LED lights with 0-10V dimming when flashing what reason?
After the thyristor is switched on, the current will slowly drop, and when it reaches the thyristor to maintain the current, because this time is very short, if the back circuit is not working, the same will restart.
After the thyristor is switched on, the circuit is not resistive, and the current oscillation occurs due to the capacitance and inductance. When the current oscillates below the thyristor to maintain the current, the thyristor is switched off and then triggered again.
When the input voltage is lowered, the loop current is also reduced to below the SCR holding current, and then the thyristor is turned off.
The main reason for stroboscopic is frequency, and nothing to do with itYou can't adjust the voltage directly by using the common transformer to adjust the voltageThe best dimming method for LED is the PWM, which is actually frequency modulatedLED is not realistic to want to be completely strobe, but the average frequency is above 100HZ, you can't feel the strobe completelyYou use a transformer to tune, the supply or the city's standard 50HZ frequency, 50HZ must have strobe, but some of the lights may not be too obvious, and some obviously.So, if you want to sit with LED lamp dimming, recommended to buy a dimmer, the price may be relatively high, to hundreds of yuan, if your light load is not large, buy a large manufacturer of the wireless light, with remote control, an estimated more than 200.
