Abstract
The utility model discloses an electrode of a ceramic metal halide lamp, which comprises a niobium conducting wire, a molybdenum ring, and an electrode tip core rod, wherein the electrode tip core rod is sleeved in the molybdenum ring, one end of the molybdenum ring and one end of the electrode tip core rod are both fixedly connected with the niobium conducting wire, the other end of the electrode tip core rod is wound with a tungsten filament, the diameter of the electrode tip core rod is increased by about 8% to 15mm compared with the diameter of a traditional electrode tip core rod, and the diameter of the finally wound tungsten filament is increased by about 15% to 22mm compared with the diameter of a traditional wound tungsten filament. The luminous maintenance rate of 3,000 hours of the electrode provided by the utility model is up to more than 80%, the light failure is very small, the service life of a bulb is up to 24,000 to 30,000 hours, in addition, the light failure of the whole life cycle is very small, and the purposes of high quality and low production cost are fulfilled.
Description
Technical field
The utility model relates to a kind of porcelain metal halid lamp electrode.
Background technology
There is a difficult problem restricting all the time the useful life of ceramic gold-halogen lamp at the ceramic gold-halogen lamp production industry; it is exactly ceramic metal halogen lamp pole; because in the pipe of ceramic gold-halogen lamp, working temperature is very high; tube wall load is at 1150-1350 °; halide during work in lamp and electrode material produce chemical reaction; cause bulb life can't reach requirement designed life; and existing electrode structure has the patent of some major companies of American-European countries to protect layer by layer; domestic enterprise wants to break through and has run into very large difficulty, only has 9000-12000 hour the useful life of ceramic gold-halogen lamp at present and does not wait.If the use ceramet, the finished product production cost is high, product sexual valence ratio.
The utility model content
The purpose of this utility model is to provide a kind of porcelain metal halid lamp electrode.3000 hours lumen depreciations of electrode of the present utility model can reach more than 80%, and light decay is very little, and bulb life can be worked 24000-30000 hour, and whole life cycle light decay is very little, has realized high-quality low-cost production.
In order to achieve the above object, the technical solution of the utility model is:
A kind of porcelain metal halid lamp electrode comprises the niobium seal wire, molybdenum circle, electrode tip plug; Be set with the electrode tip plug in wherein said molybdenum circle, and an end of described molybdenum circle and electrode tip plug is connected with the welding of niobium seal wire all; Be wound with tungsten filament on the other end of described electrode tip plug; The diameter of described electrode tip plug increases by 8 percent to 15 millimeters with respect to the diameter of traditional electrode tip plug; Diameter after diameter after described tungsten filament is wound around is wound around with respect to traditional tungsten filament increases by five to 22 millimeters of ten Percents.
The beneficial effects of the utility model are: a kind of porcelain metal halid lamp electrode of the present utility model, on traditional basis, the electrode plug is improved, simultaneously the cooling ring of electrode improved, make whole electrode performance that the variation of matter occur, through the bulb test, lumen depreciation can reach more than 80% in 3000 hours, and light decay is very little, bulb life can be worked 24000-30000 hour, had broken through the life-span bottleneck problem of traditional handicraft.And whole life cycle light decay is very little, is applicable to from the porcelain metal halid lamp electrode between power 35W-70W; Realized high-quality low-cost production.
