Webincandescent lamp, any of various devices that produce light by heating a suitable material to a high temperature. When any solid or gas is heated, commonly by combustion or resistance to an electric current, it gives off light of a colour (spectral balance) characteristic of the material. With the development of electric power early in the 19th century, the only … WebThese lamps are used to generate light from an incandescent filament that operates in an inert gas ambiance. The addition of the inert gas will suppress the evaporation of the …
WebIncandescent light bulbs are commonly filled with a mixture of argon and nitrogen; but the “halogen” variant will contain some bromine or chlorine to react with evaporated tungsten and return it to the filament. Fluorescent tubes will contain mercury gas; when an electric current is run through such gas, the gas glows in a blue-green color and i WebSep 23, 2024 · In a normal incandescent lamp, the filament is made of tungsten metal and surrounded by a nonreactive (“inert”) gas such as argon. The gas is there to make the …
