Note3
Note1: The value is the characteristic of lamp. The starting voltage of inverter should be lower than the value. But
the possibility of not lighting exists by the lower voltage, so the suitable voltage should considered by the
test .
Note2: The asymmetric ratio of working waveform for lamps (Lamp voltage peak ratio, Lamp current peak ratio
and waveform space ratio) should be less than 5% (See the following figure). If the waveform is asymmetric, DC
(Direct current) element applies into the lamp. In this case, a lamp lifetime may be shortened, because a
distribution of a lamp enclosure substance inclines toward one side between low voltage terminal (Cold terminal)
and high voltage terminal (Hot terminal).

Pa: Supply voltage/current peak for positive, Pb: Supply voltage/current peak for negative
Sa: Waveform space for positive part, Sb: Waveform space for negative part
Note3: Recommended value of “FO” is as following.
FO = 1/4 x 1/th x (2n-1) n: Natural number (1, 2, 3 ……)
