[0056] The embodiments of the technical solution of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present application more clearly, and therefore are only examples and cannot be used to limit the protection scope of the present application.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the description of the specification, claims and drawings of this application are intended to cover non-exclusive inclusion.

[0058] In the description of the embodiments of the present application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary-secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "a plurality" is two or more (including two), unless otherwise specifically defined.

[0059] Referring to "embodiments" herein means that specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0060] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B, which can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0061] When mixing white light with traditional RGB light sources, if a certain light source efficiency is to be ensured, the color rendering index (CRI) is usually only around 80; and if the color rendering index (CRI) is to reach above 90, the light source efficiency will significantly decrease, making it difficult to achieve maximum efficiency. This problem is more obvious in the color temperature range of 2000 - 10000K. It can be seen that the existing methods have problems such as insufficient color rendering index (CRI) or poor color uniformity.

[0062] At the same time, traditional RGB light sources are prone to color deviation and light spots during mixing, affecting the lighting quality. When specifically used for large - area illumination in stage lighting, the problems of color difference and bright spots are more obvious.

[0063] To address the above - mentioned technical problems, the embodiments of the present application provide a method for arranging light sources of a multi - color light source module. This method can first divide the color temperature range to be arranged into a low - color - temperature section and a high - color - temperature section, and respectively determine the corresponding auxiliary color sets for these two color temperature sections according to the requirements of maximizing light source efficiency and maximizing color rendering index. Then, based on preset parameters and the determined color sets, the number of light sources of each color is proportioned, and according to the layout principle of the optimal mixing effect, the light sources of each color are evenly arranged to obtain a multi - color light source module.

[0064] It can be seen that this method can solve the problems of insufficient color rendering and poor color uniformity of traditional RGB light sources. Thus, it is beneficial to achieve a more uniform mixing effect, so that when it is applied to the large - area illumination scenario of stage lighting, obvious color differences and bright spots will not appear, thereby improving the lighting quality and stability.

[0065] As Figure 1 shown, some embodiments of the present application provide a method for arranging light sources of a multi - color light source module. The method for arranging light sources of the multi - color light source module includes:

[0066] S101. Divide the color segment range to be arranged to obtain a low - color - temperature section and a high - color - temperature section.

[0067] S102. Determine the first auxiliary color set corresponding to the low - color - temperature section and the second auxiliary color set corresponding to the high - color - temperature section according to the requirements of maximizing light source efficiency and maximizing color rendering index.

[0068] S103. Based on the preset maximum target brightness, the preset multi - color light source white - light mixing power, the requirement of maximizing color rendering index, the preset basic color set, the first auxiliary color set and the second auxiliary color set, proportion the number of light sources of each color to obtain the number of light sources of each color.

[0069] S104. Based on the preset layout principle of the optimal mixing effect and the number of light sources of each color, arrange the light sources to obtain a uniformly distributed multi - color light source module.

[0070] In some embodiments, the range of the color segments to be arranged can be 2000K - 10000K.

[0071] In some embodiments, the light source efficiency refers to the efficiency of the light source in converting electrical energy into visible light, that is, the ratio of the luminous flux emitted by the light source to the electrical power consumed by it.

[0072] In some embodiments, the color rendering index is a metric for measuring the ability of a light source to present the true color of an object. The higher the value, the closer the light source is to restoring the natural color of the object.

[0073] In some embodiments, both the first auxiliary color set and the second auxiliary color set can include one color or multiple colors, and there are no identical colors in the two sets.

[0074] In some embodiments, the maximum target brightness refers to the preset maximum target brightness.

[0075] In some embodiments, the multi - color light source mixed white light power refers to the preset mixed white light power.

[0076] In some embodiments, the basic color set is the three primary colors RGB, that is, the three primary colors of red, green, and blue.

[0077] In some embodiments, the ratio of the number of light sources can be a relationship between multiple numerical values or a ratio relationship between multiple numerical values.

[0078] In these embodiments, the method can scientifically divide a suitable color temperature range, optimize the selection of auxiliary colors, accurately match the number of light sources, and arrange the light sources optimally according to the optimal mixed - light arrangement principle, so as to achieve the efficient and high - quality arrangement of the multi - color light source module.

[0079] In order to obtain the auxiliary colors more accurately, in some embodiments, according to the requirements of maximizing the light source efficiency and maximizing the color rendering index, determining the first auxiliary color set corresponding to the low color temperature range and the second auxiliary color set corresponding to the high color temperature range, includes:

[0080] According to the requirements of maximizing the light source efficiency and maximizing the color rendering index, determining in the low color temperature range of 2000K to 6000K the first auxiliary color set including amber auxiliary color and lemon - green auxiliary color;

[0081] According to the requirements of maximizing the light source efficiency and maximizing the color rendering index, determining in the high color temperature range of 6000K to 10000K the second auxiliary color set including light - blue auxiliary color and cyan auxiliary color.

[0082] In some embodiments, the low color temperature range can be selected as 2000K - 6000K.

[0083] In some embodiments, the high color temperature range can be selected as 6000K - 10000K.

[0084] In some embodiments, the auxiliary colors of amber (A) and lemon green (L) can be determined within the range of 2000K - 6000K.

[0085] In some embodiments, the auxiliary colors of light blue (H) and cyan (C) can be determined within the range of 6000K - 10000K.

[0086] Exemplarily, in the test of 2000K - 10000K, by adding two auxiliary colors of A (amber) and L (lemon green), the light source efficiency and color rendering index in the color temperature range of 2000K - 6000K can be improved; meanwhile, by adding two auxiliary colors of H (light blue) and C (cyan), the light source efficiency and color rendering index in the color temperature range of 6000K - 10000K can be improved.

[0087] Among them, the final data of the color matching test shows that: when mixing white light, the utilization rate of the light source efficiency can be increased to more than 75%; meanwhile, the color rendering index can be increased to more than 90.

[0088] In these embodiments, the method can adopt amber color with lower power consumption to reduce the overall energy consumption without affecting the brightness; meanwhile, using colors such as lemon green and light blue can effectively make up for the deficiencies of traditional RGB in terms of brightness and color performance, and is suitable for lighting in large theaters, opera houses and other places, so as to achieve the balance between brightness and energy saving.

[0089] In order to achieve a better light source arrangement effect, in some embodiments, the optimal arrangement principles for the mixed light effect include the principle of symmetrical distribution in the up - down, left - right directions, the 45 - degree line symmetry principle, the light density symmetry principle, and the principle of minimizing the light source gap.

[0090] In some embodiments, the principle of symmetrical distribution in the up - down, left - right directions means that the light sources are arranged in a mirror - symmetrical manner with the center point as the reference in the horizontal and vertical directions. Among them, this principle is beneficial to ensuring the uniform diffusion of light in the horizontal and vertical directions, avoiding local color deviation caused by asymmetrical arrangement. At the same time, it is also beneficial to reducing the difficulty of optical compensation and improving the mixed light efficiency.

[0091] In some embodiments, the 45 - degree line symmetry principle means that the light sources are symmetrically distributed in the diagonal directions of 45 degrees, 135 degrees, 225 degrees, 315 degrees, etc. Among them, this principle is beneficial to making up for the deficiency of the mixed light in the diagonal view under simple horizontal / vertical symmetry, and at the same time reducing the color patches or brightness differences during diagonal observation. In addition, it is also beneficial to enhancing the spatial uniformity, making it applicable to scenarios that require uniform lighting in all directions.

[0092] In some embodiments, the principle of optical density symmetry refers to the principle of symmetrically adjusting the distribution density of different color light sources according to the light flux contribution in the light source arrangement, so as to ensure that the light flux output per unit area in all directions is consistent. Among them, through this principle, the color rendering property and brightness can be balanced to maintain the overall optical density balance. At the same time, local overexposure or underexposure is avoided, and the light spots or dark areas after light mixing are reduced.

[0093] In some embodiments, the principle of minimizing the light source gap refers to the principle of minimizing the physical distance between light sources as much as possible under the conditions of meeting heat dissipation, electrical safety, etc. Among them, this principle is beneficial to reducing the light diffusion path, enabling the light of different color light sources to be mixed faster, and shortening the light mixing distance. At the same time, the space utilization rate is improved, enabling it to increase the number of light sources within a limited module area and enhancing the light output ability.

[0094] In these embodiments, the method can adopt a uniform mixing and pasting method to determine the arrangement of multi-color light sources, so that when combining brightness, color rendering index, and mixed white light, the number of light sources and their distribution can be obtained to maximize the light efficiency.

[0095] In order to better complete the light source arrangement, in some embodiments, based on the preset principle of optimal arrangement for light mixing effect and the number of light sources of each color, the light source arrangement is carried out to obtain a uniformly distributed multi-color light source module, including:

[0096] Based on the preset basic color set, the first auxiliary color set, and the second auxiliary color set, determine the color order to be arranged starting from the red light in the basic color set;

[0097] In a circular space with a preset diameter, uniformly distribute the red light sources according to the preset principle of optimal arrangement for light mixing effect and the number of red light sources to obtain the red light arrangement result;

[0098] Based on the color order to be arranged, the principle of optimal arrangement for light mixing effect, the number of light sources of each color, and the red light arrangement result, closely arrange each color light source one by one until all color light sources are arranged to obtain the multi-color light arrangement result;

[0099] Based on the multi-color light arrangement result, determine a uniformly distributed multi-color light source module.

[0100] Exemplarily, the method can uniformly distribute in a circular space with a diameter of 25MM, starting from the red light according to the principle of optimal arrangement for light mixing effect and the calculated number of light sources; then after determining the position of the red (R) light, closely arrange in the order of GBHLAC and the principle of optimal arrangement for light mixing effect to obtain a uniformly distributed 7-color light source module.

[0101] Please refer to Figure 2 , Figure 2Shows an arrangement schematic diagram of a 7-color light source module. Among them, Figure 2 Shows the staggered arrangement of RGBHALC.

[0102] In some embodiments, the method can follow the principle of optimal arrangement for the light mixing effect, including the principles of symmetry in the up-down, left-right directions, 45-degree line symmetry, light density symmetry, and minimizing the light source gap. Starting from the red light in sequence, the 7-color light sources of RGBHLAC are evenly and closely distributed within a circular space with a set diameter of 25 mm, thereby obtaining the final 7-color light source module.

[0103] In these embodiments, the method can utilize the mutual complementation and adjustment of the light distribution, making the emitted light more uniform throughout the illumination area, which is beneficial to reducing the brightness difference and color deviation, and improving the illumination quality and stability.

[0104] In order to refine the composition of the multi-color light source module, in some embodiments, the number of light sources of each color includes:

[0105] 10 red light sources, 8 green light sources, 5 blue light sources, 5 light blue light sources, 10 amber light sources, 10 lime green light sources, and 5 cyan light sources.

[0106] In some embodiments, the method can perform the light source number ratio based on the preset maximum target brightness, the mixed white light power of the RGBHALC 7-color light sources, and the requirement of maximizing the color rendering index, so as to obtain the number of light sources of each color.

[0107] Exemplarily, after setting the maximum target brightness of the light source for the 7-color light source module, according to the mixed white light power of the 7-color light sources and the ratio of maximizing the color rendering index, the ratio of each color can be obtained as follows: 10 for R (red), 8 for G (green), 5 for B (blue), 5 for H (light blue), 10 for A (amber), 10 for L (lime green), and 5 for C (cyan), with a total of 53.

[0108] In these embodiments, the method can effectively reduce the color deviation and light spots by staggering the arrangement of the 7 colors of RGBHALC, achieving a uniform light mixing effect. When the stage light is irradiated over a large area, obvious color differences and bright spots can also be avoided.
