LED driver three in one dimming

Three in one dimming of LED driver refers to three ways: LED 0 / 1-10V dimming, PWM dimming and adjustable resistance dimming.

1. LED driver power supply three in one dimming 0 or 1-10V dimming:

The power supply is designed with a control chip. When connected to a 0-10V dimmer, the output current of the power supply is changed through the change of 0-10V voltage. For example, when the 0-10V dimmer is modulated to 0V, the current drops to 0, and its light brightness is closed (there is a switch function). When the 0-10V dimmer is adjusted up to 10V, the output current will also reach 100% of the power output and the brightness will also reach 100% (the output voltage is constant).

1-10V dimming principle: as described above, only the dimmer is 1-10V: when the resistance dimmer is adjusted to the minimum 1V, the output current is also 10%. If it is adjusted to 10V (the maximum), the output current will reach 100% of the power output and the brightness will be 100% (the output voltage is constant)

Note: 1-10V has no switch function, and the lamp cannot be adjusted to the minimum closing function!

2. LED driver power supply three in one dimming PWM dimming:

PWM dimming, also known as digital dimming, changes the conduction time of forward current through PWM wave to turn on and off led, so as to achieve the effect of brightness adjustment. This method is based on the characteristic that human eyes are not sensitive to brightness flicker, so that the load led is on and off.

3. LED driver power supply three in one dimming Adjustable resistance dimming:

Adjustable resistance dimming is to string resistance into the bulb circuit and change the resistance value to change the circuit current to achieve the purpose of dimming.
