A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.

A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs.
Since their introduction as a commercial product in 1939, many different types of fluorescent lamp have been introduced. Systematic nomenclature identifies mass-market lamps as to overall shape, power rating, length, color, and other electrical and illuminating characteristics.
Świetlówka kompaktowa, kompaktowa lampa fluorescencyjna (CFL ang. Compact fluorescent lamp), znana też w handlu jako świetlówka energooszczędna – jest to rodzaj lampy fluorescencyjnej (świetlówki) o kształcie zapewniającym małe wymiary gabarytowe. Świetlówki takie mają najczęściej bańkę w kształcie litery „U” (często ...
Świetlówka, lampa fluorescencyjna [1] – lampa wyładowcza, w której światło emitowane jest przez luminofor wzbudzony przez promieniowanie ultrafioletowe powstałe wskutek wyładowania jarzeniowego w rurze wypełnionej gazem. Historia. [edytuj | edytuj kod] Prace nad zbudowaniem lampy zaczęły się w latach 30. XX wieku.
A fluorescent lamp is a type of electric light (lamp) that uses ultraviolet emitted by mercury vapor to excite a phosphor, which emits visible light. There are two general types, traditional fluorescent and compact fluorescent.
13 maj 2023 · The fluorescent light bulb creates light by sending electricity through a gas. This produces visible light, but also some ultraviolet light, which is invisible to the human eye. To make the ultraviolet visible, the inside of a fluorescent light bulb is coated in a substance that absorbs ultraviolet and changes it to visible light.
