[0045] In the embodiment, the first light source unit 210 includes four light sources arranged in a rectangular array, and the light source distribution of the first light source unit 210 is relatively regular and symmetrical, which can be beneficial to improve the light emission uniformity and consistency of the first light source unit 210, and further beneficial to improve the light emission uniformity and consistency of the LED light source 10.

[0046] As shown in FIG. 2, the two red light sources 211 in the first light source unit 210 can be arranged side by side. That is, the cool light source 212 and the blue light source 213 in the first light source unit 210 are also arranged side by side. Figure 1

[0047] In the embodiment, the two red light sources 211 in the first light source unit 210 are arranged side by side. However, the present application is not limited thereto, and in other embodiments, the two red light sources 211 in the first light source unit 210 can also be arranged diagonally, which can be determined as appropriate.

[0048] Referring to FIG. 2, in one embodiment, the second light source unit 220 includes warm light sources 221, green light sources 222 and neutral light sources 223, which are distributed in a predetermined manner. Among them, the number and arrangement of the light sources in the second light source unit 220 are the same as those in the first light source unit 210. Figure 1 For example, as shown in FIG. 2, the second light source unit 220 can include one warm light source 221, one green light source 222 and two neutral light sources 223, which are arranged in a rectangular array. Among them, as shown in FIG. 2, the four light sources can be arranged in a 2x2 square matrix.

[0049] As shown in FIG. 2, the four light sources can be arranged in a 2x2 square matrix. Figure 1 As shown in FIG. 2, the four light sources can be arranged in a 2x2 square matrix. Figure 1 As shown in FIG. 2, the four light sources can be arranged in a 2x2 square matrix.

[0050] ​In the embodiment, the second light source unit 220 includes four light sources arranged in a rectangular array. The light sources of the second light source unit 220 are arranged in a relatively regular and symmetrical manner, which can help to improve the uniformity and consistency of the light emission of the second light source unit 220, and further help to improve the uniformity and consistency of the light emission of the LED light source 10.

[0051] As shown in FIG. 2, in an embodiment, the two neutral light sources 223 in the second light source unit 220 are arranged side by side. That is, the one warm light source 221 and the one green light source 222 in the second light source unit 220 are also arranged side by side. Figure 1

[0052] In the embodiment, the two neutral light sources 223 in the second light source unit 220 are arranged side by side. However, the present application is not limited thereto, and in other embodiments, the two neutral light sources 223 in the second light source unit 220 can also be arranged diagonally, which can be determined according to specific requirements.

[0053] In an embodiment not shown in the present application, the first light source unit 210 can include three light sources of different colors. For example, the first light source unit 210 can include one red light source 211, one cool light source 212, and one blue light source 213. Among them, the three light sources can be arranged in a triangular shape. For example, the red light source 211 can be arranged at the upper one of the three ports of the triangle, and the cool light source 212 and the blue light source 213 can be arranged at the lower two ports of the triangle, respectively.

[0054] It can be understood that in other embodiments, the positions of the red light source 211, the cool light source 212, and the blue light source 213 in the first light source unit 210 can also be changed according to specific requirements. For example, in the first light source unit 210, the cool light source 212 can be arranged at the upper one of the three ports, and the red light source 211 and the blue light source 213 can be arranged at the lower two ports, respectively.

[0055] In an embodiment not shown in the present application, the second light source unit 220 can include three light sources of different colors. For example, the second light source unit 220 can include one warm light source 221, one green light source 222, and one neutral light source 223. Among them, the three light sources can be arranged in a triangular shape. For example, the warm light source 221 can be arranged at the upper one of the three ports of the triangle, and the green light source 222 and the neutral light source 223 can be arranged at the lower two ports of the triangle, respectively.

[0056] ​It can be understood that in other embodiments, the three light sources of the second light source unit 220, i.e. the warm light source 221, the green light source 222 and the neutral light source 223, can also be changed in position according to specific requirements. For example, among the three light sources of the second light source unit 220, the neutral light source 223 can be located at the upper one of the ports, and the warm light source 221 and the green light source 222 can be located at the lower two ports.

[0057] It should be noted that in the embodiments of the present application, the first light source unit 210 includes a red light source 211, a cold light source 212 and a blue light source 213, and the second light source unit 220 includes a warm light source 221, a green light source 222 and a neutral light source 223. However, the present application is not limited thereto, and in other embodiments, the three different color light sources included in the first light source unit 210 and the second light source unit 220 can also be changed in light color according to specific requirements. For example, the three different color light sources included in the first light source unit 210 can be a red light source 211, a green light source 222 and a blue light source 213, and the three different color light sources included in the second light source unit 220 can be a warm light source 221, a cold light source 212 and a neutral light source 223.

[0058] Referring to Figure 1 In an embodiment, the LED light source 10 further includes a plurality of supports 230, and all the light sources in each first light source unit 210 are uniformly packaged by a support 230. All the light sources in each second light source unit 220 are uniformly packaged by another support 230. By such an arrangement, the production and assembly of the first light source unit 210, the second light source unit 220 and the LED light source 10 can be more convenient, and the structure is more compact.

[0059] It can be understood that in other embodiments, each different color light source of the first light source unit 210 and the second light source unit 220 can have an independent housing. When manufacturing the LED light source 10 of the present application, the light sources of each color are combined into the first light source unit 210 and the second light source unit 220 as required, and then the first light source unit 210 and the second light source unit 220 are arranged on the light source plate 100 in a predetermined manner. In this way, it is convenient to replace a single damaged light source, and the maintenance convenience of the LED light source 10 is improved.

[0060] Referring to Figure 1 In the present application, the light source plate 100 includes a central light emitting area 110 and a plurality of annular light emitting areas 120. The light source plate 100 can be a circular plate, and the center of the light source plate 100 is the center of the circle. It can be understood that the light source plate 100 can also have other shapes, such as a rectangular shape, an elliptical shape, etc.

[0061] As Figure 1As shown, the central light-emitting area 110 is located at the center of the light source plate 100, and the center of the central light-emitting area 110 coincides with the center of the light source plate 100. The central light-emitting area 110 is provided with a first light source unit 210 and a second light source unit 220, and there are more than one first light source unit 210 and a second light source unit 220. The first light source unit 210 and the second light source unit 220 in the central light-emitting area 110 are distributed in a rectangular array.

[0062] Because one or more first light source units 210 and one or more second light source units 220 are arranged simultaneously in the central light-emitting area 110, the central light-emitting area 110 can simultaneously possess six different colors of light sources. Furthermore, the first light source units 210 and second light source units 220 in the central light-emitting area 110 are distributed in a rectangular array, which makes the distribution of each light source in the central light-emitting area 110 more regular and symmetrical. All the different colors of light sources can complement and superimpose each other, thereby improving the light mixing effect at the center of the light source board 100 and increasing the light emission uniformity of the LED light source 10.

[0063] In one embodiment, in the central light-emitting area 110, the number of first light source units 210 is equal to the number of second light source units 220, and the first light source units 210 and second light source units 220 are arranged alternately in the longitudinal direction and alternately in the transverse direction. By making the number of first light source units 210 in the central light-emitting area 110 equal to the number of second light source units 220, and arranging them alternately, the distribution of light sources of various colors in the central light-emitting area 110 can be made more uniform, ensuring that light sources of various colors can interweave and blend with each other, thereby improving the light mixing effect of the LED light source 10 and improving the light emission uniformity of the LED light source 10.

[0064] For example, such as Figure 3 As shown, in the central light-emitting area 110, there are two first light source units 210 and two second light source units 220, and the two first light source units 210 and the two second light source units 220 are arranged in a rectangular array. That is, the total number of first light source units 210 and second light source units 220 arranged in the central light-emitting area 110 is four, and they are arranged in a square matrix.

[0065] Among them, two first light source units 210 are arranged diagonally, and two second light source units 220 are arranged diagonally. Specifically, as follows... Figure 3 As shown, the two first light source units 210 can be distributed at the lower left and upper right diagonal positions of the square matrix. The two second light source units 220 can be distributed at the upper left and lower right diagonal positions of the square matrix. Thus, the distribution of the two first light source units 210 and the two second light source units 220 within the central light-emitting area 110 is relatively regular and symmetrical, which is beneficial to improving the light emission uniformity of the LED light source 10.

[0066] Referring to Figure 3 In one embodiment, the arrangement angle of the two first light source units 210 is different by a predetermined angle. The predetermined angle can be any angle between 0° and 90°. Preferably, the predetermined angle can be 90°.

[0067] Specifically, as shown in Figure 3 , the first light source unit 210 includes two red light sources 211, one cool light source 212 and one blue light source 213, and the two red light sources 211 are arranged side by side. In this embodiment, the arrangement angle of the first light source unit 210 can refer to the angle between the center line of the two red light sources 211 and the longitudinal direction or the transverse direction when the first light source unit 210 is mounted on the light source board 100.

[0068] In other words, as shown in Figure 3 , of the two first light source units 210, the arrangement angle of one first light source unit 210 is consistent with the longitudinal direction, and the arrangement angle of the other first light source unit 210 is consistent with the transverse direction, i.e. the arrangement angles of the two are different by 90°. When the two first light source units 210 are mounted on the light source board 100, one first light source unit 210 is mounted with the arrangement angle consistent with the longitudinal direction, and the other is mounted by rotating it 90° clockwise or counterclockwise based on it.

[0069] It can be understood that in other embodiments, the arrangement angles of the two first light source units 210 can be different by other angles, such as 45° or 60°, etc.

[0070] Alternatively, in other embodiments, the arrangement angles of the two first light source units 210 can also be consistent. That is, the arrangement angles of the two first light source units 210 can both be consistent with the longitudinal direction, or both be consistent with the transverse direction.

[0071] Referring to Figure 3 In one embodiment, the arrangement angle of the two second light source units 220 is different by a predetermined angle. The predetermined angle can be any angle between 0° and 90°. Preferably, the predetermined angle can be 90°.

[0072] Specifically, as shown in Figure 3 , the second light source unit 220 includes one warm light source 221, one green light source 222 and two neutral light sources 223, and the two neutral light sources 223 are arranged side by side. In this embodiment, the arrangement angle of the second light source unit 220 can refer to the angle between the center line of the two neutral light sources 223 and the longitudinal direction or the transverse direction when the second light source unit 220 is mounted on the light source board 100.

[0073] In other words, as shown inFigure 3 As shown in FIG. 2, the two second light source units 220 are arranged in the light source plate 100 in a manner that the arrangement angle of one of the two second light source units 220 is consistent with the longitudinal direction, and the arrangement angle of the other of the two second light source units 220 is consistent with the transverse direction, i.e. the arrangement angles of the two second light source units 220 are different by 90°. When the two second light source units 220 are installed on the light source plate 100, one of the two second light source units 220 is installed in the light source plate 100 in the arrangement angle consistent with the longitudinal direction, and the other of the two second light source units 220 is installed in the light source plate 100 in the arrangement angle that is rotated by 90° clockwise or counterclockwise on the basis of the one of the two second light source units 220.

[0074] It can be understood that in other embodiments, the arrangement angles of the two second light source units 220 can be different by other angles, such as 45° or 60°, etc.

[0075] Alternatively, in other embodiments, the arrangement angles of the two second light source units 220 can also be consistent. That is, the arrangement angles of the two second light source units 220 can both be consistent with the longitudinal direction, or both be consistent with the transverse direction.

[0076] In the embodiment, by making the arrangement angles of the two first light source units 210 different by a predetermined angle, and / or making the arrangement angles of the two second light source units 220 different by a predetermined angle, not only the arrangement manners of the first light source units 210 and the second light source units 220 in the central light emitting area 110 are more flexible, but also the light rays of different colors between the first light source units 210 and the second light source units 220 can be more variously interwoven and matched, thereby being beneficial to improving the light emitting uniformity of the LED light source 10 and enhancing the camera effect of the LED light source 10.

[0077] Referring to FIG. 3, Figure 1 and Figure 2 As shown in FIG. 3, in the present application, a plurality of annular light emitting areas 120 are arranged side by side on the outside of the central light emitting area 110, and the center of each annular light emitting area 120 coincides with the center of the light source plate 100. Among them, each annular light emitting area 120 can be in the shape of a circular ring. For example, as shown in FIG. 4, five annular light emitting areas 120 in the shape of a circular ring are arranged on the light source plate 100. Figure 2 The five annular light emitting areas 120 are concentrically arranged with the center of the light source plate 100 as the center.

[0078] It can be understood that in other embodiments, each annular light emitting area 120 can also be in the shape of a rectangular ring or an elliptical ring.

[0079] Since the plurality of annular light emitting areas 120 are arranged concentrically and side by side outside the central light emitting area 110, the light emitting of the central light emitting area 110 and the innermost annular light emitting area 120 can influence each other, and the light emitting of any two adjacent annular light emitting areas 120 can also influence each other, so that the light emitted in each area from inside to outside of the light source plate 100 can be fully and naturally interwoven and mixed, so that the light mixing effect of the LED light source 10 is better, and the light emitting uniformity is higher.

[0080] As shown in Figure 2 , the first light source units 210 and the second light source units 220 are alternately arranged in each annular light emitting area 120, and the first light source units 210 and the second light source units 220 in each annular light emitting area 120 are arranged in a ring array with the center of the light source plate 100.

[0081] Since the plurality of annular light emitting areas 120 are arranged concentrically and side by side, and the first light source units 210 and the second light source units 220 in each annular light emitting area 120 are arranged in a ring array with the center of the light source plate 100, so that the distribution of the first light source units 210 and the second light source units 220 arranged in the plurality of annular light emitting areas 120 is more regular and uniform, which is beneficial to improve the light mixing effect. Moreover, the first light source units 210 and the second light source units 220 in each annular light emitting area 120 are alternately arranged, so that the light of different colors in the first light source units 210 and the second light source units 220 in each annular light emitting area 120 can be better interwoven and fused, and in addition, the light of different colors in the first light source units 210 and the second light source units 220 in any two adjacent annular light emitting areas 120 can also be interwoven and matched, so that the light mixing effect of the light source plate 100 can be further improved, and the phenomenon of local color concentration or color discontinuity can be avoided, thereby effectively improving the light emitting uniformity of the LED light source 10.

[0082] The LED light source of the embodiment of the present application, wherein the central light emitting area and the plurality of annular light emitting areas form a structural hierarchy from inside to outside, so that the plurality of light emitting units on the light source plate can present a more regular and symmetrical distribution state. In addition, the plurality of light emitting units include the first light source units and the second light source units combined by light sources of different colors, and the first light source units and the second light source units are distributed in the central light emitting area and the plurality of annular light emitting areas, so that the light of different colors in different areas can reflect and superimpose each other, avoiding the occurrence of uneven color display in some areas. Therefore, the light mixing effect of the LED light source is better, the light emitting uniformity is higher, and the lighting demand of the photographic camera light can be met.
