Patent number: 11585965Abstract: Described herein is a system and method for tuning light scatter in an optically functional porous layer of an LED. The layer comprises a non-light absorbing material structure having a plurality of sub-micron pores and a polymer matrix. The non-light absorbing material forms either a plurality of micron-sized porous particles dispersed throughout the layer or a mesh slab, wherein a plurality of sub-micron pores is located within each micron-sized porous particle or forms an interconnected network of sub-micron pores within the mesh slab, respectively. A polymer matrix, such as a high refractive index silicone fills the plurality of sub-micron pores creating an interface between the materials. Refractive index differences between the materials allow for light scatter to occur at the interface of the materials. Light scatter can also be decreased as a function of temperature, creating a system for tuning light scatter in both an off state and on state of an LED.Type: GrantFiled: August 11, 2020Date of Patent: February 21, 2023Assignee: Lumileds LLCInventors: Marcel Rene Bohmer, Jacobus Johannes Franciscus Gerardus Heuts, Daniel Estrada, Kentaro Shimizu

Patent number: 10871268Abstract: An LED lighting unit comprising a support structure (14), an LED-based light emitting structure (10) mounted within the support structure and an optical beam shaping arrangement (50, 52) over the top of the support structure. The optical beam shaping arrangement comprises an optically transparent and thermally stable material, and the support structure supports the microstructured layer at a small height above the LED-based light emitting structure. This height may for example be less than 0.5 mm. The optical beam shaping arrangement enables a compact and low height lighting unit to be mounted on a carrier by reflow soldering without damaging the optical beam-shaping component.Type: GrantFiled: June 26, 2015Date of Patent: December 22, 2020Inventors: Hendrik Johannes Boudewijn Jagt, Floris Maria Hermansz Crompvoets, Wouter Dekkers, Fritz Helmut Zahn, Olexandr Valentynovych Vdovin, Jacobus Johannes Franciscus Gerardus Heuts, Maria Johanna Helena Jochem, Christian Kleijnen
