Embodiment
Do carefully to state further to the present invention below in conjunction with accompanying drawing and preferred embodiment.
Embodiment 1: see Fig. 1, LC inductive-capacitive ballast of the present invention, comprise working capacitor 1, low consumption (low pressure drop) Inductive ballast 2, capacitor 4 is also connected in the two ends of low consumption (low pressure drop) Inductive ballast (or common Inductive ballast) 2.Gaseous discharge lamp 5, except high-pressure mercury lamp, according to different lamps, then uses different starting components (starting component is attached not shown at this).After the circuit for lamp of Fig. 1 is connected with the mains and is lighted by lamp, due to LC ballast work time, supply voltage lags behind lamp current in phase place, when current over-zero supply voltage can not be used for lamp repeat ionization, lamp repeat ionize the voltage that fires again provided by the voltage at mutual capacitance 1 two ends.Before there is no capacitor 4, the voltage at mutual capacitance 1 two ends just can will be added on discharge lamp through low consumption (low pressure drop) Inductive ballast (or common Inductive ballast) 2, inductance has the characteristic hindering electric current to rise, so the zero passage place of current waveform forms a curved ditch when lamp current zero passage.When capacitor 4 and when being connected in the two ends of low consumption (low pressure drop) Inductive ballast (or common Inductive ballast) 2, when lamp current zero passage, the voltage at mutual capacitance 1 two ends is directly added on gaseous discharge lamp 5 by capacitor 4, and lamp current waveform is improved.The present embodiment is single-ended 70W ceramic metal helide lamp, and capacitor 4 is preferably 0.22 μ F.Fig. 5 is the comparison of wave shape of modulating voltage, lamp current, and I1, U1 are the waveform of existing LC inductive-capacitive ballast modulating voltage, lamp current.I2, U2 are the waveform of LC inductive-capacitive ballast modulating voltage of the present invention, lamp current.As seen from the figure, I1 obviously has distortion when zero passage, causes the voltage that fires again of U1 lamp to diminish.The waveform of I2 is sinusoidal wave substantially, thus lamp to fire voltage higher.
Embodiment 2: see Fig. 2, in the circuit structure schematic diagram of the LC inductive-capacitive ballast of Fig. 2, its circuit theory is substantially identical with Fig. 1 with circuit structure, and difference is: after resistance 3 and electric capacity 4 are connected, be connected in the two ends of low consumption (low pressure drop) Inductive ballast (or common Inductive ballast) 2.The effect of resistance 3 is the current waveforms separating kind lamp further, and the resistance of its resistance is preferably 600 Ω.
