[0019] The dimming method, device and lamp provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0020] Figure 1 A method for dimming a lamp provided by an embodiment of the present invention is shown. The method can be performed by an electronic device, which may include a terminal. The method can be performed by software or hardware installed in the electronic device, and the method includes the following steps:

[0021] Step 102: Obtain a first parameter index of the lamp according to optical measurement data of the lamp.

[0022] The first parameter index includes a first brightness and lumen adjustment range of the lamp and a first color temperature adjustment range corresponding to the first brightness and lumen adjustment range.

[0023] Specifically, the hardware, structure, and optical components of the lamp can be inspected using optical experimental measurement equipment to obtain the required optical measurement data of the lamp. The optical measurement data may specifically include the initial brightness lumen adjustment range of the lamp, the minimum dimming control signal that can be output, the color coordinates of cold light and warm light, etc. The optical measurement data can be obtained according to actual needs and is not specifically limited here.

[0024] Based on the optical measurement data of the lamp, the optical measurement data is processed accordingly to obtain a first parameter indicator. The first parameter indicator includes a first brightness lumen adjustment range of the lamp and a first color temperature adjustment range corresponding to the first brightness lumen adjustment range. The first brightness lumen adjustment range and the first color temperature adjustment range are parameter indicators that meet the requirements and are obtained based on the optical measurement data. Within the first brightness lumen adjustment range and the first color temperature adjustment range, it can be ensured that the color temperature and brightness values ​​do not interfere with each other during adjustment and are accurately output.

[0025] Step 104: Obtain target performance parameters of the lamp.

[0026] Specifically, the target performance data may be target performance data input by the user, wherein the target performance parameters include a target brightness value and a target color temperature value, that is, the target brightness value may be the brightness value required by the user input by the user, and the target color temperature value may be the color temperature value required by the user input by the user.

[0027] Step 106: Output a target dimming control signal according to the target performance parameter and the first parameter indicator.

[0028] Specifically, the target dimming control signal is used to control the output brightness and output color temperature of the lamp. According to the target brightness value and target color temperature value in the target performance parameters, the brightness lumens corresponding to the target brightness value and the color temperature value corresponding to the target color temperature value are determined within the first parameter index. According to the brightness lumens corresponding to the target brightness value and the color temperature value corresponding to the target color temperature value, the corresponding dimming control information is determined and output so that the brightness and color temperature output of the lamp meet the user's needs.

[0029] A method for dimming a lamp provided by an embodiment of the present invention obtains a first parameter index of the lamp based on optical measurement data of the lamp, wherein the first parameter index includes a first brightness lumen adjustment range of the lamp and a first color temperature adjustment range corresponding to the first brightness lumen adjustment range; obtains target performance parameters of the lamp, wherein the target performance parameters include a target brightness value and a target color temperature value; outputs a target dimming control signal based on the target performance parameters and the first parameter index, wherein the target dimming control signal is used to control the output brightness and output color temperature of the lamp, and can determine and output a control control signal that meets user needs based on the target brightness value and target color temperature value input by the user and the first parameter index, thereby achieving accurate output of color temperature and brightness of the lamp to meet user needs.

[0030] In one implementation, obtaining the first parameter index of the lamp based on the optical measurement data of the lamp includes:

[0031] Obtaining optical measurement data of a light-mixing component constituting the lamp using optical experimental measurement equipment, wherein the light-mixing component includes a cold light module and a warm light module; obtaining a second parameter index of the lamp using a preset dimming algorithm based on the optical measurement data, wherein the second parameter index includes a second brightness lumen adjustment range of the lamp and a second color temperature adjustment range corresponding to the second brightness lumen adjustment range; and obtaining the first parameter index by optimizing the second parameter index by adjusting the light-mixing component based on pre-set index requirement information.

[0032] Specifically, optical experimental measurement equipment is used to test a light-mixing component that constitutes the lamp to obtain optical measurement data of the light-mixing component, where the light-mixing component includes a cold light module and a warm light module. Based on the obtained optical measurement data, a preset dimming algorithm can be used to obtain a second parameter indicator of the lamp, where the second parameter indicator includes a second brightness lumen adjustment range of the lamp and a second color temperature adjustment range corresponding to the second brightness lumen adjustment range. The light-mixing component can be adjusted according to pre-set indicator requirement information to optimize the second parameter indicator to obtain the first parameter indicator.

[0033] In this way, intervention can be made in the early stages of lamp design, the light-mixing components that make up the lamp can be tested, and optical measurement data of the light-mixing components can be obtained. According to pre-set indicator requirement information, the light-mixing components can be adjusted and the second parameter indicator can be optimized to obtain the first parameter indicator, which can ensure that the color temperature and brightness values ​​do not interfere with each other during adjustment and are accurately output.

[0034] In one implementation, outputting a target dimming control signal according to the target performance parameter and the first parameter indicator includes:

[0035] Determining a first brightness lumen value corresponding to the target brightness within the first brightness lumen adjustment range; determining a third color temperature adjustment range corresponding to the first brightness lumen value based on the first brightness lumen value; directly outputting the target dimming control signal based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range, or determining whether the target color temperature value is within the third color temperature adjustment range and outputting the target dimming control signal based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range.

[0036] Specifically, Figure 2 A schematic diagram of a lamp module provided by an embodiment of the present invention is shown. Figure 2 The module diagram shown is used to explain in detail the dimming method of the lamp in this application:

[0037] In the early stages of lamp design, the relevant light mixing components of the lamp can be tested using optical experimental measurement equipment to obtain the required optical measurement data, where the light mixing components include cold light modules and warm light modules;

[0038] In the early stages of lamp design, the third brightness lumen adjustment range corresponding to the cold light module and the first corresponding relationship can be determined by adjusting the output of the first dimming control signal corresponding to the cold light module based on optical measurement data. The first corresponding relationship is the correspondence between the first dimming control signal output by the cold light module, the brightness lumen value corresponding to the cold light module, and the cold light color coordinates corresponding to the cold light module.

[0039] Determining, based on the optical measurement data, a fourth brightness lumen adjustment range corresponding to the warm light module and a second corresponding relationship by adjusting the output of the second dimming control signal corresponding to the warm light module, wherein the second corresponding relationship is a correspondence between the second dimming control signal output by the warm light module and the brightness lumen value corresponding to the warm module and the warm light color coordinates corresponding to the warm light module;

[0040] For example, by obtaining N groups of data as shown in the following table, the first correspondence and the second correspondence are calculated:

[0041]

[0042]

[0043] Among them, if the relationship between the dimming control signal output of the lamp itself and the brightness lumen value and color coordinates is not smooth, that is, a multi-order function may be required to describe the relationship between the dimming control signal output and the brightness lumen value and color coordinates, then increasing the number N will help to more accurately describe the relationship between the dimming control signal output and the brightness lumen value and color coordinates, thereby reducing calculation errors.

[0044] Because the relationship between the dimming control signal and the brightness, lumen, or color coordinates may be uneven at low brightness levels, but relatively smooth at high brightness levels, additional test points can be added during low dimming control signal intervals and fewer during high dimming control signal intervals. The lamp parameter evaluation module can use a preset dimming algorithm based on the optical measurement data to determine a second parameter for the lamp. The second parameter includes a second brightness and lumen adjustment range for the lamp and a second color temperature adjustment range corresponding to the second brightness and lumen adjustment range. Specifically, the second brightness and lumen adjustment range can be determined based on a third brightness and lumen adjustment range and a fourth brightness and lumen adjustment range.

[0045] For any brightness lumen value within the second brightness lumen adjustment range, keep any brightness lumen value unchanged, adjust the output of the first dimming control signal of the cold light module and the second dimming control signal of the warm light module, when the output of the first dimming control signal is minimum and the output of the second dimming control signal is maximum, determine the color coordinates of the cold light and the color coordinates of the warm light at this time respectively through the first corresponding relationship and the second corresponding relationship, and then calculate the maximum color temperature corresponding to any brightness lumen value through the dimming algorithm; adjust the output of the first dimming control signal of the cold light module and the second dimming control signal of the warm light module, when the output of the first dimming control signal is minimum and the output of the second dimming control signal is maximum When the output is maximum and the second dimming control signal is maximum, the color coordinates of the cold light and the color coordinates of the warm light are respectively determined by the first corresponding relationship and the second corresponding relationship. Then, the minimum color temperature corresponding to any brightness lumen value is calculated by the preset dimming algorithm. According to the maximum color temperature and the minimum color temperature, the color temperature range corresponding to the brightness lumen value is determined. The color temperature range corresponding to all brightness lumen values ​​within the second brightness lumen range is calculated to obtain the second color temperature adjustment range corresponding to the second brightness lumen adjustment range. According to needs, reference information of theoretical deviation of the second brightness lumen adjustment range and the second color temperature adjustment range can also be obtained.

[0046] According to the preset index requirement information, the light mixing component is adjusted to optimize the second parameter index to obtain the first parameter index, for example Figure 3 The schematic diagram of the relationship between brightness lumens and color temperature is shown. In the lamp parameter index evaluation module, based on the acquired optical measurement data, a second brightness lumen adjustment range and a second color temperature adjustment range of the lamp shown in 301 can be obtained. The second brightness lumen adjustment range and the second color temperature adjustment range can be further optimized in the lamp parameter index optimization module according to product requirements to obtain the first brightness lumen adjustment range and the first color temperature adjustment range shown in 302. The actual parameter information of the light mixing component of the lamp corresponding to the first parameter index can also be generated through the lamp parameter generation module.

[0047] In this way, the second parameter index of the lamp can be obtained according to the optical measurement data of the lamp, which allows designers to adjust the light mixing components of the lamp according to the needs and the second parameter index to obtain the first parameter index, so as to meet the requirements of the lamp in the initial stage of lamp design and realize the optimization of the lamp, ensuring that the color temperature and brightness values ​​do not interfere with each other during adjustment and are accurately output.

[0048] In one implementation, the preset dimming algorithm includes a first formula and a second formula, wherein:

[0049] The first formula is:

[0050] Bo=f1(L1,L2);

[0051] The second formula is: CCTo=f2(L1,cx1,cy1,L2,cx2,cy2);

[0052] Wherein, in the first formula, Bo represents the brightness value of the lamp, f1 function represents the first standard light mixing formula, L1 represents the brightness lumen value of the cold light module, and L2 represents the brightness lumen value of the warm light module;

[0053] In the second formula, CCTo represents the color temperature value closest to the target color temperature value, the f2 function represents the second standard light mixing formula, L1 represents the brightness lumen value of the cold light module, (cx1, cy1) represents the color coordinates of the cold light corresponding to the cold light module, L2 represents the brightness lumen value of the warm light module, and (cx2, cy2) represents the color coordinates of the warm light corresponding to the warm light module.

[0054] In one implementation, outputting a target dimming control signal according to the target performance parameter and the first parameter indicator includes:

[0055] Determining a first brightness lumen value corresponding to the target brightness within the first brightness lumen adjustment range; determining a third color temperature adjustment range corresponding to the first brightness lumen value based on the first brightness lumen value; directly outputting the target dimming control signal based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range, or determining whether the target color temperature value is within the third color temperature adjustment range and outputting the target dimming control signal based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range.

[0056] Specifically, according to the target brightness, the first brightness lumen corresponding to the target brightness is determined, the first brightness lumen is determined within the first brightness lumen adjustment range, and the third color temperature adjustment range corresponding to the first brightness lumen is determined within the first color adjustment range. The target dimming control signal is output directly according to the first brightness lumen value, the target color temperature value and the third color temperature adjustment range, or it is determined whether the target color temperature value is within the third color temperature adjustment range, and the target dimming control signal is output according to the first brightness lumen value, the target color temperature value and the third color temperature adjustment range.

[0057] In this way, by determining the first brightness lumen value corresponding to the target brightness within the first brightness lumen adjustment range; determining the third color temperature adjustment range corresponding to the first brightness lumen value based on the first brightness lumen value; directly outputting the target dimming control signal based on the first brightness lumen value, the target color temperature value and the third color temperature adjustment range, or judging whether the target color temperature value is within the third color temperature adjustment range, and outputting the target dimming control signal based on the first brightness lumen value, the target color temperature value and the third color temperature adjustment range, the brightness and color temperature required by the user can be accurately determined and output based on the target parameters, the problem of being unable to accurately output the brightness and color temperature of the lamp can be solved, and the design of the lamp is more humane and can meet the needs of users.

[0058] In one implementation, directly outputting the target dimming control signal according to the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range, or outputting the target dimming control signal according to the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range when the judgment result is that the target color temperature value is within the third color temperature adjustment range, includes:

[0059] The first brightness lumen value is maintained unchanged, and the third dimming control signal output by the cold light module and the fourth dimming control signal output by the warm light module are adjusted; each time the output of the third dimming control signal and the output of the fourth dimming control signal are adjusted, the color temperature value corresponding to the first brightness lumen value is calculated by a preset dimming algorithm until the calculated color temperature value is the first color temperature value closest to the target color temperature value within the third color temperature adjustment range; the target dimming control signal is output according to the output of the third dimming control signal and the output of the fourth dimming control signal corresponding to the first color temperature value.

[0060] Specifically, the target dimming control signal can be directly output according to the first brightness lumen value, the target color temperature value and the third color temperature adjustment range, or when the judgment result is that the target color temperature value is within the third color temperature adjustment range, the target dimming control signal can be output according to the first brightness lumen value, the target color temperature value and the third color temperature adjustment range.

[0061] Specifically, the first brightness lumen value is kept unchanged, the third dimming control signal output by the cold light module and the fourth dimming control signal output by the warm light module are adjusted multiple times, the adjustment of the third dimming control signal and the adjustment of the fourth control signal do not exceed the preset adjustment threshold, the first brightness lumen value is kept unchanged, and the output of the third dimming control signal and the output of the fourth dimming control signal are adjusted from the minimum of the third dimming control signal, the maximum of the fourth dimming control signal, or the minimum of the third dimming control signal and the fourth dimming control signal, each time the third dimming control signal and the fourth dimming control signal are adjusted by a preset unit, each time the third dimming control signal output by the cold light module is adjusted, each time the cold light module is adjusted, the third dimming control signal output by the cold light module is adjusted, and each time the cold light module is adjusted, the third dimming control signal output by the cold light module is adjusted. The third dimming control signal output by the optical module and the fourth dimming control signal output by the warm light module determine the adjusted cold light brightness lumens and cold light color coordinates according to the first corresponding relationship. Each time the fourth dimming control signal output by the warm light module is adjusted, the adjusted warm light brightness lumens and warm light color coordinates are determined according to the second corresponding relationship. Through the preset dimming algorithm, all color temperature values ​​corresponding to the first brightness lumen value are calculated, and the first color temperature value closest to the target color temperature value is found among all color temperature values ​​corresponding to the first brightness lumen value. At this time, the target dimming control signal is output according to the output of the third dimming control signal and the output of the fourth dimming control signal corresponding to the first color temperature value.

[0062] In this way, by keeping the first brightness lumen value unchanged, adjusting the third dimming control signal output by the cold light module and the fourth dimming control signal output by the warm light module, each time the output of the third dimming control signal and the output of the fourth dimming control signal are adjusted, the color temperature value corresponding to the first brightness lumen value is calculated through the first correspondence, the second correspondence and the preset dimming algorithm, until the calculated color temperature value is the first color temperature value closest to the target color temperature value within the third color temperature adjustment range; according to the output of the third dimming control signal and the output of the fourth dimming control signal corresponding to the first color temperature value, the target dimming control signal is output, the first color temperature closest to the target color temperature value can be found, and according to the output of the third dimming control signal and the output of the fourth dimming control signal corresponding to the first color temperature value, the target dimming control signal is output, thereby achieving accurate output of the brightness and color temperature of the lamp according to user needs, thereby meeting user needs.

[0063] In one implementation, when the determination result is that the target color temperature value is not within the third color temperature adjustment range, outputting the target dimming control signal according to the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range includes:

[0064] A second color temperature value closest to the target color temperature value within the first color temperature adjustment range is determined by a preset dimming algorithm; the fifth dimming control signal output by the cold light module and the sixth dimming control signal output by the warm light module are adjusted while keeping the second color temperature value unchanged; each time the output of the fifth dimming control signal and the sixth dimming control signal are adjusted, a brightness lumen value corresponding to the second color temperature value is calculated by a preset dimming algorithm until the calculated brightness lumen value is a second brightness lumen value closest to the first brightness lumen value within the first brightness lumen adjustment range; and the target dimming control signal is output based on the output of the fifth dimming control signal and the output of the sixth dimming control signal corresponding to the second brightness lumen value.

[0065] Specifically, if the target color temperature value is not within the third color temperature adjustment range, a second color temperature value closest to the target color temperature value is determined within the first color temperature adjustment range through a preset dimming algorithm, the second color temperature value is kept unchanged, and the fifth dimming control signal output by the cold light module and the sixth dimming control signal output by the warm light module are adjusted, wherein the adjustment of the fifth dimming control signal and the adjustment of the sixth dimming control signal do not exceed the preset adjustment threshold, and the adjustment is started from the minimum value corresponding to the fifth dimming control signal and the minimum value of the sixth dimming control signal, and the output of the fifth dimming control signal and the output of the sixth dimming control signal are adjusted by a preset unit each time, and each time the output of the fifth dimming control signal is adjusted, the adjustment is obtained through the first corresponding relationship. The fifth dimming control signal and the brightness lumens corresponding to the fifth dimming control signal are adjusted each time the output of the sixth dimming control signal is adjusted, and the brightness lumens corresponding to the adjusted sixth dimming control signal and the sixth dimming control signal are obtained through the second corresponding relationship. Each time the output of the fifth dimming control signal and the sixth dimming control signal is adjusted, all brightness values ​​corresponding to the second color temperature value are calculated according to the brightness lumens corresponding to the fifth dimming control signal and the brightness lumens corresponding to the sixth dimming control signal through a preset dimming algorithm, and an output brightness value closest to the target brightness value is determined among all brightness values ​​corresponding to the second color temperature value; the target dimming control signal is output according to the output of the fifth dimming control signal and the output of the sixth dimming control signal corresponding to the output brightness value.

[0066] In this way, the output of the fifth dimming control signal and the sixth dimming control signal can be adjusted through the target brightness value and the target color temperature value input by the user, and the brightness value corresponding to the second color temperature value is calculated through the first correspondence, the second correspondence and the preset dimming algorithm until the calculated brightness value is the output brightness value closest to the target brightness value; according to the output of the fifth dimming control signal and the output of the sixth dimming control signal corresponding to the output brightness value, the target dimming control signal is output, thereby realizing accurate output of the brightness and color temperature of the lamp according to the user's needs, thereby meeting the user's needs.

[0067] It should be noted that the dimming method for a lamp provided in the embodiments of the present application can be executed by a dimming device for the lamp, or a control module in the dimming device for executing the dimming method for the lamp. In the embodiments of the present application, the dimming device for the lamp provided in the embodiments of the present application is used as an example to illustrate the dimming method for the lamp.

[0068] Figure 4 FIG is a schematic diagram of the structure of a dimming device for a lamp according to an embodiment of the present invention. Figure 4 As shown, the dimming device 400 for a lamp includes: a determination module 410 , an acquisition module 420 and an output module 430 .

[0069] A determination module 410 is used to obtain a first parameter index of the lamp based on the optical measurement data of the lamp, wherein the first parameter index includes a first brightness lumen adjustment range of the lamp and a first color temperature adjustment range corresponding to the first brightness lumen adjustment range; an acquisition module 420 is used to obtain target performance parameters of the lamp, wherein the target performance parameters include a target brightness value and a target color temperature value; an output module 430 is used to output a target dimming control signal based on the target performance parameters and the first parameter index, wherein the target dimming control signal is used to control the output brightness and output color temperature of the lamp.

[0073] In one implementation, the target dimming control signal is output directly based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range. Or, when the judgment result is that the target color temperature value is within the third color temperature adjustment range, the output module 430 is configured to adjust the third dimming control signal output by the cold light module and the fourth dimming control signal output by the warm light module based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range, while maintaining the first brightness lumen value unchanged. Each time the output of the third dimming control signal and the output of the fourth dimming control signal are adjusted, the color temperature value corresponding to the first brightness lumen value is calculated using the first correspondence, the second correspondence, and a preset dimming algorithm until the calculated color temperature value is the first color temperature value closest to the target color temperature value within the third color temperature adjustment range. The target dimming control signal is output based on the output of the third dimming control signal and the output of the fourth dimming control signal corresponding to the first color temperature value.

[0074] In one implementation, when the judgment result is that the target color temperature value is not within the third color temperature adjustment range, the output module 430 is configured to determine, based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range, a second color temperature value within the first color temperature adjustment range that is closest to the target color temperature value using a preset dimming algorithm;

[0084] The dimming device of the lamp provided in the embodiment of the present application can achieve Figures 1 to 3 To avoid repetition, the various processes implemented in the method embodiment will not be described again here.

[0085] Alternatively, as Figure 5 As shown, an embodiment of the present application further provides an electronic device 500, including a processor 501 and a memory 502, wherein the memory 502 stores a program or instruction that can be run on the processor 501, and when the program or instruction is executed by the processor 501, it is implemented as follows: according to the optical measurement data of the lamp, a first parameter index of the lamp is obtained, wherein the first parameter index includes a first brightness lumen adjustment range of the lamp and a first color temperature adjustment range corresponding to the first brightness lumen adjustment range; the target performance parameters of the lamp are obtained, wherein the target performance parameters include a target brightness value and a target color temperature value; according to the target performance parameters and the first parameter index, a target dimming control signal is output, wherein the target dimming control signal is used to control the output brightness and output color temperature of the lamp.

[0086] In one implementation, optical measurement data of a light-mixing component constituting the lamp is obtained using optical experimental measurement equipment, wherein the light-mixing component includes a cold light module and a warm light module. Based on the optical measurement data, a second parameter index of the lamp is obtained using a preset dimming algorithm, wherein the second parameter index includes a second brightness lumen adjustment range of the lamp and a second color temperature adjustment range corresponding to the second brightness lumen adjustment range. Based on pre-set index requirement information, the second parameter index is optimized by adjusting the light-mixing component to obtain the first parameter index.

[0087] In one implementation, based on the optical measurement data, a third brightness lumen adjustment range and a first correspondence corresponding to the cold light module are determined, wherein the first correspondence is a correspondence between a first dimming control signal output by the cold light module and the brightness lumen value corresponding to the cold light module, and a cold light color coordinate corresponding to the cold light module; based on the optical measurement data, a fourth brightness lumen adjustment range and a second correspondence are determined corresponding to the warm light module, wherein the second correspondence is a correspondence between a second dimming control signal output by the warm light module and the brightness lumen value corresponding to the warm module, and a warm light color coordinate corresponding to the warm light module; based on the third brightness lumen adjustment range and the fourth brightness lumen adjustment range, the second brightness lumen adjustment range is determined; for any brightness lumen value within the second brightness lumen adjustment range, the any brightness lumen value is kept unchanged, and the color temperature adjustment range corresponding to the any brightness lumen value is obtained based on the first correspondence, the second correspondence, and a preset dimming algorithm.

[0088] In one implementation, a first brightness lumen value corresponding to the target brightness is determined within the first brightness lumen adjustment range. A third color temperature adjustment range corresponding to the first brightness lumen value is determined based on the first brightness lumen value.

Alternatively, it is determined whether the target color temperature value is within the third color temperature adjustment range, and the target dimming control signal is output based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range.

[0089] In one implementation, the target dimming control signal is output directly based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range. Or, when the judgment result is that the target color temperature value is within the third color temperature adjustment range, the first brightness lumen value is maintained unchanged, and the third dimming control signal output by the cold light module and the fourth dimming control signal output by the warm light module are adjusted based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range. Each time the output of the third dimming control signal and the output of the fourth dimming control signal are adjusted, the color temperature value corresponding to the first brightness lumen value is calculated using the first correspondence, the second correspondence, and a preset dimming algorithm until the calculated color temperature value is the first color temperature value closest to the target color temperature value within the third color temperature adjustment range. The target dimming control signal is output based on the output of the third dimming control signal and the output of the fourth dimming control signal corresponding to the first color temperature value.

[0090] In one implementation, when the judgment result is that the target color temperature value is not within the third color temperature adjustment range, a second color temperature value closest to the target color temperature value within the first color temperature adjustment range is determined by a preset dimming algorithm based on the first brightness lumen value, the target color temperature value, and the third color temperature adjustment range;

[0091] Keeping the second color temperature value unchanged, adjust the fifth dimming control signal output by the cold light module and the sixth dimming control signal output by the warm light module; each time the output of the fifth dimming control signal and the sixth dimming control signal are adjusted, calculate the brightness value corresponding to the second color temperature value through the first correspondence, the second correspondence, and the preset dimming algorithm until the calculated brightness value is an output brightness value closest to the target brightness value; output the target dimming control signal according to the output of the fifth dimming control signal and the output of the sixth dimming control signal corresponding to the output brightness value.

[0092] In one implementation, the preset dimming algorithm includes a first formula and a second formula, wherein:

[0093] The first formula is:

[0094] Bo=f1(L1,L2);

[0095] The second formula is: CCTo=f2(L1,cx1,cy1,L2,cx2,cy2);

[0096] Wherein, in the first formula, Bo represents the brightness value of the lamp, f1 function represents the first standard light mixing formula, L1 represents the brightness lumen value of the cold light module, and L2 represents the brightness lumen value of the warm light module;

[0097] In the second formula, CCTo represents the color temperature value closest to the target color temperature value, the f2 function represents the second standard light mixing formula, L1 represents the brightness lumen value of the cold light module, (cx1, cy1) represents the color coordinates of the cold light corresponding to the cold light module, L2 represents the brightness lumen value of the warm light module, and (cx2, cy2) represents the color coordinates of the warm light corresponding to the warm light module.
