A DIMMING CIRCUIT IN SELF-EXCITED ELECTRONIC BALLAST FOR ELECTRODELESS FLUORESCENT LAMPS

摘要

The novel dimming circuit using intermittent oscillation in the self-excited electronic ballast for electrodeless fluorescent lamps has been presented. In the experiment at 2.65MHz, the proposed circuit controls illuminance of the electrodeless fluorescent lamp from 100% to under 5% without flicker.
