[0033] Referring to Figure 1 An embodiment of the present application provides an LED light source 100, which comprises a light source plate 10 and a light emitting unit 20 arranged on the light source plate 10.

[0034] Specifically, a longitudinal axis 101 passing through the center of the light source plate 10 is formed on the surface of the light source plate 10. The light emitting unit 20 is provided in plurality, and the plurality of light emitting units 20 are arranged in a multi-row and multi-column array on the surface of the light source plate 10, and the light emitting units 20 in adjacent two rows are arranged staggeredly.

In other examples, the number and type of light elements in the light emitting unit 20 can be changed according to the actual light emitting needs of the product, which is not limited here.

[0036] Among them, the plurality of light emitting units 20 include a first unit 21 (shown as "①" in the drawings), a second unit 22 (shown as "②" in the drawings), a third unit 23 (shown as "③" in the drawings) and a fourth unit 24 (shown as "④" in the drawings).

[0037] As Figure 2 shown, the first row of the first unit 21 is in turn a red light light element 201, an auxiliary light light element 204 and a green light light element 202, and the second row of the first unit 21 is in turn an auxiliary light light element 204, a red light light element 201 and a blue light light element 203. As Figure 3 shown, the first row of the second unit 22 is in turn a red light light element 201, an auxiliary light light element 204 and a blue light light element 203, and the second row of the second unit 22 is in turn an auxiliary light light element 204, a red light light element 201 and a green light light element 202. As Figure 4As shown, the first row in the third unit 23 is in turn the auxiliary light light element 204, the red light light element 201 and the blue light light element 203, and the second row in the third unit 23 is in turn the red light light element 201, the auxiliary light light element 204 and the green light light element 202. As shown, Figure 5 As shown, the first row in the fourth unit 24 is in turn the auxiliary light light element 204, the red light light element 201 and the green light light element 202, and the second row in the fourth unit 24 is in turn the red light light element 201, the auxiliary light light element 204 and the blue light light element 203.

[0038] The multiple rows of light emitting units 20 on the light source board 10 include a plurality of first light emitting row groups 20a and a plurality of second light emitting row groups 20b, the first light emitting row groups 20a and the second light emitting row groups 20b are arranged alternately on the light source board 10. The first light emitting row groups 20a include a plurality of first units 21 and a plurality of second units 22, the first units 21 and the second units 22 are arranged alternately. The second light emitting row groups 20b include a plurality of third units 23 distributed on both sides of the longitudinal axis 101 and a plurality of fourth units 24 distributed on both sides of the longitudinal axis 101, the light emitting units in the second light emitting row groups 20b on both sides of the longitudinal axis 101 are arranged symmetrically about the longitudinal axis 101, and the third units 23 and the fourth units 24 on both sides of the longitudinal axis 101 are arranged alternately.

[0039] For the LED light source 100 of this application, in each light-emitting unit 20, six light elements are arranged in two rows and three columns, with light elements of different colors spaced apart. The light emitted by the six light elements can begin to mix at close range. Because the distance between the light elements in each light-emitting unit 20 is relatively short, the light can be fully superimposed and mixed, making the light emitted from a single light-emitting unit 20 more uniform in color. Each light-emitting unit 20 includes red, green, and blue primary color light elements and two auxiliary light elements 204, arranged in an orderly manner. This configuration can achieve precise color matching through the accurate mixing of different colors of light, which can meet the needs of professional lighting scenarios with extremely high requirements for color accuracy. The adjacent rows of light-emitting units 20 are staggered, and the arrangement of the light elements in different light-emitting units 20 is also different, making the light emitted by different colors more uniform in color. The light can be better mixed during propagation, making the light emitted by the light-emitting units 20 on the entire light source board 10 more uniform and natural in color, avoiding color patches or unevenness. This provides a better visual experience in large-area lighting or display applications. In addition, the first light-emitting row group 20a and the second light-emitting row group 20b are arranged alternately, and the first unit 21, the second unit 22, the third unit 23 and the fourth unit 24 are arranged alternately in their respective row groups. This complex alternating arrangement further enhances the light mixing effect. The light emitted by different types of light-emitting units 20 can be mixed and coordinated on a larger scale, making the light emitted by the entire light source board 10 more stable and uniform in optical performance. This provides highly uniform light in large-area lighting or display scenarios, efficiently meeting the light emission requirements of photography and video lighting.

[0040] In some embodiments of this application, the light source board 10 is used to support and mount the light-emitting unit 20, and can provide electrical connection and physical support for the light-emitting unit 20 to realize the electrical connection and fixed assembly of the light-emitting unit 20, thereby realizing the light-emitting function of the LED light source 100.

[0041] The surface of the light source plate 10, on which the light-emitting units 20 are mounted, has a longitudinal axis 101 passing through the center of the light source plate 10. The extending direction of the longitudinal axis 101 is consistent with the extending direction of the entire row of light-emitting units 20. In some examples, the light source plate 10 is circular, and the longitudinal axis 101 passes through the center of the light source plate 10. In other examples, the light source plate 10 can also be set into a square, polygonal, irregular shape, etc., according to the design requirements of the actual product.

[0042] In this example, the surface of the light source plate 10 used to mount the light-emitting unit 20 is also formed with a transverse axis 102 passing through the center of the light source plate 10. The extension direction of the transverse axis 102 is consistent with the extension direction of the entire row of light-emitting units 20, and perpendicular to the extension direction of the longitudinal axis 101.

[0043] Further, the plurality of light emitting units 20 are arranged in a multi-row and multi-column array on the surface of the light source plate 10.

[0044] Each light emitting unit 20 includes six light elements, and the six light elements are two red light elements 201, two auxiliary light elements 204, one green light element 202, and one blue light element 203 arranged in two rows and three columns. The length direction of the light emitting unit 20 is perpendicular to the extension direction of the longitudinal axis 101.

[0045] The red light element 201 can emit red light when powered on, the green light element 202 can emit green light when powered on, and the blue light element 203 can emit blue light when powered on.

[0046] Specifically, the red light element 201 can be composed of a red light chip, which can directly emit red light by being powered on. Alternatively, the red light element 201 can be composed of a non-red light chip combined with phosphor powder, and the light emitted by the non-red light chip can emit red light after being excited by the phosphor powder. Similarly, the green light element 202 and the blue light element 203 can also be designed according to the same principle.

[0047] The red light element 201 can emit light in a wavelength range of 615 nm to 660 nm, the green light element 202 can emit light in a wavelength range of 515 nm to 540 nm, and the blue light element 203 can emit light in a wavelength range of 420 nm to 485 nm.

[0048] In some examples, the auxiliary light element 204 can be a cool white light element or a warm white light element. The warm white light element emits light with a warm color tone, and the color temperature is generally below 3000 K. The cool white light element emits light with a cool color tone, and the color temperature is generally above 5000 K.

[0049] The cool light element and the warm light element can each include an LED chip and phosphor powder. The LED chip can be a blue light LED chip, an ultraviolet LED chip, etc., and the phosphor powder can be yellow phosphor powder, red, green, and blue three-color phosphor powder. Specifically, the light emitted by the LED chip can excite the phosphor powder to produce warm white light or cool white light.

[0050] When the cool white light element and / or the warm white light element are combined with the red, green, and blue light elements 203, more rich color levels and color tone choices can be provided in different scenes. For example, in a display scene requiring high color reproduction, the cool white light auxiliary light can enhance the contrast and clarity of the color of the object, making the red color more vibrant, the green color more emerald green, and the blue color more pure. The warm white light auxiliary light can make the overall color tone more biased towards the warm color tone, which is suitable for creating a comfortable environmental atmosphere.

[0051] And, the auxiliary light element 204 can also adjust the overall color output when matched with the red, green and blue light elements 203, so that the mixed light is more uniform and natural in color, which helps to achieve the balance and coordination of the overall color, so that the light of the entire light emitting unit 20 and the light source plate 10 is more uniform.

[0052] In addition, the cold white light element or the warm white light element itself has a certain luminous intensity, which can increase the overall illumination intensity as an auxiliary light element 204, so that the light emitting unit 20 can provide brighter light and improve the overall brightness of the LED light source 100.

[0053] In this example, each light emitting unit 20 includes six packaging shells, and the six light elements are correspondingly packaged through the six packaging shells. That is, in each light emitting unit 20, the six light elements each have an independent packaging shell.

[0054] The LED light source 100 of this example can be manufactured by independently installing the red light element 201, the green light element 202, the blue light element 203 and the auxiliary light element 204 on the light source plate 10 according to the corresponding arrangement. This structure not only facilitates the replacement and maintenance of different light elements, but also facilitates the cutting of the light emitting unit 20 at the edge corresponding to the shape of the light source plate 10, thereby ensuring the stability of the overall structure of the LED light source 100.

[0055] In this application, the two red light elements 201, the two auxiliary light elements 204, the green light element 202 and the blue light element 203 in each light emitting unit 20 are arranged in two rows and three columns, and the light elements of different colors are spaced apart from each other.

[0056] When these light elements emit light at the same time, the light emitted by them begins to mix at close range. Since the distance between the light elements is relatively short, the light can be fully superimposed and mixed, so that the light emitted from a single light emitting unit 20 is more uniform in color, avoiding the phenomenon of color separation or uneven color when observed at close range.

[0057] And, the two adjacent rows of light emitting units 20 on the light source plate 10 are arranged staggered. This arrangement allows the light emitted by different light emitting units 20 to interweave and mix better during propagation. Compared with the neatly arranged light emitting units 20, the staggered arrangement of the present application increases the path and angle of light mixing, so that the light can be more fully mixed in space, thereby achieving uniform distribution of light color in a larger range. Whether viewed from the front or at an angle, the light source plate 10 can be seen to have uniform and consistent color, without local color being too thick or too thin.

[0058] Further, in the present application, in combination with Figures 2 to 5 As shown in FIG. 1, the plurality of light emitting units 20 include a first unit 21, a second unit 22, a third unit 23, and a fourth unit 24.

[0059] For the first unit 21 and the second unit 22, the arrangement of the red light elements 201 and the auxiliary light elements 204 in the first unit 21 is the same as that in the second unit 22. Specifically, in the first unit 21 and the second unit 22, the two red light elements 201 and the two auxiliary light elements 204 form a square structure, and the red light elements 201 and the auxiliary light elements 204 are arranged diagonally.

[0060] In the first unit 21 and the second unit 22, the arrangement of the blue light elements 203 and the green light elements 202 is different. Specifically, in the first unit 21, the blue light elements 203 are arranged at the positions of the second row and the third column in the light emitting unit 20, and the green light elements 202 are arranged at the positions of the first row and the third column in the light emitting unit 20. In the second unit 22, the blue light elements 203 are arranged at the positions of the first row and the third column in the light emitting unit 20, and the green light elements 202 are arranged at the positions of the second row and the third column in the light emitting unit 20.

[0061] For the third unit 23 and the fourth unit 24, the arrangement of the red light elements 201 and the auxiliary light elements 204 in the third unit 23 is the same as that in the fourth unit 24, and is opposite to that in the first unit 21 and the second unit 22.

[0062] Specifically, in the first unit 21 and the second unit 22, the two red light elements 201 and the two auxiliary light elements 204 form a square structure, and the red light elements 201 and the auxiliary light elements 204 are arranged diagonally.

[0063] In the third unit 23 and the fourth unit 24, the arrangement of the blue light elements 203 and the green light elements 202 is different. Specifically, in the third unit 23, the blue light elements 203 are arranged at the positions of the first row and the third column in the light emitting unit 20, and the green light elements 202 are arranged at the positions of the second row and the third column in the light emitting unit 20. In the fourth unit 24, the blue light elements 203 are arranged at the positions of the second row and the third column in the light emitting unit 20, and the green light elements 202 are arranged at the positions of the first row and the third column in the light emitting unit 20.

[0064] In the present application, the arrangement of light elements in the first unit 21, the second unit 22, the third unit 23 and the fourth unit 24 is different, so that the mixed light mode of the light emitted by each unit during propagation is different, so that the light emitted by them produces a unique effect when mixed. Through this diversified light mixing, the light finally presented can be more soft and natural, reducing color deviation and light spot phenomenon in the light, and improving the uniformity of light mixing.

[0065] Furthermore, the arrangement of the first unit 21, the second unit 22, the third unit 23 and the fourth unit 24 on the light source plate 10 makes the distribution of light elements of different colors more uniform on the entire light source plate 10. When emitting light, the light of each unit is complementary and fused, reducing the spatial non-uniformity of color, avoiding the situation that the local color is too deep or too shallow, making the overall lighting effect more uniform and consistent, and improving the user's visual comfort.

[0066] Further, in the present application, the plurality of light emitting units 20 on the light source plate 10 include a plurality of first light emitting row groups 20a and a plurality of second light emitting row groups 20b, and the first light emitting row groups 20a and the second light emitting row groups 20b are arranged alternately on the light source plate 10.

[0067] Among them, the first light emitting row group 20a includes a plurality of first units 21 and a plurality of second units 22, and the first units 21 and the second units 22 are arranged alternately. The second light emitting row group 20b includes a plurality of third units 23 distributed on both sides of the longitudinal axis 101 and a plurality of fourth units 24 distributed on both sides of the longitudinal axis 101, and the light emitting units in the second light emitting row group 20b on both sides of the longitudinal axis 101 are symmetrically arranged about the longitudinal axis 101, and the third units 23 and the fourth units 24 on both sides of the longitudinal axis 101 are alternately arranged.

[0068] The first light emitting row group 20a and the second light emitting row group 20b are arranged alternately, and the first units 21 and the second units 22 in the first light emitting row group 20a are arranged alternately, and the third units 23 and the fourth units 24 arranged on both sides of the longitudinal axis in the second light emitting row group 20b are arranged alternately. This complex alternating arrangement further enhances the light mixing effect, and the light emitted by different types of light emitting units 20 is mixed and cooperated on a larger scale, so that the light emitted by all light emitting units 20 on the entire light source plate 10 is more stable and uniform in optical performance, which can provide highly uniform light in large-area lighting or display scenarios, effectively avoiding visual interference caused by uneven light, and greatly improving the color uniformity of the emitted light.

[0069] In some examples, for all light emitting units 20 in the second light emitting row group 20b, the light emitting units 20 on both sides of the longitudinal axis 101 are symmetrically arranged about the longitudinal axis 101.

[0070] The light emitted by the light emitting units 20 in the second light emitting row group 20b is symmetrically distributed on both sides of the longitudinal axis 101, which presents high symmetry, effectively avoids the situation that the light is too concentrated on one side and too dark on the other side, and ensures that the light distribution in the entire light emitting area is more uniform. Moreover, the light emitting units 20 at the symmetric positions with respect to the longitudinal axis 101 in the second light emitting row group 20b are the same, and the red, green, blue, cold white light, warm white light and other light emitted by the light emitting units 20 can be mixed in a symmetrical manner on both sides of the longitudinal axis 101, further improving the uniformity of the mixed light.

[0071] In some embodiments of the present application, in combination with Figure 6 and Figure 7 As shown in the figures, in all the first light emitting row groups 20a on the light source board 10, all the first units 21 are arranged in longitudinal alignment in the extension direction of the longitudinal axis 101, and all the second units 22 are arranged in longitudinal alignment in the extension direction of the longitudinal axis 101.

[0072] In this arrangement structure, the first units 21 and the second units 22 are respectively arranged in longitudinal alignment, so that the light propagation of the light elements inside each unit in the longitudinal direction is more orderly, and the light emitted by the light elements of different colors in the same light emitting unit 20 can be better superimposed and fused in the longitudinal direction, reducing the light intensity fluctuation in the longitudinal direction inside the light emitting unit 20, which helps to form a more uniform light distribution.

[0073] Moreover, all the first units 21 and all the second units 22 on the light source board 10 are respectively arranged in longitudinal alignment, which can form a regular light emitting structure in the longitudinal direction for the first light emitting row group 20a. In this way, in the extension direction of the longitudinal axis 101, the transition of the light is smoother and more coherent from one first unit 21 to the adjacent second unit 22, and then to the first unit 21 and the second unit 22 of the next group, further improving the light uniformity in the longitudinal direction of the entire first light emitting row group 20a.

[0074] Further, in all the second light emitting row groups 20b on the light source board 10, all the third units 23 are arranged in longitudinal alignment in the extension direction of the longitudinal axis 101, and all the fourth units 24 are arranged in longitudinal alignment in the extension direction of the longitudinal axis 101.

[0075] In this arrangement structure, the third units 23 and the fourth units 24 are respectively arranged in longitudinal alignment, so that the light propagation of the light elements inside each unit in the longitudinal direction is more orderly, and the light emitted by the light elements of different colors in the same light emitting unit 20 can be better superimposed and fused in the longitudinal direction, reducing the light intensity fluctuation in the longitudinal direction inside the light emitting unit 20, which helps to form a more uniform light distribution.

[0076] And, all the third units 23 and all the fourth units 24 on the light source plate 10 are respectively longitudinally aligned, which can make the first light emitting row group 20a form a regular light emitting structure in the longitudinal direction. In this way, in the extension direction of the longitudinal axis 101, from one third unit 23 to the adjacent fourth unit 24, and then to the third unit 23 and the fourth unit 24 of the next group, the transition of the light is smoother and more coherent, further improving the light uniformity of the entire second light emitting row group 20b in the longitudinal direction.

[0077] In addition, the first units 21 and the second units 22 in the first light emitting row group 20a are longitudinally aligned, combined with the longitudinal alignment of the third units 23 and the fourth units 24 in the second light emitting row group 20b, on the one hand, it can make the light distribution inside each row group more uniform, and the light emitted by the light elements of different colors in each unit can be better superimposed and fused in the longitudinal direction, so that the mixed light is more uniform and consistent in color and spectral distribution, improving the uniformity of mixed light; on the other hand, it can make the light emitted by the light elements in different units mixed at a relatively fixed angle and path during propagation, whether in a single row group or between row groups, the light can maintain a relatively uniform distribution in the longitudinal and transverse directions, so that the entire light source plate 10 can achieve better light uniformity on a large area.

[0078] In some examples, on the light source plate 10, the first unit 21 or the second unit 22 in the first light emitting row group 20a is arranged on the longitudinal axis 101.

[0079] This arrangement can make the first unit 21 or the second unit 22 in the first light emitting row group 20a located on the longitudinal axis 101 serve as the central reference for light mixing, and accurately superimpose and mix the light emitted by the light emitting units 20 symmetrically arranged in the second light emitting row group 20b, improving the uniformity of mixed light; and the first unit 21 or the second unit 22 in the first light emitting row group 20a located on the longitudinal axis 101, in cooperation with the light emitting units 20 in the second light emitting row group 20b, can expand the area of uniform light distribution, achieve a larger range of uniform illumination or display, and improve the light quality of the entire light emitting area.

[0080] Further, in some embodiments of the present application, the first light emitting row group 20a is arranged on the transverse axis 102, and in the first light emitting row group 20a arranged on the transverse axis 102, the central axis in the width direction of the light emitting unit 20 is arranged in line with the transverse axis 102.

[0081] This arrangement can make the first light emitting row group 20a arranged on the transverse axis 102 be able to more uniformly superimpose and propagate with the second light emitting row groups 20b on both sides in the transverse direction, effectively reducing the light-dark difference in the transverse direction, and forming a relatively uniform illumination area within a certain width range near the center of the light source plate 10.

[0082] In addition, such as Figure 1 As shown, in some embodiments of this application, the LED light source 100 includes four splicable light source structures 110, which are formed by dividing the LED light source 100 along the longitudinal axis 101 and the transverse axis 102.

[0083] The light source structure 110 has a fan-shaped overall outline. Compared to the overall circular light source panel 10, the four interlocking light source structures 110 are smaller and lighter, making them easier to handle during installation. Installers can more easily place each light source structure 110 in its designated position for assembly, reducing installation difficulty and improving efficiency. Furthermore, if the LED light source 100 malfunctions, only the problematic light source structure 110 needs to be repaired or replaced, without replacing the entire circular light source panel 10, significantly reducing maintenance costs and time. In addition, the four interlocking light source structures 110 can be adjusted in angle or direction as needed, allowing for precise adjustment of the light angle and enhancing the user's flexibility in using the LED light source 100.

[0084] For the LED light source of this application, in each light-emitting unit, six light elements are arranged in two rows and three columns, with light elements of different colors spaced apart. The light emitted by the six light elements can begin to mix at close range. Because the distance between the light elements in each light-emitting unit is relatively short, the light can be fully superimposed and mixed, making the light emitted from a single light-emitting unit more uniform in color. Each light-emitting unit contains red, green, and blue primary color light elements and two auxiliary light elements, arranged in an orderly manner. This configuration can achieve precise color matching through the accurate mixing of different colors of light, which can meet the needs of professional lighting scenarios with extremely high requirements for color accuracy. The adjacent rows of light-emitting units are staggered, and the arrangement of light elements in different light-emitting units is also different, so that different colors can be mixed. The different colors of light can be better mixed during propagation, making the light emitted by the light-emitting units on the entire light source board more uniform and natural in color, avoiding color patches or unevenness. This provides a better visual experience in large-area lighting or display applications. In addition, the first and second light-emitting rows are arranged alternately, and the first, second, third, and fourth units are arranged alternately within their respective rows. This complex alternating arrangement further enhances the light mixing effect. The light emitted by different types of light-emitting units can be mixed and coordinated on a larger scale, making the light emitted by the entire light source board more stable and uniform in optical performance. This provides highly uniform light in large-area lighting or display scenarios, efficiently meeting the light emission requirements of photography and video lighting.

As mentioned above, the present application is capable of taking many forms of implementation and being practiced in various ways, and the above description is not intended to limit the application in any way, except as required by the appended claims and their equivalents.
