In other embodiments, the first separation distance W1 may also be smaller than the second separation distance W2.

Please return to the third figure. Each light-emitting unit U1 includes four light-emitting elements 142 distributed in a rhombus. In one embodiment, the light-emitting element 142 is a light-emitting diode. These four light-emitting elements 142 are located at the four corners of the rhombus. However, this case is not limited to this. In other embodiments, each light-emitting unit may also include five light-emitting elements 142 (respectively located at the four corners and the middle of the rhombus), and eight light-emitting elements 142 (respectively located at the four corners and the center of the four sides of the rhombus). point position) or nine light-emitting elements 142 (located respectively at the four corners of the rhombus, the midpoint of the four sides, and the middle of the rhombus), etc.

The light-emitting unit array A1 can be divided into a plurality of first light-emitting unit rows C1 (odd-numbered rows) and a plurality of second light-emitting unit rows C2 (even-numbered rows) that are alternately arranged along the width direction D1.

The pattern conversion module 160 is provided in the housing 120 and includes a pattern scaling unit 162, a pattern dividing unit 164, a first sampling unit 166a, a second sampling unit 166b and a pattern generating unit 168.

The pattern conversion module 160 receives an input pattern file F1 and converts it into an output pattern file F2 according to the configuration of the light-emitting unit U1 on the light-emitting module 140 . The light-emitting control module 180 is electrically connected to the pattern conversion module 160 and the light-emitting module 140 for receiving the output pattern F2 and controlling the light-emitting module 140 to generate light effects according to the output pattern F2.

Please also refer to Figures 5A to 5E. Figures 5A to 5E present the operation process of each component in the pattern conversion module 160 through changes in the image files. Among them, the fifth picture A shows the input picture file F1.

After receiving the input image file F1, the pattern scaling unit 162 adjusts the input image file F1 according to the number of light-emitting units U1 of the light-emitting module 140 and the width-to-height ratio of each light-emitting unit U1. The aspect ratio refers to the ratio of the dimensions of each light-emitting unit U1 along the width direction D1 and the height direction D2. For example, if the light-emitting module 140 can be divided into 68 rows x 28 columns of light-emitting units U1 along the width direction D1 and the height direction D2, and the width-to-height ratio of each light-emitting unit U1 is 2:3, the input image file F1 can be Scaled to 1360*840 pixels, the adjusted image width is 68*2*10=1360 (in pixels), and the adjusted image height is 28*3*10=840 (in pixels) . The reason why the width and height of the image file are enlarged 10 times is to improve the accuracy of calculation.

It is worth noting that the widths of the first grid G1 and the second grid G2 are related to the arrangement of the light-emitting unit array A1. Specifically, the ratio of the first width W3 to the second width W4 of the first grid G1 and the second grid G2 divided by the pattern dividing unit 164 is equal to the ratio of the first separation distance W1 to the second separation distance W2 Compare. For example, as shown in Figure 5C, if the ratio of the first separation distance W1 to the second separation distance W2 is 1:2, the first width W3 will be equal to 20*2*1/(1+2) pixels , the second width W4 will be equal to 20*2*2/(1+2) pixels.

The first sampling unit 166a will sample each first square G1 to generate the first pattern data S1, and the second sampling unit 166b will sample the second square G2 to generate the second pattern data S2. The first sampling unit 166a and the second sampling unit 166b have different sampling methods.

As shown in the figure, four squares 522, 524, 526, 528 appear in the area A of the fifth D figure, corresponding to the 20th to 23rd rows divided by the pattern dividing unit 164. Among them, squares 524 and 528 correspond to odd-numbered rows (that is, the first light-emitting unit row C1) and belong to the aforementioned first square G1. The squares 522 and 526 correspond to the even-numbered rows (that is, the second light-emitting unit row C2) and belong to the aforementioned second square G2.

For squares 524 and 528 (that is, the first square G1), the first sampling unit 166a will capture the pixel data at the midpoint of its side (as shown in the figure, that is, capturing the right side The pixel data of the edge midpoint positions 524a, 528a) is used as a representative to fill the entire square 524, 528. For squares 522, 526 (that is, the second square G2), the second sampling unit 166b will capture the pixel data of its corner position (as shown in the figure, that is, capturing the lower right corner position 522a , pixel data of 526a) as a representative to fill the entire squares 522, 526, and present the pattern shown in Figure 5E.

It is worth noting that the aforementioned sampling method is only an example of this case, and this case is not limited to this. For example, the first sampling unit 166a can also capture the pixel data at the center of the left side of the squares 524 and 528, and the second sampling unit 166b can also capture the pixel data at the lower right corner of the squares 522 and 526. In another embodiment, the first sampling unit 166a may also capture the pixel data at the corners of the squares 524 and 528, and the second sampling unit 166b may also capture the pixel data at the corners of the squares 522 and 526.

Among them, the sixth picture A is a schematic diagram that directly uses mosaic technology to produce light effects based on the input image file F1, and the sixth picture B is a schematic diagram that the light-emitting module 140 of this case produces light effects based on the output image file F2 generated by the pattern conversion module 160. Schematic diagram. In one embodiment, the light-emitting module 140 uses mosaic technology to generate light effects based on the output image file F2.

Please also refer to the input image file shown in Figure 5A. As shown in the figure, compared to Figure 6A, the light effect presented in Figure 6B is closer to the input image file shown in Figure 5A. F1. For example, the input image file shown in Figure 5A has a horizontal line in the lower left corner. Figure A, Figure 6, which directly uses mosaic technology to generate light effects based on the input image file F1, cannot show this horizontal line. Compared with Below, this horizontal line can be displayed through the light effect presented by the output image file F2 generated in this case.
