Abstract
The utility model relates to a deuterium lamp used for analyzing the optical source used by a test apparatus, in particular to an easily triggered deuterium lamp with a nickel casing connected with power, which comprises an anode, a cathode, a nickel casing, and a nickel casing fixed link for fixing the nickel casing, wherein the anode is connected in series with the nickel casing through a resistor, the nickel casing fixed link connected with the nickel casing is extended out a bubble casing, and then the resistor is connected in series between anode conducting wires outside the bubble casing. A resistor of the utility model is connected in series between the anode and the nickel casing of the deuterium lamp, to make the nickel casing had positive potential, to make the whole nickel casing become a grid, thereby the speed that an electron moves to the anode from the cathode is accelerated, the kinetic energy of the electron is improved, to make deuterium gas excitated ionization, the deuterium lamp is easy to trigger, to further ensure that the qualification rate of the deuterium lamp should be improved above 30 percent.
Description
Technical field
The utility model relates to and is used for the deuterium lamp of analytical test instrument with light source, especially a kind of easy triggering deuterium lamp of nickel shell joint electricity.
Background technology
Deuterium lamp belongs to a kind of light source of arc discharge type in the gaseous discharge lamp, can give off 160nm ~ 400nm continuous distribution ultraviolet spectra from optical window during its work, so it is present ultraviolet specrophotometer with desirable ultraviolet source, be filled with in the lamp deuterium gas (～10mmHg), filament voltage Vf＜2～10V, interchange or direct current.Starting voltage Vs～300V dc current regulator power supply supply, operating voltage Va=70～100V behind the build-up of luminance.Operating current～300mA.The luminescence mechanism of deuterium lamp is: the anode motion under electric field quickens of the hot electron of filament cathode emission realizes inelastic collision with deuterium gas molecule and excites, thereby the continuous spectrum of radiation deuterium molecule, deuterium lamp work is to utilize its anode column, therefore intensity is very big, for avoiding the anode arc hot spot, a barrier sheet that has aperture is installed to exclude veiling glare in the anode vertical direction, light is sent from aperture.In a single day deuterium lamp is lighted, delay circuit will cut off filament supply Vf (general filament heating is the several seconds approximately) automatically.The unsuitable Fraquent start of deuterium lamp will be noted the preheating of deuterium lamp in the work, to obtain stable light output.
Because triggering, deuterium lamp need the current energy between negative electrode and the anode very big, but domestic traditional ultraviolet specrophotometer (instrument of main use deuterium lamp) since consider deuterium lamp the design in useful life be used to that to trigger the power of deuterium lamp always lower, voltage is about about 300V, and general in the world trigger voltage standard is 500V, so it is the current energy of domestic power supply is on the low side, relatively poor to the deuterium lamp stimulation effect of present structure.
Summary of the invention
The technical problems to be solved in the utility model is: the triggering performance that improves deuterium lamp.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of easy triggering deuterium lamp of nickel shell joint electricity, comprise anode, negative electrode, nickel shell, cell-shell and the fixing nickel shell fixed lever of nickel shell, and described anode is connected in series with the nickel shell by a resistance.
Further: described anode is by resistance and the form that the nickel shell is connected in series, and is that the nickel shell fixed lever that will link to each other with the nickel shell prolongs and stretches out cell-shell series resistor again and between the outer positive wire of cell-shell.
Furtherly: the resistance of described resistance is 10-15 kilohm.
Principle of the present utility model is: increase by one 10-15 kilohm striking resistance between the anode of deuterium lamp and nickel shell, make the nickel shell by resistance be connected to anode also become positively charged the position (with respect to a negative electrode), this is equivalent to allow whole nickel shell become a grid, because the nickel shell is very near from cathode distance, under very strong electric field, quicken the electronics emission of negative electrode, around negative electrode, produce one deck electron cloud, but this moment is owing to there is 10-15 kilohm resistance to exist in circuit, the electric current that forms is very little, (this process just increases near the density of the ion cloud negative electrode to be not enough to the build-up of luminance of lamp, the savings energy is prepared to trigger), when the lamp power supply adds the operating voltage of about 150 volts of another groups between anode and negative electrode, negative electrode this moment a large amount of electronics on every side move toward anode direction by the grating hole, excite, the ionization deuterium molecule, make it conduction, lamp is smooth build-up of luminance, cuts off trigger voltage simultaneously.
The beneficial effects of the utility model are, the present invention links to each other by a resistance between the anode of deuterium lamp and nickel shell, make the nickel shell position that also becomes positively charged, this is equivalent to allow whole nickel shell become a grid, quickened the speed of electronics, thereby improved the energy of electronics, made deuterium gas excite ionization from the negative electrode anode, thereby guaranteed the triggering performance of deuterium lamp, guaranteed that further the qualification rate raising of deuterium lamp reaches more than 30%.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, anode, 2, negative electrode, 3, the nickel shell, 4, cell-shell, 5, resistance, 6, nickel shell fixed lever.
Embodiment
Easy triggering deuterium lamp cross-section structure as the nickel shell joint electricity of accompanying drawing 1, having overall is columniform clear glass cell-shell 4, anode 1, negative electrode 2, nickel shell 3 and the nickel shell fixed lever 6 that is used for support fixation nickel shell 3, nickel shell fixed lever 6 prolonged and stretch out cell-shell 4, its external part and wiring place of anode 1 outside cell-shell 4 are connected with resistance 5, and the resistance of resistance 5 can be selected with 10-15 kilohm.
In a word, inventive point of the present utility model only is to be connected in series a resistance between the anode of deuterium lamp and nickel shell, make the nickel shell position that also becomes positively charged, make whole nickel shell become a grid, thereby quickened the speed of electronics from the negative electrode anode, improved the momentum of electronics, made deuterium gas excite ionization, easier triggering deuterium lamp.
