Good evening..
I'm not sure if the title is misleading or not but I'm not sure exactly how to explain in the title what I'm looking for.
I was thinking about your typical "Joule Thief". I've used them before but was wondering about something. Considering the LED is actually blinking at a very high frequency does it actually run using less current in the long run compared to the same LED running on a direct circuit?
My whole thought comes from the fact that I was messing around with building little garden lamps using 1watt LEDs and a battery pack (they're for carrying around) and I wanted to use the idea that some LED drivers reduce power consumption by blinking the LED. Now the only drivers I've found are for a higher power input but I just want to run the LED off a 3.7V power supply (same as the LED rating) which is why I was wondering if the Joule Thief idea was viable.
Can anyone recommend an idea for what I'm trying to get to?
So it's basically just a Li-ion power supply (3.7V) -> Driver (or whatever you want to call it) -> 1Watt LED.
I'm not too worried if the driver does affect the brightness of the LED too much as I'm expecting it, just as long as it's not by a stupidly high amount. there are also chargers and such involved but that I'll sort out.
Many thanks in advance.
