A plurality of embodiment of the present invention will be described in conjunction with the accompanying drawings, wherein:
Fig. 1 is the schematic block diagram that is used to control the electric ballast of two gaseous discharge lamps,
Fig. 2 is the heater chain that is used for two gaseous discharge lamps.
Ballast V shown in Figure 1 is used to operate two gaseous discharge lamp L1, the L2 that two filament W1a, W1b, W2a and W2b are respectively arranged.
In order to produce the operating voltage of lamp L1, L2, line voltage by rectifier 1 by rectification and in chopper circuit by copped wave.Inverter 3 produces the alternating voltage that is supplied to resonance series loop 4 thus.The voltage that reduces on the electric capacity in resonance series loop 4 is supplied to lamp L1, L2 as operating voltage.
A program transmitter that is connected with bus 14 is determined the beginning of the warm-up phase of lamp L1, L2.For this reason, it sends commencing signal at frame 8.Frame 8 produces and is used for the filament W1 of lamp L and filament wattage or the heater current of W2.It is constant that filament wattage or heater current keep in warm-up phase.Filament wattage or heater current are supplied to lamp L1, L2 by frame 6, and this frame comprises that filament voltage limits mechanism.Need to limit filament voltage for example to avoid the transverse discharge between each independent sector of filament.The heater current of " cold " filament W1b, W2b of flowing through produces voltage drop on this common resistance R 5, this voltage drop is transferred to heater current measuring mechanism 7.In addition, extract voltage out on two voltage divider R1/R2 and R3/R4, this voltage is the yardstick that is used for the filament voltage on corresponding " cold " filament W1b, W2b.This voltage is supplied to filament voltage measuring mechanism 9.
Measured value by heater current measuring mechanism 7 and 9 continuous measurements of filament voltage measuring mechanism is transferred to memory 15.This memory 15 is controlled by program transmitter 14, definitely says so control, that is, two of warm-up phase in succession the measured value that is used for heater current and filament voltage in the moment be stored.The measured value of being stored that is used for heater current and filament voltage is sent to from memory 15 asks merchant's device 10, asks merchant's device 10 therefrom to calculate cold resistance and the thermal resistance of filament W1b, W2b.These values are by asking merchant's device 10 to continue to be sent to difference generator 11, and difference generator 11 is therefrom calculated resistance difference.
Associated ground will point out that these frames among Fig. 1 not necessarily must be realized by hardware.On the contrary, the function of a frame also can realize by the corresponding software in the processor.The block diagram of Fig. 1 should only be used for better understanding.
Heater chain shown in Figure 2 is drafted and is exclusively used in the operation that utilizes two gaseous discharge lamp L1, L2.It is roughly corresponding to the frame among Fig. 18.In the case, it can be a heater chain, and it wherein can determine lamp type or some running parameter according to the filament parameter from the filament of direct current supply voltage (for example Vbus) beginning by a gaseous discharge lamp of dc dc converter preheating.Circuit uses inverter work, and this inverter comprises elementary winding T1, beat switch S and resistance R 4 of filament transformer T.These three element connected in series." heat " end of elementary winding T1 is positioned on the bus voltage UBus that is provided by bus, and the cold junction ground connection of resistance R 4.Switch S is sent beat by a control circuit H.The latter is corresponding to a microprocessor P.Microprocessor P obtains control command from bus.
Filament transformer T has three secondary winding T2, T3 and T4.Each secondary winding links to each other with a rectifier circuit.The rectifier circuit that is used for secondary winding T2 is made of a diode B1 and a capacitor C 1.The rectifier circuit that is used for secondary winding T3 is made of a diode D3 and a capacitor C 3.The rectifier circuit that is used for secondary winding T4 is made of a diode D4 and a capacitor C 4.
Inverter is from producing alternating voltage by direct voltage that bus provided, this alternating voltage by above-mentioned rectifier circuit by rectification.Capacitor C 1, C3 and C4 are used for consequent chopping direct voltage is carried out copped wave.The size of direct voltage can be affected by beat ratio and/or the beat frequency that changes switch S.
" heat " the filament W1a and the W2a that are used to heat two lamp L1 and L2 by the direct voltage of the coupling of the rectifier circuit on secondary winding T3 and T4 output." cold " filament W1b and W2b are switched on jointly by secondary winding T2.For this reason, with the rectifier circuit that comprises diode D1 and capacitor C 1 another rectifier circuit in parallel, it comprises a diode D2 and a capacitor C 2.A voltage divider is respectively arranged on two rectifier circuit D1/C1 and D2/C2.One of them voltage divider is made of resistance R 1 and R2.Second voltage divider is made of resistance R 4 and R5.From the node coupling output measuring-signal of two voltage dividers, this measuring-signal is transferred to control circuit H.Measuring-signal is the yardstick that is used for the filament voltage on two " cold " filament W1b and W2b.The electric current of above-mentioned two filaments of process is jointly through a measuring resistance R3.This causes voltage drop on this measuring resistance R3, this voltage drop is continued to be transferred to microprocessor P as measuring-signal and is the yardstick of total current.
After also can moving to measuring resistance R3 to resistance R 4 and R5, shown in dotted line.Resistance is represented with R4 ' and R5 ' at this.
Control circuit H and microprocessor P are used for the measuring-signal of filament voltage jointly and are used for the measuring-signal formation filament resistance of total current.Filament resistance when warm-up phase begins is stored as cold resistance.Having crossed the filament resistance behind the certain hour in warm-up phase is stored as thermal resistance.Constitute resistance difference and compare by thermal resistance and cold resistance, so that determine the type of two lamp L1 and L2 with the value of standard scale.
Be noted that " cold " filament W1b and W2b realize the obvious simplification of circuit by unique secondary winding T2 energising.If with the lamp of this heater chain operation more than two, then this system can keep, and promptly " cold " filament is only by a secondary winding power supply.But other " cold " filament must be provided with an independently rectifier for each.
The characteristics of this circuit are, can propose strict demand about coupling coefficient and voltage strength to circuit, and not about the measurement that may need and the shortcoming of thus obtained message context.Total current by measuring " cold " filament is also measured two filament voltages, can determine the resistance of the filament of two parallel connections.
In addition, filament breaking can followingly be determined.Suppose filament W1b fracture.If inverter is switched on and outage again subsequently, and measures filament voltage after outage, then show following situation.Voltage on voltage divider R1/R2 is kept for a long time, because the time of occurrence constant, it is obtained by product (R1+R2) * C1.And the voltage on voltage divider R4/R5 is decayed fast, because applicable time constant Rhot * C2 here.Rhot is more many greatly than (R1+R2).
If one of filament W1b, W2b fracture is found in the filament inspection, then the filament resistance of filament breaking does not ask merchant's filament resistance calculation mechanism 10 to reduce by half by utilization shown in Figure 1, this common resistance R 5 thereby same electric current is flowed through again.This also is applicable to the filament more than two monitoring filament breaking generally fully.In the case, the filament resistance of the not disconnected filament of monitoring reduces according to corresponding proportion.
