Miniature indicator LEDs are normally driven from low voltage DC via a current-limiting resistor. Currents of 2 mA, 10 mA and 20 mA are common. Sub-mA indicators may be made by driving ultrabright LEDs at very low current. Efficiency tends to reduce at low currents, but indicators running on 100 μA are still practical. photography buffetWeb23 de out. de 2024 · How long can a AAA battery power an LED? There is a current of 20mA and a light source. Three 3V LEDs need a power of 3 x 3V x 20mA, but the voltage boosting circuit needs less than 0.1W so the total is 0.28W.
