Abstract: Solid state light emitting devices include one or more light affecting elements (e.g., of one or more light-transmissive, light-absorptive, light-reflective, and/or lumiphoric materials) formed on, over, or around at least one solid state light emitter, with the light affecting elements including multiple fused elements embodying plurality of dots, rods, or layers such as may be formed by three-dimensional (3D) printing. At least one electrically conductive path in electrical communication with a solid state light emitter may be formed by selective material deposition such as 3D printing. Light affecting elements may be individually tailored to individual solid state light emitters, such as to yield different optical distributions for interactions between each specific emitter and its corresponding light affecting element.

Abstract: A direct troffer-style fixture for solid state light sources and pan structures for use in these fixtures. The fixture comprises a door frame assembly that is attached to the pan. The pan housing is defined by a base and two angled side walls. End caps are attached to the side walls. End reflectors extend at an angle away from the end caps and attach to the base. The end caps, the end reflectors, and the base define compartments at both ends of the housing in which components can be housed. A light board is attached to the base using alignment holes in the base and cutout portions of the end reflectors. The multifunctional end reflectors retain elements within the compartments, provide added structural stability to the pan, aid in aligning a light board, and they reflect light that impinges on them toward the open end of the fixture.

Abstract: A wire-bond free semiconductor device with two electrodes both of which are accessible from the bottom side of the device. The device is fabricated with two electrodes that are electrically connected to the oppositely doped epitaxial layers, each of these electrodes having leads with bottom-side access points. This structure allows the device to be biased with an external voltage/current source, obviating the need for wire-bonds or other such connection mechanisms that must be formed at the packaging level. Thus, features that are traditionally added to the device at the packaging level (e.g., phosphor layers or encapsulants) may be included in the wafer level fabrication process. Additionally, the bottom-side electrodes are thick enough to provide primary structural support to the device, eliminating the need to leave the growth substrate as part of the finished device.

The heat-conductive structure having an LED-supporting region and heat-dissipating surfaces extending away therefrom. The at least one LED light source is thermally coupled to the LED-supporting region. The heat-conductive structure defines venting apertures bordering the at least one LED light source to facilitate ambient fluid flow to and from the heat-dissipating surfaces. In some embodiments, the LED light fixture includes a protrusion extending into a corresponding one of the venting apertures and oriented to direct air flow. In certain embodiments, the heat-conductive structure defines a plurality of venting apertures adjacent the at least one LED light source, the heat-dissipating surfaces include fins increasing in height at positions adjacent to the at least one of the venting apertures.

Abstract: An LED light fixture including a housing, a heat sink secured with respect to the housing and an LED illuminator secured with respect to the heat sink. The heat sink includes central and peripheral portions. The central portion has an LED-supporting surface and forward, rearward and lateral sides, the LED illuminator being at the LED-supporting surface. The peripheral portion extends laterally from the lateral sides. The central portion of the heat sink has downwardly-extending shield members at the lateral sides thereof configured and dimensioned to block illumination in a direction opposite the LED illuminator. In embodiments where the optical member is configured for directing emitter light predominantly toward the forward side, the central heat-sink portion has a downwardly-extending shield member at the rearward side thereof configured and dimensioned to block rearward illumination.
