Embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
As depicted in figs. 1 and 2 with the explosion-proof single-ended tungsten halogen lamp of linking up with anchored filament, comprise hook 10, filament 20, silk tail 30, molybdenum foil 40, power supply lead body 50, cell-shell 70 and press from both sides flat 80, described hook 10 is fixed on the exhaust point 60, and an end of described filament 20 is supported by described hook 10; Described silk tail 30 directly sandwiches in flat 80 and is connected with molybdenum foil 40, has at least one to be the seal wire of coiling not in two silk tails 30, and the diameter of this seal wire is not less than the diameter of filament 20 tungsten filaments.
Curved " n " shape curved 13 in described hook 10 upper ends, hook 13 width are slightly larger than exhaust point 60 internal diameters, hook 13 is pressed in the exhaust point 60, hook 10 relies on intrinsic being fixed in the exhaust point 60 from elastic force, and the seam that is slightly less than exhaust point 60 internal diameters by exhaust point 60 and cell-shell 70 joints blocks, in exhaust point 60 top sealed-off processes, flame heat exhaust point 60 makes glass melting and wraps part hook 10, and can adopt press-sealing process, part is linked up with 10 sandwich in the exhaust point 60, form connection forever.
Described hook 10 belows are bent to a hook at least or enclose 12, preferentially adopt two hooks or enclose 12, are used for filament supports 20, filament 20 are supported to types such as " n ", " ^ ".
Article two, at least one be to be 100 μ m to the maximum in the silk tail 30 with diameter, the wire producing that preferentially is 80 μ m to the maximum, it presss from both sides among flat 80 by having at least 2mm to sandwich cell-shell, when in the middle of two silk tails 30, producing electric arc, silk tail 30 sandwiches that lead can blow rapidly in flat 80, electric arc extinguishes earlier, thereby prevents the blast of tungsten halogen lamp.
Because silk tail 30 diameters of wire require less than 100 μ m, thereby can directly fire by filament 20 same materials and form, thus applicable greater than 80V, and power is the 20-200W halogen tungsten bulb, but is not precluded within other discharge lamp, the use of incandescent lamp.
As shown in Figure 3 and Figure 4 with the explosion-proof single-ended tungsten halogen lamp of linking up with anchored filament, comprise hook 10, filament 20, silk tail 30, molybdenum foil 40, power supply lead body 50, cell-shell 70 and press from both sides flat 80, described hook 10 is fixed on the cell-shell 70, and an end of described filament 20 is supported by described hook 10; Described silk tail 30 directly sandwiches in flat 80 and is connected with molybdenum foil 40, has at least one to be the seal wire of coiling not in two silk tails 30, and the diameter of this seal wire is not less than the diameter of filament 20 tungsten filaments.
Hook 10 coiled annulars 11 on the inwall of described cell-shell 70 contact fixing with cell-shell 70, stretch out link 12 in the middle of the annular 11 and be used for filament supports 20.
Described hook 10 belows are bent to a hook at least or enclose 12, preferentially adopt two hooks or enclose 12, are used for filament supports 20, filament 20 are supported to types such as " n ", " ^ ".
Article two, at least one be to be 100 μ m to the maximum in the silk tail 30 with diameter, the wire producing that preferentially is 80 μ m to the maximum, it presss from both sides among flat 80 by having at least 2mm to sandwich cell-shell, when in the middle of two silk tails 30, producing electric arc, silk tail 30 sandwiches that lead can blow rapidly in flat 80, electric arc extinguishes earlier, thereby prevents the blast of tungsten halogen lamp.
Because silk tail 30 diameters of wire require less than 100 μ m, thereby can directly fire by filament 20 same materials and form, thus applicable greater than 80V, and power is the 20-200W halogen tungsten bulb, but is not precluded within other discharge lamp, the use of incandescent lamp.
In above-mentioned two embodiment, exhaust point 60, cell-shell 70 and folder flat 80 are with a kind of glass material; Hook 10, molybdenum foil 40 and power supply lead body 50 are molybdenum or refractory metal; Filament 20, silk tail 30 are tungsten, but exclusive segment does not adopt other refractory metal material.
The utility model has adopted from the scheme of exhaust point internal fixation hook, or by the scheme of hook fixing on the cell-shell wall, filament is supported for " n ", " ^ " type.Broken away from and used the bead supporting way in the past, make in the bulb that solid material reduces to minimum except that the luminous element filament, be easy to the degasification of tungsten halogen lamp and the venting of minimizing later stage in life-span material inside bulb more, it is cylindrical that cell-shell keeps, and the halogen tungsten circulation reaches perfect condition in the bulb.
What is more important, filament are broken away from after the bead constraint, a silk tail just can directly sandwich the cell-shell folder flat among, connect 80V voltage at least at this Halogen lamp LED, a silk tail has intrinsic safety effect.At this intrinsic safety effect is to realize like this, article two, at least one be to be 100 μ m to the maximum in the silk tail with diameter, the wire producing that preferentially is 80 μ m to the maximum, it by have at least 2mm sandwich cell-shell folder flat among, when in the middle of two silk tails, producing electric arc, the silk tail sandwiches flat middle lead and can blow rapidly, and electric arc extinguishes earlier, thereby prevents the Halogen lamp LED blast.
Owing to abandoned bead, light is not owing to have bead to block and absorb, and light efficiency has improved about 1-2Lm/W, the effect of play energy savings, saving cost.And, saved cost because there is not bead to simplify the production process flow process.
Enforcement of the present utility model is not limited to the disclosed mode of above each embodiment, based on mentality of designing of the present utility model, simply deduces and replaces, and also all belongs to enforcement of the present utility model.
