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/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.
