Patents by Inventor Hans L. G. Harmgardt

Hans L. G. Harmgardt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8004210
    Abstract: The LED replacement for low voltage lamps has a plurality of LED lights disposed in a housing capped by a multifaceted reflector to provide lighting having comparable lighting characteristics to non-LED sourced low voltage lamps. Power conditioning solid state circuitry is disposed in the housing and provides the LED lights with a regulated excitation voltage source. The power conditioning circuitry has at least one ceramic capacitor in parallel with output leads of a power supply for the lamp. A zener diode pair having anodes connected together is disposed in parallel with the ceramic capacitor. The power conditioning circuitry is disposed in advance of a voltage rectifier and filter bank, whose output is provided to a voltage regulator that provides regulated DC voltage to the LED light sources. Output of the voltage regulator is modulated by thermal protection circuitry that throttles the LEDs off responsive to lamp overheating.
