Sure Electronics High Power LED Driver 5W
Wiring 6 leds to this?
I'm new to leds, I want to power 6 blue leds (# 070-505 ). To do so what all would I need. I know i would need an led driver, but which wattage? Also, what power supply would I need and does a power supply plug right into one of these drivers?Also, what wires, and resistors? I have a soldering gun so thats not a problem.
A driver that can handle at least 1.2 watts should do it. Watts is heat so, a 1watt driver will get pretty stressed but a 2 watt driver should be able to handle that heat with no problems. The power supply is what would have to provide 3.5vdc to 4vdc to all six leds 21vdc-24vdc. I must be old school because I've never heard of these drivers. They seem useful and effective, but you don't absolutely need one. If you just want the leds to come on and nothing fancy it could be done with batteries for voltage and a resistor to limit current. The resistor will get hot so it has to be able to handle the wattage. Three 9v batteries in series could be your power supply 27v. A resistor close to 675 ohms that could handle at least one watt would push them pretty good 40ma if I'm not mistaking. Put the resistor between the power supply and positive of leds. Wire 6 leds in parallel + to +, - to - and negative of leds back to the power supply. You could put a switch between power and resistor. Maybe a 1k ohm pot that can handle at least one watt could be used for the resistor then you could dial it in but risk damage if turned down too low. You could use a meter to dial the pot to the desired resistance and then hook it into the system. I am sure someone else out there knows more than I do and my suggestion could have negative results, but it would make 6 of those leds run. Hopefuly this sheds some light on the subject. Seems how parts express has so many cool gizmos it's probably not wise to hold me to those numbers and frankenstein it but it would be a fun little project to tinker with and not really dangerous or costly if something gets too hot.
