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 +/-
3) Definition of the lamp life time： Luminance (L) under 50% of specification starting lamp
4) The condition of Turn-on and Turn-off operation is as below:
5) It is necessary to consider the maximal value when design inverter，in order to asure lighting.
6)
It should not have motion fail when starting lamp voltage is lower than 130% of the initial value
voltage or starting lamp voltage is more than 130% of the initial value
the equation of power comsuption
b.If the lamp frequency can be maintain in 50~60KHz, the better charactristics of the electrical
c.If the operating frequency is 40~80 KHz, the life time and the reliability of the lamp will not
d.Lamp frequency of inverter may produce interference with horizontal synchronous
a. Lamp current is 7.5mA
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.
10% except hue.

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.
