Description
Technical field
The present invention relates to a kind of point of discharge light source, especially a kind of hyperbar xenon metal halide point of discharge light source.
Technical background
Point-source of light is the essential condition that produces the long-range light beam.Past is all adopted the compact incandescent lamp of structure, and this light is imitated low, and light is logical little, and the photocentre size is big, can not obtain ideal beam, and short energy consumption height of life-span, can only make the portable type ordinary light source usually.After changing tungsten halogen lamp, situation makes moderate progress, but above-mentioned shortcoming still exists.Closely over several years, situation improves after using small-power (35--50) W Metal halogen lamp instead, but because what wherein charge into is low-pressure argon, therefore, start the logical rising of back light slowly, at least can not start immediately again after lamp extinguishes near stable after needing to wait for 5 minutes, need cooling can light once more after 5 minutes, interelectrode distance is bigger simultaneously, cause focusing effect poor, as shorten interelectrode distance and will cause the life-span seriously to shorten, operating position is difficult to satisfactory.
At present, military affairs, frontier defense, public security, diving or many places such as field work in night, mine press for a kind of generating means of portable high-strength beam of energy-efficient, far firing range, and point source of light is the heart component of this device.
Summary of the invention
The purpose of this invention is to provide a kind of start fast, the life-span is long, energy-efficient, the point-source of light of the portable high-strength beam of far firing range.
For reaching above purpose, technical scheme provided by the invention is: point of discharge light source provided by the present invention is provided with spheroidal or axiolitic electric arc tube 1, electric arc tube two ends are respectively equipped with diameter contraction that is mutually 180 degree angles and first neck body, second neck body that seals, be provided with electrode of first end and electrode of second end in the electric arc tube, electrode of first end and electrode of second end are electrically connected with corresponding outer lead by the electric conductor in the corresponding end neck body respectively.Interelectrode distance is arranged between the 0.5-5mm to form point-source of light, specifically apart from deciding on requirement and power.Electric arc tube still has the sufficiently long life-span when guaranteeing that electrode distance is so near, has taked following technological means: 1, be filled with high-pressure inert gas and an amount of mercury in the electric arc tube, make lamp can start and form high-voltage arc fast and have high light efficiency.Described inert gas comprises xenon, and operating state pressure is 2-8 atmospheric pressure.The consumption of described mercury determines that according to long-pending size of ball foam and power should keep the interior operating state mercury vapour pressure of ball bubble is the 80-100 atmospheric pressure.2, charge into the mixing halogen cycle agent of appropriate amount in the electric arc tube, described halogen cycle agent comprises I, Br, and its consumption guarantees that according to ball bubble size concentration is 1-10ppm (mg/litre) in the ball bubble.In addition, charge into an amount of metal halide in the electric arc tube, as NaI, ScI
3, DyI
3, multiple metal halide admixture such as TlI, its composition depends on the colour temperature requirement, consumption is for guaranteeing that every cubic centimetre reaches 0.2-2mg in the ball bubble, to improve light efficiency and color rendering.The electrode that uses in the lamp adopts the W-Th-Dy-Zr material, and this material comprises the W that 98% content is above, all the other compositions＜2%.Point of discharge light source of the present invention has two kinds of DC operation and alternate current operations, and the former material structure of two electrodes is identical, alternately does the positive and negative electrode running; The latter then has the branch of negative electrode, anode, and different electrode structure is seen accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4, accompanying drawing 5.Point-source of light power provided by the present invention between 5W---150W, can be enlarged to more than the 1000W when needing usually.
It is a kind of in order to produce the point of discharge light source of high strength small divergence angle light beam that the present invention can provide, have and start fast, life-span length, light beam far firing range, portable band, advantage such as energy-efficient, throw light on so can be used for places such as military affairs, frontier defense, public security, coast defence, seafari, field work in night, mine.
