Abstract
The utility model relates to a halogen lamp bulb which comprises a bulb casing (4) on which two opposite bulges for pressing filaments are arranged, the filaments (3), molybdenum pieces (5), molybdenum pins (6) and a hollow quartz glass tube (1), wherein the filaments (3) penetrate through the quartz glass tube (1), and are led out from two end openings of the quartz glass tube (1). The filament pins at both ends of each of the filaments (1) are respectively and electrically connected with two molybdenum pieces (5) and two molybdenum pins (6) in sequence. The two opposite bulges (2) are arranged on the inner wall of the bulb casing (4), and are fixedly connected to two end openings or the outer wall of the quartz glass tube (1). The utility model has the advantages of simple structure, easy manufacture, good anti-explosion performance and long service life.
Description
Technical field
The utility model relates to lighting technical field, specifically, relates to a kind of halogen tungsten 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 halogen tungsten 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 halogen tungsten 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 halogen tungsten bulb of long service life.
The technical scheme that realizes above-mentioned purpose is: a kind of halogen tungsten bulb, comprise cell-shell, filament, molybdenum sheet and molybdenum pin, have two projections in opposite directions that compress filament on the cell-shell, also comprise hollow quartz glass tube, filament passes quartz glass tube, and draws from the two-port of quartz glass tube, and the two ends wire foot of filament is electrically connected in proper order with two molybdenum sheets, two molybdenum pin respectively, 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.
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.
