BiliSoft Light Box
The light box contains the LED module, a power supply, a cooling system, and an overheating
protection. The universal power supply allows the unit to be supplied via any standard AC
main power source at either 50 or 60 Hertz that has voltages in the range of 90 to 264 V~.
The LED module produces a very narrow bandwidth of light with no appreciable amount of
ultraviolet or infrared light. The light box is cooled by a fan, and a thermal cutout switch
located on the LED module protects the light box from overheating. The LED module in the
light box is activated only when the fiber optic cable is plugged into the system.
Component/Control Function
1. Standby Switch – Turns the
unit on/off. The green light on
the switch indicates that the
standby switch is turned on
and the unit is powered.
2. Hour Meter – The non-
resettable hour meter runs
whenever the fiberoptic light
pad is illuminated. If the
fiberoptic cable is not fully
inserted into the light box, the
LEDs are automatically shut off
and the hour meter does not
run. Note : The hour meter is
provided to track LED life and
is not intended to be used to
measure therapy durations.
3. Unit Overheated Indicator –
When the red indicator light is
on, the unit has overheated.
See Troubleshooting Guide for
more details.
4. LED Module Failure Indicator -
When the red indicator light
flashes, at least one of the
three LED pairs has failed. See
the Troubleshooting Guide for
more details.
