Abstract
A double-head halogen tungsten lamp bulb comprises a filament (1), a glass tube (2), a exhaust pipe (3), a molybdenum sheet (4), a molybdenum rod, etc. The exhaust pipe is connected at one end of the glass pipe and not only plays the action of exhausting the gas, but also is connected with the molybdenum sheet with airtightness. The structure can cause the pressure of the mixed gas which is filled in the bulb to be higher, thus enhancing the luminous efficiency of the bulb and extending the service life of the bulb.
Description
The utility model belongs to lighting technology, is used for all kinds of light fixtures in line voltage work.
Be widely used in the double end tungsten halogen lamp pipe of line voltage now, its structure mainly is made up of filament, bracket loop, glass-tube, blast pipe, molybdenum sheet, molybdenum rod etc.The filament two ends are welded on the molybdenum sheet, the welding of the molybdenum sheet other end and molybdenum rod.When filament is longer, need around last several bracket loops with filament supports.Flatten at the glass-tube two ends, makes itself and molybdenum sheet form hermetic seal.Blast pipe is connected on glass-tube middle part, when exhaust finishes at the blast pipe root with the sealed-off of halogen tungsten fluorescent tube.This type of double end tungsten halogen lamp pipe charges into that mixture pressure is not high, and the fluorescent tube light efficiency is lower, and the life-span owes long, and the fluorescent tube middle part is residual blast pipe, has influence on outward appearance.
The purpose of this utility model provides and a kind ofly can improve light efficiency, life-saving and outward appearance double end tungsten halogen lamp bubble preferably.
The method that achieves the above object is to make a kind of double end tungsten halogen lamp bubble, and it is made up of filament [1], glass-tube [2], blast pipe [3], molybdenum sheet [4] and molybdenum rod [5] etc.Be characterized in blast pipe [3] is connected on glass-tube [2] one ends, it had both played scavenging action, again with the molybdenum sheet hermetic seal of an end.
Fig. 1 is a double end tungsten halogen lamp bubble structure schematic diagram.
Fig. 2 is that bulb is played recessed double end tungsten halogen lamp bubble structure schematic diagram.
Fig. 3 is the structural representation that the double end tungsten halogen lamp bubble of bracket loop is arranged.
As shown in Figure 1, the double end tungsten halogen lamp bubble is made up of filament [1], glass-tube [2], blast pipe [3], molybdenum sheet [4] and molybdenum rod [5] etc.The filament two ends are welded on the molybdenum sheet, the molybdenum sheet other end and molybdenum rod welding.Blast pipe is connected on an end of glass-tube.It had both played scavenging action, and the molybdenum sheet with an end forms hermetic seal again.The molybdenum sheet press seal of the glass-tube openend and the other end forms hermetic seal.When filament is longer, can on glass-tube, beat the recessed filament supports of coming, as shown in Figure 2.Also can add bracket loop [6] and come filament supports, as shown in Figure 3.
Compare with existing halide-tungsten fluorescent lamp, the blast pipe of Double-head halogen tungstem lamp bulb is connected on glass-tube one end, works as envelope During from bulb, most cell-shells can be immersed in the liquid nitrogen and cool off the enrichment mist. Thereby can Filling mixture pressure in the bulb highlyer, thereby bulb life is prolonged, light efficiency can design Higher. The cell-shell middle part does not have residual blast pipe, and outward appearance is better.
Claims (1)
