[0002] With the advancement of technology and people's increasing pursuit of quality of life, LED lighting technology has become the mainstream in the modern lighting field. Especially in multi-color LED lighting systems, their advantages such as rich colors, energy saving, environmental friendliness, and long lifespan are widely welcomed by the market. However, while achieving colorful lighting effects, ensuring the uniformity of single-color and multi-color mixing has become a significant technical challenge. The arrangement design of multi-color LEDs not only affects the aesthetics of the luminaire but also directly relates to the quality of the lighting effect and the user experience.

[0003] Currently, the layout design of multi-color LEDs typically employs traditional grid layouts or arrangements based on specific geometric patterns. While these methods are simple and easy to implement, they often fall short when faced with complex and ever-changing lighting needs and stringent uniformity requirements.

[0037] To make the objectives, technical solutions, and advantages of this embodiment clearer, the technical solutions of this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, not all embodiments. Based on the embodiments of this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this embodiment.

[0038] Software-defined lighting (SDL) LEDs are currently used in surface light sources due to their high CRI and wide color gamut. This embodiment addresses the issue of multi-color LEDs needing to meet both the uniformity requirements of a single monochromatic light and the uniformity requirements of multi-color mixing, while also requiring matching power supply requirements. The large number of LEDs makes their arrangement difficult, resulting in long arrangement cycles, low uniformity, and a lengthy design cycle, making it challenging to simultaneously meet both monochromatic and multi-color requirements.

[0039] To address the aforementioned issues, this embodiment provides a method, apparatus, and device for arranging multi-color LED units, which solves the problems of difficulty in simultaneously meeting the requirements of multi-color and single-color uniformity, large number of LED beads, long arrangement design cycle, and low efficiency.

[0040] The following is combined with Figures 1 to 8 The implementation scheme of this embodiment is described.

[0041] Figure 1 The diagram shown is a flowchart of the multi-color LED unit arrangement method provided in this embodiment, which may include the following steps:

[0042] 100: Initialize the area of ​​the multi-color LED unit and determine the accuracy range of the multi-color LED unit area.

[0043] Specifically, such as Figure 2 The diagram shown is a flowchart of the further multi-color LED unit arrangement method provided in this embodiment, including Step 1-Step 8. Step 1-Step 8 will be described in detail below.

[0044] The steps in this embodiment can be completed through Step 1.

[0045] Step 1: Select a suitable area unit S and determine its accuracy range [S1, S2].

[0046] By determining the appropriate area unit occupied by a single LED unit (such as an LED bead), it can be ensured that the arrangement of LED units satisfies both monochrome uniformity and multicolor uniformity. Simultaneously, determining the range of area units ensures the accuracy and consistency of the LED arrangement. By setting the area unit S occupied by the LED bead and its accuracy range, it is possible to adapt to the LED arrangement requirements of different sizes and precisions, improving the flexibility and applicability of the design.

[0047] 200: Obtain the radial increment of the current array and determine the radius of the current array based on the radial increment.

[0048] Specifically, the steps in this embodiment can be completed through Step 2.

[0049] Step 2: Take the radial increment δr of the array and calculate its radius r. i , where r i =r i-1 +δr.

[0050] Taking a round lamp as an example, its arrangement is a series of concentric circles of LED beads, starting from the inner circle and gradually expanding outwards. The radial increment δr represents the increase in radius between the current and previous circles, and i represents the arrangement order of the current array on the round lamp from the inner to the outer circle.

[0051] By taking the radial increment δr, and updating the radius r accordingly. i (r i =r i-1 The +δr method enables precise control over the radial position of the LED arrangement. This is the foundation for constructing circular or annular LED arrangements, ensuring that the radial position of each LED unit is determined by a specific increment. The value of δr can be adjusted according to specific needs, thereby changing the radial spacing between LED units. This flexibility allows the design to adapt to LED arrangements of different sizes and densities. A uniform radial increment δr ensures a uniform distribution of LED units in the radial direction, contributing to improved overall aesthetics and consistent display performance. This incremental approach simplifies computational resource consumption, making the algorithm more efficient and easier to implement. It also facilitates subsequent steps for calculating circumferential spacing lengths, the number of LED units, etc.

[0052] 300: The circumferential spacing angle of the multicolor LED unit is determined based on the radial increment and radius.

[0053] Specifically, the steps in this embodiment can be completed through Steps 3-5.

[0054] Optionally, the circumferential spacing angle of the multicolor LED units is determined based on the radial increment and the radius, specifically including: determining the circumferential spacing length of the multicolor LED units based on the radial increment, determining the perimeter of the current array based on the radius; determining the number of multicolor LEDs based on the circumferential spacing length and the perimeter; and determining the circumferential spacing angle of the multicolor LED units based on the number of multicolor LEDs.

[0055] Specifically, Step 3: Calculate the circumferential spacing length δL of the multi-color LED units. i and its perimeter C i Among them, the circumferential interval length δL i =S / δr, circumference C i =2*π*r i .

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

[0057] Step 5: Calculate the circumferential spacing angle δθ of the multi-color LED units. i Wherein, the interval angle δθ i =2*π / N i .

[0058] Through detailed calculations in Steps 3, 4, and 5, the circumferential position and spacing angle of each multi-color LED unit can be precisely determined, facilitating a uniform circumferential distribution of LED units and improving the consistency and aesthetics of the display. Precise LED unit layout helps optimize the display effect of multi-color LEDs, ensuring uniform color mixing and reducing color deviation and visual discomfort. The efficient and accurate calculation method, using clear mathematical formulas and calculation steps, simplifies the design process and improves production efficiency. Since this embodiment uses mathematical calculations to determine the LED unit arrangement, it can easily adapt to LED arrays of different sizes and shapes. Furthermore, by adjusting the calculation parameters, it can be easily extended to more complex multi-layer ring-shaped arrangements. Precise layout calculations help achieve consistent product quality, reduce the defect rate caused by uneven layout, and thus improve production efficiency.

[0059] Optionally, the number of multi-color LEDs can be determined based on the circumferential interval length and the perimeter, specifically including: obtaining the quotient of the perimeter and the interval length; rounding the quotient of the perimeter and the interval length, and determining the rounded value as the number of multi-color LEDs.

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

[0061] By calculating the quotient of the perimeter and the interval length, and then rounding it down (either up or 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 LED count. The precisely calculated number of LEDs maximizes the use of available layout space, avoiding installing too many or too few LED units, thereby optimizing resource utilization and reducing costs. A reasonable number and arrangement of LEDs is fundamental to ensuring display quality. Accurately calculating the LED count ensures that the display effect meets expectations and avoids poor display results due to an inappropriate number of LEDs.

[0062] 400: Determine the new area of ​​the multicolor LED unit based on the spacing angle.

[0063] Specifically, the steps in this embodiment can be completed through Step 6-Step 7.

[0064] Optionally, the new area of ​​the multicolor LED unit is determined based on the spacing angle, specifically including: determining the new circumferential spacing length of the multicolor LED unit based on the radius and the spacing angle; and determining the new area of ​​the multicolor LED unit based on the radial increment and the new spacing length.

[0065] Specifically, Step 6: Calculate the new circumferential spacing length δ of the multicolor LED units. Li_New .

[0066] Step 7: Calculate the new area unit S of the multi-color LED unit. i_new .

[0067] By precisely calculating and adjusting the area of ​​the LED units, the distribution and intensity of light can be controlled more effectively, thereby optimizing the overall display effect. Dynamically adjusting the area of ​​the LED units according to the spacing angle allows for more efficient use of available display space, helping to reduce space waste while ensuring optimal display performance.

[0068] Optionally, a new circumferential spacing length of the multicolor LED unit is determined based on the radius and the spacing angle, specifically including: obtaining the sine value of half the spacing angle; obtaining the product of the sine value and the radius; and using twice the product as the new circumferential spacing length of the multicolor LED unit.

[0069] Specifically, the new circumferential spacing length δL of the multicolor LED units i_New =2*r i *sin(δθ i / 2).

[0070] By using mathematical formulas (i.e., the sine function) to calculate the new circumferential spacing length of multi-color LED units, this method is more accurate than traditional estimation or empirical judgment. It ensures that the spacing between LED units is scientifically calculated rather than arbitrarily set, thereby improving the accuracy of the overall LED layout. Dynamically determining the new spacing length between LED units based on the radius and spacing angle allows for a more rational and efficient LED layout.

[0071] 500: Determine if the new area is within the accuracy range; if the new area is within the accuracy range, output the radius and spacing angle; if the new area is not within the accuracy range, update the radial increment of the current array, and continue to calculate the new area of ​​the multi-color LED unit based on the updated radial increment until the new area is within the accuracy range.

[0072] Specifically, the steps in this embodiment can be completed through Step 8-Step 9.

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

[0074] Step 9: If the requirements of Step 8 are met, output r. i and δθ i Then, reassign i to i+1 (i=i+1) and proceed to the next round of array calculation; otherwise, redefine δr=δr±Δr; and repeat steps 2 to 8.

[0075] By iteratively calculating and adjusting the radial increment, the system ensures that the new area of ​​the multi-color LED units falls within a predetermined accuracy range. When the newly calculated LED unit area is outside this range, the system automatically updates the radial increment and recalculates until the accuracy requirements are met. This adaptive adjustment capability allows this embodiment to flexibly address different design needs and constraints. Through repeated calculations and adjustments, this embodiment finds the optimal array parameters (radius and spacing angle), ensuring that the LED unit layout is both compact and efficient, making full use of available display space. Precise calculation and strict control of the LED unit area within the accuracy range contribute to the production of LED products with more stable quality and superior display effects.

[0076] Optionally, if the new area is not within the accuracy range, the radial increment of the current arrangement array is updated, specifically: if the new area is not within the accuracy range and is less than the left endpoint of the accuracy range, the radial increment is increased by a fixed value; if the new area is not within the accuracy range and is greater than the right endpoint of the accuracy range, the radial increment is decreased by a fixed value.

[0077] Specifically, if S i_newIf S > S2, then δr = δr - Δr; and repeat steps 2 to 8; if S i_new If <S1, then δr=δr+Δr; and repeat steps2~step8.

[0078] By precisely adjusting the area of ​​the LED unit by increasing or decreasing the radial increment, gradually bringing it closer to and ultimately within the accuracy range, this adjustment method ensures the accuracy of the LED unit area, thereby guaranteeing the uniformity and quality of the display effect. This embodiment considers two cases: the new area is smaller than the left endpoint of the accuracy range and larger than the right endpoint of the accuracy range, and provides corresponding adjustment strategies for each, enhancing flexibility and applicability.

[0079] like Figure 3 The diagram shows a lensless multi-color LED layout. This LED can use SDL chips. Figure 3 The example shown is a round lamp with a diameter of Φ = 1.5m, with S = 160mm. 2 And its accuracy ΔS∈±0.001mm 2 r0∈[10, 30], obtained through the above calculation method as follows Figure 3 The LED distribution is shown. Based on... Figure 3 The LED distribution shown can lead to the following: Figure 4 The image shows a simulated brightness diagram of a lensless multicolor LED.

[0080] like Figure 5 The diagram shows the arrangement of multi-color LEDs with lenses, including SDL LEDs and lens arrangement: taking a round lamp with a diameter of Φ = 600mm as an example, and taking S = 300mm. 2 And its accuracy ΔS∈±0.005mm 2 r0 = 35mm, obtained through the above calculation method as follows Figure 5 The LED distribution is shown. Based on... Figure 5 The LED distribution shown can lead to the following: Figure 6 The image shown is a simulated brightness diagram of a multi-color LED with a lens.

[0081] Using the above algorithm, a series of r values ​​for multi-color LEDs can be obtained. i and the corresponding δθ iBased on the calculation of its various parameters, the optimized arrangement of multi-color LEDs for the entire lamp can be obtained through the arrangement of each array. This calculation method can quickly achieve a highly uniform arrangement of multi-color LEDs (three-color, four-color, or more colors). This calculation method can also achieve a highly uniform arrangement of multi-color LEDs locally. For example, to meet process requirements, a large-size surface light source needs to be divided into N smaller sizes. Applying this calculation method to each smaller size can also meet the high uniformity requirements. This calculation method is not only applicable to the arrangement of multi-color LEDs but also suitable for the arrangement of multi-color LEDs + lenses. In summary, this embodiment can be used for SDL lighting fixtures or display backlights, such as SDL ceiling lights, SDL light panels, SDL canopies, and their display backlights.
