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/cm²) systems for superior efficiency and design freedom. These
products are undomed for precise optical control and include a portfolio of
1mm² and 2mm² 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.
