an electric lamp consisting essentially of a glass or quartz bulb evacuated or filled with an inert gas in which a filament, commonly of tungsten, gives off light when it is heated to incandescence by an electric current.
Generates visible light by heating a filament until it radiates. Incandescent lamps come in standard voltage and low voltage versions. They produce a significant amount of heat, are less energy efficient, and have a significantly shorter life than fluorescent lamps. Incandescent lamps are used liberally in retail and entertainment applications as well as commercial lobbies, conference areas, and theatres.
A lamp that produces light by directing electrical current through a metallic medium. The efficiency of lamps is stated as an efficacy rating (lumens/input wattage). For example, a 100-watt lamp that produces 1,740 lumens has an efficacy of 17.4 lumens per watt. The average incandescent lamp typically falls in the 10-25 lumens per watt range.
A lamp which creates light by heating up a thin filament, usually tungsten wire. Most standard household light bulbs as will as tungsten halogen lamps are incandescent. The color temperature of most incandescent lamps ranges from 1800. Kelvin to about 3800. Kelvin. See Also: Color Temperature Tungsten Halogen Lamp
A light source using the principle of incandescence. When an electric current passes through a filament wire (usually tungsten), the heated wire glows. Filaments of standard incandescent lamps are enclosed in a vacuum or gas-filled bulb. They provide low initial cost, good color rendition and excellent optical control.
lamp in which a current flowing through a thin wire (or filament) heats the filament to such a high temperature that it gives off light; incandescent lights are the most familiar type of light source--for example, typical "light bulbs" are incandescent lamps.
Where the light is created by heating a Tungsten filament. The filament is contained in a glass bulb filled with an inert gas (nitrogen or rare gas) that prevents it from oxidizing, and then delays the vaporization of the filament material. Incandescent lamps are available in actually many forms; the most common are general service lamps with pear-shaped, clear and matt bulbs.
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.
