I came across a very nice article at tinkerlog.com  explaining why you need to use a current limiting resistor to power your leds. They write:

In this post I will try to show, why it’s a good idea to use a current limiting resistor for an LED. And when it’s safe to drive the LED without any resistor.

If you read about LEDs, you will notice that everyone tells you, that you need a current limiting resistor. But mostly they do not tell you why.
