12AC to 12vdc

[CharlesTT]

Hi guys I am having a bit of a problem trying to get an led light to work. It is a 240v led light that I have replaced the driver with a 12v model that outputs 6v for the leds. The Waterproof transformer I am using  ( it is fit an outside light ) outputs in AC and i'd rather not replace it as it is driving all of the other lights just fine.
Is there a way I can convert its output to DC? Would I have to use a bridge rectifier and if so could you suggest one? or an alternative driver..

Cheers

Charles

A 12 volt ac transformer will result in approximately 17 volts dc when rectified and filtered. A full wave bridge and appropriately sized capacitor followed by a switching buck regulator module is one way to achieve your goal. But, by the time you’re done with sourcing, fitting and mounting the additional parts required, it’s probably easier to purchase a dc output wall wort to power the led’s.

Do you know what current at 12vdc is required for the led’s? Can they be driven with a constant voltage? An led driver is usually a constant current device.

That’s the missing information at present for a more informed answer.

What sort of LEDs are they?

The easiest way is to replace the LED or driver with one which is designed for 12VAC.
