General Illumination LUXEON FlipChip UV Chip-scale package for maximum design flexibility in UV applications LUXEON FlipChip UV is the smallest and highest power density (W/cm2) ultraviolet with FlipChip Technology in a chip-scale package LED can be reflowed onto a substrate with a standard surface mount (SMT) equipment and process. LUXEON FlipChip UV LED enables tighter beam control and high packing density of LEDs on a chip-on-board solution and completely eliminates wire bonds in the system. LUXEON FlipChip UV is the ideal choice for cost sensitive applications to achieve high irradiance at high current density, maximizing W/$ by taking the advantage of lowest thermal resistance of a chip-scale package device. Primary Applications Ultraviolet wavelength range of 380–410nm for a range of options Specialty Lighting Micro sized CSP: 1.0mm2 package for design flexibility and packing density No wire bonds allows for direct attach and reflow 5-sided emitter with batwing radiation pattern enables wide viewing angles Low thermal resistance for leading system level lm/$ Maximum drive current of 1A for delivers superior lumens for reduced LED count DS137 LUXEON FlipChip UV Product Datasheet ©2015 Lumileds Holding B.V.
