Label A and B in the given diagram. What is the diagram of ?
1 Answer
The given diagram is of a fluorescent lamp.
A: Mercury vapor and B is fluorescent powder.
CFLs work much like standard fluorescent lamps. They consist of two parts: a gas-filled tube, and a magnetic or electronic ballast. The gas in the tube glows with ultraviolet light when electricity from the ballast flows through it.Fluorescent lamps work by ionizing mercury vapor in a glass tube. This causes electrons in the gas to emit photons at UV frequencies. The UV light is converted into standard visible light using a phosphor coating on the inside of the tube.A fluorescent bulb consists of a glass tube with a phosphorous coating, a small amount of inert gas (usually argon or krypton), mercury, and a set of electrodes. Contact points on the outside of the tube carry electricity into the bulb.
Fluorescent starters or glow starters are used to help fluorescent tubes and lamps ignite in the initial starting stage of their operation. Simply put, fluorescent starters are a timed switch. The switch opens and closes until the fluorescent tube 'strikes' and lights-up.LED or fluorescent tube lighting is the better choice because it lasts about 40,000 hours longer in testing, is more energy efficient, will save you more money, and will leave less impact on the environment.
