Description

Ceramic metal halide lamp arc tube
Technical field
The present invention relates to the electric light source technology field, is a kind of ceramic metal halide lamp arc tube.
Background technology
For overcoming the existing shortcoming of quartz metal halide lamp, a kind of metal halide lamp adopts polycrystalline translucent aluminum oxide ceramic to substitute quartz ampoule.As the Granted publication CN1316552C of Chinese patent literature publication, May 16 2007 Granted publication day, patent No. ZL03131897.5, denomination of invention: metal halide lamp electric arc tube; The Granted publication CN100423173C of Chinese patent literature publication, October 1 2008 Granted publication day, patent No. ZL200510110257.3, denomination of invention: ceramic metal halide lamp arc tube.These metal halide lamps have been realized heavy-duty service, color rendering index rises to more than 90, luminous efficiency is compared with quartz metal halide lamp and is improved 20%, life-span is enhanced about more than once, be described as the title of " simulated sunlight ", be that illuminating effect is better in the lighting source, the preferable and application prospect of energy-saving efficiency is the high intensity discharge light source preferably.To the research and development and the industrialization of ceramic metal helide lamp, be of great significance to setting up conservation-minded society.But above-mentioned structural design also exists unsatisfactory part.
Summary of the invention
For overcoming above-mentioned deficiency, a kind of ceramic metal halide lamp arc tube of providing to this area is provided, make it can solve existing like product structural design and wait improved technical problem, the present invention realizes by the following technical solutions.
A kind of ceramic metal halide lamp arc tube, this electric arc tube comprises the person in charge, tail pipe, electrode assemblie, glass solder, ceramic discharge chamber, filler, be responsible for the tail pipe that two ends are respectively equipped with symmetry, be provided with transition region between the tail pipe and the person in charge, the person in charge, tail pipe and transition region arcing pipe, in the electric arc tube is the cavity in ceramic discharge chamber, and its electric arc tube is with high-purity a-Al 2O 3Polycrystalline translucent aluminum oxide ceramic is that material calcination is made type, and electrode assemblie inserts in the ceramic discharge chamber by tail pipe, by glass solder with electrode assemblie and tail pipe clearance seal.Its key points in design is that outer diametric plane and the person in charge, the tail pipe of described transition region is vertical, is
Figure C20081016250200031
It is conical that type, the ceramic discharge chamber of transition region aperture surface are, and fills metal halide, mercury, buffer gas in the ceramic discharge chamber, and the junction of aperture surface and tail pipe is provided with embossed area.A-Al 2O 3The polycrystalline translucent aluminum oxide ceramic discharge cavity is the structure of pyramid type band embossed area, plays the effect that improves cold junction temperature, thereby improves light efficiency and color rendering index, prevents from that halide from flowing into to produce in the tail pipe that dodging boils influences the operate as normal of lamp.Conical embossed area structure guarantees sealing-in district uniform distribution of temperature, guarantees hermetic seal and reduces the thermal radiation energy loss as far as possible; Simultaneously, make the temperature gradient of whole electric arc tube reasonable, the stable working state of lamp.Enclose pair of electrodes at discharge cavity tail pipe two ends, be filled with metal halides such as buffer gas, mercury and luminescent substance, metal lead wire adopts the special glass scolder to realize hermetic seal with pottery, and sealing temperature is at 1400~1600 ℃.
The described person in charge, tail pipe and transition region form an integral body behind sintering, static pressure and dry bag die cast such as be responsible for, tail pipe all adopts.Both will be responsible for after roasting and symmetrical expression tail pipe assembling in different biscuiting temperature, and to adopt interference fit at high temperature to carry out sinter molding be holistic earthenware discharge cavity.The ceramic discharge chamber is to carry out the transition to straight pipe type by pyramid type band embossed area to be responsible for such structure, and there is a straight-through aperture at symmetrical expression tail pipe center, is 0.02mm through the 0.8mm tolerance is arranged directly, is used for the installing electrodes assembly.
The external diameter shape that the outer diametric plane of described transition region and the person in charge, tail pipe three constitute or tapered.The junction that aperture surface is provided with tail pipe is provided with embossed area, and its operation principle is identical with the body that is "-" type.
Above-mentioned ceramic metal helide lamp power is 20W~1500W.After the electrode assemblie conduction, the metal halide in the ceramic discharge chamber, mercury, buffer gas and electric current generation exoelectrical reaction, the thermal radiation Conversion of energy is a luminous energy, and illumination is provided.
The present invention design is comparatively reasonable, simple in structure, has advantages of higher stability, color rendering, light efficiency, and the characteristics of long, miniaturization in useful life are applicable in the assembling illumination lamp body, and the illumination in places such as show window, market, the car show Room, shopping street.
