Description

Technical Field

[0001] This invention relates to the field of lighting fixture control technology, and in particular to a control method for a lighting fixture system, a lighting fixture system, and a computer program product. Background Technology

[0002] Lighting is a crucial factor in filming, and auxiliary equipment such as light stands are often used to help photographers achieve the desired effects. A light stand typically has two arms, with the light source mounted between them. However, existing light stands usually function as supports, requiring users to remove the light fixture and reinstall it at a different angle when adjustments are needed, making them inconvenient and limiting their functionality. Summary of the Invention

[0003] The main purpose of this application is to provide a control method for a lighting stand system, a lighting stand system, and a computer program product, which allows users to quickly adjust the lighting stand to a preset position without manual disassembly and installation, thus enriching the functionality of the lighting stand and effectively improving shooting efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0005] A control method for a lighting fixture system, the lighting fixture system including a lighting fixture and a control terminal, the control terminal being capable of controlling the movement of the lighting fixture, the control method comprising:

[0006] Receive and send control data, wherein the control data includes mark points, and each mark point corresponds to a movement position of the lamp holder;

[0007] Based on the control data, the lamp holder is controlled to perform corresponding pitch and / or horizontal movement to the corresponding position.

[0008] A lighting fixture system includes a handle and at least one lighting fixture, the handle and the lighting fixture being communicatively connected via a now mode. The handle includes a control unit capable of receiving instructions to control the lighting fixture to perform a control method of the lighting fixture system.

[0009] Beneficial effects:

[0010] This article describes how setting mark points allows users to define a specific shooting angle. When the user needs to adjust the shooting angle of the light stand, they can send a mark point to the light stand via the remote control, causing the light stand to respond quickly and adjust to the position corresponding to that mark point. Therefore, users can quickly adjust the light stand to the preset position without manual disassembly and installation, thus enriching the functionality of the light stand and effectively improving shooting efficiency.

[0023] This article provides a lighting fixture 20, including one or more lighting fixtures 20. Users can control one or more lighting fixtures 20 through a control terminal. The control communication methods include NOW mode control of the lighting fixture 20, 2.4G wireless communication control of the lighting fixture 20, and DMX mode control of the lighting fixture 20. "NOW mode" usually refers to Wi-Fi Neighbor Awareness Networking (NAN), also known as Wi-Fi Aware. This is a low-power, short-range communication protocol that allows devices to discover and communicate directly without the need for traditional Wi-Fi networks (such as routers or hotspots). DMX (Digital Multiplex), also known as DMX512, is a digital control protocol widely used in stage lighting, performance equipment, and architectural lighting. It controls multiple devices (such as lamps) through serial communication, supporting up to 512 channels, each channel corresponding to a function of the device (such as brightness, color, motion, etc.). 2.4G wireless communication refers to wireless transmission technology operating in the 2.4GHz ISM (Industry Science and Medicine) frequency band. This band ranges from 2.400GHz to 2.485GHz and is a globally open and universally used wireless frequency band.13 It utilizes electromagnetic waves to propagate information in free space, modulating data onto a carrier wave in the 2.4GHz band for transmission. The receiving end then demodulates the data, thereby enabling wireless communication between devices.

[0024] In addition, the lamp holder 20 is equipped with function key 1, which can be used to set the lamp holder 20 serial number, set the horizontal and pitch speeds from 0-100%, and operate the centering function (return to origin). Furthermore, function key 1 can be used to control the pitch movement of the lamp holder 20 for manual control. After the lamp holder 20 is powered on, it can automatically identify the control source (control terminal) according to the factory preset priority, with the priority order being DMX control source, 2.4G mode control source, now mode control source, and manual control source decreasing in priority. The lamp holder 20 in this paper includes a pitch axis control motor and a horizontal axis control motor. Both the pitch axis control motor and the horizontal axis control motor use closed-loop control with a single-turn absolute encoder on the output shaft. Therefore, with the single-turn absolute encoder on the output shaft, the control program can obtain the current pitch and horizontal positions after power-on, eliminating the need for centering. Here, the position of each point on the output shaft after a single turn can be known through the encoder; therefore, after power-on, centering is unnecessary, and the position of the lamp holder 20 can be obtained immediately after power-on. This article mainly discusses the control methods for light fixtures in "now" mode, specifically including:

[0025] S100: Receive and send control data, wherein the control data includes mark points, and one mark point corresponds to one movement position of the lamp holder 20.

[0026] In this paper, one or more mark points can be preset. Each mark point includes a pre-defined position on the lamp holder 20. For example, a matrix keyboard 2 can be installed on the handle 10. Each key corresponds to one mark point, i.e., one movement position. When a user presses a key, the control unit of the handle 10 receives the user's control data and sends it to the lamp holder 20. The lamp holder 20 receives and parses the control data sent by the handle 10 control unit, and executes the command, causing the pitch axis control motor and / or the horizontal axis control motor to respond and move to the corresponding position. It is understood that the user can input multiple mark points, each of which can be the same position or different positions, depending on the user's input.

[0027] S200. Based on the control data, control the lamp holder 20 to perform the corresponding pitch and / or horizontal movement to the corresponding position.

[0028] Here, the handle 10 controls the lamp holder 20 to perform corresponding pitch and / or horizontal movements to the appropriate positions. Pitch movement is primarily achieved through a pitch axis control motor, and horizontal movement through a horizontal axis control motor. As mentioned earlier, both the pitch and horizontal axis control motors utilize closed-loop control with a single-turn absolute encoder on the output shaft. Therefore, with the single-turn absolute encoder on the output shaft, the control program can obtain the current pitch and horizontal positions after power-on, eliminating the need for centering. When the lamp holder 20 is in operation, it can move the pitch and horizontal axis control motors forward or backward according to the position corresponding to the mark point.

[0029] In summary, this paper demonstrates that by setting mark points, users can set mark points for a specific shooting angle. When the shooting angle of the light stand 20 needs to be adjusted, the user can send a mark point information to the light stand 20 via the remote control handle 10, causing the light stand 20 to respond quickly and adjust to the position corresponding to that mark point. Therefore, users can quickly adjust the light stand 20 to the preset position without manual disassembly and installation, thus enriching the functionality of the light stand 20 and effectively improving shooting efficiency.

[0030] Furthermore, as mentioned earlier, users can configure a serial number for each light fixture 20 using function key 1, which is equivalent to identifying each light fixture 20. Therefore, according to the control data, controlling the light fixture 20 to perform corresponding pitch and / or horizontal movements to the corresponding positions includes:

[0031] S201. If the received control data includes a certain number of lamp holder 20, according to the number information and mark point information, control the lamp holder 20 with the corresponding number to perform the corresponding pitch and horizontal movement to move to the corresponding position.

[0032] In this document, the remote control handle 10 can be assigned the same serial number. The user controls the lamp holder 20. The handle 10 can also include a switching key, such as an encoder knob. The encoder knob can switch the serial number of the lamp holder 20. For example, after the handle 10 and the lamp holder 20 are connected via now mode communication, the corresponding lamp holder 20 serial number can be selected by using the encoder knob. At this time, the handle 10 is configured to control the lamp holder 20 with that serial number. Furthermore, the user can select any mark point through the matrix keypad 2. The lamp holder 20 with that serial number can then resolve the position corresponding to that mark point and control the pitch axis control motor and the horizontal axis control motor to rotate to the corresponding position. It is understandable that, for example, when the pitch position remains unchanged, the user will see a change in horizontal movement with their naked eye; or when the horizontal position remains unchanged, the user will see a change in pitch movement with their naked eye.

[0033] S202. If the received control data includes unified control instructions for all lighting fixtures, control all lighting fixtures 20 to perform corresponding pitch and / or horizontal movements according to the unified control instructions for all lighting fixtures and the mark point information, so as to move to the corresponding positions.

[0034] On the other hand, the remote control handle 10 can also be set with a unified control command for all lamp holders. Users can operate the encoder knob to switch to the unified control command option for all lamp holders. At this time, the handle 10 is configured to control all lamp holders 20 to rotate to the corresponding position. Furthermore, users can select any mark point through the matrix keypad 2. All lamp holders 20 can resolve the position corresponding to the mark point and control the pitch axis control motor and the horizontal axis control motor to rotate to the corresponding position.

[0035] As mentioned earlier, each mark point in this article corresponds to the position of light fixture 20. This can be achieved through mark point settings. First, this article describes the mark point settings for a specific light fixture 20 number, specifically including:

[0036] If a command to set the mark point mode is received, then enter the mark point setting mode;

[0037] Specifically, this operation can also be performed via function key 1 on the controller 10. For example, it can be performed via, but is not limited to, the encoder knob mentioned earlier. Alternatively, it can be performed via a separate button, such as a joystick or lever. Double-clicking function key 1 can enter the mode switching selection. After the user selects the mark point setting mode, the controller 10 can enter the mark point setting mode. At this time, the user can set each matrix keypad 2 to correspond to one mark point, as follows:

[0038] In the mark point setting mode, if the received information is a certain light fixture 20 serial number, then mark point setting is performed on the light fixture 20 with the corresponding serial number.

[0039] This article also allows setting a mark point for a specific number of lamp holder 20. Specifically, this can be done by using function key 1 on the handle 10, such as rotating the encoder knob to select the corresponding lamp holder 20 number. At this time, the handle 10 is configured to set a mark point for the lamp holder 20 corresponding to that number.

[0040] When setting mark points for the corresponding number of light fixture 20, the corresponding mark point information is received so that the corresponding number of light fixture 20 can save the current position information and the corresponding mark point number, wherein the current position information corresponds to the corresponding mark point information.

[0041] Specifically, the user selects the corresponding mark point number via the matrix keypad 2. The control unit of the handle 10 receives the corresponding mark point number signal, and the corresponding light fixture 20 receives the information, further saving the current position and the corresponding mark point number information. Alternatively, all the light fixtures 20 on site can receive the information, and the light fixture 20 with the corresponding number can verify that the number matches its own number. That is, the light fixture 20 with the corresponding number will save its current position and the corresponding mark point number, and this current position is the position corresponding to the selected mark point. With this setting, the user can input multiple mark point numbers for light fixtures 20 with different numbers, so that the light fixture 20 with the corresponding number can save the positions corresponding to multiple mark point numbers. For example, after the user selects light fixture 20 number 2 and presses the number 2 button on the matrix keypad 2, the control unit of the handle 10 can receive this operation information. Furthermore, the corresponding light fixture 20 with the selected number 2, that is, the light fixture 20 for mark setting, will save its current position information, and the currently saved position information is the position information corresponding to the number 2 button. With this setup, users can mark all No. 2 light fixtures 20 on site. After setting, they can mark one or more No. 2 light fixtures 20 on site.

[0042] Currently, the handle 10 is in mark point setting mode. When the user needs to control the lamp holder 20 with the mark set mentioned above using the handle 10, it needs to be switched to mark point execution mode, as follows:

[0043] If a command for mark point execution mode is received, then enter mark point execution mode.

[0044] Specifically, this operation can also be performed using function key 1 on the controller 10, for example, but not limited to, using the encoder knob mentioned earlier. Alternatively, a separate button can be used, and double-clicking function key 1 can be used to put the controller 10 into mark point execution mode. At this point, the user can then proceed as needed, as follows:

[0045] In mark point execution mode, if the received information is a certain lamp holder 20 serial number, then mark point execution is performed on the lamp holder 20 with the corresponding serial number.

[0046] At this point, to control the target lamp holder 20 serial number, the user needs to select the corresponding lamp holder 20 number by selecting the encoder. After selection, the handle 10 can be used to adjust the position of the lamp holder 20 corresponding to that serial number. It can be understood that the corresponding lamp holder 20 may include one or more. For example, to control the serial number 1 lamp holder 20, when there is only one 1 lamp holder 20, the handle 10 can control that 1 lamp holder 20; when there are multiple 1 lamp holders 20, the handle 10 can control multiple 1 lamp holders 20.

[0047] When the corresponding number of the light fixture 20 is marked, the corresponding mark point information is received so as to control the corresponding number of the light fixture 20 to perform the corresponding pitch and / or horizontal movement to the corresponding position according to the corresponding mark point information.

[0048] Furthermore, the user can select the corresponding mark point number through the matrix keypad 2. For example, if the user selects the first light fixture 20, they can select the second key in the matrix keypad 2. At this time, all light fixtures 20 receive information, and the corresponding first light fixture 20 can recognize and parse that this is information for controlling the first light fixture 20, thereby causing the pitch axis control motor and the horizontal axis control motor to move to the position corresponding to the second key. In some embodiments, among multiple light fixtures 20, the first light fixture 20 can receive information and parse it.

[0049] In summary, this paper describes the control of a specific numbered light stand 20. Users can use the handle 10 to mark one or more light stands 20, allowing the corresponding light stand 20 to be quickly adjusted to the user-input position. This setup greatly simplifies the user's work. For example, during filming, multiple light stands 20 are typically used. The lighting positions, i.e., the lighting angles, can be tested by the filming crew beforehand. During the actual filming, if the angle of a particular light is incorrect—for example, due to a change in position (but not limited to)—the filming crew can quickly adjust the light stand 20 with that number using the handle 10. Alternatively, if the filming crew wants to adjust several of the multiple light stands 20, they can assign the same number to those light stands and then control them using the remote handle 10. This setup greatly facilitates the work of the filming crew.

[0050] On the other hand, during filming, initially, the crew can adjust all light stands 20 to a preset state, and then adjust a particular light stand 20 as needed. A light stand control method is provided for adjusting all light stands 20, specifically including:

[0051] If a command to set the mark point mode is received, then enter the mark point setting mode;

[0052] Specifically, as mentioned earlier, this operation can also be performed using function key 1 on the controller 10. For example, it can be performed using, but is not limited to, the encoder knob mentioned earlier. Alternatively, a separate button can be used; double-clicking function key 1 can be used to put the controller 10 into mark point setting mode. In this mode, the user can set each matrix keypad 2 to correspond to a mark point, as follows:

[0053] In mark point setting mode, if the received information is a unified control command for all light fixtures, then mark points are set for all light fixtures 20;

[0054] Unlike the previous text, this text sets up all light fixtures 20. Specifically, this text can use the function key 1 on the handle 10, such as the encoder knob, to select the unified control command for all light fixtures. At this time, the handle 10 is configured to set the mark point for all light fixtures 20 with this sequence number.

[0055] When setting mark points for some light fixtures 20, the corresponding mark point information is received so that all light fixtures 20 can save their current position information and corresponding mark point number, where the current position information corresponds to the corresponding mark point information.

[0056] Considering that the control method described in this paper can control multiple light stands 20, mark points can be set for all light stands 20. Specifically, this can be done by using function key 1 on the handle 10, such as selecting the unified control command for all light stands using the encoder knob, to enter the mark point input setting for all light stands 20. Furthermore, the corresponding mark point number can be selected via the matrix keypad 2. All light stands 20 save their current position and corresponding mark point information. This setting adds another way for users to control all light stands 20, and the control method includes a custom input function, which can meet the different needs of different shooting personnel, making the functions diverse and rich. Shooting personnel can customize the mark point position information or use other saved data after the mark points are set. Users can control all light stands 20 via the remote control handle 10, specifically including:

[0057] If a command to enter mark point execution mode is received, then enter mark point execution mode;

[0058] Specifically, this operation can also be performed using function key 1 on the controller 10, for example, but not limited to, using the encoder knob mentioned earlier. Alternatively, a separate button can be used, and double-clicking function key 1 can be used to put the controller 10 into mark point execution mode. At this point, the user can then proceed as needed, as follows:

[0059] In mark point execution mode, if the received information is a unified control command for all light fixtures, then mark point execution is performed on all light fixtures 20;

[0060] At this time, the remote control handle 10 can control a specific numbered lamp holder 20 or control all lamp holders 20. Therefore, the user can select the encoder to select a unified control command for all lamp holders, so that the handle 10 can switch to control all lamp holders 20. At this time, the handle 10 is configured to control all lamp holders 20.

[0061] With some light fixtures 20 having marked points set, the corresponding marked point information is received so that all light fixtures 20 can perform corresponding pitch and / or horizontal movement to the corresponding position according to the corresponding marked point information.

[0062] At this time, the user selects the corresponding mark number through the matrix keypad 2, that is, selects a keypad number, for example, selects keypad number 1 in matrix keypad 2, and all the lamp holders 20 can move to the position corresponding to keypad number 1.

[0063] In summary, a method for controlling the movement of all light stands 20 is also provided. Combined with the aforementioned method for controlling the movement of a single light stand 20, and taking into account the work needs of the filming staff in this paper, a multi-point marking method is used to allow the filming staff to control the movement of a single light stand 20 or all light stands 20, which can effectively improve the work efficiency of the filming staff.

[0064] Furthermore, when the filming crew wants to adjust the movement position of a specific light stand 20 or all light stands 20 in real time, this paper also provides a control mode, specifically including:

[0065] S300: If a control mode command is received, then enter control mode;

[0066] As described above, the control mode can also be switched using function key 1. When the control mode is needed, the user can operate function key 1, for example, by double-clicking function key 1. The control unit of the remote control handle 10 receives the user's operation information and enters the mode switching selection. After the user selects the control mode, the handle 10 is configured to control the lamp holder 20 in the control mode. Alternatively, electronic hardware such as a joystick or lever can be used for mode selection.

[0067] S400. In control mode, if the received information is a lamp holder 20 number, then control the lamp holder 20 with the corresponding number; under the control of the lamp holder 20 with the corresponding number, receive the control information from the operation unit 3, and control the lamp holder 20 with the corresponding number to perform pitch and / or horizontal movement to the corresponding position.

[0068] As mentioned above, this paper can control a specific numbered lamp holder 20. This numbered lamp holder 20 can be one or more lamp holders 20 with the same serial number, or it can control all lamp holders 20. Here, we will first explain the control of a specific numbered lamp holder 20. As mentioned above, the remote control handle 10 may include, but is not limited to, an encoder knob and a matrix keypad 2. The user can select the serial number of the controlled lamp holder 20 through the encoder. In addition, the user can also select the serial number of the controlled lamp holder 20 through the matrix keypad 2. Furthermore, the remote control handle 10 also includes operating components 3, such as a dial or joystick. After the user selects the desired number, the user can operate the operating components 3, so that the remote control handle 10 receives the user's operation signal and sends it to the lamp holder 20 on site. After parsing the information, the lamp holder 20 with the corresponding serial number can identify that the serial number information corresponds to its own serial number. This is the instruction that it needs to execute. Therefore, it can control the pitch axis control motor and the horizontal axis control motor to move to the corresponding position in a closed loop. With this setup, if the filming crew feels the lighting angle at the pre-marked location is not perfect, they can switch to control mode and adjust the tilt or horizontal position of the light stand 20 in real time using a joystick. This makes the control of the light stand 20 very flexible and convenient.

[0069] S500. In control mode, if the received information is a unified control command for all light fixtures, then all light fixtures 20 are controlled; under the control of all light fixtures 20, the control information of the operating unit 3 is received, and all light fixtures 20 are controlled to perform pitch and / or horizontal movement to the corresponding position.

[0070] Here, the user can select a unified control command for all light fixtures through the encoder. After the user selects the unified control command for all light fixtures, the user can operate the operating component 3, so that the remote control handle 10 receives the user's operation signal and sends it to all light fixtures 20. After parsing the information, all light fixtures 20 can control the pitch axis control motor and the horizontal axis control motor to move to the corresponding positions in a closed loop.

[0071] On the other hand, considering prioritizing user needs, for both control mode and mark point execution mode, in mark point execution mode, if the remote control handle 10 switches to remote control mode, mark point execution stops.

[0072] This article also provides a computer program product that stores a computer program, which, when executed by a processor, implements the aforementioned control method for the lighting fixture system.
