UV LED Irradiation Systems

We develop UV LED based irradiation systems - adapted and ready for use for diverse applications. In particular, our own UV-LEDs are used, supplemented where necessary by LEDs from commercial suppliers. So far, we have implemented irradiation systems that are used for plant growth, water and surface disinfection, and skin-tolerant UV antisepsis. Further information can be found at our prototypes.

The advantages of UV LEDs at a glance

  • small, compact and robust
  • can be operated at low voltages (mobile applications)
  • can be switched quickly
  • do not contain toxic substances

Thanks to these properties, systems with UV LEDs are already superior in many respects to those with conventional UV radiation sources such as mercury-based gas discharge lamps, although their efficiencies are currently still lower.

Complete value chain in-house

  • epitaxial deposition of the semiconductor heterostructures on different MOVPE machines
  • chip technology in the process line of the FBH clean room
  • mounting of the LED chips in suitable packages with special lens covers
  • design of the overall system (incl. simulation of radiation characteristics and thermal management)
  • fabrication of the electronic and mechanical components including assembly and control software
  • characterization and qualification of the overall system (e.g. radiation characteristics, degradation behavior and definition of ideal operating conditions)
