  • Patent number: 4940921
    Abstract: A miniature, light weight, high voltage, high frequency, high power output unique ballast and a unique sealable neon lamp in a light weight, light reflective box containing the ballast for use as one of a plurality of ceiling lamps. The ballast includes a transformer with a tuned secondary due to distributed capacitance, as a result of spaced apart first and second halves of the secondary winding, particularly wound in three separate sections of a bobbin fitted on the center leg of the transformer E--E core and tightly coupled to a center tapped primary winding on the center leg of the other section of the E-core. The section of the core are separated by a high dielectric spacer which also gaps the core when the sections are placed together. An asymetrical starting circuit prevents burnout of the alternate conducting FET switching device by insuring that only a selected one FET always starts first, and the unique bobbin and secondary winding prevents breakdown in the secondary high voltage winding.
