Latest Patents
One of his latest patents is the "Dimmable Instant Start Ballast." This invention provides dimming control over a range of operation without requiring external cathode heating for the lamps driven by the ballast. The design includes an interface circuit that features a winding inductively coupled to an inverter circuit. By varying the input voltage across control leads, the apparent inductance of the winding is adjusted, which in turn affects the switching frequency of the inverter circuit. This innovation allows for dimming without the need for multiple ballasts or external heating.
Another significant patent is the "Auxiliary Lighting Circuit for High Intensity Discharge System." This lighting system includes an auxiliary circuit designed for use with an electronic HID ballast. It features a power supply that provides power to a high-intensity discharge lamp via an electronic ballast. The system also includes a ballast power sensing component that determines the power drawn by the electronic ballast and converts it to a scaled voltage. This voltage triggers a lamp driver component to power an auxiliary lamp when a specific threshold is reached, ensuring that the auxiliary lamp operates within a predefined power range.
