‧The degrees of unbalance： ＜10%
‧The ratio of wave height：＜√2 ±10%
*1)Invert vender : SUMIDA , mode : IV11145T
If the waveform of light up-driving is asymmetric, the distribution of mercury inside the
lamp tube will become unequally or will deplete the Ar gas in it. Then it may cause the
abnormal phenomenon of lighting-up. Therefore, designers have to try their best to forfill the
conditions under the inverter designing-stage as below:
A：The degrees of unbalance =︱Ip – I-p︱/ Irms ×100 (%)
B：The ratio of wave height = Ip (or I-p) / Irms
