Cool light output: A dichroic-coated reflector reflects only the useable UV wavelengths of light through the light guide. The harmful high-temperature infrared is diverted away from the material being cured. A secondary in-line filter further reduces heat for extremely sensitive applications.

Long lamp life: The SunSpot SM UV light curing system provides exceptional lamp life due to several design features:

• The lamp is mounted vertically, which allows the arc to fall straight in line with gravity. This prevents the arc from wandering into the quartz envelope and overheating it and ensures the arc strikes the conical anode equi-radially, preventing uneven electrode erosion.

• The lamp is constructed with an extra-heavy blunt-tipped anode electrode, which does not degrade quickly over time (like the needle-shaped electrodes of traditional arc lamps).

• Airflow is carefully channeled to provide symmetrical cooling of the lamp, which ensures long end seal life and prevents damaging hot spots and arc sputtering.

Lamp power regulation: Our patented Power-Plus Lamp Driver maintains constant lamp power regardless of variations in AC line input or lamp voltages. This regulation provides for stable light output, repeatable curing times and longer lamp life.

Timer-controlled shutter: An accurate 1–99-second, foot-pedal-controlled exposure timer and shutter free the operator’s hands for other tasks. The timer can be switched from timed to manual mode for operator control of curing duration.

Convenient Front Panel Indicators: A front panel hour meter tracks lamp age, allowing for consistent lamp replacement scheduling, and a lamp-ready LED notifies the user when warm-up is complete.

Quick-change lamp: The system’s side lamp access panel is easily removed by loosening a single thumbscrew, making lamp or reflector changes possible in as little as one minute.

Forced air cooling: The quiet dual-fan cooling system directs air to critical system components, ensuring cool operation and high system reliability.

Safety interlocks: Two unique safety interlocks provide maximum protection during operation and maintenance procedures. The first automatically forces the shutter closed if the light guide is removed, preventing operator exposure to high-intensity light. The second immediately removes system AC input power when the lamp access panel is opened, protecting the operator from high voltages or high-intensity light present behind the panel.
