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: Light fixtures having light bar elements therein. In order to mimic the size and appearance of fluorescent bulbs in existing troffer-style and surface-mount fixtures, LEDs are may be arranged on light bars with integrated lenses to both diffuse the light and shape the output beam. One or more LEDs can be mounted, sometimes in clusters, along the length of a base of the light bar which can then be inserted into a fixture. An elongated lens is mounted to the base over the LEDs so that light emitted from the LEDs interacts with the lens before it escapes the fixture. These elongated lenses may be extruded from a diffusive material, for example, and can be shaped in various ways. For example, the lenses may be shaped to disperse more light to the sides, i.e., in a direction away from a normal axis that is perpendicular to the base.

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: 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.
