Question

What are the advantages of using Discharge lamps instead of Incandescent lamps?

Answer 1

Hint: In order to answer this question we need to understand discharge lamps and Incandescent lamps.
A discharge lamp or a gas discharge lamp is a lamp in which an generated artificial light source is used instead of regular one, in this lamp, an ionized gas is captured inside chamber where we send an electric discharge causing plasma (fourth state of matter) to generate inside it, when plasma heat up it glows and emits light which then by using filters spread outside lamp as beautiful colors of light.
In Incandescent lamps, a filament is used inside the vacuum chamber bulb. When electric current passes through it, it generates heat which glows as light.

Complete answer:
Advantages of discharge lamps over incandescent lamps:
Less consumption of electricity: Discharge lamps consume less electricity in comparison to incandescent lamps because in later lamps to spread light continuous electric current is required while in former lamps electricity requires only to create plasma, once created it no longer needs electricity.

More life span: Discharge lamps have more life then incandescent one because incandescent use physical filament which after sometime get ruined due to continuous heating process.

More light: Discharge lamps use plasma to generate light which is much more powerful than any physical filament, plasma energy is used to conduct nuclear fusion, so you can think how powerful it is. Other advantages include, no shadow formation, less heat consumption etc.

Note: Although discharge lamps have many advantages but it had a disadvantage also that plasma has immense energy, if energy is not controlled then it could be hazardous in nature and can prove to be havoc but companies took care of energy by using other components in bulb.
