The Light Sources consist of an enclosure housing, a high intensity lamp, proprietary optical platform, user
controls and indicators, and a power supply with control electronics. Cooling is provided via internal fans. In the
event that the fan(s) malfunctions or if adequate air flow is blocked and/or the internal temperature of the device
exceeds the engineering specifications, an internal thermal protection mechanism will automatically shut off
power to the lamp. After cooling, restart the Light Sources.

AMPS
The lamps are high pressure, high intensity and long life Light Sources. They are mounted into a patented lamp
fixture which is designed to allow both easy and rapid exchange in the field as well as ensuring precise alignment
to the optical platform.

ONTROL
All the electricity to the Light Source is controlled through the ON/OFF switch. Power to energize and operate the
lamp, fans, and control circuitry is provided by a custom designed, wattage regulated, switching power supply.
The operational life of the lamp and the lamp life indicator are controlled by a lamp voltage monitoring circuit.

Internal, to both the multi Link™ Port and Multi Link™ Expansion Port, are patented coupling optics and
mechanics designed to produce the highest output powers. Internal to the Light Sources are fans and heatsinks
designed to reduce temperatures at the optical coupling joints thereby minimizing the possibility of damage to
Micro Link® Fiber and fiber bundles.
