Description

Technical Field

[0001] This application belongs to the field of lighting equipment control technology, and in particular relates to a control method, device and lighting equipment for lighting equipment. Background Technology

[0002] In film and television production and related applications, lighting equipment needs to be compatible with diverse global power supply environments. For example, North America commonly uses 110V AC power systems, often configured with power supply circuits rated at 15A or 20A, while other regions mostly use 220V systems. When high-power lighting equipment is running, if the actual output power exceeds the carrying capacity of the power supply circuit, it can easily trigger problems such as the activation of circuit protection devices, abnormal rise in power supply line temperature, overall power supply disorder, and fluctuations in equipment operating status.

[0003] Currently, most mainstream lighting equipment relies on users manually setting the power limit parameters. However, this manual setting method has significant limitations: users often lack accurate knowledge of local power supply conditions, making it difficult to precisely match the circuit's carrying capacity; and users are prone to neglecting parameter adjustments when equipment is relocated or the power supply scenario changes. These shortcomings cause lighting equipment to frequently face power outages, hardware damage, and operational risks in actual use, severely restricting the reliability and safety of lighting systems. Summary of the Invention

[0004] This application provides a control method, device, and lighting equipment for lighting devices, which can solve the technical problem that most existing lighting devices rely solely on users to manually configure the maximum power parameters, and cannot automatically identify the current power supply environment to uniformly manage the power limits, thus leading to potential safety hazards.

[0005] In a first aspect, embodiments of this application provide a method for controlling a lighting device, including: After the lighting equipment is connected to AC power and powered on, the measured input voltage value of the lighting equipment is obtained; Based on the measured input voltage value, the power supply environment type corresponding to the AC power supply is determined; wherein, the power supply environment type includes low-voltage power supply environment and high-voltage power supply environment; When the power supply environment type is determined to be the low-voltage power supply environment, the power value corresponding to the target power level selected by the user in the power selection interface is determined as the output power limit of the lighting equipment. When the power supply environment type is determined to be the high-voltage power supply environment, the output power limit of the lighting equipment is determined based on the preset rated high-voltage output power level or historical high-voltage output power level record. During the operation of the lighting equipment, the actual output power of the lighting equipment is adjusted based on the output power limit value.

[0006] In one possible implementation of the first aspect, determining the power supply environment type corresponding to the AC power supply based on the measured input voltage value includes: If the measured input voltage value is greater than the preset voltage threshold, the power supply environment type is determined to be a high-voltage power supply environment; If the measured input voltage value is less than or equal to the preset voltage threshold, the power supply environment type is determined to be a low-voltage power supply environment.

[0007] In one possible implementation of the first aspect, when determining that the power supply environment type is the high-voltage power supply environment, determining the output power limit of the lighting equipment based on a preset rated high-voltage output power level or a historical high-voltage output power level record includes: When the historical high voltage output power level record exists, the power value corresponding to the most recently recorded historical high voltage output power level is determined as the output power limit. If there is no record of the historical high voltage output power level, the power value corresponding to the preset rated high voltage output power level is determined as the output power limit.

[0008] In one possible implementation of the first aspect, when determining that the power supply environment type is the low-voltage power supply environment, determining the power value corresponding to the target power level selected by the user in the power selection interface as the output power limit of the lighting color device includes: When the power supply environment type is the low-voltage power supply environment, the power value corresponding to the low-voltage default power level is used as the temporary output power limit of the lighting equipment, and the power selection interface is displayed. In response to the target power level selected by the user on the power selection interface, the current output power limit is updated to the power value corresponding to the target power level, and the power selection interface is closed.

[0009] In one possible implementation of the first aspect, the method includes: While the power selection interface is displayed and not closed, if no user operation to select a target power level is received on the power selection interface, the temporary output power limit is maintained as the output power limit, and the power selection interface remains displayed.

[0010] In one possible implementation of the first aspect, the method includes: The power selection interface is displayed synchronously on both the local end of the lighting device and the client communicating with the lighting device. After the user selects the target power level in the power selection interface on the local terminal, the output power limit is updated and the power selection interface on the local terminal is closed. Simultaneously, the power selection interface on the client side is automatically closed; or, After the user selects the target power level on the power selection interface of the client, the output power limit is updated and the power selection interface of the client is closed. At the same time, the power selection interface of the local terminal is automatically closed.

[0011] In one possible implementation of the first aspect, after determining the power value corresponding to the target power level selected by the user in the power selection interface as the output power limit of the lighting device when the power supply environment type is determined to be the low-voltage power supply environment, the method further includes: In response to the user's power modification command, the power selection interface is displayed so that the user can reselect the target power level on the power selection interface.

[0012] In one possible implementation of the first aspect, after determining the power value corresponding to the most recently recorded historical high-voltage output power level as the output power limit when the historical high-voltage output power level record exists, the method further includes: If the output power limit is lower than the preset power threshold, a prompt message is displayed to the user. The prompt message indicates that the current output power limit of the lighting device is too low and the output power limit can be adjusted upward according to usage needs.

[0013] Secondly, embodiments of this application provide a control device for a lighting equipment, comprising: The measured voltage acquisition module is used to acquire the measured input voltage value of the lighting equipment after the lighting equipment is connected to AC power and powered on. The power supply environment determination module is used to determine the power supply environment type corresponding to the AC power supply based on the measured input voltage value; wherein, the power supply environment type includes low-voltage power supply environment and high-voltage power supply environment; The first limit determination module is used to determine the power value corresponding to the target power level selected by the user in the power selection interface as the output power limit of the lighting device when the power supply environment type is determined to be the low-voltage power supply environment. The second limit determination module is used to determine the output power limit of the lighting equipment based on a preset rated high voltage output power level or a historical high voltage output power level record when the power supply environment type is determined to be the high voltage power supply environment. An output power control module is used to adjust the actual output power of the lighting equipment during operation, with the output power limit value as a constraint.

[0014] Thirdly, embodiments of this application provide a lighting device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the control method of the lighting device described in any of the above claims.

[0015] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the control method for the lighting device described in any of the above claims.

[0016] Fifthly, embodiments of this application provide a computer program product that, when run on a terminal device, causes the terminal device to execute the control method for the lighting device described in any of the first aspects.

[0017] The beneficial effects of the embodiments in this application compared with the prior art are: This application provides a control method for lighting equipment, comprising: after the lighting equipment is connected to an AC power source and powered on, acquiring the measured input voltage value of the lighting equipment; determining the power supply environment type corresponding to the AC power source based on the measured input voltage value; wherein, the power supply environment type includes a low-voltage power supply environment and a high-voltage power supply environment. Then, when the power supply environment type is determined to be a low-voltage power supply environment, determining the power value corresponding to the target power level selected by the user in the power selection interface as the output power limit of the lighting equipment; when the power supply environment type is determined to be a high-voltage power supply environment, determining the output power limit of the lighting equipment based on a preset rated high-voltage output power level or a historical high-voltage output power level record. During the operation of the lighting equipment, the actual output power of the lighting equipment is adjusted using the output power limit as a constraint. This method achieves intelligent constraint of power adjustment by automatically acquiring the measured input voltage value and dynamically determining the power supply environment type and output power limit, effectively solving the problem of power interruption and equipment damage caused by manual setting of power parameters by the user. It can automatically adapt to different power supply environments, avoid power interruption and equipment damage caused by improper power settings, and improve system reliability and user operation convenience.

[0026] Traditional lighting equipment lacks an automatic power supply environment type identification mechanism, resulting in the inability to dynamically adjust output power limits based on the actual input voltage. This issue leads to inconsistent power management strategies across different power supply systems, impacting system stability and equipment reliability. Specifically, when lighting equipment operates under high load, if the output power exceeds the power supply circuit's capacity, it can easily trigger circuit breaker tripping, power cord overheating, and power supply system malfunctions. In severe cases, this can cause unstable lighting operation, threatening user safety.

[0027] For example, on film sets in North America, lighting equipment is connected to a 110V / 15A power supply circuit and operates at high power. Because the lighting equipment cannot automatically recognize this low-voltage environment, users can only manually configure the maximum power parameters. In practice, if users fail to manually configure the maximum power parameters in time, when multiple lighting devices are simultaneously outputting high brightness, the total power exceeds the 15A circuit's capacity, causing frequent circuit breaker tripping, abnormally high power cord temperatures, forced interruptions to filming, and unstable equipment operation, affecting filming quality.

[0028] If these problems are not addressed, the power supply system will be under constant risk of overload, with frequent circuit breaker tripping. This will not only accelerate the aging of power line insulation but may also pose a risk of electrical fires. Simultaneously, lighting equipment will frequently restart due to unstable power supply, subjecting core components to abnormal stress and shortening their lifespan. Furthermore, users will need to repeatedly troubleshoot power supply faults, increasing operational complexity, reducing work efficiency, and potentially leading to more serious safety accidents due to misoperation.

[0029] In this regard, this application provides a method for controlling a lighting device. Please refer to [link / reference]. Figure 1 , Figure 1 This is a flowchart illustrating a control method for a lighting device according to an embodiment of this application. As an example and not a limitation, this method can be applied to or operated in a controller of a lighting device, and the method includes: S11. After the lighting equipment is connected to AC power and powered on, obtain the measured input voltage value of the lighting equipment.

[0030] S12. Determine the power supply environment type corresponding to the AC power supply based on the measured input voltage value; the power supply environment type includes low-voltage power supply environment and high-voltage power supply environment.

[0032] S14. When the power supply environment type is determined to be a high-voltage power supply environment, the output power limit of the lighting equipment is determined based on the preset rated high-voltage output power level or historical high-voltage output power level records.

[0033] S15. During the operation of the lighting equipment, the actual output power of the lighting equipment shall be adjusted with the output power limit as a constraint.

[0034] Lighting equipment refers to devices used to provide illumination or special lighting effects, such as film and television lights and stage lights. This type of lighting equipment typically requires an external power source to obtain the electrical energy needed for operation, and its light output intensity can be adjusted according to usage requirements. AC power refers to the external power supply system that provides alternating current to the lighting equipment. The voltage and current direction of this AC power supply change periodically, and it is a commonly used power supply method for most electronic devices (including lighting equipment).

[0035] The measured input voltage value can be understood as the power supply voltage value actually measured by the internal or external voltage detection module of the lighting equipment after it is connected to AC power and powered on. This measured input voltage value can reflect the voltage level of the current power supply environment.

[0036] Power supply environment type can be understood as a classification of the power supply characteristics of the current AC power source based on the measured input voltage value. For example, the power supply environment type can be divided into high-voltage power supply environment or low-voltage power supply environment according to the voltage level, thus adapting to the power standards of different countries or regions.

[0037] Output power limit refers to the upper limit set on the maximum permissible output power of lighting equipment to ensure its safe and stable operation and avoid overloading the power supply system. This output power limit can be dynamically adjusted according to the power supply environment type. Actual output power refers to the power actually output by the lighting equipment during operation, based on the control commands and current operating status of the equipment. This actual output power is usually directly related to the brightness or luminous efficacy of the lighting equipment and is constrained by the output power limit.

[0038] Specifically, after the lighting equipment is connected to AC power and powered on, it is necessary to obtain the measured input voltage value of the lighting equipment. In some examples, after the lighting equipment is powered on, the power adapter module inside the lighting equipment is powered on and enters a voltage detection ready state. The power adapter module continuously collects the input AC mains power of the currently connected AC power supply, completes voltage sampling and signal processing, and calculates the measured input voltage value of the current lighting equipment. The power adapter module encapsulates the calculated measured input voltage value into a communication message through a hardware communication line (such as the differential serial communication standard RS-485 bus) and sends the voltage feedback data to the controller of the lighting equipment. The lighting controller continuously monitors the hardware communication bus, identifies and receives the feedback message carrying the measured voltage value uploaded by the power adapter module, and performs data parsing on the received feedback message to extract the voltage data carried in the message, ultimately completing the reading and acquisition of the measured input voltage value of the lighting equipment.

[0039] After obtaining the measured input voltage value, it is necessary to determine the power supply environment type corresponding to the AC power source based on this value. In some examples, the controller of the lighting equipment has multiple pre-stored correspondences between voltage ranges and power supply environment types. For example, when the measured input voltage value is within the range of 110V-180V, it is determined to be one power supply environment type; when the measured input voltage value is greater than 180V, it is determined to be another power supply environment type. The controller determines the current power supply environment type by comparing the measured voltage value with these preset ranges.

[0040] After determining the AC power supply environment type, the output power limit of the lighting equipment can be determined based on this environment type. This output power limit aims to prevent overloading of the lighting equipment or stress on the power supply system. Specifically, when the power supply environment type is determined to be a low-voltage environment, the power value corresponding to the target power level selected by the user in the power selection interface is determined as the output power limit. That is, when the power supply environment type is a low-voltage environment, the user is allowed to independently select the required target power level through the interactive interface (i.e., the power selection interface), and the power value corresponding to the user-selected target power level is used as the output power limit of the lighting equipment. This method fully considers the user's actual usage needs, provides operational flexibility, and ensures safe operation in most low-voltage power supply circuits.

[0041] In some examples, the lighting device can have a built-in display screen and operation buttons. When a low-voltage power supply environment is detected, a power selection interface automatically pops up. The user selects a power level using the buttons, and upon confirmation, the power value corresponding to the selected target power level is used as the output power limit. Alternatively, in other examples, the lighting device can establish a connection with an external client (such as a mobile app or tablet) via a wireless communication module (such as Wi-Fi or Bluetooth). When the lighting device is in a low-voltage power supply environment, the client app displays a power selection interface. The user selects a power level on the app and sends the selection result to the lighting device. Upon receiving the result, the lighting device determines the power value corresponding to the user-selected target power level as the output power limit.

[0042] Because high-voltage power supply systems typically have higher load-bearing capacity, when the power supply environment is determined to be a high-voltage environment, the output power limit of the lighting equipment can be determined based on a preset rated high-voltage output power level or historical high-voltage output power level records. The historical high-voltage output power level records are a collection of all power levels that the equipment has previously used in high-voltage power supply environments, stored locally, with each record linked to a corresponding operating time and power value. The preset rated high-voltage output power level is usually the maximum or optimal power level determined by the equipment manufacturer according to design specifications and safety standards, designed to ensure the stability and reliability of the lighting equipment in high-voltage environments.

[0043] Then, during the operation of the lighting equipment, the adjustment of its actual output power is strictly constrained by the output power limit. Specifically, the controller of the lighting equipment continuously monitors its current actual output power. When a user requests higher power output from the lighting equipment via the user interface or remote control commands, the controller first compares the requested power value with the established output power limit. If the requested power value exceeds the output power limit, the actual output power of the lighting equipment will be limited to that limit, preventing it from reaching the higher power requested by the user. For example, the brightness of the LEDs can be limited to the level corresponding to the power limit by adjusting the current or voltage of the drive circuit. This constraint mechanism ensures that the lighting equipment will not exceed its safe operating range under any operating conditions, thereby protecting the safety of the lighting equipment itself and the power supply system.

[0044] For example, in a practical application, suppose user A uses a high-power film lighting system in a certain location. This lighting system is designed to support various power supply environments, but user A's power supply environment is a typical low-voltage AC power system, such as a power supply with a rated voltage of 110V. When the lighting system is connected to this AC power supply and powered on, the internal voltage detection module is activated, and the measured input voltage value is 108V. Subsequently, the controller of the lighting system receives this measured input voltage value of 108V. According to the internally preset rules corresponding to voltage ranges and power supply environment types, when the measured input voltage value falls within the range of 100V to 130V, the controller determines the power supply environment type as a low-voltage power supply environment.

[0045] After determining that the power supply system is in a low-voltage environment, the controller of the lighting equipment will determine the output power limit of the lighting equipment based on the type of power supply environment. For example, the lighting equipment may be configured to use a preset maximum safe power value (e.g., 1000W) as its output power limit in a low-voltage environment. This output power limit is set below the maximum power that the equipment can achieve in an ideal high-voltage environment to accommodate the carrying capacity of the low-voltage power supply circuit. After the lighting equipment is in normal operating condition, user A may attempt to set the output power of the lighting equipment to 1500W through the control panel or remote controller to obtain higher brightness. However, since the output power limit of the lighting equipment is already set to 1000W, the controller will compare the user's requested 1500W with the current 1000W output power limit. Because 1500W exceeds the 1000W limit, the controller will automatically limit the actual output power of the lighting equipment, ensuring that it can only reach a maximum of 1000W. Even if the control command requires a higher power, the lighting equipment will only operate at 1000W.

[0046] Through the above process, the lighting equipment can automatically identify its low-voltage power supply environment and dynamically adjust its maximum output power accordingly. This effectively avoids potential safety hazards such as circuit breaker tripping, power cord overheating, power supply system abnormalities, or unstable lamp operation caused by excessive power settings in low-voltage power supply environments. User A does not need to manually judge or set anything; the lighting equipment can operate stably within a safe range.

[0047] It is understood that this embodiment of the application obtains the measured input voltage value of the lighting device and determines the power supply environment type corresponding to the AC power supply based on the measured input voltage value. This enables the lighting device to automatically identify the current power supply environment without requiring any manual judgment or input from the user. This automated identification capability effectively solves the defect in the prior art where lighting devices cannot automatically sense the power supply environment. Furthermore, by determining the output power limit of the lighting device based on the power supply environment type, dynamic adjustment of the output power limit is achieved, which is in stark contrast to the prior art method of relying solely on the user to manually configure a fixed maximum power parameter. The dynamically adjusted output power limit can better adapt to the actual carrying capacity of different power supply environments, thereby significantly improving operational safety while ensuring the performance of the lighting device.

[0048] Finally, by using the output power limit as a constraint during the operation of the lighting equipment, the actual output power of the equipment is adjusted, ensuring that the equipment always operates within a safe range. This effectively avoids various safety hazards caused by power overload. This automated power management mechanism not only reduces the complexity of user operation but also fundamentally solves the safety risks caused by improper power settings in existing technologies, improving the reliability and stability of the lighting equipment in complex power supply environments.

[0049] In one possible implementation, the power supply environment type corresponding to the AC power source is determined based on the measured input voltage value, including: If the measured input voltage value is greater than the preset voltage threshold, the power supply environment type is determined to be a high-voltage power supply environment.

[0050] If the measured input voltage value is less than or equal to the preset voltage threshold, the power supply environment type is determined to be a low-voltage power supply environment.

[0051] The preset voltage threshold is a critical value used to distinguish between high-voltage and low-voltage power supply environments. This preset voltage threshold can be determined based on the design specifications of the lighting equipment, the power grid standards of the target market location, and the equipment's ability to withstand voltage fluctuations. It should be noted that this preset voltage threshold can be pre-installed in the lighting equipment's control program or adjusted through the lighting equipment's configuration interface. In this embodiment, the preset voltage threshold can be set to 180V; the specific value of this preset voltage threshold is not limited.

[0052] A high-voltage power supply environment generally refers to a power supply condition where the AC power supply voltage connected to the lighting equipment is within the normal or rated operating voltage range. A low-voltage power supply environment refers to a power supply condition where the AC power supply voltage connected to the lighting equipment is lower than the normal operating range. For example, when the preset voltage threshold is set to 180V, if the actual measured input voltage value is stable between 200V and 240V, the power supply environment type is a high-voltage power supply environment; if the actual measured input voltage value is 170V, the power supply environment type is a low-voltage power supply environment.

[0053] It should be understood that this application embodiment, by setting a preset voltage threshold, clearly classifies continuously changing measured input voltage values ​​into two types: high-voltage power supply environment and low-voltage power supply environment. When the lighting equipment is connected to AC power and powered on, the controller of the lighting equipment acquires the measured input voltage value and compares the measured input voltage value with the preset voltage threshold. If the measured input voltage value is higher than the preset voltage threshold, it is determined that the current environment is a high-voltage power supply environment; conversely, if the measured input voltage value is lower than or equal to the preset voltage threshold, it is determined that the current environment is a low-voltage power supply environment.

[0054] This threshold-based judgment mechanism provides a clear and reliable basis for determining the output power limits of lighting equipment according to the power supply environment type, thereby ensuring that the lighting equipment can perform reasonable power management under different voltage conditions. This mechanism enables the lighting equipment to intelligently adjust its operating strategy according to the actual power supply conditions, avoiding equipment damage or performance degradation caused by unstable or low voltage, and effectively improving the adaptability and reliability of the equipment.

[0055] It should also be noted that this lighting equipment has a minimum voltage protection threshold that allows it to start operating; this is the lower limit for normal low-voltage power supply environments. However, when the measured input voltage is lower than this minimum voltage protection threshold, the mains supply voltage is too low to support the power adapter module in completing voltage regulation and conversion, and to ensure the normal operation of the controller and lighting load. To prevent undervoltage from causing abnormal damage to the power chip and light source, the controller directly prevents the lighting equipment from starting and enters a standby protection state. It should be noted that this minimum voltage protection threshold can be set to 110V; the specific value of this minimum voltage protection threshold is not limited.

[0056] In one possible implementation, when the power supply environment is determined to be a high-voltage power supply environment, the output power limit of the lighting equipment is determined based on a preset rated high-voltage output power level or historical high-voltage output power level records, including: When a historical high-voltage output power level record exists, the power value corresponding to the most recently recorded historical high-voltage output power level is determined as the output power limit.

[0057] When there is no historical record of high voltage output power level, the power value corresponding to the preset rated high voltage output power level will be determined as the output power limit.

[0058] Specifically, when determining that the power supply environment type is a high-voltage power supply environment, first determine whether there are any historical high-voltage output power level records in the local area.

[0059] If no historical high-voltage output power level record exists locally, the power value corresponding to the preset rated high-voltage output power level will be used as the output power limit of the lighting device. In some examples, the preset rated high-voltage output power level can be embedded in the lighting device's firmware as the default configuration at the factory. Alternatively, in other examples, the preset rated high-voltage output power level can be stored in the lighting device's non-volatile memory (such as EEPROM or flash memory), and can be written to during the production or maintenance of the lighting device. For example, the power value corresponding to the preset rated high-voltage output power level can be as high as 3200W. In this embodiment, the power value corresponding to the preset rated high-voltage output power level is not specifically limited.

[0060] If a historical high-voltage output power level record exists locally, the power value corresponding to the most recently recorded historical high-voltage output power level will be determined as the output power limit. The most recently recorded historical high-voltage output power level is the power setting that was finally effective and saved when the lighting equipment switched to a high-voltage power supply environment and completed its operation; it is the latest high-voltage power data in the historical record. For example, if the power value corresponding to the most recently recorded historical high-voltage output power level is 1700W, then when the lighting equipment is started and the power supply environment type is determined to be a high-voltage power supply environment, 1700W will be used as the output power limit for the lighting equipment.

[0061] It should be understood that in this embodiment, the lighting equipment can intelligently and flexibly determine its output power limit based on the actual power supply environment. In low-voltage power supply environments, users can independently select the power level according to their actual needs, greatly improving user experience and equipment applicability. This avoids equipment malfunction or damage caused by fixed high power output when the power supply is unstable, while also meeting users' energy-saving needs in specific scenarios. In high-voltage power supply environments, the output power limit is automatically determined based on a preset rated high-voltage output power level or historical high-voltage output power level records. This ensures optimal performance output and operational safety of the lighting equipment under stable high-voltage power supply conditions, avoiding equipment overload or inefficiency due to user error. This differentiated power limit determination mechanism enables the lighting equipment to achieve optimal power management under different power supply conditions, significantly improving the reliability, safety, and user satisfaction of the lighting equipment.

[0062] In one possible implementation, when the power supply environment type is determined to be a low-voltage power supply environment, the power value corresponding to the target power level selected by the user in the power selection interface is determined as the output power limit of the lighting equipment, including: When the power supply environment is a low-voltage power supply environment, the power value corresponding to the low-voltage default power level is used as the temporary output power limit of the lighting equipment, and the power selection interface is displayed.

[0063] In response to the target power level selected by the user on the power selection interface, the current output power limit is updated to the power value corresponding to the target power level, and the power selection interface is closed.

[0064] When the power supply environment is determined to be a low-voltage environment, the lighting equipment automatically enters the power selection process. This means it automatically operates with the power value corresponding to the low-voltage default power level as the temporary output power limit, and simultaneously triggers the power selection interface. The low-voltage default power level can be understood as an initial power level automatically applied when the lighting equipment detects a low-voltage power supply environment. This low-voltage default power level is typically preset to a low or medium safe power value to ensure stable and safe operation of the lighting equipment before explicit user selection, and to avoid impacting the lighting equipment or power supply system due to excessively high initial power. The power value corresponding to this low-voltage default power level can be fixed in the firmware at the factory as an unchangeable default value; alternatively, it can be configured and modified by users or maintenance personnel through a specific maintenance interface to adapt to different application scenarios. In this embodiment, the setting method and specific value of the power value corresponding to the low-voltage default power level are not limited.

[0065] The temporary output power limit can be understood as the upper limit of output power temporarily enabled under low-voltage power supply conditions before manual selection by the user. It serves as a transitional restriction before the user performs further operations. This temporary output power limit provides the lighting equipment with an immediately available operating parameter, while also offering the user the opportunity to select and adjust it.

[0066] The power selection interface is a graphical user interface (GUI) or physical interface that allows users to view and select from available power level options. This interface provides an interactive entry point for users to adjust the output power of the lighting equipment according to their actual needs. The power level options provided on this interface may include one option with a power value of 1700W and a current value of 15A, and another option with a power value of 2200W and a current value of 20A. This power selection interface can be displayed on the lighting equipment's built-in display screen, or it can be displayed on the display screen of a client device connected to the lighting equipment (such as a mobile app, remote control, etc.). Figure 2 As shown, Figure 2This is a schematic diagram of a power selection interface provided in an embodiment of this application. The power selection interface will pop up and display when the power supply environment is detected to be a low-voltage power supply environment when the lighting equipment is powered on.

[0067] When the lighting equipment detects a low-voltage power supply environment, it first sets a preset power level corresponding to a low-voltage default power level as a temporary output power limit. This ensures that the lighting equipment can operate at a safe and expected power level even before the user makes a specific power selection. Simultaneously, the lighting equipment proactively displays a power selection interface to the user, offering multiple selectable power levels.

[0068] Once the system detects that a user has performed a selection operation (such as clicking, touching, or pressing a button) on the power selection interface, meaning the user has selected a target power level, the controller of the lighting equipment will immediately respond to the user's selection and update the current output power limit to the power value corresponding to the user's selected target power level. Simultaneously, after the user completes the power selection and updates the output power limit, the controller of the lighting equipment will automatically close the power selection interface to maintain its simplicity and operational consistency.

[0069] Through this series of steps, this embodiment can effectively solve the problem of connecting the initial power setting of lighting equipment with user interaction selection in a low-voltage power supply environment, ensuring that the lighting equipment has a clear power limit at all times, and providing flexible user customization capabilities.

[0070] In one possible implementation, the method includes: If no user selects a target power level on the power selection interface while the power selection interface is displayed and not closed, the temporary output power limit will be maintained as the output power limit, and the power selection interface will remain displayed.

[0071] Furthermore, while the power selection interface is displayed and not closed, if no user operation is received to select a target power level on the power selection interface, that is, if the user is detected not to have performed any interactive behavior on the power selection interface, the lighting equipment will continue to use the temporary output power limit (i.e., the power value corresponding to the low-voltage default power level) as the output power limit of the lighting equipment. At the same time, the power selection interface will remain displayed to provide the user with continuous interaction opportunities.

[0072] It should be understood that this mechanism ensures stable operation of the lighting equipment even when the user is temporarily distracted or needs more time to consider the issue, and the user can return to the interface at any time to select power without having to re-trigger or search for the interface. This coordinated action makes the user experience of the lighting equipment smoother and more fault-tolerant in low-voltage power supply environments.

[0073] In one possible implementation, the method includes: The power selection interface is displayed synchronously on both the local end of the lighting equipment and the client that communicates with the lighting equipment.

[0074] After the user selects the target power level in the local power selection interface, the output power limit is updated and the local power selection interface is closed. Simultaneously, the client-side power selection interface automatically closes. Alternatively, After the user selects the target power level on the client's power selection interface, the output power limit is updated and the client's power selection interface is closed. At the same time, the local power selection interface is automatically closed.

[0075] In this context, the local end of the lighting equipment refers to the control interface or display screen integrated into the lighting equipment itself, allowing users to operate it directly. The client refers to the external terminal device that establishes a communication connection with the lighting equipment, such as a smartphone, tablet, or personal computer. The client interacts with the lighting equipment via wireless communication (such as Wi-Fi or Bluetooth) or wired communication, and provides a graphical user interface for remote operation.

[0076] In some examples, when the client and the lighting device are connected, when the lighting device enters the power selection mode, the user can see the same power selection interface on both the local device and the client. This can be achieved by the local device sending an interface status synchronization command to the client or by the client actively querying the local device status and rendering the interface.

[0077] In some examples, after a user completes the power level selection through the local power selection interface, the lighting device controller will immediately update the output power limit and close the local power selection interface. At the same time, the controller will send an interface shutdown command to the connected client so that the power selection interface on the client will also be automatically closed, ensuring consistency between local and client operations.

[0078] In some examples, after a user selects a power level through the client's power selection interface, the client closes the interface and sends the selection information to the lighting device. Upon receiving this information, the lighting device updates its output power limit. Simultaneously, the local power selection interface also closes automatically, achieving synchronized response across platforms.

[0079] In short, if the client and the lighting equipment are in a communication connection, the corresponding power selection interface will be displayed synchronously on both the local end of the lighting equipment and the client. Power selection settings can be made on both the local end and the client, and after the power selection settings are completed on either end, the power selection interface on both the local end and the client will close simultaneously.

[0080] It should be understood that in this embodiment, by synchronously displaying the power selection interface on both the local end of the lighting device and the client that has established a communication connection with the lighting device, a consistent visual feedback is ensured regardless of how the user operates. When the user selects a target power level on either interface, the lighting device immediately updates its output power limit. More importantly, after completing the power selection operation, both the local and client-side power selection interfaces automatically close. This mechanism avoids confusion caused by inconsistent interface states when operating across multiple devices, ensuring the uniqueness and finality of the operation. In this way, the lighting device can function as a whole, coordinating local and remote control, providing a seamless and efficient user experience, and effectively solving the problems of state synchronization and operational consistency across multiple control interfaces.

[0081] In one possible implementation, after determining that the power supply environment type is a low-voltage power supply environment and setting the power value corresponding to the target power level selected by the user in the power selection interface as the output power limit of the lighting equipment, the method further includes: In response to the user's power modification command, a power selection interface is displayed so that the user can reselect the target power level on the power selection interface.

[0082] In low-voltage power supply environments, users can adjust the preset output power limits of the lighting equipment during operation, based on changes in the actual application scenario or personal preferences. A power modification command refers to an operation signal actively issued by the user to adjust the current output power limit of the lighting equipment. This power modification command can be triggered in various ways, such as by the user operating physical buttons on the lighting equipment, or by sending a command through a remote client connected to the lighting equipment.

[0083] After receiving a power modification command from the user, the lighting equipment or a client connected to the lighting equipment displays the power selection interface to the user, allowing the user to reselect a desired power level. This process is similar to setting the power level for the first time, but it occurs after the lighting equipment has already determined its initial output power limit. The user can set the power value corresponding to the newly selected power level as the output power limit of the lighting equipment through interactive methods such as clicking. Furthermore, after the user sets the power level, the power selection interface will display options to confirm the power and save the settings for further confirmation.

[0084] It should be understood that this design frees users from the initial output power limit setting. Instead, users can flexibly adjust the output power limit of the lighting equipment at any time according to changes in the actual usage scenario, such as adjusting the ambient light during shooting, energy-saving needs, or artistic effects. This greatly improves the adaptability of the equipment and the ease of user operation. In this way, even after the equipment has automatically or initially set a power limit based on the power supply environment, users can still modify the equipment's output power, ensuring that the lighting equipment can better meet diverse usage needs.

[0085] In one possible implementation, after determining the power value corresponding to the most recently recorded historical high-voltage output power level as the output power limit when historical high-voltage output power level records exist, the method further includes: If the output power limit is lower than the preset power threshold, a prompt message will be displayed to the user. The prompt message indicates that the current output power limit of the lighting equipment is too low, and the output power limit can be adjusted upward according to the user's needs.

[0086] The preset power threshold refers to the reference power base value stored in the lighting equipment. This preset power threshold is lower than the power value corresponding to the preset rated high-voltage output power level, and is used to determine whether the currently set upper limit of output power has an upward adjustment margin. Typically, in a high-voltage power supply environment, the power output range of lighting equipment is usually 700W-3200W. When the current output power limit of the lighting equipment is lower than the preset power threshold, such as when the preset power threshold is 1500W and the current output power limit is set to 1000W, the lighting equipment will display a pop-up window to show the user a prompt message.

[0087] The notification message refers to a text or icon pop-up notification window that appears on the local end or client side of the lighting equipment. It is a type of human-computer interaction notification. The content of this notification message is to inform the user that the current power limit is far from the reasonable power range that can be carried out under high voltage conditions, and that the power performance of the equipment is limited. It also informs the user that they can manually increase the power output level and increase the brightness and power of the lights in the background to match the on-site usage needs.

[0088] It should be understood that the method provided in this embodiment allows users to promptly understand potential power underutilization issues of lighting equipment under high-voltage power supply environments, thus providing an opportunity to adjust power settings and fully utilize the performance potential of the lighting equipment. In this way, this embodiment not only ensures the stable operation of the lighting equipment under different power supply environments, but also guides users to optimize power settings under high-voltage environments through an intelligent prompting mechanism, avoiding performance waste caused by improper user operation or insufficient understanding, thereby improving lighting effects and energy efficiency.

[0089] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
