Halogen Work
how does a halogen bulb work?
A halogen bulb is an incandescent lamp that burns hotter and is slightly more efficient, they can produce more light because of this; however they are still energy hogs.
The titanium filament is stored in a small tube that is made out of quartz (or very strong glass) and filled with a halogen gas. The halogen gases are some of the most reactive and energetic elements on the periodic table of elements. When lit its core is burning and constantly destroying and rebuilding itself. They need high operating temperatures to do this
Halogen bulbs can also be turned into infra red lights because of the high temperatures they produce and work at.
Halogen bulbs can create UV light and can even give you a sunburn, but most are shielded against that. However, due to its high operating temperatures if something like oil secreted by a human gets on the bulb the heat rate is changed and the bulb can shatter. Or it can cause the quartz to weaken and leak which then puts the light out.
According to Wikipedia: http://en.wikipedia.org/wiki/Halogen_lamphttp://en.wikipedia.org/wiki/Halogen_lamp
“A halogen lamp also called tungsten-halogen lamp, the quartz-halogen lamp or the quartz-iodine lamp is an incandescent lamp wherein a tungsten filament is sealed into a small transparent envelope filled with a halogen gas such as iodine or bromine. The halogen lamp can operate its filament at a higher temperature than in a standard vacuum or inert-gas filled lamp, without loss of operating life. This gives it a slightly higher efficiency than standard incandescent lamps…
A tungsten-halogen lamp creates an equilibrium reaction in which the tungsten that evaporates when giving off light is preferentially re-deposited at the hot-spots, preventing the early failure of the lamp. This chemical transport reaction is based on WO2I2 or WO2Br2 formation at elevated temperatures and its decomposition at high temperatures at the tungsten filament. This also allows halogen lamps to be run at higher temperatures which would cause unacceptably short lamp lifetimes in ordinary incandescent lamps, allowing for higher luminous efficacy, apparent brightness, and whiter color temperature. Because the lamp must be very hot to prevent crystalistaion of WO2I2 or WO2Br2 at the glass surface, the halogen lamp’s envelope must be made of hard glass or fused quartz, instead of ordinary soft glass which would soften and flow too much at these temperatures…
A typical halogen lamp is designed to run for about 2000 hours, twice as long as a typical incandescent lamp…
A further development that has added to halogen lamp efficacy is an infrared-reflective coating (IRC). The quartz envelope is coated with a multi-layered dichroic coating which allows visible light to be emitted while reflecting a portion of the infrared radiation back onto the filament…
Because the halogen lamp operates at very high temperatures, it can pose fire and burn hazards. Additionally, it is possible to get a sunburn and cancer from excess exposure to the UV emitted by an undoped quartz halogen lamp. To mitigate the negative effects of unintentional UV exposure, and to contain hot bulb fragments in the event of explosive bulb failure, manufacturers of lamps intended for general-purpose usage usually install UV-absorbing glass filters over or around the bulb. Alternatively, they may add a coating of UV inhibitors on the bulb envelope that effectively filters UV radiation. When this is done correctly, a halogen lamp with UV inhibitors will produce less UV than its standard incandescent counterpart.”
