IllumInatIon luXeon uV u line Highest power density, superior efficiency, powered by leading Chip Scale Package (CSP) technology At a micro package size compared to other ultraviolet and violet LEDs, LUXEON UV U Line LEDs are SMT devices that can be assembled in tight arrays with spacing of only 200 microns, which enables high power density (W/cm) systems for superior efficiency and design freedom. These products are undomed for precise optical control and include a portfolio of 1mm and 2mm die sizes covering ultraviolet and violet light. The superior power density, excellent robustness of CSP technology and real world efficacy enable leading performance and efficient solution development in a wide variety of UV specialty lighting applications. Features and BeneFIts PrImary aPPlIcatIons Offering ultraviolet in 380-400nm and violet (400420nm) for a range of options Specialty Lighting 2 Small 2.2 to 3.6mm SMT footprint enables highest W/cm power density, Analytical Instrumentation design freedom 2 1A per mm die size maximum drive current allows more power per LED Curing Up to 50%+ efficiency reduces heat output Medical AlN package R as low as 1.8 K/W for better thermal management Security th UV Photoreaction RoHS COMPLIANT DS178 LUXEON UV U Line Product Datasheet 2018 Lumileds Holding B.V.
