LD-22113-12
【Note 9-6】Lamp is consumables. In the following condition, the lamp life time is 20,000
hours as the reference value and it is not guaranteed in this specification sheet by
SHARP.
Lamp life time is defined that it applied either ① or ② under this condition.
※Continuous turning on at Ta = 25
o
C, I
L
= 5.5mA rms and PWM dimming 80%~5%
(IL= 9.0mArms Ta= 25℃).
①Brightness becomes 50% of the original value under standard condition.
②Kick-off voltage at Ta = −30
o
C exceeds maximum value (1700Vrms).
Lamp life time shortens according to the state of mounting and use.
In case of operating under lower temp environment, the lamp exhaustion is
accelerated and the brightness becomes lower.
Continuous operating for around 1 month under lower temp condition may reduce
the brightness to half of the original brightness.
In case of such usage under lower temp environment, periodical lamp exchange is
recommended.
【Note 9-7】The intermittent cycles is defined as a time when brightness not to become under
50% of the original value under the condition of following cycle.
Ambient temperature：−30℃
Don’t use the unsymmetrical voltage and current wave which have spike wave.
【Note 9-8】The performance of the backlight, for example life time or brightness, is much
influenced by the characteristics of the DC-AC inverter for the lamp.
When you design or order the inverter, please make sure that a poor lighting
caused by the mismatch of the backlight and the inverter (miss-lighting,flicker,
etc.) never occur. when you confirm it, the module should be operated in the same
condition as it is installed in your instrument.
Be sure to use a back light power supply with the safety protection circuit such as
the detection circuit for the excess voltage, excess current and or electric discharge
waveform.
【Note 9-9】Please make it to the structure not touching directly insulating the high voltage
part.
Please stop the circuit by the protection element such as fuses for generation of
heat and the ignition prevention, and use a flame resisting and high material for
the substrate and the resin material.
【Note 9-10】Under the environment of 10lx or less, miss-lighting delay may occur.
