摘要： An electronic ballast has control circuitry to operate a gas discharge lamp in both full and dimmed illumination modes. A dimming controller serves as the mechanism to permit a selection between full and dimmed illumination modes. The dimming controller signal has a dimming request range which describes the range of dimming controller signal magnitudes. The electronic ballast also includes a full power circuit having a power control coupled to the dimming controller output to receive the dimming controller signal. The full power circuit also has a full power output that can couple to the lamp. When the full power circuit receives the dimming controller signal, via the power control, and the dimming controller signal is not in the dimming request range (i.e. the full illumination mode has been selected), the full power circuit generates a full power signal capable of driving/operating the lamp(s) in the full illumination mode. A filament heating circuit has a heating input coupled to the reduced power circuit, to receive the reduced power signal, and a heating output that can couple to the filaments of one or more lamps. When the reduced power signal is present, the filament heating circuit generates and provides a filament heating signal to the filaments, via the heating output. The filament heating signal maintains the temperature of the filaments when the lamp(s) are operated in the dimmed illumination mode. Further, the filament heating signal is responsive to the reduced power signal.

摘要： A constant current source mirror tank dimmable ballast operates multiple high impedance lamps in a stable and balanced manner. The dimmable ballast has an inverter connected to two third-order resonant circuits. These third-order resonant circuits dominate the transfer function of the ballast circuits. Consequently, changes in the impedance of the lamp do not affect the current output to the lamps.

摘要： A step dimming interface is utilized to operate a load such as a gas discharge lamp. The dimming interface has first and second switches for determining when the gas discharge lamp operates at either a normal power level or a dimming power level. A rectifier circuit is connected to a control signal production circuit. By manipulating the first and second switches, the rectifier sends either a full-wave rectified signal or a half-wave rectified signal to the control signal production circuit which determines the output of the control signal production circuit. The control signal production circuit may be connected to an electronic ballast which varies the power level of the lamp according to this output.

摘要： The present invention is an overvoltage protection and automatic re-strike circuit for an electronic ballast. The electronic ballast has an inverter, a shut-down circuit, a safety circuit, a monitoring circuit, and an overvoltage protection circuit. The inverter provides an appropriate alternating current power supply to operate the lamp. The shut-down, safety, monitoring, and overvoltage protection circuits are coupled to the inverter and provide the overvoltage protection and automatic re-striking functions. During an overvoltage condition, the overvoltage protection circuit will temporarily disable the inverter. Subsequent to the overvoltage condition, the overvoltage protection circuit permits the inverter to attempt to re-ignite the lamp. After a predetermined number of unsuccessful re-ignition attempts, the safety circuit will permanently disable the inverter to avoid damage to the ballast.

摘要： A power line communication system communicates a ballast dimming level to an electronic ballast over an AC power line. A power line controller is operable to generate the ballast control signal and to insert that signal on the AC power signal being transmitted over the AC power line. A power line receiver receives the AC power signal and extracts the ballast control signal from the AC power signal to generate the dimming level signal corresponding with the desired ballast dimming level. To insert the ballast control signal on the AC power signal, the power line controller has a transformer coupled to the signal pattern circuit. The secondary winding of this transformer is connected in series with the AC power line to insert the ballast control signal on the AC power signal. This AC power signal is then transmitted to the electronic ballast. To extract the ballast control signal out of the AC power signal, the power line receiver has a resonant circuit connected in series with the AC power line. The resonant circuit should be tuned to transmit the ballast control signal and to filter out the AC power signal. A dimming level sensing circuit then senses the signal pattern on the ballast control signal and generates a dimming level signal corresponding to the desired ballast dimming level.

摘要： A modular electronic ballast is provided for powering a fluorescent lamp. A motherboard is configured to receive an AC input signal, one or more supplemental input signals and a feedback signal from the lamp. A ballast control circuit generates an output signal for an oscillating inverter driving the lamps. A daughter card is coupled to the motherboard and selected from a plurality of daughter cards, each configured to provide a dimming control signal having predetermined characteristics and readable by the control circuit. The daughter cards are collectively configured to provide dimming control signals in response to each of a line-coupled demand response interface, one or more digitally addressable interfaces, analog dimming signals received via said supplemental communications bus, and three-wire phase control signals received via said AC line and said supplemental communications bus. The motherboard is configured to interchangeably receive any one of the daughter cards. The ballast control circuit is effective to generate output signals in response to the feedback signal, dimming control signal and a predetermined lamp output value.
