Description
Technical Field
The utility model belongs to the technical field of the illumination lamps and lanterns technique and specifically relates to a stable form deuterium lamp is related to.
Background
Deuterium lamps are glow discharge lamps that require a dedicated power supply to start and operate. According to the characteristics of stable energy, good continuity and the like of a spectral line of deuterium between 190nm and 400nm, a deuterium lamp is the most ideal ultraviolet light source in the prior ultraviolet spectrophotometer, liquid chromatograph and various ultraviolet detectors. The structure of a conventional deuterium lamp is: the deuterium lamp comprises a bulb shell, wherein a press sealing column is fixedly installed in the bulb shell, a core column is fixedly inserted in the press sealing column, a nickel shell is fixedly installed at the upper end of the core column, the material of the press sealing column in the traditional deuterium lamp is quartz, when the traditional deuterium lamp is installed, the core column needs to be wrapped by the fused quartz, but the quartz is cooled quickly and shaped quickly, the quartz can be shaped after wrapping the core column, the upper surface of the press sealing column cannot be pressed flat, burrs are formed on the upper surface of the press sealing column when the traditional deuterium lamp is discharged, and the quartz press sealing column can be cracked if the burrs are forcibly pressed flat; the core column in the traditional deuterium lamp is made of molybdenum wires, and the molybdenum wires are soft and have poor luminescence, so that the service life of the deuterium lamp is influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the material of sealing the post in order to overcome traditional deuterium lamp middling pressure is quartz, and quartz cooling is fast, and is moulding fast, and quartz wraps up behind the stem just can the shaping, and it is too late to flatten the upper surface of pressing the post, and there is the burr on the upper surface of pressing the post, can hit the burr during discharging, if flatten the burr by force, then can seal the problem of post fracturing with quartzy pressure, provide a stable form deuterium lamp.
The utility model provides a technical scheme that its technical problem adopted is: the stable deuterium lamp comprises a bulb shell, wherein a press sealing column is fixedly arranged in the bulb shell, a core column is fixedly inserted in the press sealing column, a nickel shell is fixedly arranged at the upper end of the core column, and the press sealing column is made of glass.
The utility model discloses a stable form deuterium lamp, including the cell-bulb, the fixed mounting presses the post of sealing in the cell-bulb, presses the post internal fixation to insert and is equipped with the stem, and stem upper end fixed mounting has the nickel shell, and the material of pressing the post is glass, when pressing the post of sealing, needs to heat glass to the molten state, then makes the glass parcel stem after the melting, and glass cooling is slow, and plasticity can not be with pressing the post fracturing during plasticity, the deuterium lamp of the invention is comparatively stable.
Traditional deuterium lamp middling pressure seals post's material is quartz, when the installation, needs to make the quartz parcel stem after the melting, but the quartz cooling is fast, and is moulding fast, just can take the plastic shape behind the quartz parcel stem, comes not too late to flatten the upper surface of pressure sealing post, and the upper surface of pressure sealing post has the burr, can hit the burr during discharge, if flatten the burr by force, then can be with the fracturing of quartz pressure sealing post, in order to solve above-mentioned problem, the upper surface of pressure sealing post is the plane, when pressure sealing the stem, needs to heat glass to the molten state, then makes the glass parcel stem after the melting, and glass cooling is slow, and the upper surface of pressure sealing post can flatten once more, and the upper surface of pressure sealing post is the plane, does not have the burr, can not hit the burr during discharge.
The stem in the traditional deuterium lamp is made of molybdenum wires, the molybdenum wires are soft and do not emit light normally, the service life of the deuterium lamp is affected, in order to prolong the service life of the deuterium lamp, the stem is made of tungsten rods, the tungsten rods are high in hardness and do not shake, the light is emitted normally, and the service life of the deuterium lamp can be prolonged.
The utility model has the advantages that the utility model discloses a stable form deuterium lamp, including the cell-shell, the fixed mounting presses the post in the cell-shell, the fixed insertion is equipped with the stem in pressing the post, the fixed mounting of stem upper end has the nickel shell, press the material of post to be glass, press the upper surface of post to be the plane, when pressing the stem, need heat glass to the molten state, then make the glass after the melting wrap up the stem, the glass cooling is slow, press the upper surface of post to flatten once more, press the upper surface of post to be the plane, no burr, can not hit the burr during discharge; the core column is made of a tungsten rod, the tungsten rod is high in hardness, cannot shake, is correct in light emission, and can prolong the service life of the deuterium lamp.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a two-dimensional schematic diagram of the present invention.
In the figure: 1. bulb shell, 2, press sealing column, 3, core column, 4, nickel shell.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, a stable form deuterium lamp, including cell-shell 1, cell-shell 1 internal fixation installs pressure seal post 2, pressure seal post 2 internal fixation inserts and is equipped with stem 3, 3 upper end fixed mounting of stem have nickel shell 4, the material of pressure seal post 2 is glass, the upper surface of pressure seal post 2 is the plane, when pressure seal stem 3, need heat glass to the molten state, then make glass parcel stem 3 after the melting, the glass cooling is slow, the upper surface of pressure seal post 2 can flatten once more, the upper surface of pressure seal post 2 is the plane, no burr, can not hit the burr during discharging.
The stem 3 in the traditional deuterium lamp is made of molybdenum wires which are soft and have irregular light emission, so that the service life of the deuterium lamp is influenced.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
