How does a solid state dimmer work?

Some of the problems were solved with the use of solid-state dimmers. Semiconductor dimmers switch on at an angle after the start of each alternating-current half-cycle, so that the voltage applied to lamps is changed by the change in phase angle.

What is a solid state dimmer?

If you want to dim a combination of lights on the same circuit, a solid state dimmer is the best way to dim them.

Why are my dimmable LED lights buzzing?

What is that thing? When the bulb’s power supply isn’t compatible with a dimmer system, it’s usually the reason for LEDs humming. The buzzing noise is actually made by the solid state driver.
