Description

Technical Field

[0001] The present invention relates to the field of lighting control technology, and in particular to a lighting equipment light control method and device based on a multi-chip combination. Background Art

[0002] With the development of LED film and television lighting technology, the requirements for the overall power of LED equipment and the quality of light emitted are becoming higher and higher. The common light control solution usually uses the DX12410 constant current chip to control the current output, and changes the DX12410 current output size through PWM modulation to change the brightness of the light source.

[0003] However, the light control scheme using a single DX12410 constant current chip to control lighting equipment has defects, specifically: when PWM is small, DX12410 does not enter the constant current area, resulting in a large difference in output current, which leads to different light source start-up, reduces the accuracy of light combination, and different lighting equipment performs differently at low brightness; at this time, you can consider introducing the MBI5030 chip to replace the low brightness part of DX12410. The MBI5030 chip can control low current output more accurately. However, the difficulty of controlling the two chips together lies in how to integrate the lighting data of the two chips. It can be seen that it is particularly important to provide a technical solution to improve the integration accuracy of lighting data when multiple light control chips are used in combination to improve the control accuracy of each light control chip.

Figure 1 As shown, the lighting control method of the lighting device based on the multi-chip combination may include the following operations:

[0095] 101. Collect a first lighting data set of a lighting device under the control of a first light control chip and a second lighting data set of a lighting device under the control of a second light control chip.

[0096] In the embodiment of the present invention, optionally, the lighting device may include one or more output light sources. The current output by the first light control chip is greater than the current output by the second light control chip. The lighting data of each lighting point in the first lighting data set and the second lighting data set are collected when the lighting device outputs the corresponding brightness.

[0097] In the embodiment of the present invention, the first light control chip can be a DX12410 chip, or other chips that can play the same role of controlling the large current part of the lighting device. The second light control chip can be an MBI5030 chip, or other chips that can play the same role of controlling the small current part of the lighting device.

[0098] For example, when controlling the brightness of the light source output by lighting equipment (such as LED movie lights), the current of the DX12410 chip and the MBI5030 chip are individually controlled to output from small to large, and at the same time, a lighting instrument is used to collect basic data from the minimum brightness value to the maximum brightness value of each channel of the DX12410 chip and the MBI5030 chip to obtain a lighting data set for each chip.

[0099] 102. Determine a first virtual connection point from all second lighting points in the second lighting data set according to all lighting data in the first lighting data set and all lighting data in the second lighting data set.

[0100] In an embodiment of the present invention, optionally, the lighting data may include a PWM control quantity (a control quantity of pulse width modulation control, and the brightness of the lighting equipment can be finely controlled by setting the PWM duty cycle) and / or an illuminance value. The lighting data may also include color coordinate parameters and any other arbitrary parameters that can be collected by the lighting instrument, which is not limited in the embodiment of the present invention.

[0101] 103. Integrate the first lighting data set and the second lighting data set according to the lighting data of the first virtual connection point to obtain a target lighting data set corresponding to the lighting equipment.

[0102] In the embodiment of the present invention, the first lighting data set, the second lighting data set and the target lighting data set can all be presented in the form of a table. In this way, when it is necessary to control the illumination value / PWM control amount of the lighting device, it is only necessary to find the corresponding value in the corresponding table.

[0103] In the embodiment of the present invention, optionally, the lighting data of all first lighting points whose PWM control amount is greater than the PWM control amount of the first virtual connection point can be directly selected from the lighting data of all first lighting points in the first lighting data set, and the lighting data of all second lighting points whose PWM control amount is less than or equal to the PWM control amount of the first virtual connection point can be selected from the lighting data of all second lighting points in the second lighting data set, based on the lighting data of the first virtual connection point. All the selected lighting data can be integrated to obtain the target lighting data set corresponding to the lighting equipment.

[0104] Further optionally, based on the lighting data of the first virtual connection point, a second virtual connection point can be determined from all the first lighting points in the first lighting data set; and based on the lighting data of the first virtual connection point, the lighting data of all second lighting points in the second lighting data set whose PWM control amount is less than or equal to the PWM control amount of the first virtual connection point can be selected; and based on the lighting data of the second virtual connection point, the lighting data of all first lighting points in the first lighting data set whose PWM control amount is greater than the PWM control amount of the first virtual connection point can be selected; and all the selected lighting data are then integrated to obtain the target lighting data set corresponding to the lighting equipment.

[0105] 104. According to the target lighting data set, control the first light control chip and the second light control chip to perform brightness control operations on the lighting device.

[0106] It can be seen that implementation Figure 1 The described lighting control method for a lighting device based on a multi-chip combination can collect a first lighting data set of the lighting device under the control of a first light control chip and a second lighting data set under the control of a second light control chip; according to all the lighting data sets, a first virtual connection point is determined from all the second lighting points of the second lighting data set, which can improve the accuracy and efficiency of determining the first virtual connection point used as a basis for integrating the lighting data; and according to the lighting data of the first virtual connection point, the first lighting data set and the second lighting data set are integrated to obtain a target lighting data set; then, according to the target lighting data set, the first light control chip and the second light control chip are controlled to perform a brightness control operation on the lighting device, which can improve the integration accuracy and efficiency of the lighting data collected when different chips are controlled separately when multiple light control chips are used in combination, and can improve the control accuracy and efficiency of each light control chip based on the accurately integrated lighting data, thereby facilitating the improvement of the output accuracy of the brightness of the lighting device, and facilitating the reduction of the difference in chip output current by using a combination of multiple chips under different lighting data (such as PWM control amount), thereby facilitating the improvement of the consistency of each light source in the lighting device, and facilitating the improvement of the light combination accuracy of the lighting device.

[0107] In an optional embodiment, the step 102 of determining the first virtual connection point from all second lighting points in the second lighting data set according to all lighting data of the first lighting data set and all lighting data of the second lighting data set may include:

[0109] Establishing a second lighting curve for the second light control chip according to the PWM control quantities and illumination values ​​of all second lighting points in the second lighting data set;

[0110] According to the first daylighting curve and the second daylighting curve, one or more second daylighting points satisfying a preset slope similarity condition are determined from all second daylighting points in the second daylighting data set as candidate daylighting points;

[0111] When the number of candidate lighting points is 1, determine the candidate lighting point as the first virtual connection point;

[0112] When the number of candidate daylighting points is greater than 1, the candidate daylighting point closest to the preset output boundary of the second light control chip is selected from all the candidate daylighting points according to the PWM control amounts of all the candidate daylighting points as the first virtual connection point.

[0113] In the embodiment of the present invention, the preset output boundary may be a preset maximum value of the PWM control amount that can be output by the second light control chip.

[0114] Exemplarily, for each lighting data set in the first lighting data set and the second lighting data set, a lighting curve of the lighting data set is established with the PWM control amount of all lighting points in the lighting data set as the x-axis and the illumination value of all lighting points in the lighting data set as the y-axis.

[0115] It can be seen that this optional embodiment can establish a first lighting curve for the first light control chip based on the PWM control quantities and illuminance values ​​of all first light points in the first light data set; and establish a second lighting curve for the second light control chip based on the PWM control quantities and illuminance values ​​of all second light points in the second light data set, thereby improving the accuracy and efficiency of establishing the lighting curve for each light control chip; then, based on the first light curve and the second light curve, one or more second light points that meet the preset slope similarity condition are determined from all the second light points in the second light data set as alternative light points; and when the number of alternative light points is 1, the alternative light point is determined as the first virtual connection point, providing The efficiency and speed of determining the first virtual connection point are improved; when the number of alternative light points is greater than 1, the alternative light point closest to the preset output boundary of the second light control chip is screened out from all the alternative light points according to the PWM control amount of all the alternative light points as the first virtual connection point, thereby improving the accuracy and reliability of determining the first virtual connection point, and by selecting a point as close as possible to the output boundary of the second light control chip as the virtual connection point, it can ensure that when multiple chips are used in combination in the future, the lighting data of the second light control chip that is less affected by temperature is used as much as possible, which is beneficial to improving the control accuracy of the low brightness output of the lighting device, and is beneficial to improving the consistency of the output brightness of each light source in the lighting device.

[0116] In this optional embodiment, as an optional implementation, according to the first daylighting curve and the second daylighting curve, one or more second daylighting points satisfying the preset slope similarity condition are determined from all second daylighting points in the second daylighting data set as candidate daylighting points, which may include:

[0117] For each first daylighting point in the first daylighting curve, the slope of the first daylighting point is calculated according to the PWM control amount of the first daylighting point and the illumination value of the first daylighting point;

[0118] For each second daylighting point in the second daylighting curve, the slope of the second daylighting point is calculated according to the PWM control amount of the second daylighting point and the illumination value of the second daylighting point;

[0119] Calculate the difference between the slope of the second daylighting point and the slope of each first daylighting point to obtain the slope difference corresponding to the second daylighting point;

[0120] One or more second light-collecting points with the smallest corresponding slope difference are selected from all the second light-collecting points as candidate light-collecting points.

[0121] It can be seen that this optional implementation method can calculate the slope of each first light point in the first light curve based on the PWM control amount and the illuminance value of the first light point; and calculate the slope of each second light point in the second light curve based on the PWM control amount and the illuminance value of the second light point, thereby improving the calculation accuracy of the slope of the light point of each chip; and calculate the difference between the slope of the second light point and the slope of each first light point to obtain the slope difference corresponding to the second light point; and then select one or more second light points with the smallest corresponding slope difference from all the second light points as alternative light points, which can improve the screening accuracy and reliability of the alternative light points used as the first virtual connection points, thereby facilitating improving the accuracy of determining the subsequent first virtual connection points.

[0122] Embodiment 2

[0123] See also Figure 2 , Figure 2 1 is a flow chart of a method for controlling light of a lighting device based on a multi-chip combination disclosed in an embodiment of the present invention. Figure 2 The described method for controlling light of a lighting device based on a multi-chip combination can be applied to a lighting device based on a multi-chip combination, wherein the device may include a light control device or a light control server, wherein the light control server may include a cloud server or a local server, which is not limited in the embodiments of the present invention. Figure 2 As shown, the lighting control method of the lighting device based on the multi-chip combination may include the following operations:

[0124] 201. Collect a first lighting data set of a lighting device under the control of a first light control chip and a second lighting data set of a lighting device under the control of a second light control chip.

[0125] 202. Determine a first virtual connection point from all second lighting points in the second lighting data set according to all lighting data in the first lighting data set and all lighting data in the second lighting data set.

[0126] 203. Determine a second virtual connection point corresponding to the first lighting data set according to the illumination value of the first virtual connection point and the first lighting data set.

[0127] 204. According to the PWM control amount of the first lighting data set, determine from the first lighting data set all first lighting data whose PWM control amount is greater than or equal to the PWM control amount of the second virtual connection point as the first lighting data group that needs to be merged.

[0128] In the embodiment of the present invention, the first light data group is used as an output basis of the first light control chip when the first light control chip is used in combination with the second light control chip.

[0129] For example, assuming that the PWM control amount of the second virtual connection point is 1100, and the maximum PWM control amount in the first lighting data set is 10000, the lighting data of all first lighting points with PWM control amounts of 1100-10000 are determined as the first lighting data group that needs to be merged.

[0130] 205. According to the PWM control amount of the second lighting data set, determine from the second lighting data set all second lighting data whose PWM control amount is less than or equal to the PWM control amount of the first virtual connection point as the second lighting data group that needs to be merged.

[0131] In the embodiment of the present invention, the second lighting data group is used as an output basis of the second light control chip when the first light control chip and the second light control chip are used in combination.

[0132] For example, assuming that the PWM control value of the first virtual connection point is 9000 and the minimum PWM control value in the second lighting data set is 0, the lighting data of all second lighting points with PWM control values ​​of 0-9000 are determined as the second lighting data set that needs to be merged.

[0133] 206. Integrate the first lighting data set and the second lighting data set to obtain a target lighting data set corresponding to the lighting equipment.

[0134] 207. Control the first light control chip and the second light control chip to perform brightness control operations on the lighting device according to the target lighting data set.

[0135] In the embodiment of the present invention, for other descriptions of step 201, step 202 and step 207, please refer to the detailed description of step 101, step 102 and step 104 in the first embodiment, and the embodiment of the present invention will not be repeated.

[0136] It can be seen that implementation Figure 2 The described lighting control method for a lighting device based on a multi-chip combination can collect a first lighting data set of the lighting device under the control of a first light control chip and a second lighting data set under the control of a second light control chip; according to all the lighting data sets, a first virtual connection point is determined from all the second lighting points of the second lighting data set, which can improve the accuracy and efficiency of determining the first virtual connection point used as a basis for integrating the lighting data; and according to the lighting data of the first virtual connection point, the first lighting data set and the second lighting data set are integrated to obtain a target lighting data set; then, according to the target lighting data set, the first light control chip and the second light control chip are controlled to perform a brightness control operation on the lighting device, which can improve the integration accuracy and efficiency of the lighting data collected when different chips are controlled separately when multiple light control chips are used in combination, and can improve the control accuracy and efficiency of each light control chip based on the accurately integrated lighting data, thereby facilitating the improvement of the output accuracy of the brightness of the lighting device, and facilitating the reduction of the difference in chip output current by using a combination of multiple chips under different lighting data (such as PWM control amount), thereby facilitating the improvement of the consistency of each light source in the lighting device, and facilitating the improvement of the light combination accuracy of the lighting device. In addition, it is also possible to determine the second virtual connection point corresponding to the first lighting data set based on the illumination value of the first virtual connection point and the first lighting data set; and based on the PWM control amount of the first lighting data set, determine from the first lighting data set all the first lighting data whose PWM control amount is greater than or equal to the PWM control amount of the second virtual connection point as the first lighting data group that needs to be merged; and, based on the PWM control amount of the second lighting data set, determine from the second lighting data set all the second lighting data whose PWM control amount is less than or equal to the PWM control amount of the first virtual connection point as the second lighting data group that needs to be merged, which can combine multiple virtual connection points to improve the accuracy and efficiency of determining the lighting data group that needs to be merged in each chip; and then integrate the first lighting data group and the second lighting data group to obtain the target lighting data set corresponding to the lighting equipment, which can improve the accuracy and efficiency of the integrated target lighting data set.

[0137] In an optional embodiment, the integration of the first lighting data set and the second lighting data set in step 206 to obtain a target lighting data set corresponding to the lighting device may include:

[0138] For each second lighting point in the second lighting data group, determining the PWM control amount of the second lighting point as the order value of the second lighting point;

[0139] For each first lighting point in the first lighting data group, the PWM control amount of the first lighting point and the PWM control amount of the first virtual combo point in the second lighting data group are combined to obtain the order value of the first lighting point;

[0140] The first lighting data group and the second lighting data group are sorted according to the order values ​​of all lighting points in the first lighting data group and the second lighting data group to obtain a target lighting data set corresponding to the lighting device.

[0141] For example, assuming that the PWM control amount in the second lighting data group is 0-9000, and the PWM control amount of the first virtual connection point is 9000, and the PWM control amount in the first lighting data group is 1100-10000, then the order value of the first lighting point with a PWM control amount of 1100 can be 1100+9000=10100.

[0142] It can be seen that this optional implementation can directly determine the PWM control amount of each second light point in the second light data group as the order value of the second light point, and fuse the PWM control amount of each first light point in the first light data group and the PWM control amount of the first virtual combo point in the second light data group to obtain the order value of the first light point, which can improve the accuracy and reliability of determining the order value used as the basis for sorting each light point. Subsequently, the first light data group and the second light data group are sorted according to the order values ​​of all light points in the first light data group and the second light data group to obtain the target light data set corresponding to the lighting equipment, which can improve the sorting accuracy and reliability of the first light data group and the second light data group, and can improve the integration accuracy and reliability of the target light data set.

[0143] In another optional embodiment, determining the second virtual connection point corresponding to the first lighting data set according to the illumination value of the first virtual connection point and the first lighting data set in the above step 203 may include:

[0144] According to the illumination value of the first virtual connection point, determining whether there is a first lighting point whose illumination value is equal to that of the first virtual connection point among the illumination values ​​in the lighting data of all first lighting points included in the first lighting data set;

[0145] When it is determined that there is a first lighting point having an illumination value equal to that of the first virtual connection point, determining the first lighting point having an illumination value equal to that of the first virtual connection point as a second virtual connection point corresponding to the first lighting data set;

[0146] When it is determined that there is no first daylighting point with the same illumination value as the first virtual connection point, a first daylighting point that satisfies the adjacent illumination value condition corresponding to the first virtual connection point is selected from all the first daylighting points according to the illumination values ​​of all the first daylighting points and the illumination value of the first virtual connection point;

[0147] The second virtual connection point corresponding to the first lighting data set is obtained by fitting according to the lighting data of all first lighting points that meet the adjacent illumination value condition and the illumination value of the first virtual connection point.

[0148] In the embodiment of the present invention, the adjacent illumination value condition includes a condition that the illumination values ​​of all first lighting points sorted according to the illumination values ​​are adjacent to the illumination value of the first virtual connection point.

[0149] For example, assume that there is a first virtual connection point A (9000, 500), indicating that the PWM control amount of point A = 9000, and the illuminance value E of point A = 500 Lux, and assume that in the table corresponding to the first lighting data set, only the lighting points with illuminance values ​​above and below 500 Lux are found, namely (1000, 490) and (1100, 510), indicating that when the first light control chip (such as DX12410) controls the PWM control amount to be output to 1000, the corresponding illuminance value is 490 Lux, and when the first light control chip controls the PWM control amount to be output to 1100, the corresponding illuminance value is 510 Lux. At this time, the two lighting points are connected into a straight line, and a 500 lux point is fitted linearly, and the point P (1050, 500) is fitted as the second virtual connection point corresponding to the first lighting data set.

[0150] It can be seen that this optional embodiment can determine whether there is a first daylighting point with an illumination value equal to the illumination value of the first virtual connection point in the lighting data of all the first daylighting points included in the first daylighting data set according to the illumination value of the first virtual connection point; and when it is determined that there is a first daylighting point with an illumination value equal to the first virtual connection point, the first daylighting point with an illumination value equal to the first virtual connection point is determined as the second virtual connection point corresponding to the first daylighting data set, thereby improving the speed and efficiency of determining the second virtual connection point; and when it is determined that there is no first daylighting point with an illumination value equal to the first virtual connection point, the first daylighting point that meets the adjacent illumination value condition corresponding to the first virtual connection point is screened out from all the first daylighting points according to the illumination values ​​of all the first daylighting points and the illumination values ​​of the first virtual connection points, thereby improving the accuracy and efficiency of screening the first daylighting points used as the fitting basis for the second virtual connection point; then, the second virtual connection point corresponding to the first daylighting data set is fitted according to the lighting data of all the first daylighting points that meet the adjacent illumination value condition and the illumination value of the first virtual connection point, thereby improving the fitting accuracy and reliability of the second virtual connection point.

[0151] In yet another optional embodiment, the step 207 of controlling the first light control chip and the second light control chip to perform a brightness control operation on the lighting device according to the target lighting data set may include:

[0152] Obtain the illumination value to be output that is currently required by the lighting device; determine the PWM control amount to be output that matches the illumination value to be output from the target lighting data set according to the target lighting data set;

[0153] Comparing the illuminance value to be output with the illuminance value of the first virtual connection point to obtain an illuminance value comparison result;

[0154] When the illuminance value comparison result is used to indicate that the illuminance value to be output is less than the illuminance value of the first virtual connection point, the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output;

[0155] When the illuminance value comparison result is used to indicate that the illuminance value to be output is greater than the illuminance value of the first virtual connection point, the second light control chip is turned off, and the first light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output;

[0156] When the illuminance value comparison result is used to indicate that the illuminance value to be output is equal to the illuminance value of the first virtual connection point, the first light control chip or the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output.

[0157] For example, assuming that there is a first virtual connection point A of (9000, 500) and a fitted second virtual connection point P of (1050, 500), and the illuminance value to be output is equal to 500Lux, the second light control chip can be controlled to output according to point A, that is, the second light control chip can be controlled to output an illuminance value of 500Lux and a PWM control amount of 9000; the first light control chip can also be controlled to output according to point P, that is, the first light control chip can be controlled to output an illuminance value of 500Lux and a PWM control amount of 1050.

[0158] In the embodiment of the present invention, specifically, according to the target lighting data set, determining the PWM control amount to be output that matches the illumination value to be output from the target lighting data set may include:

[0159] According to the target lighting data set, searching whether there is a target illumination value equal to the illumination value to be output in the target lighting data of all target lighting points in the target lighting data set;

[0160] When it is found that the illuminance value of each target lighting data is not equal to the illuminance value to be output, the adjacent lighting points whose illuminance values ​​are adjacent to the illuminance value to be output are selected from all the target lighting points; and the PWM control amount to be output that matches the illuminance value to be output is fitted according to the PWM control amount of all the adjacent lighting points;

[0161] When a target illuminance value equal to the illuminance value to be output is found, the PWM control amount in the lighting data where the target illuminance value is located is determined as the PWM control amount to be output that matches the illuminance value to be output; or

[0162] When a target illuminance value equal to the illuminance value to be output is found, the order value of the lighting point to which the target illuminance value belongs is detected;

[0163] When it is detected that the order value of the light-collecting point is less than or equal to the order value of the first virtual connection point, the order value of the light-collecting point is determined as the PWM control amount to be output that matches the illumination value to be output;

[0164] When it is detected that the order value of the corresponding lighting point is greater than the order value of the first virtual connection point, the order value of the first virtual connection point is separated from the order value of the corresponding lighting point to obtain the PWM control amount to be output that matches the illumination value to be output.

[0165] For example, assuming that the target illumination value is 500Lux, and there is a first virtual connection point A (9000, 500) and a second virtual connection point P (1050, 500), and the order value of the lighting point to which the target illumination value is detected can be 9000 or 10050. Taking 10050 as an example, the order value of the first virtual connection point can be separated therefrom, such as: 10050-9000=1050, as the PWM control quantity to be output.

[0166] It can be seen that this optional embodiment can obtain the illuminance value to be output currently required by the lighting device; according to the target lighting data set, the PWM control amount to be output that matches the illuminance value to be output is determined from the target lighting data set, thereby improving the matching accuracy and screening accuracy of the illuminance value to be output and the PWM control amount to be output, and comparing the illuminance value to be output with the illuminance value of the first virtual connection point. When the illuminance value comparison result is used to indicate that the illuminance value to be output is less than the illuminance value of the first virtual connection point, the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output. By selecting a second light control chip with a small current for control when the illuminance value to be output is small, the output accuracy and refinement of the current can be improved, thereby enabling refined control of the output brightness of the lighting device; when the illuminance value comparison result is used to indicate that the illuminance value to be output is less than the illuminance value of the first virtual connection point, the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output. By selecting a second light control chip with a small current for control when the illuminance value to be output is small, the output accuracy and refinement of the current can be improved, thereby enabling refined control of the output brightness of the lighting device; When the output illuminance value is greater than the illuminance value of the first virtual connection point, the second light control chip is turned off, and the first light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output. By selecting the first light control chip with a large current for control when the illuminance value to be output is large, the output accuracy and stability of the current can be improved, thereby enabling accurate control of the output brightness of the lighting device. When the illuminance value comparison result is used to indicate that the illuminance value to be output is equal to the illuminance value of the first virtual connection point, the first light control chip or the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output. Flexible selection of the light control chip for control when the illuminance value to be output is moderate can improve the flexibility and diversity of the selection of light control chips used to control the brightness of the lighting device.

[0197] It can be seen that this optional implementation can also directly determine the PWM control amount of each second light point in the second light data group as the order value of the second light point, and fuse the PWM control amount of each first light point in the first light data group and the PWM control amount of the first virtual combo point in the second light data group to obtain the order value of the first light point, which can improve the accuracy and reliability of determining the order value used as the basis for sorting each light point. Subsequently, the first light data group and the second light data group are sorted according to the order values ​​of all light points in the first light data group and the second light data group to obtain the target light data set corresponding to the lighting equipment, which can improve the sorting accuracy and reliability of the first light data group and the second light data group, and can improve the integration accuracy and reliability of the target light data set.

[0198] In this optional embodiment, as another optional implementation, the manner in which the integration module 303 determines the second virtual connection point corresponding to the first lighting data set according to the illumination value of the first virtual connection point and the first lighting data set may specifically include:

[0199] According to the illumination value of the first virtual connection point, determining whether there is a first lighting point whose illumination value is equal to that of the first virtual connection point among the illumination values ​​in the lighting data of all first lighting points included in the first lighting data set;

[0200] When it is determined that there is a first lighting point having an illumination value equal to that of the first virtual connection point, determining the first lighting point having an illumination value equal to that of the first virtual connection point as a second virtual connection point corresponding to the first lighting data set;

[0201] When it is determined that there is no first daylighting point with the same illumination value as the first virtual connection point, a first daylighting point that satisfies the adjacent illumination value condition corresponding to the first virtual connection point is selected from all the first daylighting points according to the illumination values ​​of all the first daylighting points and the illumination value of the first virtual connection point;

[0202] The second virtual connection point corresponding to the first lighting data set is obtained by fitting according to the lighting data of all first lighting points that meet the adjacent illumination value condition and the illumination value of the first virtual connection point.

[0203] It can be seen that this optional implementation can determine whether there is a first light point with an illumination value equal to the illumination value of the first virtual connection point in the lighting data of all the first light points included in the first light data set according to the illumination value of the first virtual connection point; and when it is determined that there is a first light point with an illumination value equal to the illumination value of the first virtual connection point, the first light point with an illumination value equal to the illumination value of the first virtual connection point is determined as the second virtual connection point corresponding to the first light data set, thereby improving the speed and efficiency of determining the second virtual connection point; and when it is determined that there is no first light point with an illumination value equal to the illumination value of the first virtual connection point, the first light point that meets the adjacent illumination value condition corresponding to the first virtual connection point is screened out from all the first light points according to the illumination values ​​of all the first light points and the illumination values ​​of the first virtual connection points, thereby improving the accuracy and efficiency of screening the first light points used as the fitting basis for the second virtual connection point; then, the second virtual connection point corresponding to the first light data set is fitted according to the lighting data of all the first light points that meet the adjacent illumination value condition and the illumination value of the first virtual connection point, thereby improving the fitting accuracy and reliability of the second virtual connection point.

[0204] In another optional embodiment, the control module 304 controls the first light control chip and the second light control chip to perform the brightness control operation on the lighting device according to the target lighting data set, which may specifically include:

[0205] Obtain the illumination value to be output that is currently required by the lighting device; determine the PWM control amount to be output that matches the illumination value to be output from the target lighting data set according to the target lighting data set;

[0206] Comparing the illuminance value to be output with the illuminance value of the first virtual connection point to obtain an illuminance value comparison result;

[0207] When the illuminance value comparison result is used to indicate that the illuminance value to be output is less than the illuminance value of the first virtual connection point, the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output;

[0208] When the illuminance value comparison result is used to indicate that the illuminance value to be output is greater than the illuminance value of the first virtual connection point, the second light control chip is turned off, and the first light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output;

[0209] When the illuminance value comparison result is used to indicate that the illuminance value to be output is equal to the illuminance value of the first virtual connection point, the first light control chip or the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output.

[0210] It can be seen that this optional embodiment can obtain the illuminance value to be output currently required by the lighting device; according to the target lighting data set, the PWM control amount to be output that matches the illuminance value to be output is determined from the target lighting data set, thereby improving the matching accuracy and screening accuracy of the illuminance value to be output and the PWM control amount to be output, and comparing the illuminance value to be output with the illuminance value of the first virtual connection point. When the illuminance value comparison result is used to indicate that the illuminance value to be output is less than the illuminance value of the first virtual connection point, the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output. By selecting a second light control chip with a small current for control when the illuminance value to be output is small, the output accuracy and refinement of the current can be improved, thereby enabling refined control of the output brightness of the lighting device; when the illuminance value comparison result is used to indicate that the illuminance value to be output is less than the illuminance value of the first virtual connection point, the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output. By selecting a second light control chip with a small current for control when the illuminance value to be output is small, the output accuracy and refinement of the current can be improved, thereby enabling refined control of the output brightness of the lighting device; When the output illuminance value is greater than the illuminance value of the first virtual connection point, the second light control chip is turned off, and the first light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output. By selecting the first light control chip with a large current for control when the illuminance value to be output is large, the output accuracy and stability of the current can be improved, thereby enabling accurate control of the output brightness of the lighting device. When the illuminance value comparison result is used to indicate that the illuminance value to be output is equal to the illuminance value of the first virtual connection point, the first light control chip or the second light control chip is controlled to output the illuminance value to be output and the PWM control amount to be output, so that the lighting device outputs a brightness that matches the illuminance value to be output. Flexible selection of the light control chip for control when the illuminance value to be output is moderate can improve the flexibility and diversity of the selection of light control chips used to control the brightness of the lighting device.
