Abstract
The utility model relates to a voltaic arc tube used for a metal halide lamp, which is provided with a ceramic straight tube with openings at two ends. Both ends of the ceramic straight tube are respectively provided with an airproof ceramic stopper, and an eduction tube is arranged on each airproof ceramic stopper; the airproof ceramic stoppers connected with both ends of the ceramic straight tube are column-shaped shells and are provided with taper inclined planes; each eduction tube is integrated with the corresponding ceramic stopper into a whole; the front end of each airproof ceramic stopper is provided with a vertical head face which can restrain the metal halide in the voltaic arc tube to flow into the sealing part of the eduction tubes and the eduction line of an electrode and effectively prolong the service life of the metal halide lamp. A cavity structure formed after the molding of the ceramic straight tube and the airproof ceramic stoppers accords with the voltaic arc shape requirement of the metal halide lamp, thereby improving the light effect, the color rendering index and the coherence. Both ends of the voltaic arc tube have lowest thermal capacity, so the temperature at both ends can be enhanced full out, the electrode sputtering is reduced, and the service life of the metal halide lamp is effectively prolonged; the voltaic arc tube has reliable sealing, high product security, simple structure, convenient molding, and easy control for the size, and is suitable for batch production.
Description
Technical field
The utility model relates to a kind of metal halide lamp electric arc tube.
Background technology
It is long that metal halide lamp has the light efficiency high life, and the color rendering index advantages of higher is widely used and the station, harbour, and road, the airport, the warehouse, the every field of indoor and outdoor lighting such as market is described as the third generation in the world lighting source.The general adopting quartz glass of conventional metals halide lamp is as its arctube material, but quartzy meeting and the metal halide chemically reactive that charges in the lamp under the lamp working temperature, thereby influence the consistency and the maintenance of metal halide lamp photoelectric properties, limited the use of metal halide lamp and promoted.Because aluminium oxide ceramics at high temperature has better chemical stability, under the working temperature with electric arc tube in metal halide reaction not obvious, thereby the metal halide lamp electric arc tube is worked under higher temperature, light efficiency is higher than quartz metal halide lamp more than 15%, has higher stability, photoelectric parameter is kept better, so the research and development of aluminium oxide ceramics electric arc tube and industrialization are significant to setting up conservation-minded society.
But because the characteristic that aluminium oxide ceramics had, make that the machine-shaping of aluminium oxide ceramics electric arc tube is very difficult, produce for simplifying, existing metal halide lamp ceramic arc tube adopts the column type cavity body structure more, yet this arc tube chamber body structure shape does not meet the requirement of arc shape in the metal halide lamp, can in electric arc tube, form cold junction, thereby the difference that causes the light electrical quantity, and the shortening of metal halide lamp life-span, and the ceramic arc tube of column type cavity body structure that the temperature of metal halide lamp is risen is slower, electrode sputter aggravation.
The utility model content
The purpose of this utility model is to provide a kind of arc tube chamber shape to meet the requirement of arc shape, and metal halide lamp is rapidly heated, and effectively prolongs the metal halide lamp metal halide lamp electric arc tube in useful life.
The technical scheme that realizes the utility model purpose is: the utlity model has the ceramic straight tube of both ends open, ceramic straight tube two ends respectively are provided with a sealing porcelain plug, and each sealing porcelain is provided with extraction tube beyond the Great Wall; The sealing porcelain plug that described ceramic straight tube two ends connect is a cylindrical housings, front opening, and front end face is provided with the circular cone inclined-plane perpendicular to the axis of sealing porcelain plug between sealing porcelain plug front end face and the rear end inwall; Each extraction tube is an integral piece with corresponding sealing porcelain plug; Sealing porcelain plug front end inserts in the ceramic straight tube openend to be rabbeted with ceramic straight tube.
Above-mentioned metal halide lamp is with having chamfering between the sealing porcelain plug rear end outer wall of electric arc tube and the extraction tube outer wall.
The front end face height of the sealing porcelain plug of above-mentioned metal halide lamp usefulness electric arc tube is between 0.2～5 millimeter.
The utlity model has following characteristics:
(1) sealing porcelain plug of the present utility model has the circular cone inclined-plane, helps to improve this position temperature and the formation that suppresses cold junction, improves the stability of metal halide lamp;
(2) sealing porcelain plug front end face of the present utility model is a perpendicular end surface, can suppress sealing place that metal halide in the discharge tube flows to extraction tube and electrode outlet line, effectively prolongs metal halide lamp useful life.
(3) the sealing porcelain plug in the utility model and the junction of extraction tube are provided with chamfering, have improved this place's mechanical strength, alleviate junction stress, have improved Product Safety.
(4) the utility model is simple in structure, and convenient formation, size are easy to control, is suitable for producing in batches.
