Abstract

The utility model discloses a glow starter, comprising a pair of guide wires which are used as two electrodes of the glow starter; a glass connecting section is arranged at one end of the guide wire, and the guide wires and the glass connecting section form a core column of the glow starter, a layer of glow-starting coating is coated on the upper end surface of the glass connecting section, double metal sheets are welded on the upper end surface of the guide wire of the glass connecting section, and the core column is externally provided with a glass shell. The glow starter discards radioactive isotopes, aluminium powder is used to lead the glow starter to generate weak current when in electric conduction, at the same time, zinc-copper sulfide can give out weal light under the action of the current, by virtue of the double actions of the current and the light, the glow starter generates avalanche which is transited to visible flow discharge. As the radioactive isotopes are not used, the starter is environmental-protection; in addition, the structure is simple and is easy to production.

Description

Glow starter

Technical field

The utility model relates to a kind of fluorescent lamp starting device, and particularly a kind of starter is effective and do not have an alpha-contamination glow starter.

Background technology

Glow starter is airtight, charges into working gas after being evacuated.Generally it is in parallel with fluorescent lamp together with parts such as electric capacity, behind power connection, effect owing to voltage between the interior electrode of glow starter makes gas ionization produce glow discharge, and electric energy has become heat energy, and bimetal leaf produces distortion until contacting with another electrode under the temperature action that raises.At this moment owing to short circuit, glow starter has not had voltage, and glow discharge also disappears thereupon.Meanwhile ballast, filament and glow starter have formed a loop, and filament has obtained effective preheating.Glow starter is because lose glow discharge, and temperature reduces gradually, and bimetallic sector-meeting at a certain temperature returns to the original form and leaves another electrode.Disconnect in a flash because the physical characteristic effect meeting of ballast produces a reverse electromotive force.Under this electromotive force effect, fluorescent lamp might be lighted, and the voltage at glow starter the two poles of the earth has become that pipe is pressed and not in work from supply voltage when the time comes.If being lighted, fluorescent lamp will not repeat said process till being lighted.

As previously mentioned, glow starter begins glow discharge under certain voltage effect, but this process must possess a condition: the initial discharge before visible glow discharge.This discharge normally produces under the effect of photon or radioisotopic free electron, if there is not this initial discharge, " snowslide " just can not take place to visible glow discharge in glow starter, so initial discharge is the precondition of glow starter work, and the operational environment of fluorescent lamp has determined starter generally to work under dark state, so IEC60155 and GB20550 have stipulated starter and must deposit more than 15 hours under the dark state before test, and tested under dark state.At this moment glow starter can't accept the effect of photon fully, and common way is to use radioisotope in order to address this problem at present, utilizes isotopic free electron to help glow starter work, as Kr ⁸⁵, H ³, Pm ¹⁴⁷, Ni ⁶³Deng, but along with the progress of society, the reinforcement of countries in the world environmental consciousness, radioactive use will be subjected to more and more strict restriction.

Summary of the invention

Goal of the invention: technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of life-span long, the swift glow starter of starter.

Technical scheme: the utility model discloses a kind of glow starter, comprising:

A pair of seal wire is as two electrodes of glow starter;

At seal wire one end the glass linkage section is set, described seal wire and the stem stem that connects glass linkage section formation glow starter;

Be coated with one deck starter layer in described glass linkage section upper surface;

Seal wire upper surface at described glass linkage section is welded with bimetal leaf;

Described stem stem is provided with glass shell outward.

In the utility model, preferably, described glass linkage section is tubaeform.

In the utility model, preferably, described starter layer is the starter layer that silver powder and zinc sulphide copper mixture constitute.Described sulfuration zinc-copper is the mixture of zinc sulphide and copper nitrate.

Beneficial effect: glow starter described in the utility model is abandoned radioisotope, utilize silver powder to make glow starter when energising, produce extremely faint electric current, vulcanize zinc-copper simultaneously and under the effect of electric current, can send faint light, under the double action of electric current and light, help glow starter that " snowslide " takes place and carry out the transition to visible glow discharge.Since do not use radioisotope, thus environmental protection more, and structure is also simpler simultaneously, is convenient to produce.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is done further to specify, above-mentioned and/or otherwise advantage of the present utility model will become apparent.

Be illustrated as the utility model structural representation.

Embodiment:

As shown in the figure, the utility model discloses a kind of glow starter, it promptly is a glow switch of often opening, it comprises that lower member forms: a pair of seal wire 1, is coated on mixture 5 that stem stem presss from both sides the silver powder at flat place and sulfuration zinc-copper, is arranged on the outer glass shell 6 of stem stem the bimetal leaf 4 on the seal wire that constitute stem stem 3 that the glass linkage section of glass linkage section 2, seal wire and horn shape of two electrodes, the horn shape of glow starter constitutes, is welded on the glass linkage section.

The utility model provides a kind of thinking and method of glow starter; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
