A proper cooling solution such as a heatsink is critical for operating UV LEDs. UV LEDs dissipate heat through the backside, so it is important to have a suitable cooling solution with good thermal dissipation made from materials such as copper or aluminum and to apply thermal interface material between the LED and heatsink. UV LEDs with lower power consumption can be passively cooled through convection with heatsinks. High power UV LEDs with high electrical consumption may require fan-cooled heatsinks.

Finally, liquid cooling is recommended for high power UV LEDs that cannot be cooled with forced convection from fans. Please contact the Violumas team to learn more about designing an appropriate heatsink for your specific application.
