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

Patent number: 11860386Abstract: An apparatus and method for displaying an image are disclosed. The apparatus includes microLED unit cells including sets of microLEDs each emitting light and at least one lens to control an emission angle and emission profile of the light emitted by the microLED unit cells. A display controller controls an intensity distribution of the microLED unit cells in accordance with first and second video data signals such that a first portion of the emitted light is emitted at a first emission angle with a first emission profile at a first observation angle relative to a display and a second portion of the emitted light is emitted at a second emission angle with a second emission profile at a second observation angle relative to the display. The first and second light portions form unrelated images.Type: GrantFiled: December 21, 2020Date of Patent: January 2, 2024Assignee: Lumileds LLCInventors: Johannes Willem Herman Sillevis Smitt, Charles André Schrama, Erno Fancsali

Publication number: 20230410726Abstract: A vehicular display that contains a sparse array of light-emitting diodes (LEDs), system, and method of fabrication are disclosed. The vehicular display includes at least one tile disposed in a vehicle to provide a display of internal and external information. Each tile has a transparent flexible substrate, a sparse array of LEDs disposed on the transparent flexible substrate, a rigid substrate adhered to the transparent flexible substrate via an adhesive layer in which the sparse array of LEDs is encapsulated, and a driver disposed on an edge of the tile and configured to drive the LEDs. The LEDs are sparse enough to enable information to be displayed through a vehicle window while still enabling a viewer to see through the window.Type: ApplicationFiled: June 14, 2023Publication date: December 21, 2023Inventors: Brendan Jude Moran, Johannes Willem Herman Sillevis Smitt, Dirk P.J.

Publication number: 20230408820Abstract: A virtual reality (VR) headset, system, and method of fabrication are disclosed. The VR headset includes a frame, a transparent display that includes an array of light-emitting diodes (LEDs), and a darkening layer having a controllable opacity, and a processor controlling the display and darkening layer. A proximity sensor detects a potential collision, and the opacity is changed from opaque to transparent in response to detection of the potential collision. The opacity is changed in response to activation of a virtual user input or predetermined eye movement.Type: ApplicationFiled: June 14, 2023Publication date: December 21, 2023Inventors: Mark James Holmes, 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
