lamps Definition

any of various devices for producing light or sometimes heat: such as

a vessel with a wick for burning an inflammable liquid (such as oil) to produce light

a glass bulb or tube that emits light produced by electricity (such as an incandescent light bulb or fluorescent lamp)

an electric lamp that produces light by an arc made when a current passes between two incandescent electrodes surrounded by gas —called also arc light

an electric lamp in which an enclosed gas or vapor glows or causes a phosphor coating on the lamp's inner surface to glow

a tall lamp that stands on the floor

a usually tubular electric lamp having a coating of fluorescent material on its inner surface and containing mercury vapor whose bombardment by electrons from the cathode provides ultraviolet light which causes the material to emit visible light

a gas-discharge electric lamp in which most of the light proceeds from the glow of the gas near the cathode

light bulb

a decorative lamp constructed of a transparent glass container filled with liquid and wax that is heated by an incandescent bulb which melts the wax and causes it to form random moving shapes within the liquid

an electric lamp: such as

one in which a filament gives off light when heated to incandescence by an electric current —called also incandescent, incandescent lamp

fluorescent lamp

an electric lamp in which the discharge takes place through mercury vapor —called also mercury lamp
