Embodiment
Referring to Fig. 1, the utility model is the energy-conservation double-tube fluorescent lamp ballast of a kind of low-loss, include iron core 1, electric capacity (not shown) and coil 2, wherein iron core 1 is to adopt two E type silicon steel sheets (referring to Fig. 2) closed assembly structures of butt joint relatively, is respectively equipped with a coil L on three columns of the III type closed assembly structure of the same iron core of its formation 1, L 2And L 3(referring to Fig. 3), wherein L 1, L 2Be inductance coil, L 3Be the preheating filament coil.These three coils all have mutual inductance, L each other 1, L 2Between adopt weak coupling, coupling coefficient is about 0.5.And be respectively equipped with adjustable air gap in three columns centres of iron core of this III type closed assembly structure that forms by the butt joint of two E shape silicon steel sheets, and the height of these three iron core air gaps is different: coil L wherein 1The iron core air gap height that is centered on is 0.35-0.55mm, and coil L 2And L 3The iron core air gap height that is centered on is 0.15-0.25mm.The coiling parameter of these three coils is: coil turn L 1: 1100-1300T, L 2: 1100-1350T, L 3: 50-150T, line directly is: φ 0.31-0.35.
Insert the electrical schematic diagram that is connected, wherein coil L referring to the utility model shown in Figure 4 with the double tube fluorescent lamp pipe 1, L 2By one of them fluorescent tube R 1After the filament of one side is played a reversed role and is connected, again with capacitor C 1Be in series this capacitor C 1The other end be connected on another fluorescent tube R 2An end of a side lamp silk, this fluorescent tube R 2Another termination power V of this side lamp silk, the other end wiring circle L of power supply V 1, and by this series loop by these two fluorescent tubes of power supply voltage supplying this group filament electric current; Above-mentioned two fluorescent tube R 1, R 2The two ends of opposite side filament then be after its parallel connection, to be connected on coil L respectively 3Two ends, by coil L 3Supply with the preheat curent of this group filament of these two fluorescent tubes; Capacitor C 2Then be connected across fluorescent tube R 1The two ends filament between, and the one end is to be connected coil L 2Tap on.
Introduce working mechanism of the present utility model below: coil L wherein 1Be mainly used in current limliting, L 2C 2Branch road has capacitive impedance, is mainly used in to start the power factor (PF) of lighting fluorescent lamp and proofreading and correct place in circuit.Because coil L 1Be inductive impedance, and L 2C 2Branch road is capacitive impedance, like this in energized just and the moment of fluorescent lamp when unignited, at these two fluorescent tube R 1, R 2The left end filament on obtained the voltage more much higher (referring to Fig. 4) than supply voltage, this voltage is exactly to start the voltage light fluorescent lamp.Because the starting resistor of fluorescent lamp is very high, and fluorescent tube is had damage.In order to reduce the starting resistor of fluorescent lamp, except taking conventional preheating filament, beyond metal shade ground connection or connecting to neutral measure near the lamp tube wall, the utility model is at above-mentioned coil L 1, L 2Be provided with capacitor C in the series loop 1, be used for further reducing the required starting resistor of this double tube fluorescent lamp and repeat keep-alive voltage.
In addition, the utility model has also taked the sequence starting mode to light fluorescent lamp.Its concrete start-up course is such: when fluorescent lamp is unignited, there is the ion of primary ionization in the fluorescent tube, and when rigidly connecting energize, fluorescent tube R 2In very little townsend discharge electric current is arranged, its tube voltage drop is very low.Because C 1Capacitive reactance very big, the starting resistor overwhelming majority that this moment, ballast offered fluorescent lamp drops to capacitor C 1On, as long as in capacitor C 1On voltage reach fluorescent tube R 1Starting voltage, fluorescent lamp R 1Just at first produce glow discharge, along with being heated very soon of filament, fluorescent lamp R 1Carry out the transition to arc discharge also very soon from glow discharge.At this moment, be added in another fluorescent lamp R 2On terminal voltage be enough to make fluorescent lamp R 2Startup is lighted.So, in fluorescent lamp starting process, R all the time 1Elder generation's starter is only R then 2Starter.This sequence starting mode greatly reduces two lamps series connection required starting resistor and repeat firing voltage when using.The utility model is in the process of sequence starting fluorescent lamp, there is not high-tension impact, do not have the instantaneous burst intensification of filament yet, when the damage that fluorescent tube is subjected to when starting starts fluorescent lamp than other modes the suffered damage of fluorescent tube all little, help prolonging useful life of fluorescent tube.
Moreover, the coil L in the utility model 1, L 2Inductance value all the winding inductance quantity than inductance type ballast is little, flowing through coil L 1, L 2Electric current also littler than the inductance type ballast, the magnetic potential of this ballast, magnetic flux are equally all little than inductance type ballast, therefore, the utility model can reduce the active loss of ballast, reduce the quantity of copper consumption and use silicon steel sheet, both economized on electricity, save non-ferrous metal, also reduced production cost.
It is some that the utility model is manufactured experimently out sample, and adopt described place in circuit and adopt two general inductance type ballast places in circuit that the 30W double tube fluorescent lamp has been carried out the illumination performance contrast test.From the contrast of test data as seen:
1, in supply voltage is the whole working range of 195-240V with under the identical condition of two groups of fluorescent lights output, the input active power of the place in circuit of the present utility model all input active power than inductance type ballast place in circuit is little, and along with the rising of supply voltage, the more remarkable effect of the utility model saving input active power.When the 220V rated voltage, the utility model can be saved active power 6.8W, promptly reduces the active loss of an inductance type ballast, therefore, uses the utility model and uses two inductance type ballasts to compare, and can reduce the active loss 50% of ballast.
2, in supply voltage is the whole working range of 195-240V, place in circuit power factor (PF) of the present utility model is all than the power factor (PF) height of inductance type ballast place in circuit.When the 220V rated voltage, the power factor (PF) of inductance type ballast place in circuit is 0.45, the power factor (PF) of the utility model place in circuit is 0.9, therefore, use the utility model can save reactive power 115Var, save the active loss 11.5Var (getting the economic equivalent 0.1W/Var of reactive power compensation) of circuit.
3, in supply voltage is the working range of 195-240V, place in circuit input current of the present utility model all reduces 50% than the input current of inductance type ballast place in circuit, therefore, when using the utility model, user's supply transformer can double the power supply capacity of fluorescent lamp load.
Sum up above-mentioned contrast test, use the utility model that the double tube fluorescent lamp of two 30W is carried out ballast, every circuit can be saved active power 18.3W altogether, promptly saves active loss 20%, saves reactive loss 80%.
