摘要： A three light level electronic ballast, and methods of operating lamps at three light levels, are provided. The ballast includes a rectifier, a power factor correction circuit, an inverter circuit, a first circuit, a second circuit, and a control circuit. The rectifier receives an AC voltage signal and produces a rectified voltage signal, which the power factor correction circuit receives and uses to provide a corrected voltage signal. The inverter circuit receives the corrected voltage signal and provides an energizing signal to power at least two lamps. The first circuit selectively reduces the current applied to the lamps by the energizing signal. The second circuit selectively prevents the second lamp from being energized by the energizing signal. The control circuit controls the first circuit and the second circuit.

摘要： A ballast for driving one or more lamps includes a controller and a current reduction circuit for accelerating a controller reset. Upon detecting a fault, the controller disables the ballast for a preset period of time, and resets. The controller additionally resets when the ratio of a supplied second value to a supplied first value falls below a threshold value. The current reduction circuit reduces the supplied second value in less than the preset period of time, such that the ratio falls below the threshold value and the controller resets. An emergency lighting system includes the ballast as a primary ballast, a backup ballast, and a primary power source. The controller detects a fault if the primary power source de-energizes and the backup ballast disconnects the one or more lamps from the primary ballast. The current reduction circuit accelerates the reset of the controller when the primary power source de-energizes.

The impedance component is connected in parallel with the feedback transformer, and is operated by the control circuit. When the control circuit enables the impedance component, the switching circuit operates in a first frequency range, and a first lamp current is provided. When the control circuit disables the impedance component, the switching circuit operates in a second frequency range, and a second lamp current is provided. The first frequency range is lower than the second, and the first lamp current is greater than the second.

摘要： A restart circuit for causing an electronic ballast to perform a restart in response to reconnecting any lamp of a multiple lamp configuration of the electronic ballast to the electronic ballast is disclosed. The electronic ballast includes a filament health check circuit for providing a first current through a monitored filament of the lamps to a controller of the ballast. The controller restarts the electronic ballast when a determined ratio of the first current to a reference current indicates that the monitored filament has been disconnected or broken (i.e., the first current substantially decreases) and is subsequently replaced or reconnected to the ballast (i.e., the first current returns to a predetermined level). The ballast further comprises a dv/dt circuit for reducing the first current for a transient time period in response to reconnecting a filament other than the monitored filament to the ballast, causing the controller to restart the ballast.
