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.
