Abstract
The utility model relates to a halogen tungsten lamp without a metal bracket, which is composed of a lamp shell body, a filament, a lamp seat and a lamp tripod; connecting parts are transversally extended respectively inside the lamp shell body at both opposite sides at the upper end of the lamp shell body, and free ends of two connecting parts are jointed each other, a joint part which is used for connecting two connecting parts is arranged on the filament; the connecting parts are taken as a filament bracket, so as to replace traditional metal molybdenum filament as the bracket, so not only the manufacturing cost is greatly reduced, but also the manufacturing technique is simpler, and the defect that taking the metal molybdenum filament as the bracket can influence the service life of the lamps can be avoided, thus having strong practicality.
Description
Technical field
The utility model relates to a kind of illuminating lamp, relates in particular to a kind of tungsten halogen lamp.
Background technology
Existing tungsten halogen lamp mainly comprises bulb shell, be arranged on the filament in the bulb shell, the lamp socket that is positioned at the bulb shell lower end and is fixedly connected with bulb shell, one end and the lamp socket lamp base that expose the other end that is fixedly connected, described filament is electrically connected by molybdenum sheet and the lamp base that is arranged in the lamp socket, bulb shell and lamp socket all are to be made by high temperature resistant and the higher quartz glass of mechanical strength, can not be too thick it be soft thereby the smaller size smaller of tungsten halogen lamp has determined its filament, therefore when being arranged on, it needs stent support in bulb shell, filament in the existing tungsten halogen lamp bulb shell all is to make support by the metal molybdenum filament that sets within it, make the cost that support has not only increased whole tungsten halogen lamp with the metal molybdenum filament, and increased the difficulty of production technology, also there is following defective in they: can produce the possibility of arc discharge, the useful life of reducing bulb between metallic support and the filament; Contain halogen tungsten circulation agent in the blanketing gas that uses in the production and processing this metallic support is had corrosiveness, also can influence the useful life of bulb; The high temperature that produces when bulb is lighted makes metallic support evaporate foreign gas under the high temperature price modification, influences the useful life of bulb equally.
The utility model content
The utility model purpose is exactly that a kind of no metallic support tungsten halogen lamp that reduces production costs and prolong bulb life is provided in order to overcome the deficiencies in the prior art.
In order to reach the foregoing invention purpose, the technical solution of the utility model is: a kind of no metallic support tungsten halogen lamp, comprise bulb shell, be arranged on the filament in the bulb shell, the lamp socket that is positioned at described bulb shell lower end and is fixedly connected with bulb shell, one end and described lamp socket two lamp bases that expose the other end that are fixedly connected, described filament the two poles of the earth are electrically connected by molybdenum sheet and the lamp base that is arranged in the described lamp socket, in described bulb shell cavity, laterally extend a junction respectively in relative both sides, the upper end of described bulb shell, and the free end of described two connecting portions fits, and described filament load is located at the junction of two connecting portions.
Further, the cross section of described connecting portion is circular, and the cross-sectional diameter of connecting portion is from outer extremely interior reducing gradually.
Described connecting portion is arranged with by bulb shell and forms, and is formed with circular recess on corresponding bulb shell.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: owing to laterally extend a junction respectively in the bulb shell cavity in relative both sides, the upper end of bulb shell, and the free end of two connecting portions fits, described filament load is located at the junction of two connecting portions, make filament support by connecting portion like this, thereby replace the conventional metals molybdenum filament to make support, this makes the manufacturing cost of tungsten halogen lamp reduce greatly on the one hand, and make production technology simpler, and overcome the metal molybdenum filament as the defective that influences bulb service life that support brought, have stronger practicality.
Description of drawings
Accompanying drawing 1 is the utility model structural front view;
Accompanying drawing 2 is the end view of the utility model structure;
Wherein: 1, bulb shell; 2, filament; 3, lamp socket; 4, lamp base; 5, molybdenum sheet; 6, connecting portion; 7, circular recess.
Embodiment
Below in conjunction with accompanying drawing the utility model preferred embodiment is elaborated:
Tungsten halogen lamp as depicted in figs. 1 and 2, comprise bulb shell 1, fixedly connected and be positioned at the lamp socket 3 of bulb shell 1 lower end with bulb shell 1, bulb shell 1 is made by quartz glass high temperature resistant and that mechanical strength is higher with lamp socket 3, in bulb shell 1, be provided with filament 2, it is by the tungsten filament coiled, the both ends of filament 2 are stretched in the lamp socket 3, at lamp socket 3 internal fixation two molybdenum sheets 5 are set, and filament 2 is electrically connected by the lamp base 4 that a molybdenum sheet 5 and an end are fixedly installed in the lamp socket 3 respectively.
In the present embodiment, laterally extend a junction 6 respectively in bulb shell 1 cavity in relative both sides, the upper end of bulb shell 1, this connecting portion 6 is made by quartz material, and the free end of two connecting portions 6 fits, and filament 2 loads are located at the junction of two connecting portions 6.
In order to simplify technology, each connecting portion 6 is arranged with by the bulb shell 1 of respective side and forms, like this, on corresponding bulb shell 1, be formed with circular recess 7, and connecting portion 6 flares, promptly its cross section is circular, and the diameter of cross section reduces gradually, and it is simpler that this makes technology, and cost is lower.
