Halogen Bulb
Automobile halogen bulbs contain halogen gases such as iodine or bromine. Under high temperature, the sublimated tungsten wire chemically reacts with halogen, and the light emitted is yellow, showing a warm light color and relatively dark.
Product Introduction
Overview
Quick details
Automobile halogen bulbs contain halogen gases such as iodine or bromine. Under high temperature, the sublimated tungsten wire chemically reacts with halogen, and the light emitted is yellow, showing a warm light color and relatively dark. Halogen foam is mainly made of quartz and stainless iron.
Halogen lamp is an improvement of incandescent lamp, it retains the advantages of incandescent lamp: simple, low cost, easy to adjust and control brightness, good color rendering (Ra=100). Meanwhile, halogen lamps overcome many disadvantages of incandescent lamps, such as short service life and low luminous efficiency.
Halogen lamps are made of tungsten wire, but are encased in a smaller quartz glass shell. Because the glass shell is so close to the filament, it will melt easily if it is made of glass. The gas inside the glass shell is composed of different gases to form the halogen lamp group. These gases have a very interesting property: they combine with tungsten vapors. If the temperature is not high enough, the tungsten atoms bound to the halogen gas evaporate and redeposit on the filament. This cycle makes the filament last for a long time. Plus, it can run hot filaments, which means you get more light energy. You're still getting a lot of heat, but because the quartz shell is so close to the filament, it's hotter than a normal bulb.
