Abstract
The utility model is a compound electrode fluorescent lamp, consisting of a lamp tube and a lighting circuit, wherein the lamp tube is provided with two compound electrodes; and each the electrode consists of an indium net, a hot cathode, an amalgam and a wire, wherein the hot cathode is a spiral tungsten filament of which the surface is coated with oxide electronic powder; and the amalgam is manufactured into a closed round ring which is used as a cold electrode. After the lamp is powered on, a resonance network generates resonances under the action of high frequency voltage output by the lighting circuit, thereby generating high impulses; when the generated high impulses are applied to the lamp tube, the lamp tube is lightened. Simultaneously, the voltage of the lighting circuit is applied to the amalgam, so that an alternating electric field is generated, and bombardment of positive ions is attracted, thereby greatly reducing sputtering of the hot cathode and prolonging the service life of the lamp. The lighting effect of the lamp reaches the national first level, the service life of the lamp is 2000 hours on average, and the residual mercury is within a standard range which is allowable in America and European Union.
Description
One, technical field
The utility model is the novel long-life fluorescent lamp, belongs to daily lighting electric light source.Current country promotes and the electricity-saving lamp of market sale, mainly has outstanding problems such as weak point, liquid mercury pollution environment in useful life.The utility model adopts the combination electrode mode of operation; Use liquid amalgam; Not only making the life-span of lamp exceed several times than common energy-saving lamp, but also effectively overcome above-mentioned electricity-saving lamp many defectives such as " only energy-conservation not environmental protection ", is the new type electro source of a kind of long-life, high light efficiency, true environmental protection.
Two, background technology
As everyone knows, gas discharge can produce electric energy → transform light energy, utilizes gas discharge phenomenon to make existing more than the 100 year history of all kinds of electric light sources.Electricity-saving lamp is the gaseous discharge lamp of using always, employing be hot cathode mode of operation and electronic circuit instantaneous starting method.Lamp is when starting, and hot cathode also is in " cold " state, does not have thermionic emission this moment; In the process gas discharge; Cation after the ionization is forcing the hot cathode emitting electrons of " cold " state with great kinetic energy bombardment hot cathode, causes a large amount of sputters of emitting material on the hot cathode; Thereby hot cathode was lost efficacy very soon, cause fluorescent tube to damage.
Generally charge into liquid mercury in the fluorescent tube of electricity-saving lamp, possibly pollute, do not meet environmental requirement environment.Present American-European developed country has made laws and has forbidden the sale of liquid mercury electricity-saving lamp.
Three, utility model content
What the utility model adopted is a kind of combination electrode (being bipolar electrode) mode of operation, at coated outside one deck cold cathode of hot cathode, when lamp starts; According to the third law of thermodynamics (it is maximum that entropy becomes); What cation at first bombarded is cold cathode, when cation in bombardment during cold cathode, hot cathode has reached normal working temperature through of short duration preheating; The emitting material sputtering phenomenon reduces in a large number on the hot cathode thereby make, thereby has greatly prolonged the useful life of lamp.And cold cathode uses is solid-state amalgam, overcomes and has prevented the severe contamination that uses liquid mercury that environment is brought.
About lamp circuit, what the utility model adopted is the semiconductor integrated technology, has increased kinds of protect measures such as anticathode overheated, the overload of circuit, zero load, the performance of the utility model has been had significantly improve.And price is suitable with market brand electricity-saving lamp, and cost performance of product is compared with other electricity-saving lamp, has very outstanding advantage.
Below in conjunction with accompanying drawing, the utility model is described further.
Four, description of drawings
Fig. 1 is combined electrode structure figure, is made up of indium net (1), hot cathode (2), amalgam (3), lead (4).Indium net (1) is in order to absorbing the mercuryvapour that amalgam (3) discharges after decomposing in the fluorescent tube, and hot cathode is protected, and point is welded on the amalgam (3); Hot cathode (2) is a helical tungsten filamen, surfaces coated oxide electronics powder; Amalgam (3) is the strip metal sheet, one side amalgamate titanium alloy, and another side is coated with the Zr-Al compound getter, can discharge mercuryvapour under certain condition.Amalgam (3) is made into closed circle, and as cold electrode, point is welded in and is connected on the lead (4).
Fig. 2 is the structural representation of whole lamp, and whole lamp is made up of fluorescent tube (5) and lamp circuit (6).Fluorescent tube (5) is the fluorescent tube of surfaces coated fluorescent material, has two above-mentioned combination electrodes.Lamp circuit (6) is formed incorporate whole lamp thus for the electric ballast of output 50-100KHz high frequency voltage.
Five, embodiment
In the embodiment shown in Figure 2, fluorescent tube is the U type, has two combination electrodes.
During lamp work, lamp circuit (6) output 50-100KHz high frequency voltage, promptly the lamp current direction makes the resonant network generation resonance of electric ballast with the frequency change of 50-100KHz, on combination electrode, produces high-voltage pulse, is applied on the fluorescent tube (5), lights fluorescent tube.The voltage of lamp circuit (6) is applied on the amalgam (3) simultaneously, produces alternating electric field, attracts the bombardment of cation, significantly reduces the sputter of hot cathode (2), greatly prolongs the life-span of lamp.
Beneficial effect
The utility model is compared with general electricity-saving lamp, has many outstanding operating characteristic.
1, start moment when lamp, the hot cathode of combination electrode receives the protection of indium net and amalgam, has alleviated the energy of cation to the hot cathode bombardment greatly, and the while has also reduced the sputtering phenomenon of hot cathode when emitting material.
2, lamp circuit is provided with the preheating program to hot cathode, makes hot cathode guarantee all the time under normal condition, to work.
3, two kinds of negative electrodes work simultaneously, the load when having alleviated wherein any negative electrode and working alone.
Experiment through to the utility model finds that the cathodic region did not have obvious sputter when lamp started, and working just had slight sputtering phenomenon after 1500 hours.And common energy-saving lamp is as long as work just had cathodic sputtering layer clearly in tens hours.
The measured result of the utility model product is: light efficiency 70lm/w.Reach country-level efficiency; Life-span average out to 20000 hours is the several times of electricity-saving lamp; Cost and electricity-saving lamp are roughly similar; Mercury remains in the U.S. and European Union allows in the critical field.
