In another exemplary embodiment, because the impedance of human body will lead on electric power loop when human contact's fluorescent tube Equivalent impedance changes, and installation detecting module 2520 can judge whether user contacts by the voltage change on detecting electric power loop Above-mentioned electroshock-proof function equally may be implemented in fluorescent tube.In other words, in the utility model embodiment, detecting module is installed 2520 can judge whether fluorescent tube is properly installed and whether is user through detecting electric signal (including voltage or electric current) The current-carrying part of fluorescent tube is accidentally touched in the case where fluorescent tube is not installed correctly.

5B referring to Figure 1, for according to the circuit diagram of the installation detecting module of the utility model embodiment.Installation is detectd Survey module include switching circuit 2580, detection pulse (pulse) occur module 2540, testing result latch cicuit 2560 and Detect decision circuit 2570.Detect decision circuit 2570 (through switch coupling end 2581 and switching circuit 2580) first peace of coupling Sense terminal 2521 and coupling the second installation sense terminal 2522 are filled, is detectd with the first installation sense terminal 2521 of detecting and the second installation Survey the signal between end 2522.It detects decision circuit 2570 and couples testing result latch cicuit through testing result end 2571 simultaneously 2560, testing result latch cicuit 2560 is sent to will test consequential signal through testing result end 2571.Detect pulse generation Module 2540 couples testing result latch cicuit 2560 by pulse signal output end 2541.Testing result latch cicuit 2560 Testing result is latched according to testing result signal (or testing result signal and pulse signal), end 2561 is latched through testing result and couples Switching circuit 2580, will test result transmission or be reflected into switching circuit 2580.Switching circuit 2580 according to testing result, certainly Surely make on or off between the first installation sense terminal 2521 and the second installation sense terminal 2522.

5C referring to Figure 1, for according to the circuit diagram of the detection pulse generating module of the utility model embodiment.Inspection Survey pulse generating module 2640 include capacitor 2642 (or first capacitor device), 2645 (or second capacitors) and 2646 (or Claim third capacitor), resistance 2643 (or first resistor device), 2647 (or second resistors) and 2648 (or third electricity Hinder device), buffer (buffer) 2644 (or first buffer) and 2651 (or second buffers), reverser 2650, two Pole pipe 2649 (or being first diode) and or door (OR gate) 2652 (or being first or door).It is using or is operating In, capacitor 2642 and resistance 2643 are series at a driving voltage (such as being known as VCC, and often ordered as a high levle) and ginseng It examines between current potential (herein using the current potential on ground as embodiment), tie point couples the input terminal of buffer 2644.Resistance 2647 It is coupled to the input terminal of a driving voltage (can be described as VCC) and reverser 2650.Resistance 2648 is coupled to the defeated of buffer 2651 Enter between end and a reference potential (herein using the current potential on ground as embodiment).The positive ending grounding of diode, negative terminal are also coupled to delay Rush the input terminal of device 2651.One end of capacitor 2645 and 2646 one end couple the output end of buffer 2644, capacitor jointly 2645 other end connects the input terminal of reverser 2650, and the other end of capacitor 2646 then couples the input of buffer 2651 End.The output end coupling of the output end and buffer 2651 of reverser 2650 or the input terminal of door 2652.It is noted that at this In this specification of case, current potential its " high levle " and " low level " be relative to another current potential in circuit or certain reference potential and (can be described as " high level " and " low level " sometimes) of speech, and again can be respectively as " logic high levle " and " logic low standard Position ".

When one end lamp cap of LED straight lamp is inserted into pair of lamp holder and other end lamp cap human body in electrical contact or LED straight lamp When end lamp cap is inserted into lamp holder, LED straight lamp is powered.At this point, installation detecting module enters detection-phase.Capacitor 2642 and resistance 2643 tie point level is high (being equal to driving voltage VCC) at the beginning, is gradually reduced at any time after, is finally down to zero.It is slow The input terminal coupling capacitance 2642 of device 2644 and the tie point of resistance 2643 are rushed, therefore exports high levle signal at the beginning, and When the tie point level of capacitor 2642 and resistance 2643 is down to low logic and judges level, low level signal is changed into.It is, slow It rushes device 2644 and generates an input pulse signal, persistently maintain low level (stopping exporting the input pulse signal) later.It is described The pulse width of input pulse signal is equal to (initial setting) time cycle, and the time cycle is by the appearance of capacitor 2642 Value and the resistance value of resistance 2643 determine.

Then illustrate that buffer 2644 generates the operation of the set time period of pulse signal.Due to capacitor 2645 and electricity One end of resistance 2647 is equal to driving voltage VCC, therefore the connecting pin of capacitor 2645 and resistance 2647 is also high levle.In addition, One end of resistance 2648 is grounded, and one end of capacitor 2646 receives the pulse signal of buffer 2644.So capacitor 2646 and resistance 2648 connecting pin in high levle at the beginning, then at any time gradually on be down to zero and (store and be equal or close to time capacitor The voltage of driving voltage VCC).Therefore, reverser 2650 exports low level signal, and buffer 2651 then exports high levle letter Number, and make or door 2652 in pulse signal output end 2541 export high levle signal (the first pulse signal).At this point, testing result Signal and pulse signal latch testing result to latch cicuit 2560 for the first time according to testing result.When capacitor 2646 and resistance 2648 The level of connecting pin when being down to low logic and judging level, buffer 2651 switchs to export low level signal, and makes or door 2652 Low level signal (stopping the first pulse signal of output) is exported in pulse signal output end 2541.Or the pulse that door 2652 is exported The pulsewidth of signal is determined by the capacitance of capacitor 2646 and the resistance value of resistance 2648.

Then the operation being illustrated in after the stopping output pulse signal of buffer 2644, that is, enter the operation of operational phase. Since capacitor 2646 stores the voltage close to driving voltage VCC, switched in the output of buffer 2644 by high levle low The level of the connecting pin of the moment of level, capacitor 2646 and resistance 2648 can be lower than zero, and fast to capacitor via diode 2649 Speed charges and the level of connecting pin is made to retract zero.Therefore, buffer 2651 still maintains output low level signal.

On the other hand, switch to the moment of low level by high levle in the output of buffer 2644, one end of capacitor 2645 Level reduces by zero by driving voltage VCC moment, makes the connecting pin low level of capacitor 2645 Yu resistance 2647.Reverser 2650 Output signal switchs to high levle, and make or door output high levle (the second pulse signal).At this point, testing result latch cicuit 2560 Signal and pulse signal latch testing result for the second time according to testing result.Then, resistance 2647 charges to capacitor 2645, makes The level of the connecting pin of capacitor 2645 and resistance 2647 be gradually increasing at any time and to equal than driving voltage VCC.When hold 2645 with When the level of the connecting pin of resistance 2647 rises supreme logic judgment level, reverser 2650 exports low level once again, and make or Door 2652 stops the second pulse signal of output.The pulsewidth of second pulse signal is by the capacitance of capacitor 2645 and the resistance value of resistance 2647 It is determined.

As described above, detection pulse generating module 2640 can generate the pulse signal-the of two high levles in detection-phase One pulse signal and the second pulse signal, are exported by pulse signal output end 2541, and the first pulse signal and the second pulse A setting time interval is spaced between signal, setting time interval is mainly by the resistance of the capacitance of capacitor 2642 and resistance 2643 Value determines.

And entering the operational phase after detection-phase, detection pulse generating module 2640 no longer generates pulse signal, and ties up Holding pulse signal output end 2541 is low level.

5D referring to Figure 1, for according to the circuit diagram of the detection decision circuit of the utility model embodiment.Detection is sentenced Determining circuit 2670 includes comparator 2671 (or first comparator) and resistance 2672 (or the 5th resistor).Comparator 2671 reverse side, which receives, refers to level signal Vref, and non-invert side is through the ground connection of resistance 2672 and while coupling switch coupling end 2581.Please referring also to Figure 15 A can be coupled by the signal that the first installation sense terminal 2521 flows into switching circuit 2580 via switch End 2581 exports and flows through resistance 2672.When the electric current for flowing through resistance 2672 it is excessive (that is, be greater than or equal to set-mounted electric current, Such as：Current value 2A) and the level on resistance 2672 is made (to can correspond to described two when being higher than the level with reference to level signal Vref Lamp cap is correctly inserted into the lamp holder), the testing result signal of the generation high levle of comparator 2671 is simultaneously defeated by testing result end 2571 Out.For example, comparator 2671 can export high levle in testing result end 2571 when LED straight lamp is correctly installed on lamp holder Testing result signal.When the electric current deficiency for flowing through resistance 2672 is higher than the level on resistance 2672 with reference to level signal (it can correspond to only one of which lamp cap when the level of Vref and be correctly inserted into the lamp holder), comparator 2671 generates low level Testing result signal is simultaneously exported by testing result end 2571.For example, when LED straight lamp is not correctly installed on lamp holder, Huo Zheyi End be installed on lamp holder and the other end through human body grounding when, electric current exports comparator 2671 in testing result end 2571 The testing result signal of low level.

5E referring to Figure 1, for according to the circuit diagram of the testing result latch cicuit of the utility model embodiment.Inspection Surveying result latch cicuit 2660 includes D flip-flop (D Flip-flop) 2661 (or first D flip-flop), resistance 2662 (or the 4th resistor) and or door 2663 (or second or door).Clock input (CLK) coupling of D flip-flop 2661 Testing result end 2571 is connect, input terminal D couples driving voltage VCC.When testing result end 2571 exports the testing result of low level When signal, D flip-flop 2661 exports low level signal in output end Q；When testing result end 2571 exports the detection of high levle When consequential signal, D flip-flop 2661 exports high levle signal in output end Q.Resistance 2662 is coupled to D flip-flop 2661 Output end Q and reference potential (such as the current potential on ground) between.When or 2663 return pulse signal output end 2541 of door output First pulse signal or the second pulse signal or D flip-flop 2661 are when the high levle signal that output end Q is exported, in detection As a result the testing result latch signal that end 2561 exports high levle is latched.Since detection pulse generating module 2640 is only in detection rank When section the first pulse signal of output or the second pulse signal, dominates or door 2663 exports high levle testing result latch signal, and Remaining time (including the operational phase after detection-phase) dominates testing result latch signal by D flip-flop 2661 as height Level or low level.Therefore, when testing result end 2571 did not occurred the testing result signal of high levle, D flip-flop 2661 maintain low level signal in output end Q, and testing result is made to latch the inspection that end 2561 also maintains low level in the operational phase Survey result latch signal.Conversely, when testing result end 2571 was when there is the testing result signal of high levle, the triggering of D type Device 2661 can latch and maintain high levle signal in output end Q.In this way, when testing result latch end 2561 enters the operational phase Maintain the testing result latch signal of high levle.

5F referring to Figure 1, for according to the circuit diagram of the switching circuit of the utility model embodiment.Switching circuit 2680 may include a transistor (transistor), such as bipolar junction transistors 2681 (or the first transistor) conduct One power transistor (power transistor).Power transistor can handle high current and power, be particularly used to switch electricity Lu Zhong.Collector coupling the first installation sense terminal 2521 of bipolar junction transistors 2681, base stage couple testing result and latch end 2561, and emitter-base bandgap grading switch coupling end 2581.When detection pulse generating module 2640 generates the first pulse signal or the second pulse letter Number when, of short duration conducting is made to detect decision circuit 2670 and be detected, to determine testing result by bipolar junction transistors 2681 Latch signal is high levle or low level.High levle is exported when testing result latch cicuit 2660 latches end 2561 in testing result Testing result latch signal when, conducting is made the first installation sense terminal 2521 and by bipolar junction transistors 2681 It is connected between two installation sense terminals 2522.Low standard is exported when testing result latch cicuit 2660 latches end 2561 in testing result When the testing result latch signal of position, cut-off is made the first installation sense terminal 2521 and the by bipolar junction transistors 2681 End between two installation sense terminals 2522.

Since external drive signal is AC signal, when being detected in order to avoid detection decision circuit 2670, external drive letter Number level just zero crossings cause detecting mistake.Therefore, detection pulse generating module 2640 generates the first pulse letter Number and the second pulse signal so that detection decision circuit 2670 detection twice, to avoid single detection when external drive signal standard Position is just the zero crossings the problem of.Preferably, the generation time difference of the first pulse signal and the second pulse signal is not institute And the 180 degree phase difference of external drive signal described in non-corresponding the integer multiple of the period half of external drive signal is stated, i.e., Integer multiple.In this way, when one of the first pulse signal and the second pulse signal generate, if unfortunate external drive signal is zero Nearby, avoidable external drive signal is also in zero crossings when another generation for point.

The generation time of above-mentioned first pulse signal and the second pulse signal is poor, i.e., setting time interval can be with formula table Show as follows：

Setting time interval=(X+Y) (T/2)

Wherein, T is the period of external drive signal, and X is integer more than or equal to zero, 0<Y<1.

The preferable range of Y is between 0.05-0.95, between more preferably 0.15-0.85.

Furthermore when entering detection-phase in order to avoid installation detecting module, the level of driving voltage VCC is too low to will cause peace The circuit logic misjudgment of dress detecting module is begun to ramp up.It may be set in driving voltage in the generation of the first pulse signal VCC is reached or higher than predetermined level when generates, and decision circuit 2670 is detected after so that driving voltage VCC is reached enough levels It carries out, to avoid the circuit logic misjudgment of level installation detecting module caused by insufficient.

According to the above description, when LED straight lamp one end lamp cap insertion lamp holder and other end lamp cap be suspension joint or electricity Property contact human body when, make the testing result signal for detecting decision circuit output low level because impedance is big.Testing result latches electricity The detection of low level is latched into the testing result signal of low level according to the pulse signal of detection pulse generating module in road As a result latch signal, and testing result is also maintained when the operational phase.In this way, switching circuit can be made to maintain cut-off and avoid continuing It is powered.It is possible so also to can avoid human electric shock, so as to meet the requirements.And when the both ends lamp cap of LED straight lamp is correct When being inserted into lamp holder, make the testing result letter for detecting decision circuit output high levle because the impedance of LED straight lamp circuit itself is small Number.Testing result latch cicuit locks the testing result signal of high levle according to the pulse signal of detection pulse generating module It is saved as the testing result latch signal of high levle, and also maintains testing result when the operational phase.In this way, switching circuit can be made to tie up It holds conducting and is persistently powered, make the normal operating when operational phase of LED straight lamp.

In other words, in some embodiments, the lamp cap described in one end of the LED straight lamp is inserted into the lamp holder and another When lamp cap described in one end is suspension joint or human body in electrical contact, the testing result letter of the detection decision circuit input low level Number the testing result latch cicuit is arrived, then one low level signal of detection pulse generating module output is tied to the detection Fruit latch cicuit makes a testing result latch signal of the testing result latch cicuit output low level so that the switch is electric Road cut-off, wherein the cut-off of the switching circuit makes to end between the first installation sense terminal and the second installation sense terminal, Even if also the LED straight lamp enters a not on-state.

And in some embodiments, when two lamp cap of the LED straight lamp is correctly inserted into the lamp holder, the inspection The testing result signal of decision circuit input high levle is surveyed to the testing result latch cicuit, locks the testing result A testing result latch signal of circuit output high levle is deposited so that the switching circuit is connected, wherein the switching circuit is led It is logical to make to be connected between the first installation sense terminal and the second installation sense terminal, even if also the LED straight lamp operates in one On state.

It is worth noting that, the pulsewidth for the pulse signal that detection pulse generating module generates in 10us between 1ms, make With only LED straight lamp be powered moment when, make switching circuit that the of short duration time be connected using this pulse signal.It can produce in this way A raw pulse current flows through detection decision circuit and carries out detection judgement.Because generation be the pulse of short time due to for a long time lead Lead to non-, Danger Electric shock risk can't be caused.Furthermore testing result latch cicuit also maintains testing result when the operational phase, no longer Change the testing result previously latched because circuit state changes, and avoids the problem that testing result variation and cause.And it installs Detecting module (i.e. switching circuit, detection pulse generating module, testing result latch cicuit and detection decision circuit) can collect It at into chip, can be embedded into circuit in this way, the circuit cost and volume of installation detecting module can be saved.

Though applicant in previous case, such as:In CN106015996A, proposes and utilize detection pulse generating module The first pulse signal and the second pulse signal are generated so that detection decision circuit carries out detection judgement, applicant is when implementing to this The embodiment of scheme has carried out further improvement, it is intended to reduce the volume of detecting module and further increase detection judgement Precision.Next the detailed improved embodiment of description.

Then, referring again to Figure 15 G, when LED straight lamp changes the outfit when lamp holder, detecting pulse generating module 2740 exists (this time determines the pulse period) for a period of time, output rises to one first high levle electricity from one first low level voltage Pressure, and this first high levle voltage is exported to testing result latch cicuit 2760 via a path 2741.Testing result latches electricity After road 2760 receives this first high levle voltage, one second high levle voltage is exported simultaneously to switching circuit via a path 2761 2780 with detecting pulse generating module 2740.After switching circuit 2780 receives this second high levle voltage, switching circuit 2780 Conducting is so that an electric power loop of LED straight lamp (includes at least the first installation sense terminal 2521, switching circuit 2780, path 2781, decision circuit 2770 and the second installation sense terminal 2522 are detected) conducting；And at the same time, detect pulse generating module 2740 a period of time after receiving the second high levle voltage returned by testing result latch cicuit 2760, (this time determined Determine pulse width), export from the first high levle voltage drop back to the first low level voltage (the first low level voltage of first time, First high levle voltage and secondary first low level voltage constitute one first pulse signal).And detect decision circuit 2770 LED straight lamp electric power loop conducting when, detect on its circuit one first sampled signal (such as：Voltage signal), when this First sampled signal be greater than and/or be equal to a setting signal (such as：One reference voltage) when, it is former according to the application of above-mentioned this programme Reason indicates that LED straight lamp is correctly installed in lamp holder, therefore detects decision circuit 2770 via a path 2771 output one the Three high levle voltages (the first high levle signal) are to testing result latch cicuit 2760.Testing result latch cicuit 2760 receives this Third high levle voltage exports in turn and maintains one second high levle voltage (the second high levle signal) to switching circuit 2780, opens Powered-down road 2780 receives this second high levle voltage and then maintains to be connected the electric power loop maintenance conducting so that LED straight lamp, Between detecting pulse generating module 2740 no longer generates pulse export.

When this first sampled signal is less than this setting signal, according to the application principle of above-mentioned the utility model, LED is indicated Straight lamp is not yet correctly installed in lamp holder, therefore is detected decision circuit 2770 and exported a third low level voltage (first low standard Position signal) to testing result latch cicuit 2760.It is defeated in turn that testing result latch cicuit 2760 receives this third low level voltage Out and maintain the second low level voltage (the second low level signal) to switching circuit 2780, it is second low that switching circuit 2780 receives this Level voltage and then maintenance end so that the electric power loop of LED straight lamp maintains open circuit.In the case, user is avoided to exist LED straight lamp is not yet correctly installed on the problem of lamp holder Nei Shiyin accidentally touches LED straight lamp current-carrying part and gets an electric shock.

After the electric power loop of above-mentioned LED straight lamp maintains open circuit a period of time (i.e. pulse cycle time), pulse is detected The output that module 2740 occurs rises to the first high levle voltage from the first low level voltage again, and defeated via path 2741 Out to testing result latch cicuit 2760.After testing result latch cicuit 2760 receives this first high levle voltage, via path 2761 export one second high levle voltage to switching circuit 2780 and detecting pulse generating module 2740 simultaneously.Work as switching circuit After 2780 receive this second high levle voltage, switching circuit 2780 is connected again so that the electric power loop of LED straight lamp (at least wraps Include the first installation sense terminal 2521, switching circuit 2780, path 2781, detection decision circuit 2770 and the second installation sense terminal 2522) it is also connected again；At the same time, detecting pulse generating module 2740 is returned in reception by testing result latch cicuit 2760 It a period of time (this time determines pulse width) after the second high levle voltage passed, exports from the first high levle voltage drop Return one first low level voltage (the first low level voltage of third time, secondary first high levle voltage and the 4th time the One low level voltage constitutes one second pulse signal).And detect decision circuit 2770 LED straight lamp electric power loop again When conducting, also detect again on its circuit one second sampled signal (such as：Voltage signal), when this second sampled signal is greater than And/or be equal to setting signal (such as：One reference voltage) when, according to the application principle of above-mentioned the utility model, indicate LED straight tube Lamp is correctly installed in lamp holder, therefore is detected decision circuit 2770 and exported a third high levle voltage (first via path 2771 High levle signal) to testing result latch cicuit 2760.Testing result latch cicuit 2760 receive this third high levle voltage into And export and maintain one second high levle voltage (the second high levle signal) to switching circuit 2780, switching circuit 2780 receives this The electric power loop maintenance conducting so that LED straight lamp is connected in second high levle voltage and then maintenance, detects pulse generation mould therebetween Block 2740 no longer generates pulse wave output.

When this second sampled signal is less than this setting signal, according to the application principle of above-mentioned the utility model, LED is indicated Straight lamp is not installed in lamp holder correctly yet, therefore is detected decision circuit 2770 and exported a third low level voltage (first low standard Position signal) to testing result latch cicuit 2760.It is defeated in turn that testing result latch cicuit 2760 receives this third low level voltage Out and maintain one second low level voltage (the second low level signal) to switching circuit 2780, switching circuit 2780 receive this second Low level voltage and then maintenance end so that the electric power loop of LED straight lamp maintains open circuit.

Then, please referring also to Figure 15 H to Figure 15 K, when LED straight lamp changes the outfit when lamp holder, a driving voltage is via electricity 2742 pairs of capacitors 2743 are hindered to charge, and when the voltage of capacitor 2743 rise to be enough to trigger schmitt trigger 2744 when, Schmitt trigger 2744 from initial one first low level voltage become one first high levle voltage output to or door 2763 One input terminal.Or door 2763 is receiving after the first high levle voltage that schmitt trigger 2744 is exported or door 2763 Export one second high levle voltage to transistor 2782 base terminal and resistance 2747.When the base terminal of transistor 2782 receives From or the second high levle voltage that is exported of door 2763 after, the collector terminal of transistor 2782 is connected with emitter-base bandgap grading end so that The electric power loop of LED straight lamp (includes at least the first installation sense terminal 2521, transistor 2782, resistance 2774 and the second installation Sense terminal 2522) conducting；And at the same time, what the base terminal of transistor 2746 was exported via the reception of resistance 2747 or door 2763 After second high levle voltage, ground connection is connected with emitter-base bandgap grading end in the collector terminal of transistor 2746, so that the voltage of capacitor 2743 is via electricity Resistance 2745 is discharged over the ground, when the undertension of capacitor 2743 is to trigger schmitt trigger 2744, schmitt trigger 2744 Output drop back to the first low level voltage (the first low level voltage of first time, the first high levle electricity from the first high levle voltage Pressure constitutes one first pulse signal with secondary first low level voltage).And when the conducting of the electric power loop of LED straight lamp, By transient response flow through in LED power circuit capacitor (such as：The filter capacitor of filter circuit) electric current flow through transistor 2782 with resistance 2774, and a voltage signal is formed on resistance 2774, this voltage signal is via comparator 2772 and a reference Voltage (being 1.3V in the present embodiment, so without being limited thereto) is compared, when this voltage signal is greater than and/or is equal to this reference voltage When, comparator 2772 exports a third high levle voltage to the frequency input CLK of D flip-flop 2762, simultaneously because D type touches The data input pin D connection driving voltage of device 2762 is sent out, therefore the output end Q of D flip-flop 2762 exports a high levle voltage Arrive or another input terminal of door 2763 so that or door 2763 export and maintain the second high levle voltage to the base stage of transistor 2782 End, so that the electric power loop of transistor 2782 and LED straight lamp maintains conducting.Due to or door 2763 export and maintain the Two high levle voltages, therefore transistor 2746 also maintains conducting to be grounded, so that the voltage of capacitor 2743 can not rise to foot To trigger schmitt trigger 2744.

And when the voltage signal on resistance 2774 is less than reference voltage, comparator 2772 exports a third low level voltage To the frequency input CLK of D flip-flop 2762, simultaneously because the initial output value of D flip-flop 2762 is zero, therefore D type The output end Q of trigger 2762 exports a low level voltage and arrives or another input terminal of door 2763, and due to or door 2763 The schmitt trigger 2744 that one end is connected also restores to export the first low level voltage, therefore or door 2763 export and maintain the Two low level voltages to transistor 2782 base terminal so that transistor 2782 maintain cut-off and LED straight lamp electricity Resource loop maintains open circuit.However, due to or door 2763 export and maintain the second low level voltage, transistor 2746 also maintains In off state, voltage to be driven again charges to capacitor 2743 via resistance 2742 to repeat (pulse) next time Detecting.

It is worth noting that, the pulse period is determined by the resistance value of resistance 2742 and the capacitance of capacitor 2743, In some embodiments, the time interval of pulse signal is 3ms~500ms, and further, the time interval of pulse signal is 20ms ~50ms；Pulse width is determined by the resistance value of resistance 2745 and the capacitance of capacitor 2743, in certain embodiments, arteries and veins The width for rushing signal includes 1us~100us, and further, the width of pulse signal includes 10us~20us；Zener diode 2748 provide protection against, but it can be omitted；Resistance 2774 is considered based on power factor (PF), can be two resistor coupled in parallel, equivalent Resistance value includes 0.1 ohm~5 ohm；Resistance 2776 and 2777, which provides partial pressure, ensures that input voltage is higher than the ginseng of comparator 2773 Examine voltage (being 0.3V in the present embodiment, so without being limited thereto)；Capacitor 2778 provides pressure stabilizing and filter function；Diode 2775 ensures The one-way of signal transmission.In addition, at this point it is to be emphasized that, installation detecting module disclosed by the utility model is applicable to it His both-end into electricity LED illumination device, such as：LED light with Double-End Source construction for electricity and comprising directly utilizing alternating current Or the signal exported using ballast, as LED light of external drive voltage etc., the utility model is not intended to limit installation detecting The application range of module.

It is intended to first illustrate herein, installation that the installation detecting module of the present embodiment is utilized detecting principle is and aforementioned the Two preferred embodiments are identical, are all based on the principle that capacitance voltage will not mutate, the capacitor in LED straight lamp electric power loop Before electric power loop conducting, both end voltage is zero and short-circuit condition is presented in transient response；And when electric power loop is in LED straight tube When lamp is correctly installed on lamp holder, transient response current-limiting resistance is smaller and peak value of response electric current is larger, when electric power loop is straight in LED When spot is not installed on lamp holder correctly, the principles such as transient response current-limiting resistance is larger and peak value of response electric current is smaller are subject to reality It applies, and the leakage current of LED straight lamp is made to be less than 5MIU.In other words, exactly sentence through the mode of detecting peak value of response electric current Whether disconnected LED straight lamp is correctly installed in lamp holder.Therefore about the transient current portion in the case where working normally and changing lamp test Divide the explanation that can refer to previous embodiment, it is no longer repeated in this.It is beneath to transport the integrated circuit for only just installing detecting module It is illustrated.

Referring again to Figure 15 L, when LED straight lamp changes the outfit when lamp holder, LED straight lamp is in the case where there is one end into electricity Meeting is so that driving voltage VCC is provided to the modules/circuits in installation detecting module 2520.2840 meeting of pulse generation auxiliary circuit It reacts on driving voltage VCC and carries out charging action.(this time determines the pulse period) over time, output voltage (claiming the first output voltage in this) from one first low level voltage is increased over one, and forward (voltage value can be according to electricity for threshold voltage Design and define in road), and via the input terminal IN1 of a path 2841 output to integrated control module 2860.Integrated control module 2860 after input terminal IN1 the first output voltage of reception, the control signal (for example, one of an enable is exported via a path 2861 High levle voltage) to switching circuit 2880 and pulse generation auxiliary circuit 2840.When switching circuit 2880 receives the control of this enable After signal processed, switching circuit 2880 is connected so that an electric power loop of LED straight lamp (includes at least the first installation sense terminal 2521, switching circuit 2880, path 2881, detection determine auxiliary circuit 2870 and the second installation sense terminal 2522) conducting；And At the same time, pulse generation auxiliary circuit 2840 can react on the control signal of enable and discharge path is connected to carry out electric discharge and move Make, and a period of time after the control signal for receiving the enable returned by integrated control module 2860, (this time determined Determine pulse width), the first output voltage gradually drops back to the first low level voltage from the voltage quasi position for being more than forward threshold voltage.Its In, when the first output voltage is decreased below reverse threshold voltage (voltage value can be defined according to circuit design), integrate Control module 2860 can react on the first output voltage and the control signal of enable is pulled down to forbidden energy level (that is, output forbidden energy Control signal, wherein the control signal of forbidden energy is, for example, a low level voltage) so that control signal have impulse form Signal waveform (that is, by the low level voltage of the first time in control signal, high levle voltage and secondary low level voltage Constitute one first pulse signal).And it detects and determines that auxiliary circuit 2870 in the electric power loop conducting of LED straight lamp, detects it On circuit one first sampled signal (such as：Voltage signal), and the first sampled signal is supplied to collection via input terminal IN2 At control module 2960.When integrated control module 2960 determine this first sampled signal be greater than or equal to a setting signal (such as： One reference voltage) when, according to the application principle of above-mentioned the utility model, indicate that LED straight lamp is correctly installed in lamp holder, therefore Integrated control module 2860 can export and maintain the control signal of enable to switching circuit 2880, and switching circuit 2880 receives with greetings The control signal of energy maintains to be connected in turn the electric power loop maintenance conducting so that LED straight lamp, therebetween integrated control module 2860 No longer generate pulse output.

On the contrary, when integral control circuit 2860 determines that this first sampled signal is less than this setting signal, according to above-mentioned The application principle of the utility model indicates that LED straight lamp is not yet correctly installed in lamp holder, therefore integral control circuit can export And maintaining the control signal of forbidden energy to switching circuit 2880, switching circuit 2880 receives the control signal of this forbidden energy and then maintains to cut Only so that the electric power loop of LED straight lamp maintains open circuit.

Discharge path due to pulse generation auxiliary circuit 2840 is ended, so that 2840 weight of pulse generation auxiliary circuit It is new to carry out charging action.Therefore, after the electric power loop of above-mentioned LED straight lamp maintains open circuit a period of time (i.e. when the pulse period Between), the first output voltage of pulse generation auxiliary circuit 2840 is increased over forward threshold value from the first low level voltage again Voltage, and via the input terminal IN1 of the output of path 2841 to integrated control module 2860.Integrated control module 2860 is from input After holding IN1 to receive the first output voltage, control signal can be pulled to enable level (that is, output enable from forbidden energy level again Control signal), and the control signal of enable is provided to switching circuit 2880 and pulse generation auxiliary circuit 2840.When Switching circuit 2880 receive this enable control signal after, switching circuit 2880 be connected so that the electric power loop of LED straight lamp (extremely It less include the first installation sense terminal 2521, switching circuit 2880, path 2881, detection judgement auxiliary circuit 2870 and the second installation Sense terminal 2522) be also connected again.At the same time, pulse generation auxiliary circuit 2840 can react on the control signal of enable again And discharge path is connected and carries out discharging action, and in the control for receiving the enable returned by integrated control module 2860 A period of time (this time determines pulse width) after signal, the first output voltage is quasi- from the voltage more than forward threshold voltage Position gradually drops back to the first low level voltage again.Wherein, it when the first output voltage is decreased below reverse threshold voltage, integrates Control module 2860 can react on the first output voltage and the control signal of enable is pulled down to forbidden energy level, so that control Signal has the signal waveform of impulse form (that is, by the low level voltage of the third time in control signal, secondary high levle Voltage and the 4th low level voltage constitute one second pulse signal).And it detects and determines auxiliary circuit 2870 in LED straight lamp Electric power loop when being connected again, also detect again on its circuit one second sampled signal (such as：Voltage signal), and will Second sampled signal is supplied to integrated control module 2960 via input terminal IN2.When this second sampled signal is greater than and/or is equal to Setting signal (such as：One reference voltage) when, according to the application principle of above-mentioned the utility model, indicate that LED straight lamp is correctly pacified Loaded in lamp holder, therefore integrated control module 2860 can export and maintain the control signal of enable to switching circuit 2880, switch Circuit 2880 receives the control signal of this enable and then maintains to be connected so that the electric power loop of LED straight lamp maintains conducting, therebetween Integrated control module 2860 no longer generates pulse wave output.

It is practical new according to above-mentioned when integral control circuit 2860 determines that this second sampled signal is less than this setting signal The application principle of type indicates that LED straight lamp is not installed in lamp holder correctly yet, therefore integral control circuit can export and maintain to prohibit Can control signal to switching circuit 2880, switching circuit 2880 receive the control signal of this forbidden energy so that maintain to end so that The electric power loop of LED straight lamp maintains open circuit.In the case, user is avoided not yet correctly to be installed on lamp in LED straight lamp The problem of seat Nei Shiyin accidentally touches LED straight lamp current-carrying part and gets an electric shock.

Internal circuit/module running of the beneath installation detecting module for being more particularly described the present embodiment.Please referring also to scheme 15M to Figure 15 P, when LED straight lamp changes the outfit when lamp holder, a driving voltage VCC fills capacitor 2743 via resistance 2742 Electricity, and it is enough (that is, be more than forward threshold voltage) when trigger pulse generates unit 2862 when the voltage of capacitor 2843 rises to, arteries and veins The output that punching generates unit 2862 can become one first high levle voltage output to detection from one first initial low level voltage As a result latch units 2863.Testing result latch units 2863 are receiving first exported from impulse generating unit 2862 After high levle voltage, testing result latch units 2863 can export one second high levle voltage to transistor via output end OT 2882 base terminal and resistance 2846.When the base terminal reception of transistor 2882 is defeated from 2863 institute of testing result latch units After the second high levle voltage out, the collector terminal of transistor 2882 is connected with emitter-base bandgap grading end, so that the power supply of LED straight lamp returns Road (including at least the first installation sense terminal 2521, transistor 2882, resistance 2872 and the second installation sense terminal 2522) conducting.

And at the same time, the base terminal of transistor 2845 receives the second high levle electricity on output end OT via resistance 2846 After pressure, ground connection is connected with emitter-base bandgap grading end in the collector terminal of transistor 2845, so that the voltage of capacitor 2843 is put over the ground via resistance 2844 Electricity, when the undertension of capacitor 2843 generates unit 2862 with trigger pulse, the output of impulse generating unit 2862 is from first High levle voltage drop back to the first low level voltage (the first low level voltage of first time, the first high levle voltage with it is secondary First low level voltage constitutes one first pulse signal).And when the conducting of the electric power loop of LED straight lamp, pass through transient response Flow through in LED power circuit capacitor (such as：The filter capacitor of filter circuit) electric current flow through transistor 2882 and resistance 2872, and a voltage signal is formed on resistance 2872, this voltage signal is provided to input terminal IN2, so that detection unit 2864 can be compared this voltage signal with a reference voltage.

When detection unit 2864 determines that this voltage signal is greater than or equal to this reference voltage, detection unit 2864 is exported One third high levle voltage is to testing result latch units 2863.And when detection unit 2864 determines the voltage letter on resistance 2872 When number being less than reference voltage, detection unit 2864 exports a third low level voltage to testing result latch units 2863.

Wherein, testing result latch units 2863 can latch third high levle voltage/the provided by detection unit 2864 Three low level voltages, then by the progress of signal provided by the signal of latch and impulse generating unit 2862 or logical operation, and According to or logical operation result determine output control signal be the second high levle voltage or the second low level voltage.
