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.

Abstract: Frame and lens upgrade kits for lighting fixtures. A frame bracket defines the frame area, which can be rectangular, for example. A lens frame fits just inside the frame bracket with the lens frame being releasably attached thereto. The frame bracket can be constructed from collapsible frame bracket subassemblies. For example, a rectangular frame bracket may be assembled from first and second collapsible frame bracket subassemblies that fan out and lock together to create a rigid frame bracket. The subassemblies each comprise elongated side and edge brackets that are fastened together such that they can pivot about one another. In some embodiments, one side of the lens frame is attached to a corresponding side of the frame bracket with a rotatable clip that allows the lens frame to swing such that its other side can attach to the bracket frame with an attachment latch, which can be magnetic, for example.

Abstract: A solid state lighting device includes multiple solid state light emitters and a control circuit configured to adjust aggregated emissions to produce a mixture of light having an adjustable color point together with high luminous efficacy, wherein at least one color point is on or near the white body line WBL (line of minimum tint). Adjustment of color point may provide substantially constant 1931 CIE x-values; substantially constant 1931 CIE y-values, or substantially constant distance relative to the blackbody locus (e.g., with variation in CCT of at least 100K for the color points). An adjustable color point may be arranged to transition between one point near the BBL and another point on or near the WBL. An adjustable color point may provide a first color point on or near the WBL and another point having different CCT and luminous flux. Emitters selected solely from discrete bins or subregions of a CIE diagram may be used in combination to yield a point on or near the WBL.

Abstract: Retrofit systems and methods are disclosed for lighting installations, and in particular, to retrofit systems and methods used to retrofit troffer-style lighting installations with LED light sources. Retrofit systems can be used with different light fixtures, but those described are particularly adapted for use with troffer-style fixtures. These retrofit systems can provide the same amount of light as traditional light fixtures already do, for example 1600-4000 lumens or more. The retrofit systems can be used with many different light sources but are particularly well-suited for use with solid state light sources or light engines, such as those utilizing LEDs. Some embodiments of the present invention comprise a mechanical mounting system for installing an LED light engine within an existing lighting system housing or pan, such as a troffer pan, without penetrating the ceiling plenum.
