摘要： An electronic ballast for driving a gas discharge lamp comprises a measurement circuit (170) for measuring a lamp current flowing through the lamp and a lamp voltage produced across the lamp. The ballast comprises a first winding (260) magnetically coupled to a main transformer of an inverter circuit, and a second winding (262) magnetically coupled to a split or coupled resonant inductor (240) of a resonant tank circuit (150). The first and second windings (260, 262) are coupled in series electrical connection to generate a voltage representative of the magnitude of the lamp voltage. The ballast further comprises a current transformer (270) having primary windings coupled in series with the electrodes of the lamp. The measurement circuit (170) integrates the current conducted through secondary windings of the current transformer (270) only during every other half-cycle of the lamp voltage to generate a control signal representative of the magnitude of the lamp current that is in-phase with the lamp voltage.

摘要： A ballasted lamp socket for a gas discharge lamp, such as a compact fluorescent lamp, is adapted to replace an Edison screw-in lamp socket in a ceiling mounted light fixture, or a table or floor lamp. The ballasted lamp socket comprises a lamp-receiving portion adapted to be coupled to the gas discharge lamp, an enclosure mechanically coupled to the lamp-receiving portion, a dimming ballast circuit electrically coupled to the lamp-receiving portion and housed within the enclosure, and first and second electrical connections. The ballast portion is adapted to receive an AC line voltage and to generate a high-frequency AC voltage for driving the gas discharge lamp and controlling the light intensity of the gas discharge lamp between a high-end intensity and a low-end intensity. The first and second electrical connections are operable to receive the AC line voltage and to provide the AC line voltage to the ballast circuit.

摘要： A method of striking a gas discharge lamp Involves the steps of generating a high-frequency square-wave voltage having an operating frequency, generating a sinusoidal voltage from the high-frequency square-wave voltage, controlling the operating.frequency to a low-end frequency, and increasing the amplitude of the sinusoidal voltage during successive pulse times and then decreasing the amplitude of the sinusoidal voltage towards the low-end amplitude at the end of each of the successive pulse times until the lamp has struck, where the length of each of the successive pulse times being greater than the length of the previous pulse time. A maximum amplitude of the sinusoidal voltage during each pulse time may be greater than a maximum amplitude of the sinusoidal voltage during the previous pulse time.

摘要： A dimmer switch for controlling the intensity of a dimmable screw-in compact fluorescent lamp provides smooth dimming of the fluorescent lamp and prevents flickering of the lamp due to multiple re-strikes. The dimmer switch prevents multiple re-strikes by avoiding multiple firings of a controllably conductive switching device of the dimmer circuit by limiting the high-end light intensity of the fluorescent lamp. Specifically, the dimmer switch limits the length of a conduction interval of the controllably conductive switching device to less than approximately 75% of each half-cycle. The dimmer switch may include a user-accessible adjustment actuator for changing the dimmer switch between an incandescent operating mode and a screw-in compact fluorescent mode. The dimmer switch may also be operable to automatically change the dimmer switch between the incandescent operating mode and the screw-in compact fluorescent mode by detecting the occurrence of the multiple firings of the controllably conductive switching device.

摘要： A load control circuit, such as a light-emitting diode (LED) driver, for controlling the amount of power delivered to electrical load, such as an LED light source, comprises a regulation transistor adapted to be coupled in series with the load, and a feedback circuit coupled in series with the regulation transistor, whereby the load control circuit is able to control the magnitude of a load current conducted through the load from a minimum load current to a maximum load current, which is at least approximately one thousand times larger than the minimum load current. The feedback circuit generates at least one load current feedback signal representative of the magnitude of the load current. The regulation transistor operates in the linear region to control the magnitude of the load current conducted through the load in response to the magnitude of the load current determined from the load current feedback signal.
