Narrative:

Passing thru 10000 ft; received a call from back that smoke was coming into the cabin and fire extinguisher was going to be used. We declared an emergency and requested immediate clearance to ZZZ which we received. Wind was calm...requested runway 19L approach which we had in sight. Called to back to see if smoke was still coming into the cabin. Flight attendant stated it was not. Made the decision to pull clear of runway 19L and let fire crew look over aircraft. Fire crew gave all clear. Taxied back to gate where smell of acrid type smoke returned. Passenger left thru door 1L without carryons. Maintenance and fire crew entered aircraft and seemed to think it was a light bulb above fc seats.
