In prior art, in the application of compatible electronic ballast or the most compatible inductance and electric ballast, application
The switching tube that LED drives in the electronic control circuit of lighting often uses frequency detection circuit to drive, such as accompanying drawing 1 institute
Show.In FIG, mains electricity is input to electric ballast 110, electric ballast 110 inversion output high voltage and electric current,
General work frequency is more than 20kHz, is input to electronic control circuit 120.Inside electronic control circuit 120, high-frequency alternating current
Pressure and electric current enter rectifier circuit 122 through filament analog circuit 121, then export suitable electricity through LED drive circuit 123
Stream.LED drive circuit 123 is including at least a switching tube S, such as pliotron, field effect transistor, IGBT or other electronics
Switch, the driving signal of switching tube S is from frequency detection circuit 124, and the input of frequency detection circuit 124 is simulated from filament
Circuit between circuit 121 and rectifier circuit 122, output is then in order to drive switching tube S.Frequency detection circuit 124 often sets
Being calculated as, when incoming frequency is civil power low frequency, connect such as fluorescent tube is Inductive ballast, then it is output as low level, it is impossible to drive
Dynamic switching tube S；When incoming frequency is high frequency, connect such as fluorescent tube is electric ballast, then it is output as high level, switching tube
S turns on.The circuit diagram of the frequency detection circuit 124 shown in Fig. 1 as shown in Figure 2, in fig. 2, before rectifier circuit 122
Voltage, through resistance R10 and electric capacity C10, is on the one hand connected to diode D10, on the other hand connects stabilivolt Vz0, D10 output
Being connected to ground by resistance R20 and electric capacity C20, the voltage above R20 and C20 is as exporting in order to control the dynamic of power switch
Make.Owing to the voltage before rectifier circuit 122 is exchange, alternating voltage produces certain electric current, this electric current by electric capacity C10
Size and C10 capacitance, alternating voltage amplitude and frequency dependence, when alternating voltage is power frequency component, due to the low frequency of C10
Capacitive reactance is very big, and the electric current flowing through C10 is smaller, and the voltage ratio produced on R20 and C20 through D10 is relatively low, it is impossible to drive
Switching tube；When alternating voltage is high-frequency signal, the capacitive reactance of C10 is smaller, and the electric current flowing through C10 strains greatly mutually, at R20 and
Produce high level above C20, drive switching tube conducting.
From Fig. 1 and Fig. 2, although foregoing circuit can realize driving switching tube S conducting when electric ballast inputs, but
It is that the ballast of some brand intermittent can export high-frequency signal when off, and these high-frequency signals pass through frequency detection circuit
Switching tube S intermittent conduction can be promoted, make the LED light source intermittence in above-mentioned lighting luminous, when having Electronic Control electricity
When the lighting on road works with this type of ballast, after power cutoff, there will be the phenomenon of LED light source flicker in lighting,
Cause being discontented with of user.Although this problem can be solved by increasing delay in frequency detection circuit output, but postpone
Circuit can introduce another one problem, it is simply that when connecting non-preheating type ballast due to the reason of delay circuit, it is impossible in time
Drive switching tube S conducting, cause ballast output overvoltage, increase the risk that LED light source lost efficacy.

Logic glue 325 described in above-described embodiment can be realized, below by multiple different circuit structure
The circuit structure that two of which is different is described in detail by two specific embodiments.
Fig. 4 is the partial circuit schematic diagram of electronic control circuit 320 in an embodiment, as shown in Figure 4, the first resistance
R1, the first electric capacity C1, the first diode D1, the first stabipack and the first stabilivolt Vz form first frequency testing circuit
323, wherein, the first stabipack is made up of the resistance R2 being connected in parallel and electric capacity C2, the first resistance R1, the first electric capacity C1,
One diode D1, the first stabipack are sequentially connected in series to logic glue 325, and the negative pole of the first stabilivolt Vz is connected to
Between first electric capacity C1 and the first diode D1, the positive pole of the first stabilivolt Vz and the first stabipack connect and ground connection；Second
Resistance R1A, the second electric capacity C1A, the second diode D1A, the second stabipack and the second stabilivolt VzA composition second frequency inspection
Slowdown monitoring circuit 324, wherein, the second stabipack is made up of the resistance R2A being connected in parallel and electric capacity C2A, the second resistance R1A, second
Electric capacity C1A, the second diode D1A, the second stabipack are sequentially connected in series to logic glue 325, the second stabilivolt VzA
Negative pole be connected between the second electric capacity C1A and the second diode D1A, the positive pole of the second stabilivolt VzA and the second stabipack
Connect and ground connection；Wherein, the capacitance of the first electric capacity C1 capacitance more than the second electric capacity C1A.PNP type triode switch K1,
NPN type triode switch K2, the 3rd resistance R3, the 4th resistance R4 and feedback resistance Rbf form logic glue 325, its
In, the emitter stage of switch K1 is connected with first frequency testing circuit 323, and the colelctor electrode of switch K1 is connected with on-off circuit 326, opens
The base stage closing K1 passes sequentially through the 4th resistance R4, switch K2 ground connection, and the 3rd resistance R3 is connected in the two ends of switch K1, feedback in parallel

Feedback resistance Rbf feeds back.When electric ballast 310 normally works, the high frequency voltage of electric ballast 310 output is the
Two frequency detection circuits 324 export high level, are directly output to on-off circuit 326 by the 3rd diode D2, make on-off circuit
326 start work；Under the high level of on-off circuit 326 and the effect of feedback resistance Rfb, switch K2 conducting so that switch
K1 emitter stage, to base stage positively biased, switchs K1 saturation conduction, maintains output high level further.When electric ballast 310 enters surely
When surely working, second frequency testing circuit 324 output low level, and first frequency testing circuit 323 keeps high level output,
Under the reversely cut-off protection of the 3rd diode D2, on-off circuit 326 keeps high level output, therefore tends to remain on.
It follows that the startup of on-off circuit 326 needs second frequency testing circuit 324 to export high level signal；Electronics
After ballast 310 steady operation, the high level output lasting due to first frequency testing circuit 323 and feedback resistance Rfb's
Feedback, on-off circuit 326 keeps output high level.When electric ballast 310 turns off, due to first frequency testing circuit 323
High level output, logic glue 325 is not all had to be also at off state, even if now with second frequency testing circuit 324
Electric ballast 310 intermittent output high-frequency signal, owing to the capacitive reactance of the second electric capacity C1A is bigger, resistance R2A and electric capacity C2A
Cannot accumulate enough voltage-driven switch circuit 326 above so that interface logic unit 325 is held off, 325 export low electricity
Flat, i.e. it is held off, therefore avoids the shutoff scintillation of the lighting with electronic control circuit 320.
