LUMINAIRE STARTING AID DEVICE

摘要

A starting aid for a luminaire includes a trigger circuit for supplying a trigger voltage pulse to a lamp in response to the presence of a line voltage signal supplie d by a photodetector, a feedback circuit for detecting the lamp voltage and means, responsive to the line voltage signal and the feedback circuit, for comparing the voltage on t he lamp to a nominal voltage level for disabling the trigger circuit and terminating the trigger voltage pulse in the presence of a lamp cycling or lamp out condition.
