Embodiment
Details are as follows in conjunction with the accompanying drawings for a preferred embodiment of the present utility model:
Referring to Fig. 1; this split socket joint type electronic inductance ballast includes an Inductive ballast 1; an electronic power converter that can connect T5 fluorescent tube 4 one ends 3, the stop voltage protector 5 that can connect T5 fluorescent tube 4 other ends are arranged, and two splicing ears of described electronic power converter 3 are connected two splicing ears of described stop voltage protector 5 respectively with an overcurrent protective device 8 by described Inductive ballast 1.
Referring to Fig. 2, Fig. 3 and Fig. 4; above-mentioned electronic power converter 3 is the socket cap with stop voltage protector 5 and can overlaps to wear and be connected T5 fluorescent tube 4: there are two of two jacks and the T5 fluorescent tube one end pin couplings of pegging graft its socket cap the inner, and socket cap outer end have two peg graft pin can with base 2,6 couplings that are fixed on the Fluorescent Light and Fixtures 9.Have the heat radiation slotted eye on the shell of above-mentioned electronic power converter 3.Above-mentioned overcurrent protective device 8 is the small column body, its termination have two peg graft pin can with the starter base inserting.
The circuit structure of above-mentioned electronic power converter 3, overcurrent protective device 8 and stop voltage protector 5 is respectively as Fig. 6, Fig. 7 and shown in Figure 8.
Operation principle:
1. the electronic power converter 3
When the electronic power converter of Fig. 6 powers on, the start-up circuit of forming by resistance R 1, capacitor C 3 and bidirectional trigger diode DIAC, when institute's charging voltage reaches the puncture voltage of bidirectional trigger diode DIAC on the capacitor C 3, for half-bridge lower end transistor T 2 base stages provide a positive triggering pulse, make T2 begin conducting.The positive feedback of saturable transformer causes the enough big voltage of L2 winding output to make T2 base stage positively biased, jumps to saturation conduction fast.Institute's charging voltage constitutes loop discharge, start-up circuit end-of-job by diode D5 and T2 on the capacitor C 3.
T2 jumps to saturation conduction fast, and the collector current of T2 makes and produces in capacitor C 4, C5 inductance L 3, the L4 branch road because of electric current rises to excitation, and forming frequency is the series resonance of fo, and resonance is lighted fluorescent tube at the high pressure of C4 and the generation of L4 junction.Because ω L3＜＜ω L4,1/ (ω C5)＜＜1/ (ω C4), frequency of oscillation fo is mainly by L4 and C4 decision.
It is to rise because of generation electric current in capacitor C 4, C5 inductance L 3, the L4 branch road increases in time that the electronic power converter enters steady state condition, so that the saturable transformer magnetic core is gradually saturated, flux value changes gradually and reduces, the induced potential decline that the L2 winding produces.T2 base drive descends thereupon, and the collector current that flows through the L3 winding also descends.Descend, can produce the induced potential of reversed polarity at L1, L2, three windings of L3 because of the inductance prevention collector current of winding.Voltage positive feedback rises to the reversed polarity induced potential, and the L2 winding produces enough big reversed polarity induced potential becomes instead partially the T2 base stage, withdraws from saturated jumping to and ends; The L1 winding produces enough big reversed polarity induced potential makes the T1 base stage become positively biased, withdraws from by jumping to saturated.So go round and begin again, T2 and T1 take turns saturated and end, and form the vibration operating mode.The frequency of oscillation of steady state condition is by comprehensive decision such as saturable transformer magnetic core size, saturation flux density, umber of turn, transistor storage time.
Resistance R 2 provides initial DC channel for the collector current of T2, easily produces gain so that the T2 working point enters the linear amplification district, lights fluorescent tube thereby make the easy starting of oscillation of inverter enter operating mode.The R2 resistance should rationally be chosen, and its resistance is too big, and the inverter difficult oscillation starting can not be worked; Its resistance too low power consumption is big, and the electronic power transducer effciency descends.
Fluorescent tube one end filament pre-heating is the effect of the industrial frequency AC input starting current of bridge rectifier.Fluorescent tube other end filament pre-heating voltage is that above-mentioned series resonance electric current dividing potential drop on inductance L 4 produces.By the selected parameter of design, guarantee that the voltage magnitude preheating of dividing potential drop generation appropriately and not can be burnt filament.
2. the stop voltage protector 5
3. overcurrent protector 8
For than the high-power fluorescent lamp electric ballast; when fluorescent tube has been broken or do not have fluorescent tube; resonant circuit does not have damping; and that circuit will produce will be very high-power; have bigger source current this moment; overheated for preventing that overcurrent from producing, even damage components and parts, it is very necessary taking the overcurrent protection measure.
The characteristic curve of overcurrent protector is seen Fig. 2, and electrical schematic diagram is seen Fig. 7.Its operation principle is:
Diode D1～D4 constitutes rectifier bridge, and the AC rectification of importing is become direct current.Polarity as shown in Figure 7.During operate as normal, positive voltage is given triggering signal of bidirectional thyristor TRIAC, the bidirectional thyristor TRIAC conducting of main channel through resistance R 2.The ballast electric current constitutes the loop through rectifier bridge to TRIAC, R1.Because the R1 resistance is very little, makes the pressure drop on the R1 very low, causes U
C1Lower, so diode D5 and triode T end.Because voltage-stabiliser tube VS does not puncture, so this branch road is obstructed, LED does not work among this moment another subaisle branch road R5-LED-VS.When overcurrent, the pressure drop of big electric current on R1 raises, and makes U
C1Voltage and then raise, cause diode D5 and triode T conducting.The collector voltage of triode T reduces, and the bidirectional thyristor TRIAC of main channel is ended, and this moment, LED was bright, sends over-current signal because voltage-stabiliser tube VS punctures, and the ballast electric current circulates in above-mentioned another subaisle branch road R5-LED-VS.Because the bidirectional thyristor TRIAC of main channel ends, and subaisle light-emitting diode current in loop is placed restrictions in very little value by resistance R 5, so played overcurrent protection.
