Running Led At Higher Voltage at Flynn Trenwith blog

Running Led At Higher Voltage. An led draws more current as the voltage being used to run it is increased. So if you increase the voltage across the led above a certain threshold, the current will also increase, burning out the led. If you draw more current than. Matching up the led voltages is critical. Current causes the led to heat up; The idea sounds good but won't work. High current results in too much heat. Leds cannot magically adjust their incoming current to suit the prevailing applied voltage. If you can’t quite reach your peak voltage (169.7 in the example), you’ll probably have to use resistors to make up the difference, which will drop your. 120 v ac) requires electronics between the supply and the devices themselves to provide a dc voltage (e.g. A common way to control brightness is through pulse width modulation (pwm). The voltage only needs to be slightly above the forward voltage rating of the led.
