Background technology
High voltage mercury lamp is to be filled with hydrargyrum and halogens, in cell-shell in the quartz glass ball electric discharge cell-shell sealed
Two electrodes that the pole tip of electrode is relative are set simultaneously, two electrodes by cell-shell two ends lamp base draw,
One end passes Lamp cup, and the other end passes ceramic head.When two electrodes connect startup high voltage, two electrodes
Between because of produce high potential difference cause generation high heat, liquid mercury now in the case of this high heat turn
Becoming high-pressure mercury vapor, high-pressure mercury vapor is stimulated and the generation light source that discharges in the case of potential difference, has started
Cheng Hou, two the most interelectrode voltages slowly change into normal voltage after reducing rapidly.Owing to mercury vapour is stimulated
Electric discharge, forms electrical discharge arc center between two electrodes, sends the astigmatism line of high brightness, by reflector profit
By optical principle, astigmatism source is changed into source of parallel light refocusing and penetrate, the brightness of a monolithic devices can be formed
Light source, this light source is used for stage performance, gymnasium match, the exhibition of clothing catwalk, car exhibition, etc. a series of
Application.Existing high voltage mercury lamp is low due to power, and light utilization efficiency is low, it is impossible to meets large-scale performance and brings
On-the-spot rendered atmosphere, and limited, also by electric arc tube and the manufacturing process of electrode, pressure, temperature capability
It is difficult to improve further total luminous intensity of ultrahigh pressure mercury lamp, thus limits thus hinder light of stage
Process.
Publication No. is that the Chinese invention patent of CN 1466169A discloses a kind of ultrahigh pressure mercury lamp, is provided with ball sealer
Shape or elliposoidal discharge tube, be provided with sparking electrode in discharge tube, electrode is by sealing-in molybdenum sheet and discharge tube lead-out wire
Electrical connection, is filled with hydrargyrum and the bromide of hydrargyrum, argon or xenon in discharge tube, it is characterised in that: also it is filled with in discharge tube
The halogenide of gallium and the halogenide of indium.This mode improves the brightness of mercury lamp to a certain extent, but light intensity
Still having deficiency, and implant is complex, technological requirement is high.Based on this, how to provide the one can be big
Width improves the high voltage mercury lamp of brightness, becomes the problem needing in the industry solution badly.
Utility model content
In order to solve the problems referred to above, the utility model proposes a kind of high voltage mercury lamp.
The technical solution of the utility model is achieved in that
A kind of high voltage mercury lamp, including being filled with the electric discharge cell-shell of hydrargyrum and halogens, being located at described electric discharge cell-shell

With the second electrode, described first electrode connects described first lamp base, and described second electrode connects described second lamp
Foot, is provided with confined space, is filled with noble gas in described sealing space in described first electrode.
Further, described second electrode connects electric connection part, and described electric connection part is along described discharging bulb
Shell arranges and is connected with described first lamp base.
Further, described electric connection part is tungsten filament.
Further, described first electrode and described second electrode all include molybdenum ribbon, and are separated into by described molybdenum ribbon
Two parts.
Further, described electric discharge cell-shell is that quartz glass is made.
Further, described first lamp base and described second lamp base are guided into outer end by molybdenum ribbon.
Further, described noble gas is xenon.
The beneficial effects of the utility model:
This utility model high voltage mercury lamp on startup, can execute simultaneously by the startup voltage of the first lamp base and the second lamp base
Being added in the first electrode, the two ends of the second electrode, the xenon in cell-shell receives the high-voltage starting voltage simultaneously
The effect of difference, can hit at the voltage of 3.1 3.3KV owing to the discharge breakdown voltage of the noble gases such as xenon is lower
Wearing electric discharge, leap due to the idea of atomic layer and release energy, this energy discharges unexpectedly in the way of light energy
And produce stronger light, on the in-plant hydrargyrum being radiated in electric discharge cell-shell of this light, so that liquid
Hydrargyrum excites rapidly and discharges, and the cell-shell hydrargyrum that so discharges produces electron number and is greatly increased because of ionization, causes and puts bubble
In shell, hydrargyrum breakdown voltage is substantially reduced.
