Description

LED light source

[0001] This application claims priority to Chinese Patent Application No. 202520166221.X, filed on January 23, 2025, entitled "LED Light Source", the whole or part of which is incorporated herein by reference. Technical Field

[0002] This application relates to the field of lighting equipment technology, and in particular to an LED light source. Background Technology

[0003] In modern photography and videography, LED lights are often used as auxiliary light sources to achieve better image quality. To adjust the color of the light source, LED lights typically have up to six different colors installed on their substrate, including red, green, blue, amber, cyan, and lemon yellow.

[0004] However, when these six different colored light sources are mounted on the substrate, the arrangement of these colors can easily lead to uneven color emission in LED photography and video lights. For example, some areas may appear bluish while others appear reddish. Since photography and video lights require high uniformity of light emission color, how to arrange the multi-colored light-emitting chips to improve the uniformity of light color is a major problem in the industry. Summary of the Invention

[0005] This application provides an LED light source, including a substrate. The substrate includes a central light-emitting area and multiple annular light-emitting areas. The central light-emitting area is arranged in the central region of the substrate, and the center of the central light-emitting area coincides with the center of the substrate. Six different colored light sources are arranged in the central light-emitting area, and the number of each color light source is more than one.

[0006] Multiple annular light-emitting areas are arranged side by side outside the central light-emitting area. The center of each annular light-emitting area coincides with the center of the substrate. Three or more different colors of light-emitting sources are arranged in the annular light-emitting areas. The light-emitting sources in the annular light-emitting areas are distributed in a ring array with the center of the substrate.

[0007] In a ring-shaped luminous area, light sources of the same color are separated by light sources of other colors, and light sources of the same color in two adjacent ring-shaped luminous areas are not adjacent.

[0008] In the LED light source, one or more annular light-emitting areas near the edge of the substrate are called the outer light-emitting area, and six different colored light sources are arranged in the outer light-emitting area.

[0009] In the LED light source, the annular light-emitting areas located between the central light-emitting area and the outer light-emitting area are called intermediate light-emitting areas, and three different colors of light-emitting sources are arranged in the intermediate light-emitting areas.

[0010] In the LED light source, along the direction from the central light-emitting area to the outer light-emitting area, the light sources in the intermediate light-emitting areas of the odd-numbered layers have the same color and arrangement, the light sources in the intermediate light-emitting areas of the even-numbered layers have the same color and arrangement, and the color of the light sources in the intermediate light-emitting areas of the odd-numbered layers is different from the color of the light sources in the intermediate light-emitting areas of the even-numbered layers.

[0011] In the LED light source described, the light sources in the intermediate light-emitting areas of the odd-numbered layers are warm light sources, cold light sources, and neutral light sources.

[0012] In the LED light source, in each intermediate light-emitting area located in the odd-numbered layers, the warm light source and the cold light source are separated by the neutral light source.

[0013] In the LED light source, the warm light source, the cold light source, and the neutral light source are arranged in a predetermined order in the intermediate light-emitting areas of the odd-numbered layers.

[0014] In the LED light source described, the light sources in the intermediate light-emitting areas of the even-numbered layers are red light sources, green light sources, and blue light sources.

[0015] In the LED light source, in each intermediate light-emitting area located in even-numbered layers, the green light source and the blue light source are separated by the red light source.

[0016] In the LED light source, the red light source, green light source, and blue light source are arranged in a predetermined order in the intermediate light-emitting areas of the even-numbered layers.

[0017] In the LED light source, six different colored light sources are arranged in a rectangular array in the central light-emitting area.

[0018] In the LED light source, six different colored light sources are arranged in a circular array in the central light-emitting area.

[0019] In the LED light source, in the central light-emitting area, six different colored light sources are arranged in four columns along the longitudinal direction and in four rows along the transverse direction.

[0020] Among them, the six different colored light sources are red light source, green light source, and blue light source, as well as warm light source, cool light source, and neutral light source. The number of red light sources is the same as the number of neutral light sources, and both are twice the number of any other color light source.

[0021] In the LED light source, the green light source and the blue light source are arranged diagonally and located on the outermost side of the matrix.

[0022] The LED light source provided in this application includes a substrate, which comprises a central light-emitting area and a plurality of concentrically arranged annular light-emitting areas. The central light-emitting area is equipped with six different colored light sources, and each annular light-emitting area is equipped with three or more different colored light sources. Furthermore, the light sources in each annular light-emitting area are arranged in a circular array around the center of the substrate. Light sources of the same color in each annular light-emitting area are separated by light sources of other colors, and light sources of the same color in any two adjacent annular light-emitting areas are not adjacent.

[0023] This design creates a layered structure from the inside out, with the central light-emitting area and multiple annular light-emitting areas on the substrate. The clever distribution of different colored light sources across these areas allows the different colors of light to complement and overlap each other, preventing uneven color display in certain areas. This effectively improves the light mixing effect of the light sources on the substrate, enhances the uniformity of LED light emission, and meets the lighting requirements of photographic and video lighting.

Detailed Implementation

[0030] This application provides an LED light source. To make the purpose, technical solution, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0031] Referring to Figure 1, the LED light source 10 according to an embodiment of this application 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 its center point. It is understood that the substrate 100 can also have other shapes, such as rectangular, elliptical, etc.

[0032] As shown in Figure 1, 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.

[0033] It should be noted that, in this application, as shown in Figure 1, the six different colored light sources 140 can be designated as red light source 141 (labeled R), green light source 142 (labeled G), and blue light source 143 (labeled B), as well as warm light source 144 (labeled W), cool light source 145 (labeled C), and neutral light source 146 (labeled L). Specifically, red light source 141 emits red light with a wavelength range of 615nm to 660nm. Green light source 142 emits green light with a wavelength range of 515nm to 540nm. Blue light source 143 emits blue light with a wavelength range of 420nm to 485nm. Warm light source 144 emits warm light, such as amber light, with a wavelength range of 580nm to 600nm. The cold light source 145 is a light source capable of emitting cold light, such as cyan light, with a wavelength range of 485nm to 515nm. The neutral light source 146 is a light source capable of emitting neutral light, such as lemon yellow light, with a wavelength range of 520nm to 580nm.

[0034] It should be noted that in this application, the red light source 141 can be a red light-emitting chip that emits red light when powered on. The green light source 142 can be a green light-emitting chip that emits green light when powered on. The blue light source 143 can be a blue light-emitting chip that emits blue light when powered on. The warm light source 144 can be a light source device that emits amber light by combining a blue light-emitting chip with a corresponding phosphor. The cool light source 145 can be a cyan light-emitting chip that emits cyan light when powered on. The neutral light source 146 can be a light source device that emits lemon-yellow light by combining a blue light-emitting chip with a corresponding phosphor.

[0035] It is understood that in other embodiments, the red light source 141 can also be a light source device composed of a non-red light-emitting chip and a corresponding phosphor, which can emit red light when powered on. Similarly, the green light source 142, blue light source 143 and cold light source 145 can also be in the same way. The warm light source 144 can be a light source device composed of multiple chips, which can emit amber light when powered on. The neutral light source 146 can be a light source device composed of multiple chips, which can emit lemon yellow light when powered on. The specific configuration can be determined according to the situation.

[0036] Referring to Figure 1, 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.

[0037] 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.

[0038] Optionally, as shown in Figure 2, 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.

[0039] 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. That is, there are two green light sources 142, two blue light sources 143, two warm light sources 144, and two cool light sources 145.

[0040] As shown in Figure 2, 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.

[0041] As shown in Figure 2, 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.

[0042] It is understood that, in other embodiments not shown, the positions of green light source 142 and blue light source 143 may also be interchanged with those of warm light source 144 and cold light source 145.

[0043] Referring to Figure 1, 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 may be arranged concentrically with the center of the substrate 100 as the center.

[0044] Each annular light-emitting area 120 may be equipped with three or more light-emitting sources 140 of different colors. The light-emitting sources 140 in each annular light-emitting area 120 may be arranged in a circular 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.

[0045] 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.

[0046] Referring to Figures 1 and 2, in this application, one or more annular light-emitting areas 120 near the edge of the substrate 100 are called outer light-emitting areas 121, and each outer light-emitting area 121 may be equipped with six different colored light sources 140.

[0047] For example, as shown in Figure 2, 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.

[0048] Therefore, by arranging six different colored light sources 140 in the outermost annular light-emitting area 120 of the substrate 100, and by arranging the various colored light sources 140 in a predetermined manner, the different colored light rays can better interweave and blend in the outer light-emitting area 121, resulting in high light emission uniformity in the outer light-emitting area 121. Furthermore, the various colored light rays in the outer light-emitting area 121 can form a better light mixing effect with the various colored light rays in the inner annular light-emitting area 120, which is beneficial to improving the overall light emission uniformity of the LED light source 10.

[0049] It is understood that, in embodiments not shown in this application, the number of outer light-emitting regions 121 may also be set to two or more, depending on the specific circumstances.

[0050] The LED light source 10 of this application has a substrate 100 including a central light-emitting area 110 and a plurality of concentrically arranged annular light-emitting areas 120. The central light-emitting area 110 is provided with six different colored light sources 140, and each annular light-emitting area 120 is provided with three or more different colored light sources 140. Furthermore, the light sources 140 in each annular light-emitting area 120 are arranged in a circular array around the center of the substrate 100. Light sources 140 of the same color in each annular light-emitting area 120 are separated by light sources 140 of other colors. Light sources 140 of the same color in any two adjacent annular light-emitting areas 120 are not adjacent, and all six different colored light sources 140 are arranged in the outermost annular light-emitting area 120. Therefore, the arrangement of the central light-emitting area 110 and multiple annular light-emitting areas 120 in the LED light source 10 of this application forms a hierarchical structure from the inside out. Furthermore, the clever distribution of different colored light sources 140 in each area allows the different colors of light in different areas to complement and superimpose each other, avoiding uneven hue display in some areas. Consequently, the LED light source 10 has a better light mixing effect and higher light emission uniformity, meeting the lighting requirements of photographic and video lighting.

[0051] Referring to Figure 3, in one embodiment of this application, each annular light-emitting area 120 located between the central light-emitting area 110 and the outer light-emitting area 121 is an intermediate light-emitting area 122. Each intermediate light-emitting area 122 may contain three different colored light sources 140. Specifically, along the direction from the central light-emitting area 110 to the outer light-emitting area 121, the colors and arrangements of the light sources 140 in the odd-numbered intermediate light-emitting areas 122 can be the same, while the colors and arrangements of the light sources 140 in the even-numbered intermediate light-emitting areas 122 can be the same. Furthermore, the colors of the light sources 140 in the odd-numbered intermediate light-emitting areas 122 are different from those in the even-numbered intermediate light-emitting areas 122.

[0052] For ease of description, as shown in Figures 4 and 5, the intermediate light-emitting areas 122 located in odd-numbered layers are labeled as 122a, and the intermediate light-emitting areas 122 located in even-numbered layers are labeled as 122b.

[0053] As shown in Figures 3 and 4, in the embodiments of this application, there are 5 intermediate light-emitting regions 122a located in the odd-numbered layers. For example, the three different colored light sources 140 in each intermediate light-emitting region 122 located in the odd-numbered layers can be a warm light source 144, a cool light source 145, and a neutral light source 146, respectively.

[0054] Among them, the arrangement of each light source 140 in each intermediate light-emitting area 122 located in the odd-numbered layers can be such that warm light source 144 and cold light source 145 are separated by neutral light source 146.

[0055] Alternatively, in other embodiments not shown, the warm light source 144, the cold light source 145, and the neutral light source 146 in the intermediate light-emitting areas 122 located in the odd-numbered layers can be arranged in a predetermined order. For example, the warm light source 144, the cold light source 145, and the neutral light source 146 can be arranged in the sequential order of warm light, cold light, and neutral light. Alternatively, the warm light source 144, the cold light source 145, and the neutral light source 146 can also be arranged in the sequential order of cold light, warm light, and neutral light, depending on the specific circumstances.

[0056] As shown in Figures 3 and 5, in the embodiments of this application, there are four intermediate light-emitting regions 122b located in even-numbered layers. For example, the three different colored light sources 140 in each intermediate light-emitting region 122 of even-numbered layers can be red light source 141, green light source 142, and blue light source 143, respectively. The arrangement of the light sources 140 in each intermediate light-emitting region 122 of even-numbered layers can be such that green light source 142 and blue light source 143 are separated by red light source 141.

[0057] Alternatively, in other embodiments not shown, the red light source 141, green light source 142, and blue light source 143 in the intermediate light-emitting regions 122 located in even-numbered layers can be arranged in a predetermined order. For example, the red light source 141, green light source 142, and blue light source 143 can be arranged sequentially in the order of red light, green light, and blue light. Alternatively, the red light source 141, green light source 142, and blue light source 143 can also be arranged sequentially in the order of green light, red light, and blue light, depending on the specific circumstances.

[0058] In this embodiment, by making the color and arrangement of the light-emitting light sources 140 in each intermediate light-emitting area 122 of the odd-numbered layers the same, and the color and arrangement of the light-emitting light sources 140 in each intermediate light-emitting area 122 of the even-numbered layers the same, the distribution of the light-emitting light sources 140 in the intermediate light-emitting areas 122 of the odd-numbered layers and the intermediate light-emitting areas 122 of the even-numbered layers can be regular and uniform, thereby improving the light mixing effect.

[0059] Furthermore, the color of the light source 140 in each intermediate light-emitting area 122 of the odd-numbered layers is different from the color of the light source 140 in each intermediate light-emitting area 122 of the even-numbered layers. This allows the light of different colors in the intermediate light-emitting areas 122 of the odd-numbered layers and the intermediate light-emitting areas 122 of the even-numbered layers to interweave and blend with each other, effectively improving the light mixing effect of the light source 140 on the substrate 100 and improving the light emission uniformity of the LED light source 10.

[0060] It is understood that, in embodiments not shown, the types of light sources 140 arranged in the intermediate light-emitting areas 122 of odd-numbered layers and even-numbered layers can be interchanged. For example, the three different colors of light sources 140 arranged in the intermediate light-emitting areas 122 of odd-numbered layers can be red light source 141, green light source 142, and blue light source 143. The three different colors of light sources 140 arranged in the intermediate light-emitting areas 122 of even-numbered layers can be warm light source 144, cool light source 145, and neutral light source 146.

[0061] Alternatively, in other embodiments not shown, each intermediate light-emitting area 122 may also be equipped with four different colored light sources 140. Or, each intermediate light-emitting area 122 may be equipped with five different colored light sources 140, depending on the specific circumstances.

[0062] In this application, the light-emitting side of the substrate 100 can be divided into a light-emitting area and a non-light-emitting area. The central light-emitting area 110 and the multiple annular light-emitting areas 120 mentioned above are all arranged in the light-emitting area of ​​the substrate 100. The non-light-emitting area of ​​the substrate 100 can be used to set other structures of the LED light source 10, such as ribbon cables and electrodes.

[0063] In embodiments not shown in this application, the LED light source 10 may further include positive and negative electrodes. The positive and negative electrodes are used to connect to light-emitting light sources 140 of various colors, respectively. The positive and negative electrodes are disposed in the non-light-emitting area of ​​the substrate 100. Specifically, the positive and negative electrodes may include the positive electrode R+ and negative electrode R- of red light source 141, the positive electrode G+ and negative electrode G- of green light source 142, the positive electrode B+ and negative electrode B- of blue light source 143, the positive electrode A+ and negative electrode A- of warm light source 144, the positive electrode C+ and negative electrode C- of cold light source 145, and the positive electrode L+ and negative electrode L- of neutral light source 146.

[0064] Among them, the light sources 140 of various colors can be connected through a circuit, thereby enabling independent control of the light sources 140 of different colors in the LED light source 10 and flexible control of the light emission mode of the LED light source 10.

[0065] Alternatively, some of the light sources 140 of certain colors may be connected through independent circuits, while other light sources 140 of certain colors may be connected through the same circuit.

[0066] Alternatively, the light sources 140 of various colors can be connected through the same circuit, thereby enabling simultaneous control of the light sources 140 of various colors, depending on the specific circumstances.

[0067] The LED light source of this application embodiment features a central light-emitting area and multiple annular light-emitting areas, forming a hierarchical structure from the inside out. Furthermore, the clever distribution of different colored light sources in each area allows the different colors of light in different areas to complement and superimpose, preventing uneven color display in some areas. Therefore, this LED light source has better light mixing and higher light emission uniformity, meeting the lighting requirements of photographic and video lighting.

[0068] The specific implementation of each of the above operations can be found in the preceding embodiments, and will not be repeated here. It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and concept of this application, and all such changes or substitutions should fall within the protection scope of the appended claims.
