INCANDESCENT LAMP
A glass enclosure
in which light is produced when a tungsten filament is electrically
heated so that it glows. Much of the energy is converted into heat;
therefore, this class of lamp is a relatively inefficient source of
light. Included in this category are the familiar screw-in light bulbs,
as well as somewhat more efficient lamps, such as tungsten halogen
lamps, reflector or r-lamps, parabolic aluminized reflector (PAR)
lamps, and ellipsoidal reflector (ER) lamps.
An electric lamp in which a filament is heated by an electric current until it emits visible light.
