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 comprises an inverter having a transformer comprising a core, a primary winding, and a secondary winding for connecting to a lamp and providing voltage thereto. The ballast includes a fault condition detection circuit connected to the inverter for disabling the inverter to discontinue energization of the lamp when a fault condition occurs. The fault condition detection circuit comprises an other primary winding wound on the core of the transformer for receiving a voltage signal proportional to a voltage across the secondary winding, a voltage blocking circuit connected to the other primary winding for receiving the voltage signal from the other primary winding, and a capacitor connected between the voltage blocking circuit and ground potential. The voltage blocking circuit is configured to selectively conduct and block the received voltage signal as a function of the frequency of the received voltage signal.

摘要： A ballast for dimming a lamp is provided. The ballast includes an inverter circuit for providing a lamp current for energizing the lamp and a dim interface for receiving an input indicative of a selected lighting level. A control circuit is connected to the dim interface for generating a pulse-width-modulated signal having a duty cycle corresponding to the selected lighting level. A switching network is connected to the control circuit for receiving the pulse-width-modulated signal. The switching network operates between a conductive state and a non-conductive state as a function of the pulse-width-modulated signal. An impedance device is connected across the switching network and is configured for connecting in series with the lamp so that the impedance device receives the lamp current when the switching network is operating in the non-conductive state and the lamp current bypasses the capacitor when the switching network is operating in the conductive state.
