Abstract
The utility model relates to an inorganic nonmetal material and lamp house illumination ceramic pipe, in particular to a ceramic pipe used for a metal halide lamp. The ceramic pipe consists of a first external shell and a second external shell; the first external shell is a structure which integrates a first tail pipe, a first transition part and a cylinder into a whole; the external surface of the first transition part is an arc transition surface; the internal surface of the first transition part is a taper transition surface; the second external shell is an integrated structure connected by a second tail pipe, and a second transition part; the external surface of the second transition part is an arc transition surface; the internal surface of the second transition part is a taper transition surface; the second external shell is inserted in the cylinder of the first external shell by the second transition part, both of which are sealed into an integration by agglutination in order to make the ceramic pipe used by the metal halide lamp. The utility model has reasonable, simple and practical structure design. The half-transparent alumina ceramic pipe made according to the utility model is suitable for making the metal halide lamps ranging from 35W through 400W.
Description
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:
This earthenware is that first shell and second shell two parts constitute, first shell is the integrative-structure that first tail pipe, first transition portion, cylinder are formed by connecting, the outer surface of first transition portion is an arc transiting surface, and the inner surface of first transition portion is the conical transition face; Second shell is the integrative-structure that second tail pipe, second transition portion are formed by connecting, and the outer surface of second transition portion is an arc transiting surface, and the inner surface of second transition portion is the conical transition face; Second shell is plugged in the cylinder of first shell by second transition portion.
Be the sintering sealing structure between described second transition portion and the cylinder.
The beneficial effects of the utility model are:
1, the utility model metal halide lamp earthenware is the plug-in mounting structure of two shells, and its inner space is used for installing electrodes, and the two ends of earthenware are the tail pipes that is used for the extraction electrode lead, and two shells are by the sintering sealing-in, and it is simple in structure, practical; Simultaneously, the outer surface of shell transition portion is an arc transiting surface, and inner surface is the conical transition face, makes its structural design more reasonable, is beneficial 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.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1 first shell; 11 first tail pipes; 12 first transition portions; 13 cylinders; 2 second shells; 21 second tail pipes; 22 second transition portions.
Embodiment
Below by drawings and Examples the utility model is elaborated.
As shown in Figure 1, the utility model metal halide lamp earthenware is made up of first shell 1 and second shell, 2 two parts, and second shell 2 is plugged in first shell 1.Wherein, the integrative-structure that first shell 1 is formed by connecting for thinner first tail pipe 11, first transition portion 12, thicker cylinder 13, the outer surface of first transition portion 12 are arc transiting surface, and the inner surface of first transition portion 12 is the conical transition face; Second shell 2 is the second thinner tail pipe 21, the integrative-structure that second transition portion 22 is formed by connecting, and the outer surface of second transition portion 22 is an arc transiting surface, and the inner surface of second transition portion 22 is the conical transition face.Second shell 2 is plugged in the cylinder 13 of first shell 1 by second transition portion 22, by the sintering sealing-in, makes the metal halide lamp earthenware.
According to the translucent alumina ceramics pipe that the utility model is made, be applicable to the metal halide lamp of making 35W-400W.
