Frequently Asked Questions

1. What are the benefits and drawbacks of using UV-LEDs?

The benefits of UV-LEDs over UV lamps are numerous, and include mercury-free operation, direct modulation and rapid on/off cycling, customized emission pattern and emission spectrum, ultra-compact size and form factor, low maintenance cost, low temperature operation, and minimal “fouling” (hardening of materials onto the light source during operation). Historically, UV-LEDs have not been commercially available with sufficient efficiency, reliability, or cost. Nikkiso’s innovations have addressed these challenges and made this technology commercially accessible on a global scale enabling our customers to benefit from UV-LEDs today. Learn more about our technology.

2. Can I replace my UV laser or lamp with UV-LEDs in my bio-instrument?

Yes, Nikkiso UV-LEDs are typically more cost effective than lasers while providing more wavelength flexibility. Moreover, Nikkiso UV-LEDs are more compact and reliable than lamps, and are mercury free. Please contact us, and we can help you identify specific UV-LED source solutions for your application.

3. Can UV-LEDs kill bacteria and viruses?

Yes, in application testing, Nikkiso UV-LEDs have proven to deliver log 4 extinction with UV-LED irradiation in a wide variety of viruses and bacteria such as e-coli, staphylococcus, bacillus, salmonella, aspergillus, and even norovirus.

4. I am a printer currently using UV lamps, and I want to use UVC LEDs, but do not have knowledge in this field. Do I need to know how to integrate LEDs in my specific application?

Detailed integration understanding is not needed.  Nikkiso’s UV-LED solutions team will help you step by step in integrating UV-LEDs into your applications. Nikkiso offers off-the-shelf integrated solutions, and can develop application-specific, customized, multi-chip modules with the required spectral and spatial emission to meet your needs.

5. How are Nikkiso LED chips different than other LED chips?

Nikkiso UV-LED technology was developed by optoelectronics pioneers Professors Akasaki and Amano, recipients of the 2014 Nobel Prize in physics. The Nikkiso UV-LED technology approach is unique because it delivers a combination of industry-leading performance and reliability, while utilizing cost-effective, high-volume manufacturing materials and methods. The Nikkiso UV-LED performance and reliability advantage is achieved with proprietary semiconductor chip innovation, including novel epitaxial growth and device processing customized for the deep ultra-violet regime. These high-performance chip designs were specifically developed to be manufactured with high-volume, low-cost consumer LED lighting infrastructure, leveraging industry-proven fabrication tools and large scale sapphire substrates. Nikkiso UV-LED technology is protected by extensive intellectual property, including numerous patents and trade secrets.

Alternative approaches to UV-LEDs suffer two primary issues: either they are utilizing low cost approaches but have performance, efficiency, and reliability issues, or they utilize expensive and exotic materials which are not manufacturable or reliable.
