Abstract:
1. A circuit for driving a lighting device having a manufacturer's specified power consumption to produce a manufacturer's specified luminosity, comprising: a transistor connected with the lighting device in series; an oscillator connected to the transistor in series to work with the transistor to generate driving pulses at a frequency that corresponds to a resonant frequency of the circuit and that is at least 50,000 Hz; a transformer connected to a power source and the oscillator in series that controls a voltage of the driving pulses; and a duty cycle controller connected to the oscillator in series that operates the pulses at a duty cycle of no more than 15%, wherein a power consumption level of the circuit is a function of the pulses' frequency and duty cycle; wherein the circuit is operating at a power consumption level based on the driving pulses' frequency and duty cycle that is no more than 75% of the manufacturer's specified power consumption to produce at least the specified luminosity.
