Publication number: 20130309131Abstract: Exemplary embodiments are directed to lamp ballast systems, generally including a lamp, at least one temperature sensor, a ballast and a processor. The at least one temperature sensor can be positioned proximate to the lamp or incorporated into the lamp. The ballast provides an electrical current to the lamp. The processor receives a sensed temperature from the at least one temperature sensor and, in response to the sensed temperature, directs a control signal to the ballast to regulate the electrical current provided to the lamp to maintain the lamp at an optimal operating temperature. Exemplary embodiments are also directed to methods of maintaining a lamp at an optimal operating temperature, generally including providing a lamp ballast system, receiving a sensed temperature, and directing a control signal to the ballast to regulate the electrical current provided to the lamp to maintain the lamp at the optimal operating temperature.Type: ApplicationFiled: May 20, 2013Publication date: November 21, 2013Inventor: Rolf Engelhard
