[0040] See also Figures 1 to 4 This embodiment provides a lighting system, which includes a lighting attachment 200 and an angle adjuster 100 arranged on the lighting attachment 200.

[0041] The light attachment 200 can be a film reflector, a soft light board, or a light board. Due to the lighting requirements of the photography scene, it is often necessary to adjust the spatial position of the light attachment 200 so that it can reflect or illuminate different places. However, the light attachment 200 is generally set at a high place, which is not convenient for users to adjust.

[0042] In this embodiment, the angle adjuster 100 is disposed on the light accessory 200 to automatically adjust the spatial position of the light accessory 200, so that the user does not need to manually adjust the angle position of the light accessory 200, thereby improving the convenience of use.

[0043] In some embodiments, the lighting system further includes a control terminal. The control terminal is in signal communication with the angle adjuster 100 via a wired or wireless manner. The angle adjuster 100 can receive a control signal from the control terminal and control the spatial position of the lighting accessory 200 according to the control signal.

[0044] The control terminal may be a control box, a console, a remote controller, or an APP in a smart device, etc. The control terminal is arranged at a place where the user can conveniently operate, so that the user does not need to manually adjust the position of the light attachment 200 at a high place, thereby improving the efficiency of light adjustment at the photography scene.

[0045] In some embodiments, the lighting system further includes a support frame, which is used to support the angle adjuster 100 so that the angle adjuster 100 can be quickly fixed to the ground or wall, thereby achieving rapid installation of the lighting accessory 200.

[0046] See also Figures 6 to 11 In this embodiment, the angle adjuster 100 includes a base 110 , a first movable unit 120 , a second movable unit 130 , a connecting member 132 and a driving unit 140 .

[0047] Among them, Figure 6 As shown, the base 110 is used to be fixedly connected to an external support frame. The first movable unit 120 is slidably arranged on the base 110. The second movable unit 130 is arranged on a side of the first movable unit 120 away from the base 110 and is slidably connected to the first movable unit 120; a connecting member 132 is fixedly connected to a side of the second movable unit 130 away from the first movable unit 120, and the connecting member 132 is used to connect to the lighting accessory 200.

[0048] like Figure 7 As shown, the driving unit 140 is connected to the first movable unit 120 and the second movable unit 130, so as to be able to drive the first movable unit 120 to reciprocate in the first direction relative to the base 110, and to drive the second movable unit 130 to reciprocate in the second direction relative to the first movable unit 120, thereby adjusting the spatial position of the lighting accessory 200.

[0049] By automatically controlling the spatial position of the lighting accessory 200 on the angle adjuster 100 through the driving unit 140, it is convenient for the lighting engineer to accurately control any position of the lighting accessory 200 such as the movie reflector, thereby greatly saving time and labor and improving work efficiency.

[0050] like Figure 8 and Fig. 9 As shown, in some embodiments, the first direction and the second direction are located on a horizontal plane perpendicular to the connecting rod 111 of the base 110 , and the first direction and the second direction are perpendicular to each other to facilitate precise control of the spatial position of the lighting accessory 200 .

[0051] In this embodiment, the first movable unit 120 swings back and forth in a first direction relative to the base 110 , and the second movable unit 130 swings back and forth in a second direction relative to the first movable unit 120 .

[0052] That is, the first movable unit 120 and the second movable unit 130 make arc-shaped simple pendulum motions in two mutually perpendicular directions, so that the angles of the light accessory 200 connected thereto are changed in the first direction and the second direction, so as to adjust the pitch and horizontal angles of the light accessory 200, so as to quickly and accurately adjust the light output angle of the light accessory 200 to adapt to different lighting scenes.

[0053] See also Figure 8 In some embodiments, a first guide portion 113 is provided on the base 110 , and the first guide portion 113 is arc-shaped and arranged along a first direction.

[0054] A second guide portion 125 is provided on one side of the first movable unit 120 facing the base 110, and the second guide portion 125 matches the first guide portion 113. The second guide portion 125 is slidably connected to the first guide portion 113, so that the first movable unit 120 can swing back and forth along the arc-shaped first guide portion 113.

[0055] See also Figure 8 and Fig. 9 A third guide portion 126 is provided on a side of the first movable unit 120 away from the base 110 . The third guide portion 126 is arc-shaped and arranged along the second direction.

[0056] A fourth guide portion 1313 is provided on one side of the second movable unit 130 facing the first movable unit 120. The fourth guide portion 1313 matches the third guide portion 126 and is slidably connected to the third guide portion 126, so that the second movable unit 130 can swing back and forth along the arc-shaped third guide portion 126.

[0057] Specifically, the first movable unit 120 and the base 110 are slidingly guided by the first guide portion 113 and the second guide portion 125 arranged along the first direction; the first movable unit 120 and the second movable unit 130 are slidingly guided by the third guide portion 126 and the fourth guide portion 1313 to achieve angle adjustment of the lighting accessory 200 in two directions.

[0058] See also Figure 8 and Fig. 9 In some embodiments, the first guide portion 113 and the third guide portion 126 are arc-shaped slide groove structures; the second guide portion 125 and the fourth guide portion 1313 are arc-shaped boss structures.

[0059] The curvature of the slide groove structure is the same as the curvature and length of the boss structure, which can not only limit the swing trajectory of the first movable unit 120 and the second movable unit 130, but also increase the curvature of each movable unit, thereby expanding the angle adjustment range of the lighting accessory 200.

[0060] It is conceivable that the specific structural shapes of the guide parts between the base 110 and the first movable unit 120 and between the first movable unit 120 and the second movable unit 130 can be interchanged or constructed in other shapes as long as the sliding guidance between the movable units can be achieved.

[0061] See also Figure 8 and Fig. 9 In some embodiments, the driving unit 140 includes a first driving component, which is disposed between the base 110 and the first movable unit 120 and is used to drive the first movable unit 120 to swing in a first direction of the base 110 .

[0062] like Fig. 9 As shown, the first driving assembly includes a first driving motor 141 , a first driving tooth 142 and a first rack 143 .

[0063] The first rack 143 is fixed on the base 110 , and is arc-shaped and arranged along the first direction. The curvature of the first rack 143 is the same as that of the first guide portion 113 , and the first rack 143 and the first guide portion 113 are parallel to each other.

[0064] The first driving motor 141 is fixed in the first movable unit 120 . A first driving tooth 142 is provided at a power output end of the first driving motor 141 . The first driving tooth 142 is meshed with a tooth groove on the first rack 143 .

[0065] When the first driving motor 141 drives the first driving tooth 142 to move on the first rack 143 , the first movable unit 120 is driven to swing in an arc shape along the trajectory of the first guide portion 113 , so as to change the angle of the lighting attachment 200 in the first direction.

[0066] Please continue reading Fig. 9 In some embodiments, the driving unit 140 further includes a second driving component, which is disposed between the first movable unit 120 and the second movable unit 130 and is used to drive the second movable unit 130 to swing in a second direction perpendicular to the first direction.

[0067] The second driving assembly includes a second driving motor 144 , a second driving tooth 145 and a second rack 146 .

[0068] The second rack 146 is fixed on the second movable unit 130 , and is arc-shaped and extends along the second direction. The arc of the second rack 146 is the same as that of the fourth guide portion 1313 , and is parallel to the fourth guide portion 1313 .

[0069] The second drive motor 144 is fixed in the first movable unit 120 . The power output end of the second drive motor 144 is provided with the second drive teeth 145 . The second drive teeth 145 mesh with the tooth grooves on the second rack 146 .

[0070] The second driving motor 144 drives the first driving tooth 142 to rotate, so that the second rack 146 moves relative to the second driving tooth 145, thereby driving the second movable unit 130 to swing back and forth along the trajectory of the third guide portion 126 of the first movable unit 120 to change the angle of the lighting attachment 200 in the second direction.

[0071] It should be understood that the first drive motor 141 and the second drive motor 144 in this embodiment are stepper motors or servo motors, which can receive external control signals to rotate. The drive motor drives the first movable unit 120 and the second movable unit 130 by driving teeth and cooperating with arc-shaped racks, which can make the swing angle control of the light accessory 200 more precise, so that the adjustment accuracy of the light accessory 200 is higher.

[0072] It is conceivable that, in some other embodiments, the driving unit 140 may also be a driving motor that cooperates with a multi-link mechanism to achieve arc-shaped swinging of the first movable unit 120 and the second movable unit 130 .

[0073] See also Figure 8 In some embodiments, the base 110 includes a connecting rod 111 and a positioning platform 112 disposed on the connecting rod 111 .

[0074] The connecting rod 111 is used to connect with the external support frame. The connecting rod 111 is also provided with a rotating button 1111, which is used to abut against the top of the support frame so that the connecting rod 111 can be fixed on the support frame.

[0075] See also Figure 8 and Fig.11 In some embodiments, the positioning platform 112 includes a platform body 1121 and a bottom plate 1122 detachably connected to both ends of the platform body 1121 .

[0076] The top surface of the table body 1121 is an arc-shaped surface, which has the same arc as the first guide portion 113 , so as to prevent the first movable unit 120 from interfering with the base 110 when swinging.

[0077] The bottom plates 1122 at both ends of the stage body 1121 are arranged along the first direction, that is, the bottom plates 1122 are arranged perpendicular to the second direction. The two bottom plates 1122 protrude from the opposite side walls of the stage body 1121 and are provided with first guide portions 113. The first guide portions 113 are arranged on the detachable bottom plates 1122 to facilitate the disassembly and assembly of the base 110 and the first movable unit 120.

[0078] See also Fig. 9 and Fig.11 In some embodiments, the first movable unit 120 includes a frame body 121, panels 122 detachably connected to both ends of the frame body 121, side panels 123 detachably connected to both sides of the frame body 121, and a top plate 124 arranged on the frame body 121.

[0079] The first driving motor 141 and the second driving motor 144 are fixed perpendicularly to each other inside the frame body 121 .

[0080] The panel 122 is disposed along the first direction and is perpendicular to the second direction. A second guide portion 125 is disposed at the bottom of the panel 122 for docking with the first guide portion 113 on the base 110 .

[0081] The side plate 123 is arranged along the second direction and is perpendicular to the first direction. A third guide portion 126 is provided on the top of the side plate 123 for docking with the fourth guide portion 1313 on the second movable unit 130 .

[0082] Specifically, the side panel 123, the panel 122, and the top panel 124 of the first movable unit 120 are all connected to the frame body 121 by screws, which not only facilitates the installation of the first drive motor 141 inside the first movable unit 120 and the first drive motor 141, but also facilitates the installation and disassembly between the first movable unit 120 and the second movable unit 130.

[0083] Please continue reading Figure 8 and Fig. 9 In some embodiments, the second movable unit 130 includes a plate body 1311 and ear plates 1312 disposed on both sides of the plate body 1311. The side of the ear plate 1312 facing the first movable unit 120 is arc-shaped to prevent interference between the second movable unit 130 and the first movable unit 120 when they move relative to each other. The fourth guide portion 1313 is disposed on the outer side walls of the two ear plates 1312.

[0084] See also Figure 5 and Fig. 9 In some embodiments, the connecting member 132 includes a fixed slider 1321 , a slider bracket 1322 , a clamping frame 1323 and a locking knob 1324 .

[0085] The fixed slider 1321 is used to connect with the fixed slide groove 210 on the lighting attachment 200. The slider bracket 1322 is fixedly connected to the side of the fixed slider 1321 facing the second movable unit 130, and is fixedly connected to the second movable unit 130. The clamping frame 1323 is located on the side of the slider bracket 1322 facing the second movable unit 130; the clamping frame 1323 has abutment portions protruding toward the fixed slider 1321 on both sides.

[0086] The locking knob 1324 connects the clamping frame 1323 to the slider bracket 1322; the locking knob 1324 can drive the clamping frame 1323 to move toward the slider bracket 1322, so that the abutment portion on the clamping frame 1323 abuts against the fixed slide groove 210 on the light accessory 200 on the fixed slider 1321 to lock the light accessory 200.

[0087] Specifically, the locking knob 1324 includes a screw rod, a nut and a spring. The top of the screw rod is fixedly connected to the slider bracket 1322, and the other end of the screw rod extends downward and passes through the clamping frame 1323 and is connected to the nut. The spring is arranged on the screw rod and is located between the slider bracket 1322 and the clamping frame 1323.

[0088] After the light attachment 200 is docked with the fixed slider 1321, the nut is then rotated to make the nut abut against the clamping frame 1323, so that the clamping frame 1323 and the slider bracket 1322 are close to each other. The abutting portion on the clamping frame 1323 abuts against the lower side of the light attachment 200 to lock the light attachment 200. When the light attachment 200 needs to be replaced, the nut only needs to be rotated in the opposite direction to make the clamping frame 1323 away from the slider bracket 1322, so that the light attachment 200 can be unlocked.

[0089] See also Figure 8 and Fig.10 In some embodiments, the angle adjuster 100 further includes a limiting column 114. The limiting column 114 is disposed on the base 110, and a limiting groove 1221 matching the limiting column 114 is disposed on the first movable unit 120. The limiting column 114 is accommodated in the limiting groove 1221 to limit the swing arc of the first movable unit 120.

[0090] Specifically, the limiting column 114 is disposed on the arc surface of the positioning platform 112 , and the limiting groove 1221 is disposed at the bottom of the panel 122 . The swing arc of the first movable unit 120 is limited by the cooperation between the limiting column 114 and the limiting groove 1221 .

[0091] It is conceivable that a matching limiting portion may be provided between the first movable unit 120 and the second movable unit 130 to limit the swinging arc of the second movable unit 130 .

[0092] See also Fig. 9 In some embodiments, the angle adjuster 100 further includes a control circuit board 127 .

[0093] The control circuit board 127 is electrically connected to the first driving motor 141 and the second driving motor 144 in the driving unit 140 to control the working states of the first driving motor 141 and the second driving motor 144 , thereby controlling the spatial angle of the lighting accessory 200 .

[0094] The control circuit board 127 is also provided with a wired signal connector and / or a wireless signal transceiver for receiving external control signals.
