Definition of fluorescent tube lamp in English English dictionary
fluorescent lamp: a gas-discharge lamp that uses fluorescence to produce visible light
fluorescent lamp: glass tube coated on the inside with a fluorescent substance that gives off light
fluorescent lamp: lamp consisting of a tube coated on the inside with a fluorescent material; mercury vapor in the tube emits ultraviolet radiation that is converted to visible radiation by the fluorescent material
fluorescent lamp: n. A lamp that produces visible light by fluorescence, especially a glass tube whose inner wall is coated with a material that fluoresces when an electrical current causes a vapor within the tube to discharge electrons. Type of electric discharge lamp consisting of a glass tube filled with a mixture of argon and mercury vapor. A current of electricity causes the vapor to produce ultraviolet radiation that, in turn, excites a phosphor coating on the inside of the tube, causing it to fluoresce, or reradiate the energy as visible light. Fluorescent lamps are cooler and more efficient than incandescent lamps. They are commonly installed with diffusers as part of a suspended ceiling system. See also fluorescence
