[Note ] Measuring inverter Type:M063-4
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:
The degrees of unbalance: <10%
The ratio of wave height:<√2 ±10%
A:The degrees of unbalance =︱Ip – I-p︱/ Irms ×100 (%) B:The ratio of wave height = Ip (or I-p) / Irms

[Note 2]
1.Frequency in this range can mala the characterisitics of electric and optics maintain in +/- 10% except hue.
2.If the lamp frequency can be maintain in 50~60KHz, the better charactristics of the electrical and the optical can be presented.
3.If the operating frequency is 40~80 KHz, the life time and the reliability of the lamp will not be affect.
4.Lamp frequency of inverter may produce interference with horizontal synchronous frequency,and this may cause horizontal beat on the display.Therefore, please adjust lamp frequency, and keep inverter as far from module as possible or use electronic shielding between inverter and module to avoid the interference.
[Note 3] Definition of the lamp life time Luminance (L) under 50% of specification
starting lamp voltage or starting lamp voltage is more than 130% of the initial value
[Note 4] The condition of Turn-on and Turn-off operation is as below:
a. Lamp current is 7.0mA b. Frequency is 10 sec.(on)/10 sec.(off) c. Repeat it for 10 thousand times d. The result of eye-atching of the lamp hue is normal, and can switch the lamp. It should not have motion fail when starting lamp voltage is lower than 130% of
the initial value
[Note 5] It is necessary to consider the maximal value when design inverterin order to
asure lighting.
