Abstract:
1. An adapter assembly for converting a low frequency fluorescent light fixture to a high-frequency fluorescent light fixture, the low frequency fluorescent light fixture having a low-frequency ballast and at least two tombstone sockets for connecting to and retaining a fluorescent lamp, the fluorescent lamp having a tube forming a light source upon being energized and double-prong terminals at opposite ends of the tube, the adapter assembly comprising: an elongate adapter body having opposite ends spaced at a standard distance corresponding to a distance between the opposite ends of the fluorescent lamp; two double-prong terminals respectively disposed at said opposite ends of said adapter body, said double-prong terminals being disposed at and corresponding to standard double-prong terminals of the low-frequency fluorescent lamp; a circuit forming a high-frequency ballast configured to upconvert a low-frequency output signal of the low-frequency ballast to a high-frequency input signal for energizing a high-frequency fluorescent light fixture, said high-frequency ballast having an input side connected to said double-prong terminals at said opposite ends of said adapter body and an output side; and two sockets at said opposite ends of said elongate adapter body electrically connected to said output side of said high-frequency ballast and disposed to engage with and retain double-prong terminals of a high-frequency fluorescent lamp.
