Referring to fig. 2, it is shown in fig. 2 that the number of the symmetric light-emitting areas 123 is six, that is, the first light-emitting area 121 includes six first sub-light-emitting areas 1211, and the second sub-light-emitting area 122 includes six second sub-light-emitting areas 1221. Of course, in other embodiments, the number of symmetric light emitting regions 123 is not limited to six.

Referring to fig. 3 and 4, the LED light emitting module 10 further includes an LED array 14, the LED array 14 is disposed in the light emitting region 12, and the LED array 14 includes a sub-array of LEDs in each sub-light emitting region. In conjunction with 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.

It is to be understood that only one first LED sub-array 141 and one second LED sub-array 142 are shown in fig. 4. Referring to fig. 3, one first LED sub-array 141 is disposed in each first sub-light-emitting region 1211, and one second LED sub-array 142 is disposed in each second sub-light-emitting region 1221.

Referring to fig. 5, the LED array 14 includes LED rows arranged in a plurality of rows, a plurality of LED rows arranged adjacently are included in the first LED sub-array 141 in each first sub-light-emitting area 121, and a plurality of LED rows arranged adjacently are included in the second LED sub-array 142 in each second sub-light-emitting area 122.

Specifically, each LED sub-array includes a light color array for adjusting the light color of the light emitting region 12 and a color temperature array for adjusting the color temperature of the light emitting region 12, and the light color array and the color temperature array are arranged in parallel and at intervals.

More specifically, the light color array comprises at least one light color column, and the color temperature array comprises a plurality of columns of color temperature columns with different color temperatures.

The color of a light color column can be divided by the wavelength of light, the color temperature is a scale representing the light color of a light source, which is determined by comparing its color to a theoretical thermal black body radiator, and can be divided by K (kelvin). The rows of color temperature rows with different color temperatures can be rows of color temperature rows with different color temperatures under the same light color. For example, the plurality of columns of color temperature columns of different color temperatures may be white color temperature columns of different color temperatures.

The light color arrays of different LED sub-arrays can have the same number of light color columns and color temperature columns. Referring to fig. 5, the number of light color columns of the first light color array 1412 of the first LED sub-array 141 is equal to the number of light color columns of the second light color array 1422 of the second LED sub-array 142, and the number of the light color columns is three. The number of color temperature rows of the first color temperature array 1411 of the first LED sub-array 141 is equal to the number of color temperature rows of the second color temperature array 1421 of the second sub-array 142, and the number of the color temperature rows is two.

It should be understood that fig. 5 merely exemplarily illustrates that the number of light color columns of the first light color array 1412 is three, and exemplarily illustrates that the number of color temperature columns of the first color temperature array 1411 is two. In other embodiments, the first color array 1412 may include one column, two columns, three or more columns, and the first color temperature array 1411 may include three or four columns, etc.

Further, the arrangement order between the light color array and the color temperature array of the first LED sub-array 141 and the second LED sub-array 142 is different.

Referring to fig. 4 and 5, the first color temperature array 1411 and the first color temperature array 1412 of the first LED sub-array 141 are sequentially arranged along the arrangement direction D, and the second color temperature array 1422 and the second color temperature array 1421 of the second LED sub-array 142 are sequentially arranged along the arrangement direction D. At this time, the arrangement order between the light color array and the color temperature array of the first LED sub-array 141 and the second LED sub-array 142 is different.

Further, the first color temperature array 1411 and the first color array 1412 in all the first LED sub-arrays 141 are arranged in the same order, and as shown in fig. 5, the first color temperature array 1411 and the first color array 1412 are sequentially arranged along the arrangement direction D. The first color temperature array 1421 and the first color temperature array 1422 in all the second LED sub-arrays are arranged in the same order, and the order of arrangement can be as shown in fig. 5, and the second color temperature array 1422 and the second color temperature array 1421 are arranged in sequence along the arrangement direction D.

Therefore, the arrangement order between the light color arrays and the color temperature arrays of the first LED sub-array 141 and the second LED sub-array 142 symmetric about the symmetry axis L is different, so that the first color temperature array 1411 of the first LED sub-array 141 and the second light color array 1422 of the second LED sub-array 142 are complementary to each other, and the first light color array 1412 and the second color temperature array 1421 are complementary to each other, thereby improving the light mixing effect of the LED display module 10.

Specifically, the light color column comprises a plurality of light color chips which are arranged in a close-fitting manner and have the same light color, and the color temperature column comprises a plurality of color temperature chips which are arranged in a close-fitting manner and have the same color temperature.

Referring to fig. 6, fig. 6 is an enlarged schematic view of the first LED sub-array 141 in fig. 5. Each of the light color columns in the first light color array 1412 includes a plurality of closely arranged light color chips 14121, and the light colors emitted by the light color chips 14121 in the same light color column are the same. Each color temperature row in the first color temperature array 1411 includes a plurality of color temperature chips 14111 arranged in close contact, and the color temperature of light emitted by the color temperature chips 14111 in the same color temperature row is the same.

The same color temperature chips in the same color temperature column are set as chips with the same color temperature, and the same chips can be used in the same color temperature column. When the light color columns are arranged in the color temperature columns by using the same type of chips, the arrangement gaps among the same type of chips can be smaller, and the close arrangement among the same type of chips is realized. When the chips in the color row and the color temperature row are closely arranged, more chips can be arranged in the color row and the color temperature row, thereby improving the light emitting power of the LED light emitting module 10.

In some embodiments, the light color array includes a plurality of light color columns having different light colors, an arrangement order of the light color columns of the first LED sub-array 141 is different from an arrangement order of the light color columns of the second LED sub-array 142 in the same direction, and/or an arrangement order of the color temperature columns of the first LED sub-array 141 is different from an arrangement order of the color temperature columns of the second LED sub-array 142 in the same direction.

Specifically, the color temperature columns of the first LED sub-array 141 and the second LED sub-array 142 are arranged in the arrangement direction D in a different order, and the light color columns of the first LED sub-array 141 and the second LED sub-array 142 are arranged in the arrangement direction D in a different order. The light color columns of the first LED sub-array 141 and the second LED sub-array 142 may be arranged in a partially different order or completely different order in the arrangement direction D. Correspondingly, the same is true for the color temperature column. Of course, when the light color columns or the color temperature columns include two columns, the light color columns or the color temperature columns are arranged in different orders, that is, in opposite orders.

More specifically, the arrangement order of the light color columns of the first LED sub-array 141 is the same as the arrangement order of the light color columns of the second LED sub-array 142 in the opposite direction, and/or the arrangement order of the color temperature columns of the first LED sub-array 141 is the same as the arrangement order of the color temperature columns of the second LED sub-array 142 in the opposite direction. Wherein the arrangement order is the same in opposite directions, i.e. opposite in the same direction.

Referring to fig. 5, the light color columns c, D, and e of the first LED sub-array 141 are sequentially arranged in the first direction D1, and the light color columns e, D, and c of the second LED sub-array 142 are sequentially arranged in the arrangement direction D, so that the light color columns of the first LED sub-array 141 and the light color columns of the second LED sub-array 142 are arranged in the opposite order in the arrangement direction D. Since the color temperature rows a and b of the first LED sub-array 141 are sequentially arranged in the arrangement direction D and the color temperature rows b and a of the second LED sub-array 142 are sequentially arranged in the arrangement direction D, the color temperature rows of the first LED sub-array 141 and the color temperature rows of the second LED sub-array 142 are arranged in the opposite order in the arrangement direction D.

In combination with the above, the light emitting region 12 includes a plurality of sets of symmetric light emitting regions 123, the arrangement order of the light color columns and the color temperature columns of different first LED sub-arrays 141 in the plurality of sets of symmetric light emitting regions 123 is the same in the same direction, and the arrangement order of the light color columns and the color temperature columns of different second LED sub-arrays in the plurality of sets of symmetric light emitting regions 123 is the same in the same direction.

Referring to fig. 7, fig. 7 is an enlarged schematic view of a portion of the LED array 14 in fig. 3. The light color columns and the color temperature columns in the first LED sub-array 141 are arranged in the arrangement direction D in the same order a, b, c, D, e, i.e., in the same direction. Similarly, the light color sequence and the color temperature sequence of the second LED sub-array 142 are the same in the same direction, and are not described again.

As shown in fig. 5, the first light color array 1412 in the first LED sub-array 141 includes three light color columns, and the first color temperature array 1411 in the first LED sub-array 141 includes two color temperature columns.

In some more specific embodiments, the three color columns in the color array are red, green and blue color columns, respectively, so as to adjust the color of the light emitting region 12 through the red color column, the green color column and the blue color column. The two color temperature rows in the color temperature array are a first color temperature row and a second color temperature row, respectively, wherein the first color temperature row may be a low color temperature row, and the second color temperature row may be a high color temperature row, so as to adjust the color temperature of the light emitting region 12 through the first color temperature row and the second color temperature row.

In combination with the above, the light emitting region 12 includes a plurality of sets of symmetric light emitting regions 123, at least one set of light color columns and color temperature columns of the symmetric light emitting regions 123 are arranged along the first direction d1, at least one set of light color columns and color temperature columns of the symmetric light emitting regions 123 are arranged along the second direction d2, and the first direction d1 is perpendicular to the second direction d 2.

In this embodiment, the light color columns and the color temperature columns of at least two symmetric light emitting regions 123 are arranged along the mutually perpendicular directions, so as to realize the complementary effect of light between different symmetric light emitting regions 123, and to achieve a better light mixing effect.

Of course, in other embodiments, although the arrangement directions of the light color columns and the color temperature columns of the at least two sets of symmetric light emitting regions 123 are different, the arrangement directions are not perpendicular, and are not limited herein.

Referring to fig. 8, fig. 8 is a schematic view illustrating a light emitting region 12 of another embodiment of the LED display module 10 provided in the present application.

In the present embodiment, the light emitting region 12 includes a first region 124, a second region 125 and a third region 126, the second region 125 and the third region 126 are respectively located at two sides of the first region 124, the plurality of sets of symmetric light emitting regions 123 are respectively disposed in the first region 124, the second region 125 and the third region 126, the light color sequence and the color temperature sequence of the symmetric light emitting regions 123 in the first region 124 are arranged along the first direction d1, and the light color sequence and the color temperature sequence of the symmetric light emitting regions 123 in the second region 125 and the third region 126 are arranged along the second direction d 2.

As shown, the first region 124 is disposed in the middle of the light emitting region 12, and the second region 125 and the third region 126 are disposed at the upper portion and the lower portion of the first region 124, respectively.

Likewise, the second region 125 and the third region 126 also show only one symmetric light emitting region 123.

The light emitting region 12 including the first light emitting region 124, the second light emitting region 125, and the third light emitting region 126 is arranged in a circular shape.

It should be understood that by dividing the light emitting region 12 into three regions, and setting the arrangement directions of the light color columns and the color temperature columns in at least two regions to be different, a better light compensation effect can be achieved between the regions with different arrangement directions of the light color columns and the color temperature columns of the light emitting region 12, and thus the light mixing effect of the LED light emitting module 10 is improved.
