[0059] See also Figures 1 to 18 This embodiment provides a lighting system, which includes a support frame 100, lighting equipment 200 and an electric controller 300.

[0060] The support frame 100 includes a frame body 110 and an angle adjustment component. An installation space is provided in the frame body 110, and the lighting fixture 200 is arranged in the installation space. The angle adjustment component is arranged on the frame body 110, and is connected to the lighting fixture 200, and can drive the lighting fixture 200 to rotate. The electric controller 300 is arranged on the support frame 100, and is connected to the angle adjustment component, and outputs power to the angle adjustment component, thereby controlling the angle of the lighting fixture 200.

[0061] The electric controller 300 can be added to the existing support frame 100, and electrically control the lighting equipment 200 on the support frame 100, making it convenient for the lighting technician to control the lighting equipment 200 at any angle at a high lamp position, greatly saving time and labor and improving work efficiency.

[0062] See also Figures 1 to 4 In some embodiments, the lighting equipment 200 may be a photographic light effect component such as a lamp, a movie reflector, or a diffuser with adjustable light transmittance. The lighting equipment 200 is disposed on the support frame 100, and the angle adjustment component on the support frame 100 can drive the lighting equipment 200 to rotate to change the spatial angle of the lighting equipment 200.

[0063] See also Figures 15 to 18 In some embodiments, the frame body 110 includes opposite mounting arms 113 , and a mounting space is formed between the two mounting arms 113 , and the mounting space is used to install the lighting fixture 200 .

[0064] The angle adjustment assembly is disposed on the frame body 110 ; the angle adjustment assembly includes an adjustment knob and a rotating assembly. The adjustment knob is transmission-connected to the rotating assembly, and the rotating assembly is connected to the frame body 110 and / or the lighting fixture 200 .

[0065] See also Fig.15 and Fig.16 In some embodiments, the frame body 110 includes a mounting box 112, mounting arms 113 and mounting arms 113 disposed on both sides of the mounting box 112, and the two mounting arms 113 are arranged opposite to each other to form a U-shaped mounting space, and the lighting fixture 200 is located in the mounting space.

[0066] In some embodiments, the support frame 100 further includes a mounting rod 111, which is located on the central axis of the frame body 110. One end of the mounting rod 111 is connected to the angle adjustment assembly on the mounting box 112, and the other end of the mounting rod 111 is used to connect to the external bracket so that the support frame 100 can be fixed to the external bracket.

[0067] See also Figures 15 to 18 In some embodiments, two angle adjustment components are provided, namely a pitch adjustment component 120 and a horizontal adjustment component 130 .

[0068] The pitch adjustment assembly 120 is used to connect with the lighting fixture 200 and can drive the lighting fixture 200 to rotate in the installation space of the frame body 110. The horizontal adjustment assembly 130 is used to connect with the frame body 110 and can drive the frame body 110 to rotate around its central axis.

[0069] like Fig.17 As shown, the adjustment knob of the pitch adjustment assembly 120 is a first adjustment knob 121 , which is disposed on the outer side surface of the free end of the mounting arm 113 . The first adjustment knob 121 can receive the torque output by the electric controller 300 .

[0070] like Fig.17As shown, the rotating assembly of the pitch adjustment assembly 120 is a first rotating assembly 122 . The first rotating assembly 122 is transversely disposed on the free end of the installation arm 113 and is fixedly connected to the lighting fixture 200 in the installation space.

[0071] The first adjusting knob 121 and the first rotating assembly 122 are connected to each other in a transmission manner, so that after the first adjusting knob 121 receives the torque of the electric controller 300 , the first adjusting knob 121 can drive the first rotating assembly 122 to rotate, thereby causing the lighting equipment 200 on the first rotating assembly 122 to rotate around the axis of the first rotating assembly 122 .

[0072] Please continue reading Fig.17 In some embodiments, the pitch adjustment assembly 120 further includes a first worm 123 and a first turbine 124 , and the first adjustment knob 121 and the first rotating assembly 122 are transmitted through the first worm 123 and the first turbine 124 .

[0073] Specifically, the first worm 123 is fixed on the first adjusting knob 121, and the first turbine 124 is fixed on the first rotating assembly 122. The first worm 123 and the first turbine 124 are engaged with each other through gears, so that the vertical torsional force on the first adjusting knob 121 is converted into the horizontal torsional force of the first rotating assembly 122, so that the electric controller 300 can drive the lighting device 200 to perform pitch rotation around the horizontal direction.

[0074] See also Fig.18 In some embodiments, the adjustment knob of the horizontal adjustment assembly 130 is a second adjustment knob 131 , which is arranged on the outer side surface of the free end of the mounting arm 113 in parallel with the first adjustment knob 121 and can receive the torque of the electric controller 300 .

[0075] like Fig.18 As shown, the rotating assembly of the horizontal adjustment assembly 130 is a second rotating assembly 132. The second rotating assembly 132 is disposed on the central axis of the frame body 110, one end of which is connected to the mounting box 112 on the frame body 110, and the other end is connected to the mounting rod 111.

[0076] The second adjusting knob 131 is in transmission connection with the second rotating assembly 132. When the second adjusting knob 131 receives the torque of the electric controller 300, the second adjusting knob 131 can drive the second rotating assembly 132 to rotate, so that the frame body 110 on the second rotating assembly 132 rotates around its axis, thereby making the lighting fixture 200 on the frame body 110 rotate horizontally.

[0077] See also Fig.18In some embodiments, the horizontal adjustment assembly 130 further includes a second turbine 133 , a second worm 134 , a transmission shaft 135 and a plurality of transmission teeth for transmitting the torque of the second adjustment knob 131 to the second rotating assembly 132 .

[0078] Specifically, the second turbine 133 is fixedly connected to the second rotating assembly 132, one end of the second worm 134 is meshed with the second turbine 133, and the other end of the second worm 134 is fixed with a first transmission tooth 136. The second rotating assembly 132 is provided with a second transmission tooth 137.

[0079] The transmission shaft 135 extends along the mounting arm 113 and is located between the first transmission teeth 136 and the second transmission teeth 137. The transmission shaft 135 has a third transmission tooth 138 and a fourth transmission tooth 139 at both ends. The third transmission tooth 138 meshes with the first transmission tooth 136; the fourth transmission tooth 139 meshes with the second transmission tooth 137, so that the torque on the second adjustment knob 131 can be transmitted to the second rotating assembly 132 through the transmission shaft 135, the second worm 134 and the second turbine 133 in sequence, and drive the frame body 110 on the second rotating assembly 132 to rotate around the axis direction of the second turbine 133.

[0080] It should be understood that in some embodiments, the transmission shaft 135 can be a flexible shaft, which is a shaft with very low rigidity and elasticity that can be freely bent for transmission. The flexible shaft can be used to connect two shafts that are not on the same axis and in the same direction to transmit rotational motion and torque. Of course, the transmission shaft 135 can also be multiple rigid shafts, and universal joints are connected at the turning points of the multiple rigid shafts to achieve transmission in different directions or different axes.

[0081] In some embodiments, a receiving box 116 is disposed on the free end of the frame body 110 , and the receiving box 116 is used to fix a portion of the transmission structure of the pitch adjustment assembly 120 and the horizontal adjustment assembly 130 .

[0082] It is conceivable that, in some embodiments, the pitch adjustment assembly 120 and the horizontal adjustment assembly 130 on the support frame 100 can be set either one or together.

[0083] It is conceivable that the rotation axis of the lighting fixture 200 on the support frame 100 is not limited to the horizontal and vertical directions, and the rotation direction of the lighting fixture 200 can be adjusted according to actual usage conditions.

[0084] It is conceivable that the transmission method between the pitch adjustment component 120 and the horizontal adjustment component 130 can also be adjusted according to actual conditions. For example, the second adjustment knob 131 and the second rotating component 132 are transmitted by a belt, chain, etc.

[0085] See also Figures 3 to 7 In some embodiments, the electric controller 300 includes a housing 320 , an electric drive component 310 , and an adapter 340 .

[0086] The housing 320 is detachably connected to the support frame 100, and a receiving cavity is provided in the housing 320. The electric driver 310 is arranged in the receiving cavity for outputting power. The adapter 340 is arranged on the output end of the electric driver 310, and the adapter 340 extends out of the receiving cavity of the housing 320; the adapter 340 can be docked with the angle adjustment component to output the power of the electric driver 310 to the adjustment knob of the angle adjustment component, and drive the angle adjustment component to rotate, so as to drive the frame body 110 and / or the lighting equipment 200 on the rotating component to rotate, so as to change the spatial position of the lighting equipment 200.

[0087] The electric controller 300 outputs power to drive the angle adjustment component to rotate, so that the angle adjustment component drives the frame body 110 and / or the lighting equipment 200 to rotate, so as to quickly adjust the light output angle of the lighting equipment 200, thereby realizing electric control of the lighting equipment 200. Human power is no longer required to control the angle of the lighting equipment 200, which greatly saves the operator's time and labor.

[0088] See also Figure 7 In some embodiments, the electric drive member 310 is provided with two, namely, a pitch motor 311 and a horizontal motor 312. The pitch motor 311 and the horizontal motor 312 are arranged side by side. The adapter 340 is fixed to the power output end of the pitch motor 311 and the horizontal motor 312, and can be connected to the first adjustment knob 121 and the second adjustment knob 131 of the adjustment assembly to achieve power transmission. So that the pitch motor 311 can drive the lighting equipment 200 to rotate in the installation space; the horizontal motor 312 can drive the frame body 110 to rotate horizontally.

[0089] The lighting fixture 200 is driven to rotate by the horizontal motor 312 and the pitch motor 311 , and the operator is no longer required to adjust the lighting fixture 200 by a long pole, which makes the adjustment process of the lighting fixture 200 very convenient.

[0090] See also Figure 4 and Figure 7 In some embodiments, a groove 341 is provided on the end surface of the adapter 340 away from the electric drive 310. An adjustment rod 342 is provided inside the adjustment knob of the angle adjustment assembly. The groove 341 is connected to the adjustment rod 342 to transmit the torque of the electric drive 310 to the adjustment assembly.

[0091] Through the cooperation between the groove 341 and the adjusting rod 342, the electric controller 300 and the adjusting assembly can be quickly connected to achieve the transmission of torque.

[0092] It is conceivable that the adapter 340 also realizes power transmission with the power input end of the angle adjustment component through devices such as pins and gears.

[0093] See also Figure 7 The housing 320 includes a detachably connected front housing 321 and a bottom housing 322. The front housing 321 and the bottom housing 322 enclose a closed accommodating cavity, which is used to accommodate the horizontal motor 312 and the pitch motor 311. The bottom housing 322 extends toward the direction of the adapter 340 and exceeds the end surface of the front housing 321 to form a connecting portion 323, which is used to connect to the support frame 100.

[0094] Furthermore, the inner side surface of the connection portion 323 encloses a semi-enclosed installation cavity, and the installation cavity is used to connect with the receiving box 116 on the support frame 100, so that the electric controller 300 can be stably fixed on the support frame 100.

[0095] See also Figure 3 and Figure 5 In some embodiments, the connection portion 323 is provided with a plurality of mounting holes 325, and the support frame 100 is provided with positioning holes 1162 corresponding to the mounting holes 325. Screws are inserted into the mounting holes 325 and the positioning holes 1162 to fix the electric controller 300 on the support frame 100.

[0096] Specifically, the mounting hole 325 is fixed on the connecting portion 323 of the bottom shell 322 , and the positioning hole 1162 is provided on the receiving box 116 , so that the electric controller 300 can be fixed on the receiving box 116 on the frame body 110 by screws.

[0097] See also Figure 3 , Figure 5 Combined with Fig.16 In some embodiments, the connecting portion 323 is provided with an avoidance hole 324. An axially penetrating first through hole 1221 is provided in the first rotating assembly 122 on the support frame 100, and a bolt 114 connected to the lighting fixture 200 is provided in the first through hole 1221. The bolt 114 can move along the axis direction of the first through hole 1221. The axis of the avoidance hole 324 coincides with the axis of the first through hole 1221, so that the bolt 114 can pass through the avoidance hole 324 and the first through hole 1221 from the outside of the frame body 110 and then connect to the lighting fixture 200.

[0098] Specifically, Figure 3 As shown, a second through hole 1161 is also provided in the center of the receiving box 116. The first through hole 1221, the second through hole 1161, and the avoidance hole 324 are all coaxially arranged, and the bolt 114 can pass through the avoidance hole 324, the second through hole 1161, the first through hole 1221, and the turntable 115 from the outside of the frame body 110 in sequence to be connected to the side wall of the lighting fixture 200.

[0099] When the lighting fixture 200 needs to be disassembled, the operator can also smoothly disassemble and assemble the bolts 114 connected to the lighting fixture 200 without being interfered by the electric controller 300. Therefore, the avoidance hole 324 is provided on the connecting portion 323 so that the operator can disassemble and assemble the lighting fixture 200 without being interfered by the electric controller 300, which facilitates the disassembly and assembly of the lighting fixture 200 and the support frame 100.

[0100] It is conceivable that the housing 320 may also be integrally formed, and the housing 320 and the frame body 110 may also be connected by clamping, riveting, etc. The shape of the housing 320 may also be adjusted according to the shape of the adjustment knob of the angle adjustment assembly.

[0101] See also Figure 7 In some embodiments, the electric controller 300 further includes a control board 330 . The control board 330 is electrically connected to the electric driver 310 to control the torque output of the electric driver 310 , thereby changing the angle of the lighting fixture 200 .

[0102] Specifically, the control panel 330 in this embodiment mainly controls the power output state of the horizontal motor 312 and the pitch motor 311 to control the lighting fixture 200. For example, the control panel 330 can control the pitch motor 311 to rotate forward, rotate backward, or stop rotating, so that the light accessory can be flipped forward or backward by 360° in the installation space.

[0103] In some embodiments, the control board 330 may be loaded with an automatic control program, for example, the horizontal motor 312 and the pitch motor 311 may be programmed to change their angles by 30° every ten minutes.

[0104] In some embodiments, the electric controller 300 further includes a control terminal, which is connected to the control board 330 via a wired cable or a wireless signal.
