Abstract:
A direct troffer-style fixture for solid state light sources for use in these fixtures. Embodiments of the present invention provide a direct troffer-style fixture that is particularly well-suited for retrofit structures. The fixture comprises a retrofit troffer assembly that is removably attached within a T grid or pan structure. The retrofit fixture can be installed in two pieces: a first including a lens structure, a back reflector and 2 end reflectors; and the second component including a second portion of the back reflector. An interior space created by the lens structure houses light emitters and in some embodiments, a light engine and/or additional electronics. One or both of the end reflectors may be movable, slidable and/or rotatable, to accommodate installation. The back reflector covers most of the interior surfaces of the troffer fixture to direct more light out of the fixture.
Abstract:
An edge lit fixture. A housing provides the basic shape and structure of the fixture. The housing is constructed from discrete segments including lens frames, side frames, and end frames, which can be used in many different combinations to create the desired fixture. The assembled housing defines an open central area. One or more light panels are arranged around the perimeter of the housing such that at least some of the light is emitted toward the central area. The open central area of the housing allows for existing materials, such as a ceiling tile, for example, to function as a back surface of the fixture.
Abstract:
An edge lit fixture. A light engine comprises a compartment and at least one elongated lens that are attachable to a mount plate. The mount plate, an exterior surface of the compartment, and the lens define an internal optical cavity. A light strip is mounted to the mount plate within the optical cavity. One or more legs can be used to attach the fixture to an external surface, such as a ceiling T-grid. The light engine can be used with legs of varying size such that it can fit within ceiling openings having different dimensions. The assembled fixture defines an open area. One or more light engines are arranged around or through the open area such that light is emitted into the open area. The open area of the fixture allows for existing materials, such as a ceiling tile, for example, to function as a back side reflector panel.
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:
Solid state downlights include a fixture that has a solid state lighting housing, a plurality of light emitting diodes within the solid state lighting housing and a junction box, and at least one mounting structure that is configured to releasably attach the fixture directly to a ceiling to mount the fixture within an opening in the ceiling.
Abstract:
Systems, devices and methods for controlling one or more lights are disclosed. In some aspects, systems for controlling one or more lights can include an interface and a remote sensing device that is separate from and is in electrical communication with the interface. The remote sensing device can additionally include at least one sensor, for example an ambient light sensor. Each of the remote sensing device and the interface can be configured to attach to support structures via retaining features. In one aspect, the remote sensing device can include a first and a second retaining member that rotatably thread onto a main body of the sensing device and adjust according to the thickness and structure of the support structure. In another aspect, the interface can include a retention feature utilizing flexible tabs with integrated detents to accommodate variable sizes of openings of the support structure.
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 upward illumination. 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.
Abstract:
An LED light fixture including a housing and an LED assembly secured with respect to the housing. The LED assembly includes a heat sink and an LED illuminator secured with respect to an LED-supporting region of the heat sink with heat-dissipating surfaces extending therefrom. The heat sink having front, rear and lateral sides and being open to ambient-fluid flow to and from the heat-dissipating surfaces along each of the sides.
