![]() Let's try to understand the proposed circuity with the following points: Of course this would mean the battery getting drained pretty much earlier than a 5mm LED, but it's still economical than using a two 1.5 cells and not including a joule thief circuit. The concept discussed here remains exactly identical to the usual joule thief configuration, we just replace the normally used 5mm LED with a 1 watt LED. The present article discusses 3 such circuits, however here we replace the traditional 5mm LED with a 1 watt LED. Another Design for Illuminating High Power LEDs. ![]() ![]() Design#3: Illuminating four 1 watt LEDS with 1.5V Cell.Design#2: Illuminating a Blue LED with 1.5V Cell.Design#1: Joule thief 1 watt LED Driver.
