2.5 Safe Usage of LED Lamps
Caution!
Risk of product damage due to static electricity and surge voltage.
Do not touch the LED display areas.
Caution!
Risk of product damage due to moisture.
The LED lamps may absorb and hold moisture during the LED module
installation or if not used for a long time. Therefore, in such cases, the
brightness must be increased gradually during a break-in period before
setting the normal brightness.
If the LED lamps are lit with 100% brightness while moisture is retained,
the temperature will rise very quickly and the water inside the lamps will
evaporate and expand. This will cause the encapsulating resin to expand,
which may lead to separation of the boundary surface inside the LED
lamps. This separation can cause the LED lamps not to light up properly.
Lamp break-in
Configure the brightness settings as shown below with a video displayed on the
LED module. After a break-in period of approx. 3 hours, the LED module can be used
under normal conditions.
