Embodiment
Fig. 1 schematically illustrates an embodiment of the invention.Circuit structure shown in Figure 1 is the part of electric ballast and a plurality of controllable switch S 1-S4 that comprise DC/AC inverter, and their wirings are linked to be a full-bridge.As switch S 1-S4, preferably adopt field-effect transistor.
Commutating voltage Ubus is applied on the full-bridge, and this commutating voltage comes from the suitable direct voltage source of the respective electronic ballast that has adopted this circuit structure.Direct voltage Ubus for example can produce by utilizing the line voltage that is applied by the assembly conversion of going radio interference element and rectifier to constitute.But, perhaps also can adopt any other direct voltage source.
In the electric bridge shunt of full-bridge circuit shown in Figure 1 (full-bridge), be provided with gaseous discharge lamp EL, especially high-voltage gas discharging light to be controlled.Circuit structure shown in Figure 1 is particularly useful for the very high metal halogen high-voltage gas discharging light of lighting voltage of action need.The difference of high-voltage gas discharging light and low-pressure gaseous discharge lamp is that especially it needs higher lighting voltage and elevated pressures occurs in its less lamp body.In addition, high-voltage gas discharging light also has higher brightness.
The electric bridge of full-bridge shown in Figure 1 links to each other with a series resonant circuit along separate routes, and it comprises an inductance L 1 and a capacitor C 1, and capacitor C 1 acts on the tapping point of inductance L 1 and pass through another controllable switch S 5 in parallel with switch S 4.In addition, be provided with chopper circuit or filter circuit, it has another inductance L 2 and another capacitor C 2, the connection of connecting up as shown in Figure 1 of these elements.Also have a resistance R 1 to be connected with this full-bridge, this resistance is as current measurement resistance (parallel resistance).
Voltage divider R2, R3 are used to measure input voltage and as mentioned above, resistance R 1 is used to measure lamp current.
In addition, Fig. 1 illustrates a central control circuit 1, and central control circuit 1 is powered by supply power voltage device VDD.Control circuit 1 can be an integrated circuit, especially is designed to application-specific integrated circuit (ASIC) (ASIC) or microprocessor (or it is compound).
The control of the switch S 1-S4 of full-bridge and switch S 5 is undertaken by the terminal A1-A5 that links to each other with transistor gate of control circuit 1.By other measurement terminal M1, M2, can measure modulating voltage and lamp current respectively.
Comprising that the above-mentioned series resonant circuit of inductance L 1 and capacitor C 1 and another capacitor C 2 are united is used for especially lighting high-voltage gas discharging light EL.For this reason, excitation series resonant circuit resonance is promptly to a lamp supply frequency corresponding to resonance frequency (or its many times).The excitation of resonant circuit preferably realizes by alternately connecting switch S 1 and S2.
After lighting, start the normal running of this lamp.This full-bridge that comprises controllable switch S 1-S4 is operated in normal running by known mode own, two electric bridge diagonal that promptly comprise switch S 1 and S4 or S2 and S3 are alternately devoted oneself to work and releasing work, and therefore two cornerwise respective switch of electric bridge are replaced in other words break-make complementally.
At this moment, the electric bridge diagonal that is started is made of a high-frequency impulse switch and a low-frequency pulse switch.Preferred S1 and S2 are the high-frequency impulse switches, and S3 and S4 are the low-frequency pulse switches.
The break-make of switch S 1-S4 realizes by the high-frequency pulsed width modulation control signal of control circuit 1 that preferably this signal is filtered by the filter circuit or the chopper circuit that are made of element L2 and C2, thereby has only linear current mean value on gaseous discharge lamp EL.
Therefore, can control the power of supplying with lamp EL, under modulating voltage of considering to measure and lamp current situation, be adjusted in other words by measurement terminal M1, M2 by pulse-width modulation control signal.
The identification of lamp EL is not subjected to the constraint of full-bridge circuit, is not subjected to the constraint of described method of operation yet.For example also can select half-bridge circuit (switch that comprises the complementary commutator pulse of two polyphones) to come operating light EL.Identification is not subjected to the constraint of the mode of operation of lamp EL yet.For example, as the alternative of the said method that utilizes the low frequency rectangular voltage, also can select high-frequency operation.In high-frequency operation, for example can select a half-bridge circuit as circuit structure.Two switches of this half-bridge circuit are alternately applied pulse.In this structure, lamp EL also can be placed in this series resonant circuit that is made of at least one inductance and at least one electric capacity.After lamp EL lights, it can also be operated with high-frequency ac voltage, this high-frequency alternating current is pressed in this series resonant circuit because of resonant excitation alternately applies pulse to two switches of half-bridge circuit and produces, promptly two switches are controlled with the frequency corresponding to resonance frequency of this lamp (or its many times, harmonic wave).In order to reach resonant excitation, this frequency is only just much of that near resonance frequency.
Fig. 2 represents the voltage/current indicatrix K1 of 70 watts of high-voltage gas discharging lights.
When low current value, shown U/I indicatrix at first illustrates the first area 11 with negative resistance slope as everyone knows, and promptly up to commutation smallest point 13, voltage increases and reduces along with electric current.Subsequently, in second area 12, the voltage of high-voltage gas discharging light increases and increases along with electric current.
In second area 12, resistance slope just becomes again.Be exactly in second area 12, promptly be arranged in increase branch, so that guarantee stable lamp operation at the point of normal operation N1 of high-voltage gas discharging light EL.
In other words, near point of normal operation N1, the slope of the voltage/current indicatrix of high-voltage gas discharging light is for just.If at first reduce lamp current, then modulating voltage reduces.This performance exists always, up to commutation smallest point 13.
If give this 70 watts of high-voltage gas discharging light supplies 0 watt of power now, then the corresponding operating point N1 of this lamp is positioned at the U/I indicatrix zone 12 with positive resistance slope.
In addition, Fig. 3 also illustrates the U/I indicatrix K2 of 150 watts of high-voltage gas discharging lights.
If these 150 watts of lamps are operated with above-mentioned 70 watts of power that are suitable for 70 watts of lamps, then for this circuit structure operating point N2 appears.Because the indicatrix K2 of integral shift, so this new operating point N2 has negative resistance slope.
Now, the present invention utilizes the following fact, that is, the point of normal operation of high-voltage gas discharging light is selected in the increase branch 12 of U/I indicatrix.According to the present invention, positive and negative and/or big or small from the slope of the U/I indicatrix on operating point N1 and N2 can infer whether this used high-voltage gas discharging light EL operates with suitable power.
In other words, the present invention proposes a kind of difference measurement of U/I indicatrix.Slope positive and negative and/or big or small that this can be used to measure at operating point the U/I indicatrix adjusts the running parameter that is used for operating light so that (for example contrast by table) again thus.
According to the present invention, can operate many lamp ballasts of different lamp type and can so discern continuous high-voltage gas discharging light, that is, directly or indirectly obtain the slope of U/I indicatrix and check that it is positive and negative at operating point.Slope absolute value is preferably unessential, derives the positive and negative of slope as long as can measure according to direct or indirect U/I.
If the slope of obtaining is for negative, then the operating point of this lamp is positioned at zone 11, and in this zone, voltage increases with electric current and reduces.Can infer that thus lamp EL is with very little power work.And if the slope obtained for just, then the operating point of this lamp is positioned at the zone 12 that lamp current and modulating voltage increase simultaneously, this means suitable or suitable power supply.
Fig. 4 represents how lamp ballast more than discerns continuous high-voltage gas discharging light its wattage in other words.
Suppose that many lamp ballasts can operate the lamp that for example has 70 watts the first power P min or for example have 150 watts the second bigger power P max.
In the first method step S1, after lighting, give the high-voltage gas discharging light EL supply that links to each other smaller power by corresponding control switch S1-S4.
Subsequently, the operating point N1 in that S2 obtains this lamp promptly measures lamp current and modulating voltage.The measurement of this lamp parameter is for example undertaken by above-mentioned measurement terminal M1, the M2 of control circuit 1.
The lamp current of directly or indirectly measuring, occur when the supply first power P min and the value of modulating voltage are stored in next step S3 in the memory cell 5 of control circuit 1, so that can obtain subsequently.
The power that is produced at the S4 full-bridge is reduced subsequently, thereby the current average that is added on the high-voltage gas discharging light EL reduces equally.The power that this produced for example reduces maximum 10%.
In order to determine new operating point N1 ', redeterminate lamp current and modulating voltage and be stored in the memory cell 5 at S6 at S5.
The slope Δ of the voltage/current indicatrix between operating point N1 and N1 ' of the high-voltage gas discharging light that links to each other calculates by following formula at S7 subsequently:
Δ＝(V1-V1’)/(I1-I1’)
If for just, then can infer that at S9 the high-voltage gas discharging light that is connected with this electric ballast has rated power Pmin at this slope Δ of S8, wherein this ballast is operated this lamp with this power P min.
In addition or as an alternative, also can estimate the size of slope.
If not, then learn thus that at S9 ' ballast or control circuit 1 continuous light fixture has rated power Pmax and comes work with this power P max.
Replacement is in S7 slope calculations Δ or resistance slope and obtain the positive and negative of slope Δ at S8 subsequently, perhaps can only demand and go on business the positive and negative of (V1-V1 '), because this is poor (I1-I1 ') itself just remain.
This method also can be used for such ballast, and this ballast can provide more than two power outputs.Many lamp ballasts for example can be provided for operating the lamp with 3 different rated power P1, P2 and P3, wherein P1＜P2＜P3.
In the case, ballast also can so be discerned the wattage of continuous lamp, is repeated to carry out with reference to the described method of Fig. 4.For this reason, at first so carry out the recognition methods of Fig. 4, promptly this gaseous discharge lamp is with minimum power P1 operation, referring to the step S11 of Fig. 5.
To similar among first embodiment,, finding out on the operating point of this low wattage P1 whether lamp has had positive slope in other words in the U/I indicatrix zone of positive resistance slope at S12.If this slope then can be inferred rated power P1 at gaseous discharge lamp at S13 for just.
If not, then can get rid of this power P 1, thereby only also possible rated power P2 and P3 are selective.Circulation adopts recognition methods to mean, now with power P 2 operations, and whether checks resistance slope now for just at S14 at S13 ' lamp, and this should infer rated power P2 or P3 at S15, S15 '.
Do not need must be when each lamp starts identification light.This operating means also can be stored the relevant therewith information from the lamp identification of once carrying out in memory.This memory can be integrated in the control circuit 1, but also externally (in operating means or at least in illuminator), wherein control circuit 1 can be visited it.After finishing the identification of lamp, control circuit 1 can be stored the information of the lamp running parameter that will select about the lamp type of being discerned or according to recognition result in memory.This information can be inquired from memory in resetting process.Storage brings following benefit about the information of the lamp type discerned, that is, needn't discern when each lamp starts.For example can only when for the first time operating means being devoted oneself to work, carry out the identification of lamp.Also have following possibility, that is, the identification of lamp type can more bring startup by sending to change modulating signal or identify lamp.This is for example by taking off at work that lamp carries out or sending signal by the external world and carry out.The external world sends signal and for example can realize by repeating the break-make electrical network or instruct by the external control of sending through existing interface.Memory this moment is nonvolatile storage preferably, and it is also available in operating means outage back.As memory, also can adopt such fuse, it can fuse in order to signal certain lamp type of expression.
For example, consider that indicatrix K1, K2 shown in Figure 3 can see advantage of the present invention.Indicatrix K1, K2 describe the relevant lamp voltage change curve of lamp current with two lamps that are used for respectively having 70 watts or 150 watts rated power.Equivalent resistance 118 or 110 ohm occur at each operating point N1 and N2, thereby in fact may obscure two kinds of lamps easily according to the identification of prior art.And, can clearly distinguish two kinds of lamp type by the lamp type identification based on U/I indicatrix slope according to the present invention.
Another advantage of the present invention is based on reaching and the temperature effect of lamp or the irrelevance of lamp aging phenomenon by this method.Because needn't compare the regulation list of values of absolute value and the lamp type that is used to stipulate for identification light, but the operating point of only estimating in regulation makes the slope of current/voltage indicatrix, so that whether the current/voltage indicatrix of lamp has been shifted because of variations in temperature or lamp are aging is inessential.And the slope of the current/voltage indicatrix of this lamp when such variations in temperature or lamp only change when aging with the degree of ignoring.
