As illustrated in figure 4f in embodiment, the compatible circuit 1510 includes：Control unit 5562, switch unit 5563 and is adopted Sample unit 5564；The sampling unit 5564 forms sampled voltage according to external drive signal；The switch unit 5563 is in institute The compatible circuit 1510 is disconnected when stating sampled voltage more than preset value the current limiting capacitance 541 is accessed circuit, and in institute The compatible circuit 1510 is connected when stating sampled voltage less than preset value；Described control unit 5562 is used for according to sampling electricity The voltage-controlled cut-off and conducting for making the switch unit 5563.

Specifically, described control unit 5562 includes power branch, IC chip 4561；Second resistance 4563；Second capacitance 4565；Triode 4567；The both ends of the current limiting capacitance 541 are electrically connected in the both ends of the power branch；The power supply Branch is used to provide the driving power of the IC chip 4561.

The IC chip 4561 is electrically connected between the switch unit 5563 and the power branch, and is electrically connected The collector of the triode 4567, the emitter of the triode 4567 connect one end of the power branch, the triode 4567 base stage and the transmitting interpolar of the triode 4567 are electrically connected with second capacitance 4565, the triode 4567 Base stage be electrically connected one end of the second resistance 4563, the other end of the second resistance 4563 and the triode 4567 Transmitting interpolar be electrically connected the sampling unit 5564.

Next carry out detailed description in conjunction with Fig. 4 F (Fig. 4 F are the topological schematic diagram of ballast compatible circuit 1510 in Fig. 3 C) (electric current of the output of electric ballast work is larger, usually in 200mA or so for the action mechanism of Fig. 3 C schemes；And emergent ballast The electric current that device exports when working is smaller, typically not greater than 50mA)；When LED daylight lamp 500 is powered, MOS switch 4562 is connected.

When applied to electric ballast, since the electric current of electric ballast output is larger (200mA or so), resistance 4564 On sampled voltage it is larger, give capacitance 4565 to charge via resistance 4563, the voltage of capacitance 4565 increases, and reaches triode 4567 Activation threshold value, triode 4567 is connected, and the Vcc terminal voltages of IC chip 4561 are pulled low, and IC chip 4561 does not work at this time, MOS switch 4562 ends；At this moment current limiting capacitance 541 accesses circuit, then discharges via capacitance 541, and the voltage at the ends Vcc rises, Reach the threshold value of setting, IC chip 4561 is started to work, and OUT terminal exports trigger signal, and MOS switch 4562 is connected.At this time by Larger (200mA or so) in the electric current of electric ballast output, the sampled voltage on resistance 4564 is connected compared with triode 4567, IC The Vcc terminal voltages of chip 4561 are dragged down again, and IC chip 4561 does not work at this time, and MOS switch 4562 ends, repeatedly. 4562 periodic conduction and cut-off of MOS switch.

Its VCC terminal voltage of different IC chips is also different, and in the present embodiment, Vcc operating voltages select 21V, charging Time is pulled low the time of (blanking voltage, such as 10V) much larger than Vcc voltage.Thus while the conducting in 4562 period of MOS switch/ Cut-off, the identification range of the remote superman's eye of frequency of conduction and cut-off, so, user is the flicker of imperceptible fluorescent lamp at this time.

In addition, in the present embodiment, capacitance 541 can also flow through LED's by choosing different capacitances to set Electric current.Due to there is capacitance 541 (play and adjust electric current), the electric current of LED is flowed through in adjustment, can reduce electric ballast and make an uproar Sound (electric ballast matches the resonance caused with LED daylight lamp).

When should be in emergency ballast, due to emergency electronic ballast output current it is smaller (<50mA or so), resistance 4564 On sampled voltage it is smaller, give capacitance 4565 to charge via resistance 4563, since the sampled voltage on resistance 4564 is smaller, up to not To the activation threshold value of triode 4567, triode 4567 ends, therefore MOS switch 4562 maintains constant conduction, in this way by capacitance 541 branch bypass.

In the above embodiment, discharge tube DB1 threshold values are between 250V~600V.Preferably, threshold value chooses 250V, 300V, 350V, 400V, 420V, 450V.If the threshold value of discharge tube DB1 conducting is too small, had when being matched with certain ballasts compatible The problem of property, it cannot successfully light LED daylight lamp.Itself main reason is that：When LED daylight lamp is powered, the electronics of some types Ballast does not work normally also, and the discharge tube of LED daylight lamp has been connected (impedance changes at this time), and electric ballast erroneous judgement is negative It is abnormal to carry (LED daylight lamp connected).

①：Due to the presence of capacitance 541 (also referred to as current limiting capacitance), LED current can be made adjustable by selecting suitable parameter Section, improves the efficiency of LED lamp tube.

②：So that LED daylight lamp can compatible electronic ballast and compatible emergency ballast.

③：The big problem of part ballast noise can be reduced, and (electric ballast matches the humorous of initiation with LED daylight lamp It shakes).

④：LED daylight lamp can be successfully lighted when improving electrical network low voltage.

④：The embodiment of ballast compatible circuit 1510 is different, can use the compatible circuit of embodiment as shown in Figure 4 G. Specifically, compatible circuit 5510；Including：Bidirectional triode thyristor 5511, inductance 5512, protective device 5513, bilateral diode 5514, Resistance 5515, capacitance 5516, capacitance 5517, resistance 5518；It is electrical through the ends A behind the 1 end ends electric connection A of bidirectional triode thyristor 5511 One end of 541 (not shown) of capacitance is connected, the other end of bidirectional triode thyristor 5511 is electrically connected the ends a of inductance 5512, inductance 5512 ends b are electrically connected one end of protective device 5513, and the other end of protective device 5513 is electrically connected behind the ends B through the ends B electricity Property be electrically connected 541 (not shown) of capacitance the other end；The triggering end of bidirectional triode thyristor 5511 is electrically connected bilateral diode The other end of 5514 one end, bilateral diode 5514 is electrically connected one end of resistance 5518 and one end of capacitance 5516, capacitance 5516 ends B are electrically connected the ends a of inductance 5512, and the ends b of resistance 5518 are electrically connected one end and the capacitance 5517 of resistance 5515 One end, the other end of resistance 5515 is electrically connected 1 end of bidirectional triode thyristor 5511；The ends b of capacitance 5517 are electrically connected capacitance 5516 ends B and the ends a of inductance 5512.

Next the LED daylight lamp of description Fig. 3 D schemes acts mechanism.

It applies in the occasion of electric ballast, the ac signal of electric ballast work output high frequency flows through capacitance 541。

It applies in the occasion of emergency ballast, if electric current flows through capacitance when emergency ballast output is ac signal 541；If output is DC signal or unidirectional pulse formula (direct current) signal, the capacitance 541 is bypassed；Specifically：After energization When the electric signal be added in the both ends of capacitance 541, capacitance 5517 charges by resistance 5515, and capacitance 5516 passes through resistance 5518 Charge, after continuing for some time, capacitance 5517, capacitance 5516 voltage be gradually increased to be more than bilateral diode 5514 The threshold values of (sometimes referred to as two-way trigger tube), after bilateral diode 5514 triggers, the triggering end of bidirectional triode thyristor 5511 is (sometimes Claim gate pole) constant current is flowed through, bidirectional triode thyristor 5511 is connected, to bypass the capacitance 541.

In above-described embodiment, inductance 5512 has the function of inhibiting current break, the virtual value of electric current also can be improved, in turn The brightness of fluorescent tube can be improved.In addition, inductance have afterflow (the pulse DC electric signal sent out to emergency ballast carries out afterflow, To maintain 5511 constant conduction of bidirectional triode thyristor), the effect of energy storage, the maximized emergency ballast that absorbs exports electricity.

In above-described embodiment, the selected value of Thermal Cutoffs (FU1~4) preferably chooses 125 ° between 100 °~150 ° Or 130 °.

In above-described embodiment, protective device 5513 can choose Thermal Cutoffs, rated value between 100 °~140 °, compared with 120 ° of good selection.In setting, the rated value that Thermal Cutoffs is chosen is specified less than what Thermal Cutoffs (FU1~4) was chosen Value.Or rated current type fuse is chosen, specified current value chooses 100mA~500mA, and preferably selection 100mA~ 200mA, such as 100mA, 150mA, 200mA etc..Other control units can also be chosen, by the control unit detect temperature or Current information, reaches the threshold value of setting, and trigger protection can (such as fuse the fuse).The protective device 5513 is used in electronics Ballast occasion, bidirectional triode thyristor 5511 cause the high frequency high current that electric ballast exports to flow into inductance 5512 by false triggering (being equivalent at this time, enter by mistake through contingency mode), and start the protective device.Under contingency mode, the electric current of emergency ballast output Typically not greater than 50mA, and under electric ballast pattern, the electric current of electric ballast output is usually in 200mA or so.

In above-described embodiment, the inductance value of inductance 5512 preferably chooses 2mH~10mH, the present embodiment between 2mH~15mH Middle inductance value chooses 8mH.

In other examples, in scheme shown in Fig. 3 D, the compatible circuit of Fig. 4 F can be used.

In other examples, protective device 5513 can be omitted.Also inductance 5512 can be omitted.

As the deformation of the embodiment of the compatible circuit of scheme shown in Fig. 4 G,

①：Resistance 5515 and capacitance 5517 can be omitted, at this moment the b of resistance 5518 is electrically connected the 1 of bidirectional triode thyristor 5511 End.

②：Resistance 5518 and capacitance 5516 are omitted, at this moment the other end of bilateral diode is electrically connected the one of capacitance 5517 End.

Applicant has found the compatible circuit scheme LED straight lamps such as Fig. 4 G in the IS types with certain model, PS in propulsion Type electric ballast has incompatible phenomenon when matching, by further analyzing, the electric ballast output signal of the model In containing DC offset voltage (also referred to as DC component, as shown in figure 5, for certain model electric ballast output signal in contain Have the oscillogram of DC offset voltage), it can charge to the capacitance in compatible circuit, false triggering compatible circuit is caused (to touch The bidirectional triode thyristor of compatible circuit is sent out to trigger compatible circuit), and then the electric ballast of the incompatible model of fluorescent lamp, it is This, further improves the compatible circuit scheme of Fig. 4 G, specifically as shown at figure 4h.

Difference lies in release can component 5519 for parallel connection on capacitance 5516 shown in Fig. 4 H and Fig. 4 G.

Next the mechanism of energy component 5519 is released in description：

IS types, PS types electric ballast at work, since there are DC offset voltage (sometimes referred to as direct currents point for itself Amount), there are bias voltage at the both ends of such bidirectional triode thyristor 5511 (as shown in oblique line with the arrow in Fig. 5)；Direct current biasing electricity Pressure can make capacitance 5516 voltage (through accumulation after a period of time) improve to bilateral diode 5514 activation threshold value, two-way two Pole pipe 5514 is connected, and triggers bidirectional triode thyristor 5511, and then bypass capacitance 541 in Fig. 3 C-E schemes, leads to LED daylight in this way Lamp cisco unity malfunction.For this purpose, the branch circuit parallel connection one in capacitance 5516 releases energy component (such as releasing energy resistance), this releases energy component to let out The energy by the direct current biasing is put, such bilateral diode 5514 will not be triggered, and then bidirectional triode thyristor 5511 will not be by Triggering, to improve the compatibility of LED daylight lamp.

In said program, using release can 5516 accumulation of resistance consumption capacitance energy, make capacitance 5516 voltage will not on The trigger voltage of bilateral diode 5514 is risen to, and then bidirectional triode thyristor 5511 will not be triggered.Improve the compatibility of LED daylight lamp Property.

In above-described embodiment, energy component 5519 is released, energy resistance is released in selection, and resistance value chooses 1K ohm~1M ohm；Preferably Selection, 1K ohm~1000K ohm.The energy release of component 5519 is released caused by electric ballast itself direct current biasing to electricity Outside the energy for holding 5516 chargings, electric leakage of the also releasable bidirectional triode thyristor due to the inconsistent initiation of heated rear both sides equivalent resistance Stream, the energy (electric energy) to charge to capacitance 5516.

In above-described embodiment, the activation threshold value of bilateral diode chooses 10v~100v, preferably chooses, 20v~50v.This In embodiment, the activation threshold value of bilateral diode chooses 32V.

In other examples.As the deformation of Fig. 4 G schemes, energy component is released in the branch circuit parallel connection of capacitance 5517, to let out The energy of 5517 storages is held in electric discharge.

In other examples, the deformation as Fig. 4 G schemes improves the activation threshold value of bilateral diode, such as chooses 50v.In other examples, or will release can component 5519 (such as resistance, the resistance) connect with the bilateral diode newly set The branch circuit parallel connection of the branch of formation and the branch of capacitance 5516 or capacitance 5517, at this moment this new set bilateral diode series connection triggering Threshold value is chosen between 5V~25V.Designing in this way is advantageous in that, when not triggering bilateral diode series connection, releases energy component not It releases the energy of capacitance, can reduce that release can component energy consumption in this way.

It is connected with transistor (such as metal-oxide-semiconductor) switch alternatively, this can also be released to energy component (such as bleeder resistance), the transistor Triggering end link control module, control module samples the input signal of fluorescent tube, to analyze the DC component in input signal；If should DC component is between 0.5~3 times of threshold value of setting, then transistor turns, DC component in the signal of at this moment ballast output More bleeder resistance and the branch for being connected to capacitance, consume the energy of the DC component, improve the compatibility of ballast；If the sampling DC component is more than 3 times of the threshold value set in the signal of the ballast output of signal sampling, then transistor cutoff, at this moment thinks Lamp works are in emergency rating；If DC component is less than the 0.5 of the threshold value of setting in the sampled signal, transistor cutoff is let out Electric discharge resistance does not access capacitive branch.Threshold value chooses a certain value in 5%~50%, i.e. DC component accounts for the signal of ballast output Ratio.

Certainly it also can be used, omit resistance 5515 and capacitance 5517, at this moment the b of resistance 5518 is electrically connected bidirectional triode thyristor 5511 1 end；Or, omitting resistance 5518 and capacitance 5516, at this moment the other end of bilateral diode is electrically connected capacitance 5517 One end.

In the present embodiment, protective device 7513 chooses Thermal Cutoffs, and (100 °~130 ° of the threshold value of selection is preferably selected Take 120 °).Its structure chooses flat boxes shape (cuboid), has 2 pins.Inductance 7512 is matched with Thermal Cutoffs When assembling is with power module, 7512 tail portion magnetic core of inductance and the height of Thermal Cutoffs are substantially concordant；Inductance 7512 is protected with temperature It is smaller than 5mm between dangerous silk, is preferably less than 2mm.If larger in spacing, the triggering precision of Thermal Cutoffs can be influenced.Temperature Degree fuse fixes (e.g., the mode of plug-in unit) in power module, substantially vertical with the surface of power module (pcb board).

In the present embodiment, the inductance value of inductance 7512 chooses 1mH~15mH, and preferable inductance value chooses 2mH~8mH.

In other examples, in order to prevent the weld of power module and lamp plate because rosin joint cause coupling part print Printed circuit board is carbonized and lasting conducting, is arranged between 2 weld pads (also referred to as pad) for connecting the fuse of power module The isolation channel of hollow out increases creepage distance by the isolation channel, and then also continues to arcing after preventing fuse from disconnecting.Isolation channel Shape can be set to ellipse, diamond shape, rectangle etc..In other examples, which can be arranged multiple, at this moment for The intensity of power module (printed circuit board) is not influenced, is not connected between the isolation channel.
