Publication number: 20190088840Abstract: A method to make light-emitting diode (LED) units include arranging LEDs in a pattern, forming an optically transparent spacer layer over the LEDs, forming an optically reflective layer over the LEDs, and singulating the LEDs into LED units. The method may further include, after forming the optically transparent spacer layer and before singulating the LEDs, forming a secondary light-emitting layer that conforms to the LEDs, cutting the LEDs to form LED groups having a same arrangement, spacing the LED groups on a support, and forming the optically reflective layer in spaces between the LED groups.Type: ApplicationFiled: September 2, 2016Publication date: March 21, 2019Applicant: Lumileds Holding B.V.Inventors: Frederic S.

Patent number: 10217917Abstract: The device according to the invention comprises a nanostructured LED with a first group of nanowires protruding from a first area of a substrate and a contacting means in a second area of the substrate. Each nanowire of the first group of nanowires comprises a p-i-n-junction and a top portion of each nanowire or at least one selection of nanowires is covered with a light-reflecting contact layer. The contacting means of the second area is in electrical contact with the bottom of the nanowires, the light-reflecting contact layer being in electrical contact with the contacting means of the second area via the p-i-n-junction. Thus when a voltage is applied between the contacting means of the second area and the light-reflecting contact layer, light is generated within the nanowire. On top of the light-reflecting contact layer, a first group of contact pads for flip-chip bonding can be provided, distributed and separated to equalize the voltage across the layer to reduce the average serial resistance.Type: GrantFiled: March 10, 2017Date of Patent: February 26, 2019Assignee: GLO ABInventors: Steven Konsek, Jonas Ohlsson, Yourii Martynov, Peter Jesper Hanberg
