Nettet12. jun. 2008 · When using LEDs with maximum forward voltage of 3.4 to 4 V, the input voltage from the battery will be either equivalent or above the necessary driving voltage. Hence, a current regulated step-up converter will be needed to drive LED either connected in parallel or in series.

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. horizon power annual report 2021NettetLED Resistor Calculator.
