Luxeon Leds - what would be the simplest constant current driver for them
January 10, 2010
I have just bought 5 of these 3W High-Power LEDs
I could drive them off batteries direct ....
...however i would prefer to feed them with a "constant" but adjustable (350mA-750mA) current.
What would be the simplest circuit i could use ?.....
.... and would there be a way to PWM them?.
3W High-Power White (6000-7000K) 130 Lumens - 140 deg
3.2-3.6V 750 mA /3W/110-130Lumens
Reason 1 for project :- I lost my cycle lamp (for "off track" riding) and would like to light up the forest with these babies.
Reason 2 for project:- There is also a high power RGB version which would be an amazing "psychedelic light up" option for Robots.
