LED light source module and LED light source
[0001] This application claims priority to Chinese Patent Application No. 2025201316927, filed on January 20, 2025, entitled "LED Light Source Module and 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 module and 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 emitted light, LED lights now incorporate multiple colored LED chips, such as RGB chips, on their light source boards.
[0004] However, when multiple different colored LED chips are mounted on the light source board, the arrangement of these chips 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 a high degree of color uniformity, how to arrange multiple colored LED chips to improve the uniformity of the light color is a major problem in the industry. Summary of the Invention
[0005] In a first aspect, embodiments of this application provide an LED light source module, including:
[0006] The light source board includes a first light-emitting area and a second light-emitting area, which are symmetrically arranged about an axis of symmetry extending longitudinally and passing through the center of the light source board.
[0007] Multiple light-emitting units are arranged in an array on a light source board. The multiple light-emitting units are arranged in multiple rows along the longitudinal direction, and the multiple light-emitting units are symmetrically distributed in the first light-emitting area and the second light-emitting area.
[0008] The light-emitting unit includes a red light source device, a green light source device, and a blue light source device, which are distributed in a predetermined manner.
[0009] In the first light-emitting area, the three light-emitting units in each light-emitting unit have the same distribution position and orientation, and the three light-emitting units in each light-emitting unit in the second light-emitting area have the same distribution position and orientation. The three light-emitting units in the first light-emitting area have opposite distribution orientations to the three light-emitting units in the second light-emitting area, which are symmetrical about the axis of symmetry.
[0010] In the LED light source module, the light-emitting units located in the same row are spaced apart from each other.
[0011] In the LED light source module, the LED light source module also includes multiple warm and cool light units, and at least one warm and cool light unit is arranged in the interval between any two adjacent light-emitting units in the same row.
[0012] In the LED light source module, the warm and cool light unit includes a cold light source device.
[0013] In the LED light source module, the warm and cool light unit includes a warm light source device.
[0014] In the LED light source module, the warm and cool light units are arranged side by side along the axis of symmetry.
[0015] In the LED light source module, the warm and cool light units are arranged at intervals along the circumference of the light source plate at the edge of the light source plate.
[0016] In the LED light source module, the spacing between any two adjacent light-emitting units in the same row is equal.
[0017] In the LED light source module, the spacing between any two adjacent light-emitting units in the same row is not equal.
[0018] In the LED light source module, the light-emitting units are arranged side by side along the axis of symmetry.
[0019] A central axis extends laterally from the center of the light source board. The three light source devices in each light-emitting unit located above the central axis and arranged on the axis of symmetry have the same distribution position and orientation. Similarly, the three light source devices in each light-emitting unit located below the central axis and arranged on the axis of symmetry have the same distribution position and orientation.
[0020] The three light source devices in the light-emitting unit located above the central axis and arranged on the axis of symmetry are oriented in the opposite direction to the three light source devices in the light-emitting unit located below the central axis and arranged on the axis of symmetry.
[0021] In the LED light source module, the light-emitting units are arranged side by side along the axis of symmetry, and the distribution position and orientation of the three light-emitting devices in these light-emitting units are the same as those of the three light-emitting devices in the light-emitting units located in the same row in the first light-emitting area.
[0022] In the LED light source module, the light-emitting units are arranged side by side along the axis of symmetry, and the distribution position and orientation of the three light-emitting devices in these light-emitting units are the same as those of the three light-emitting devices in the light-emitting units located in the same row in the second light-emitting area.
[0023] In the LED light source module, the two light-emitting units in any two adjacent rows are staggered.
[0024] In the LED light source module, the red light source device, green light source device and blue light source device in the light-emitting unit are arranged in a triangular pattern.
[0025] Secondly, embodiments of this application also provide an LED light source, including a substrate and an LED light source module as described in any of the above claims, wherein a light source board is mounted on the surface of the substrate, and positive and negative electrodes are respectively provided on the substrate for connection to various light source devices.
[0026] The LED light source module and LED light source provided in this application include a light source board and multiple light-emitting units. The number of light-emitting units in the left and right regions of the light source board, bounded by the axis of symmetry, are equal, their positions are symmetrical, and they can be evenly arranged, which helps to improve the light emission uniformity of the LED light source module to meet the light emission requirements of photographic and video lights.
[0027] Furthermore, the light source devices of each light-emitting unit in the first light-emitting area have the same distribution position and orientation, and the light source devices of each light-emitting unit in the second light-emitting area have the same distribution position and orientation. However, the orientation of the light source devices in the first light-emitting area is opposite to that in the second light-emitting area. Therefore, the left and right sides of the light source board each have corresponding light-emitting layouts, and the left and right sides of the light source board provide uniform and opposite light color effects. This helps improve the overall light mixing effect of the light source board, avoids uneven hue display in some areas, and effectively improves the light emission uniformity of the LED light source module, meeting the lighting requirements of photographic and video lights.

[0034] This application provides an LED light source module and 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.
[0035] This application provides an LED light source 10, including a substrate 101 and an LED light source module 100, wherein the LED light source module 100 is mounted on one side surface of the substrate 101. The substrate 101 has a light-emitting side and a backlight side disposed opposite to the light-emitting side, and the LED light source module 100 is disposed on the light-emitting side surface of the substrate 101.
[0036] The specific embodiments of the LED light source module 100 of this application will be described in detail below with reference to the accompanying drawings.
[0037] Referring to Figures 1 to 3, an LED light source module 100 according to an embodiment of this application includes a light source board 110 and a plurality of light-emitting units 120. The light source board 110 includes a first light-emitting area 111 and a second light-emitting area 112, which are symmetrically arranged about an axis of symmetry 113 extending longitudinally and passing through the center of the light source board 110.
[0038] For example, the light source board 110 can be a circular light source board, with its center being the center of the circle. It is understood that the light source board 110 can also have other shapes, such as rectangular, elliptical, etc.
[0039] As shown in Figure 1, with the axis of symmetry 113 as the boundary, the first light-emitting area 111 and the second light-emitting area 112 have the same shape and size. That is, the first light-emitting area 111 and the second light-emitting area 112 can be arranged symmetrically. When the first light-emitting area 111 and the second light-emitting area 112 are symmetrically arranged about the axis of symmetry 113, the first light-emitting area 111 and the second light-emitting area 112 can be arranged adjacent to each other. At this time, the edge of the first light-emitting area 111 coincides with the edge of the second light-emitting area 112, which is conducive to the compact arrangement of the light-emitting units 120 on the light source board 110 and the miniaturization design of the LED light source module 100.
[0040] Referring to Figure 1, a plurality of light-emitting units 120 are arrayed on a light source plate 110, and the plurality of light-emitting units 120 are symmetrically distributed within a first light-emitting area 111 and a second light-emitting area 112. For example, the plurality of light-emitting units 120 may be arranged in multiple rows along the longitudinal direction on the light source plate 110. The plurality of light-emitting units 120 may also be arranged in multiple columns along the transverse direction on the light source plate 110. Furthermore, each light-emitting unit 120 located in the first light-emitting area 111 has a corresponding light-emitting unit 120 located in the second light-emitting area 112 at a position symmetrical about the axis of symmetry 113.
[0041] That is, with the axis of symmetry 113 as the boundary, the light-emitting units 120 in the left and right sides of the light source board 110 can be equal in number, symmetrical in position, and uniformly arranged, which helps to improve the light emission uniformity of the LED light source module 100 to meet the light emission requirements of photography and video lights.
[0042] In this application, the light-emitting unit 120 is an RGB light-emitting unit. Optionally, as shown in FIG1, the light-emitting unit 120 includes a red light source device 121 (identified as R), a green light source device 122 (identified as G), and a blue light source device 123 (identified as B). The red light source device 121, the green light source device 122, and the blue light source device 123 are distributed in a predetermined manner.
[0043] For example, as shown in Figure 1, the red light source device 121, the green light source device 122, and the blue light source device 123 can be arranged in a triangular pattern. For instance, as shown in Figure 1, in the light-emitting unit 120, the red light source device 121 can be located at the upper opening of the triangular pattern, while the green light source device 122 and the blue light source device 123 can be located at the lower two openings of the triangular pattern.
[0044] It is understood that in other embodiments, the red light source device 121, the green light source device 122, and the blue light source device 123 are not limited to the distribution shown in FIG1. The positions of the red light source device 121, the green light source device 122, and the blue light source device 123 can be changed according to specific needs to match the best optics. For example, in each light-emitting unit 120, the blue light source device 123 may be located at the upper opening, while the red light source device 121 and the green light source device 122 may be located at the lower two openings.
[0045] In this embodiment, the light-emitting unit 120 includes red light source device 121, green light source device 122 and blue light source device 123 arranged in a triangular pattern. The light source devices of the light-emitting unit 120 are relatively regular and symmetrical, which can improve the light emission uniformity and consistency of the light-emitting unit 120, thereby helping to improve the light emission uniformity and consistency of the LED light source module 100.
[0046] It is worth noting that, as shown in Figures 1 to 3, in the embodiments of this application, the red light source device 121, green light source device 122, and blue light source device 123 of the light-emitting unit 120 are specifically described in a triangular arrangement. However, this application is not limited to this. In other embodiments not shown, the red light source device 121, green light source device 122, and blue light source device 123 in the light-emitting unit 120 may also be arranged in an "L" shape or an "I" shape, depending on the specific circumstances.
[0047] In this application, each color light source device can be a light-emitting chip of the corresponding color. For example, the red light source device 121 can be a red light-emitting chip that emits red light when powered on. Alternatively, each color light source device can be a light-emitting device capable of emitting light of the corresponding color. For example, the red light source device 121 can be a combination of a non-red light-emitting chip and a corresponding phosphor, as long as it emits red light when powered on. Similarly, the green light source device 122 and the blue light source device 123 are also like this. This application does not impose specific limitations on this.
[0048] In the embodiments of this application, the three light source devices in each light source unit 120 within the first light source region 111 have the same distribution position and orientation. The three light source devices in each light source unit 120 within the second light source region 112 also have the same distribution position and orientation. Furthermore, the three light source devices in the light source unit 120 within the first light source region 111 have opposite orientations to the three light source devices in the light source unit 120 within the second light source region 112, which are located symmetrically about the axis of symmetry 113.
[0049] It should be noted that in the embodiments of the present application, the distribution positions of the three light source devices refer to the positions where each light source device is located in the "pin" structure. For example, the red light source device 121 is located at the position of the upper opening of the "pin", and the green light source device 122 and the blue light source device 123 are respectively located at the positions of the lower two openings of the "pin", with the green light source device 122 on the left and the blue light source device 123 on the right.
[0050] The distribution orientation of the three light source devices refers to the up-and-down relationship between one opening and two openings in the "pin" formed by the three light source devices. For example, when one opening of the "pin" formed by the three light source devices is above, it is the forward direction, and when one opening of the "pin" is below, it is the reverse direction.
[0051] Exemplarily, as shown in FIG. 1, for each light emitting unit 120 in the first light emitting region 111, the red light source device 121 is located at the position of the upper opening of the "pin", and the green light source device 122 and the blue light source device 123 are respectively located at the positions of the lower two openings of the "pin", with the green light source device 122 on the left and the blue light source device 123 on the right; at the same time, the three light source devices of each light emitting unit 120 in the first light emitting region 111 are in the forward distribution mode with one opening above.
[0052] As shown in FIG. 1, for each light emitting unit 120 in the second light emitting region 112, the red light source device 121 is located at the position of the upper opening of the "pin", and the green light source device 122 and the blue light source device 123 are respectively located at the positions of the lower two openings of the "pin", with the blue light source device 123 on the left and the green light source device 122 on the right; at the same time, the three light source devices of each light emitting unit 120 in the second light emitting region 112 are in the reverse distribution mode with one opening below.
[0053] As shown in FIG. 1, for any light emitting unit 120 in the first light emitting region 111, the "pin" formed by its red light source device 121, green light source device 122 and blue light source device 123 is in the forward distribution mode with one opening above. At the same time, for any light emitting unit 120 in the second light emitting region 112, the "pin" formed by its red light source device 121, green light source device 122 and blue light source device 123 is in the reverse distribution mode with one opening below. That is, the distribution orientation of the light source devices of the light emitting units 120 in the first light emitting region 111 is opposite to the distribution orientation of the light source devices of the light emitting units 120 in the second light emitting region 112.
[0054] For example, in specific implementation, by inverting the light emitting unit 120 in the first light emitting region 111 by 180° up and down, the distribution position and orientation of the light source devices of the light emitting unit 120 in the second light emitting region 112 can be obtained.
[0055] It should be noted that the structure of each RGB light-emitting unit can be such that the red light source device 121, the green light source device 122, and the blue light source device 123 are uniformly packaged in a single housing. Therefore, it is only necessary to install each light-emitting unit 120 onto the light source board 110 according to the above arrangement. This makes the production and assembly of the light-emitting unit 120 and the LED light source module 100 more convenient and the structure more compact.
[0056] Alternatively, the red light source device 121, green light source device 122, and blue light source device 123 of each RGB light-emitting unit can each have an independent housing. When manufacturing the LED light source module 100 of this application, each color light source device can be independently mounted on the light source board 110 according to the above arrangement. This facilitates the replacement of a single damaged light source. This application does not impose specific limitations on this aspect.
[0057] In this application, the light source devices of each light-emitting unit 120 in the first light-emitting area 111 are distributed in the same position and orientation, and the light source devices of each light-emitting unit 120 in the second light-emitting area 112 are distributed in the same position and orientation. However, the orientation of the light source devices of each light-emitting unit 120 in the first light-emitting area 111 is opposite to that in the second light-emitting area 112. Therefore, the left and right sides of the light source board 110 can each have a corresponding light-emitting layout, and the left and right sides of the light source board 110 provide uniform and opposite light color effects. This helps improve the overall light mixing effect of the light source board 110, avoids uneven hue display in some areas, and effectively improves the light emission uniformity of the LED light source module 100, meeting the lighting requirements of photographic and video lights.
[0058] Referring to Figure 1, in one embodiment, two light-emitting units 120 in any two adjacent rows are staggered. For example, as illustrated in Figure 1, two light-emitting units 120 located in two adjacent rows are not in the same column along the longitudinal direction, but are staggered from each other. In this embodiment, by arranging the light-emitting units 120 in an alternating manner, the light emission from the light source board 110 can be more comprehensive and uniform, avoiding obvious differences in brightness and darkness, and improving the consistency of illumination.
[0059] Referring to Figure 1, in one embodiment, the light-emitting units 120 located in the same row are spaced apart from each other. For example, the spacing between any two adjacent light-emitting units 120 in the same row can be equal, which facilitates the uniform arrangement of multiple light-emitting units 120 on the light source plate 110 and promotes uniform light emission from the LED light source module 100. Alternatively, in other embodiments not shown, the spacing between any two adjacent light-emitting units 120 in the same row may not be equal.
[0060] Referring to Figures 2 and 3, in one embodiment of this application, the LED light source module 100 further includes a plurality of warm and cool light units 130. The warm and cool light units 130 can be arranged in the interval between any two adjacent light-emitting units 120 in the same row.
[0061] Within the space between any two adjacent light-emitting units 120 in the same row, one or more warm and cool light units 130 can be arranged. For example, referring to Figure 2, two warm and cool light units 130 can be arranged within the space between any two adjacent light-emitting units 120 in the same row. These two warm and cool light units 130 can be arranged closely together longitudinally, and the height of the two warm and cool light units 130 is approximately equal to the height of one light-emitting unit 120. This allows for a more compact arrangement of light sources on the light source plate 110 and improves the regularity and consistency of the light source arrangement.
[0062] It is understood that, in other embodiments not shown, one or more warm and cool light units 130 may also be arranged within the interval between any two adjacent light-emitting units 120 in the same row.
[0063] For example, each warm / cool light unit 130 may include a cool light source device. Alternatively, each warm / cool light unit 130 may include a warm light source device. Or, each warm / cool light unit 130 may include both a cool light source device and a warm light source device. The cool light source device may emit a cool light color, such as white light. The warm light source device may emit a warm light color, such as amber light. Therefore, each warm / cool light unit 130 may emit different light colors, such as cool white light, warm yellow light, or warm white light.
[0064] In this embodiment, by arranging multiple warm and cool light units 130 on the light source board 110, the light emitted by the warm and cool light units 130 can be superimposed with the light emitted by the light-emitting unit 120, thereby effectively improving the light mixing effect and improving the uniformity of the light emission color of the LED light source module 100.
[0065] Referring to Figure 2, in one embodiment, the warm and cool light units 130 are arranged at intervals along the circumference of the light source plate 110 at the edge of the light source plate 110. This allows the RGB light-emitting units on the light source plate 110 to be surrounded by the warm and cool light units 130, enabling the synthesized light emitted by the RGB light-emitting units 120 to be superimposed with the surrounding warm and cool light, thereby effectively improving the light mixing effect and making the emitted color of the LED light source module 100 more uniform.
[0066] Referring to FIG. 2, in one embodiment, the warm and cold light units 130 may be arranged side by side on the symmetry axis 113 along the direction of the symmetry axis 113. For example, the position where the symmetry axis 113 is located is the position where the edge of the first light-emitting area 111 coincides with the edge of the second light-emitting area 112. By longitudinally arranging a plurality of warm and cold light units 130 on the symmetry axis 113, the light emission of the plurality of warm and cold light units 130 can transitionally connect the light emission of the first light-emitting area 111 and the light emission of the second light-emitting area 112, thereby facilitating improving the light mixing effect of the light source board 110 and enhancing the light emission uniformity and consistency of the LED light source module 100.
[0067] As shown in FIG. 2, in one embodiment, the light-emitting units 120 may be arranged side by side on the symmetry axis 113 along the direction of the symmetry axis 113. By longitudinally arranging a plurality of light-emitting units 120 on the symmetry axis 113, the light emission of the plurality of light-emitting units 120 can transitionally connect the light emission of the first light-emitting area 111 and the light emission of the second light-emitting area 112, thereby facilitating improving the light mixing effect of the light source board 110 and enhancing the light emission uniformity and consistency of the LED light source module 100.
[0068] Optionally, the light source board 110 has a central axis 114 that extends horizontally and passes through the center of the light source board 110. The distribution positions and orientations of three light source devices in each of the light-emitting units 120 located above the central axis 114 and arranged on the symmetry axis 113 are the same, and the distribution positions and orientations of three light source devices in each of the light-emitting units 120 located below the central axis 114 and arranged on the symmetry axis 113 are the same. Moreover, the distribution orientations of the three light source devices in the light-emitting units 120 located above the central axis 114 and arranged on the symmetry axis 113 are opposite to the distribution orientations of the three light source devices in the light-emitting units 120 located below the central axis 114 and arranged on the symmetry axis 113.
[0069] For example, as shown in FIG. 2, there are two light-emitting units 120 located above the central axis 114 and arranged on the symmetry axis 113. In these two light-emitting units 120, the red light source device 121 is at the position of the upper opening of the "pin" character, and the green light source device 122 and the blue light source device 123 are respectively at the positions of the lower two openings of the "pin" character, with the green light source device 122 on the left and the blue light source device 123 on the right; at the same time, the three light source devices of these two light-emitting units 120 are all in the forward distribution mode with one opening at the top.
[0070] Moreover, there are also two light-emitting units 120 located below the central axis 114 and arranged on the symmetry axis 113. For these two light-emitting units 120, the red light source device 121 is at the position of the upper opening of the "pin" character, the green light source device 122 and the blue light source device 123 are respectively at the positions of the lower two openings of the "pin" character, and the blue light source device 123 is on the left while the green light source device 122 is on the right. At the same time, the three light source devices of these two light-emitting units 120 are in a reverse distribution mode with one opening at the bottom.
[0071] In this embodiment, the four light-emitting units 120 arranged on the symmetry axis 113 are grouped in pairs and symmetrically arranged about the central axis 114, and the distributions of the light source devices face in opposite directions. Thus, these four light-emitting units 120 can be respectively transitionally connected to the first light-emitting area 111 and the second light-emitting area 112 above the central axis 114 to improve the light mixing effect in the area above the central axis 114, and transitionally connected to the first light-emitting area 111 and the second light-emitting area 112 below the central axis 114 to improve the light mixing effect in the area below the central axis 114. Furthermore, it is beneficial to improve the light emission uniformity and consistency of the light source board 110 and enhance the uniformity of the light emission color of the LED light source module 100.
[0072] It can be understood that in an embodiment not shown in the present application, the multiple light-emitting units 120 arranged in parallel on the symmetry axis 113 may also have the same distribution positions and orientations of the light source devices as those of the light-emitting units 120 in the first light-emitting area 111. And / or, the multiple light-emitting units 120 arranged in parallel on the symmetry axis 113 may have the same distribution positions and orientations of the light source devices as those of the light-emitting units 120 in the second light-emitting area 112.
[0073] For example, assume that there are four light-emitting units 120 arranged in parallel on the symmetry axis 113. Among them, two light-emitting units 120 may have the same distribution positions and orientations of the light source devices as those of the light-emitting units 120 in the first light-emitting area 111, and the other two may have the same distribution positions and orientations of the light source devices as those of the light-emitting units 120 in the second light-emitting area 112. Moreover, the two light-emitting units 120 having the same distribution positions and orientations of the light source devices as those of the light-emitting units 120 in the first light-emitting area 111, and the two light-emitting units 120 having the same distribution positions and orientations of the light source devices as those of the light-emitting units 120 in the second light-emitting area 112 may be arranged alternately along the longitudinal direction on the symmetry axis 113. That is, the four light-emitting units 120 arranged on the symmetry axis 113 may not be symmetric about the above-mentioned central axis 114. Thus, not only can the good light mixing effect be ensured, but also the arrangement mode of each light source on the LED light source module 100 can be made more flexible.
[0074] In this application, the light-emitting side of the substrate 101 is further divided into a light-emitting region and a non-light-emitting region, and the light source board 110 is installed in the light-emitting region. The non-light-emitting region can be used to set other structures of the LED light source 10, such as ribbon cables and electrodes.
[0075] In one example, as shown in Figure 3, positive and negative electrodes 102, respectively connected to various light source devices, are disposed on the substrate 101. The positive and negative electrodes 102 are disposed in non-light-emitting areas. Each positive and negative electrode 102 can be distributed at the corners of the substrate 101, thereby facilitating the arrangement of electrodes and cables.
[0076] The positive and negative electrodes 102 may include RGB positive and negative electrodes. As shown in Figure 3, the RGB positive and negative electrodes may include the positive electrode R+ and negative electrode R- of the red light source device, the positive electrode G+ and negative electrode G- of the green light source device, and the positive electrode B+ and negative electrode B- of the blue light source device. Optionally, each color light source device of the light-emitting unit 120 can be connected through a circuit, thereby enabling independent control of different color light source devices. Therefore, in use, any number and combination of light source devices can be connected to achieve different light effects, realizing flexible control of the light emission mode of the LED light source module 100.
[0077] As shown in Figure 3, the positive and negative electrodes 102 also include cold and warm light positive and negative electrodes. The cold and warm light positive and negative electrodes may include the positive electrode W+ and the negative electrode W- of the cold and warm light source device. Optionally, the cold light source device and / or the warm light source device of the cold and warm light unit 130 can be connected through the same circuit to achieve simultaneous control of the cold and warm light source devices.
[0078] The LED light source module and LED light source of this application embodiment include a light source board and multiple light-emitting units. The number of light-emitting units in the left and right regions of the light source board with the axis of symmetry as the boundary are equal, their positions are symmetrical, and they can be evenly arranged, which helps to improve the light emission uniformity of the LED light source module to meet the light emission requirements of photography and video lighting.
[0079] The light-emitting unit may include red light source devices, green light source devices and blue light source devices arranged in a triangular pattern. The distribution of light source devices in the light-emitting unit is relatively regular and symmetrical, which can improve the light emission uniformity and consistency of the light-emitting unit, thereby helping to improve the light emission uniformity and consistency of the LED light source module.
[0080] Furthermore, the light source devices of each light-emitting unit in the first light-emitting area have the same distribution position and orientation, and the light source devices of each light-emitting unit in the second light-emitting area have the same distribution position and orientation. However, the orientation of the light source devices in the first light-emitting area is opposite to that in the second light-emitting area. Therefore, the left and right sides of the light source board each have corresponding light-emitting layouts, and the left and right sides of the light source board provide uniform and opposite light effects. This helps improve the overall light mixing effect of the light source board, avoids uneven hue display in some areas, and effectively improves the light emission uniformity of the LED light source module, meeting the lighting requirements of photographic and video lights.
[0081] 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.
