Narrative:

On climb out from atl to fay at 10000 ft on a downwind departure vector, the flight attendant called the cockpit to report an excessive amount of smoke coming from an overhead bin. At that point both the first officer and myself smelled a burning odor. At that point I decided to return to atl. We declared an emergency and told them of our wishes to return to atl with smoke in the cabin. We complied with all company procedures for smoke and an emergency descent. Due to the use of the oxygen masks communications between the first officer, myself and atl were difficult. Upon landing I called the flight attendants to get an update on the smoke in the cabin. There was no smoke in the cockpit and the odor was very faint. They reported that the smoke had stopped and I decided not to evacuate/evacuation the aircraft and just taxi to the gate with the emergency vehicles following. Maintenance reported that a passenger reading light transformer had shorted out and burned the surrounding plastic.
