Note (1) Lamp current is measured by utilizing AC current probe and its value is average by measuring master
and slave board.
Note (2) The lamp starting voltage VS should be applied to the lamp for more than 1 second after startup.
Otherwise the lamp may not be turned on.
Note (3) The lamp frequency may produce interference with horizontal synchronous frequency of the display
input signals, and it may result in line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronous frequency and its harmonics as far as
possible.
Note (4) The lifetime of lamp can be defined as the time in which it continues to operate under the condition
Ta = 25 ±2 oC and IL = 7 mArms until one of the following events occurs:
(a) When the brightness becomes or lower than 50% of its original value.
(b) When the effective ignition length becomes ≦ 80% of its original value. (The effective ignition
length is a scope that luminance is over 70% of that at the center point.)
