[Prior Art] Refer to Figure 1 for the resonant circuit molding structure of the fluorescent lamp lighting circuit, which can be seen from the figure. The resonant circuit module has various forms in the figure, and the main feature is that the tt vibration capacitor (Ct) is connected in series with the lamp filament, thereby forming a series spectrum circuit module. With the circuit module of such a form, the filament of the lamp must carry a large preheating resonant current, which is easy to cause the lamp filament to burn out. ❹βPlease refer to _ 3' as the circuit diagram of the fluorescent lamp electronic ballast. It can be seen from the figure that the middle of the diode (10) is powered by a resistor or a control unit (for example: (6) to supply the driving waste current to start the vibration signal, and its protection The circuit method uses the filament as the no-load protection. When the filament is dissolved or no load, the circuit will not be able to stop working. If the lamp is abnormal (generating a large current), the filament cannot be instantly cut, it will burn the whole The main reason for the lack of service life of electronic ballast related products on the market is 201026147. It is: ι·filament aging causes light decay and increases power consumption; 2. Filament aging easily damages electronic ballast, damaged electronic ballast Completely damage the lamp, and finally burn the circuit board; 3. The product on the market needs to preheat the filament to start (the quick start product also increases the starting current)' and the preheating of the large current is the most likely to cause filament damage and shorten the life of the lamp; It is the blackhead of the lamp, the light decay (insufficient amount of light), the flashing of the lamp, the melting of the filament, etc. ❹ Another 'US invention patent 7,180, 251 "ELECTRONIC POWER CIRCUIT FOR GAS DISCHARGE LAMPS" (hereinafter referred to as the citation), in the previous technique shown in the cited case Fig.l (as shown in Figure 6), the transistor 6 (:, 6 (1 rear) The inductor 8, the capacitor 9, the capacitor 11, and the lamp tube 10 form a (four) vibrating circuit, and the circuit is directly connected to the DC negative terminal, thereby generating a high-voltage DC pulse to start the cold cathode tube, which belongs to the parallel spectrum series load, although the reference case and the present Although the technical field of the invention is slightly related, it is different from the present invention in the field of practical application or in terms of efficacy.

Low, no need for impurities, slowing filament loss, no use of electrolytic grid elements can greatly slow down the aging of the circuit, even if it is frequently switched, it will not harm the circuit components and the lamp. ^ ° Another object of the present invention is to provide an extension Lamp life and drive method with power factor correction and no load protection, in addition to effectively protecting the circuit mechanism and 201026147 Extends the life of the circuit. It can take into account the advantages of the circuit, the low cost, and the high compatibility of the circuit products.

The parallel ship circuit can be designed in the following form: ❹ 1. Figure 2-1 As shown, it is connected to a lamp (Lamp) filament series impedance matching capacitor (Cz)' and a spectral resonant capacitor (Ct) to form a parallel resonant circuit module; one end of the parallel spectral circuit module is connected to a resonant current limiting inductor ( Inductor), the other end of the read current limiting inductor (1 nductor) is connected to an alternating current source (Source) of the i-knife switching circuit or the power output of the vibrating circuit: the other end of the parallel resonant circuit module is connected to a Used to isolate the DC cross-connect capacitor (Cf), the other end of the parent connection valley is the output (Drain), which can output the AC source or DC positive and negative terminals of the charge and discharge current path. 201026147 2. As shown in Figure 2-2 , is connected to the lamp filament (Lamp) series impedance matching capacitor (Cz), and with the resonance (Ct) constitutes a parallel resonant circuit module; one end of the parallel resonant circuit module is connected to a spectral limiting current limiting inductor (Induct〇r) and a cross-connecting capacitor (Cf) for isolating direct current 'the cross-connecting capacitor (Cf) The other end is connected to the AC source of the switching switch circuit or the power output of the vibrating circuit; the other end of the parallel resonant circuit module is the output terminal (Drain), which can output the AC source or DC positive and negative of the charging and discharging current path. 3. As shown in Figure 2-3, the lamp is connected to the lamp impedance matching capacitor (Cz) in series and constitutes a parallel resonant circuit module with the resonant capacitor (ct); one end of the parallel resonant circuit module is Connecting a resonant current limiting inductor (Induct〇r), the other end of the resonant current limiting inductor (I nduct〇r) is connected to an AC source (source) outputted by the switching circuit or the power of the oscillation circuit; the parallel resonant circuit mode The other end of the group is the output (Drain), which can output the AC source of the charging and discharging current path. 4. As shown in Figure 2-4, the difference from Figure 2_3 above is the lamp (1^〇1) filament. The position of the series impedance matching capacitor (Cz) is different, and its circuit performance is 2. As shown in Figure 2-5, the difference between Figure 2 and Figure 3 is that the lamp is matched with the impedance matching capacitor (Czl) and the impedance matching capacitor (Cz2) at both ends of the lamp. No. 2. As shown in Figure 2-6, 'Lamp filament series impedance matching capacitor (czi) and impedance matching capacitor (Cz2)' and parallel resonant circuit module with resonant capacitor (ct) The other end of the parallel resonant circuit module is connected to a resonant current limiting inductor (Inductor) The other end of the parallel resonant circuit module is connected to a cross-connected electric valley (Cf) for isolating direct current, and the other end of the parent connected electric valley is an output end (j) rain), which can output a charging and discharging current path.

When there is no load, the impedance matching capacitor (CZ) will stop charging and discharging. At this time, the driving voltage and current of the diode (D5) will be stopped to start the oscillation signal, and the circuit will stop working to achieve the protection function. When the load impedance is too large (the lamp is abnormal), a large current is generated, the circuit will become larger due to the load impedance, and the impedance matching capacitor (Cz) stops charging and discharging, and is automatically regarded as a no-load state, and the circuit stops working to achieve the protection function. Due to the oscillating operation of the driving voltage and current signals of the driving diode (D5) or the driving end of the switching element, the impedance matching capacitor (Cz) is charged and discharged synchronously, so that the circuit operating efficiency is greatly improved, and the power factor can be approached. 1.
