Narrative:

Ten minutes after take off we received 4 chimes from a flight attendant advising us that they had detected some smoke and fumes around row 8. She said she will investigate it more and call us back. In the meantime; I elected to run the 'smoke/fire/fumes' checklist. Within about a minute the flight attendant called us back and informed us that in fact there was smoke and fumes coming from an overhead bin; and it smelled of melted plastic. At that point she was told to keep us updated and that we would declare an emergency and return to [departure airport]. We declared an emergency with ATC and requested vectors back. Requested arff crew and the frequency for them. Advised tower we would stop on the runway. After we stopped; the first officer coordinated with the arff crew while I made a PA to the passengers and flight attendants. I then opened the cockpit door to get a better visualization of the cabin situation. I asked the flight attendants if it was under control and could we just taxi back to the gate promptly. Their response was; 'yes; it's okay; taxi back to the gate.' I told them to brief the passengers that when we get back to the gate that they were to deplane promptly without their luggage; and that rescue crews would be boarding after that. To my knowledge; no injuries were sustained. Maintenance determined it was a light ballast that overheated.
