That's from Phillips, I can't remember the what they call it... ' AmbiLight' possibly. They also make a stand alone LED lighting strip, but it's pricey for what it is. It's not in TVs badges as Phillips sold in the USA - the name is licenced out there.
There are also instructions on Instructables for making a DIY version, probably involving an Arduino. The tricky bit is deciding the HDMI signal (through IIRC the SD part of the signal shouldn't be encrypted).
