His innovative approach has led to the development of a unique patent that addresses challenges in maintaining consistent lamp voltage.
Latest Patents
Ralph G Foose holds a patent for an "AC Regulator system for quartz iodine lamps." This invention effectively reduces the changes in light output from the lamps for a 40 volt change in AC line voltage from 132% to just 10%. The system utilizes a regulating pulse width modulator that is synchronized to the AC line. This synchronization allows for the development of pulse width modulated pulses that coincide with the zero crossover points of the AC line voltage. The variable leading edge of these pulses controls the firing point of semiconductor switching devices in series with the lamps. The average voltage across the lamps is sensed and used by the regulating pulse width modulator to adjust the pulse width, ensuring that the lamp voltage remains constant despite significant fluctuations in line voltage.
