Flicker preventing apparatus of fluorescent lamp

摘要

A fluorescent lamp (L) controlling circuit reduces and/or prevents a fluorescent lamp (L) from suddenly flickering when a power switch (S/W) is turned on and/or off. Switching operation of a switch that supplies a direct current voltage to the fluorescent lamp (L) is restricted during a transient period to delay a reset signal so that undesired flicker of the fluorescent lamp (L) can be reduced and/or prevented.
