18 W Single UV LED 370nm Test with Heatsink
Here we test a single 18W UV LED with a wavelength of 370nm. The LED requires a power supply of 19V at 1A and is mounted on a metal plate to assist with heat distribution. We mounted the UV LED onto an old copper CPU heatsink and ran the UV led for a couple of hours and found the increase in temperature with the heatsink fitted was only a few degrees. Without the heatsink the lifespan of the UV LED would be shortened. This UV LED setup could be used for counterfeit note detection, security marking, curing o br, br,
