This causes an electron to jump up to an orbital with a higher energy. A phosphor on the walls of the tube absorbs the ultraviolet light. An electric current is applied to mercury vapor inside the tube, causing it to emit ultraviolet (UV) light. How does a fluorescent light bulb work for kids? What’s the difference between a compact fluorescent light bulb and a fluorescent bulb? In addition, most compact fluorescent lamps have an “integral” ballast that is built into the light bulb, whereas most fluorescent tubes require a separate ballast independent of the bulb. How do fluorescent and compact fluorescent lamps differ? 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. 9 How are ballasts added to compact fluorescent lamps?Ī fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light.8 How are compact fluorescent lamps different from incandescent bulbs?.7 How does the light in a fluorescent lamp work?.6 How do fluorescent light bulbs work simple?.5 What is the difference between other lamps and fluorescent lamp?.4 How fluorescent and compact fluorescent bulbs work describe how their operations and their spectra differ from those of incandescent light bulbs?.3 How does a fluorescent light bulb work for kids?. 2 How do fluorescent and compact fluorescent lamps differ?.
