Description

Technical Field

[0001] The present application relates to the field of optical lighting technology, and in particular to a method, device, electronic device and storage medium for determining current of mixed light. Background Art

[0002] With the development of light emitting diode (LED) technology, the current (Red, Green, Blue) RGB monochromatic LED technology can achieve a spectrum with a larger half-wave width. The mixed light can obtain light color parameters such as color rendering index, color temperature and luminous flux to meet the spectrum required for use in different scenarios.

[0003] Taking the medical cold light source using RGB synthesized mixed light in the medical scene as an example, since the change of current affects the change of the spectral energy distribution curve, the change of the spectral energy distribution curve will affect the change of optical parameters, such as luminous flux, color temperature, color rendering index, etc., so the optical parameters are closely related to the light source current. Therefore, in order to obtain mixed light whose optical parameters meet the use requirements, in addition to selecting suitable monochromatic light sources, it is also necessary to accurately determine the working current of each monochromatic light source. However, in the prior art, the current of each monochromatic light source is usually adjusted by manual debugging to achieve the purpose of adjusting the radiant flux of the light source. For example, when adjusting the color temperature, increasing the radiant flux of red light can reduce the color temperature of the mixed light, and increasing the radiant flux of blue light can increase the color temperature of the mixed light. According to this rule, a mixed light with the required color temperature can be obtained, and then check whether other light color parameters meet the specified requirements. If not, readjust the current of each monochromatic light source until all light color parameters are met. This manual current adjustment method has a slow adjustment speed, wastes a lot of manpower and time in the adjustment process, and cannot guarantee the optimal color parameters of the mixed light synthesized by the currents of the current monochromatic light sources, and therefore cannot guarantee the effect of the current mixed light.

[0004] Therefore, how to quickly determine the current of each monochromatic light source of the mixed light to ensure a better effect of the obtained mixed light is a technical problem that needs to be solved urgently. Summary of the invention

[0062] In the description of the embodiments of the present application, unless otherwise specified, the term "multiple" refers to two or more, and other quantifiers are similar and should be understood. The preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments of the present application and the features therein may be combined with each other if there is no conflict.

[0063] To further illustrate the technical solution provided by the embodiment of the present application, this is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiment of the present application provides the method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided by the embodiment of the present application. The method can be executed in the order of the method shown in the embodiment or drawings or in parallel during the actual processing process or when the control device is executed.

[0064] Other features and advantages of the present application will be described in the following description, and partly become apparent from the description, or be understood by practicing the present application. The purpose and other advantages of the present application can be realized and obtained by the structures specifically pointed out in the written description, claims, and drawings.

[0065] In order to facilitate the understanding of this application, the technical terms involved in this application are:

[0066] Mixed light: also known as mixed light, refers to the light obtained by mixing two or more visible lights of different frequencies within a certain visible range, which can meet the needs of various usage scenarios for light sources.

[0067] Optical parameters: parameters that describe the light source, such as color rendering index, color temperature, luminous flux, brightness, etc.

[0068] Color rendering index: used to indicate the color rendering of a light source. The color rendering of a light source refers to the degree to which the light source presents the color of the object itself, that is, the degree of color fidelity. It indicates the degree of deviation of the color of an object under the light source from the color of the reference light (sunlight), and can more comprehensively reflect the color characteristics of the light source. Light sources with high color rendering have better color rendering, and the colors seen by the human eye are close to natural colors; light sources with low color rendering have poorer color rendering, and the color deviation seen by the human eye is also larger. The International Commission on Illumination sets the color rendering index of the sun at 100, and the color rendering index of various light sources is different. For example, the color rendering index of high-pressure sodium lamps is 23, and the color rendering index of fluorescent tubes is 60-90. The higher the color rendering index of a light source, the better the color rendering, and vice versa, the lower the color rendering index, the worse the color rendering.

[0069] Color temperature: expressed in absolute temperature K, that is, a standard black body is heated. When the temperature rises to a certain level, the color begins to gradually change in the order of dark red, light red, orange-yellow, white, and blue. When a light source has the same color as the black body, the absolute temperature of the black body at that time is called the color temperature of the light source.

[0070] Luminous flux: The sum of the visible light emitted by a light source per second, or simply the amount of light emitted. Unit: lumen (lm).

[0071] Figure 1 The application scenario diagram of the mixed light current determination method provided in the embodiment of the present application includes multiple monochromatic light sources 100 and a server 200.

[0072] Multiple monochromatic light sources 100 are used to synthesize mixed light. The monochromatic light sources can be Figure 1 The red light source, green light source, and blue light source shown can of course also be other light sources.

[0073] The server 200 obtains optical parameters of multiple candidate mixed lights, such as color rendering index, color temperature, luminous flux, etc., determines a candidate mixed light that matches the target mixed light from the candidate mixed lights according to the optical parameters of the mixed lights and the optical parameter requirement information of the target mixed light, and finally determines a current value corresponding to the monochromatic light source used to synthesize the target mixed light according to the current values ​​corresponding to the multiple monochromatic light sources included in the selected candidate mixed light. The server may be a single server, a server cluster consisting of several servers, or a cloud computing center.

[0074] Specifically, the server may include a processor 210 (Center Processing Unit, CPU), a memory 220, an input device 230 and an output device 240, etc. The input device 230 may include a keyboard, a mouse, a touch screen, etc., and the output device 240 may include a display device, such as a liquid crystal display (Liquid Crystal Display, LCD), a cathode ray tube (CathodeRay Tube, CRT), etc.

[0075] The memory 220 may include a read-only memory (ROM) and a random access memory (RAM), and provides the processor 210 with program instructions and data stored in the memory 220. In the embodiment of the present application, the memory 220 may be used to store the program of any video audit method in the embodiment of the present application.

[0076] The processor 210 calls the program instructions stored in the memory 220, and the processor 210 is used to execute the steps of any mixed light current determination method in the embodiments of the present application according to the obtained program instructions.

[0077] After introducing the application scenarios of the embodiments of the present application, the current determination method of the mixed light proposed in the present application is described below with a specific embodiment. Figure 2 A flow chart of a method for determining current of mixed light provided in an embodiment of the present application, the method comprising the following steps.

[0078] In step 201, optical parameters of a plurality of first alternative mixed lights are obtained, wherein each first alternative mixed light includes a plurality of different monochromatic light sources, and the current values ​​corresponding to at least one same-color light source included in the different mixed lights are different, and the current values ​​corresponding to the monochromatic light sources are determined based on the current interval length and the operating current range of the monochromatic light sources.

[0079] In a specific implementation, the first alternative mixed light is obtained by mixing multiple different monochromatic light sources, such as R, G, and B light sources. To synthesize a mixed light that meets the requirements, it is usually necessary to continuously adjust the current values ​​of each monochromatic light source. Therefore, different mixed lights include monochromatic light sources that have different current values ​​corresponding to at least one light source of the same color. For example, monochromatic light source 1 with current value 1 and monochromatic light source 2 with current value 2 can be used to synthesize mixed light a, monochromatic light source 1 with current value 1 and monochromatic light source 2 with current value 3 can be used to synthesize mixed light b, mixed light a and mixed light b can be the same type of mixed light or different types of mixed light. Since the change of current affects the change of the spectral energy distribution curve, and the change of the spectral energy distribution curve affects the change of optical parameters, different mixed lights synthesized by monochromatic light sources corresponding to different current values ​​also have different optical parameters, including optical parameters such as luminous flux, color temperature, color rendering index, etc.

[0080] In a specific implementation, the optical parameters of the first candidate mixed light can be determined in the following manner: Figure 3 A flow chart of a method for determining optical parameters of a first candidate mixed light provided in an embodiment of the present application, the method comprising the following steps.

[0081] In step 301, a plurality of monochromatic light sources for synthesizing a target mixed light are determined.

[0082] In specific implementation, the types of monochromatic light sources corresponding to each type of mixed light are selected based on the estimation of the monochromatic light specifications. For example, it is known through experiments that the first type of mixed light can be synthesized by monochromatic light source 1, monochromatic light source 2 and monochromatic light source 3, the second type of mixed light can be synthesized by monochromatic light source 3 and monochromatic light source 4, the third type of mixed light can be synthesized by monochromatic light source 5, monochromatic light source 6 and monochromatic light source 7, etc., wherein the category of mixed light can be divided according to the color of the mixed light or according to other characteristics. The correspondence between each type of mixed light and each monochromatic light source can be created after the experiment. In implementation, if the target mixed light is determined to be the first type of mixed light, the multiple monochromatic light sources corresponding to the first type of mixed light (target mixed light) can be determined from the predetermined correspondence between each type of mixed light and each monochromatic light source.

[0083] In step 302, based on the current interval length and the operating current range of each monochromatic light source, the spectrum of each monochromatic light source under each current parameter is determined, and each current parameter is obtained by dividing the operating current range with the current interval length as a division unit.

[0084] In a specific implementation, each monochromatic light source corresponds to a working current range. For example, the working current range of monochromatic light source 1 is 1A to 9A, the working current range of monochromatic light source 2 is 2A to 12A, and the working current range of monochromatic light source 3 is 2A to 14A. According to the working current range of each monochromatic light source, the same or different current interval lengths can be selected to divide the working current range of each monochromatic light source to obtain different current parameters of each monochromatic light source.

[0085] For example, the current interval length of each monochromatic light source is selected to be 2A, and the current of monochromatic light source 1, monochromatic light source 2 and monochromatic light source 3 are divided, then the current parameter set of monochromatic light source 1 is {1A, 3A, 5A, 7A, 9A}, the current parameter set of monochromatic light source 2 is {2A, 4A, 6A, 8A, 10A, 12A}, and the current parameter set of monochromatic light source 3 is {2A, 4A, 6A, 8A, 10A, 12A, 14A}. According to the current parameters of each monochromatic light source, the spectrum of each monochromatic light source under each current parameter is determined. For example, the corresponding spectrum of monochromatic light source 1 under the current parameters of {1A, 3A, 5A, 7A, 9A} is {spectrum 1, spectrum 2, spectrum 3, spectrum 4, spectrum 5}, the corresponding spectra of the monochromatic light source 2 under the current parameters {2A, 4A, 6A, 8A, 10A, 12A} are {spectrum 6, spectrum 7, spectrum 8, spectrum 9, spectrum 10, spectrum 11}, and the corresponding spectra of the monochromatic light source 3 under the current parameters {2A, 4A, 6A, 8A, 10A, 12A, 14A} are {spectrum 12, spectrum 13, spectrum 14, spectrum 15, spectrum 16, spectrum 17, spectrum 18}. It should be noted that the setting of the current interval length can be determined by technical personnel according to actual needs, wherein the larger the current interval, the fewer current parameters corresponding to the monochromatic light source, and the fewer corresponding spectra; the smaller the current interval, the more current parameters corresponding to the monochromatic light source, and the more corresponding spectra.

[0086] In step 303, first candidate mixed light spectra are determined based on the spectrum of each monochromatic light source under each current parameter.

[0087] In a specific implementation, each first alternative mixed light spectrum can be determined based on the spectrum of each monochromatic light source under each current parameter and the weight corresponding to each spectrum, for example, according to a preset calculation formula for the mixed light spectrum, the calculation formula for the mixed light spectrum is, mixed light spectrum = spectrum of monochromatic light source 1 * weight n + spectrum of monochromatic light source 2 * weight p + spectrum of monochromatic light source 3 * weight q, wherein the weights n, p, q can be the comprehensive transmittance coefficients of the lens and the filter to each monochromatic light source.

[0088] Assume that the monochromatic light sources of the synthetic target mixed light are monochromatic light source 1, monochromatic light source 2 and monochromatic light source 3 respectively, and it is known that the corresponding spectrum of monochromatic light source 1 under current parameters {1A, 3A, 5A} is {spectrum 1, spectrum 2, spectrum 3}, the corresponding spectrum of monochromatic light source 2 under current parameters {2A, 4A, 6A} is {spectrum 4, spectrum 5, spectrum 6}, and the corresponding spectrum of monochromatic light source 3 under current parameters {2A, 4A, 6A} is {spectrum 7, spectrum 8, spectrum 9}. It can be seen that the monochromatic light source 1 has a total of 3 current spectra, the monochromatic light source 2 has a total of 3 current spectra, and the monochromatic light source 3 has a total of 3 current spectra. The spectra of the corresponding first alternative mixed lights of the target mixed light are obtained by combining the spectra of each monochromatic light source, totaling 81 types.

[0089] In step 304, the optical parameters of each first candidate mixed light are determined based on the spectrum of each first candidate mixed light and a preset optical parameter calculation formula.

[0090] In a specific implementation, after obtaining the spectrum of each mixed light, the optical parameter of each first candidate mixed light can be calculated according to the spectrum and a preset optical parameter calculation formula.

[0091] In step 202, based on the optical parameters of the first candidate mixed light and the optical parameter requirement information of the target mixed light, a second candidate mixed light matching the target mixed light is determined from the first candidate mixed light.

[0092] Among them, the optical parameter requirement information of the target mixed light is the requirement index or requirement range for each type of optical parameter. For example, the optical parameter requirement information of the target mixed light is that the luminous flux is not less than 5000lm and the color rendering index parameter is not less than 90 and the color temperature parameter range is [5500, 5700].

[0093] When it comes to specific implementation, Figure 4 A flow chart of a method for determining a second candidate mixed light provided in an embodiment of the present application, the method comprising the following steps.

[0094] In step 401, for any first candidate mixed light, the value corresponding to the optical parameter of the first candidate mixed light of the same type is compared with the optical parameter requirement information in the optical parameter requirement information.

[0095] Taking the optical parameters of each type as luminous flux, color rendering index and color temperature, and the optical parameter requirement information of the target mixed light as luminous flux not less than 5000lm, color rendering index parameter not less than 90, and color temperature parameter range [5500, 5700] as an example, assuming that there are three first alternative mixed lights, namely first alternative mixed light 1, first alternative mixed light 2 and first alternative mixed light 3, and the optical parameter information of each type of the first alternative mixed light 1, the first alternative mixed light 2 and the first alternative mixed light 3 is shown in Table 1.

[0096] Table 1

[0097]

[0098]

[0099] It can be seen from Table 1 above that, for the first alternative mixed light 1, the value corresponding to the luminous flux of the first alternative mixed light 1 can be compared with the value corresponding to the luminous flux in the optical parameter requirement information, the value corresponding to the color rendering index of the first alternative mixed light 1 can be compared with the value corresponding to the color rendering index in the optical parameter requirement information, and the value corresponding to the color temperature of the first alternative mixed light 1 can be compared with the range of values ​​corresponding to the color temperature in the optical parameter requirement information. The first alternative mixed light 2 is similar to the first alternative mixed light 3 and will not be repeated here.

[0100] In step 402, based on the comparison results of various types of optical parameters, evaluation parameters of each first candidate mixed light are determined.

[0101] In a specific implementation, based on the comparison results of various types of optical parameters, the evaluation parameters of various types of optical parameters of the first candidate mixed light may be first determined using a preset mixed light quality evaluation rule.

[0102] The preset mixed light quality evaluation rule may include any one or more combinations of the following.

[0103] The first type: if the value corresponding to any type of optical parameter in any mixed light meets the required value of the optical parameter of the same type in the optical parameter requirement information, then the evaluation parameter of the optical parameter of this type is determined to be the first evaluation value, otherwise it is the second evaluation value;

[0104] The second type: if the value corresponding to any type of optical parameter in any mixed light is within the requirement range of the optical parameter of the same type in the optical parameter requirement information, then the evaluation parameter of this type of optical parameter is determined to be the first evaluation value, otherwise it is the second evaluation value; wherein the first evaluation value is higher than the second evaluation value, for example, the first evaluation value is set to 100 and the second evaluation value is set to 0.

[0105] The third type: for any type of optical parameter in any mixed light, the difference between the value corresponding to the optical parameter and the required value of the corresponding type of optical parameter in the optical parameter requirement information is determined as the evaluation parameter of the optical parameter of this type.

[0106] For example, in the above Table 1, after comparing the values ​​corresponding to each type of optical parameter of the first alternative mixed light 1 with the requirement information of the optical parameters in the optical parameter requirement information, it can be known that the comparison results of each type of optical parameters are: the luminous flux of the first alternative mixed light 1 is less than the value of the luminous flux in the requirement information of the optical parameters, the color rendering index of the first alternative mixed light 1 is less than the value of the color rendering index in the requirement information of the optical parameters, and the color temperature of the first alternative mixed light 1 satisfies the parameter range of the color temperature in the requirement information of the optical parameters. According to the preset mixed light quality evaluation rule, if the evaluation rule of the luminous flux is the first type, the evaluation rule of the color temperature is the second type, and the evaluation rule of the color rendering index is the third type, then the evaluation parameters of each type of optical parameter of the first alternative mixed light 1 can be determined as follows: the evaluation parameter of the luminous flux is 0, the evaluation parameter of the color rendering index is negative 1, and the evaluation parameter of the color temperature is 100. Similarly, the evaluation parameters corresponding to each type of optical parameter of the first alternative mixed light 2 and the first alternative mixed light 3 can also be determined in the above manner, as shown in Table 2.

[0107] Table 2

[0108]

[0109] In specific implementation, after determining the evaluation parameters of each type of optical parameter, the evaluation parameters of the first alternative mixed light can be determined according to a preconfigured evaluation function, wherein the preconfigured evaluation function can be set by a technician. For example, the sum of the evaluation parameters of each type of optical parameter is determined as the evaluation parameter of the first alternative mixed light. It can be seen from Table 2 above that the evaluation parameter of the first alternative mixed light 1 is 99, the evaluation parameter of the first alternative mixed light 2 is 200, and the evaluation parameter of the first alternative mixed light 3 is 101.

[0110] In step 403 , based on the evaluation parameters of the first candidate mixed lights, a second candidate mixed light matching the target mixed light is selected from the first candidate mixed lights.

[0111] In a specific implementation, the second candidate mixed light may be a second candidate mixed light that matches the target mixed light by determining the first candidate mixed light having the highest evaluation parameter among the first candidate mixed lights.

[0112] In step 203, based on the current values ​​corresponding to the multiple monochromatic light sources included in the second candidate mixed light, the current value corresponding to the monochromatic light source used to synthesize the target mixed light is determined.

[0113] In specific implementation, after determining the second alternative mixed light, the spectrum of each monochromatic light source that synthesizes the spectrum corresponding to the second alternative mixed light can be determined from the second alternative mixed light, and the current value of the monochromatic light source corresponding to the spectrum can be determined from the spectrum of each monochromatic light source, and the current value corresponding to each monochromatic light source is determined as the current value corresponding to the monochromatic light source used to synthesize the target mixed light.

[0114] During specific implementation, the operating current of each monochromatic light source may also be adjusted according to the current value, so that each monochromatic light source synthesizes the target mixed light according to the corresponding current value.

[0115] The embodiments of the present application can automatically adjust the current of each monochromatic light source of the target mixed light without the need for manual adjustment one by one, thereby improving the speed of determining the current of each monochromatic light source of the mixed light and saving a lot of manpower and material resources. At the same time, the mixed light obtained by synthesizing each monochromatic light source according to its own determined current has a better effect.

[0116] In practical applications, if the spectra of each monochromatic light source under different current parameters of the synthesized target mixed light are large, and the number of monochromatic light sources is also large, then the number of synthesized first candidate mixed lights is large, and the corresponding mixed light spectra and optical parameters of the mixed light are large. The amount of calculation of the evaluation parameters of each candidate mixed light according to the optical parameter requirement information of the target mixed light will be large. Therefore, in order to reduce the amount of calculation and further improve the speed of determining the current of each monochromatic light source of the mixed light, Figure 5 A flowchart of another method for determining a second candidate mixed light provided in an embodiment of the present application, the method comprising the following steps.

[0117] In step 501, multiple rounds of screening are performed on the first candidate mixed light based on multiple different monochromatic light sources, and each round includes multiple screening processes. The number of screening rounds and the number of screening times are determined according to the number of multiple different monochromatic light sources and the current value corresponding to each monochromatic light source.

[0118] In step 502, for any screening process of any round, based on the current values ​​corresponding to each monochromatic light source in the predetermined combinations of different screening round numbers and screening times, the current values ​​corresponding to each monochromatic light source in this round of screening are determined, and multiple third alternative mixed lights are screened out from the first alternative mixed lights.

[0119] In specific implementation, the current value corresponding to each monochromatic light source in the combination of different screening rounds and screening times can be determined by the following method: Figure 6 A flow chart of a method for determining current values ​​corresponding to each monochromatic light source in combinations of different screening round numbers and screening times provided in an embodiment of the present application, the method comprising the following steps.

[0120] In step 601 , based on the number of each monochromatic light source, the number of the first light source, the second light source and the third light source in each monochromatic light source is determined respectively.

[0121] Among them, the number of first light sources is 1, the number of third light sources is 1, and the number of second light sources is the difference between the number of each monochromatic light source and the number of the first light source and the number of the third light source. For example, when the number of each monochromatic light source is 2, the number of first light sources is 1, the number of third light sources is 1, and the number of second light sources is 0; when the number of each monochromatic light source is 3, the number of first light sources is 1, the number of third light sources is 1, and the number of second light sources is 1, and so on.

[0122] In step 602, based on the current values ​​corresponding to the first light source, the second light source and the third light source, the current values ​​corresponding to the first light source, the second light source and the third light source are sorted in order from small to large.

[0123] In a specific implementation, after determining the number of the first light source, the second light source and the third light source in each monochromatic light source, the current values ​​corresponding to the first light source, the second light source and the third light source may be sorted in ascending order.

[0124] For example, taking the example that the number of the first light source, the second light source and the third light source are all 1, and the current values ​​of the first light source are {1A, 3A, 5A, 7A, 9A}, the current values ​​of the second light source are {2A, 4A, 6A, 8A, 10A}, and the current values ​​of the third light source are {3A, 5A, 7A, 9A, 11A}, then the current values ​​corresponding to the first light source, the second light source and the third light source are sorted in order from small to large, and the sorting results shown in Table 3 can be obtained.

[0125] Table 3

[0126]

[0127]

[0128] In step 603, a first corresponding relationship between each current value of the second light source after sorting and the number of screening rounds is established, and a second corresponding relationship between each current value of the third light source after sorting and the number of screening rounds is established.

[0129] In specific implementation, the ranking of each current value after sorting of the second light source can be corresponded one by one to the number of screening rounds, as shown in Table 3 above, 2A, which has the first current value ranking among the second light sources, corresponds to the first screening round, 4A, which has the second current value ranking among the second light sources, corresponds to the second screening round, and so on, to establish a first corresponding relationship, and the obtained first corresponding relationship is shown in Table 4.

[0130] Table 4

[0131] Second light source Number of screening rounds 2A First round 4A Round 2 6A Round 3 8A Round 4 10A Fifth round

[0132] In specific implementation, the ranking of each current value after sorting of the third light source can be corresponded one by one with the number of screening times, as shown in Table 3 above, 3A, which has the first current value ranking among the third light source, corresponds to the first number of screening times, 5A, which has the second current value ranking among the third light source, corresponds to the second number of screening rounds, and so on, to establish a second corresponding relationship, and the obtained second corresponding relationship is shown in Table 5.

[0133] Table 5

[0134] The third light source Screening times 3A first 5A Second time 7A The third time 9A Fourth 11A Fifth

[0135] In step 604, based on the first correspondence, the second correspondence and the sorted current values ​​of the first light source, the current values ​​corresponding to each monochromatic light source in the combinations of different screening rounds and screening times are determined, wherein the current value corresponding to the first light source in the combinations of different screening rounds and screening times is all the current values ​​corresponding to the first light source.

[0136] In specific implementation, each round includes multiple screening processes, and different rounds and different times have different combinations. For example, if the number of second light sources is 1 and the current value of the second light source is 2, then the number of screening rounds is 2. If the current value of the third light source is 5, then it can be determined that the number of screening times in each round is 5. Therefore, there are a total of 10 screening combinations. If the number of second light sources is 2 and the current value of each second light source is 2, then the number of screening rounds is 4. If the current value of the third light source is 5, then it can be determined that the number of screening times in each round is 5. Therefore, there are a total of 20 screening combinations.

[0137] In specific implementation, taking the case where the number of the first light source, the second light source and the third light source are 1 respectively, and the current value of the first light source is sorted as {1A, 2A, 3A}, the current value of the second light source is {2A, 4A}, the current value of the third light source is {3A, 5A, 7A}, the first corresponding relationship is 2A corresponding to the first round, 4A corresponding to the second round, the second corresponding relationship is 3A corresponding to the first time, 5A corresponding to the second time, and 7A corresponding to the third time as an example, the combinations of different screening rounds and screening times are the first time of the first round, the second time of the first round, the third time of the first round, the first time of the second round, the second time of the second round and the third time of the second round. The current values ​​corresponding to the first light source in the combinations of different screening rounds and screening times are all the current values ​​corresponding to the first light source. Therefore, the current values ​​corresponding to each monochromatic light source in the determined combinations of different screening rounds and screening times are as shown in Table 6.

[0138] Table 6

[0139]

[0140]

[0141] Assuming that as shown in Table 6 above, if the current screening round number is the first round and the current screening number is the second time, it can be determined that the current value corresponding to the first light source in the current screening process is 1A, 2A, 3A, the current value corresponding to the second light source is 2A, and the current value corresponding to the third light source is 3A. Then, multiple third alternative mixed lights can be screened out from the first alternative mixed light, wherein the current value corresponding to the first light source in each third alternative mixed light is any one of 1A, 2A, and 3A, the current value corresponding to the second light source is 2A, and the current value corresponding to the third light source is 3A.

[0142] In step 503, a target third candidate mixed light is determined from the screened plurality of third candidate mixed lights.

[0143] During specific implementation, for any third alternative mixed light, the values ​​corresponding to the optical parameters of the same type of third alternative mixed light are compared with the requirement information of the optical parameters in the optical parameter requirement information, and based on the comparison results of each type of optical parameters, the evaluation parameters of each third alternative mixed light are determined; based on the evaluation parameters of each third alternative mixed light, the target third alternative mixed light is determined from the third alternative mixed lights.

[0144] In specific implementation, the screened third candidate mixed lights may be sorted in ascending order according to the current value of the first light source. For example, the screening results are shown in Table 7.

[0145] Table 7

[0146] The third alternative mixed light First light source Second light source The third light source Third alternative mixed light 1 1A 2A 3A Third alternative mixed light 2 2A 2A 3A Third alternative mixed light 3 3A 2A 3A

[0147] As shown in Table 7 above, the evaluation parameters of each third alternative mixed light can be calculated in sequence. When the evaluation parameters of any third alternative mixed light are calculated, the evaluation parameters of the current third alternative mixed light are compared with the evaluation parameters of the previous third alternative mixed light. If the evaluation parameters of the current third alternative mixed light are higher than the evaluation parameters of the previous third alternative mixed light, the calculation continues. If the evaluation parameters of the current third alternative mixed light are lower than the evaluation parameters of the previous third alternative mixed light, the calculation of the evaluation parameters of the remaining third alternative mixed lights is stopped. This can also reduce the amount of calculation to a certain extent.

[0148] In step 504, for any screening process, the evaluation parameters of the target third alternative mixed light screened out this time are compared with the evaluation parameters of the target third alternative mixed light screened out last time. If the evaluation parameters of the target third alternative mixed light screened out this time are higher than the evaluation parameters of the target third alternative mixed light screened out last time, the next screening process will continue until the evaluation parameters of the target third alternative mixed light screened out at any time are lower than the corresponding evaluation parameters of the target third alternative mixed light screened out last time, then the next screening process will be stopped, the third alternative mixed light screened out last time will be determined as the fourth alternative mixed light, and the next round of screening process will be executed.

[0149] In specific implementation, for example, the number of screenings in the first round is 5 times, the evaluation parameter of the target third alternative mixed light screened out in the first screening is 200, and the evaluation parameter of the target third alternative mixed light screened out in the second screening is 201, and it can be determined that 201 is greater than 200, so the next screening process is continued, and the evaluation parameter of the target third alternative mixed light screened out for the third time is observed. If the evaluation parameter of the target third alternative mixed light screened out for the third time is 202, the next screening process is continued. If the evaluation parameter of the target third alternative mixed light screened out for the third time is 200, the change trend of the evaluation parameter is gradually decreasing, and therefore there is no need to continue the next screening process, and the target third alternative mixed light screened out for the second time is determined as the fourth alternative mixed light, and the next round of screening process is executed.

[0150] In step 505, when any round of screening process ends, the evaluation parameters of the fourth candidate mixed light in this round are compared with the evaluation parameters of the fourth candidate mixed light in the previous round. If the evaluation parameters of the fourth candidate mixed light screened out in this round are higher than the evaluation parameters of the fourth candidate mixed light screened out in the previous round, the next round of screening process will continue to be executed until the evaluation parameters of the fourth candidate mixed light screened out in any round are lower than the corresponding evaluation parameters of the fourth candidate mixed light screened out in the previous round, then the next round of screening process will be stopped, and the fourth candidate mixed light screened out in the previous round will be determined as the second candidate mixed light matching the target mixed light.

[0151] In specific implementation, if the evaluation parameter of the fourth alternative mixed light screened out in this round is higher than the evaluation parameter of the fourth alternative mixed light screened out in the previous round, it means that the second alternative mixed light that best matches the target mixed light has not been found, and the next round of screening process will continue to be executed; if the evaluation parameter of the fourth alternative mixed light screened out in any round is lower than the evaluation parameter of the corresponding fourth alternative mixed light screened out in the previous round, it means that the fourth alternative mixed light in this round has deviated from the requirement of the target mixed light, and the next round of screening process will be stopped, and the fourth alternative mixed light screened out in the previous round will be determined as the second alternative mixed light that matches the target mixed light.

[0152] In this way, there is no need to calculate the evaluation parameters of all the first candidate mixed lights. The trend changes of the evaluation parameters of the screened mixed lights are observed during each screening. When the trend of change increases, the calculation is continued, and when the trend of change decreases, the calculation is stopped. In each round of screening, the trend changes of the evaluation parameters of the screened mixed lights are observed. When the trend of change increases, the calculation is continued, and when the trend of change decreases, the calculation is stopped. In this way, the second candidate mixed light that matches the target mixed light can be quickly screened out, the amount of calculation is reduced, and the speed of determining the current of each monochromatic light source of the mixed light is further improved.

[0153] Figure 7 A flow chart of another method for determining current of mixed light provided in an embodiment of the present application, the method comprising the following steps.

[0154] In step 701, a plurality of monochromatic light sources for synthesizing a target mixed light are determined.

[0155] In step 702, based on the current interval length and the operating current range of each monochromatic light source, the spectrum of each monochromatic light source under each current parameter is determined, and each current parameter is obtained by dividing the operating current range with the current interval length as a division unit.

[0156] In step 703, first candidate mixed light spectra are determined based on the spectrum of each monochromatic light source under each current parameter.

[0157] In step 704, the optical parameters of each first candidate mixed light are determined based on the spectrum of each first candidate mixed light and a preset optical parameter calculation formula.

[0158] In step 705, for any first candidate mixed light, the value corresponding to the optical parameter of the first candidate mixed light of the same type is compared with the optical parameter requirement information in the optical parameter requirement information.

[0159] In step 706 , based on the comparison results of the various types of optical parameters, evaluation parameters of each first candidate mixed light are determined.

[0160] In step 707 , based on the evaluation parameters of the first candidate mixed lights, a second candidate mixed light matching the target mixed light is selected from the first candidate mixed lights.

[0161] In step 708, based on the current values ​​corresponding to the multiple monochromatic light sources included in the second candidate mixed light, the current value corresponding to the monochromatic light source used to synthesize the target mixed light is determined.

[0162] Figure 8 A flow chart of another method for determining current of mixed light provided in an embodiment of the present application, the method comprising the following steps.

[0163] In step 801, a plurality of monochromatic light sources for synthesizing a target mixed light are determined.

[0164] In step 802, based on the current interval length and the operating current range of each monochromatic light source, the spectrum of each monochromatic light source under each current parameter is determined, and each current parameter is obtained by dividing the operating current range with the current interval length as a division unit.

[0165] In step 803, first candidate mixed light spectra are determined based on the spectrum of each monochromatic light source under each current parameter.

[0166] In step 804, the optical parameters of each first candidate mixed light are determined based on the spectrum of each first candidate mixed light and a preset optical parameter calculation formula.

[0167] In step 805, multiple rounds of screening are performed on the first candidate mixed light based on multiple different monochromatic light sources, and each round includes multiple screening processes. The number of screening rounds and the number of screening times are determined according to the number of multiple different monochromatic light sources and the current value corresponding to each monochromatic light source.

[0168] In step 806, based on the current values ​​corresponding to each monochromatic light source in the predetermined combinations of different screening rounds and screening times, the current values ​​corresponding to each monochromatic light source in this round of screening are determined, and multiple third alternative mixed lights are screened out from the first alternative mixed lights.

[0169] In step 807 , a target third candidate mixed light is determined from the screened plurality of third candidate mixed lights.

[0170] In step 808 , for any screening process, the evaluation parameters of the target third candidate mixed light screened this time are compared with the evaluation parameters of the target third candidate mixed light screened last time.

[0171] In step 809 , it is determined whether the evaluation parameter of the target third candidate mixed light screened this time is higher than the evaluation parameter of the target third candidate mixed light screened last time. If so, the process proceeds to step 806 ; if not, the process proceeds to step 810 .

[0172] In step 810, the next screening process is stopped, and the third candidate mixed light screened last time is determined as the fourth candidate mixed light.

[0173] In step 811, for any round of screening process, the evaluation parameters of the fourth candidate mixed light in this round are compared with the evaluation parameters of the fourth candidate mixed light in the previous round.

[0174] In step 812 , it is determined whether the evaluation parameter of the fourth candidate mixed light screened in this round is higher than the evaluation parameter of the fourth candidate mixed light screened in the previous round. If so, the process proceeds to step 806 to execute the next round of screening process. If not, the process proceeds to step 813 .

[0175] In step 813, the next round of screening process is stopped, and the fourth candidate mixed light screened in the previous round is determined as the second candidate mixed light matching the target mixed light.

[0176] Based on the same technical concept, an embodiment of the present application also provides a current determination device for mixed light. The principle of solving the problem by the current determination device for mixed light is similar to that of the above-mentioned current determination method for mixed light. Therefore, the implementation of the current determination device for mixed light can refer to the implementation of the current determination method for mixed light, and the repeated parts will not be repeated.

[0177] Fig. 9 A schematic structural diagram of a mixed light current determination device provided in an embodiment of the present application includes an acquisition module 901 , a first determination module 902 , and a second determination module 903 .

[0178] An acquisition module 901 is used to acquire optical parameters of a plurality of first candidate mixed lights; wherein each of the first candidate mixed lights includes a plurality of different monochromatic light sources, and at least one monochromatic light source of the same color included in the different mixed lights has a different current value corresponding to it, and the current value corresponding to the monochromatic light source is determined based on the current interval length and the operating current range of the monochromatic light source;

[0193] At the end of any round of screening process, the evaluation parameters of the fourth alternative mixed light in this round are compared with the evaluation parameters of the fourth alternative mixed light in the previous round.
