| 20090309511 | Dimming fluorescent ballast system with shutdown control circuit - A ballast system for, and a method of, controlling illumination of a lamp, include a dimmer switch having an actuator settable at different settings corresponding to different output voltages across the dimmer switch, a dimming electronic ballast operatively connected to an electrical power source and to the dimmer switch for dimming the lamp upon setting of the actuator, and a shutdown circuit, preferably provided in the ballast, for measuring the output voltages across the dimmer switch, and for automatically powering the ballast off and, in turn, for turning the lamp off when one of the voltages measured by the shutdown circuit does not exceed a reference voltage that corresponds to one of the settings of the actuator. | 12-17-2009 |
| 20110043040 | Ballast For Fluorescent Emergency Lighting - An emergency ballast for a fluorescent lamp includes a rechargeable battery. The emergency ballast also includes a circuit for receiving an electrical current and providing a recommended charging voltage to the battery. The electrical current is one of two amplitudes, and the circuit provides a charge to the battery without regard to the amplitude of the electrical current. The first amplitude of the electrical current can be 120 volts, and the second amplitude can be 277 volts. The emergency ballast includes a capacitor electrically coupled to the circuit that provides an additional voltage to the rechargeable battery when the electrical current is 120 volts. The emergency ballast also includes a switch for electrically decoupling the capacitor from the circuit when the electrical current is 277 volts. | 02-24-2011 |
| 20110043041 | Sinusoidal Alternating Current Ballast For Fluorescent Emergency Lighting - A ballast for a lamp has a battery that provides direct current in response to a loss of power. The ballast has a conversion circuit that is configured to receive the direct current from the battery and convert it into alternating current that is provided to a lamp. The alternating current is substantially sinusoidal, and has a current crest factor of 1.7 or less. The conversion circuit can use a push-pull topology. The ballast can also include a cathode-heating circuit for pre-heating a cathode associated with the lamp. The cathode-heating circuit pre-heats a cathode of the lamp by increasing the current output of the conversion circuit. The ballast can also include circuitry for converting mains power to power appropriate to illuminate the lamp. | 02-24-2011 |
