Discharge lamp lighting device and lighting apparatus

摘要

A timer unit determines status conversion timing for performing a shift from pre-heating status. A control unit determines on/off timing of switching elements of inverter circuit (2) based on control signal from timer unit. An output unit outputs preset status signal based on operational status of control circuit, and lighting status. An operation setting circuit (6) inputs status signal and outputs control signal to control unit. An independent claim is also included for lighting apparatus.
