Powering 12V LED

Post by **Digit** » Mon Feb 16, 2009 1:26 am

Hi,

I'm looking for a way to supply the 12V LED built into this switch by my 220V powerline. So i need a transformer that can do that. But it has to be small, cause it has to fit in a small box together with the switch. Any ideas for a schematic, a URL to some article, or anything else that can help me further.

Any suggestions are welcome!

PS.
I do have a soldering iron, i even use it sometimes, so it doesn't have to be a finished product.

Conrad is selling modules 230V led powersupply ... see 19 11 65 (low current) and 19-11-78 (20mA supply). You may use only the components and not the printed circuit.

Also on Internet you will find the basis circuit may be this one: http://www.circuitsonline.net/circuits/view/77

Be aware high voltage on the circuit take care of isolation.

Last week there was a nice unit in sale at conrad for 15 euro
It was a unit that you also can dim at 220 volt.
