Abstract
The utility model relates to a double-end halogen-tungsten lamp which comprises a lamp tube (4), filaments (5) sealed in the lamp tube (4), and porcelain heads (1) on both ends of the lamp tube (4), wherein electrodes (7) are arranged in the porcelain heads (1), and both ends of each of the filaments (5) are connected with molybdenum pieces (6) connected with the electrodes (7) through conducting wires. The utility model is characterized in that the utility model also comprises two or more hollow quartz glass tubes (2). The filaments (5) penetrate through the quartz glass tubes (2), and are led out from two end openings of each quartz glass tube (2). Two opposite bulges (3) are arranged on the inner wall of the lamp tube (4) corresponding to the quartz glass tubes (2), and are respectively and fixedly connected to the outer walls of the quartz glass tubes (2). The utility model has the advantages of simple structure, easy manufacture, good anti-explosion performance and long service life, and is a product for replacing the existing double-end halogen-tungsten lamp.
Description
Technical field
The utility model relates to lighting technical field, specifically, relates to a kind of double end tungsten halogen lamp, is used for the illumination of indoor and outdoor.
Background technology
At present, known double end tungsten halogen lamp comprises fluorescent tube, be enclosed in the filament in the fluorescent tube and the porcelain head of lamp tube ends, has electrode in the porcelain head, the two ends of filament are connected with molybdenum sheet, molybdenum sheet is connected with electrode by lead, the spiral position of filament is by the tungsten stent support of a plurality of annulars, the shortcoming of this structure is a close together between the filament of spiral position, 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, the special electric arc that produces when filament blow can be shifted to the seal wire root rapidly, 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, thereby there is wretched insufficiency in its fail safe.
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 double end tungsten halogen lamp of long service life.
The technical scheme that realizes above-mentioned purpose is: a kind of double end tungsten halogen lamp, comprise fluorescent tube, be enclosed in the filament in the fluorescent tube and the porcelain head of lamp tube ends, has electrode in the porcelain head, the two ends of filament are connected with molybdenum sheet, molybdenum sheet is connected with electrode by lead, also comprise two or more hollow quartz glass tubes, filament passes each quartz glass tube, and draw from the two-port of each quartz glass tube, all have two projections in opposite directions corresponding to each quartz glass tube place on the inwall of fluorescent tube, this projection is affixed with the outer wall of each quartz glass tube respectively.
After adopting technique scheme, double end tungsten halogen lamp is only made support with a plurality of hollow quartz glass tubes, 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, make the very simple and science of bulb structure, simultaneously, the straight line position of quartz glass tube filament supports is separated the spiral position of filament, can reduce the probability of hank knotting greatly, substantially stop the filament damaged phenomenon that hank knotting causes, improve the explosion-proof performance of tungsten halogen lamp effectively, thereby prolonged the useful life of tungsten halogen lamp.In addition, all have two projections in opposite directions corresponding to each quartz glass tube place on the inwall of fluorescent tube, the outer wall of this projection and each quartz glass tube is affixed, makes the fixing very convenient of quartz glass tube, has simplified manufacturing process.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, 2, a kind of double end tungsten halogen lamp, comprise fluorescent tube 4, be enclosed in the filament 5 in the fluorescent tube 4 and the porcelain head 1 at fluorescent tube 4 two ends, has electrode 7 in the porcelain head 1, the two ends of filament 5 are connected with molybdenum sheet 6, molybdenum sheet 6 is connected with electrode 7 by lead, also comprise three hollow quartz glass tubes 2, filament 5 passes each quartz glass tube 2, and draw from the two-port of each quartz glass tube 2, all have two projections 3 in opposite directions corresponding to each quartz glass tube 2 place on the inwall of fluorescent tube 4, this projection 3 is affixed with the outer wall of each quartz glass tube 2 respectively.
The number of quartz glass tube 2 both can adopt three, also can adopt two or three above numbers, decided according to user's needs.
Hollow quartz glass tube of the present utility model 2 is cylindrical, and it is convenient that this structure manufactures the rate of exchange, can save cost.Can certainly adopt square tube, also belong to protection range of the present utility model.
