Patent number: 9786811Abstract: The present disclosure is directed to LED components, and systems using such components, having a light emission profile that may be controlled independently of the lens shape by varying the position and/or orientation of LED chips with respect to one or both of an overlying lens and the surface of the component. For example, the optical centers of the LED emitting surface and the lens, which are normally aligned, may be offset from each other to generate a controlled and predictable emission profile. The LED chips may be positioned to provide a peak emission shifted from a perpendicular centerline of the lens base. The use of offset emitters allows for LED components with shifted or tilted emission patterns, without causing output at high angles of the components. This is beneficial as it allows a lighting system to have tilted emission from the LED component and primary optics.Type: GrantFiled: March 15, 2013Date of Patent: October 10, 2017Assignee: CREE, INC.Inventors: Fabian Rol, Eric Tarsa, Bernd Keller, Theodore D.

Patent number: 9450163Abstract: An SMD includes a substrate and one or more electrical contacts on a first surface of the substrate. Each one of the electrical contacts are configured to couple to a corresponding electrical contact located on a surface of a carrier, and are located within a concentric area of the first surface that is less than about 50% of a total area of the first surface. By providing the electrical contacts within the concentric area, the mechanical stress experienced by the electrical contacts can be significantly reduced when compared to conventional SMDs including electrical contacts on the outer edges thereof. Accordingly, the failure rate of the SMD due to separation of one or more of the electrical contacts from the carrier may be reduced.Type: GrantFiled: May 26, 2015Date of Patent: September 20, 2016Assignee: Cree, Inc.Inventors: Theodore D.
