ADVANCED UV FOR LIFE Consortiium and IUVA Joint International Conference
UV LED Technologies & Applications
Commercial relevance of UV LEDs is increasing; since the devices are gaining maturity they become more and more attractive for broad industrial use. Due to their manifold applications, they open up new markets, and innovative products can be developed. At the international conference, the state of the art of UV LED technology, integration of UV LEDs into modules and systems as well as and their application in industry and research are discussed. One focus here is on technically challenging short-wavelength UVC LEDs, which can be used, for example, in water treatment and disinfection.
OUR CONTRIBUTION: Miniaturized Hermetic Reflector Cavity Packaging for UV LEDs
This presentation proposes a novel solution. A hermetic SMD-compatible packaging approach that integrates reflectors into the package to maximize the light extraction. Side emitted and thus wasted light can be recovered by a large percentage. Furthermore it shows, how to avoid costly 3D-structured ceramics by incorporating the reflector into a fused silica window, which is then placed over an already mounted LED chip (flip chip or wire bonded) on a standard flat ceramic. To yield a fully hermetic package this attachment can be done by metal bonding. Design choices of the reflector structures allows us to tailor the radiation patterns of the LEDs. The manufacturing approach allows for miniaturization of the packages as well as further enabling miniature packaging of LED arrays.
We are looking forward to see you in Berlin!
