    Abstract: A light fixture with a textured reflector surface is disclosed. Embodiments of the present invention provide for a lighting system in which LEDs face, and the majority of light form the LED light source is incident on, a textured surface of a back reflector while producing minimal glare and minimal imaging of the light source. Such a reflector may be referred to as a retro-reflector. The reflector for the light fixture can be made from a relatively inexpensive material such as polycarbonate, which without texturing has a specular or semi-specular surface. This material can be used alone or with a metal substrate to form the reflector. The textured surface can be textured by way of an imprinted pattern or by roughening, and can be extruded. A prismatic texture may be used. The texturing can also be spatially varied.

    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: Methods and systems for emergency lighting are disclosed. Embodiments of the invention provide a solid-state lighting system, light fixture or a collection of light fixtures, with a control input that is used to cause the system to dim to a specific level during an outage in order to conserve power in a building where power is backed up by an emergency inverter or a back-up generator. With embodiments of the invention, there is no need to run a separate power feed, as might otherwise be required for keeping distributed batteries charged or for running specified emergency-only fixtures from back-up power. In some embodiments the solid-state lighting system includes an occupancy sensor wherein the specified light output level is determined at least in part based on the occupancy of a room. In some embodiments, the system can be selectively configured for the specified output level.

    Abstract: A reduced contrast LED lighting system is disclosed. A plurality optical elements in a fixture is arranged to produce a light pattern with reduced visible contrast between the various areas where light can be perceived leaving the fixture. In some embodiments of the invention the LED light source is disposed at the reflector, and in some such embodiments a partially reflective lens plate is disposed opposite the LED light source. In some embodiments the LED light source is placed opposite the reflector. The lighting system can include a lens arrangement with a partially reflective lens plate connected to a heatsink, or two lens plates adjacent to the LED light source and the heatsink. The fixture can include a plurality of light pipes or slots to direct light into spaces between the lens plates and the heatsink.

    Abstract: A lighting fixture includes an outer frame, a solid-state light source, a lens, and a sensor module connector. Driver circuitry is coupled to the outer frame and provides one or more drive signals for powering the light source. The lens is supported by and attached to the outer frame. The solid-state light source is mounted to the outer frame and at least partially surrounded by the lens, such that at least a portion of the light provided by the solid-state light source is transmitted through the lens towards an area of interest. The sensor module connector is mounted to the outer frame and configured to accept a connector from a sensor module such that when the sensor module is installed in the lighting fixture, a surface of the sensor module faces the area of interest towards which light from the solid-state light source is provided.

    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.
