How does triac dimming?

When the lamp needs to be dimmed by the triac signal, the input voltage waveform in the circuit deviates from the sine wave due to the change of the triac conduction angle, which changes the effective value of the input voltage, and the dimming is realized by changing the voltage. During the triac turn-on process, a switch in the triac potentiometer can adjust the voltage divider ratio of the inte...

What can be called a dimming power supply?

We know that every LED lamp needs an LED drive power to provide constant current drive or constant voltage drive. Later, in order to meet people's needs for dimming and color adjustment of LED lights, Ouches The power designer adds a dimming and color adjustment function to the LED drive power, so it is called the LED dimmable drive power. The LED dimmable driver power supply is a functional integ...

What is a LED driver power supply?

The excellent led drivers are standalone powers source that adjusts the power required by the LED or LED array. Light-emitting diodes (LEDs) are low energy consumption lighting equipment, with long life and low energy consumption, so special power supply is needed. one of the advantages of LEDs is that they are energy efficient - they don't require a lot of power to work. LEDs actually operate usi...

What are the characteristics of constant current and constant voltage power supplies?

led driver constant current are designed to specify a range of output voltages and a fixed output current (mA). LEDs rated to operate on constant current drivers require A specified current supply, usually in milliamperes (mA) or amperes (A). Constant current LED drivers have similar power ratings, but have fixed amplifier (a) or milliampere (MA) values for voltage or maximum voltage range. LED eq...
