Innovations in Optics introduces LumiBright UV Boards for high-power UV LED applications, such as UV curing, 3D printing, maskless lithography, photodynamic therapy, and fluorescence excitation in life science or machine vision.
LumiBright UV Boards offer maximum heat and current spreading to deliver high UV optical power with thermal management and open platform flexibility that provides compact UV LED design solutions.
The Boards utilize chip-on-board LED technology with metallic core PCB substrates that feature a large emitting area using a closely packed array of UV LED chips. Standard center wavelengths include 365 nm, 385 nm, 395 nm, and 405 nm. The 1.1 mm square LED die can be PCB mounted as a single chip or in arrays up to 4 x 4 chips to provide 19.4 mm2 of source area. Each die can be driven to emit near 2 W/mm2; therefore, a 16-die array can supply close to 40Wof UV optical power.
LumiBright UV Boards emit directly into the air with no epoxy or lens encapsulation. Light extraction is maximized providing a Lambertian far-field distribution pattern to support optical design flexibility. The product line offers custom configurations and a small footprint for integration into OEM systems. With a large surface area, liquid light guides can be easily butt-coupled to the LumiBright UV Board for spot-curing applications.
With a low thermal resistance that allows high current density, while maintaining a low junction temperature, LumiBright UV Boards can drive the UV LEDs to the power levels needed for industrial processes. An on-board thermistor permits real-time temperature measurement for either closed-loop control or active monitoring of cooling system operation to optimize an UV LED lifetime, which can exceed 10,000 hours.
Accessories accompanying LumiBright UV Boards include thermal management devices, wire harnesses, and driver-controllers.
