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.
To develop a UV LED illuminator able to kills certain type of bacteries.
> Definition of aplication requirements (energy levels, uniformity, cost)
> Component scouting LED UV (Viosys, Vishay, LG, Luminous, Rayvio…) and selection of
> Design of the illuminator board (type and # UVA et UVC LEDs, electrical and thermal
functional points , PCB type de PCB, driver…).
> Prototype realization.
> Photobiological risk assessment.
