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.

Features & Benefits

  • Offering ultraviolet in 380-400nm and violet (400–420nm) for a range of options
  • Small 2.2mm² to 3.6mm² SMT footprint enables highest W/cm² power density, design freedom
  • 1A per mm² max drive current allows more power per LED
  • Up to 50%+ efficiency reduces heat output
  • AlN package Rth as low as 1.8 K/W for better thermal management
