  • Dimmable induction RF fluorescent lamp with reduced electromagnetic interference
    Patent number: 10128101
    Abstract: A dimmable induction RF fluorescent light bulb comprising a power coupler with reduced extraneous electromagnetic radiation wherein a dimming facility utilizes burst-mode dimming that periodically interrupts the high frequency voltage and current to the power coupler with an off period and an on period in order to reduce the power being delivered to the power coupler wherein the off period is shorter than the time required for an electron density of the discharge within the lamp envelope to substantially decrease.
    Type: Grant

  • INDUCTION RF FLUORESCENT LAMP WITH REDUCED ELECTROMAGNETIC INTERFERENCE
    Publication number: 20140145603
    Abstract: An induction RF fluorescent lamp that is able to replace an ordinary reflector-type incandescent lamp, both in its ability to screw into a standard incandescent lamp socket and to have the general look of the ordinary reflector incandescent lamp, but with all of the advantages of an induction lamp, and comprising a power coupler with conductive material in contact with the power coupler to reduce extraneous electromagnetic radiation emanating from the power coupler.
