Detailed Implementation

[0041] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0044] Please refer to Figures 1 to 4. This embodiment provides a lighting system, which includes a lighting accessory 200 and an angle adjuster 100 disposed on the lighting accessory 200.

[0045] Lighting accessory 200 can be a film reflector, diffuser, or light panel, etc., used in photography and videography. Due to the lighting requirements on set, the spatial position of lighting accessory 200 often needs to be adjusted so that it can reflect or illuminate in different areas. However, lighting accessory 200 is generally installed at a high position, making it inconvenient for users to adjust.

[0046] In this embodiment, by setting the angle adjuster 100 on the lighting accessory 200, the spatial position of the lighting accessory 200 is automatically adjusted, so that the user does not need to manually adjust the angle position of the lighting accessory 200, thereby improving the ease of use.

[0047] In some embodiments, the lighting system further includes a control terminal. The control terminal and the angle adjuster 100 are connected via a wired or wireless signal. The angle adjuster 100 can receive control signals from the control terminal and control the spatial position of the lighting accessory 200 according to the control signals.

[0048] The control terminal can be a control box, console, remote control, or an app on a smart device. Positioning the control terminal in a location easily accessible to the user eliminates the need for manual adjustment of the lighting accessory 200 from a higher location, thus improving the efficiency of lighting adjustments on set.

[0049] In some embodiments, the lighting system further includes a support frame for supporting the angle adjuster 100, so that the angle adjuster 100 can be quickly fixed to the ground or wall, thereby enabling the rapid installation of the lighting accessory 200.

[0050] Please refer to 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 connector 132, and a drive unit 140.

[0051] As shown in Figure 6, the base 110 is used for fixed connection with an external support frame. The first movable unit 120 is slidably mounted on the base 110. The second movable unit 130 is located on the side of the first movable unit 120 opposite to the base 110 and is slidably connected to the first movable unit 120; a connector 132 is fixedly connected to the side of the second movable unit 130 opposite to the first movable unit 120, and the connector 132 is used for connection with the lighting accessory 200.

[0052] As shown in Figure 7, the drive unit 140 is connected to the first movable unit 120 and the second movable unit 130, so that the first movable unit 120 can be driven to reciprocate in a first direction relative to the base 110, and the second movable unit 130 can be driven to reciprocate in a second direction relative to the first movable unit 120, thereby adjusting the spatial position of the light accessory 200.

[0053] The drive unit 140 automatically controls the spatial position of the lighting accessory 200 on the angle adjuster 100, which allows the lighting technician to accurately control any position of the lighting accessory 200, such as the movie reflector, greatly saving time and labor and improving work efficiency.

[0054] As shown in Figures 8 and 9, in some embodiments, the first direction and the second direction are located on the horizontal plane of the connecting rod 111 perpendicular to the base 110, and the first direction and the second direction are perpendicular to each other, so as to facilitate precise control of the spatial position of the lighting accessory 200.

[0055] 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.

[0056] That is, the first movable unit 120 and the second movable unit 130 make arc-shaped pendulum motions in two mutually perpendicular directions, so that the angle of the light accessory 200 connected to them changes in the first direction and the second direction, so as to realize the adjustment of the pitch and horizontal angle of the light accessory 200, and quickly and accurately adjust the light emission angle of the light accessory 200 to adapt to different lighting scenes.

[0057] Please refer to Figure 8. In some embodiments, the base 110 is provided with a first guide portion 113, which is arc-shaped and arranged along a first direction.

[0058] The first movable unit 120 has a second guide portion 125 on the side 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.

[0059] Please refer to Figures 8 and 9. The first active unit 120 is provided with a third guide portion 126 on the side away from the base 110. The third guide portion 126 is arc-shaped and is arranged along the second direction.

[0060] The second movable unit 130 has a fourth guide portion 1313 on the side 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.

[0061] Specifically, the first movable unit 120 and the base 110 are slidably 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 slidably guided by the third guide portion 126 and the fourth guide portion 1313, so as to realize the adjustment of the angle of the light accessory 200 in two directions.

[0062] Please refer to Figures 8 and 9. In some embodiments, the first guide portion 113 and the third guide portion 126 are arc-shaped groove structures; the second guide portion 125 and the fourth guide portion 1313 are arc-shaped boss structures.

[0063] The arc of the chute structure is the same as the arc and length of the boss structure. It can not only limit the swing trajectory of the first movable unit 120 and the second movable unit 130, but also increase the arc that each movable unit can swing, so that the angle adjustment range of the lighting accessory 200 is greater.

[0064] It is conceivable that the specific structural shape of the guide portion 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 into other shapes, as long as the sliding guidance between the movable units can be realized.

[0065] Please refer to Figures 8 and 9. In some embodiments, the drive unit 140 includes a first drive component disposed between the base 110 and the first movable unit 120, for driving the first movable unit 120 to swing in a first direction of the base 110.

[0066] As shown in Figure 9, the first drive assembly includes a first drive motor 141, a first drive gear 142, and a first rack 143.

[0067] The first rack 143 is fixed on the base 110. The first rack 143 is arc-shaped and arranged along the first direction. The arc of the first rack 143 is the same as the arc of the first guide portion 113, and the arc surfaces of the first rack 143 and the first guide portion 113 are parallel to each other.

[0068] The first drive motor 141 is fixed inside the first movable unit 120. The power output end of the first drive motor 141 is provided with a first drive tooth 142, which meshes with the tooth groove on the first rack 143.

[0069] When the first drive motor 141 drives the first drive tooth 142 to move on the first rack 143, it drives the first active unit 120 to swing in an arc along the trajectory of the first guide portion 113, thereby changing the angle of the light accessory 200 in the first direction.

[0070] Please continue to refer to Figure 9. In some embodiments, the drive unit 140 further includes a second drive component, which is disposed between the first active unit 120 and the second active unit 130, and is used to drive the second active unit 130 to swing along a second direction perpendicular to the first direction.

[0071] The second drive assembly includes a second drive motor 144, a second drive gear 145, and a second rack 146.

[0072] The second rack 146 is fixed to the second movable unit 130. The second rack 146 is arc-shaped and extends along the second direction. The arc of the second rack 146 is the same as the arc of the matching third guide portion 126 and fourth guide portion 1313, and is parallel to the arc surfaces of the third guide portion 126 and fourth guide portion 1313.

[0073] The second drive motor 144 is fixed inside the first movable unit 120. The power output end of the second drive motor 144 is provided with the second drive tooth 145, which meshes with the tooth groove on the second rack 146.

[0074] The second drive motor 144 drives the first drive tooth 142 to rotate, so that the second rack 146 moves relative to the second drive 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, so as to change the angle of the light accessory 200 in the second direction.

[0075] 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 motors drive the first movable unit 120 and the second movable unit 130 by engaging with the arc-shaped rack and pinion, which can make the swing angle control of the lighting accessory 200 more precise and the adjustment accuracy of the lighting accessory 200 higher.

[0076] It is conceivable that in some other embodiments, the drive unit 140 may also be a drive motor that works in conjunction with a multi-link mechanism to achieve the arc swing of the first movable unit 120 and the second movable unit 130.

[0077] Please refer to Figure 8. In some embodiments, the base 110 includes a connecting rod 111 and a positioning platform 112 disposed on the connecting rod 111.

[0078] The connecting rod 111 is used to connect with an external support frame. The connecting rod 111 is also provided with a rotary button 1111, which is used to abut against the top of the support frame so that the connecting rod 111 can be fixed to the support frame.

[0079] Please refer to Figures 8 and 11. In some embodiments, the positioning stage 112 includes a stage body 1121 and a base plate 1122 detachably connected to both ends of the stage body 1121.

[0080] The top surface of the platform body 1121 is an arc-shaped surface, which has the same curvature as the first guide part 113, so as to prevent the first movable unit 120 from interfering with the base 110 when it swings.

[0081] The base plates 1122 at both ends of the platform body 1121 are arranged along a first direction, that is, the base plates 1122 are arranged perpendicular to the second direction. The two base plates 1122 protrude from the opposite sidewalls of the platform body 1121 and are provided with first guide portions 113. The first guide portions 113 are set on the detachable base plates 1122 to facilitate the assembly and disassembly of the base 110 and the first movable unit 120.

[0082] Please refer to Figures 9 and 11. In some embodiments, the first active unit 120 includes a frame body 121, panels 122 detachably connected to both ends of the frame body 121, side plates 123 detachably connected to both sides of the frame body 121, and a top plate 124 disposed on the frame body 121.

[0083] The first drive motor 141 and the second drive motor 144 are fixed inside the frame body 121 perpendicular to each other.

[0084] The panel 122 is arranged along the first direction and perpendicular to the second direction. The bottom of the panel 122 is provided with a second guide portion 125 for docking with the first guide portion 113 on the base 110.

[0085] The side plate 123 is arranged along the second direction and is perpendicular to the first direction. The top of the side plate 123 is provided with a third guide portion 126 for docking with the fourth guide portion 1313 on the second movable unit 130.

[0086] Specifically, the side plate 123, front panel 122, and top plate 124 of the first movable unit 120 are all connected to the frame body 121 by screws. This not only facilitates the installation of the first drive motor 141 inside the first movable unit 120, but also facilitates the installation and disassembly between the first movable unit 120 and the second movable unit 130.

[0087] Please refer to Figures 8 and 9. In some embodiments, the second movable unit 130 includes a plate 1311 and ear plates 1312 disposed on both sides of the plate 1311. The side of the ear plate 1312 facing the first movable unit 120 is arc-shaped to prevent interference when the second movable unit 130 moves relative to the first movable unit 120. A fourth guide portion 1313 is disposed on the outer side wall of the two ear plates 1312.

[0088] Please refer to Figures 5 and 9. In some embodiments, the connector 132 includes a fixed slider 1321, a slider bracket 1322, a clamping bracket 1323, and a locking knob 1324.

[0089] The fixed slider 1321 is used to connect with the fixed slide groove 210 on the lighting accessory 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 bracket 1323 is located on the side of the slider bracket 1322 facing the second movable unit 130; the clamping bracket 1323 has abutment portions on both sides protruding towards the fixed slider 1321.

[0090] 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 towards the slider bracket 1322, so that the abutting part on the clamping frame 1323 abuts against the fixing groove 210 on the lighting accessory 200 on the fixed slider 1321, thereby locking the lighting accessory 200.

[0091] Specifically, the locking knob 1324 includes a screw, a nut, and a spring. The top of the screw is fixedly connected to the slider bracket 1322, and the other end of the screw extends downward and passes through the clamping bracket 1323 before connecting to the nut. The spring is disposed on the screw and located between the slider bracket 1322 and the clamping bracket 1323.

[0092] After the lighting accessory 200 is aligned with the fixed slider 1321, the nut is rotated to abut against the clamping bracket 1323, bringing the clamping bracket 1323 and the slider support 1322 closer together. The abutting part on the clamping bracket 1323 abuts against the lower side of the lighting accessory 200, thus locking the lighting accessory 200. When the lighting accessory 200 needs to be replaced, simply rotate the nut in the opposite direction to move the clamping bracket 1323 away from the slider support 1322 to release the locking of the lighting accessory 200.

[0093] Referring to Figures 8 and 10, in some embodiments, the angle adjuster 100 further includes a limiting post 114. The limiting post 114 is disposed on the base 110, and the first movable unit 120 is provided with a limiting groove 1221 that matches the limiting post 114. The limiting post 114 is accommodated within the limiting groove 1221 to limit the swing radius of the first movable unit 120.

[0094] Specifically, the limiting post 114 is set on the arc-shaped surface of the positioning platform 112, and the limiting groove 1221 is set at the bottom of the panel 122. The swing arc of the first active unit 120 is limited by the cooperation of the limiting post 114 and the limiting groove 1221.
