Development of a UV LED illuminator

UV LEDs have achieved performances that now allow to consider disinfection solutions using this technology to replace the discharge sources.To make the most of UV LED sources, it is nevertheless necessary to clearly define the performance objectives expected at the application level (irradiance, uniformity, spectral distribution) and to know how to integrate them appropriately, taking into account the interaction between UV radiation and micro-organisms or particular operating conditions of UV LEDs. The main objective was to develop a UV LED illuminator able to kills certain type of bacteries.

Performed services

  • Definition of application requirements (energy levels, uniformity, cost)
  • Component scouting LED UV (Viosys, Vishay, LG, Luminous, Rayvio…) and selection of appropriate LEDs.
  • Design of the illuminator board (type and # UVA and UVC LEDs, electrical and thermal functional points , PCB type of PCB, driver…).
  • Prototype realization.
  • Photobiological risk assessment.
