The usage limit of the UV irradiation lamp
Long-hours use of the UV irradiation unit will make the UV irradiation lamp,
in accordance with this, the irradiation power of the lamp will also decline.
You can calculate the usage limit of a UV irradiation lamp by the following
equation.
The usage limit of a UV irradiation lamp = 2000 hours ÷ (irradiation time
of one workpiece)
÷ (number of workpieces processed in a day)
When the UV irradiation lamp use period reaches the calculated value, replace
the UV irradiation lamp.
The number of the UV irradiation lamps mounted in the machine is ten. When
one of the lamps reaches its usage limit, replace all of them.
