Description

Based on halogen bulb

Technical field

The utility model relates to lighting technical field, specifically, relates to a kind of based on halogen bulb, is used for the illumination of indoor and outdoor.

Background technology

What know altogether at present, is to be made of cell-shell, filament, the bead support that has tungsten and molybdenum material, two molybdenum sheets, two molybdenum pin etc. in the structure of the based on halogen bulb of civil power work directly.Filament is fixed by a bead stent support that has tungsten and molybdenum material, in the support both sides or on support and position that molybdenum sheet is connected, uses fuse to connect then, draws from the cell-shell other end through molybdenum sheet and molybdenum pin respectively again.Because close together between the filament, and under the state of high pressure 220V, work again, product is being shaken or is rocking and when the life-span be about to stop, be easy to occur jumping electrical phenomena, and the electric arc that produces when filament blow can be shifted to the seal wire root rapidly especially, if this moment, electric arc can not extinguish rapidly, arc energy is the seal wire scorification, even seal wire is burnt till metal vapors, because seal wire is thicker, more metal vapors can make the cell-shell internal gas pressure sharply increase, thereby causes the bulb blast.Have the bead support of tungsten and molybdenum material simultaneously owing to use the some stent support filaments that are fixed on the bead, distance between its filament is very near, the hank knotting phenomenon will appear, make filament impaired, when energising is used, will occur not working or when jumping electricity, can cause the bulb explosion phenomenon, this shows that there is wretched insufficiency in the security performance of the based on halogen bulb of this kind structure.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to manufacture, explosion-proof performance is good, the based on halogen bulb of long service life.

The technical scheme that realizes above-mentioned purpose is: a kind of based on halogen bulb, comprise cell-shell, filament, molybdenum sheet and molybdenum pin, also comprise hollow quartz glass tube, filament passes quartz glass tube, and draw from the two-port of quartz glass tube, the two ends wire foot of filament is electrically connected in proper order with two molybdenum sheets, two molybdenum pin respectively, has two projections in opposite directions on the inwall of cell-shell, and the two-port or the outer wall of this projection and quartz glass tube are affixed.

After adopting technique scheme, based on halogen bulb is only made support with a hollow quartz glass tube, filament passes quartz glass tube, and draw from the two-port of quartz glass tube, thereby the direct filament supports of quartz glass tube, need not to use the scaffolding thread of fuse and tungsten and molybdenum material, the two ends wire foot of filament can directly be connected with molybdenum sheet, make the very simple and science of bulb structure, again owing to do not adopt tungsten and molybdenum material to come supporting bracket in the bulb, distance between the filament can be drawn back a bit relatively, the filament damaged phenomenon of having avoided hank knotting to cause, the also bulb that just can not take place to cause because of filament the is impaired phenomenon that do not work, also avoided simultaneously the gas metallic molecule that circulation time produced in bulb to change, stopped to jump electric caused bulb explosion phenomenon, thereby prolonged the useful life of bulb, improved the fail safe of using greatly.In addition, have two projections in opposite directions on the inwall of cell-shell, the two-port or the outer wall of this projection and quartz glass tube are affixed, make the fixing very convenient of quartz glass tube, have simplified manufacturing process.
