Abstract

A starter belongs to an automatic time delay switch for preheat starting of fluorescent lamp. One polar plan of the pressure sensitive film is welded with a non-distortion electrode. The other polar plane thereof is welded with a heat distortion electrode. The non-distortion electrode is connected and fixed on a guiding wire of a core column. The contact of the heat distortion electrode contacts with the other guiding wire of the core column. The glass envelope is directly connected with the core column. The closed type device is composed through filling with inert gas after vacuum pumping. The heater is started after preheating and can be totally closed in using. The starter does not consume power after the lamp works normally. The starter does not produce heat and totally accord with the characteristic requirement for preheating the fluorescent lamp.

Description

A kind of starter

Technical field

The present invention relates to the starter that a kind of fluorescent lamp pipeline start up by preheating is used.

Background technology

At present, the fluorescent lamp overwhelming majority is a cathode preheat formula product, and tube cathode is a Primary Component, and fluorescent lamp is lighted without preheating, causes very big damage to filament cathode, shortens the useful life of fluorescent tube.In the CN94226024.4 patent application, a kind of soft-start device that turn-offs is provided, be mainly used in the electronic ceramic device of fluorescent lamp pipeline start up by preheating, it uses piezo-resistance and the series connection of PTC semistor, thermistor control lamp pipeline start up by preheating, piezo-resistance control low-voltage is closed, and key property is contactless, automatic switch, non-wasted work, does not produce heat, has obtained good effect.But when adopting above-mentioned device to make the fluorescent lamp pipeline start up by preheating, owing to be the temperature resistance characteristic of utilizing PTC thermistor uniqueness, promptly the continuous rising resistance along with thermistor body temperature becomes very big, thereby turn-offs preheat curent, plays the effect of tube cathode preheating.And find that in practice constantly raising at PTC thermistor body temperature reaches this process of preheat curent of turn-offing, fluorescent tube has produced glow discharge, fails to reach the best pre-heat effect of fluorescent lamp.

Summary of the invention

The object of the present invention is to provide a kind of fluorescent lamp preheating starter that can instantaneously automatically shut down.

The objective of the invention is and can realize by following technical measures:

A pole-face of pressure-sensitive is welded with indeformable electrode, another pole-face is welded with the thermal deformation electrode, indeformable electrode is fastened on seal wire of stem stem, another seal wire of the contact of thermal deformation electrode and stem stem contacts, glass bulb directly is connected with stem stem, as welding, charge into inert gas by after vacuumizing, constitute the closed type starter.

A pole-face of pressure-sensitive is welded with indeformable electrode, another pole-face is welded with the thermal deformation electrode, indeformable electrode is fastened on the seal wire of device support, and the contact of thermal deformation electrode contacts with another seal wire of device support, constitutes exposed type starter.

Embodiment

As shown in Figure 1, a pole-face of pressure-sensitive 6 is welded with indeformable electrode 7, another pole-face is welded with thermal deformation electrode 5, the other end of indeformable electrode 7 is fixedly connected on the seal wire 4 of stem stem 2, the other end contact of thermal deformation electrode 5 contacts with another seal wire 3 of stem stem 2, the sealing of shell is realized by the welding of glass shell 1 with stem stem loudspeaker limit 10, vacuumizes and charge into certain inert gas (as argon gas), becomes the closed type starter.Lead-in

Fluorescent tube needs high voltage startup, and filament pre-heating can improve useful life, and after the fluorescent tube operate as normal, tube voltage is generally tens volts to more than 100 volts.Among the present invention, because the phenomenon that has temporary transient heat to produce in pressure-sensitive pressure-sensitive change resistance characteristic and the current lead-through process, when the lamp power supply is put in order in connection, be defeated by lamp tube current at first by filament and pressure-sensitive, because pressure-sensitive conducting voltage is located at the conducting voltage less than fluorescent tube, at this moment filament will produce the heat preheating, and pressure-sensitive also produce heat, and heat passed to the thermal deformation electrode rapidly, and the seal wire of stem stem is left in the contact of thermal deformation electrode, and at this moment voltage all puts on lamp tube ends, make the rapid conducting of fluorescent tube and operate as normal, the pipe pressure ratio is lower after the lamp works, and pressure-sensitive quits work, and does not therefore have power consumption.

In view of the thermal deformation electrode contacts of pressure-sensitive connection breaks away from stem stem seal wire contact a progressive formation is arranged, in this process, high-voltage contact air when disconnecting is ionized burning and produces electric arc, and influencing useful life of relevant contacts, the present invention takes sealed structure, vacuumizes and pour inert gas, under the condition of vacuum, owing to lost the condition of burning, just be difficult for producing electric arc, thereby guaranteed the reliable use of starter contact.

The basic principle of Fig. 2, Fig. 3 is the same with Fig. 1, to be Fig. 2 with glass shell 1 and bead 11 directly be connected (as welding) to institute's difference and constitute the closed type starter, and Fig. 3 is that the sealing with shell is realized by the glass-tube 1 and the sealing by fusing (as clamp 13) of bead 12 lead-out wires.

Fig. 4 owing to adopt the bareing structure, carries out thermal deformation and breaks away under atmosphere, be easy to generate arc phenomenon, thereby anti-starting the arc contact (as silver contact) must be adopted in the contact on the contacted seal wire 3 on thermal deformation electrode 5 and the device support 14.Thermal deformation electrode 5 also should adopt the fast thermal deformation sheet metal of deformed movement, thereby improves the reliability and the durability of device.
