摘要：

High power near-UV LEDs, with wavelengths from 365nm to 410nm, were realized with an external quantum efficiency from 12% to 45% for 365nm and 410nm, resp. We show that the vertical LED design, coupled with the Silicon sub-mount package, gives very good reliability that is suitable for many high power epoxy and polymer curing applications. UV LEDs are proven to be a good replacement for high power mercury lamps currently used in the market.
