Can LED lights be dimmed?

Of course.

However, different LED lights have different dimming methods.

For example, the single-chip microcomputer controls the brightness of the LED using PWM technology.

The LED display can display different colors,

The PWM technology is also used to dimming the three-color LED.

Some can be dimmed in two ways.

One is to adjust the capacitance of the resistance-capacitance current-limiting circuit;

The second is the method of controlling the current conduction angle with a thyristor.
