The present invention also relates to a kind of lighting device of applying driver of the present invention.
The explanation of preferred embodiment
Further illustrate the present invention below in conjunction with accompanying drawing.In figure:
Fig. 1 illustrates according to driver of the present invention;
Fig. 2 illustrates the part according to driver of the present invention.
Embodiment below in conjunction with driver describes the present invention.
Fig. 1 illustrates synoptic chart, and Fig. 2 illustrates the especially part of the driver of the lighting apparatus of fluorescent lamp.Fig. 2 especially illustrates the direct lighting equipment control section LD of driver.
The driver of lighting apparatus has inverter, this driver can have at least one ACTIVE CONTROL switch (Q30, Q31), described at least one ACTIVE CONTROL switch is supplied with direct voltage, the resonance output circuit with at least one inductor (Lr) is connected on this ACTIVE CONTROL switch (Q30, Q31), to drive at least one lighting apparatus (lamp), wherein, this ACTIVE CONTROL switch (Q30, Q31) is by coming controlled with the coupling of this output circuit.At least can intervene by additional control circuit (IC) the control of ACTIVE CONTROL switch (Q31).Described coupling can realize by magnetic coupling, especially realizes by secondary winding being coupled to the inductor (CT) of connecting with described output circuit.
Can so realize the control of ACTIVE CONTROL switch (Q31) by additional control circuit (IC), that is, improve the frequency of inverter, and/or shorten the turn-on time of switch (Q31).
For example only in the time that control circuit (IC) has been found fault or found to be different from the mode of operation (preheating, build-up of luminance, lamp failure, replacing lamp) of the normal work of lighting apparatus, control circuit (IC) just can be intervened one of them the initiatively control of clock switch (Q31).
Can in inverter or output circuit, pick up at least one measuring-signal, and control circuit (IC) can detect or monitor this measuring-signal.Control circuit (IC) can be analyzed detected measuring-signal, and determines that accordingly driver is in which kind of mode of operation (preheating, build-up of luminance, lamp failure, replacing lamp, normally work).Control circuit (IC) can be analyzed detected measuring-signal according to determined mode of operation (preheating, build-up of luminance, lamp failure, replacing lamp, normally work).
Control circuit (IC) can be analyzed detected measuring-signal in time, preferably to carry out sampling than the sample frequency of (expectation) inverter frequency higher (at least twice or more than).
Control circuit (IC) can be monitored multiple measuring-signals, wherein, a common interface at control circuit (IC) can be monitored at least two different measuring signals, and this monitoring is to implement according to analysis in time by control circuit (IC).In the time of at least two different measuring signals of the common interface place of control circuit (IC) monitoring, can detect and further process these measuring-signals by means of the inner multiplexer of control circuit (IC).Also can make by this way input be matched with each measuring-signal to be detected (for example, about amplitude or precision).
Control circuit IC for example can be in conjunction with the control frequency that detects inverter about the monitoring of time.Control circuit IC for example can be alternatively or is additionally determined the initiatively time that turns on and off of clock switch (Q31, Q30), and in the time of the turning on and off time point or approach this time point of active clock switch (Q31, Q30), carries out accordingly the monitoring of measuring-signal.Can avoid by this way (preferably by initiatively clock switch (Q31, Q30) of forbidding) may cause the initiatively critical condition (for example, in conjunction with measurement point S1) of clock switch (Q31, Q30) impaired (for example so-called hard switching or capacitance switch).Can postpone the initiatively connection again of clock switch for fear of for example so-called hard switching, the critical transverse current that may occur when avoiding two switches while conductings when inverter in inverter.
But be combined in temporal analysis, for example also can avoid inductor saturated (for example, in conjunction with measurement point S1) under build-up of luminance operating state or normal operating conditions.Saturated for fear of inductor (Lr) under build-up of luminance operating state or normal operating conditions, when detecting that at measurement point S1 namely that moment of critical current is turn-offed initiatively clock switch (Q31) to too high electric current.In this case, initiatively clock switch (Q31) is not based on by controlling with the coupling of output circuit, but turn-offs (disconnection) by the additional control of control circuit (IC).
Control circuit (IC) can testing state conversion, and in the time that this conversion occurs, one of them initiatively control of clock switch (Q31) can be intervened, and/or the analysis (Optimum Matching is in new mode of operation) of detected measuring-signal can be changed.At least can only under some operating state, monitor and reach critical excitation or the instantaneous measuring-signal of working separately, meanwhile under other operating states, not activate this monitoring.
The lamp state of changing (it detects and changes lamp, namely changes lighting apparatus) for example can be detected, send control impuls by control circuit (IC) to active clock switch (Q31) accordingly, make inverter enter pre-hot working.For example also can detect lamp failure (for example filament breaking or rectifying effect) by control circuit (IC) control measurement signal, thereby detect operating state from normal work (wherein, lighting apparatus by inverter with full power operation) and be converted into the operating state of lamp failure.In this case, control circuit (IC) for example, by initiatively clock switch (Q31) disconnection inverter (for example, by the control interface of active clock switch (Q31) is pulled down to ground connection) of forbidding.
During pre-hot working, additional control circuit IC for example can continue to intervene initiatively clock switch Q31, to improve the frequency of inverter and/or shorten turn-on time of switch (Q31).
In the time of conversion operating state, control circuit (IC) is in the control through intervening one of them active clock switch (Q31) after the scheduled time, so that inverter enters another mode of operation.For example, after determining the mode of operation of changing lamp, inverter can enter preheating mode of operation, and after the process scheduled time, inverter just can enter build-up of luminance mode of operation.
But; control circuit (IC) for example also can be according to reaching critical excitation or the monitoring of the instantaneous measuring-signal of working detects; and improve inverter frequency and/or shorten the switch connection time (Q31) by intervening the control of at least one ACTIVE CONTROL switch (Q31) accordingly, thereby protection driver (especially inverter and output circuit) and the lighting apparatus being connected and avoid damaging immediately.
For example can avoid current overload or voltage overload the turn-on time of inverter frequency or shortening switch (Q31) by improving.In the time that counter works also exists critical condition after finishing in other words through the longer time, just can forbid or disconnect inverter by intervention active clock switch (Q31).Control circuit (IC) for example can detect or monitor inverter bottom (below switch Q31 and ground connection between) electric current as measurement point S1, detect or monitoring is upper at lighting apparatus (lamp) or voltage on the node between lighting apparatus (lamp) and inductor (Lr) or capacitor (Cr) as measurement point S2 and the direct voltage (Vdc) that is fed to as measurement point S3.Measure feeding DC on measurement point S3 press (Vdc) can be simultaneously for the power supply (voltage supply) of control circuit (IC).For example, measurement point S1 and S2 can be connected to each other by for example resistor of at least one coupling element or diode, and are monitored on a common input of control circuit (IC).The measurement point that other are possible or the measuring-signal that will detect are for example the voltage of inverter (S4) mid point, the voltage of capacitor Cr or flow through the electric current of lighting apparatus.But additionally can also detect for example rectification input voltage of other measuring-signals, or measuring-signal in circuit of power factor correction (for example flow through circuit of power factor correction switch electric current or flow through the electric current of the storage inductor of circuit of power factor correction).Control circuit (IC) can have output (P1), and it preferably can intervene the control interface of the active clock switch (Q31) of the below of this inverter.
But in a favourable execution mode, this output (P1) also can be simultaneously as input (monitoring input) for control measurement signal.At this, this interface can be used as input the most of the time, only in the time of needs or expectation intervention inverter, is just driven as output, to thereby can intervene initiatively clock switch (Q31).Can pass through by this way combined interface P1(as output/input) direct-detection inverter frequency.
In an alternative embodiment, replace the active clock switch (Q31) of the below of intervening inverter, control circuit also can be intervened the switch of the circuit of power factor correction of upstream.
The direct voltage (Vdc) (being the output voltage of circuit of power factor correction) being for example fed to by reduction can be avoided current overload or voltage overload on inverter.In the time that counter works also exists critical condition after finishing in other words through the longer time, also can forbid or disconnect inverter by forbidding circuit of power factor correction.
ACTIVE CONTROL switch (Q30, Q31) can be bipolar transistor or can be also mos field effect transistor (MOSFET) or insulated gate bipolar transistor (IGBT).Fly-wheel diode (D30, D31) arranges on ACTIVE CONTROL switch (Q30, Q31) inverse parallel ground relatively, to for example allow electric current to flow through in the afterflow stage.
This scheduled time can be determined the duration of warm-up phase.
Lighting apparatus (lamp) can be fluorescent lamp or can be also light-emitting diode (perhaps organic or inorganic has the rectifier that is connected to upstream).
Capacitor (Cr) can be connected with the filament of fluorescent lamp.Thereby in the future the resonance step-up of self-capacitance device (Cr) and inductor (Lr) series circuit is used for preheating and/or build-up of luminance, can obtain in the build-up of luminance stage voltage that is enough to build-up of luminance lighting apparatus thus, and can enough pre-thermal energy be passed to filament at warm-up phase.
But independent heating transformer (Heiztransformator) also can be set, or can obtain heat by the secondary winding of at least one and inductor (Lr) coupling.
Being used for controlling the initiatively magnetic coupling of clock switch (Q30 and Q31) can implement by transformer, and the winding of this transformer can be arranged on annular core.But this magnetic coupling also can directly realize by secondary winding on the inductor (Lr) of resonance output circuit.
Resonance output circuit can comprise at least one coupling capacitor (Cblk1, Cblk2), this coupling capacitor (Cblk1, Cblk2) setting of connecting with the inductor (Lr) of resonance output circuit.Coupling capacitor (Cblk1, Cblk2) also can be divided into two capacitors, and these two capacitors are arranged between direct voltage (Vdc) and ground connection as capacitor voltage divider, and resonance output circuit is connected on the mid point of these two capacitors.
Direct voltage (Vdc) for example can generate by the rectifier (by input voltage vin) being connected in AC network, and active power factor correction circuit (PFC) for example boost chopper formula PFC or valley fill circuit can be set in this rectifier downstream.Circuit of power factor correction can be given at least one buffer condenser C_DC power supply.Valley fill circuit can be by passive valley fill circuit or active valley fill circuit (AVF, Fig. 1 symbol illustrates) or constituting by active and passive valley fill circuit.Initiatively valley fill circuit can be coupled with output circuit or inverter.
For example, but direct voltage (Vdc) also can generate by cell voltage.
Lighting device can use driver of the present invention.
Inverter can be for example flyback (flyback converter of isolation) inverter, full-bridge, half-bridge or push-pull dc-to-ac (push-pull converter).
Control circuit (IC) can have integrated start-up circuit, to can give at least one initiatively clock switch (Q31) transmission starting impulse, thereby excitation inverter is devoted oneself to work it.In the time having applied supply power voltage or replacing lamp detected, control circuit just can generate starting impulse.
