UV Radiation with LEDs
Nichia: market and technology leader for LEDs
Japanese manufacturer Nichia is an undisputed pioneer in the UV light range. The company is responsible for its pioneering work in the discovery of the white LED light and for setting new standards in the LED market with research and development of UV LEDs.
Nichia has conducted research in the low wavelength range more than 15 years to emit even more energy-intensive light radiation with LED technology. The unique production process is subject to strict quality control, from the wafer production to the final production inspection in Japan.
Lumitronix shares this quality requirement as an official distributor and is a long-term partner and problem-solver for the industry. In addition to comprehensive advice, we offer our customers customised development and production in-house at our location in Hechingen – everything provided from a single source and Made in Germany.
UV A radiation: Wide application spectrum
The long-wave UV A light triggers various photochemical processes. The radiation of UV A LEDs penetrates glass and transparent plastics. UV A light is used in numerous industrial areas.
- Hardening of paints, lacquer and adhesives
- Material testing using fluorescent testing substances
- Identification of contamination (clean room)
- Disinfection of surfaces or air
- Light therapy (e.g. for skin ailments)
- Hardening (dental applications)
- Bank note inspection
- Document inspection
- Recognition of fingerprints
- Detection of bacteria
- Networking of DNA/RNA
- Excitation for fluorescence (fluorescence microscope)
High-energy radiation
The medium-wave UV B rays are responsible for the formation of pre-vitamin D in the human body and are predominantly used for light therapy.
UV C rays are short-wave and more energy-intense than UV A and UV B rays. They have a powerful germicidal effect in the range of 260nm. For this reason, they are often used in air and water preparation processes.
- Disinfection (e.g. air or water preparation)
- Odour neutralisation
- Light therapy
- Sterilisation (e.g. in water preparation)
- Turbidity (e.g. in glasses or optical components)
