Luminus shipping 382-392nm UV LED for spot-curing, 3D prototyping and fiber-coupling applications

Luminus Devices Inc of Billerica, MA, USA, which manufactures PhlatLight (photonic lattice) LEDs for illumination applications, says that production models of its largest ultraviolet (UV) LED device, the CBT-120-UV-C11, are now shipping in the 382-392nm wavelength range.

The firm says that applying its photonic lattice technology to UV wavelengths opens the single-chip 12mm2 device platform up to many new applications. “We have already seen early customers in the fields of rapid prototyping, ink and adhesives curing, scientific & medical instrumentation plus purification benefit from engineering samples of this powerful new monolithic device,” says Michael Lim, director of global industrial and new business. “By making this device available more broadly, we are excited to see how the highest power-density UV LED device will benefit additional customers and industries,” he adds.

“The power density delivered by the CBT-120-UV, along with its capability for optimized coupling to high-performance DLP [Digital Light Processing] micro-mirror systems, made this LED ideal for us,” comments Roland Hoefling, president of optical metrology and scanning firm Vialux GmbH of Chemnitz, Germany. “We have implemented the Luminus UV light source in our LED-OM DLP Discovery 4100 module that is used in direct imaging maskless lithography, rapid-prototyping and CtcP printing equipment,” he adds. “The size of this device and the capability of Luminus’ package has enabled us to develop advanced technology solutions for our customers and displace UV mercury-vapor lamps due to its power, longevity and efficiency,” Hoefling continues.

Additionally, engineering samples of this chip in 375nm and 405nm wavelengths are available on the same high-performance platform. “Luminus’ approach to innovation enables new and emerging technologies to be rapidly incorporated into our devices,” says Lim. “Luminus’ successful implementation of their ‘Big Chip’ LED technology in the UV space will be complemented by the development of additional UV die sizes, wavelengths including 395nm, as well as work on different form factors,” he adds. “Our technology lets us offer UV integrators a monolithic, easy-to-integrate light source that is RoHS compliant, environmentally friendly and more efficient, with a median 12,000 hour lifetime.”

The devices are on active demonstration display in booth 508 at the Rad Tech UV & EB 2012 tradeshow in Chicago (30 April – 2 May). Luminus’ UV LEDs can be purchased through Avnet in North America, EBV in Europe, and Mouser globally.
