[0037] In order to make the purposes, technical solutions and advantages of the embodiments clearer, the technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0038] Software Define Lighting (SDL) lamp beads are currently used in area light sources as a kind of high-value, wide-color gamut lamp beads. The present embodiment aims to meet the uniformity requirements of a certain single color light and the uniformity requirements of multi-color mixing for multi-color lamp beads, and needs to match the requirements of the power supply drive. The number of lamp beads is large, so the arrangement is difficult, the arrangement cycle is long, the uniformity is not high, the design cycle is long, and it is difficult to meet the requirements of single color and multi-color at the same time.

[0039] To solve the above problems, the present embodiment provides a multi-color LED unit arrangement method, device and equipment, which solves the problems of difficulty in meeting the requirements of multi-color and single-color uniformity for multi-color LED, large number of lamp beads, long arrangement design cycle and low timeliness.

[0040] The implementation scheme of the present embodiment will be described below. Figures 1 to 8 The implementation scheme of the present embodiment will be described below.

[0041] Figure 1 As shown in the flowchart of the multi-color LED unit arrangement method provided by the present embodiment, the method can include the following steps:

[0042] 100: initialize the area of the multi-color LED unit, and determine the precision range of the multi-color LED unit area.

[0043] Specifically, as shown in the flowchart of the further multi-color LED unit arrangement method provided by the present embodiment, the method includes Step1-Step8, which will be described in detail below. Figure 2 As shown in the flowchart of the further multi-color LED unit arrangement method provided by the present embodiment, the method includes Step1-Step8, which will be described in detail below.

[0044] Step1 can be completed by Step1 of the present embodiment.

[0045] Step1: select a suitable area unit S and determine its precision range [S1, S2].

[0046] By determining the appropriate area unit occupied by a single LED unit (such as an LED lamp bead), it can be ensured that the arrangement of LED units meets both the uniformity of single color and the uniformity of multi-color mixing. At the same time, the range of the area unit is determined to ensure the accuracy and consistency of the LED arrangement. By setting the area unit S occupied by the lamp bead and the accuracy range, it can adapt to the demand of LED arrangement of different sizes and accuracy, and improve the flexibility and applicability of the design.

[0047] 200: Obtain the radial increment of the current arrangement array, and determine the radius of the current arrangement array according to the radial increment.

[0048] Specifically, the steps of this embodiment can be completed by Step2.

[0049] Step2: Take the radial increment δr of the arrangement array, and calculate its radius r i , where r i = r i-1 + δr.

[0050] Taking a circular lamp as an example, its arrangement mode is to arrange the lamp beads from the inner ring to the outer ring one by one. Wherein the radial increment δr is the radius length increased by the current arrangement array compared with the last arrangement array, and i is the arrangement order of the current arrangement array from the inner ring to the outer ring on the circular lamp.

[0051] By taking the radial increment δr, and updating the radius r i (r i = r i-1 + δr), the accurate control of the radial position of LED arrangement is realized. This is the basis for constructing circular or annular LED arrangement mode, which ensures that the position of each LED unit in the radial direction is determined according to a certain increment. The value of δr can be adjusted according to specific requirements, so as to change the radial spacing between LED units. This flexibility makes the design scheme adapt to the requirements of LED arrangement of different sizes and densities. Through the uniform radial increment δr, it can be ensured that the distribution of LED units in the radial direction is uniform, which helps to improve the overall beauty and consistency of display effect of LED arrangement. For the consumption of computing resources, this incremental method can simplify the calculation process, making the algorithm more efficient and easy to implement. At the same time, it also provides convenience for the calculation of the circumferential interval length, the number of LED units and other subsequent steps.

[0052] 300: Determine the interval angle of the circumferential direction of the multi-color LED unit according to the radial increment and the radius.

[0053] Specifically, the steps of this embodiment can be completed by Step3-Step5.

[0054] Optionally, the interval angle of the multi-color LED unit in the circumferential direction is determined according to the radial increment and the radius, specifically including: determining the interval length of the multi-color LED unit in the circumferential direction according to the radial increment, and determining the circumference of the current arrangement array according to the radius; determining the number of multi-color LEDs according to the interval length and the circumference; and determining the interval angle of the multi-color LED unit in the circumferential direction according to the number of multi-color LEDs.

[0055] Specifically, Step 3: calculating the interval length δL of the multi-color LED unit in the circumferential direction i and the circumference C i of the current arrangement array. Wherein, the interval length δL of the circumferential direction i =S / δr, and the circumference C i =2*π*r i .

[0056] Step 4: calculating the number N of multi-color LED units i .

[0057] Step 5: calculating the interval angle δθ of the multi-color LED unit in the circumferential direction i , wherein the interval angle δθ i =2*π / N i .

[0058] Through the detailed calculation process of Step 3, Step 4 and Step 5, the position and interval angle of each multi-color LED unit in the circumferential direction can be accurately determined, which helps to achieve uniform distribution of LED units in the circumferential direction, thereby improving the consistency and aesthetics of display effect. Accurate LED unit layout helps to optimize the display effect of multi-color LED, ensures uniform color mixing, reduces color deviation and visual discomfort. Through the clear mathematical formula and calculation steps, the efficient and accurate calculation method is used to determine the arrangement of LED units, which not only simplifies the design process, but also improves the production efficiency. Since this embodiment is based on mathematical calculation to determine the arrangement of LED units, it can easily adapt to LED arrays of different sizes and shapes. In addition, by adjusting the calculation parameters, it can also be easily extended to more complex multi-layer annular arrangement design. Accurate arrangement calculation helps to achieve consistency in product quality, reduces the rate of defective products caused by uneven arrangement, and improves production efficiency.

[0059] Optionally, the number of multi-color LEDs is determined according to the interval length and the circumference in the circumferential direction, specifically including: obtaining the quotient of the circumference and the interval length; and rounding the quotient of the circumference and the interval length, and determining the value obtained after rounding as the number of multi-color LEDs.

[0060] Specifically, the number N of multi-color LED units i =Int(C i / δL i ), wherein Int() is a rounding operation.

[0061] By calculating the quotient of the circumference and the interval length, and performing an integer operation (which can be rounded up or rounded down), the number of multi-color LEDs can be accurately determined, avoiding errors caused by human judgment or estimation, and ensuring the accuracy of the number of LEDs. The number of LEDs calculated accurately can maximize the use of available arrangement space, avoiding the installation of too many or too few LED units, thereby optimizing resource utilization and reducing costs. Reasonable LED number and arrangement are the basis to ensure display effect. By accurately calculating the number of LEDs, it can be ensured that the display effect meets the expectations, and the poor display effect caused by improper LED number is avoided.

[0062] 400: Determine the new area of the multi-color LED unit according to the interval angle.

[0063] Specifically, the steps of this embodiment can be completed by Step6-Step7.

[0064] Optionally, determining the new area of the multi-color LED unit according to the interval angle, specifically includes: determining the new interval length of the multi-color LED unit in the circumferential direction according to the radius and the interval angle; determining the new area of the multi-color LED unit according to the radial increment and the new interval length.

[0065] Specifically, Step6: Calculate the new interval length δL of the multi-color LED unit in the circumferential direction Li_New .

[0066] Step7: Calculate the new area S of the multi-color LED unit i_new .

[0067] By accurately calculating and adjusting the area of the LED unit, the distribution and intensity of light can be more effectively controlled, thereby optimizing the overall display effect. According to the interval angle, the area of the LED unit is dynamically adjusted, which can more effectively utilize the available display space, helping to reduce space waste while ensuring the optimization of display effect.

[0068] Optionally, determining the new interval length of the multi-color LED unit in the circumferential direction according to the radius and the interval angle, specifically includes: obtaining the sine value of half of the interval angle; obtaining the product of the sine value and the radius; doubling the product as the new interval length of the multi-color LED unit in the circumferential direction.

[0069] Specifically, the new interval length δL of the multi-color LED unit in the circumferential direction i_New = 2 * r i *sin(δθ i / 2).

[0070] The method is more accurate than the traditional estimation or experience judgment, and ensures that the interval between the LED units is scientifically calculated rather than randomly set, thereby improving the accuracy of the entire LED layout. The new interval length between the LED units is dynamically determined according to the radius and the interval angle, which can make the layout of the LED more reasonable and efficient.

[0071] 500: determining whether the new area belongs to the accuracy range; if the new area belongs to the accuracy range, outputting the radius and the interval angle; if the new area does not belong to the accuracy range, updating the radial increment of the current arrangement array, and continuing to calculate the new area of the multi-color LED unit according to the updated radial increment until the new area belongs to the accuracy range.

[0072] Specifically, the steps of the embodiment can be completed by Step 8-Step 9.

[0073] Step 8: determining whether Si_new∈[S1, S2] range.

[0074] Step 9: if the requirement of Step 8 is met, outputting r i and δθ i , reassigning i to i+1 (i=i+1), and entering the calculation of the next round of arrangement array; otherwise, redefining δr=δr±Δr; and repeating step 2-step 8.

[0075] By continuously iterating the calculation and adjusting the radial increment, it can be ensured that the new area of the multi-color LED unit falls within the predetermined accuracy range. When the newly calculated LED unit area is not within the accuracy range, the system will automatically update the radial increment and recalculate until the accuracy requirement is met. This adaptive adjustment capability enables the embodiment to flexibly respond to different design requirements and limitations. Through repeated calculation and adjustment, the embodiment can find the optimal arrangement array parameters (radius and interval angle), thereby ensuring that the layout of the LED units is compact and efficient, and fully utilizing the available display space. By accurately calculating and strictly controlling the area of the LED unit within the accuracy range, it is helpful to produce LED products with more stable quality and better display effect.

[0076] Optionally, if the new area does not belong to the accuracy range, updating the radial increment of the current arrangement array, specifically including: if the new area does not belong to the accuracy range and is less than the left endpoint of the accuracy range, increasing the radial increment by a fixed value; if the new area does not belong to the accuracy range and is greater than the right endpoint of the accuracy range, decreasing the radial increment by a fixed value.

[0077] Specifically, if S i_newIf S2, then dr = dr - Ar; and repeat step 2-step 8; if S1, then dr = dr + Ar; and repeat step 2-step 8. i_new If S2, then dr = dr - Ar; and repeat step 2-step 8; if S1, then dr = dr + Ar; and repeat step 2-step 8.

[0078] By increasing or decreasing the radial increment, the area of the LED unit is accurately adjusted to gradually approach and finally fall within the accuracy range, which ensures the accuracy of the LED unit area and the uniformity and quality of the display effect. This embodiment considers two cases where the new area is less than the left endpoint of the accuracy range and greater than the right endpoint of the accuracy range, and respectively gives the corresponding adjustment strategies, enhancing flexibility and applicability.

[0079] As shown in Figure 3 is a lensless multi-color LED arrangement diagram. The LED can use SDL lamp beads, Figure 3 with a circular lamp of diameter Φ = 1.5m as an example, S = 160mm 2 , and its accuracy ΔS ∈ ±0.001mm 2 , r0 ∈ [10, 30], the LED distribution as shown in Figure 3 is obtained by the above calculation method. Based on the LED distribution as shown in Figure 3 , the lensless multi-color LED simulation brightness diagram as shown in Figure 4 can be obtained.

[0080] As shown in Figure 5 is a lens multi-color LED arrangement diagram, including SDL lamp beads + lens arrangement: with a circular lamp of diameter Φ = 600mm as an example, S = 300mm 2 , and its accuracy ΔS ∈ ±0.005mm 2 , r0 = 35mm, the LED distribution as shown in Figure 5 is obtained by the above calculation method. Based on the LED distribution as shown in Figure 5 , the lens multi-color LED simulation brightness diagram as shown in Figure 6 can be obtained.

[0081] Through the above algorithm, a series of r i and corresponding δθ iAccording to the calculation of each parameter, the multi-color LED optimal arrangement of the whole lamp can be obtained through the arrangement of each array. The calculation method can quickly realize the high uniformity arrangement of multi-color LEDs (three colors, four colors or more colors). The calculation method can also realize the high uniformity arrangement of multi-color LEDs locally, for example, in order to meet the process requirements, a large-size area light source needs to be divided into N small sizes, and the calculation method can also meet the high uniformity requirement in each small size. The calculation method is not only suitable for the arrangement of multi-color LEDs, but also suitable for the arrangement of multi-color LEDs+lens. In summary, the embodiment can be used for SDL lamps or display backlight, such as SDL ceiling lamp, SDL lamp panel, SDL sky screen and display backlight, etc.
