  • Anti-Striation Circuit For A Gas Discharge Lamp Ballast
    Publication number: 20080129216
    Abstract: An anti-striation circuit employs an inverter topology including a pair of electronic switches (Q, M) that are switched between a conducting state and a nonconducting state in an alternating manner to apply an asymmetrical voltage waveform across one or more lamp (LP) to thereby control a flow of an asymmetrical current waveform (iacc) through lamps (LP). To eliminate, if not minimize, visible striations in the lamp(s) (LP), the impedances of an asymmetrical driver as connected to the control inputs (B, G) of the electronic switches (Q, M) may be unequal, and/or the impedances of an asymmetrical driver as connected to the current paths (C-E, D-S) of the electronic switches (Q, M) may be unequal. Additionally, the current gains of the electronic switches (Q, M) may be unequal, and a DC current may flow through the lamp(s) (LP).

  • Safety control circuit for detecting the removal of lamps from a ballast and reducing the through-lamp leakage currents
    Patent number: 6051940
    Abstract: A series resonant ballast safety control circuit for controlling the operation of a ballast when a lamp is removed from a lamp fixture. The safety control circuit senses a diode clamp current and activates a transistor to ground one of the terminals of a dimming control circuit. The dimming control circuit reduces the duty cycle of one of the inverter transistors to decrease the available output voltage and reduce the through-lamp leakage current to safe levels. Once the lamp is replaced in the lamp fixture, the safety control circuit no longer controls the dimming control circuit and the ballast returns to normal operation. In another embodiment, the safety control circuit is used with a boost power factor correction circuit in a non-dimming ballast system to reduce the current provided to the lamp load.
