A type of Auto Lamp that used quartz as glass shell and filled with halogen gas gives a very bright light. Principle is inside the halogen bulb such as injection of iodine or bromine, under high temperature, the sublimation of chemistry with halogen tungsten filament, tungsten will be cooled to solidification on tungsten filament, form balanced circle, avoid premature tungsten filament fracture. So halogen bulbs live longer than incandescent bulbs. The supply voltage of halogen lamp is usually divided into ac 220V and dc 12V and 24V. The halogen lamp is made of tungsten, but it is enclosed in a smaller quartz glass shell. Because the glass is very close to the filament, if it's made by normal glass, it will melt very easily. The gas in the glass is composed of different gases. These gases have a very interesting feature. They are combined with tungsten vapor. If the temperature is not high enough, the halogen gas combines with the tungsten vaporization and redeposition of the filament. This cycle makes the filament can last more time. Halogen bulb is hotter than a normal bulb.
Advantages and disadvantages
The halogen lamp is an improvement in the incandescent lamp, which maintains the advantages of the incandescent lamp: simple, low cost, easy to adjust and control brightness, and good color display (Ra=100). At the same time, the halogen lamp overcomes many shortcomings of the incandescent lamp, such as short service life and low luminous efficiency (usually only 6% to 10% can be converted to light energy, and the rest are lost in the form of heat energy).
Halogen lamp: strong penetration and uniform light in rain and snow.
