Luxeon Doubles Performance of chip scale UV LED
Lumileds has introduced a new Luxeon UV LED, which it says delivers twice the irradiance power of its previous generation product in a miniature 2.2 mm2 SMD chip scale package.
According to the company, the Luxeon UV U1, the third generation of LEDs for UV curing, counterfeit detection, analytical instrumentation, inspections and other 380-420 nm applications, maintains the same micro package size as Luxeon Z UV, but enables five times greater power density.
The new LED is also said to feature 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.
The UV U1 is nominally tested at 500mA but can be driven at up to 1A to achieve higher irradiances. For the application of UV curing at 395 nm, Luxeon UV U1 achieves 700 mW at 500mA and >1300 mW at 1A under 25degC.
The footprint is a drop-in replacement for the Luxeon Z UV.
