[0002] Lighting effect refers to the creation of a variety of visual effects by adjusting the brightness, color, mode, etc. of the light to adapt to different scenes and atmosphere requirements. Lighting effect not only plays an important role in home decoration, but is also widely used in public spaces such as entertainment venues and shopping malls. However, in actual applications, the current of the lamp is not always constant, but will fluctuate due to external factors, such as electromagnetic interference in the driving circuit and fluctuations in the grid voltage. As a result, the lighting effect will also change. Lighting effect control is to accurately adjust and manage various parameters of the light through an intelligent system. With the development of LED technology and the popularization of smart lamps, lighting effect control is gradually moving towards digitalization and intelligence, using wireless communication, sensing technology, algorithm optimization and other means to make lighting effect control more precise, convenient and diversified.

Secondly, the lighting effect control method in the existing technology does not take into account the current change law of the lamp in different time periods, and it is difficult to make fine adjustments based on the operating data of the lamp, resulting in unstable lighting effects. Finally, the existing technology has a relatively simple adjustment of the lighting effect. Under different areas and different usage requirements, the lighting effect performance of the lamp is difficult to adjust according to the real-time operating environment data, and the control method of the existing technology is difficult to cope with the complex actual use environment and changing lighting needs, and cannot achieve the expected lighting effect and energy efficiency.

[0018] (2) This lighting control method obtains environmental data such as ambient light intensity and ambient color temperature in real time, and makes dynamic adjustments based on a regression model, so that the lamp can automatically optimize the color temperature, brightness and color rendering effect according to real-time environmental changes, thereby ensuring that the lamp can always provide the expected light quality, thereby adapting to changes in different time periods and environmental conditions, and then improving the light environment quality of the overall space.

[0025] The embodiments of the present application solve the problems in the prior art that the prior art lacks dynamic feedback and adjustment of the actual use environment and the operating status of the lamp through a lighting effect control method and system, and it is difficult to take into account the environmental changes of the lamp during the actual operation, such as the real-time impact of factors such as current fluctuations on the performance of the lamp, resulting in the performance of the lamp may not achieve the expected effect, thereby affecting the use experience and energy efficiency. Secondly, the lighting effect control method in the prior art does not take into account the current change law of the lamp in different time periods, and it is difficult to make fine adjustments based on the operating data of the lamp, resulting in unstable lighting effects. Finally, the prior art has a relatively simple adjustment of the lighting effect. Under different areas and different usage requirements, the lighting effect performance of the lamp is difficult to adjust based on the real-time operating environment data, and the control method of the prior art is difficult to cope with the complex actual use environment and changing lighting requirements, and cannot achieve the expected lighting effect and energy efficiency.

[0026] The overall idea of ​​the problem in the embodiment of this application is as follows:

[0027] First, the previous lighting effect operation status data of the lamps to be controlled in the set area for several previous time periods are obtained, and then the multiple regression model is used to perform predictive analysis on the previous lighting effect operation status data to obtain a regression coefficient set, and the operating environment data and real-time lighting effect operation status data of the lamps to be controlled in the set area are obtained in real time, and then data analysis is performed to obtain the real-time color temperature control amount, real-time brightness control amount, and real-time color rendering control amount of the lamps to be controlled in the set area, and a comprehensive analysis is performed in combination with the regression coefficient set to obtain the real-time current control amount, and then it is determined whether the current current control amount is within a preset current control threshold range. If it is within the threshold, no control is performed; if it is outside the threshold, the lighting effect is optimized by adjusting the current.

[0028] See also Figure 1The embodiment of the present invention provides a technical solution: a lighting effect control method, comprising the following steps: obtaining previous lighting effect operation status data of several previous time periods of the lamps to be controlled (such as LEDs) in a set area (such as a museum); using a multivariate regression model to predict and analyze the previous lighting effect operation status data of several previous time periods (in this embodiment, the previous time period is the time between the change in current and the next change in current) of the lamps to be controlled in the set area to obtain a regression coefficient set; and obtaining real-time operating environment data and real-time lighting effect operation status data of the lamps to be controlled in the set area in real time, and performing data analysis to obtain real-time color temperature control amount, real-time brightness control amount, and real-time color rendering control amount of the lamps to be controlled in the set area; comprehensively analyzing the regression coefficient set with the real-time color temperature control amount, real-time brightness control amount, and real-time color rendering control amount of the lamps to be controlled in the set area to obtain Control the real-time current regulation amount of the lamp; read the real-time operating current value in the real-time lighting effect operating status data of the lamp to be controlled in the set area, and judge and analyze the real-time current regulation amount of the lamp to be controlled in the set area and the preset current regulation amount threshold range; if the real-time current regulation amount of the lamp to be controlled in the set area is within the preset current regulation amount threshold range, the real-time operating current value of the lamp to be controlled in the set area is not regulated (and the data analysis, comprehensive analysis, and judgment analysis steps are repeated for the next real-time operating environment data obtained in real time); if the real-time current regulation amount of the lamp to be controlled in the set area is outside the preset current regulation amount threshold range, the real-time operating current value is regulated based on the real-time current regulation amount of the lamp to be controlled in the set area (because the operating current value will affect the color rendering value, color temperature value, and brightness value of the lamp, so the real-time operating current value can be directly regulated).

[0029] The previous lighting effect operation status data includes the previous color rendering value, the previous color temperature value, the previous brightness value, and the previous operating current value. The regression coefficient set includes the color temperature regression coefficient, the brightness regression coefficient, and the color rendering regression coefficient. The real-time lighting effect operation status data includes the real-time color rendering value, the real-time color temperature value, the real-time brightness value, and the real-time operating current value. The real-time operating environment data includes the real-time ambient light intensity value of each external light source, the real-time ambient color temperature value, and the real-time ambient spectral reflectance value of each object.

[0030] The color rendering value is the degree to which the light source generated by the lamp to be controlled can truly restore the color of the object, and the color rendering value can be measured by a colorimeter, and the measurement result is input into the database.

[0031] The color temperature value is the "temperature" of the light source generated by the lamp to be controlled, that is, the color tendency of the light emitted by the light source, and the color temperature value can be measured by a color temperature meter, and the measurement result is input into the database.

[0032] The brightness value is the intensity of the light emitted by the light source generated by the lamp to be controlled, and the brightness value can be measured by a lumen meter, and the measurement result is input into the database.

[0033] The operating current value is the current passing through the lamp to be controlled. When the current increases, more electrons and holes recombine, thereby releasing more energy, resulting in increased light output. Therefore, increasing the current will increase the brightness. At the same time, increasing the current will usually increase the color temperature, becoming colder white; while reducing the current will reduce the color temperature, becoming warmer. A lower current can provide a higher color rendering index, while a higher current will reduce the color rendering index. The operating current value can be obtained through a current sensor.

[0034] The electric field strength value is the strength of the electric field in the external environment where the lamp is located. It can be measured by an electric field strength meter and the measurement results are entered into the database. At the same time, an excessively strong electric field will increase the current through induction or interference, or induce an instantaneous current pulse through the electrostatic effect, resulting in an increase in current.

[0035] The magnetic field strength value is the strength of the magnetic field in the external environment where the lamp is located, which can be obtained through the Hall sensor. At the same time, an excessively strong magnetic field will increase the current through electromagnetic interference, causing the current to increase.

[0036] The real-time ambient light intensity value is the light intensity (luminous flux received per unit area) of each existing external light source in the external environment where the lamp is located (such as external light source (sunlight or other nearby light sources). The light intensity of each existing light source in the external environment can be obtained by the light sensor. When the real-time ambient light intensity value is low, the color of the object will be unclear. At this time, the color rendering value of the lamp can be adjusted upward. If the real-time ambient light intensity value is too large, a glare effect will occur, making the color of the object appear unnatural, and then the color rendering value of the lamp will be lowered. At the same time, if the real-time ambient light intensity value is too large, the brightness value will decrease, and if it is too small, the brightness value will increase.

[0037] The real-time ambient color temperature value is the temperature of the light color emitted by each existing external light source in the external environment where the lamp is located. A low color temperature light source (such as yellow light) appears as warm light, and a higher color temperature (such as white light or blue-white light) appears as cold light. The temperature of the light color emitted by each existing external light source can be obtained through a color temperature sensor. At the same time, if the real-time ambient color temperature value is low (such as yellow light or candlelight), the color temperature of the lamp will be adjusted to a warmer color temperature (that is, the color temperature value decreases); if the ambient color temperature is high (such as white light or blue light), the color temperature of the lamp will be adjusted to a cooler color temperature (that is, the color temperature value increases) to match the environment and enhance comfort; and when the color temperature is high (cold light), the brightness of the lamp can be appropriately adjusted down to avoid excessive light. On the contrary, the brightness perception is weak, and the brightness is appropriately increased to maintain the effectiveness of the lighting.

[0038] The real-time environmental spectral reflectance value is the reflectance of the surface of each object in the external environment where the lamp is located to light. The reflectance of the surface of each object to light can be measured by a spectral reflectance meter, and the measurement results are input into a database. If the real-time environmental spectral reflectance value is small, it will lead to poor color rendering, thereby increasing the color rendering value of the lamp, enhancing the visibility and realism of the color, and vice versa, it helps to enhance the color restoration. At this time, the color rendering value of the lamp is adjusted upward; at the same time, the real-time environmental spectral reflectance value is small, the light will be absorbed, causing the ambient light to appear warmer, so the color temperature perception is warmer, then the color temperature value of the lamp is adjusted upward, otherwise, it is adjusted downward; and the real-time environmental spectral reflectance value is small, the low reflectance surface will absorb a lot of light, resulting in weak brightness perception and a darker overall environment, so the brightness value of the lamp is adjusted upward, otherwise, it is adjusted downward.

[0039] Specifically, if Figure 2 As shown, the specific steps of obtaining the regression coefficient set are as follows: perform difference analysis on the previous color rendering value, previous color temperature value, previous brightness value, and previous operating current value of each previous time period of the lamps to be controlled in the set area, respectively, to obtain the previous color rendering change value, previous color temperature change value, previous brightness change value, and previous current change value of each group of adjacent previous time periods of the lamps to be controlled in the set area; and perform standardization processing (i.e., removing the unit processing) on ​​the previous color rendering change value, previous color temperature change value, previous brightness change value, and previous current change value of each group of adjacent previous time periods of the lamps to be controlled in the set area; divide the previous current change value of each group of adjacent previous time periods of the lamps to be controlled in the set area after the standardization processing with the previous color rendering change value, previous color temperature change value, and previous brightness change value by time period, to obtain several groups of regression data; input each group of regression data into the multivariate regression model for analysis and prediction, to obtain the color temperature regression coefficient, the brightness regression coefficient, and the color rendering regression coefficient, i.e., the regression coefficient set.

[0040] The specific process of comprehensive analysis is as follows: For the multivariate regression model, the least squares method is selected for analysis, that is, the least squares method is to calculate the sum of squares of the minimized errors and use it as the objective function, and the expression of the objective function is: , is the loss function, The first The previous current change value of the group of adjacent previous time periods, is the intercept term of the multiple regression model, The first The previous color temperature change value of the group of adjacent previous time periods, is the color temperature regression coefficient, The first The previous brightness change value of the group of adjacent previous time periods, is the brightness regression coefficient, The first The previous color change value of the group's adjacent previous time period, is the color regression coefficient, is the error term of the multiple regression model, , is the number of adjacent previous time period groups, and each unknown parameter in the multivariate regression model (such as color temperature regression coefficient, brightness regression coefficient, color rendering regression coefficient) is analyzed based on the objective function, that is, the partial derivative of each unknown parameter is calculated, the partial derivative result is set to 0, the corresponding equation is obtained, and the value of each unknown parameter is obtained by solving the corresponding equation.

[0041] The details of the multiple regression model are as follows: ;in, is the current change value, is the intercept term of the multiple regression model, is the previous color temperature change value, is the color temperature regression coefficient, is the previous brightness change value, is the brightness regression coefficient, is the previous color change value, is the color regression coefficient, is the error term of the multiple regression model.

[0042] In this implementation scheme, by performing difference analysis and standardization on the previous time period data of the lamps to be controlled in the set area, and then combining with the multivariate regression model for comprehensive analysis, it is possible to accurately capture the influence of each factor (such as color temperature, brightness) on the change of lamp current, which helps to improve the accuracy of regulation and reduce the deviation caused by changes in the external environment or other uncontrollable factors. The regression coefficient can reflect the weight and relationship of each factor, so as to provide more accurate data support for subsequent regulation decisions, thereby ensuring that the lamps can maintain the expected lighting effect under different environmental conditions. Secondly, by obtaining historical lighting effect operation status data in real time and performing multivariate regression modeling, it does not only rely on fixed parameters, but can be dynamically adjusted according to actual operation data, thereby providing stable and efficient lighting effect control in various application scenarios (such as museums, exhibition halls, etc.). Finally, by solving the regression coefficient and applying the error minimization objective function, the current regulation amount can be optimized, thereby improving the efficiency of power use, and extending the service life of the lamps, reducing maintenance costs, and providing guarantees for energy saving and cost-effectiveness in long-term use.

[0043] Specifically, the specific steps for obtaining the real-time color temperature control amount, real-time brightness control amount, and real-time color rendering control amount of the lamps to be controlled in the set area are as follows: perform weighted average processing on the real-time ambient light intensity value, real-time ambient color temperature value of each external light source of the lamps to be controlled in the set area, and the real-time ambient spectral reflectance value of each object, to obtain the comprehensive real-time ambient light intensity value, comprehensive real-time ambient color temperature value, and comprehensive real-time ambient spectral reflectance value of the lamps to be controlled in the set area; read the real-time color temperature value of the lamps to be controlled in the set area, and obtain the ambient light intensity reference value and ambient reflectance reference value of the lamps to be controlled in the set area; The real-time color temperature value, ambient light intensity reference value, ambient reflectivity reference value, real-time ambient light intensity value, comprehensive real-time ambient color temperature value, and comprehensive real-time ambient spectral reflectivity value of the lamps to be controlled are comprehensively analyzed to obtain the real-time color temperature control index, real-time environment control index, and real-time color rendering control index of the lamps to be controlled in the set area; and the real-time brightness value and real-time color rendering value of the lamps to be controlled in the set area are read, and the real-time color temperature value is combined with the real-time color temperature control index, the real-time environment control index, and the real-time color rendering control index for comprehensive analysis to obtain the real-time color temperature control amount, real-time brightness control amount, and real-time color rendering control amount of the lamps to be controlled in the set area.

[0045] It needs to be explained that The specific acquisition process is as follows: read the real-time ambient color temperature value of each external light source of the lamps to be controlled in the set area, and perform standardization processing, perform sum analysis based on the results after standardization processing to obtain the comprehensive color temperature and value, and perform proportion analysis on the real-time ambient color temperature value of each external light source of the lamps to be controlled in the set area after standardization processing and the comprehensive color temperature and value, and use the proportion analysis result as the corresponding weighting coefficient.

[0046] Furthermore, the calculation logic and calculation formula of the comprehensive real-time ambient color temperature value, the comprehensive real-time ambient spectral reflectance value and the comprehensive real-time ambient light intensity value of the lamps to be controlled in the set area are consistent.

[0047] The ambient light intensity reference value is the standard light intensity value in indoor environments and can be obtained through the lighting database of the International Illumination Commission.

[0048] The ambient reflectance reference value is the standard reflectance value in the indoor environment, which can be obtained through the optical database. It should be noted that the optical database only describes the reflectance of each object, but the objects in the indoor environment are different, and the reflectance of each object is also different, so 0.5 is selected as the ambient reflectance reference value.

[0049] The formula for calculating the real-time color temperature control index and real-time ambient brightness control index of the lamps to be controlled in the set area is as follows: ;in, To set the real-time color temperature control index of the lamps to be controlled in the area, To set the comprehensive real-time ambient color temperature value of the lamps to be controlled in the area, is the real-time color temperature value of the lamps to be controlled in the set area (it should be noted here that the closer the color temperature value of the lamps is to the comprehensive real-time environmental color temperature value, the stronger the ability to restore color, so the real-time color temperature value is selected as the reference value), is the gain coefficient stored in the database, and in this implementation example, the value is 5. is the color temperature correction coefficient stored in the database, It is the comprehensive real-time ambient spectral reflectance value of the lamps to be controlled in the set area.

[0051] , The specific acquisition process is: read the ambient light intensity reference value and the ambient reflectivity reference value of the lamps to be controlled in the set area, perform standardization processing, perform sum analysis based on the results after standardization processing to obtain the brightness control sum value, and perform proportion analysis on the ambient light intensity reference value and the ambient reflectivity reference value of the lamps to be controlled in the set area after standardization processing and the brightness control sum value, and use the proportion analysis results as the corresponding coefficients.

[0052] And the Tanh function is a hyperbolic tangent function, the domain is all real numbers, the range is (-1, 1), and the expression is: ;in, is the hyperbolic tangent function, is a natural constant and in this embodiment takes a value of 2.71.

[0053] The specific steps for calculating the real-time color rendering control index of the lamps to be controlled in the set area are as follows: ;in, To set the real-time color rendering control index of the lamps to be controlled in the area, To set the comprehensive real-time ambient color temperature value of the lamps to be controlled in the area, To set the comprehensive real-time ambient color temperature value of the lamps to be controlled in the area, is the gain coefficient stored in the database, and in this implementation example, the value is 5. Correct the color temperature coefficient for color rendering stored in the database.

To set the ambient reflectance reference value of the lamps to be controlled in the area, Corrected reflectance for color rendering stored in the database, The comprehensive real-time ambient light intensity value of the lamps to be controlled in the set area. It is the reference value of the ambient light intensity of the lamps to be controlled in the set area. is the color correction illumination coefficient stored in the database, .

[0054] It needs to be explained that , , The specific acquisition process is: read the real-time color temperature value, ambient reflectance reference value, and ambient light intensity reference value of the lamps to be controlled in the set area, perform standardization processing, perform sum analysis based on the results after standardization processing, and obtain the color rendering correction value, and perform proportion analysis on the real-time color temperature value, ambient reflectance reference value, and ambient light intensity reference value of the lamps to be controlled in the set area after standardization processing and the color rendering correction value, and use the proportion analysis results as the corresponding coefficients.

[0055] An implementation example of calculating the real-time color rendering control index of the lamps to be controlled in a set area is as follows:

[0056] The following data are available:

[0057] The comprehensive real-time ambient color temperature value of the lamps to be controlled in the set area is: 3840.58K.

[0058] The comprehensive real-time ambient spectral reflectance value of the lamps to be controlled in the set area is: 0.58.

[0059] The comprehensive real-time ambient light intensity value of the lamps to be controlled in the set area is: 329.48 lux.

[0060] The real-time ambient color temperature value of the lamps to be controlled in the set area is: 3500.00K.

[0061] The reference value of the ambient reflectivity of the lamps to be controlled in the set area is: 0.50.

[0062] The reference value of the ambient light intensity of the lamps to be controlled in the set area is: 300.00lux.

[0063] The color rendering correction color temperature coefficient stored in the database is: 0.46.

[0064] The color correction reflectance coefficient stored in the database is: 0.32.

[0065] The color rendering correction illumination coefficient stored in the database is: 0.22.

[0066] Substitute the above data into the real-time color rendering control index formula of the lamps to be controlled in the set area.

[0067] Then the real-time color rendering control index of the lamps to be controlled in the set area = Tanh ((0.46*(1-(3840.58 / 3500.00))*5)+(0.32*((0.58 / 0.50)-1)*5)+(0.22*(1-(329.48 / 300.00)*5)≈-0.07.

[0068] In this implementation, the real-time environmental data of the external light source in the set area is weighted averaged and standardized, and combined with the real-time status data of the lamp for comprehensive analysis, so as to fully consider the impact of the external environment on the lamp, thereby making the lamp more adaptable, and the real-time color temperature, brightness, color rendering and other data under different lighting conditions are optimized through weighted coefficients, standardization and other methods, which can more accurately adjust the working state of the lamp to ensure that it can always achieve the expected lighting effect in a complex environment, and then make the parameters such as the color temperature and brightness of the lamp automatically adjusted in different external environments to better adapt to environmental changes and improve the applicability and comfort of the light. Secondly, through multiple standardization and comprehensive analysis methods, factors such as ambient light intensity, color temperature and reflectivity are incorporated into the control algorithm, thereby effectively improving the performance of the lamp in various environments. The color rendering ability under various lighting environments is calculated, and the real-time color rendering control index is calculated to adjust the color rendering value of the lamp in real time according to the changes in the external environment to ensure that the lamp can provide more accurate color reproduction. In museums, exhibition halls and other environments, it is very important to ensure the true color and details of the exhibits, thereby avoiding color deviation caused by lighting changes, thereby enhancing the consistency of visual effects and the accuracy of display effects. Finally, by combining parameters such as ambient light intensity, reflectivity and color temperature with the Tanh function for regulation, the energy efficiency of the lamp can be optimized. When the ambient light intensity is high, the lamp can automatically reduce the brightness and adjust the color temperature to reduce power consumption; when the light is weak, the lamp will automatically increase the brightness and adjust the color temperature to meet the needs, thereby effectively avoiding energy waste and improving the energy efficiency of the lamp.

[0069] Specifically, the specific steps for obtaining the real-time current control amount of the lamps to be controlled in the set area are as follows: normalize the real-time color temperature control amount, real-time brightness control amount, and real-time color rendering control amount of the lamps to be controlled in the set area (i.e., remove the unit); and comprehensively analyze the real-time color temperature control amount, real-time brightness control amount, and real-time color rendering control amount of the lamps to be controlled in the set area after normalization with the color temperature regression coefficient, brightness regression coefficient, and color rendering regression coefficient to obtain the real-time current control index of the lamps to be controlled in the set area; and read the real-time operating current value of the lamps to be controlled in the set area, and analyze it in combination with the real-time current control index to obtain the real-time current control amount of the lamps to be controlled in the set area; wherein, the formula for calculating the real-time current control index of the lamps to be controlled in the set area is as follows: ;in, To set the real-time current control index of the lamps to be controlled in the area, is the real-time color temperature control value of the lamps to be controlled in the set area after normalization. is the color temperature regression coefficient, is the real-time brightness control value of the lamps to be controlled in the set area after normalization. is the brightness regression coefficient, It is the real-time color control value of the lamps to be controlled in the set area after normalization. is the color regression coefficient, and .

[0070] In this embodiment, by normalizing the real-time color temperature control amount, brightness control amount and color rendering control amount, the unit difference between different parameters is eliminated, so that each control amount has the same calculation basis, so that in the subsequent analysis process, a comprehensive analysis is performed with the color temperature, brightness and color rendering regression coefficients in a unified manner to ensure the accurate calculation of the current control amount, and then the current output of the lamp can be optimized in real time to meet different lighting needs in a more efficient way. Secondly, the normalized control amount can be flexibly adjusted according to the changes in the environment, and by combining it with the regression coefficient, the current control amount can be dynamically adjusted according to the actual environment. In particular, when the ambient light intensity, color temperature, brightness, etc. are constantly changing, the real-time optimization of the lamp current can be achieved, so that it can provide the expected lighting effect in different environments. Secondly, on the basis of real-time acquisition of the lamp operating current and control amount, the current control amount is calculated immediately and real-time feedback is provided to ensure that the lamp adjusts quickly and accurately in the changing environment. The calculation and application of the real-time control amount can ensure that the lamp works in a state that meets the expectations, thereby avoiding energy efficiency loss or unsatisfactory lighting effect due to response lag.

[0071] Specifically, the specific steps for regulating the real-time operating current value based on the real-time current control amount of the lamps to be controlled in the set area are as follows: compare and analyze the real-time current control amount of the lamps to be controlled in the set area with the preset upper limit of the control threshold interval (i.e., the maximum value of the control interval) and the lower limit of the control threshold interval (i.e., the minimum value of the control interval); if the real-time current control amount of the lamps to be controlled in the set area is lower than the preset lower limit of the control threshold interval, then the real-time current control amount of the lamps to be controlled in the set area is adjusted upward (i.e., until the real-time operating current value of the lamps to be controlled in the set area is increased to a current value that meets the real-time current control amount, and the operating current is increased by adjusting the driving power supply); if the real-time current control amount of the lamps to be controlled in the set area is higher than the preset upper limit of the control threshold interval, then the real-time current control amount of the lamps to be controlled in the set area is adjusted downward (i.e., until the real-time operating current value of the lamps to be controlled in the set area is reduced to a current value that meets the real-time current control amount, and the operating current is reduced by adjusting the driving power supply).

[0072] In this embodiment, by comparing the real-time current control amount with the preset threshold, the current output is accurately adjusted. When the real-time current control amount is lower than the preset threshold, the current is automatically reduced to avoid ineffective consumption of energy; conversely, when the control amount is higher than the threshold, the current is automatically increased to meet the lighting needs, thereby ensuring that the lamp always maintains the expected lighting effect under different environments, while greatly improving the energy utilization efficiency. Secondly, it can respond to changes in the external environment (such as changes in light intensity, color temperature, etc.) in real time, dynamically adjust the current, and automatically adjust the operating current of the lamp according to the real-time current control amount. It can flexibly adapt to different lighting needs, and by accurately controlling the operating current of the lamp, it is avoided that excessive or too small current affects the working state of the lamp, thereby effectively reducing excessive wear of electrical components, thereby avoiding heat and damage caused by excessive current, or insufficient brightness of the lamp due to too low current, thereby extending the service life of the lamp. Finally, based on the comparison of the real-time current control amount with the threshold, it can intelligently determine whether the current needs to be adjusted, and provide personalized and flexible lighting solutions.

[0074] In summary, this application has at least the following effects:

[0075] By using a multivariate regression model to predict and analyze previous lighting operation status data, the current control amount required for the lamp can be accurately calculated in real time, thereby optimizing the brightness, color temperature and color rendering effect of the lamp, and avoiding over-control, thereby achieving energy saving, and then effectively reducing the waste of electricity, making a positive contribution to environmental protection, especially in special environments such as museums, and being able to effectively maintain appropriate lighting requirements.

[0076] By acquiring environmental data such as ambient light intensity and ambient color temperature in real time and making dynamic adjustments based on regression models, lamps can automatically optimize color temperature, brightness and color rendering effects according to real-time environmental changes, thereby ensuring that lamps can always provide expected light quality, thereby adapting to changes in different time periods and environmental conditions, and subsequently improving the light environment quality of the overall space.

[0077] By accurately judging and adjusting the real-time current value and the current control amount, the damage to the lamp caused by current fluctuations can be effectively avoided. For example, when the current exceeds the preset threshold, timely adjustments can be made to prevent excessive or insufficient current from affecting the normal operation of the lamp, thereby reducing the loss of the lamp in long-term use, reducing the failure rate, and then extending the service life of the lamp and reducing maintenance costs.

[0078] Through the coordinated work of multiple functional modules such as data acquisition module, prediction analysis module, data analysis module, and comprehensive analysis module, accurate monitoring and control of the operating status of the lamp can be achieved. By acquiring and analyzing environmental data and the operating status of the lamp in real time, the current control amount of the lamp can be dynamically adjusted to adapt to different environmental changes. For example, under different lighting conditions and temperature changes, the lamp can automatically adjust the color temperature, brightness and color rendering effect to ensure that the expected effect is achieved, thereby improving the intelligence of the lamp and enhancing the lamp's ability to adapt to environmental changes, thereby improving the user's visual comfort and experience.
