FLUORESCENT LAMP INFORMATION DETECTION SYSTEM AND METHOD

摘要

A fluorescent lamp information detection system and method including an information detection system for fluorescent lamps, the system including inverters (120), each of the inverters (120) being operably connected across the high end filament of one of the fluorescent lamps; a controller (130) responsive to a lamp information signal (142) to determine a lamp condition of each of the fluorescent lamps; and lamp information detection circuits (140). Each of the lamp information detection circuits (140) includes a series resistance circuit operably connected between a DC voltage and ground, the series resistance circuit operably connecting in series a first resistance, the high end filament, a second resistance, and a third resistance; a capacitance operably connected in parallel with the third resistance; and a voltage tap operably connected between the second resistance and the third resistance, the voltage tap providing the lamp information signal (142).
