Electric filament lamps are light sources containing a solid body, brought to a high temperature. The emitting body is generally in the form of a coil or coiled-coil and is known as a filament. Light sources incorporating such filaments are often referred to as incandescent lamps or halogen lamps. Incandescent lamps generate light by passing an electric current through a thin filament wire, usually of tungsten. Light bulbs found in lamps and fixtures around the house are generally incandescent. They are like carbon lamps, standard tungsten lamps etc.
Tungsten halogens are used for studio floodlighting. Line filament lamps are ideal for applications in edge and backlight led displays, emergency display systems, scanners and other specialty illuminations. Miniature filament lamps are used in miniature equipment and circuits. Tungsten filament lamps have a wide rage of technical and commercial applications. They came with incandescent, gas-filled and halogen lamp features.
