[Note ] Measuring inverter TypeCVT SIT-22FA3

If the waveform of light up-driving is asymmetric, the distribution of mercury inside the lamp

tube will become unequally or will deplete the Arm gas in it. Then it may cause the abnormal

phenomenon of lighting-up. Therefore, designers have to try their best to for fill the conditions

under the inverter designing-stage as below:

The degrees of unbalance10% The ratio of wave height√2 ±10%

Continuous

Operation

*3)

1) Lamp Current measurement method (The current meter is inserted in cold line)

2) a.Frequency in this range can mala the characterisitics of electric and optics maintain in +/- 10%

except hue.

b.If the lamp frequency can be maintain in 50~60KHz, the better charactristics of the electrical

and the optical can be presented.

c.If the operating frequency is 40~80 KHz, the life time and the reliability of the lamp will not be

affect.

d.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.

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

4) The condition of Turn-on and Turn-off operation is as below:

a. Lamp current is 8.0mA

b. Frequency is 10 sec.(on)/10 sec.(off)

c. Repeat it for 10 thousand times

d. The result of eye-etching 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.

5) It is necessary to consider the maximal value when design inverterin order to assure lighting.

6) The equation of power consumption WL=IL x VL x 2.(IL=8.0mATa=25 )

7) For keeping good lighting situation, when design the inverter, it must be considered that the voltage large than starting lamp voltage.

8) WL=IL x VL x2(IL=8.0mATa=25)

9) The Starting Lamp Voltage (VS) of inverter must be driven large than one second.

10) The output voltage of inverter (Vn) must be the same phase of between any lamps.

11) The difference in voltage between any lamps(V) must be smaller than 300V at the same time. ExampleV300VV =V1(t)-V2(t)
