Incandescent bulbs provide the light by a process known as Incandescence. Incandescent bulbs have a thin tungsten filament. When the electric current is passed through it, the filament generates lots of heat that results in visible light. Incandescence bulbs are the most used bulb in the world and, though the newer technologies coming everyday are vastly replacing these types of bulbs, they still dominate the market due to their ease of use and familiar feel they provide to the user.
Incandescent bulbs are not energy efficient bulbs and they waste 80% of the energy while generating the light. That way, they consume lots of energy and result in less light. Also, they have a very short life and People need to change the bulb often depending on the times they are used. Also, they provide yellowish color light that most people dislike. They get very hot when lit so great care should be taken to avoid fire hazards. It must be ensured that no flammable object is near to the bulb and more importantly above the bulb as heat moves in an upward direction. Also these kinds of bulbs should not be insulated as they heat up easily and can burn out if heat is accumulated inside.
Incandescent Light Bulbs vs. Fluorescent Light Bulbs
Fluorescent and Compact Fluorescent bulbs are more energy efficient than Standard Incandescent bulbs. Although they are a bit expensive the initial higher cost can be compensated with the energy saving that is provided by Fluorescent light. Not only do Fluorescent bulbs consume less energy, but they also last longer meaning that the user need not change the bulb often.
They also provide the White cooler light. They generate relatively little heat and their surface does not get as hot as an Incandescent bulb. As Incandescent bulbs get very hot, Proper precautions should be taken to avoid Fires.
Gasses in Incandescent Light Bulbs
Incandescent bulbs have a housing of glass to avoid oxygen inside the bulb. As the filament is flammable , it would burn up if there wais oxygen present inside the glass. But Also, Tungsten filament won't work if there is no gas inside it. Basically all Incandescent bulbs work with a small amount of nitrogen and argon gases inside them , there are some bulbs available in the market which work with a vacuum inside them.
Tungsten filament cannot burn up in the presence of Argon and nitrogen gas even if it is flammable as Argon and nitrogen gasses are chemically inert. Some premium and expensive bulbs also consists of krypton gas inside them as krypton is also static and a poor conductor of heat. But as Krypton is highly expensive and a rare element , it is not used that frequently and is often avoided or used in conjunction with nitrogen gas.
The spectrum of Incandescent Light Bulbs Physics
All incandescent bulbs function in a similar manner: Electric Current is passed through a tungsten filament that causes resistance to the electricity. This causes the tungsten filament to heat up to an extremely high temperature. According to the basic law of physics, Objects emit electromagnetic waves with a frequency determined by their temperature. The electromagnetic waves result in visible light at the enormously high temperature of the tungsten filament.
Automotive Incandescent Light Bulbs
All current popular bicycle lighting systems use incandescent bulbs. The majority of these including NiteRider, VistaLite, Night Sun, Turbo Cat, and CatEye, BLT products make use of a variation of incandescent bulb known as halogen bulbs. Other Products like WJ-C3054, WJ-C3034, and WJ-C3035 Automotive Incandescent Lamps with various Colors are also available on the market.
