Note (4)
CCFL inverter should be able to provide a voltage over specified value (Vs) in the above
table. Lamp units need at least Vs value shown above to ignition.
Note (5)
The voltage over specified value (Vs) should be applied to the lamp more than 1 second
after startup. Otherwise, the lamp may not be turned on. The used lamp current is the lamp
typical current.
Note (6)
The output voltage waveform and current waveform of the inverter must be symmetrical
(Unsymmetrical ratio is less than 10%). Please do not use the inverter which has
unsymmetrical voltage and current waveform, and spike waveform. The inverter design
which can provide the best optical performance, power efficiency, and lamp life should under
the following conditions.
a. The asymmetry rate of the inverter waveform should be less than 10%.
b. The distortion tae of the waveform should be within
√
2±10%.
c. The inverter output waveform should be better similar to the ideal sine wave.
