INCANDESCENT LAMPS

An incandescent lamp produces visible light by heating a filament to a very high temperature (+500°), through an electric current flow. Tungsten is used in the making of the filament because it combines the properties of high melting point and low rate of evaporation at extremely high temperatures. The components of an incandescent lamp are:

• The filament, made of Tungsten.
• A mixture of inert gases at low pressure. The gas slows down the evaporation of the filament and increases the lamp efficacy.
• Glass bulb, the glass envelop that encloses the Tungsten filament and seals the mixture of inert gases in the bulb.
• The base, usually made of brass or aluminum, which connects the bulb to the electric current.
