Embodiment
Below in conjunction with accompanying drawing the present invention is done further carefully to state.
Fig. 1 is first kind of structural principle circuit diagram of a LC fluorescent lamp ballast of the preferred embodiment of the present invention, the output (K) of its homomorphism relay (SSR) also is connected in capacitor (C1) two ends, diode (DQ) is the sampling element of described sample circuit, this diode (DQ) series connection is in starter (S) loop of fluorescent lamp tube (EL), be connected on the output of bridge rectifier (DZ) after the same filtering capacitor of trigger end (C2) parallel connection of solid-state relay (SSR), the input of bridge rectifier (DZ) is connected on the two ends of sampling diode (DQ), (DZ), (C2), (SSR) drive circuit of formation switch state.The circuit of Fig. 1 is like this work: when power connection, the power voltage insufficient that is added to LC (C1, B) ballast circuit is so that fluorescent lamp starting, and all voltages are added in two of starter and extremely go up.The starting voltage of glow starter is about 140V, produces glow discharge under supply voltage immediately, and glow discharge is connected bimetal leaf, and filament is preheated.Preheat curent is gone up at sampling diode (DQ) and is produced pressure drop, this voltage is added to the trigger end of solid-state relay (SSR) by bridge rectifier (DZ), filtering capacitor (C2), make solid-state relay (SSR) conducting, at this moment, circuit changes inductance (B) ballast circuit into by the LC fluorescent-lamp ballast circuit, makes lamp pipeline start up by preheating in the Inductive ballast circuit.When lamp is lighted, start and finish, glow starter open circuit (modulating voltage is lower than the starting voltage of glow starter), sampling diode (DQ) sampled signal disappears, the trigger end dead electricity of solid-state relay (SSR), solid-state relay (SSR) turn-offs, and circuit changes the LC ballast circuit into by inductance (B) ballast circuit.The sampling diode (DQ) of this circuit is two groups, and 6 every group, the pressure drop of generation is about 4～5 volts.
