    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.

    Abstract: An LED light fixture including a frame defining a forward open region and a rearward region with a rearmost portion adapted for securement to a support member. An LED assembly is secured with respect to the frame and positioned within the open forward region with open spaces remaining therebetween. The LED assembly includes an LED illuminator secured with respect to the LED-supporting region of a heat sink with an LED-supporting region and heat-dissipating surfaces extending therefrom. Another aspect of the invention is a non-metallic frame defining a forward open region and having a rearward region having a rearmost portion adapted for securement to a support member. An LED assembly is secured with respect to the frame and positioned within the open forward region with open spaces remaining therebetween.

    Abstract: A modular troffer-style fixture that is well-suited for use with solid state light sources, such as LEDs, to provide a surface ambient light (SAL). The fixture comprises two structural components: a housing subassembly and a lighting subassembly. These two subassemblies may be removably attached to operate as a singular fixture. Many different lighting subassemblies may be compatible with a single housing subassembly and vice versa. The housing subassembly comprises a body that is mountable to an external structure. The lighting subassembly comprises the light sources and optical elements that tailor the light to achieve a particular profile. Electronics necessary to power and control the light sources may be disposed in the housing subassembly, the lighting subassembly, or both. Various mount mechanisms may be used to attach the fixture to a surface such as a ceiling or a wall. Multiple fixtures can be connected serially to provide an extended continuous fixture.

    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.
