Abstract: A method for operating a fluorescent lamp (5) having a nominal power (WLa) and stabilized with an EM ballast (B) comprises the steps of during normal operation, short-circuiting the lamp during a closing time interval (CTI) during each current period in order to operate the lamp at a reduced power. The method comprises the step of detecting whether the lamp is stabilized by means of an inductive ballast or by means of a capacitive ballast. If it is found that the ballast is capacitive, the timing of the closing time interval (CTI) is set such that the closing time interval (CTI) has a first closing time segment (CTS1) immediately before a zero-crossing of the current, having a first duration (Δ1) higher than zero, and a second closing time segment (CTS2) immediately after said zero-crossing of the current, having a second duration (Δ2) higher than zero.

A resistive heater is located adjacent to at least one of the arc tube and the exhaust tube. A power supply circuit is operatively coupled with the resistive heater. When the fluorescent lighting device is switched from an OFF state to an ON state, the power supply circuit temporarily energizes the resistive heater, thereby heating the at least one of the arc tube and the exhaust tube while the resistive heater is energized, and automatically de-energizing the resistive heater after said heating.

Abstract: A current-preheat electronic ballast includes an AC-to-DC converter, a controlling unit, an auxiliary voltage generator, and an inverter. The inverter is connected with the DC bus for converting a high DC voltage into an AC output voltage and generating a resonant current and a lamp filament current to a lamp group. The inverter includes a resonant circuit and a resonant capacitor adjusting circuit. The resonant circuit provides electric energy required to preheat the lamp group. The resonant capacitor adjusting circuit judges whether the inverter is enabled according to the detecting element. After the inverter has been enabled for a delayed time, two high-voltage switching terminals of the resonant capacitor adjusting circuit are correspondingly conducted or shut off, so that an equivalent resonant capacitance value of the resonant circuit is changed and a voltage drop across two ends of a lamp filament of the lamp group is changed.

Abstract: A local minimum of a current monitoring signal is identified by a starter unit that turns off a fluorescent lamp without using a wall switch. Closing a main switch in the starter unit stops an illuminating current from flowing through a gas in the lamp. The local minimum of the current monitoring signal is reached when an increasing valid sample is identified following four valid samples. A sample is valid if it does not differ from the preceding valid sample by more than a threshold difference based on known properties of the signal. By skipping invalid samples, the local minimum is accurately determined to have been reached despite transient noise spikes in the signal that would trip any voltage threshold used to locate the local minimum. When the main switch is opened at a predetermined time after the local minimum, the illuminating current does not again flow through the gas.

Abstract: An electronic ballast for driving a gas discharge lamp includes a power converter for generating a DC bus voltage, where the bus voltage is controlled to different magnitudes during different operating modes of the ballast. The ballast comprises a control circuit that is coupled to the power converter for adjusting the magnitude of the bus voltage to a first magnitude when the lamp is off, to a second magnitude when preheating filaments of the lamp, and to a third magnitude when the lamp is on. The control circuit is also operable to preemptively adjust the magnitude of the bus voltage prior to changing modes of operation. For example, when turning the load on, the control circuit first adjusts a power-conversion-drive level of the power converter to begin adjusting the magnitude of the bus voltage towards a predetermined magnitude, and then waits for a predetermined time period before attempting to turn the load on.
