A light-emitting diode ( LED) is a semiconductor device … WebLets start with the series part of the circuit. Lets say we want to run a total of 9 Cree XP-L LEDs at 700mA each with a voltage of 12V dc; the forward voltage of each LED at 700mA is 2.98V dc. Rule number 2 from the series circuit bullet points proves that 12V dc isn’t enough voltage to run all 9 LEDs in-series (9 x 2.98= 26.82V dc). dfawase

The voltage versus current characteristics of an LED is similar to any diode. Current is approximately an exponential function of voltage according to the Shockley diode equation, and a small voltage change may result in a large change in current. If the voltage is below or equal to the threshold no current flows and the result is an unlit LED. If the voltage is too high, the current will exceed the maximum rating, overheating and potentially destroying the LED. WebMar 15, 2024 · It's the same.
