Abstract

The utility model relates to an inorganic non-metallic material and a ceramic tube for light source illumination, in particular to a ceramic tube for metal halide lamp, which comprises two bulkheads. Each bulkhead is an integral structure composed of a tail tube and a ceramic cap on one end of the tail tube. The ceramic cap, which is transitionally connected with the tail tube by an arc type tube on the ceramic cap, is composed of the arc type tube and a column type, which are connected with each other. The ceramic cap of the two bulkheads is an insetting installation structure, which is sintered as a whole to form a ceramic tube of the metal halide lamp. The utility model is provided with rationally designed structure, simplicity and practicality. The semi-transparent alumina ceramic tube, manufactured in accordance with the utility model, is applicable to the manufacturing of 35W-400W metal halide lamp.

Description

A kind of metal halide lamp earthenware

Technical field

The utility model relates to Inorganic Non-metallic Materials and light illumination earthenware, is specially a kind of metal halide lamp earthenware.

Background technology

Metal halide lamp (Metal halogen lamp) is one of state-of-the-art energy-conserving light source in the world today, and advantages such as it has high light efficiency, the life-span is long, color rendering good, compact conformation are widely used in the illumination of indoor and outdoors such as airport, harbour, road, market, hotel.At present, domestic Metal halogen lamp mostly adopting quartz glass material is made, because the luminescent substance of Metal halogen lamp mainly is a rare earth metal, and meeting and quartz glass chemically reactive under the ignition temperature of lamp.Although this reaction is more slowly, burning-point is after a period of time, and therefore its luminescent substance still can cause the photochromic output of lamp to drift about in time because of above-mentioned chemical reaction loses, and also can cause photochromic consistency poor simultaneously.Because the seepage of metal ion also can influence the raising of light efficiency of lamp and the reduction in useful life.In addition, there is comparatively complicated problems of structure in the shell (earthenware) of halide lamp mostly, thereby brings the trouble of complex manufacturing technology.

The utility model content

The purpose of this utility model is to provide a kind of metal halide lamp earthenware, this earthenware reasonable in design, simple and practical.

The technical solution of the utility model is:

A kind of metal halide lamp earthenware, this earthenware comprises two plugs, each plug is the integrative-structure that tail pipe and the ceramic cap that is arranged at tail pipe one end constitute, ceramic cap is that camber pipe and column type pipe connect and compose, ceramic cap is connected with the tail pipe transition by the camber pipe on it, one end opening of camber pipe is communicated with tail pipe, and the other end opening of camber pipe is communicated with the column type pipe, and the ceramic cap of two plugs is a plug-in mounting structure.

The ceramic cap of described plug-in mounting structure is by the sintering sealing-in.

The beneficial effects of the utility model are:

1, the utility model metal halide lamp is the tail pipe that is used for the extraction electrode lead with two plug one ends of earthenware, and the other end is a ceramic cap, and two plugs are by sintering behind the ceramic cap plug-in mounting, and it is simple in structure, practical; Simultaneously, by the camber tube transitions, make its mechanical strength design more reasonable between ceramic cap and the tail pipe, be more conducive to discharge lamp cold and hot stress in the course of the work.

2, the utility model can adopt aluminium oxide ceramics to replace quartz glass, has improved chemical stability, has slowed down the reaction of electric arc tube and metal halogen gas, prevents the seepage of golden halogen gas, has improved the life-span and the photochromic drift that prevents lamp of lamp.

3, the utility model is simple in structure, is convenient to make, and dimensional uniformity is good, the control of easier standardization of the production of translucent alumina and size, and the stability of maintenance inner chamber body volume, the raising Metal halogen lamp is photochromic, the stability of performance.

4, the utility model moulding, firing process are simple, are convenient to produce.

5, the utility model adopt the translucent alumina ceramics pipe have acidproof, alkaline-resisting, chemical stability is good, translucent alumina ceramics is more high temperature resistant than quartz glass simultaneously, make precision also than quartz glass height, thereby the light efficiency and the color rendering index of Metal halogen lamp have been improved, also improved the consistency of useful life and lamp, these all are that quartz glass is incomparable.
