Module
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:

ITEM
A：The degrees of unbalance =︱Ip – I-p︱/ Irms ×100 (%)
B：The ratio of wave height = Ip (or I-p) / Irms
