Abstract
The invention discloses a cold cathode dimming non-filament light source. The cold cathode dimming non-filament light source comprises a tube in which hydrargyrum and inert gas fill; fluorescent powder is coated on the inner wall of the tube; suspended electrode structures are respectively arranged in two ends of the tube. According to the cold cathode dimming non-filament light source, the lightning protection rod type electrode is utilized for resisting the arc attack of a light; harmful arc root heat point is converted into the energy beneficial for electronic emission, and therefore, the service life of the electrode of a fluorescent lamp can be greatly prolonged.
Description
Technical field
The present invention relates to without filament light sources field, specifically a kind of cold cathode light modulation is without filament light sources.
Background technology
In the lighting of prior art, tradition has that the light source existence and stability of filament is poor, the life-span is long, loss is large, caloric value temperature is high, the problem of volume greatly, not with light modulation, and therefore the demand of cold cathode lamp is increasing.Current cold cathode light modulation is without the bottleneck also difficult breakthrough at home of filament lamp light source technology, and cold cathode luminous source is difficult to reach high power device wide-range voltage at present and uses, and the integrated heat dissipation problem that makes of power density type is difficult to resolve certainly, and cause light decay large, useful life is short.Cost performance is too low, and therefore common cold cloudy lamp illumination has price but no buyers for many years, is difficult to open up markets.
summary of the inventionthe object of this invention is to provide a kind of cold cathode light modulation without filament light sources, to solve the light modulation of prior art cold cathode without filament light sources Problems existing.
In order to achieve the above object, the technical solution adopted in the present invention is:
Cold cathode light modulation is without filament light sources, it is characterized in that: include fluorescent tube, mercury and inert gas is filled with in fluorescent tube, tube inner wall scribbles fluorescent material, be respectively arranged with electrode in lamp tube ends, each electrode is connected to the conductive filament passed from fluorescent tube corresponding end, forms hovering and put electrode structure in lamp tube ends, and hovering puts the two electrodes electronic powder identical with starter or cold cathode electron powder in electrode structure, namely electrode is made up of electronic powder or cold cathode electron powder.
Described cold cathode light modulation, without filament light sources, is characterized in that: the fluorescent material of described tube inner wall coating is High-strength pure tricolor powder.
Described cold cathode light modulation, without filament light sources, is characterized in that: be respectively arranged with multiple electrode in lamp tube ends, and the multiple electrodes often held pass the conductive filament external power supply of fluorescent tube corresponding end jointly by one.
Operation principle of the present invention is: after high pressure is added in lamp tube ends, secondary is produced after minority electrons high-speed impact electrode in fluorescent tube, start electric discharge, mercury in pipe is by after electronic impact, exciting radiation goes out the ultraviolet light of 253.7nm, the ultraviolet excitation produced is coated in the fluorescent material on inside pipe wall and produces visible ray (color of visible ray is different by the difference according to selected fluorescent material), fluorescent tube under electric field action, there is gas discharge, release of radiation energy, excitated fluorescent powder produces luminescent effect.
The present invention utilizes the termination of two conductive filaments in the fluorescent tube a branch of suspended electrode of each access respectively; Outstanding the electrode processed electronic powder identical with starter or cold cathode electron powder, need not metallic plate or metal mesh shield, do not need to increase contact conductor in addition yet, lamp electric arc is met to bombard with the electrode of " lightning rod " formula, and harmful electric arc root focus is converted into the energy being conducive to electron emission, greatly extend the life-span of fluorescent lamp electrode." lightning rod is theoretical ", " electric arc root hot spot theory " " point discharge is theoretical " " electron cloud model " etc. are mixed together by the present invention, realize cold cathode light modulation that cold cathode and hot cathode exist jointly and filament-free fluorescent lamp tube long-life novel electrode, effectively can stop the anticathode impact of mercury ion in fluorescent tube, and effectively reduce the temperature of focus, thus realize the significantly lifting of cathode life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Shown in Figure 1, cold cathode light modulation is without filament light sources, include fluorescent tube 1, be filled with mercury and inert gas 2 in fluorescent tube 1, fluorescent tube 1 inwall scribbles fluorescent material 3, and fluorescent tube 1 is respectively arranged with electrode 4 in two ends, each electrode 4 is connected to the conductive filament 5 passed from fluorescent tube 1 corresponding end, in fluorescent tube 1 two ends, form hovering put electrode structure, and hovering puts two electrodes 4 electronic powder identical with starter or cold cathode electron powder in electrode structure, namely electrode is made up of electronic powder or cold cathode electron powder.
The fluorescent material 3 of fluorescent tube 1 inwall coating is High-strength pure tricolor powder.
Fluorescent tube 1 is respectively arranged with multiple electrode in two ends, and the multiple electrodes often held pass conductive filament 5 external power supply of fluorescent tube 1 corresponding end jointly by one.
The present invention has energy-conservation, life-span is long, resistance to switching surge, life-span can reach more than 50000 hours, the advantage that switch is more than 10000000 times, because cold cathode luminous source negative electrode does not need heating, tube current is about the 1/5-1/10 of fluorescent lamp, and the surface area of negative electrode is large, and lighting tube brightness is not easily decayed, and cathode life increases greatly.Low current is powered and is made that the heating of light source is less, temperature is lower, when being conducive to light fixtureization production, the further flexibility of lamp outer casing Material selec-tion, is not only confined to metal, glass material, number of polymers material can be used for the lamp outer casing of cold cathode luminous source, makes cold cathode lamp more rich and varied.Metal, glass material, number of polymers material can be used for the lamp outer casing of cold cathode luminous source, makes cold cathode lamp more rich and varied.
