What is a Halogen Bulb?
A halogen bulb is a type of incandescent light bulb, introduced in 1958. The halogen bulb is capable of burning much more brightly than conventional light bulbs, and it is a popular choice for headlights and other applications for which very bright light is needed. In addition to burning more brightly, halogen bulbs are also more efficient and have a longer life expectancy than conventional light bulbs. The halogen bulb uses a design very similar to that of conventional light bulbs, consisting of a tungsten filament enclosed in another material. The halogen bulb uses quartz instead of glass, however, allowing the bulb to be much smaller because quartz can withstand higher temperatures than glass and therefore may be positioned much closer to the filament. In addition, halogen bulbs use halogen gases, instead of argon or nitrogen, two gases commonly used in conventional light bulbs. A light bulb works by applying electricity to the tungsten filament, which heats up and puts out light. H
Halogen is a type of incandescent lamp. It has a tungsten filament just like a regular incandescent that you may use in your home, however the bulb is filled with halogen gas. When an incandescent lamp (one which produces light by heating a tungsten filament) operates, tungsten from the filament is evaporated into the gas of the bulb and deposited on the glass wall. The bulb “burns out” when enough tungsten has evaporated from the filament so that electricity can no longer be conducted across it. The halogen gas in a halogen lamp carries the evaporated tungsten particles back to the filament and re-deposits them. This gives the lamp a longer life than regular A-line incandescent lamps and provides for a cleaner bulb wall for light to shine through.
