Patent number: 10901142Abstract: Interlocking light emitting diode (“LED”) light guide tiles are disclosed. The tiles have interlocking edge features that provide physical interlock fitting between tiles and present a continuous appearance, both in an “on,” where LEDs are powered on and emitting light state and an “off” state, where LEDs are powered off and not emitting light. The LED light guide tiles interface with LEDs (housed in or embodied as integrated circuit LED packages) to output light through the surfaces of the light guide. The interlocking edge features of the light guide tiles are shaped to obscure or block an image of the LED packages from being seen by observers looking at the light guide tiles. Light guide tile assemblies or installations can be easily formed out of interchangeable tiles with little or no requirement for relative directional alignment of the tiles.Type: GrantFiled: May 6, 2020Date of Patent: January 26, 2021Assignee: Lumileds LLCInventors: Jeroen Den Breejen, Frederic Stephane Diana

Patent number: 10890709Abstract: In one embodiment, an overhead street light (a luminaire) is formed that has an asymmetric light intensity distribution, where the peak intensity is greatest along the direction of the street, lower directly across the street, and much lower on the house side of the street. Around the edge of a circular transparent light guide are white light LEDs that inject light into the light guide. To help control the asymmetry of the light intensity distribution, sawtooth-shaped grooves are formed in the light guide surface opposite to the light-emission surface and parallel to the street. Gaussian diffusers are used to partially diffuse the light. By proper selection of the grooves, the Gaussian diffuser, and the relative amounts of light emitted by LED segments around the light guide, the desired asymmetrical light intensity distribution is achieved while a direct view of the light exit surface appears as a uniform light.Type: GrantFiled: August 8, 2019Date of Patent: January 12, 2021Assignee: Lumileds LLCInventors: Frederic S. Diana, Gregory Guth, Jeroen Den Breejen, Iain Black

Patent number: 10868076Abstract: A light engine is disclosed in which the light engine contains a core having an opening extending completely therethrough and independently addressable LED segments. The opening defines an inner surface of the core. Each segment has LEDs and is attached to a flexible PCB. The PCB has a flexible body attached to one of an inner or outer surface of the core and to which the segments are mounted, and flexible legs extending from the body, along the core, and traverse and adjacent to the other of the inner or outer surface. A light guide plate (LGP) receives and guides light from the segments so that the light exits to provide illumination. The segments emit light in all directions of a plane created by the LGP. A reflector opposes and covers a top surface of the LGP and the segments and reflects light from the LGP back into the LGP.Type: GrantFiled: February 10, 2020Date of Patent: December 15, 2020Assignee: Lumileds LLCInventors: Frederic Stephane Diana, Yifeng Qiu, Michael Wasilko, Nazila Soleimani, Jeroen Den Breejen, Alan Andrew McReynolds, Gregory Donald Guth
