Patent number: 11411148Abstract: Solid-state lighting devices including light-emitting diodes (LEDs) and more particularly packaged LEDs with light-altering materials are disclosed. A light-altering material is provided in particular configurations within an LED package to redirect light from an LED chip within the LED package and contribute to a desired emission pattern of the LED package. The light-altering material may also block light from the LED chip from escaping in a non-desirable direction, such as large or wide angle emissions. The light-altering material may be arranged on a lumiphoric material adjacent to the LED chip in various configurations. The LED package may include an encapsulant on the light-altering material and the lumiphoric material.Type: GrantFiled: September 10, 2020Date of Patent: August 9, 2022Assignee: CreeLED, Inc.Inventors: Kyle Damborsky, Derek Miller, Jack Vu, Peter Scott Andrews, Jasper Cabalu, Colin Blakely, Jesse Reiherzer

Patent number: 8742654Abstract: A light emitting device includes an LED and a layer of luminophoric particles, such as phosphor, that are non-homogeneous in size as a function of distance away from the LED. For example, a first layer of relatively large size phosphor particles may be provided between a second layer of relatively small size phosphor particles and the LED. The large particles can provide high brightness and the small particles can reduce angular color temperature variation in emitted light.Type: GrantFiled: February 25, 2011Date of Patent: June 3, 2014Assignee: Cree, Inc.Inventors: Jasper Cabalu, Michael John Bergmann
