Yes. All you need is a DC wall wart, a 5V power supply and some wire.

A 5V power supply like this would do nicely.

Basically the wall wart draws DC current and the power supply clamps it to 5V and about 500 mA. From there, you just connect the wires to the leds in a parallel fashion (you can use a resistor to limit the current if your leds are small) and you can light it up anytime or all of the time if you want.

So to summarize : Wall wart -> 5V power supply -> Leds

As I am an amature myself, I hope my advice is correct. If I'm wrong feel free to correct me anyone.

Take a look at this web page on information how to wire up the led's:

The resistors are required for current limiting.
