Lumileds recently announced the LUXEON UV U1 LED for use in a variety of UV applications, including UV curing, counterfeit detection, analytical instrumentation, inspections and other UVA and Violet (380–420 nm). Featuring the same micro package size as LUXEON Z UV, the new version enables a higher power density.
The LUXEON UV U1 LED is nominally tested at 500 mA, but it can be driven at up to 1 A to achieve higher irradiances. For the application of UV curing at 395 nm, LUXEON UV U1 achieves 700 mW at 500 mA and greater than 1300 mW at 1 A under 25°C. Compared to the 3.5 × 3.5 mm2 package size of most UV LEDs, LUXEON UV U1’s unique micro package size delivers superior packing density as well as greater than 5× higher power density. The LUXEON UV U1’s footprint is a drop-in replacement for the LUXEON Z UV, while providing twice the typical radiometric power as its predecessor at 380–390 nm.
