Description
Technical field
The invention belongs to ceramic light source field, relate in particular to a kind of ceramic metal halide lamp shell.
Background technology
The translucent alumina pipe of global range mainly contains integral structure at present, two body structures, three body structures, even five body structures, but have a dot structure be substantially identical be that capillary portion all is that the inner surface of straight barrel structure and discharge cavity is quadratic surface structures such as cylinder, ellipsoid, sphere shape substantially.
At present the sealing-in mode that adopts of ceramic gold-halogen lamp manufacturer is that glass solder and earthenware and electrode are together heated in addition, the fusing point of glass solder is lower than the softening point of pottery, and after fusing, need good flowability, and then be penetrated in the gap of ceramic capillary and electrode assemblie, finish the sealing-in of earthenware after cooling.
As shown in Figure 1, ceramic metal halide lamp shell is made of discharge cavity 1 and the capillary 2 of being located at discharge cavity 1 two ends, capillary 2 is straight barrel structure, the sealing-in of the electrode of this structure is to finish with the slit of electrode stem 4 by glass solder 3 filled capillary pipes 2, so just needing has bigger gap between capillary 2 and the electrode stem 4, and bigger gap can cause the halogen thing to enter the gap and bring loss.And prior art is in the part formation horn mouth structure 5 of capillary 2 with discharge cavity 1 handing-over, this structure forms cold spot easily, and golden halogen thing deposition takes place easily at this place, makes the halogen thing all not participate in circulation, and cause its erosion to ceramic gold-halogen lamp, influence into the operating efficiency and the life-span of lamp.
Summary of the invention
At the shortcoming of prior art, the purpose of this invention is to provide that a kind of encapsulation is more simple, the better ceramic metal halide lamp shell of sealing effectiveness.
For achieving the above object, technical scheme of the present invention is: a kind of ceramic metal halide lamp shell, comprise discharge cavity and be located at the capillary at discharge cavity two ends, this capillary comprises interior pipeline section and the welding groove that is connected, pipeline section is near discharge cavity in being somebody's turn to do, welding groove is positioned at the end, and the interior pipeline section of the internal diameter of welding groove is big, and welding groove is realized the gas-tight seal of discharge cavity by filling scolder.
In this programme, adopt and form a welding groove structure in end capillaceous, the mouth of pipe is transferred to by capillary wall in sealing-in position in the past, the diameter of the mouth of pipe is bigger, greatly facilitates to put scolder and finish sealing-in.And scolder melts and finishes sealing-in at welding groove substantially, and does not need to finish sealing-in by the quite long capillary wall that flow to, and mainly is that caliber capillaceous and electrode diameter are suitable, does not have the gap.
In addition, the position of this programme scolder is compared with the residing position of scolder is further from the high arc temperature district in the prior art welding procedure, and length capillaceous can correspondingly reduce, and helps some to the shorter and smaller application of cell-shell yardstick requirement.
The cold junction position of this scheme can effectively be controlled forward, owing to more near the thermal source part, improved cold junction temperature, guarantees the operating pressure of light source.This programme has been removed the horn mouth structure of the part formation of capillary and discharge cavity handing-over, has avoided the low excessively phenomenon of cold junction temperature.
Capillary is high accuracy, high collimation, high-axiality, therefore can realize closely cooperating most of capillary tube inner wall and electrode stem, gap between them can be controlled at the precision less than 5 microns, can prevent that like this luminescent substance from infiltrating in the capillary, improve the life-span of pipe, and increased the axiality of making electrode in the lamp process.
This welding groove be an outside throat structure or this welding groove side be provided with some recessed/the tongue structure, make firm welding Du Genggao, avoided that existing electrode solder is sagging to be flowed, seal imperfect and make into lamp early failure.
The positive camber of this discharge cavity and junction capillaceous are the smooth transition structure, have at utmost reduced stress.
This discharge cavity is an even isothermal surface cavity nonhomogeneous, and it is:
