Luminus Devices, Inc. recently announced at SPIE's Photonics West trade show that production units of a new high-powered UV Big Chip LEDTM in Luminus' popular CBT-90 form factor are now available for immediate delivery.
By providing a high-performance form factor at 405 nm, the CBT-90-UV LEDs will help accelerate the conversion to solid-state UV light sources in industrial markets. The CBT-90-UV LEDs contain a single monolithic 9mm2 die that emits directly into air. At 13.5A forward current, these LEDs produce a NIST-traceable power output ranging from 7 W to 9.1 W at 405 nm peak-wavelength, making them ideal for UV life science, machine vision and curing applications.
The CBT-90-UV LED provides all of the traditional advantages of Luminus' Big Chip LED technology, including improved thermal power density and simpler support system architecture, along with delivering greater wall-plug efficiency than traditional sized LED dies and arrays.
Designed it to replace traditional UV mercury vapor lamps, the CBT-90-UV's features provide new high power LED solutions that also deliver longer lifetimes, greater energy efficiency, the reduction of harmful emissions, and the elimination of environmental disposal issues.
