[0035] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1: Please refer to Figure 1 - Figure 2 , the present application provides an adaptive adjustment system for a lighting device based on laser illumination to excite fluorescence, including;

[0037] A wavelength data collection terminal, which presets multiple usage durations and is used to obtain multiple laser wavelengths corresponding to each region of the fluorescent material of the laser lighting device at different usage durations. The specific method is as follows:

[0038] The fluorescent material region of the laser lighting device is partitioned, and at the same time, excitation measurement points are set in each region. Multiple excitation wavelengths corresponding to the excitation measurement points in each region of the fluorescent material at different usage durations are collected through a high-precision spectrometer;

[0039] The specific method for partitioning the fluorescent material region of the laser lighting device is as follows: The fluorescent material region of the laser lighting device is evenly divided into multiple regions i, and the center point position of each region is used as the excitation measurement point D i in different regions, where i represents different regions, i = 1, 2,..., a1, where a1 represents the number of regions, and a1 is a positive integer and a2 is greater than 1;

[0040] Obtain multiple excitation wavelengths Jf i j corresponding to the excitation measurement points in each region of the fluorescent material at different usage durations, where f represents different usage durations, f = 1, 2, ……, a2, where a2 represents the number of usage durations, a2 is a positive integer and a2 > 1, and j represents different excitation wavelengths corresponding to the excitation measurement points in each region at different usage durations, j = 1, 2, ……, a3, where a3 is the number of excitation wavelengths corresponding to the excitation measurement points in each region at different usage durations, a3 is a positive integer and a3 > 1;

[0041] Use high-precision optical equipment such as spectrometers to detect the excitation wavelengths at the excitation measurement points in each region to ensure wavelength accuracy and stability. The above belongs to existing and mature technologies;

[0042] Through the use of high-precision spectrometers, the high-precision and high-stability collection of excitation wavelengths is ensured. This is very important for subsequent data analysis and calculation. Uniformly dividing the fluorescent material region into multiple regions and setting excitation measurement points in each region helps to comprehensively obtain the wavelength data of each region and avoid system performance deviations caused by insufficient local data.

[0043] The wavelength data analysis terminal, based on the partition analysis of different excitation wavelengths corresponding to the excitation measurement points in each region of the fluorescent material at different usage durations, obtains the calibration wavelengths corresponding to each region of the fluorescent material at different usage durations. The specific analysis method is as follows:

[0044] Perform mean processing on the different excitation wavelengths corresponding to the excitation measurement points in each region of the fluorescent material at different usage durations to obtain the calibration wavelengths Bf i corresponding to each region at different usage durations;

[0045] The specific method for obtaining the calibration wavelengths Bf i corresponding to each region at different usage durations is as follows:

[0046] Randomly select a region from each region as the calibration region, and at the same time select a usage duration from multiple preset durations as the calibration duration. Obtain the mean of different excitation wavelengths of the calibration region of the fluorescent material at the calibration duration and use it as the calibration wavelength corresponding to the calibration region of the fluorescent material at the calibration duration. Use the same analysis method to analyze the different excitation wavelengths corresponding to each region at different usage durations, and then obtain the calibration wavelengths corresponding to each region at different usage durations.

[0047] The calibrated wavelength represents the average excitation wavelength of each region under a specific usage duration, which is used for subsequent calculation of the propulsion coefficient. By averaging the excitation wavelength data of each region, the calibrated wavelength is obtained. This process helps reduce noise and adaptability to long-term use: the calculation of the calibrated wavelength can reflect the degradation or performance changes of the material under different usage durations, enabling the system to adapt to the performance decline during long-term use.

[0048] The propulsion coefficient acquisition end determines the horizontal region groups and vertical region groups of the fluorescent material according to the excitation measurement points, and analyzes based on the calibrated wavelengths corresponding to each region in each horizontal region group and vertical region group of the fluorescent material under different usage durations, so as to obtain the wavelength horizontal propulsion coefficient and wavelength vertical propulsion coefficient corresponding to the fluorescent material under different usage durations respectively. The specific method is as follows:

[0049] The specific method for determining the horizontal region groups and vertical region groups of the fluorescent material according to the excitation measurement points is as follows:

[0050] In the order from top to bottom, according to the excitation measurement points, determine the horizontal region groups and vertical region groups of the fluorescent material. The regions corresponding to the excitation measurement points on the same horizontal line are calibrated as the same horizontal region group. In the order from left to right, the regions corresponding to the excitation measurement points on the same vertical line are calibrated as the same vertical region group, so as to obtain each horizontal region group LAe and vertical region group LBc of the fluorescent material. The horizontal horizontal line is perpendicular to the vertical horizontal line, where e represents different horizontal region groups of the fluorescent material, and c represents different vertical region groups of the fluorescent material;

[0051] The specific method for obtaining the wavelength horizontal propulsion coefficient corresponding to each horizontal region group of the fluorescent material under different usage durations is as follows:

[0052] S1: Select a usage duration from a preset multiple durations as the analysis duration;

[0053] S2: Randomly select one from multiple horizontal region groups as the analysis region group;

[0054] Normalize the calibrated wavelength Fb of each region in the analysis region group under the analysis duration. The specific method for normalizing the calibrated wavelength Fb is: obtain the maximum value Fmax in the calibrated wavelength Fb, obtain the ratio Bb between Fb and Fmax respectively, and use it as the comparison value Bb corresponding to each region in the analysis region group under the analysis duration, where b represents different regions in the analysis region group;

[0055] First, obtain the difference between the maximum value Fmax and the minimum value Fmin in the comparison value Bb, and use the ratio between it and the maximum value Fmax as the calibration value Zb. Then, obtain the ratio between the comparison values Bb of every two adjacent regions within each region in the analysis region group under the analysis duration. Delete the ratios greater than the calibration value Zb, and record the number c of the deleted ratios. When c is greater than the preset value Y1, use the mean value of all the ratios as the variation coefficient HA11 of the analysis region group under the analysis duration. When c is less than or equal to the preset value Y1, use the mean value of the maximum and minimum values among all the ratios as the variation coefficient HA11 of the analysis region group under the analysis duration. The specific value of the preset value Y1 is determined by relevant personnel according to actual needs;

[0056] S3: Repeat step S2, and the corresponding variation coefficients HA1 e of different horizontal region groups under the analysis duration can be obtained. Use the mean value of the maximum and minimum values in HA1 e as the horizontal propulsion coefficient TA1 under the analysis duration;

[0057] S4: Repeat steps S1 - S3, and the corresponding horizontal propulsion coefficients TAf at different durations can be obtained;

[0058] Adopt the same analysis method as obtaining the corresponding horizontal propulsion coefficients of different horizontal region groups at different durations to analyze the calibration wavelengths corresponding to each region in different vertical region groups of the fluorescent material at different usage durations, and then obtain the corresponding vertical propulsion coefficients TBf at different durations;

[0059] According to the calibration wavelength, calculate the corresponding horizontal propulsion coefficient and vertical propulsion coefficient of the fluorescent material at different durations to quantify the influence of wavelength change on the excitation efficiency.

[0060] By calculating the propulsion coefficients of the horizontal and vertical regions of the fluorescent material, the influence of wavelength change in different regions on the excitation efficiency can be quantified, providing an accurate basis for subsequent laser power adjustment, thus ensuring the consistency of the light source. Through the processing of the horizontal and vertical region groups, the system can handle the wavelength changes of the light source in different directions and adapt to different lighting requirements and application scenarios.

[0061] The excitation influence coefficient determination end analyzes the corresponding horizontal propulsion coefficient and vertical propulsion coefficient of the fluorescent material at different durations, and then obtains the excitation influence coefficient corresponding to the fluorescent material. The specific method is as follows:

[0062] Taking different durations Tf as the horizontal axis and the corresponding horizontal and vertical propulsion coefficients of the fluorescent material at different durations as the vertical axis, a horizontal curve graph and a vertical curve graph of the fluorescent material are obtained. The specific method for obtaining the horizontal curve graph of the fluorescent material is as follows: Taking different durations Tf as the abscissa values and the corresponding horizontal propulsion coefficients of the fluorescent material at different durations as the ordinate values, a horizontal curve graph of the fluorescent material is obtained. Then, the horizontal data point coordinates RAf(Tf, TAf) corresponding to the fluorescent material at different usage durations are obtained. The line connecting every two horizontal data points is used as a horizontal transformation line. The slope Kr of each horizontal transformation line is obtained according to the horizontal data point coordinates of the two horizontal data points that make up each horizontal transformation line. Here, r represents different horizontal transformation lines, r = 1, 2, ……, a4, where a4 is the number of horizontal transformation lines, a4 is a positive integer and a4 is greater than or equal to 1. The number of positive and negative values +G and -G of the slope Kr is obtained. When +G is greater than a4 / 2, the mean value of the slope Kr is taken as the horizontal influence coefficient M1 corresponding to the fluorescent material. When -G is greater than a4 / 2, the product of the mean value of the slope Kr and negative one is taken as the horizontal influence coefficient M1 corresponding to the fluorescent material. Otherwise, the mean value of the maximum and minimum values of the slope Kr is taken as the horizontal influence coefficient M1 corresponding to the fluorescent material;

[0063] The specific method for obtaining the vertical curve graph of the fluorescent material is as follows: Taking different durations Tf as the abscissa values and the corresponding vertical propulsion coefficients of the fluorescent material at different durations as the ordinate values, a vertical curve graph of the fluorescent material is obtained. The vertical curve graph is analyzed using the same analysis method as the horizontal curve graph, and then the vertical influence coefficient M2 corresponding to the fluorescent material is obtained;

[0064] The horizontal influence coefficient M1 and the vertical influence coefficient M2 corresponding to the fluorescent material are analyzed to obtain the excitation influence coefficient JF corresponding to the fluorescent material. The specific method is as follows:

[0065] The excitation influence coefficient JF corresponding to the fluorescent material is obtained through JF = M1×β1 + M2×β2, where β1 and β2 are both preset proportionality coefficients. The specific values of β1 and β2 are determined by relevant personnel according to actual needs, satisfying 1 = β1 + β2, 1 > β1 > 1 / 2 > β2 > 0;

[0066] By combining the horizontal and vertical propulsion coefficients, a comprehensive excitation influence coefficient is provided. By analyzing these influence coefficients, the impacts of different factors on the light source efficiency can be more accurately identified and quantified, further improving the control accuracy of the system. According to the calculation of the excitation influence coefficient, the laser power can be intelligently adjusted, the light source performance can be optimized, and the consumption of ineffective energy can be reduced.

[0067] Embodiment 2: As the second embodiment of the present invention, when the present application is specifically implemented, compared with Embodiment 1, the technical solution of this embodiment is only different from that of Embodiment 1 in that this embodiment further includes an execution end;

[0068] The execution end obtains the adjusted laser power of the laser illumination device according to the real-time usage duration of the laser illumination device, the expected laser power, and the excitation influence coefficient corresponding to the fluorescent material, and adjusts the laser illumination device according to the adjusted laser power. The specific method is as follows:

[0069] Through P 调 =P 预 +TS×JF, calculate the adjusted laser power P 调 of the laser illumination device, where P 预 is the expected laser power, which can be provided by the factory value, design value or system calibration value of the device. TS is the real-time usage duration of the laser illumination device. The specific time to obtain TS is before each start-up of the laser illumination device. During the use of the laser illumination device, the real-time usage duration is no longer obtained. Obtaining the usage duration before each start-up can perform precise adjustment each time the device is used, rather than continuously measuring during operation. This not only improves the flexibility of system response but also reduces the requirements for hardware performance.

[0070] Calculate the adjusted laser power according to the real-time usage duration, expected laser power and excitation influence coefficient, and adjust the power of the laser illumination device according to the calculation result to ensure the stability and efficiency of the light source.

[0071] Automatically adjusting the laser power according to the real-time usage duration and excitation influence coefficient can monitor the performance degradation of the fluorescent material in real time and automatically adjust the laser power to adapt to the change of the fluorescent material, ensure the stability of the lighting effect, optimize energy use, and reduce device loss, so that the system can maintain stable and efficient operation under different usage conditions. By adjusting the laser power, it is possible to prevent uneven brightness or performance degradation of the light source caused by degradation or environmental factors. By adjusting the laser power in real time, energy waste can be reduced and overall efficiency can be improved, which is particularly important in large-scale applications.

[0072] Embodiment 3: As the third embodiment of the present invention, when the present application is specifically implemented, compared with Embodiment 1 and Embodiment 2, the technical solution of this embodiment is to combine the solutions of the above Embodiment 1 and Embodiment 2 for implementation.

[0073] The above formulas are all calculated by taking the numerical values without dimensions. The formula is obtained by software simulation of a large amount of collected data to get a formula closest to the real situation. The preset parameters and threshold selection in the formula are set by those skilled in the art according to the actual situation.

[0074] As described above, it is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed by this application can easily think of changes or substitutions, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims described.
