When the forward current is 350mA, the color temperature is 5734K, and when the forward current increases to 350mA, the color temperature shifts to 5636K. As the current decreases further, the color temperature changes to a warmer color. Of course these problems in general actual lighting may not be a big problem. However, in the RGB LED system, it will cause color deviation, and the human eye is very sensitive to color deviation, so it is not allowed. Modulating current can cause serious problems that make the constant current source not work, but in practice, modulating light by modulating forward current can cause a more serious problem. LED is usually driven by dC-DC constant current drive power supply, and this kind of constant current drive source is usually divided into boost type or buck type two (of course, there are lift pressure type, but because of low efficiency, expensive and not commonly used).
