An electronic ballast having end of lamp life and overheating protection, and
automatic reignition and multiple striking capabilities includes AC/DC rectifier,
PFC/boost, inverter, and ballast protection and control circuits. The ballast protection
and control circuit is operable to place the ballast in a protected state when
the lamp load connected to the ballast reaches an end of lamp life condition or
the ballast overheats. The ballast protection and control circuit also automatically
ignites the lamp load when it is connected to the ballast and generates multiple
striking attempts for hard to strike lamp loads. The ballast may be connected to
AC or DC power sources and different types of lamp loads, and may include various
different types of inverter circuits.
