What is a halogen tube?

Halogen (halogen lamp) is part of the filling gas containing a halogen element or a halide of a pneumatic incandescent lamps. In the ordinary incandescent lamp, the filament of the high temperature caused evaporation of tungsten evaporated tungsten carbide inserts deposited on the envelope, the lamp bulb blackening phenomenon generated. In 1959, the invention of halogen, halogen cycle using the principle of eliminating the black phenomenon.
Halogen cycle process is this: in the appropriate temperature conditions, tungsten evaporates from the filament in the area of ??cell wall material react with a halogen, a halogen to form volatile compounds. As the bubble wall temperature is high enough (250 o C), gaseous halogen compounds, halogen compounds when spread to the area around the hotter filament and tungsten halogen Shiyou differentiation. Released to return to the tungsten filament, and continue to participate in the halogen cycle. Fluorine, chlorine, bromine, iodine, can produce a variety of tungsten halogen regenerative cycle. The main difference between them is the desired temperature cycling reaction occurs along with other substances within the lamp with varying degrees of action now mass production of various bromine tungsten lamp and pad tungsten lights, some lights are also part of the use chlorine as a loop agent. In order to make the resulting halide lamp wall in a gaseous state, halogen wall temperature is much higher than ordinary incandescent lamp. Accordingly, tungsten halogen bulb sizes will be much smaller, you must use high-temperature quartz glass or hard glass. As bulb size, high strength, light allowed on the high pressure, high temperature combined, the operating pressure within the lamp is much higher than ordinary light bulb inflator. Since the evaporation of tungsten halogen being more potent inhibition, while halogen cycle eliminates the bubble shell black, filament temperature and luminous efficiency can be greatly improved, and the lamp life can be extended accordingly. Divided into the main voltage halogen halogen (220V-240V direct access to power) and low-voltage halogen lamps (to be equipped with the appropriate adapter) are two low-voltage halogen lamps have a relatively longer life, safety performance lamps advantages. Choose halogen tips: color temperature of light, life, security, and whether filters to remove ultraviolet light.
