An incandescent light works by the emission of light caused by heating the carbon filament. Known as the common household light bulb, they are created in an extremely wide range of sizes, wattages, and voltages.
How Long Have They Been Around?
Incandescent bulbs have been in use for over 100 years and are the original form of electric lighting. Fun fact: There are a number of people who invented prototypes of the light bulb well before Thomas Edison did, even though many believe he created the light bulb. British physicist Joseph Wilson Swan, whose house was the first to be lit by a light bulb, received the first patent for a complete incandescent light bulb with a carbon filament in 1879.
How do they work? An incandescent bulb is made of a glass enclosure surrounding a tungsten filament. When an electric current passes through the filament, heating it to produce light. Small wires embedded in the stem support the filament and/or its lead wires. To keep the filament from evaporating, the glass enclosure contains an inert gas or vacuum.
Incandescent bulbs are very economic, and work well on either alternating current or direct current. These bulbs are compatible with all sorts of devices, such as dimmers, timers, and photo sensors. They can be used in both indoor and outdoor lighting fixtures. They are great for portable lighting fixtures like table and floor lamps, and are easy to replace.
