These electrodes are made of coiled tungsten filament coated with an electron emitting material There are two main parts in a CFL: the gas‐filled tube and the magnetic or electronic ballast. Wear gloves if picking up broken fluorescent lamp fragments The fluorescent lamp (Fig(a) and Fig(b)) generally consists of a long glass tube (G) with an electrode at each end (Eand E 2). By using LED Fluorescent Tube fluorescent lamps, a luminaire using a fluorescent lamp must contain a ballast. An electrical current from the ballast flows through the gas (mercury vapour), Missing: function Aaron Lee. Fluorescent lamps produce visible white light by a two-stage process. First, a charge is induced on the cathode and an electrical current passes through the arc tube Fluorescent Lamps Question: A fluorescent lamp tube is coated with a white powder on its inside surface. The tube is internally coated with a fluorescent powder and contains a small amount ofSee more Parts There are two main parts in a CFL: the gas‐filled tube and the magnetic or electronic ballast. First, a charge is induced on the cathode and an electrical current passes through the arc tube. It is common for indoor LED fluorescent lamp applications utilize betweentolamps per fixture. If that powder were not there, would the lamp appear brighter, applications of fluorescent lighting. Special dimming ballasts and dimming controls are required. As the electric current passes through the gas inside the tube, collisions between moving electrons and ionized mercury atoms produce UV radiation Parts and Function of a Fluorescent LampFree download as Powerpoint Presentation.ppt /.pptx), PDF File.pdf), Text File.txt) or view presentation slides online The ultraviolet light then excites a phosphor coating on the inside of the tube Fluorescent lamps produce visible white light by a two-stage process. Controls: Most can be dimmed but at a higher cost than dimming incandescent lamps. An electrical current from the ballast flows through the gas (mercury vapour), causing it to emit ultraviolet light. The fluorescent lamp (Fig(a) and Fig(b)) generally consists of a long glass tube (G) with an electrode at each end (E1 and E2). These electrodes are made of coiled tungsten filament coated with an electron emitting material. Cautions: Fluorescent lamps contain a small amount of mercury.
