[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0030] It should be noted that the terms "first", "second", "target", and "original" in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0031] Figure 1 It is a flow chart of the power adjustment method of the lighting device provided in the embodiment of the present application. The present embodiment can be applied to the scenario where the power of the lighting device needs to be adjusted without affecting the user's perceived brightness. The power adjustment method of the lighting device provided in the present embodiment can be executed by the power adjustment device of the lighting device provided in the embodiment of the present application, and the device can be implemented by software and / or hardware. In a specific embodiment, the power adjustment device of the lighting device can be integrated in an electronic device, and the electronic device can be a computer, etc., which can control the lighting device. The execution subject of this method can be an electronic device, see Figure 1 The power adjustment method of the lighting device of this embodiment includes but is not limited to the following steps:

[0032] S110. Obtain current status data of the lighting device.

[0033] Among them, lighting equipment is a device used to generate light to illuminate an environment or an object; illustratively, the lighting equipment may include office lamps, street lamps, landscape lamps, etc.

[0034] The current status data is the operating status and performance parameter information of the lighting equipment at the current moment, reflecting the working status and performance of the lighting equipment; the current status data may include current power, current perceived brightness, current light source efficiency and current lighting area; among them, the current power is the power actually consumed by the lighting equipment at the current moment; the current perceived brightness is the brightness perceived by the human eye for the light emitted by the lighting equipment at the current moment; the current light source efficiency is the luminous flux emitted by the lighting equipment per unit power consumed, reflecting the ability of the lighting equipment to convert electrical energy into light energy at the current moment; the luminous flux is the radiation power that can be felt by the human eye; the current lighting area is the area that can be illuminated by the lighting equipment at the current moment.

[0035] Specifically, when it is necessary to adjust the power of the lighting equipment, the current status data of the lighting equipment can be obtained, that is, the current power, current perceived brightness, current light source efficiency and current lighting area of ​​the lighting equipment and other status data can be collected in real time through intelligent sensors. For example, a power meter can be used to measure the input power of the lighting equipment to obtain the current power; a light meter can be used to measure the light intensity under the lighting equipment or at a specified position, and the current perceived brightness can be calculated based on the lighting distance and light source characteristics, combined with the human eye's perception range of brightness; the luminous flux of the lighting equipment can be measured by a light meter, and then the current light source efficiency can be calculated based on the luminous flux and the current power obtained as mentioned above; a light meter can be used to measure the light intensity of the lighting equipment in different directions, and then the current lighting area can be calculated based on the lighting distance, light emitting angle and lighting requirements (such as lighting intensity and lighting uniformity).

[0036] S120: Determine the minimum brightness of the lighting device while keeping the current perceived brightness unchanged.

[0037] Among them, the minimum brightness is the lowest brightness level that the lighting equipment can reach while keeping the current perceived brightness (i.e. the brightness comfort perceived by people) unchanged; by adjusting the brightness of the lighting equipment, energy consumption can be reduced while ensuring comfort and visibility.

[0038] Specifically, after obtaining the current state data, the minimum brightness of the lighting device when the current perceived brightness is kept unchanged can be determined. For example, multiple color temperature parameter values ​​corresponding to the current perceived brightness can be determined based on the current perceived brightness. At this time, the perceived brightness corresponding to the multiple color temperature parameter values ​​is the same. Then, the brightness value corresponding to each color temperature parameter value in the multiple color temperature parameter values ​​is calculated to obtain multiple brightness values, and the minimum value is selected from the multiple brightness values ​​to obtain the minimum brightness. At the same time, the color temperature parameter value corresponding to the minimum brightness is determined as the optimal color temperature parameter, and the optimal color temperature parameter is recorded. Among them, the color temperature parameter is a physical quantity that describes the color attribute of the light source.

[0039] S130: Determine the optimal power according to the minimum brightness, the current light source efficiency and the current lighting area.

[0040] Among them, the optimal power is the power value at which the lighting equipment should operate under the premise of meeting the lighting needs and energy-saving requirements. It can be determined by comprehensively considering the minimum brightness, current light source efficiency and current lighting area, aiming to achieve the best balance between lighting effect and energy consumption.

[0041] Specifically, after obtaining the minimum brightness, the optimal power can be determined based on the minimum brightness, the current light source efficiency and the current lighting area. For example, the optimal luminous flux can be determined based on the minimum brightness and the current lighting area, and then the optimal power can be further determined based on the optimal luminous flux and the current light source efficiency.

[0042] S140: Determine a power optimization amount of the lighting device according to the optimal power and the current power.

[0043] The power optimization amount is the amount of power that needs to be adjusted for the current power of the lighting device in order to achieve the optimal power, that is, the difference between the optimal power and the current power.

[0044] Specifically, after obtaining the optimal power, the power optimization amount of the lighting device can be determined according to the optimal power and the current power, that is, the difference between the optimal power and the current power can be calculated to obtain the power optimization amount of the lighting device.

[0045] It should be noted that if the optimal power is greater than the current power, the power optimization amount is a positive value, indicating that the power needs to be increased; if the optimal power is less than the current power, the power optimization amount is a negative value, indicating that the power needs to be reduced; if the optimal power is equal to the current power, the power optimization amount is 0, indicating that there is no need to adjust the power, and the current power at this time is the optimal power. In order to reduce the user's power load and improve energy utilization, the power optimization amount in the embodiment of the present application is a negative value.

[0046] S150: Adjust the current power of the lighting device according to the power optimization amount of the lighting device.

[0047] Specifically, after obtaining the power optimization amount, the current power of the lighting device can be adjusted according to the power optimization amount of the lighting device. For example, a power adjustment instruction can be generated based on the power optimization amount of the lighting device. The power adjustment instruction at this time includes the power optimization amount. Then the power adjustment instruction is executed. For example, when the power optimization amount is a negative value, the current power is reduced based on the power optimization amount so that the current power of the lighting device is adjusted to the optimal power.

[0048] In another implementation, the power adjustment instruction may include optimal state data, namely, optimal color temperature parameters and minimum brightness. At this time, a state adjustment instruction can be generated based on the optimal color temperature parameters and minimum brightness, and the state adjustment instruction can be executed. For example, the color temperature parameter value of the lighting device at the current moment is adjusted to the optimal color temperature parameter, and the brightness of the lighting device at the current moment is adjusted to the minimum brightness, so that the current power of the lighting device is adjusted to the optimal power.

[0049] The technical solution of the embodiment of the present application can obtain the current status data of the lighting device, and determine the minimum brightness of the lighting device while keeping the current perceived brightness unchanged, and then determine the optimal power based on the minimum brightness, the current light source efficiency and the current lighting area, and determine the power optimization amount of the lighting device based on the optimal power and the current power, and then adjust the current power of the lighting device based on the power optimization amount of the lighting device, thereby realizing the power adjustment function of the lighting device. In the above technical scheme, by determining the minimum brightness of the lighting device while keeping the current perceived brightness unchanged, it is possible to ensure that the perceived brightness corresponding to the minimum brightness is the same as the current perceived brightness, and further determine the optimal power based on the minimum brightness, so that the perceived brightness corresponding to the optimal power is the same as the current perceived brightness, thereby solving the problem in the prior art that the user can perceive the brightness change of the lighting device when adjusting the power consumption on the user side, and avoiding the discomfort caused to the user by sudden changes in brightness, thereby improving the user experience; at the same time, on the premise of ensuring that the current perceived brightness remains unchanged, the power optimization amount is determined based on the optimal power and the current power, and the power of the lighting device is adjusted based on the power optimization amount, which can reduce the energy consumption of the lighting device while keeping the current perceived brightness unchanged, and by precisely controlling the power of the lighting device, it can reduce the load fluctuation of the power system, thereby improving the stability of the power system.

[0050] The following further describes a power adjustment method for a lighting device provided by an embodiment of the present application. Figure 2 1 is another flow chart of the power adjustment method for lighting equipment provided by the embodiment of the present application. The embodiment of the present application is optimized on the basis of the above embodiments. Figure 2 The method of this embodiment includes but is not limited to the following steps:

[0051] S210: Obtain current status data of the lighting device.

[0052] Specifically, the implementation process and technical principle of S210 are the same as those of S110, and reference may be made to the description of S110 above, which will not be repeated here.

[0053] S220: Determine multiple candidate color temperature parameter values ​​according to the current perceived brightness.

[0054] The candidate color temperature parameter values ​​are light source color temperature values ​​that may be selected while keeping the current perceived brightness unchanged, and the perceived brightness corresponding to the multiple candidate color temperature parameter values ​​is the same.

[0055] Specifically, after obtaining the current state data, multiple candidate color temperature parameter values ​​can be determined according to the current somatosensory brightness, that is, the color temperature adjustment range corresponding to the current somatosensory brightness can be determined based on the preset brightness-color temperature relationship, and the color temperature parameter value can be selected from the color temperature adjustment range to obtain multiple candidate color temperature parameter values. Among them, the preset brightness-color temperature relationship is a pre-set relationship table for storing the mapping relationship between somatosensory brightness and color temperature adjustment range; the preset brightness-color temperature relationship includes multiple somatosensory brightnesses and the color temperature adjustment range corresponding to each somatosensory brightness, that is, one color temperature adjustment range corresponds to one somatosensory brightness; the somatosensory brightness corresponding to each color temperature parameter value included in the color temperature adjustment range is the same, that is, the color temperature adjustment range is the color temperature parameter value range corresponding to the same somatosensory brightness.

[0056] Specifically, the preset brightness-color temperature relationship can be queried based on the current perceived brightness to obtain the color temperature adjustment range corresponding to the current perceived brightness, and then each color temperature parameter value in the color temperature adjustment range is determined as a candidate color temperature parameter value to obtain multiple candidate color temperature parameter values, and the perceived brightness corresponding to the multiple candidate color temperature parameter values ​​is the same.

[0057] S230: Determine a maximum color temperature influence coefficient according to a plurality of candidate color temperature parameter values.

[0058] Among them, the maximum color temperature influence coefficient is the maximum value of the color temperature influence coefficients corresponding to multiple candidate color temperature parameter values; the color temperature influence coefficient is used to reflect the relative influence of a certain color temperature parameter value on the visual perception of the human eye under the premise of keeping the perceived brightness unchanged; the larger the color temperature influence coefficient, the stronger the visual stimulation of the color temperature parameter value to the human eye; the smaller the color temperature influence coefficient, the weaker the visual stimulation of the color temperature parameter value to the human eye.

[0059] Specifically, the maximum color temperature influence coefficient is determined according to a plurality of candidate color temperature parameter values, including Sa1-Sa2:

[0060] Sa1. Based on the visibility function, calculate a color temperature influence coefficient corresponding to each candidate color temperature parameter value among multiple candidate color temperature parameter values.

[0061] Among them, the viewing function describes the sensitivity of the human eye to light of different wavelengths under bright conditions. It is used to convert physical radiant energy into visually equivalent radiant energy in order to more accurately evaluate the impact of the brightness and color of the light source on human vision.

[0062] Alternatively, the visibility function can be expressed as:

[0063]

[0064] Wherein, V(λ) represents the viewing efficiency, that is, the output value of the viewing function, which is used to describe the sensitivity of the human eye to light of different wavelengths; λ represents the wavelength in nanometers (nm).

[0065] Specifically, after obtaining a plurality of candidate color temperature parameter values, any candidate color temperature parameter value may be selected from the plurality of candidate color temperature parameter values ​​as the current candidate color temperature parameter value, and then the visible wavelength range of the spectral distribution of the current candidate color temperature parameter value is determined to obtain the current wavelength range, that is, the wavelength range that can be perceived by the human eye, and the current wavelength range is sampled based on a preset wavelength interval to obtain a plurality of discrete wavelengths, that is, a plurality of candidate wavelengths corresponding to the current candidate color temperature parameter value, and then the spectral distribution data of the light source is searched for each of the plurality of candidate wavelengths to obtain the spectral radiation intensity corresponding to each candidate wavelength, and each of the plurality of candidate wavelengths is input into the visibility function to obtain the visibility efficiency corresponding to each candidate wavelength, and then, for each of the plurality of candidate wavelengths, the product of the spectral radiation intensity of each candidate wavelength and the corresponding visibility efficiency is calculated to obtain the product corresponding to each candidate wavelength, and the sum of the aforementioned products is calculated to obtain the weighted radiant power corresponding to the current candidate color temperature parameter value; and then, other candidate color temperature parameter values ​​may be selected as the current candidate color temperature parameter value, and the above steps are repeated to obtain the weighted radiant power corresponding to each candidate color temperature parameter value. The spectral distribution data is the distribution of the radiation intensity or power of the light emitted by the light source at different wavelengths. The preset wavelength interval is a pre-set value for sampling the wavelength range. The user can adjust and set the preset wavelength interval according to actual usage requirements, and the embodiments of the present application do not specifically limit this.

[0066] Afterwards, the ratio of the weighted radiant power of each candidate color temperature parameter value to the sum of the weighted radiant powers of all candidate color temperature parameter values ​​is calculated respectively to obtain the color temperature influence coefficient corresponding to each candidate color temperature parameter value.

[0067] Sa2. Determine a maximum value from the color temperature influence coefficients corresponding to each candidate color temperature parameter value to obtain a maximum color temperature influence coefficient.

[0068] Specifically, after obtaining the color temperature influence coefficient corresponding to each candidate color temperature parameter value, the multiple color temperature influence coefficients may be sorted, and the maximum value of the color temperature influence coefficients may be determined therefrom, and then the maximum value may be determined as the maximum color temperature influence coefficient.

[0069] In the embodiment of the present application, the color temperature influence coefficient of each candidate color temperature parameter value is determined according to the viewing function, which can more accurately reflect the sensitivity of the human eye to different color temperatures, thereby improving the accuracy and efficiency of determining the color temperature influence coefficient, and further determining the maximum value of the color temperature influence coefficient as the maximum color temperature influence coefficient, thereby realizing the determination function of the maximum color temperature influence coefficient, and the color temperature corresponding to the maximum color temperature influence coefficient is most in line with the visual habits of the human eye, providing data support for the subsequent determination of the minimum brightness.

[0070] S240: Determine the minimum brightness according to the maximum color temperature influence coefficient and the current body perception brightness.

[0071] Specifically, after obtaining the maximum color temperature influence coefficient, the minimum brightness can be determined according to the maximum color temperature influence coefficient and the current perceived brightness, that is, the ratio between the current perceived brightness and the maximum color temperature influence coefficient can be calculated and determined as the minimum brightness.

[0072] S250: Determine the minimum luminous flux according to the minimum brightness and the current lighting area.

[0073] Among them, the minimum luminous flux is the luminous flux required to achieve the minimum brightness and cover the current lighting area to ensure that the lighting effect meets the requirements.

[0074] Specifically, after the minimum brightness is obtained, the minimum luminous flux can be determined according to the minimum brightness and the current lighting area, that is, the product between the minimum brightness and the current lighting area can be calculated and the product can be determined as the minimum luminous flux.

[0075] S260: Determine the optimal power according to the minimum luminous flux and the current light source efficiency.

[0076] Specifically, after the minimum luminous flux is obtained, the optimal power can be determined according to the minimum luminous flux and the current light source efficiency, that is, the product between the minimum luminous flux and the current light source efficiency can be calculated and the product can be determined as the optimal power.

[0077] S270: Calculate the difference between the optimal power and the current power to obtain the power optimization amount of the lighting equipment.

[0078] Specifically, after obtaining the current power, the difference between the optimal power and the current power may be calculated, and the difference may be determined as the power optimization amount of the lighting device.

[0079] Optionally, after determining the power optimization amount of the lighting equipment based on the optimal power and the current power, it may also include: determining the power declaration amount based on the power optimization amount of the lighting equipment; and sending the power declaration amount to the virtual power plant system so that the virtual power plant system determines the reward value of the lighting equipment based on the power declaration amount.

[0080] The power declaration is determined based on the power optimization of the lighting equipment and is the power adjustment amount that needs to be reported to the virtual power plant system. It reflects the power amount that the lighting equipment plans to reduce or increase in the future. The virtual power plant system can optimize the energy distribution and scheduling of the entire power grid by collecting and managing the power declarations of various distributed energy devices.

[0081] The virtual power plant system is a bridge between the power grid management center, distributed energy, and user-adjustable resources. It optimizes the management of the power system by integrating multiple energy resources, such as wind energy, solar energy, and energy storage equipment. Electronic devices can communicate with the virtual power plant system, and the communication protocol used can be the Message Queuing Telemetry Transport (MQTT) protocol.

[0082] The reward value is an economic or other form of incentive given by the virtual power plant system based on the power declaration submitted by the lighting equipment; the virtual power plant system encourages distributed energy devices involved in power regulation to actively participate in the energy management and scheduling of the power grid; for example, the reward value may include economic rewards and point rewards, etc., depending on the operating strategy and policy of the virtual power plant system.

[0083] Specifically, when a user has a lighting device, after obtaining the power optimization amount of the lighting device, the power optimization amount of the lighting device can be determined as the power declaration amount, and the power declaration amount can be sent to the virtual power plant system; after that, the virtual power plant system can determine the reward value of the lighting device according to the power declaration amount, that is, the virtual power plant system can declare electricity to the power trading agency based on the power declaration amount, and then after the power declaration is successful, determine the reward value corresponding to the power declaration amount based on the preset reward rules, and reward the user based on the reward value to encourage the user to continue to participate in the operation and power optimization activities of the virtual power plant system. Among them, the preset reward rules are rules predetermined based on the reward policy of the virtual power plant system, which can convert the power declaration amount into the corresponding reward value.

[0084] In an embodiment of the present application, the power declaration amount is determined by the power optimization amount, so that the virtual power plant system can more accurately match the power demand and power supply of the lighting equipment, thereby enhancing the stability of the power grid; and the reward value of the lighting equipment is determined based on the power declaration amount, which provides economic incentives for users and can encourage users to participate in the regulation and optimization of the electricity market, thereby reducing energy waste and promoting efficient use of energy.

[0085] Optionally, there are multiple lighting devices. After determining the power optimization amount of the lighting device based on the optimal power and the current power, it can also include: determining the total power declaration amount based on the power optimization amount of each lighting device among the multiple lighting devices; sending the total power declaration amount to the virtual power plant system, so that the virtual power plant system determines the total reward value of the multiple lighting devices based on the total power declaration amount.

[0086] The total power declared is the total power adjustment amount that needs to be reported to the virtual power plant system, which is determined based on the power optimization amount of multiple lighting devices, and reflects the total power that multiple lighting devices plan to reduce or increase in the future. The total reward value is the economic or other forms of incentives given by the virtual power plant system based on the total power declared by multiple lighting devices.

[0087] Specifically, when a user has multiple lighting devices, after obtaining the power optimization amount of each of the multiple lighting devices, the sum of the power optimization amounts of the multiple lighting devices can be calculated to obtain the total power declaration amount, and the total power declaration amount can be sent to the virtual power plant system; thereafter, the virtual power plant system can determine the total reward value of the multiple lighting devices based on the total power declaration amount, that is, the virtual power plant system can declare electricity to the power trading agency based on the total power declaration amount, and then after the electricity declaration is successful, determine the total reward value corresponding to the total power declaration amount based on the preset reward rules, and reward the user based on the total reward value to encourage the user to continue to participate in the operation of the virtual power plant system and power optimization activities.

[0088] In an embodiment of the present application, the total power declaration amount is determined by the power optimization amount of multiple lighting devices, so that the virtual power plant system can more accurately match the power demand and power supply of multiple lighting devices, thereby enhancing the stability of the power grid; and the total reward value of the lighting equipment is determined based on the total power declaration amount, which provides economic incentives for users and can encourage users to participate in the regulation and optimization of the electricity market, thereby reducing energy waste and promoting efficient use of energy.

[0089] S280: Adjust the current power of the lighting device according to the power optimization amount of the lighting device.

[0090] Specifically, when a user has a lighting device, after obtaining the power optimization amount of the lighting device, the electronic device can determine the power declaration amount based on the power optimization amount of the lighting device, and send the power declaration amount to the virtual power plant system; then, the virtual power plant system can declare electricity based on the power declaration amount, and then after the electricity declaration is successful, generate a power adjustment instruction based on the power declaration amount, and send the power adjustment instruction to the electronic device; thereafter, the electronic device can receive the power adjustment instruction and execute the power adjustment instruction to adjust the current power of the lighting device based on the power optimization amount of the lighting device.

[0091] When a user has multiple lighting devices, after obtaining the power optimization amount of each of the multiple lighting devices, the electronic device can calculate the sum of the power optimization amounts of the multiple lighting devices, obtain the total power declaration amount, and send the total power declaration amount to the virtual power plant system; then, the virtual power plant system can declare electricity based on the received total power declaration amount, and then after the electricity declaration is successful, generate a total power adjustment instruction based on the total power declaration amount, and send the total power adjustment instruction to the electronic device; thereafter, the electronic device can receive the total power adjustment instruction and execute the total power adjustment instruction to adjust the current power of the corresponding lighting device based on multiple power optimization amounts.

[0092] The technical solution improved by the embodiment of the present application can obtain the current state data of the lighting device, and determine multiple candidate color temperature parameter values ​​according to the current perceived brightness, then determine the maximum color temperature influence coefficient according to the multiple candidate color temperature parameter values, and determine the minimum brightness according to the maximum color temperature influence coefficient and the current perceived brightness, thereby realizing the function of determining the minimum brightness, determining the maximum color temperature influence coefficient through multiple candidate color temperature parameter values, and further determining the minimum brightness according to the maximum color temperature influence coefficient, thereby improving the accuracy and efficiency of determining the minimum brightness, and providing data support for the subsequent determination of the optimal power; then, the minimum luminous flux can be determined according to the minimum brightness and the current lighting area, thereby ensuring that the light emitted by the lighting device The line intensity is sufficient to meet specific lighting needs, and the optimal power is determined according to the minimum luminous flux and the current light source efficiency, realizing the optimal power determination function, improving the accuracy and efficiency of the optimal power determination, and providing data support for the subsequent determination of the power optimization amount; after that, the difference between the optimal power and the current power can be calculated to obtain the power optimization amount of the lighting equipment, and the current power of the lighting equipment can be adjusted according to the power optimization amount of the lighting equipment, which can reduce the energy consumption of the lighting equipment while keeping the current perceived brightness unchanged, and by precisely controlling the power of the lighting equipment, the load fluctuation of the power system can be reduced, thereby improving the energy utilization efficiency and the stability of the power system.
