It can be understood that in order to achieve 2800K-20000K light emission, the real-time power of each color of R, G, B, A, C, L is In the corresponding change, in order to realize that the real-time power of the above-mentioned multi-color LEDs can meet the light emission of 2800K-20000K, the power values of each R, G, B, A, C, and L lamp beads under the light emission parameters of 2800K-20000K can be calculated , for example, you can find the maximum power value of each color lamp bead through list sorting, etc., and take the maximum power value of each lamp bead R, G, B, A, C, L as its power ratio. The specific power ratio can be determined based on the maximum power value selected in the set color temperature section (such as other color temperature sections), and is not limited here.

By setting four blue light beads of different wavelengths and combining them with other lamp beads of different colors, the combined spectrum can achieve a higher overlap with the solar spectrum in the 380-475nm range. It can be understood that if only two If one or more kinds of blue light are mixed, peaks or discontinuous spectra will appear in the 380-475nm segment, resulting in a reduction in the SSI fitting degree. For example, the SSI fitting degree cannot reach 90 and above.

Among them, the row of lamp beads located in the center contains the largest number of lamp beads, and rows of different colors are arranged alternately. For example, rows 5-9 from top to bottom contain the largest number of lamp beads, and the lamp beads in rows 5 to 9 are arranged alternately. Different rows of colored lamp beads. When the number of lamp bead rows is an odd number, the upper and lower rows of lamp beads can be axially symmetrical with the middle row of lamp beads as the symmetry axis. For example, in Figure 2, the 7th row of lamp beads is the symmetry axis, and the 5th row of lamp beads is the axis of symmetry. The lamp beads in the 9th row are symmetrically arranged relative to the 7th row, and the lamp beads in the 6th row and the 8th row are symmetrically arranged relative to the 7th row.
