side arm 210 to limit the outward or inward movement of the mounting shaft 400, and the direction of limiting the movement depends on whether the position where the limit block 410 is installed is located outside or inside the side arm 210. The limit block 410 can be welded and fixed to the mounting seat, or can be screwed and fixed to the mounting shaft 400, and the cross-sectional area of ​​the limit block 410 is larger than the opening area of ​​the slide slot 212, so that the mounting shaft 400 can be limited to move to one side.

[0059] In some embodiments, the height adjustment assembly 40 also includes a clamping block 420, which is disposed on the mounting shaft 400 and abuts against a mounting member located on the opposite side of the side arm 210 from the limit block 410, that is, when the limit block 410 is located on the inner side of the side arm 210, the clamping block 420 is located on the outer side of the side arm 210, and vice versa.

[0060] In some embodiments, the clamping block 420 and the limiting block 410 can move toward each other to clamp the side arm 210 and the mounting piece, thereby increasing the friction between the limiting block 410, the clamping block 420 and the side arm 210 and the mounting piece. By increasing the friction, the reflector body 10 is locked after moving a corresponding distance relative to the base body 200, thereby achieving the height adjustment of the reflector body 10.

[0061] By setting the clamping block 420 and the limiting block 410, when the reflector body 10 needs to be locked, the two can be made to cooperate with each other to clamp the side arm 210 and the mounting part, so that the reflector body 10 and the side arm 210 can be locked by friction, so that the reflector body 10 can be suspended and locked after the height is adjusted to the right position, which can adapt to different usage requirements, and the reflector body 10 can be lowered to reduce the overall volume of the reflector, which is convenient for the packaging and transportation of the reflector.

[0062] In some embodiments, the height adjustment assembly 40 further includes a height adjustment handle 430. The height adjustment handle 430 includes a connecting portion 431 and a gripping portion 432, one end of the gripping portion 432 being connected to the connecting portion 431. The gripping portion 432 may be in a rod shape, which is convenient for an operator to hold. Among them, one end of the mounting shaft 400 away from the limit block 410 is rotatably connected to the connecting portion 431, so that the height adjustment handle 430 can rotate relative to the mounting shaft 400.

[0063] In some embodiments, a protruding eccentric structure 433 is provided on the rotating surface of the connecting portion. When the connecting portion is connected to the mounting shaft, it can be eccentrically connected, and the rotating axes of the mounting shaft 400 and the connecting portion 431 are staggered from the central axis of the connecting portion 431, so that the connecting portion 431 and the mounting shaft 400 rotate eccentrically, thereby forming a protruding eccentric structure 433 on the rotating surface of the connecting portion 431.

[0064] The eccentric structure 433 can rotate between a first position and a second position during the rotation of the connecting portion 431. In the first position, the eccentric structure 433 of the connecting portion 431 moves toward the limiting block 410 to abut against the pressing block 420. The eccentric structure 433 applies a force to the clamping block 420 in the direction of the limit block 410, so that the clamping block 420 has a tendency to move in the direction of the limit block 410. However, since the limit block 410 is fixed to the mounting shaft 400, the limit block 410 is pressed against one side of the side arm 210, and the clamping block 420 is pressed against the other side of the side arm 210, so that the clamping block 420 and the limit block 410 clamp the side arm 210 and the mounting part, and the friction between the clamping block 420, the limit block 410 and the side arm 210 and the mounting part increases, thereby achieving fixation between the reflector body 10 and the side arm 210, and the first position is the locking position of the reflector body 10 and the side arm 210.

[0065] At the same time, in the second position, the height adjustment handle 430 can be rotated in the opposite direction, the eccentric structure 433 and the clamping block 420 are separated, and the friction between the side arm 210 and the clamping block 420 and the limit block 410 is weakened, thereby releasing the lock between the reflector body 10 and the side arm 210 to adjust the height of the reflector body 10. The second position is the unlocking position of the reflector body 10 and the side arm 210.

[0066] In some embodiments, to facilitate adjustment by the operator, in the first position, the gripping portion 432 of the height adjustment handle 430 can be defined to fit on the side arm 210, and the eccentric structure 433 is pressed against the pressing block 420. In the second position, the gripping portion 432 of the height adjustment handle 430 rotates a certain angle to form a certain angle with the side arm 210, and the eccentric structure 433 is out of contact with the pressing block 420 due to the eccentric rotation of the connecting portion 431, thereby releasing the lock of the reflector body 10.

[0067] In some embodiments, the mounting member includes a rotating shaft 300 and a fixing cover 340. The rotating shaft 300 is connected to the side of the reflector body 10, and the rotating shaft 300 passes through the first through hole 211. The fixing cover 340 is arranged outside the side arm 210 and connected to the rotating shaft 300. The fixing cover 340 can move as the reflector adjusts its height. The fixing cover 340 can also be arranged inside the side arm 210.

[0068] In some embodiments, a mounting hole 345 opposite to the slide groove 212 is provided on the fixing cover 340, the mounting shaft 400 passes through the mounting hole 345, the limit block 410 is arranged on the inner side of the side arm 210, and the clamping block 420 is arranged on the outer side of the side arm 210. When the height adjustment handle 430 is rotated to the first position, the connecting portion 431 forces the clamping block 420 to press against the fixing cover 340, so that the clamping block 420 and the limit block 410 clamp the side arm 210 and the fixing cover 340, the fixing cover 340 and the side arm 210 are locked, and finally the reflector body 10 and the side arm 210 are locked.

[0069] In some embodiments, two mounting holes 345 may be provided, which are arranged on both sides of the rotating hole, corresponding to the two sliding grooves 212 provided on the side arm 210 .

[0070] In some embodiments, the mounting hole 345 includes a first hole section 346 and a second hole section 347 which are sequentially arranged along the direction from the limiting block 410 to the pressing block 420. The opening of the first hole section 346 is smaller than the opening of the second hole section 347, so that the mounting hole 345 forms a stepped hole structure. The pressing block 420 is embedded in the second hole section 347, and the end of the pressing block 420 which is away from the height adjustment handle 430 abuts against the bottom wall of the second hole section 347, so that the pressing block 420 is not exposed in the mounting hole 345, improving the beauty of the outer side of the fixed cover 340, and at the same time, the pressing block 420 is limited by the second hole section 347. Among them, the diameter of the mounting shaft 400 can correspond to the inner diameter of the first hole section 346, so that after the mounting shaft 400 passes through the first hole section 346, the shaking can be reduced.

[0071] In some embodiments, the pressing block 420 may be an annular structure, which is sleeved on the mounting shaft 400 and can be pressed toward the limiting block 410 by the eccentric structure 433 .

[0072] In some embodiments, the clamping block 420 can also be threadedly connected to the mounting shaft 400, so that when the reflector body 10 needs to be locked, the operator can hold the limit block 410 on one side to prevent the mounting shaft 400 from rotating, and screw the clamping block 420 on the other side to screw the clamping block 420 in the direction of the limit block 410, and finally lock the side arm 210 and the fixing cover 340 by relying on the effect of threaded fastening.

[0073] In some embodiments, the height adjustment assembly 40 further includes an elastic reset member 440. The elastic reset member 440 is disposed in the second hole section 347, and the two ends of the elastic reset member 440 are respectively connected to the bottom wall of the second hole section 347 and the pressing block 420. When the height adjustment handle 430 is in the first position, the elastic reset member 440 is in a compressed state, and the elastic reset member 440 accumulates energy. When the height adjustment handle 430 is rotated from the first position to the second position, the elastic reset member 440 changes from the compressed state to the initial state, and the elastic reset member 440 releases energy, thereby exerting a force on the pressing block 420 to move away from the limit block 410, so that the pressing block 420 is released from the close contact with the fixed cover 340, thereby releasing the lock between the fixed cover 340 and the side arm 210, and facilitating the adjustment of the height of the reflector body 10.

[0074] In some embodiments, the elastic return member 440 can be a compression spring, which is sleeved on the installation shaft 400 and guided by the installation shaft 400. The elastic return member 440 can also be an elastic element such as a disc spring or a tension spring.

[0075] In some embodiments, the side arm 210 is provided with a plurality of first plug holes 213 spaced apart along its length direction, and the fixing cover 340 is provided with a second plug hole 348, and the vertical section where the second plug hole 348 is located is coplanar with the vertical section where the plurality of first plug holes 213 are located. When the fixing cover 340 moves relative to the base 200 along with the reflector body 10, the second plug hole 348 can be opposite to one of the first plug holes 213, and the fixing cover 340 is connected to the side arm 210 by means of the latch 349 being inserted into the second plug hole 348 and the corresponding first plug hole 213, so that when the position of the fixing cover 340 needs to be locked, the latch 349 can improve the connection stability between the side arm 210 and the fixing cover 340. Among them, the outer sides of the two slide grooves 212 can be symmetrically provided with a plurality of first plug holes 213, and the fixing cover 340 can be provided with two second plug holes 348 accordingly.

[0076] In some embodiments, a protective plate 450 is further connected to the bottom of the fixed cover 340, and the protective plate 450 extends along the length direction of the side arm 210, so that when the fixed cover 340 is adjusted in height, the protective plate 450 also moves accordingly. Thus, the protective plate 450 covers the area between the bottom end of the first through hole and the fixed cover, preventing the operator from inserting his hand into the first through hole 211 and pinching his hand, thereby playing a certain safety protection role.

[0077] Continue to see Fig.11In some embodiments, the protective plate 450 may include a first protective plate 451 and a second protective plate 452, which are stacked in the inner and outer directions of the side arm 210, the bottom of the fixed cover 340 is connected to the first protective plate 451, and the first protective plate 451 and the second protective plate 452 are respectively provided with a first card slot 453 and a second card slot 454 extending along the length direction of the side arm 210, and the first protective plate 451 is connected to the second protective plate 452 by means of a card pin 455 being engaged with the first card slot 453 and the second card slot 454. The total length of the first protective plate 451 and the second protective plate 452 is greater than the length of the first through hole 211.

[0078] When the height of the reflector body 10 is adjusted to the highest, the top of the second protective plate 452 is connected to the bottom of the first protective plate 451 through the bayonet 455. At this time, the first protective plate 451 and the second protective plate 452 are unfolded to cover the first through hole 211 to the greatest extent.

[0079] When the height of the protective cover body is adjusted to a lower level, the first protective plate 451 moves toward the seat body 200 along with the fixing cover 340 , and the first protective plate 451 gradually overlaps with the second protective plate 452 , thereby accommodating the first protective plate 451 and the second protective plate 452 .

[0080] In some embodiments, guide rails 214 extending along the length direction of the side arm 210 are provided on both sides of the first through hole 211, and both sides of the second protective plate 452 can cooperate with the corresponding guide rails 214, so that the second protective plate 452 can move along the length direction of the side arm 210, thereby guiding the movement of the first protective plate 451 and the second protective plate 452. To improve the aesthetics, the guide rails 214 can be provided on the inner side of the side arm 210, and the first protective plate 451 and the second protective plate 452 are provided on the inner side of the side arm 210.

[0081] In some embodiments, a lifting handle 460 may be further provided on the outer side of the fixing cover 340 , and the lifting handle 460 may facilitate the user to lift the fixing cover 340 , so as to adjust the height and angle of the reflector body 10 .

[0082] In some embodiments, the length of the side arms 210 is not less than the maximum diameter of the reflector body, so that the reflector body can be stored in the semi-enclosed structure formed by the base 200 and the side arms 210, which can greatly reduce the overall volume of the reflector, facilitate the transportation and storage of the reflector, and improve the user experience. The maximum diameter of the reflector body can be the diameter of the reflector body light outlet 110, and when the reflector body is lowered to the lowest position in the horizontal direction, the reflector body 10 can be stored in the semi-enclosed structure.

[0083] In some embodiments, there are two height adjustment assemblies 40, which are respectively arranged on both sides of the reflector body 10 and connected to the two side arms 210, so that the reflector body can be adjusted more smoothly when the height is adjusted, and the connection with the side arms 210 is more stable after the adjustment is completed. It can be understood that the two height adjustment assemblies 40 can be symmetrically arranged about the reflector body 10, so that the reflector body can remain horizontal when the height is adjusted.

[0084] Continue to see Figures 4 to 6 In some embodiments, the angle adjustment assembly 30 includes a rotating shaft 300 and a locking bolt 320. The rotating shaft 300 is rotatably connected to the first through hole 211, so that the reflector body 10 can rotate relative to the support frame 20, thereby adjusting the illumination angle of the reflector. It can be understood that the rotating shaft 300 is fixed on both sides of the reflector body 10, so that the two sides of the reflector body 10 are rotatably connected to the two side arms 210.

[0085] Specifically, a rotating portion 310 is formed on the outer circumference of the rotating shaft 300, and the rotating portion 310 can extend in the radial direction of the rotating shaft 300 to form a disc shape. An arc-shaped groove 311 is provided on the rotating portion 310, and a second through hole opposite to the arc-shaped groove 311 is provided on the fixed cover 340. It can be understood that since the arc-shaped groove 311 extends in an arc shape, the second through hole opposite to the arc-shaped groove 311 can refer to that it is opposite to a part of the arc-shaped groove 311.

[0086] Furthermore, one end of the locking bolt 320 is clamped in the arc groove 311 and can move along the arc groove 311 but cannot rotate. The other end of the locking bolt 320 extends out of the second through hole, so that when the reflector body 10 is rotated to adjust its angle, the locking bolt 320 can move in the arc groove 311 so as not to interfere with the rotation of the reflector body 10.

[0087] In addition, one end of the locking bolt 320 extending out of the second through hole is connected to a clamping block 323, and the clamping block 323 is configured to be screwed in the direction of the rotating part 310, wherein the clamping block and the locking bolt are threadedly connected, so as to use the locking force of the thread to press the rotating part 310 onto the fixed cover 340. After the angle is adjusted to the right position, the locking force is used to lock it without loosening, and the friction provided by the pressing prevents the rotating part 310 from continuing to rotate, so that the reflector body 10 can be locked after rotating to the corresponding angle, so that the rotation angle of the reflector body 10 can be conveniently adjusted, and the user experience is improved. Among them, the clamping block 323 can be a hexagonal nut structure, or a block structure with an internal threaded hole threaded with the locking bolt 320.

[0088] In some embodiments, when the reflector body 10 needs to be rotated to unlock, the clamping block can be rotated away from the rotating part so that there is no friction between the rotating part 310 and the fixing cover 340, and the rotating shaft 300 can drive the reflector body 10 to rotate freely to a corresponding angle.

[0089] In some embodiments, the arc groove 311 can be coaxially arranged with the rotating shaft 300, so that when the rotating shaft 300 rotates, the locking bolt 320 can rotate regularly in the arc groove 311 synchronously. The arc corresponding to the arc groove 311 corresponds to the angular range in which the reflector body 10 can rotate. For example, if the arc of the arc groove 311 is 300°, the range in which the reflector body 10 can rotate is between 0 and 300°. It is understandable that the rotating part 310 can be formed by radially extending from the outer circumference of the rotating shaft 300, or can be a component independent of the rotating shaft 300. The rotating part 310 can be a rotating wheel, which is spaced apart from the outer circumference of the rotating shaft 300 to form the arc groove 311, and the rotating wheel is connected to the outer circumference of the rotating shaft 300 except the arc groove 311 through a connecting structure.

[0090] In some embodiments, the arc groove 311 includes a first groove section 312 and a second groove section 313 arranged in sequence along the direction from the rotating part 310 to the side arm 210, and the opening of the first groove section 312 is larger than the opening of the second groove section 313, so that the arc groove 311 forms a stepped structure in the direction from the rotating part 310 to the fixed cover 340.

[0091] In some embodiments, the angle adjustment assembly 30 further includes an angle adjustment handle 330. The angle adjustment handle 330 is disposed outside the fixed cover 340 and connected to the clamping block 323. The angle adjustment handle 330 can screw the clamping block 323 so that the clamping block 323 can be screwed in the direction of the rotating portion 310. By setting the angle adjustment handle 330 to be connected to the clamping block 323, the user can conveniently operate the clamping block 323 by twisting the angle adjustment handle 330, which is more convenient when adjusting.

[0092] In some embodiments, the angle adjustment assembly 30 may further include an annular clamping portion, which is connected to one end of the locking bolt 320 extending out of the second through hole, and the diameter of the annular clamping portion is larger than the diameter of the second through hole. In this way, when locking, the user can manually pull the locking bolt 320 outward until the locking bolt 320 cannot be pulled outward, and is clamped on the outer surface of the side arm 210 through the annular clamping portion, thereby pressing the rotating part 310 against the inner surface of the fixed cover 340.

[0093] In some embodiments, a gasket may be provided between the inner side of the rotating portion 310 and the fixed cover 340 . The gasket may avoid hard contact between the two and may play a buffering role.

[0094] In some embodiments, a screw hole can be opened at one end of the angle adjustment handle 330 so that the angle adjustment handle 330 can be directly screwed to one end of the locking bolt 320. In this way, by screwing the angle adjustment handle 330, the angle adjustment handle 330 can be directly pressed against the outer surface of the side arm 210.

[0095] In some embodiments, the locking bolt 320 includes a rod 322 and a head 321 connected to one end of the rod 322, the head 321 is clamped in the first slot section 312, and the rod 322 passes through the second slot section 313 and the second through hole in sequence, and the end of the rod 322 away from the head 321 is screwed with the clamping block 323, so that the head 321 can be matched with the shape of the first slot section 312 by setting the shape of the head 321 to be non-rotatable in the first slot section 312, so that when adjusting, the degree of compression between the rotating part 310 and the fixed cover 340 can be adjusted by screwing the angle adjustment handle 330 to achieve locking and unlocking. The head 321 can be rectangular or shaped so as to be non-rotatable in the first slot section 312.

[0096] In some embodiments, a bayonet may be provided on the end surface of the clamping block 323 facing the angle adjustment handle 330, and a channel is provided on the end of the angle adjustment handle 330 opposite to the locking bolt 320, and a plug-in portion is provided on the outer edge of the channel. When adjusting, the locking bolt 320 can be extended into the channel, and the plug-in portion can be inserted into the bayonet of the clamping block 323, so that the angle adjustment handle 330 can be screwed to move the clamping block 323 on the locking bolt 320, and the other end of the locking bolt 320 is engaged in the arc groove 311, so that the clamping block 323 is pressed against the outer side of the fixed cover 340, thereby pressing the rotating part 310 against the inner side of the fixed cover 340.

[0097] In some embodiments, the second through hole and the first through hole 211 are arranged opposite to each other, so that when adjusting the height, the locking bolt 320 can also slide on the first through hole 211 without causing interference.

[0098] In some embodiments, the diameter of the rotating shaft 300 is less than or equal to the width of the first through hole 211 , so that the rotating shaft 300 can rotate in the first through hole 211 and can slide along the length direction of the side arm 210 .

[0099] Furthermore, a rotation hole opposite to the first through hole 211 is provided on the fixed cover 340 , and one end of the rotating shaft 300 passes through the first through hole 211 and is rotationally connected to the rotation hole to realize the rotation connection between the rotating shaft 300 and the fixed cover 340 .

[0100] In some embodiments, by providing the fixing cover 340, the rotation angle of the reflector body 10 can be adjusted while adjusting the height of the reflector body 10. The fixing cover 340 can be a disc-shaped structure, and the central axis of the first through hole 211 passes through the center of the fixing cover 340, so that the fixing cover 340 is more evenly stressed when being pressed.

[0101] In some embodiments, a bearing 350 is also sleeved on the rotating shaft 300, the inner ring of the bearing 350 is fixedly connected to the outer periphery of the rotating shaft 300, and the outer ring of the bearing 350 is fixedly connected to the hole wall of the rotating hole. By providing the bearing 350, the rotating shaft 300 can rotate more smoothly in the rotating hole and reduce mechanical friction.

[0102] In some embodiments, the inner ring of the bearing 350 and the outer periphery of the rotating shaft 300 as well as the outer ring of the bearing 350 and the hole wall of the rotating hole can be fixedly connected by a key connection, or can be fastened by an interference fit.

[0103] In some embodiments, a first step portion 301 is formed on the outer periphery of the rotating shaft 300, and a second step portion 341 is provided on the fixed cover 340 in the rotating hole. The first step portion 301 and the second step portion 341 are spaced apart along the axial direction of the rotating shaft 300, and the bearing 350 is embedded between the first step portion 301 and the second step portion 341 to axially limit the bearing 350, thereby preventing axial movement of the bearing 350 when the rotating shaft 300 rotates.

[0104] In some embodiments, a pointer 343 is provided on the end surface of one end of the rotating shaft 300 passing through the first through hole 211. The pointer 343 extends radially along the end surface of the rotating shaft 300. The pointer 343 can be used to indicate a scale. Correspondingly, a plurality of angle scales 344 are provided on the outer wall surface of the fixed cover 340. The plurality of angle scales 344 are distributed at intervals along the circumference of the rotating hole. The plurality of angle scales 344 are mapped to the rotation angle value of the rotating shaft 300. For example, if the rotating shaft 300 can rotate within a range of 0 to 300°, the rotation angle value of the rotating shaft 300 is between 0 and 300°. The plurality of angle scales 344 can correspond to a plurality of angle values ​​between 0 and 300°, such as 0°, 45°, 90°, 135°, 180°...300°, etc. Among them, the pointer 343 can be in the shape of an acute triangle, and its tip is the pointing end of the pointer 343. Of course, the pointer 343 may also be in the shape of a dot, which is aligned with a certain angle scale 344 , indicating that it points to the angle scale 344 .

[0105] In some embodiments, the pointer 343 can point to different angle scales 344 as the rotating shaft 300 rotates. For example, when the reflector body 10 rotates to the horizontal, the corresponding rotation angle is set to 0°, and the pointer 343 points to the "0°" angle scale 344, indicating that the rotating shaft 300 has rotated 0°. When the reflector body 10 is adjusted upward or downward, the pointer 343 also points to different angle scales 344, indicating that the rotating shaft 300 has rotated the corresponding angle value.

[0106] In some embodiments, by providing a pointer 343 and a plurality of angle scales 344 , the adjustment of the angle of the reflector body 10 can be reflected in real time, which can facilitate the operator to control the angle of the reflector body 10 more accurately.

[0107] In some embodiments, a cover plate 342 is connected to the end surface of the rotating shaft 300 passing through the first through hole 211. The shape of the cover plate 342 can correspond to the shape of the rotating hole so as to just cover the rotating hole. The side of the cover plate 342 facing away from the rotating shaft 300, that is, the outer wall surface of the cover plate 342 is flush with the outer wall surface of the fixed cover 340, which can improve the aesthetics of the fixed cover 340.

[0108] In some embodiments, the pointer 343 is disposed on the cover plate 342, and the pointing end of the pointer 343 is close to the edge of the cover plate 342, so that the operator can observe the angle scale 344 pointed by the pointer 343, and the pointing accuracy is higher.

[0109] In some embodiments, the pointer 343 can also be set on the fixed cover 340, and the angle scale 344 is distributed at intervals along the circumference of the cover plate 342. At this time, the pointer 343 does not move, and the angle scale 344 rotates with the rotating shaft 300. The pointer 343 can also point to different angle scales 344 to obtain the rotation angle value of the rotating shaft 300.

[0110] In some embodiments, there may be two angle adjustment assemblies 30, which are respectively disposed on both sides of the reflector body 10 and respectively connected to the two side arms 210, wherein the two angle adjustment assemblies 30 can be symmetrically disposed on the reflector body 10, so that the reflector body 10 is more stable when rotating.

[0111] Continue to see Figure 12 to Figure 13 In some embodiments, the present application further provides a photographic lighting system, which includes a light source 50 and the above-mentioned reflector. The structure of the reflector has been described above and will not be repeated here.

[0112] The light source 50 can be an LED lamp. The end face of the reflector body 10 provided with the light inlet 100 is connected to the light source 50, and the light emitted by the light source 50 enters the interior of the reflector body 10 through the light inlet 100, and after being reflected by the reflecting surface, forms parallel light perpendicular to the plane where the light outlet 110 is located and is emitted from the light outlet 110.

[0113] Among them, a light source interface 500 may be provided on the end surface of the reflector body 10 provided with the light inlet 100, and the light source 50 is connected to the light inlet 100 through the light source interface 500. A first bracket 510 and a second bracket 520 may be provided on both sides of the light source interface 500, and the first bracket 510 and the second bracket 520 are respectively fixedly connected to the two sides of the light source 50 to achieve a stable connection between the light source 50 and the reflector body 10.

[0114] For the reflector and photographic lighting system in the present application, the reflector includes a reflector body 10, a support frame 20, an angle adjustment assembly 30 and a height adjustment assembly 40. The pitch angle of the reflector body 10 can be manually adjusted by the angle adjustment assembly, which can cover various usage scenarios; the height of the reflector body 10 can be adjusted by the height adjustment assembly, which supports hovering locks at different heights to meet different height requirements, and the reflector body 10 can be lowered to be stored in a semi-enclosed structure, so that the overall volume of the reflector is reduced, which is convenient for packaging and transportation, and saves space and cost.
