fluorescent lamp

1. (Electrical Engineering) a type of lamp in which an electrical gas discharge is maintained in a tube with a thin layer of phosphor on its inside surface. The gas, which is often mercury vapour, emits ultraviolet radiation causing the phosphor to fluoresce
2. (Electrical Engineering) a type of lamp in which an electrical discharge is maintained in a tube containing a gas such as neon, mercury vapour, or sodium vapour at low pressure. Gas atoms in the discharge are struck by electrons and fluoresce

fluorescent lamp

fluo·res·cent lamp

A lamp that produces light by exciting the atoms of a mixture of argon gas and mercury vapor with electric current. Ultraviolet rays produced by the excited atoms strike a phosphor coating on the interior surface of the bulb, causing it to emit visible light. Fluorescent lamps are much more efficient than incandescent lamps because the excited atoms give off little of their energy as heat. Compare incandescent lamp.
