Nikkiso starts shipping 30mW deep-UV LEDs

Nikkiso America Inc of San Diego, CA, USA (the US arm of Tokyo-based Nikkiso Co Ltd, which is developing and commercializing deep ultraviolet LEDs) has initiated shipments of what is claimed to be the world's highest-power deep-UV LEDs, featuring three times more optical power output than is commercially available from other sources in the UV-C and UV-B range.

Nikkiso's UV-LED business is introducing the new high-power deep UV-LED product line for the first time in North America in booth #4815 (North Hall) at the SPIE Photonics West 2015 exhibition in San Francisco (10-12 February). The UV-LEDs are designed for applications in biomedical instrumentation and treatment, germicidal purification and sterilization, and industrial curing and printing.

Developed by 2014 Nobel Prize winning professors Akasaki and Amano, the new Nikkiso UV-LED products include single-chip LEDs and multi-chip LED modules. The single-emitter products feature what is claimed to be industry-leading power of 30mW at UV-C and UV-B wavelengths. Utilizing these devices, Nikkiso's new multi-watt module products feature intensities in excess of 100mW/cm2. The devices can be used in stand-alone light sources, or integrated as OEM components into end-customers' final product solutions.

Using proprietary aluminium gallium nitride (AlGaN) technology, Nikkiso notes that its UV-LEDs offer advantages over UV lamps including mercury-free operation, direct on-off modulation and instantaneous analog power control, compact and lightweight form factor, flexible emission wavelength, directional illumination, low voltage and direct current drive. Great demand is therefore expected for deep-UV LEDs in fields such as biomedical instrumentation and dermatology, curing of industrial resins and inks, and air purification and water sterilization.

Nikkiso says that its UV-LED factory in Japan's Ishikawa Prefecture has production technology that enables mass manufacturing on a commercial basis, including new epitaxial equipment, wafer fabrication, and cleanroom facilities. The production facility represents a $22m investment into Nikkiso's UV-LED business, targeted at ensuring a stable supply of deep-UV LED products to the firm's partners (accelerating the development of deep-UV LED applications).
