Manufacturer:ST Description: To provide long life and to insure soft-starting of the lamp, the cathodes must be pre- heated so that their hot resistance is approximately three to four times that of the cold resistance value. This is performed by using a three step start-up sequence; the three steps being three oscillator frequency settings. The oscillator is started at a frequency well above the resonant point of the LC circuit formed by inductor L1 and capacitor C9. This is done to insure that the initial voltage applied across the lamp is below the strike potential. The second frequency step, below step 1, was chosen to provide a current through the cathodes large enough to heat them in the pre-heat time while also maintaining the voltage across the lamp below the strike potential. The third step is to move the oscillator to the final running frequency. At this point the voltage across the lamp becomes large enough to strike the arc and the resonant point of the circuit shifts lower and the current in the lamp is limited by the inductor L1. |
