Lumileds sets the UV LED standard with the industry’s smallest high-power UV LED emitter.


With FlipChip platform technology, LUXEON UV FC Line contains both 1mm2 and 2mm2 die sizes and is the smallest and highest power density (W/cm2) ultraviolet with FlipChip Technology in a Chip Scale Package (CSP) LED that can be reflowed onto a substrate with standard surface mount (SMT) equipment and process. LUXEON UV FC Line LEDs enable tighter beam control and high packing density of LEDs on a chip on board solution and completely eliminate wire bonds in the system. LUXEON UV FC Line is the ideal choice for cost sensitive applications to achieve high irradiance at high current density, maximizing W/$ by taking advantage of the lowest thermal resistance of a CSP device.

  • Ultraviolet wavelength range of 380nm to 420nm for a range of options
  • Micro sized CSP: 1.0mm2 for design flexibility and packing density
  • No wire bonds allows for direct attach and reflow
  • 5-sided emitter with batwing radiation pattern
  • Low thermal resistance for leading system level W/$
  • Maximum drive current of 1A/mm2 delivers superior flux for reduced LED count


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.

  • 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
