led the issue for many reasons, first of all, you want to know how it works can find a solution. I'd like you to. Higher than the threshold, the led panel light is similar to the diode forward VI characteristics. Open below the led outdoor lighting fixtures threshold (white LED turn-on voltage threshold is about 3.5V), pass through the LED current is very small. current forward voltage exponentially increase. This allows the LED designated as a voltage source with a series resistance, with a war...
