[0027] This application provides an LED light-emitting module 10. Please refer to [link / reference]. Figures 1-5 , Figure 1 This is a schematic diagram showing the arrangement of the light-emitting area 12 in one embodiment of the LED light-emitting module 10 provided in this application. Figure 2 yes Figure 1 A schematic diagram showing the arrangement of symmetrical light-emitting areas 123 in the light-emitting area 12 of the LED light-emitting module 10. Figure 3 yes Figure 1 A schematic diagram showing the arrangement of the LED array 14 in the light-emitting area 12 of the LED light-emitting module 10. Figure 4 yes Figure 2 A schematic diagram showing the arrangement of the first LED subarray 141 and the second LED subarray 142 in the symmetrical light-emitting area 123 of the LED light-emitting module 10. Figure 5 yes Figure 4 Enlarged schematic diagram of the first LED subarray 141 and the second LED subarray 142.
[0028] Combination Figure 1 The LED light-emitting module 10 includes a substrate 11, and the substrate 11 includes a light-emitting area 12. The substrate 11 includes a light-emitting surface and a non-light-emitting surface disposed opposite to each other. The light-emitting area 12 is disposed on the light-emitting surface, and LED chips are mounted on the light-emitting area 12 to form the light source of the LED light-emitting module 10.
[0029] Specifically, the light-emitting surface includes a light-emitting area 12 and a non-light-emitting area 13. The non-light-emitting area 13 is arranged around the light-emitting area 12. The non-light-emitting area 13 is used to install the electrodes, ribbon cables and other structures of the LED light-emitting module 10 to power the LED chips arranged in the light-emitting area 12.
[0030] The light-emitting area 12 is divided into a first light-emitting area 121 and a second light-emitting area 122 that are symmetrical about the axis of symmetry L.
[0031] In some specific embodiments, the substrate 11 may be rectangular, and the light-emitting area 12 may be circular and located at the center of the substrate 11. Of course, the substrate 11 and the light-emitting area 12 may also be arranged in other shapes, which are not specifically limited here.
[0032] Please combine Figure 2 The light-emitting area 12 includes multiple sub-light-emitting areas. The sub-light-emitting areas in the first light-emitting area 121 are defined as first sub-light-emitting areas 1211, and the sub-light-emitting areas in the second light-emitting area 122 are defined as sub-light-emitting areas 1221. The first light-emitting area 121 includes multiple first sub-light-emitting areas 1211, and the second light-emitting area 122 includes multiple second sub-light-emitting areas 1221. A first sub-light-emitting area 1211 and a second sub-light-emitting area 1221 are symmetrically arranged about the axis of symmetry L. Specifically, a first sub-light-emitting area 1211 and a second sub-light-emitting area 1221 symmetrically arranged about the axis of symmetry L form a set of symmetrical light-emitting areas 123.
[0033] Combination Figure 2 , Figure 2 The diagram shows that the number of symmetrical light-emitting regions 123 is six, that is, the first light-emitting region 121 includes six first sub-light-emitting regions 1211, and the second sub-light-emitting region 122 includes six second sub-light-emitting regions 1221. Of course, in other embodiments, the number of symmetrical light-emitting regions 123 is not limited to six.
[0034] Please combine Figure 3 as well as Figure 4 The LED light-emitting module 10 also includes an LED array 14, which is disposed within the light-emitting area 12. The LED array 14 includes one LED sub-array in each sub-light-emitting area. Based on the above, the LED sub-array in the first sub-light-emitting area 1211 is defined as the first LED sub-array 141, and the LED sub-array in the second sub-light-emitting area 1221 is defined as the second LED sub-array 142.
[0035] It should be understood that, Figure 4 Only one first LED subarray 141 and one second LED subarray 142 are shown. Combined Figure 3 Each first sub-light-emitting region 1211 is provided with a first LED sub-array 141, and each second sub-light-emitting region 1221 is provided with a second LED sub-array 142.
[0036] Please combine Figure 5The LED array 14 includes multiple rows of LEDs arranged in a row. Each first sub-light-emitting region 121 has a first LED sub-array 141 containing multiple rows of LEDs arranged adjacently, and each second sub-light-emitting region 122 has a second LED sub-array 142 containing multiple rows of LEDs arranged adjacently. The LEDs in the first LED sub-array 141 and the second LED sub-array 142 are arranged in the same direction.
[0037] Specifically, each LED subarray includes a light color array for adjusting the 12 light colors of the light-emitting area and a color temperature array for adjusting the 12 color temperatures of the light-emitting area. The light color array and the color temperature array are arranged side by side and spaced apart.
[0038] Combination Figure 5 The first LED subarray 141 includes a first color temperature array 1411 and a first light color array 1412, and the second LED subarray 142 includes a second color temperature array 1421 and a second color temperature array 1422. The first color temperature array 1411 and the first light color array 1412 are arranged side by side and spaced apart, and the second color temperature array 1421 and the second light color array 1422 are arranged side by side and spaced apart.
[0039] More specifically, the light color array includes at least one light color column, and the color temperature array includes multiple color temperature columns with different color temperatures.
[0040] The color of light can be classified according to its wavelength. Color temperature is a measure of the color of a light source, determined by comparing its color to that of a theoretically heated blackbody radiator, and can be expressed in Kelvin (K). A multi-color temperature series can refer to multiple series of different color temperatures under the same light color. For example, a multi-color temperature series of different color temperatures could be a series of different white light color temperatures.
[0041] In this case, the number of color columns and color temperature columns in the light color arrays of different LED subarrays can be equal. Figure 5 The number of light color columns in the first light color array 1412 of the first LED subarray 141 is equal to the number of light color columns in the second light color array 1422 of the second LED subarray 142, and both have three columns. The number of color temperature columns in the first color temperature array 1411 of the first LED subarray 141 is equal to the number of color temperature columns in the second color temperature array 1421 of the second subarray 142, and both have two columns.
[0042] It should be understood that Figure 5 This is merely an example showing that the first light color array 1412 has three light color columns, and the first color temperature array 1411 has two color temperature columns. In other embodiments, the first light color array 1412 may include one column, two columns, or three or more columns, and the first color temperature array 1411 may include three columns, four columns, etc.
[0043] Furthermore, the arrangement order of the light color array and color temperature array between the first LED subarray 141 and the second LED subarray 142 is different.
[0044] Combination Figure 4 as well as Figure 5 The first color temperature array 1411 and the first light color array 1412 of the first LED subarray 141 are arranged sequentially along the arrangement direction D, and the second light color array 1422 and the second color temperature array 1421 of the second LED subarray 142 are arranged sequentially along the arrangement direction D. At this time, the arrangement order of the light color array and the color temperature array of the first LED subarray 141 and the second LED subarray 142 is different.
[0045] Furthermore, in all the first LED sub-arrays 141, the first color temperature array 1411 and the first light color array 1412 are arranged in the same order, and the arrangement order can be as follows: Figure 5 The first color temperature array 1411 and the first light color array 1412 are arranged sequentially along the arrangement direction D. In all the second LED sub-arrays, the first color temperature array 1421 and the first light color array 1422 are arranged in the same order, and the arrangement order can be as follows: Figure 5 The second light color array 1422 and the second color temperature array 1421 are arranged sequentially along the arrangement direction D.
[0046] Therefore, the different arrangement order of the light color array and color temperature array between the first LED subarray 141 and the second LED subarray 142, which are symmetrical about the axis of symmetry L, allows the first color temperature array 1411 of the first LED subarray 141 and the second light color array 1422 of the second LED subarray 142 to be light complementary, and the first light color array 1412 and the second color temperature array 1421 to be light complementary, thereby improving the light mixing effect of the LED display module 10.
[0047] Specifically, the light color column includes multiple light color chips of the same light color arranged closely together, and the color temperature column includes multiple color temperature chips of the same color temperature arranged closely together.
[0048] Combination Figure 6 , Figure 6 yes Figure 5 An enlarged schematic diagram of the first LED subarray 141 is shown. Each light color column in the first light color array 1412 includes multiple light color chips 14121 arranged in close proximity, and the light color emitted by the light color chips 14121 in the same light color column is the same. Each color temperature column in the first color temperature array 1411 includes multiple color temperature chips 14111 arranged in close proximity, and the color temperature emitted by the color temperature chips 14111 in the same color temperature column is the same.
[0049] By setting the light color chips in the same light color column to the same light color, the same type of chip can be used in the same light color column. Similarly, by setting the color temperature chips in the same color temperature column to the same color temperature, the same type of chip can be used in the same color temperature column. When the same type of chip is arranged in the light color column and color temperature column, the spacing between the same type of chip can be reduced, achieving a close arrangement of the same type of chip. When the chips are arranged close together in the light color column and color temperature column, more chips can be arranged in the light color column and color temperature column, thereby increasing the luminous power of the LED light-emitting module 10.
[0050] In some specific embodiments, the light color array includes multiple light color columns with different light colors, the arrangement order of the light color columns of the first LED sub-array 141 is different from the arrangement order of the light color columns of the second LED sub-array 142 in the same direction, and / or the arrangement order of the color temperature columns of the first LED sub-array 141 is different from the arrangement order of the color temperature columns of the second LED sub-array 142 in the same direction.
[0051] Combination Figure 5 The first color array 1412 of the first LED subarray 141 and the second color array 1422 of the second LED subarray 142 have the same color columns, for example, the same color columns c, d, e. The first color temperature array 1411 and the second color temperature array 1421 have the same color temperature columns, for example, the same color temperature columns a, b.
[0052] Specifically, the color temperature columns of the first LED subarray 141 and the second LED subarray 142 are arranged in different orders along the arrangement direction D, and the light color columns of the first LED subarray 141 and the second LED subarray 142 are also arranged in different orders along the arrangement direction D. This difference in the arrangement order of the light color columns of the first LED subarray 141 and the second LED subarray 142 along the arrangement direction D can be partial or completely different. The same applies to the color temperature columns. Of course, when both the light color column and the color temperature column include two columns, the different arrangement orders of the light color column or the color temperature column mean that the arrangement orders are reversed.
[0053] More specifically, the arrangement order of the light color columns of the first LED subarray 141 is the same as that of the light color columns of the second LED subarray 142 in the opposite direction, and / or the arrangement order of the color temperature columns of the first LED subarray 141 is the same as that of the color temperature columns of the second LED subarray 142 in the opposite direction. Here, "same in the opposite direction" means "opposite in the same direction".
[0054] Combination Figure 5The light color sequences c, d, and e of the first LED subarray 141 are arranged sequentially in the first direction d1, while the light color sequences e, d, and c of the second LED subarray 142 are arranged sequentially in the arrangement direction D. Therefore, the arrangement order of the light color sequences of the first LED subarray 141 and the second LED subarray 142 in the arrangement direction D is opposite. The color temperature sequences a and b of the first LED subarray 141 are arranged sequentially in the arrangement direction D, while the color temperature sequences b and a of the second LED subarray 142 are arranged sequentially in the arrangement direction D. Therefore, the arrangement order of the color temperature sequences of the first LED subarray 141 and the second LED subarray 142 in the arrangement direction D is opposite.
[0055] Based on the above, the light-emitting area 12 includes multiple sets of symmetrical light-emitting areas 123. The arrangement order of the light color column and color temperature column of different first LED sub-arrays 141 in the multiple sets of symmetrical light-emitting areas 123 is the same in the same direction. The arrangement order of the light color column and color temperature column of different second LED sub-arrays in the multiple sets of symmetrical light-emitting areas 123 is the same in the same direction.
[0056] Please combine Figure 7 , Figure 7 yes Figure 3 The diagram shows an enlarged view of the structure of LED array 14. The color and color temperature columns in the first LED subarray 141 are arranged in the same order (a, b, c, d, e) along the direction D. Similarly, the color and color temperature columns in the different second LED subarrays 142 are arranged in the same order along the same direction, which will not be elaborated further.
[0057] Combination Figure 5 In some specific embodiments, the light color array includes three columns of light color columns, and the color temperature array includes two columns of color temperature columns. For example... Figure 5 As shown, the first light color array 1412 in the first LED subarray 141 includes three light color columns, and the first color temperature array 1411 in the first LED subarray 141 includes two color temperature columns.
[0058] In some more specific embodiments, the three columns of the light color array are red, green, and blue light columns, respectively, to adjust the light color of the light-emitting area 12 by means of the red, green, and blue light columns. The two columns of the color temperature array are a first color temperature column and a second color temperature column, wherein the first color temperature column can be a low color temperature column and the second color temperature column can be a high color temperature column, to adjust the color temperature of the light-emitting area 12 by means of the first color temperature column and the second color temperature column.
[0059] Based on the above, the light-emitting area 12 includes multiple sets of symmetrical light-emitting areas 123. At least one set of symmetrical light-emitting areas 123 has its light color column and color temperature column arranged along the first direction d1, and at least one set of symmetrical light-emitting areas 123 has its light color column and color temperature column arranged along the second direction d2. The first direction d1 and the second direction d2 are perpendicular.
[0060] It should be understood that in the above embodiments, the light color series and color temperature series in the multiple sets of symmetrical light-emitting regions 123 are all arranged along the same direction. In this embodiment, at least two symmetrical light-emitting regions 123 have their light color series and color temperature series arranged in mutually perpendicular directions to achieve complementary light effects between different symmetrical light-emitting regions 123, thereby achieving a better light mixing effect.
[0061] Of course, in other embodiments, although the arrangement directions of the light color column and color temperature column of at least two sets of symmetrical light-emitting regions 123 are different, the arrangement directions are not perpendicular, and no specific limitation is made here.
[0062] Please see Figure 8 , Figure 8 This is a schematic diagram showing the arrangement of the light-emitting area 12 in another embodiment of the LED display module 10 provided in this application.
[0063] In this embodiment, the light-emitting area 12 includes a first area 124, a second area 125, and a third area 126. The second area 125 and the third area 126 are located on both sides of the first area 124. Multiple sets of symmetrical light-emitting areas 123 are respectively disposed in the first area 124, the second area 125, and the third area 126. The light color series and color temperature series of the symmetrical light-emitting areas 123 in the first area 124 are arranged along the first direction d1, and the light color series and color temperature series of the symmetrical light-emitting areas 123 in the second area 125 and the third area 126 are arranged along the second direction d2.
[0064] As shown in the figure, the first region 124 is located in the middle of the light-emitting area 12, and the second region 125 and the third region 126 are located above and below the first region 124, respectively. It should be understood that... Figure 8 The columns in the first region 124 represent the light color column and the color temperature column, totaling five columns. At this time, the first region 124 only shows one symmetrical light emission area 123. Similarly, the second region 125 and the third region 126 also only show one symmetrical light emission area 123.
[0065] Of course, as described above, the first region 124, the second region 125, and the third region 126 may each include multiple symmetrical light-emitting areas 123, and the multiple symmetrical light-emitting areas 123 are symmetrically arranged about the axis of symmetry L. Furthermore, the light-emitting area 12 formed by the first light-emitting area 124, the second light-emitting area 125, and the third light-emitting area 126 is arranged in a circular shape.
[0066] It should be understood that by dividing the light-emitting area 12 into three regions, and setting the arrangement direction of the light color column and color temperature column in at least two regions to be different, the regions with different arrangement directions of the light color column and color temperature column of the light-emitting area 12 can have a better light compensation effect, thereby improving the light mixing effect of the LED light-emitting module 10.
[0067] In conjunction with the above, the LED light-emitting module 10 also includes electrodes, wherein the light color chips of a light color column are connected to the electrodes through the same circuit, and the color temperature chips of a color temperature column are connected to the electrodes through the same circuit, so as to supply power to the light color column and the color temperature column and control their on / off state through the electrodes.
[0068] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
