Latest Patents
John I Daspit holds a patent for a "Switched Mode Electrode Ballast." This electronic ballast circuit is designed for operating high-intensity gas discharge tubes, including high-pressure sodium, high-pressure mercury, and metal halide tubes, as well as ordinary fluorescent tubes. The preferred embodiment of his invention features an inductance and capacitance connected in series with the load across the DC supply. A solid-state switch is positioned between the junction of the inductance and capacitance and the other side of the load, along with a control circuit that operates the switch at a high frequency, such as 20,000 hertz. Alternative embodiments that omit the capacitance and utilize a transformer for the inductance are particularly suited for less expensive units and emergency lighting applications. His power supply circuits, which operate in conjunction with the previously mentioned switch, provide regulation of lamp output during start-up and compensate for changes in supply voltage coordinated with lamp aging.
