Different types of lamp

अपनी भाषा का त्वरित अनुवाद करें

(1) Arc Lamp

Arc LampArc Lamp-: It is discovered by Humphry Davy in between 1800s. These types of lamps are constructed to operated on DC (Direct Current) or AC (Alternating Current) system when it connected in series or any other connection is occurs. The high_intensity light is produced by this carbon vapor which is highly luminous in the arc. These are enclosed in a glass tube under low pressure.


(2) Filament Lamp

Filament lampFilament Lamp-: It contains a thin coil of wire, also known as the coiled coil or filament. Filaments in incandescent light bulbs are made of tungsten. It is heavy heated when an electric current passes through it. For this heat light is produces. When the  resistance of a filament lamp increases then the temperature of filament is also increases.


Gas Discharge Lamp

Gas Discharge Lamp

Gas Discharge Lamp-: Gas discharge lamps are full field by noble gas. The gases in these lamps are ionized in operation and for this gas electric current is passes through it. Electron collide atoms of the gas and the metal.


 Tube Lightfluorescent lamp

What is Tube Light-: The shaped of the fluorescent lamp is termed as tube light. Fluorescent tubes/lamps are filled with mercury vapor.Tube light is a lamp that works on low pressure mercury vapor discharge phenomenon and converts ultra-violate ray into visible ray with the help of phosphor coated inside glass tube. A glow starter or commonly known as starter is used in the tube light circuit to provide an initial current to filaments of the tube light.

What type of material used inside the Tube Light-: (i)Phosphor coated glass bulb (ii)Glass stem (iii) End cap (iv) Electrode shield (v) Inert gases (argon) (vi)Filament coils as electrodes
