The halogen gas of iodine or bromine etc., deduction cap are fixed with lamp holder, and lamp panel is equally fixed with lamp holder.Its operation principle is：When filament is tungsten
Silk adstante febre, tungsten atom are moved by backward quartz crust shell wall direction is evaporated, and when close to quartz crust shell wall, tungsten steam is cold
But combined to about 800 DEG C or so and with halogen atom, formation tungsten halide, such as tungsten iodide or tungsten bromide, tungsten halide is to quartz crust
Center continues to move to and is oxidized on filament.Because tungsten halide is a kind of extremely unstable compound, thus it is after heated
Halogen steam and tungsten are resolved into again, and then tungsten deposits on filament again, makes up or compensates the part evaporated, pass through this
Kind regeneration cycle, the service life of filament are able to extend ultimate attainmently（It is more than four times of ordinary incandescent lamp）.
As is known in the industry, because halogen quartz lamp substantially belongs to vacuum device category, thus to the sealing of quartz crust
The requirement of end is very harsh because a pair of molybdenum foil clamps of connection filament and molybdenum rod are in sealing end, due to sealing end by
Symmetrical two valve structures melt binding is formed, thus is accustomed to claiming clamp portion, once and because sealing end goes out in use
Now even micro- vast cracking, a pair of molybdenum foils will be aoxidized and whole quartz bulb is scrapped in advance.Particularly some are big
The bulb of automobile headlamp bulb and the heat dissipating state shortcoming of power, because temperature is high at clamp and cannot get desired radiating effect
Fruit, exacerbate the oxidized degree of molybdenum foil that ftractureed at clamp.Therefore how effectively to solve the problems, such as that molybdenum foil is oxidized for a long time
Industry is suffered from, technical scheme described below is caused under this background.
