摘要： A power controller converts a line voltage to an RMS load voltage for a lamp, and includes a switch and a microcontroller that operates the switch to define the RMS load voltage. The microcontroller senses a load voltage of the lamp, compares the sensed load voltage to a reference RMS voltage, and operates the switch in response to the comparison so that the RMS load voltage is substantially constant at the reference RMS voltage over an operating range of the line voltage and so that the RMS load voltage decreases with decreasing line voltage at line voltages less than the operating range. The operating range of the line voltage is defined to have a minimum that is a non-zero line voltage at which a load current is a predetermined maximum. The voltage conversion circuit may be a phase clipping circuit or a pulse width modulation circuit.

摘要： A method of converting a line voltage to an RMS load voltage in a lamp includes connecting a phase-clipping circuit which includes a transistor switch and a microcontroller that operates the transistor switch to a lamp terminal. A phase conduction angle is established in the phase-clipping circuit for determining an RMS load voltage by operating the transistor switch, wherein ON/OFF periods of the transistor switch define the phase conduction angle. The method further includes sensing the load voltage, comparing in the microcontroller the sensed load voltage to a reference RMS voltage, and adjusting the ON/OFF periods of the transistor switch in response to the comparison to cause the load voltage to approach the reference RMS voltage.

摘要： A lamp includes a voltage controller that converts a line voltage to a desir ed RMS load voltage. The voltage controller is entirely within a lamp base and uses pulse width modulation to define the RMS load voltage. The voltage controller has a feed - back circuit that adjusts the RMS load voltage to a desired voltage based on a comparison to a preset reference. The voltage converter also includes a switching transistor that pulse width modulates lamp current and that is responsive to the feed-back circuit . The feed-back circuit may be included in a microcontroller that has a time-based signal source that triggers the transistor, a comparator that compares the load voltage to a reference, and a program that adjusts the time-based signal source based on the comparison so as to provide the desired RMS load voltage.

摘要： A phase-control power controller that converts a line voltage to an RMS lo ad voltage includes a fixed phase forward/reverse hybrid phase-control clipping circuit that performs phase-control clipping of a load voltage to provide an RMS load voltage. A conduction angle of the phase-control clipping circuit is defined by a time- based pulse source that triggers conduction in the phase-control clipping circuit independently of line voltage magnitude during time periods that span polarity changes of the load voltage and that are separated by intervals when conduction is not triggered. The phase- control clipping circuit includes a transistor switch whose gate receives positive polarity signals from the time-based pulse source to trigger conduction of the phase-control clipping circuit. The power controller may be in a voltage conversion circuit that converts a line voltage at a lamp terminal to the RMS load voltage usable by a light emittin g element of the lamp.

摘要： A method of operating a lamp that has a power controller connected between a terminal and a light emitting element that converts the line voltage to an R MS load voltage. An input to an analog control block is provided in the controller that is independent of a change in magnitude of the line voltage. A trigger signal from the analog control block is provided at a first frequency by charging and discharging a capacitor in the analog control block that receives the input. An initial condition of the analog control block is resetted periodically. A sync signal synchronizes th e trigger signal with a waveform of the line voltage. A load voltage is clipped based on the synchronized trigger signal to define the RMS load voltage.
