Description
Affiliated technical field
The present invention relates to electrical apparatus industry, particularly a kind of metal halide lamp electric arc tube.
Background technology
At present, the whole adopting quartz glass materials of domestic metal halide lamp electric arc tube shell are made, since quartz glass at high temperature can with the seepage of a series of chemical reaction of metal halide deposits yields and metal ion, cause the loss of metallic element and the corrosion of electrode, cause lamp in use firing voltage, arc drop and restart voltage and obviously raise, light decay is bigger, and photochromic drift is serious, influence the life-span, thereby limited the performance of lamp and the further raising in life-span.
Because chemical stability, corrosion resistance and the resistance to elevated temperatures of aluminium oxide ceramics obviously are better than quartz glass, in recent years, famous electric light source company of external a few family tears the special aluminium oxide ceramics of huge fund exploitation open as metal halide lamp electric arc tube sheathing material, and has obtained application.But its shell adopts five covers, three-piece or integral sintered forming mostly, but all has the problem of complex manufacturing technology, at present, and the domestic metal halide lamp production of also not making the electric arc tube shell with translucent alumina ceramics.
Summary of the invention
In order to fill the domestic gaps, overcome the deficiencies in the prior art, the present invention proposes a kind of new type of metal halide lamp arc tube.
The technical solution adopted for the present invention to solve the technical problems is: a kind of metal halide lamp electric arc tube, has shell, be provided with electrode in the shell, the electrode rear end is provided with conductive lead wire, shell (1) is made by translucent alumina ceramics, shell is that two body sintering form, two shape is similar, every by thicker cylinder, elongated tail pipe and conical transition tube three parts are formed, and with a compression moulding of mould, the external diameter of one thicker cylinder is slightly larger than the internal diameter of the thicker cylinder of another part, electrode is arranged on conical transition tube position, conductive lead wire is arranged in the elongated tail pipe, and extends to the outside, seals with glass solder with elongated tail pipe.
Further: described two body case are in thicker cylinder position interference fit, under the different temperature respectively after the biscuiting, the cylinder of a shell are inserted the thicker cylinder of another part shell, the high again translucent alumina ceramics shell that burns till an integral body.
Again further: a described shell is made up of elongated tail pipe and conical transition tube two parts, another part shell is made up of thicker cylinder, elongated tail pipe and conical transition tube three parts, the outer end diameter of one conical transition tube is slightly larger than the internal diameter of the thicker cylinder of another part shell, after the biscuiting of two shell difference, the end of the conical transition tube of a shell is inserted in the thicker cylinder of another part shell, and high temperature burns till holistic translucent alumina ceramics shell again.
Again further: the described elongated tail pipe and the joining place R arc transition of conical transition tube.
Also further: be filled with metal halides such as a certain amount of inert gas, mercury and at least a Sc, Na, Tl, In, Dy, Ho, Tm in the middle chamber of described shell.
The invention has the beneficial effects as follows: overcome quartz glass as the intrinsic defective of metal halide lamp electric arc tube shell, it is simple in structure simultaneously, be convenient to make, dimensional uniformity is guaranteed easily, light, electricity, look performance and consistency thereof, the stability of metal halide lamp have been improved greatly, prolong the useful life of lamp, filled up a domestic blank.
