rLuminous lamp
The light source of the projector is a high-pressure mercury lamp.
A high-pressure mercury lamp has the following characteristics.
f The luminance of the luminous lamp will decrease by duration of usage.
f The luminous lamp may burst with a loud sound or have its service life shortened because of shock, chipping, or
degradation due to cumulative runtime.
f The luminous lamp life varies greatly depending on individual differences and usage conditions. In particular,
continuous use for 12 hours or more and frequent off/on switching of the power greatly deteriorate the luminous
lamp and affect the luminous lamp life.
f In rare cases, the luminous lamp burst shortly after the projection.
f The risk of bursting increases when the luminous lamp is used beyond its replacement cycle. Make sure to
replace the lamp unit according to the proper replacement time . (“When to replace the lamp unit” (
Æ
page
154) and “How to replace the lamp unit” (
Æ
page 154))
f If the luminous lamp bursts, gas contained inside of the luminous lamp is released in a form of smoke.
f It is recommended to store replacement lamps for contingency.
