[0035] See Figure 1 As shown, the LED light source 10 according to an embodiment of the present invention includes a substrate 100, which includes a central light-emitting area 110 and a plurality of annular light-emitting areas 120. The substrate 100 can be a circular plate, with its center being the center of the circle. It is understood that the substrate 100 can also have other shapes, such as rectangular, elliptical, etc.

[0036] like Figure 1 As shown, the central light-emitting area 110 is arranged in the central region of the substrate 100, and the center of the central light-emitting area 110 coincides with the center of the substrate 100. Six different colored light sources 140 are arranged in the central light-emitting area 110.

[0037] It should be noted that in the present application, the six different color light sources 140 can be red light source 141, green light source 142 and blue light source 143, and warm light source 144, cold light source 145 and neutral light source 146 respectively. Among them, the red light source 141 is a light source capable of emitting red light, and its wavelength range can be 615nm-660nm. The green light source 142 is a light source capable of emitting green light, and its wavelength range can be 515nm-540nm. The blue light source 143 is a light source capable of emitting blue light, and its wavelength range can be 420nm-485nm. The warm light source 144 is a light source capable of emitting warm light such as amber light, and its wavelength range can be 580nm-600nm. The cold light source 145 is a light source capable of emitting cold light such as cyan light, and its wavelength range can be 485nm-515nm. The neutral light source 146 is a light source capable of emitting neutral light such as lemon yellow light, and its wavelength range can be 520nm-580nm.

[0038] It should be noted that in the present application, the red light source 141 can be a red light emitting chip, which can emit red light after being powered on. The green light source 142 can be a green light emitting chip, which can emit green light after being powered on. The blue light source 143 can be a blue light emitting chip, which can emit blue light after being powered on. The warm light source 144 can be a blue light emitting chip combined with corresponding phosphor, which can emit amber light. The cold light source 145 can be a cyan light emitting chip, which can emit cyan light after being powered on. The neutral light source 146 can be a blue light emitting chip combined with corresponding phosphor, which can emit lemon yellow light.

[0039] It can be understood that in other embodiments, the red light source 141 can also be a light source device formed by combining a non-red light emitting chip with corresponding phosphor, which can emit red light after being powered on. Similarly, the green light source 142, the blue light source 143 and the cold light source 145 can also be so; the warm light source 144 can be a light source device formed by combining multiple chips, which can emit amber light after being powered on; the neutral light source 146 can be a light source device formed by combining multiple chips, which can emit lemon yellow light after being powered on, which can be determined according to the specific circumstances.

[0040] Reference is made to Figure 1As shown, six different colored light sources 140 are arranged within the central light-emitting area 110, with at least one of each color. All the light sources 140 within the central light-emitting area 110 can be arranged in a predetermined manner. For example, in one embodiment, all the light sources 140 within the central light-emitting area 110 can be arranged in a rectangular array or a circular array. This results in a more uniform and symmetrical distribution of light sources within the central light-emitting area 110, which is beneficial for improving the light emission uniformity of the central light-emitting area 110, and consequently, for improving the light emission uniformity of the LED light source 10.

[0041] Referring to Figure 2, in one embodiment, in the central light-emitting area 110, six different colored light sources 140 are arranged in four columns along the longitudinal direction and four rows along the transverse direction. That is, all the light sources 140 in the central light-emitting area 110 are arranged in a square matrix, and the total number of all the light sources 140 in the central light-emitting area 110 is 16.

[0042] Specifically, such as Figure 2 As shown, the number of red light sources 141 is the same as the number of neutral light sources 146, and both are twice the number of any other color light source. That is, there are four red light sources 141 and four neutral light sources 146. The red light sources 141 and the neutral light sources 146 can be arranged at the circumferential edges of the square matrix.

[0043] Apart from the red light source 141 and the neutral light source 146, there are two light sources 140 for each of the other colors. For example... Figure 2 As shown, the green light source 142 and the blue light source 143 can be arranged diagonally and located on the outermost side of the matrix. This design ensures that all red light sources 141, all green light sources 142, all blue light sources 143, and all neutral light sources 146 are not close together. This allows different colors of light to interweave and blend, improving the light mixing effect.

[0044] like Figure 2 As shown, the warm light source 144 and the cold light source 145 can be arranged diagonally and located at the innermost part of the matrix. That is, in this embodiment, any light source 140 of any color arranged in the central light-emitting area 110 will be separated by other light sources 140 of different colors, which is conducive to the interweaving and fusion of various colors of light, and helps to improve the light mixing effect and increase the uniformity of light emission.

[0045] See Figure 1As shown, in this application, multiple annular light-emitting regions 120 are arranged side by side outside the central light-emitting region 110, and the center of each annular light-emitting region 120 coincides with the center of the substrate 100. Each annular light-emitting region 120 may be circular in shape. The multiple annular light-emitting regions 120 are all arranged concentrically with the center of the substrate 100 as the center.

[0046] Each annular light-emitting area 120 is equipped with three or more light-emitting sources 140 of different colors, and the light-emitting sources 140 in each annular light-emitting area 120 are arranged in a ring array around the center of the substrate 100. Light-emitting sources 140 of the same color in each annular light-emitting area 120 are separated by light-emitting sources 140 of other colors, and light-emitting sources 140 of the same color in any two adjacent annular light-emitting areas 120 are not adjacent.

[0047] Because multiple annular light-emitting areas 120 are arranged concentrically side by side, and the light-emitting sources 140 in each annular light-emitting area 120 are distributed in a circular array around the center of the substrate 100, the distribution of the light-emitting sources 140 arranged in the multiple annular light-emitting areas 120 is relatively regular and uniform, which is beneficial to improving the light mixing effect. In addition, each annular light-emitting area 120 is equipped with light-emitting sources 140 of multiple colors, and light-emitting sources 140 of the same color are separated. Light-emitting sources 140 of the same color are not adjacent between adjacent annular light-emitting areas 120, so that different colors of light can better interweave and blend with each other, avoiding the phenomenon of excessive local color concentration or color discontinuity, thereby effectively improving the light mixing effect of the light-emitting sources 140 on the substrate 100 and improving the light emission uniformity of the LED light source 10.

[0048] See Figure 1 and Figure 2 As shown in this application, one or more annular light-emitting areas 120 near the edge of the substrate 100 are outer light-emitting areas 121, and each outer light-emitting area 121 is provided with six different colored light sources 140.

[0049] For example, such as Figure 2 As shown, there is one outer light-emitting area 121. Six different colored light sources 140 are arranged within this single outer light-emitting area 121. It can be understood that the arrangement of the six different colored light sources 140 within this single outer light-emitting area 121 must satisfy the requirement mentioned above that light sources 140 of the same color are separated from light sources 140 of other colors, and also must satisfy the requirement that they are not adjacent to light sources 140 of the same color in the adjacent annular light-emitting area 120.

[0050] Therefore, by arranging six different color light emitting sources 140 in the outermost annular light emitting area 120 of the substrate 100, and arranging the light emitting sources 140 of various colors in a predetermined manner, the light of different colors can be better interwoven and fused in the outer light emitting area 121, so that the light emitting uniformity of the outer light emitting area 121 is high. The light of various colors in the outer light emitting area 121 can form a better light mixing effect with the light of various colors in the inner annular light emitting areas 120, which is beneficial to improve the overall light emitting uniformity of the LED light source 10.

[0051] It can be understood that in embodiments not shown in the present application, the number of outer light emitting areas 121 can also be two, and more than two, which can be determined according to the situation.

[0052] The LED light source 10 of the present application includes a central light emitting area 110 and a plurality of annular light emitting areas 120 arranged concentrically, the central light emitting area 110 is arranged with six different color light emitting sources 140, and each annular light emitting area 120 is arranged with three or more different color light emitting sources 140. Moreover, the light emitting sources 140 in each annular light emitting area 120 are distributed in a ring array with the center of the substrate 100 as the center, the light emitting sources 140 of the same color in each annular light emitting area 120 are separated by light emitting sources 140 of other colors, the light emitting sources 140 of the same color in any two adjacent annular light emitting areas 120 are not adjacent, and the light emitting sources 140 of all six different colors are arranged in the outermost annular light emitting area 120. Therefore, the central light emitting area 110 and the plurality of annular light emitting areas 120 of the LED light source 10 of the present application form a structure hierarchy from the inside to the outside, and the clever distribution of light emitting sources 140 of different colors in each area makes the light of different colors in different areas reflect and superimpose on each other, avoiding the occurrence of color phase unevenness in some areas. Therefore, the light mixing effect of the LED light source 10 is better, the light emitting uniformity is higher, and the lighting demand of the photographic camera light can be met.

[0053] Referring to Figure 3 In an embodiment of the present application, the annular light emitting areas 120 between the central light emitting area 110 and the outer light emitting area 121 are intermediate light emitting areas 122, and each intermediate light emitting area 122 is arranged with three different color light emitting sources 140. Among them, along the direction from the central light emitting area 110 to the outer light emitting area 121, the colors and arrangements of the light emitting sources 140 in the odd-numbered intermediate light emitting areas 122 are the same, the colors and arrangements of the light emitting sources 140 in the even-numbered intermediate light emitting areas 122 are the same, and the colors of the light emitting sources 140 in the odd-numbered intermediate light emitting areas 122 are different from the colors of the light emitting sources 140 in the even-numbered intermediate light emitting areas 122.

[0054] For ease of description, as shown in Figure 4 and Figure 5 Each of the intermediate light emitting areas 122 located at the odd layers is denoted as 122a, and each of the intermediate light emitting areas 122 located at the even layers is denoted as 122b.

[0055] As shown in Figure 3 and Figure 4 In the embodiments of the present application, the number of the intermediate light emitting areas 122a located at the odd layers is 5. For example, the three different colors of the light emitting sources 140 in each of the intermediate light emitting areas 122 located at the odd layers are warm light sources 144, cold light sources 145 and neutral light sources 146, respectively.

[0056] In each of the intermediate light emitting areas 122 located at the odd layers, the arrangement of the light emitting sources 140 can be that the warm light sources 144 and the cold light sources 145 are separated by the neutral light sources 146.

[0057] Alternatively, in other embodiments not shown, in each of the intermediate light emitting areas 122 located at the odd layers, the warm light sources 144, the cold light sources 145 and the neutral light sources 146 are arranged in a predetermined order. For example, the warm light sources 144, the cold light sources 145 and the neutral light sources 146 can be arranged in the order of warm light, cold light and neutral light in sequence. Alternatively, the warm light sources 144, the cold light sources 145 and the neutral light sources 146 can be arranged in the order of cold light, warm light and neutral light in sequence, which can be determined according to the specific situation.

[0058] As shown in Figure 3 and Figure 5 In the embodiments of the present application, the number of the intermediate light emitting areas 122b located at the even layers is 4. For example, the three different colors of the light emitting sources 140 in each of the intermediate light emitting areas 122 located at the even layers are red light sources 141, green light sources 142 and blue light sources 143, respectively. In each of the intermediate light emitting areas 122 located at the even layers, the arrangement of the light emitting sources 140 can be that the green light sources 142 and the blue light sources 143 are separated by the red light sources 141.

[0059] Alternatively, in other embodiments not shown, in each of the intermediate light emitting areas 122 located at the even layers, the red light sources 141, the green light sources 142 and the blue light sources 143 are arranged in a predetermined order. For example, the red light sources 141, the green light sources 142 and the blue light sources 143 can be arranged in the order of red light, green light and blue light in sequence. Alternatively, the red light sources 141, the green light sources 142 and the blue light sources 143 can be arranged in the order of green light, red light and blue light in sequence, which can be determined according to the specific situation.

[0060] In the present embodiment, the color and arrangement of the light emitting sources 140 in each of the intermediate light emitting regions 122 in the odd layers are the same, and the color and arrangement of the light emitting sources 140 in each of the intermediate light emitting regions 122 in the even layers are the same, so that the distribution of the light emitting sources 140 in the odd layer intermediate light emitting regions 122 and the even layer intermediate light emitting regions 122 is regular and uniform, thereby facilitating the light mixing effect.

[0061] In addition, the color of the light emitting sources 140 in each of the intermediate light emitting regions 122 in the odd layers is different from the color of the light emitting sources 140 in each of the intermediate light emitting regions 122 in the even layers, so that the light of different colors in the odd layer intermediate light emitting regions 122 and the even layer intermediate light emitting regions 122 can interweave and blend with each other, effectively improving the light mixing effect of the light emitting sources 140 on the substrate 100 and improving the light emitting uniformity of the LED light source 10.

[0062] It can be understood that in other embodiments not shown, the types of the light emitting sources 140 arranged in the odd layer intermediate light emitting regions 122 and the even layer intermediate light emitting regions 122 can also be interchanged. For example, the three different colors of the light emitting sources 140 arranged in each of the intermediate light emitting regions 122 in the odd layers can be red light sources 141, green light sources 142 and blue light sources 143. The three different colors of the light emitting sources 140 arranged in each of the intermediate light emitting regions 122 in the even layers can be warm light sources 144, cold light sources 145 and neutral light sources 146.

[0063] Alternatively, in other embodiments not shown, four different colors of light emitting sources 140 can also be arranged in each of the intermediate light emitting regions 122. Alternatively, five different colors of light emitting sources 140 can also be arranged in each of the intermediate light emitting regions 122, which can be determined according to the specific circumstances.

[0064] In the present application, the light emitting side of the substrate 100 can be divided into a light emitting region and a non-light emitting region. The central light emitting region 110 and the plurality of annular light emitting regions 120 in the above are arranged in the light emitting region of the substrate 100. The non-light emitting region of the substrate 100 can be used to set other structures of the LED light source 10, such as a wire and an electrode.

[0065] In an embodiment not shown in the present application, the LED light source 10 can further include positive and negative electrodes. The positive and negative electrodes are used to connect with the light emitting sources 140 of various colors respectively. The positive and negative electrodes are arranged in the non-light emitting area of the substrate 100. The positive and negative electrodes can include the positive electrode R+ and the negative electrode R- of the red light source 141, the positive electrode G+ and the negative electrode G- of the green light source 142, the positive electrode B+ and the negative electrode B- of the blue light source 143, and the positive electrode A+ and the negative electrode A- of the warm light source 144, the positive electrode C+ and the negative electrode C- of the cold light source 145, and the positive electrode L+ and the negative electrode L- of the neutral light source 146.

[0066] The light emitting sources 140 of various colors can be connected through a line loop respectively, so that the independent control of the light emitting sources 140 of different colors in the LED light source 10 can be realized, and the flexible control of the light emitting mode of the LED light source 10 can be realized.

[0067] Alternatively, the light emitting sources 140 of some colors are connected through independent line loops respectively, and the light emitting sources 140 of other colors are connected through the same line loop.

[0068] Alternatively, the light emitting sources 140 of various colors can be connected through the same line loop, so that the simultaneous control of the light emitting sources 140 of various colors can be realized, which can be determined according to the situation.

[0069] In the LED light source of the embodiment of the present application, the central light emitting area and the plurality of annular light emitting areas form a structure level from inside to outside, and the light emitting sources of different colors are distributed in the areas in a clever manner, so that the light of different colors in different areas can be reflected and superimposed on each other, and the situation that the hue displayed by some areas is not uniform can be avoided. Therefore, the light mixing effect of the LED light source is better, the light emitting uniformity is higher, and the illumination demand of the photographic and video camera light can be met.

[0070] The above embodiments are only exemplary descriptions of structures, and the structures in the embodiments are not fixedly combined structures. In the case of no structural conflict, the structures in the plurality of embodiments can be used in any combination.

[0071] Although the present application has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present application can be embodied in various forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited to any particular details, but are to be interpreted broadly within the spirit and scope of the appended claims, therefore, all changes and modifications that fall within the scope of the claims or their equivalents should be covered by the appended claims.
