Abstract:
1. A circuit for driving an electronic light generating element, said circuit comprising: an input circuit coupled to said input terminals and operable to convert a sinusoidal signal to a signal that is independent of negative current attributes; a switch control circuit coupled to said input circuit and operable to generate a switching signal having pulses; and a switching element coupled to said input circuit and said switch control circuit and operable to generate an output signal formed as a series of bursts, at least one of the series of bursts having a peak amplitude above a maximum forward current rating of the electronic light generating element, and being applied to the electronic light generating element to produce light, and each said burst having a frequency sufficiently high so that a human eye is incapable of noticing flicker in the light produced by said electronic light generating element.
