![]() A suitable driver transistor, like the 2sd965, 2sc2500, 2sc2655 must be used. My prototype, two 3 watt led matrix 12 leds on each matrix, 24 total leds, approximately 6 watt. Membuat joule thief mini inverter to ac light super hemat skema circuit. You can use a fresh aa battery, but the circuit is special in that it accepts empty batteries.Ī highpower joule thief type circuit to drive a 1watt led from a 1. total power of this led driver depends on numbers of leds connected in parallel. This circuit is pretty efficient and it can power a 1 watt white led quite brightly. Simple 10w high power led driver circuit power led, led. Here a simple 1 watt led driver circuit based on a modified joule thief design, runs on a 1. ![]() I wonder if it is possible to use an electret or an rf antenna that collects enough energy to power an led using a circuit like this. ![]() I got the concept of this circuit few years back from a led torch, which was powered by a single aa battery. Circuit takes 70ma on low brightness and 120ma on high brightness. ![]()
