Latest Patents

One of Whitt's latest patents is an electronic ballast having current waveform control within the half wave. This invention includes a method for controlling current through a lamp to produce various current waveforms. The ballast samples and adjusts the current on a micro-second time scale within each half-cycle of the current waveform. It accommodates different lamp types, provides arbitrary current waveforms, and operates a lamp at multiple power levels. Additionally, it adjusts the current waveform as the lamp ages to minimize luminous flux loss caused by darkening of lamp walls and changes in lamp chemistry. Another significant patent is the aggregate ignition method in high-frequency metal halide lamps. This high-frequency ballast comprises a controller, a switch, and an oscillator. The ignition method includes enabling the oscillator to provide the lamp with a pulse train of rapid ignition pulses, cooling for a period, and providing an additional pulse train if necessary to ignite the lamp.
