Click here to learn more about the Energy Independence and Security Act of 2007 and how it might affect you. Many incandescent bulbs are scheduled to be phased out of production by 2014.

As a result, the incandescent lamp is widely used both in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting.

They are also compatible with control devices such as dimmers, timers, and photo sensors, and can be used both indoors and outdoors. Incandescent bulbs require no external regulating equipment, have a very low manufacturing cost, and work well on either alternating current or direct current. Because the naked eye cannot perceive ultraviolet light, it is converted to visible light by the phosphor coating.įor more information about how lightbulbs work, contact Pacific Lamp.Diagram showing the major parts of a modern incandescent light bulb. When the lamp is flicked on, electrons are bombarded into the ionized mixture of gases and ultraviolet radiation is created. The tube is layered with a substance made out of phosphorus. The components of a fluorescent lamp include a sealed glass tube containing a mixture of mercury and nonreactive gases, such as neon, xenon, argon and krypton. The emitted lightĪppears yellowish, and a significant portion of energy is lost as heat. The tungsten wire, the filament's temperature reaches around 3,140 to 4,940 degrees Fahrenheit. When a supply of electrical current passes through Or infused with an inert gas that prevents it from burning up. In most households, the two commonly used types of light fixtures are incandescent bulbs and fluorescent lamps.Īn incandescent bulb consists of a tungsten metal filament inside a sealed glass bulb, which is either evacuated

A tungsten filament inside a light bulb can reach temperatures as. An incandescent bulb produces more heat and radiates less Incandescent bulbs typically use a tungsten filament because of tungstens high melting point. The ultraviolet that is produced into visible light.

An incandescent bulb works by using electricity to generate enough heat to make the bulb's filament glowĪnd emit light, while a fluorescent lamp functions by colliding gaseous atoms with electrons and transforming
