Electronic light generating element light bulb
First Claim
1. An apparatus comprising:
- an electronic light generator having a maximum current rating; and
a circuit producing an electric signal that drives said electronic light generator, said electric signal including a pulse train that has a plurality of first pulses and a plurality of second pulses, the amplitudes of said second pulses being less than the amplitudes of said first pulses, and said pulse train being configured as successive groups of pulses that each start with one of said first pulses and that each include at least one of said second pulses, at least some of said pulses of said pulse train having a peak current value above said maximum current rating, said output signal being in excess of said maximum current rating less than ten percent of the time.

Abstract
The present system for driving an electronic light generating element, includes: (i) input terminals, (ii) an input circuit coupled to the input terminals and operable to convert a sinusoidal signal to a signal independent of negative current attributes, (iii) a switch control circuit coupled to the input circuit and operable to generate a switching signal having pulses, and (iv) a switching element coupled to the input circuit and the switch control circuit. The switching element is operable to generate an output signal formed as a series of bursts having peak amplitudes above a maximum forward current rating for a duty cycle less than a maximum operating duty cycle over which an electronic light generating element may be catastrophically damaged in response to the signal independent of negative current attributes and switching being applied to the switching element. The output signal is applied to the electronic light generating element to produce light.
