Patent number: 11946621Abstract: An illumination system can produce a dynamically variable illumination pattern. The illumination system can include a light guide. The illumination system can include projection optics, which can contribute to the illumination pattern at relatively low beam angles (i.e., beam angles formed with respect to a surface normal of the light guide). The projection optics can include individually addressable light-producing elements that can direct light through one or more focusing elements. A controller can control which of the light-producing elements are electrically powered and can therefore control the illumination pattern contribution from the projection optics. The illumination system can also include scattering optics, which can contribute to the illumination pattern at relatively high beam angles. The scattering optics can direct light out of the light guide over a relatively large surface area, which can help reduce glare when the light guide is viewed directly.Type: GrantFiled: April 27, 2023Date of Patent: April 2, 2024Assignee: Lumileds LLCInventors: Wouter Soer, Johannes Willem Herman Sillevis Smitt

Publication number: 20230411572Abstract: A light source can include a transparent flexible substrate. A sparse array of light-emitting diodes (LEDs) can be disposed on the transparent flexible substrate. A rigid substrate can be adhered to the transparent flexible substrate such that the sparse array of LEDs is located between the rigid substrate and the transparent flexible substrate. The rigid substrate can be adhered to the transparent flexible substrate with an adhesive layer. The sparse array of LEDs can be encapsulated in an adhesive of the adhesive layer. The adhesive can have a refractive index that is between a refractive index of the transparent flexible substrate and a refractive index of the rigid substrate, inclusive. The sparse array of LEDs can have a light-emitting area that is less than or equal to a specified fraction of a surface area of the sparse array, such as 5 percent or 1 percent.Type: ApplicationFiled: June 6, 2023Publication date: December 21, 2023Inventors: Wouter Soer, Grigoriy Basin, Brendan Jude Moran, Johannes Willem Herman Sillevis Smitt

Publication number: 20230411579Abstract: Display devices comprise an optionally transparent display area that extends to one or more physical boundaries (edges) of the device. The display area may be located on a front surface of the display device, and the physical boundaries of the device to which the display area extends may be formed by physical sides of the device that intersect with the front surface to define part of a perimeter of the front surface. The display area may comprise a microLED array that extends with the display area to edges of the device. Power and/or control electronics for the display device may be located adjacent the display area but away from the edges of the display device to which the display area extends. Two or more such display devices can be arranged (i.e., tiled) with their display areas adjacent, in contact, and facing the same direction to form an extended continuous microLED display area spanning the display areas of the two or more display devices.Type: ApplicationFiled: June 9, 2023Publication date: December 21, 2023Applicant: Lumileds LLCInventors: Brendan Jude MORAN, Wouter SOER, Grigoriy BASIN, Johannes Willem Herman Sillevis Smitt

Patent number: 11805584Abstract: Techniques and devices are provided for sensing image data from a scene and activating primary light sources based on information sensed from the scene. Subsets of a plurality of primary light sources may be activated to emit sensing spectrum of light onto a scene. Combined image data may be sensed from the scene while the subsets of the plurality of primary light sources are activated. Reflectance information for the scene may be determined based on the combined image data and combined sensing spectra. Spectrum optimization criteria for the primary light sources may be determined based on the reference information and a desired output parameter provided by a user or determined by a controller. The plurality of primary light sources may be activated to emit a lighting spectrum based on the spectrum optimization criteria.Type: GrantFiled: June 22, 2022Date of Patent: October 31, 2023Assignee: Lumileds LLCInventors: Wouter Soer, Willem Sillevis-Smitt

Publication number: 20230343908Abstract: A light-emitting apparatus includes light-emitting and primary optics arrays. The light-emitting array includes multiple light-emitting pixel elements, each emitting at one of one or more output wavelengths. The primary optics array includes multiple metastructured primary optical elements, each receiving output light from a corresponding pixel element and redirecting that light to form a portion of array output light. Different primary optical elements receive pixel output light from different corresponding pixel elements. The primary optical elements differ from one another with respect to structural arrangement of their corresponding metastructures. Those different arrangements result in differing collimation, propagation directions, or angular radiation distributions of the corresponding portions of array output light emitted by different pixel elements of the light-emitting array.Type: ApplicationFiled: June 15, 2023Publication date: October 26, 2023Applicant: LUMILEDS LLCInventors: Wouter SOER, Franklin CHIANG, Oleg Borisovich SHCHEKIN
