The LUXEON UV U1 delivers twice the irradiance power of the previous generation UV LED at 380-390 nm in a miniature 2.2 mm2 SMD package with a 5x greater power density.
Leveraging its leading expertise in chip scale packaging, Lumileds today introduced the LUXEON UV U1 LED for use in UV curing, counterfeit detection, analytical instrumentation, inspections and other UVA and Violet (380-420 nm) applications. This third generation of UV LEDs maintains the same micro package size as LUXEON Z UV, but enables a higher power density. LUXEON UV U1 also features a robust design that eliminates materials like silicone over mold, which tends to yellow and crack upon UV exposure, and the elimination of wire bonds that can lead to catastrophic connection failures. “UV LED customers are reliability driven. They tend to run their equipment 24/7 and demand a proven product that will perform as expected for over 20,000 hours. The LUXEON UV U1 is that reliable product,” said Yan Chai, Product Line Director of Lumileds UV LEDs.
