By doing this, you are applying 5v to the output of the Arduino's on board voltage regulator. Depending on the regulator model, this pratice could damage it, but in most cases I believe it will not. Assuming the regulator on the arduino board is "ok" with this, the onlyoncernonly concern left would be itif the AC adapter can supply the current you need.

Another approach would be connecting a 9v9V adapter to the Arduino power input and use a external regulator to down the voltage to 5V only for supplying the LED's.
