In Fuorescent lamp starter without flash of the present invention, the cold resistance value scope of described thermistor is 50-1500 ohm.
Because starter of the present invention adopts a compound temperature-sensitive resistance or by the resistance-type sensory package of thermistor and varistor combination etc., cathode fluorescent tube has enough electron emissivities and discharges to produce high-voltage pulse and build-up of luminance, thereby but fluorescent lamp is issued to steady burning-point in the situation of flicker free; And starter of the present invention is rational in infrastructure, stable and reliable for performance, cost is low and useful life of prolonging lamp tube significantly.
For clearer understanding purpose of the present invention, characteristics and advantage, preferred embodiment of the present invention is elaborated below in conjunction with accompanying drawing.

Fig. 7 is that the starter of Fig. 6 uses the voltage oscillogram that measures in lamp tube ends when a 36W, T8 type fluorescent lamp.
See also shown in 1, can see the Fuorescent lamp starter without flash circuit of first embodiment of the invention among the figure, starter comprises a starter bulb 2 and a resistance-type sensory package, described resistance-type sensory package is a compound temperature-sensitive resistance 3, it is to be bonded by a piezo-resistance 31 and a thermistor 32 with certain breakdown voltage value, and in parallel with starter bulb 2.The breakdown voltage value of described metal oxide varistor 31 can select for use scope between the 40-400 volt, and the cold resistance value scope of described thermistor 32 is 50-1500 ohm.The characteristic of compound temperature-sensitive resistance 3 is consistent with thermistor, when promptly adding thereon voltage and surpassing the puncture voltage of varistor 31, just there is electric current to pass through thermistor 32, simultaneously electric current flows through piezo-resistance and the heat that produces conducts immediately to thermistor, the rapid temperature that makes thermistor 32 that rises of resistance value of thermistor is risen, along with the rising of temperature, the resistance value of thermistor 32 also rises rapidly.Adopt compound temperature-sensitive resistance 3 except the temperature that makes thermistor 32 raises rapidly, also make the temperature rise of piezo-resistance 31 itself slack-off, thereby, the sensitivity of thermistor and the reliability of piezo-resistance can be improved.
Above-mentioned starter is inserted on two filament A, the B points or bipod by the fluorescent lamp tube of Inductive ballast ballast power supply, after fluorescent lamp power supply is connected, starter bulb 2 glow discharges, moving plate closure and tripping, produce a moment induction high pressure, the composite thermistor 3 in parallel with starter bulb 2 can make the size of high pressure be controlled, select the electrical quantity of suitable composite thermistor 3 for different fluorescent tube models, power and supply power voltage, make its magnitude of voltage not reach the puncture voltage of fluorescent tube, thereby fluorescent tube can not puncture luminously, promptly can not glimmer.After repeatedly circulating, tube cathode has obtained enough preheatings on the one hand, and the resistance value of composite thermistor 3 raises rapidly owing to be heated on the other hand, and the induced voltage that is added on the fluorescent tube is risen, at this moment fluorescent tube just punctures and enters normal burning-point, has realized the startup of fluorescent lamp flicker free.The tube voltage drop of fluorescent tube is lower after startup, generally is the puncture voltage that is lower than varistor 31.Therefore at this moment no current passes through, and can not produce power consumption.Simultaneously, therefore play and eliminate the effect of disturbing, needn't resemble and connect one the prior art and eliminate interference capacitors because varistor 31 has the capacitance of hundreds of picofarads.

See also Fig. 6 and shown in Figure 7, as a comparative example, adopt same 36W, T8 type fluorescent lamp operation circuit shown in the figure but use the starter of the capacitor C1 of prior art, after connecting fluorescent lamp power supply from the two ends actual measurement of fluorescent tube to voltage waveform.Can see that from Fig. 7 four induction high-voltage pulses are arranged, its amplitude is more than 700 volts, and this high pressure can make the fluorescent tube of cold negative electrode puncture, and produces flicker.First three high-voltage pulse is that three flickers have taken place among the figure, and fluorescent tube just advances the stable discharge lighting point of people behind the 4th high positive pulse.
See also shown in Figure 2ly, it is the igniter circuitry figure of second embodiment of the invention, and described resistance-type sensory package is a thermistor 4 and a varistor 5, and described thermistor 4 back of connecting with varistor 5 is in parallel with starter bulb 1.The resistance-type sensory package of this starter can be regarded as with the varistor 5 of a serial connection and the composite type heat sensitive resistor that thermistor 4 replaces among Fig. 1, can reach the requirement of flicker free equally, but varistor requires to have higher shock-resistant ability.
See also shown in Figure 3, be the igniter circuitry figure of third embodiment of the invention, described resistance-type sensory package is only used a varistor 6, and described varistor 6 is in parallel with starter bulb 2, with the auspicious requirement that reaches flicker free, but the scope of the fluorescent tube of starter adaptation at this moment is narrower.
See also shown in Figure 4ly, be the igniter circuitry figure of fourth embodiment of the invention, described resistance-type sensory package is only used a thermistor 7, and described thermistor 7 is in parallel with starter bulb 2, but wants consumed power at the thermistor of operate as normal.
