METHOD TO PREVENT SPURIOUS OPERATION OF A FLUORESCENT LAMP BALLAST
摘要:
A ballast adapted to power a fluorescent lamp as a function of a variable input signal, includes a power stage for providing power to a fluorescent lamp; a control circuit for controlling the power stage as a function of the variable input signal; a control circuit power supply for supplying control power to the control circuit; and a monitor and enabling circuit which permits the ballast to provide power to the lamp only when characteristics of the variable input signal meet predetermined criteria.
