The first method is to change the current flowing through the LED. In addition to the red LED saturation phenomenon, the general LED tube allows continuous task about 20 mA current, LED brightness and current flow is almost proportional. However, although the current regulation method of changing the flow of LED is relatively simple, it is less and less suitable for rapid and accurate modulation, and more accept the following modulation method.
