[0039] The LED light source 10 provided by the embodiment of the present application comprises a substrate 101 and an LED light source module 100, and the LED light source module 100 is installed on one side surface of the substrate 101. The substrate 101 has a light-emitting side and a back light side opposite to the light-emitting side, and the LED light source module 100 is arranged on the light-emitting side surface of the substrate 101.
[0040] The specific embodiments of the LED light source module 100 of the present application will be described in detail below with reference to the accompanying drawings.
[0041] Referring to Figures 1 to 3 As shown in the drawings, the LED light source module 100 according to an embodiment of the present application comprises a light source plate 110 and a plurality of light-emitting units 120. The light source plate 110 comprises a first light-emitting area 111 and a second light-emitting area 112, and the first light-emitting area 111 and the second light-emitting area 112 are symmetrically arranged about a symmetry axis 113 extending along the longitudinal direction and passing through the center of the light source plate 110.
[0042] 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.
[0043] like Figure 1 As shown, 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 in a symmetrical shape. 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.
[0044] See Figure 1 Multiple light-emitting units 120 are arrayed on the light source plate 110, and the multiple light-emitting units 120 are symmetrically distributed in the first light-emitting area 111 and the second light-emitting area 112. Specifically, the multiple light-emitting units 120 can be arranged in multiple rows along the longitudinal direction on the light source plate 110. The multiple light-emitting units 120 can 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 symmetrical position about the axis of symmetry 113.
[0045] That is, with the axis of symmetry 113 as the boundary, the number of light-emitting units 120 in the left and right areas of the light source board 110 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 100 to meet the light emission requirements of photography and video lights.
[0046] In this application, the light-emitting unit 120 is an RGB light-emitting unit. Specifically, as shown... Figure 1 As shown, each light-emitting unit 120 includes a red light source device 121 (labeled R), a green light source device 122 (labeled G), and a blue light source device 123 (labeled 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.
[0047] For example, such as Figure 1 As shown, 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 example, as... Figure 1As shown, in the light emitting unit 120, the red light source device 121 can be located at the upper one of the three ports of the "pin" shape, and the green light source device 122 and the blue light source device 123 are respectively located at the lower two ports of the "pin" shape.
[0048] It can be 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 Figure 1 the distribution manner as shown, and can be changed in position according to specific requirements to match the best optical. For example, in each light emitting unit 120, the blue light source device 123 can be located at the upper one port, and the red light source device 121 and the green light source device 122 are respectively located at the lower two ports.
[0049] In the embodiment, each light emitting unit 120 includes the red light source device 121, the green light source device 122 and the blue light source device 123 arranged in a "pin" shape, and the light source devices of each light emitting unit 120 are arranged relatively regular and symmetrical, which can improve the light emitting uniformity and consistency of the light emitting unit 120, thereby facilitating the improvement of the light emitting uniformity and consistency of the LED light source module 100.
[0050] It is worth noting that, as Figures 1 to 3 shown, in the embodiments of the present application, the red light source device 121, the green light source device 122 and the blue light source device 123 of the light emitting unit 120 are taken as an example to be arranged in a "pin" shape. However, the present application is not limited thereto, and in other embodiments not shown, the red light source device 121, the green light source device 122 and the blue light source device 123 in each light emitting unit 120 can also be arranged in an "L" shape or an "I" shape, which can be determined according to the specific circumstances.
[0051] In the present 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 which can emit red light after being powered on. Alternatively, each color light source device can be a light emitting device which can emit 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 can emit red light after being powered on. Similarly, the green light source device 122 and the blue light source device 123 are also the same. For this, the present application is not limited.
[0052] In the embodiment of the present application, the distribution positions and orientations of the three light source devices in each light emitting unit 120 in the first light emitting area 111 are the same. The distribution positions and orientations of the three light source devices in each light emitting unit 120 in the second light emitting area 112 are the same. Moreover, the distribution orientations of the three light source devices in the light emitting unit 120 in the first light emitting area 111 are opposite to those of the three light source devices in the light emitting unit 120 in the second light emitting area 112 at the position symmetrical to the symmetry axis 113.
[0053] It should be noted that, in the embodiment of the present application, the distribution positions of the three light source devices refer to the positions of the light source devices in the "pin" structure. For example, the red light source device 121 is located at the upper one of the "pin", the green light source device 122 and the blue light source device 123 are respectively located at the lower two of the "pin", and the green light source device 122 is on the left and the blue light source device 123 is on the right.
[0054] The distribution orientations of the three light source devices refer to the up-down relationship of the one and two of the "pin" formed by the three light source devices. For example, the one of the "pin" formed by the three light source devices is in the forward direction when it is on the top, and is in the reverse direction when it is on the bottom.
[0055] For example, as shown in FIG. 1, each light emitting unit 120 in the first light emitting area 111 is a "pin" structure, in which the red light source device 121 is located at the upper one of the "pin", the green light source device 122 and the blue light source device 123 are respectively located at the lower two of the "pin", and the green light source device 122 is on the left and the blue light source device 123 is on the right. Moreover, the three light source devices in each light emitting unit 120 in the first light emitting area 111 are in the forward direction, in which the one of the "pin" is on the top. Figure 1
[0056] Figure 1 For example, as shown in FIG. 2, each light emitting unit 120 in the second light emitting area 112 is a "pin" structure, in which the red light source device 121 is located at the upper one of the "pin", the green light source device 122 and the blue light source device 123 are respectively located at the lower two of the "pin", and the blue light source device 123 is on the left and the green light source device 122 is on the right. Moreover, the three light source devices in each light emitting unit 120 in the second light emitting area 112 are in the reverse direction, in which the one of the "pin" is on the bottom.
[0057] Figure 1 As shown, the "pin" shape of the red light source device 121, the green light source device 122 and the blue light source device 123 of any one light emitting unit 120 in the first light emitting area 111 is in a forward distribution mode with the top of the "pin" shape being upward. Meanwhile, the "pin" shape of the red light source device 121, the green light source device 122 and the blue light source device 123 of any one light emitting unit 120 in the second light emitting area 112 is in a reverse distribution mode with the top of the "pin" shape being downward. That is, the distribution direction of the light source devices of the light emitting unit 120 in the first light emitting area 111 is opposite to that of the light emitting unit 120 in the second light emitting area 112.
[0058] For example, in the implementation, the light emitting unit 120 in the first light emitting area 111 can be inverted 180° upside down to obtain the distribution position and direction of the light source devices of the light emitting unit 120 in the second light emitting area 112.
[0059] It should be noted that the structure of each RGB light emitting unit can be that the red light source device 121, the green light source device 122 and the blue light source device 123 are uniformly packaged in one shell. Therefore, each light emitting unit 120 can be mounted on the light source board 110 according to the above arrangement mode. In this way, the production and assembly of the light emitting unit 120 and the LED light source module 100 are more convenient, and the structure is more compact.
[0060] Alternatively, the red light source device 121, the green light source device 122 and the blue light source device 123 of each RGB light emitting unit can each have an independent shell. In the manufacture of the LED light source module 100 of the present application, each color light source device can be independently mounted on the light source board 110 according to the above arrangement mode. In this way, it is convenient to replace a single damaged light source. For this, the present application is not limited in particular.
[0061] In the present application, the distribution position and direction of the light source devices of each light emitting unit 120 in the first light emitting area 111 are the same, the distribution position and direction of the light source devices of each light emitting unit 120 in the second light emitting area 112 are the same, and the distribution direction of the light source devices of each light emitting unit 120 in the first light emitting area 111 is opposite to that of each light emitting unit 120 in the second light emitting area 112. Therefore, the left and right side regions of the light source board 110 can have corresponding light emitting layouts, and the left and right side regions of the light source board 110 can provide uniform and opposite light color effects. Thus, it is beneficial to improve the overall light mixing effect of the light source board 110, avoid the situation that the color phase displayed by some regions is not uniform, and effectively improve the light emitting uniformity of the LED light source module 100, thereby meeting the lighting needs of the photographic camera light.
[0062] Referring to Figure 1In one embodiment, the two light emitting units 120 in any two adjacent rows are staggered. Figure 1 As shown in the example, the two light emitting units 120 in the adjacent two rows are not in the same column in the longitudinal direction, but are staggered. In this embodiment, by staggering the light emitting units 120, the light source board 110 can emit light more comprehensively and uniformly, avoiding obvious light and dark differences, and facilitating the improvement of light consistency.
[0063] Referring to Figure 1 In one embodiment, the light emitting units 120 in the same row are spaced apart from each other. For example, the spacing distance between any two adjacent light emitting units 120 in the same row can be equal, thereby facilitating the uniform arrangement of the light emitting units 120 on the light source board 110 and the uniform light emission of the LED light source module 100. Alternatively, in other embodiments not shown, the spacing distance between any two adjacent light emitting units 120 in the same row can also be unequal.
[0064] Referring to Figure 2 and Figure 3 In one embodiment of the present application, the LED light source module 100 further comprises a plurality of cool and warm light units 130. The cool and warm light units 130 can be arranged in the spacing between any two adjacent light emitting units 120 in the same row.
[0065] In the spacing between any two adjacent light emitting units 120 in the same row, one or more cool and warm light units 130 can be arranged. For example, referring to Figure 2 In the spacing between any two adjacent light emitting units 120 in the same row, two cool and warm light units 130 can be arranged. The two cool and warm light units 130 can be arranged in close contact in the longitudinal direction, and the height of the two cool and warm light units 130 is substantially equal to the height of one light emitting unit 120. Thus, more light sources can be arranged compactly on the light source board 110, and the regularity and consistency of the light source arrangement can be improved.
[0066] It can be understood that in other embodiments not shown, one or more cool and warm light units 130 can also be arranged in the spacing between any two adjacent light emitting units 120 in the same row.
[0067] For example, each cool and warm light unit 130 can comprise a cool light source device. Alternatively, each cool and warm light unit 130 can comprise a warm light source device. Alternatively, each cool and warm light unit 130 can comprise a cool light source device and a warm light source device. The cool light source device can emit cool colors such as white light. The warm light source device can emit warm colors such as amber light. Thus, each cool and warm light unit 130 can emit different colors of light such as cool white light, warm yellow light, or warm white light.
[0068] In this embodiment, by arranging multiple cool and warm light units 130 on the light source plate 110, the light emitted by the cool and warm light units 130 can be superimposed with the light emitted by the light emitting units 120, thereby effectively improving the light mixing effect and improving the uniformity of the light emitting color of the LED light source module 100.
[0069] Referring to Figure 2 In one embodiment, the cool and warm light units 130 are arranged at the edge positions of the light source plate 110 along the circumference of the light source plate 110. Thus, the RGB light emitting units on the light source plate 110 can be in the surrounding circle of the cool and warm light units 130, so that the synthesized light emitted by the RGB light emitting units 120 can be superimposed with the peripheral cool and warm light, thereby effectively improving the light mixing effect and making the light emitting color of the LED light source module 100 more uniform.
[0070] Referring to Figure 2 In one embodiment, the cool and warm light units 130 can also be arranged on the symmetry axis 113 in parallel along the direction of the symmetry axis 113. Specifically, the position of the symmetry axis 113 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 arranging multiple cool and warm light units 130 longitudinally on the symmetry axis 113, the light emitted by the multiple cool and warm light units 130 can transitionally connect the light emitted by the first light emitting area 111 and the light emitted by the second light emitting area 112, thereby facilitating the improvement of the light mixing effect of the light source plate 110 and the improvement of the light emitting uniformity and consistency of the LED light source module 100.
[0071] As Figure 2 shown, in one embodiment, the light emitting units 120 can be arranged on the symmetry axis 113 in parallel along the direction of the symmetry axis 113. By arranging multiple light emitting units 120 longitudinally on the symmetry axis 113, the light emitted by the multiple light emitting units 120 can transitionally connect the light emitted by the first light emitting area 111 and the light emitted by the second light emitting area 112, thereby facilitating the improvement of the light mixing effect of the light source plate 110 and the improvement of the light emitting uniformity and consistency of the LED light source module 100.
[0072] Further, the light source plate 110 has a center axis 114 extending transversely and passing through the center of the light source plate 110, the distribution positions and orientations of the three light source devices in each light emitting unit 120 arranged on the symmetry axis 113 above the center axis 114 are the same, and the distribution positions and orientations of the three light source devices in each light emitting unit 120 arranged on the symmetry axis 113 below the center axis 114 are the same. Moreover, the distribution orientations of the three light source devices in the light emitting unit 120 arranged on the symmetry axis 113 above the center axis 114 are opposite to those of the three light source devices in the light emitting unit 120 arranged on the symmetry axis 113 below the center axis 114.
[0073] For example, asFigure 2 As shown, there are two light emitting units 120 above the central axis 114 and arranged on the symmetry axis 113, the red light source device 121 is located at the upper one of the three openings of the "pin" shape, the green light source device 122 and the blue light source device 123 are respectively located at the lower two of the three openings of the "pin" shape, and the green light source device 122 is on the left and the blue light source device 123 is on the right; meanwhile, the three light source devices of the two light emitting units 120 are in a forward distribution mode with the upper one of the three openings.
[0074] And, there are also two light emitting units 120 below the central axis 114 and arranged on the symmetry axis 113, the red light source device 121 is located at the upper one of the three openings of the "pin" shape, the green light source device 122 and the blue light source device 123 are respectively located at the lower two of the three openings of the "pin" shape, and the blue light source device 123 is on the left and the green light source device 122 is on the right; meanwhile, the three light source devices of the two light emitting units 120 are in a reverse distribution mode with the lower one of the three openings.
[0075] In the embodiment, the four light emitting units 120 arranged on the symmetry axis 113 are arranged in pairs and symmetrically about the central axis 114, and the distribution of the light source devices is opposite. Thus, the four light emitting units 120 can respectively transitionally connect the first light emitting area 111 and the second light emitting area 112 above the central axis 114, improve the light mixing effect of the area above the central axis 114, and transitionally connect the first light emitting area 111 and the second light emitting area 112 below the central axis 114, improve the light mixing effect of the area below the central axis 114, thereby facilitating to improve the light emitting uniformity and consistency of the light source board 110 and improve the uniformity of the light emitting color of the LED light source module 100.
[0076] It can be understood that in the unshown embodiments of the present application, the plurality of light emitting units 120 arranged side by side on the symmetry axis 113 can also have the same distribution position and orientation of the light source devices as the light emitting units 120 in the first light emitting area 111. And / or, the plurality of light emitting units 120 arranged side by side on the symmetry axis 113 can have the same distribution position and orientation of the light source devices as the light emitting units 120 in the second light emitting area 112.
[0077] For example, suppose there are four light-emitting units 120 arranged side-by-side on the axis of symmetry 113. Two of these units may have the same light source device distribution position and orientation as the units 120 in the first light-emitting area 111, and the other two may have the same light source device distribution position and orientation as the units 120 in the second light-emitting area 112. Furthermore, the two units 120 with the same light source device distribution position and orientation as the units 120 in the first light-emitting area 111, and the two units 120 with the same light source device distribution position and orientation as the units 120 in the second light-emitting area 112, may be arranged alternately along the axis of symmetry 113. That is, the four light-emitting units 120 arranged on the axis of symmetry 113 may not be symmetrical about the central axis 114 mentioned above. This not only ensures good light mixing but also allows for more flexible arrangement of the light sources on the LED light source module 100.
[0078] 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.
[0079] In one example, such as Figure 3 As shown, positive and negative electrodes 102, respectively connected to various light source devices, are disposed on the substrate 101. Each positive and negative electrode 102 is disposed in a non-light-emitting area. Each positive and negative electrode 102 can be distributed at the corners of the substrate 101, thereby facilitating the arrangement of electrodes and cables.
[0080] The positive and negative electrodes 102 may include RGB positive and negative electrodes. For example... Figure 3 As shown, 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. That is, each color light source device in each light-emitting unit 120 can be connected through a separate 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.
[0081] like Figure 3 As shown, 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. That is, the cold light source device and / or warm light source device of each cold and warm light unit 130 are connected through the same circuit to achieve simultaneous control of the cold and warm light source devices.
[0082] The LED light source module and the LED light source of the embodiment of the application comprise a light source plate and a plurality of light emitting units.
[0083] The light source device of each light emitting unit can comprise red light source devices, green light source devices and blue light source devices arranged in a triangular shape, and the light source devices of each light emitting unit are arranged symmetrically and regularly, which can improve the light emitting uniformity and consistency of the light emitting unit, thereby improving the light emitting uniformity and consistency of the LED light source module.
[0084] The light source device of each light emitting unit in the first light emitting area has the same distribution position and orientation, the light source device of each light emitting unit in the second light emitting area has the same distribution position and orientation, and the distribution orientation of the light source device of each light emitting unit in the first light emitting area is opposite to that of the light source device of each light emitting unit in the second light emitting area. Therefore, the left and right areas of the light source plate have corresponding light emitting layouts, and the left and right areas of the light source plate provide uniform and opposite light effects. Therefore, the light mixing effect of the whole light source plate can be improved, the situation of uneven color phase in some areas can be avoided, the light emitting uniformity of the LED light source module is effectively improved, and the illumination requirement of the photographic camera lamp is met.
