Abstract: A single board light engine includes an AC to AC step driver that selectively powers multiple LED segments by controlling tap points between the LED segments as the input voltage goes from zero crossover to maximum voltage and returns to zero crossover. The step driver may power a first LED segment, a second LED segment, both the first and second LED segments, or none of the LED segments depending upon the input voltage level. The LEDs within an LED segment may share a characteristic that differs from a characteristic shared by LEDs in another segment, which allows the LED fixture to provide a variety of lighting effects.

Abstract: A ceiling surface-mounted fixture housing capable of supporting decorative trim of differing shapes and sizes and further being capable of surface mounting to ceiling drywall about a recessed junction box mounted in the ceiling or to inverted T-grid ceiling systems, the invention provides flexibility and function and ease of installation. In a preferred embodiment of the invention, a fixture housing having a substantially central aperture formed in a major planar floor thereof is mounted by conventional fasteners over a junction box which has previously been installed in a recess of a drywall ceiling or the like. Wiring for the junction box extends into the fixture housing from the junction box and is joined to wiring carried by a wireway cover which joins mechanically to the fixture housing, the wiring thus being carried within a “box” formed by the fixture housing and the wireway cover. Lamping and ballast are mounted to an exterior major surface of the wireway cover.

Abstract: A reflector for a light fixture having elongated light elements, wherein the light fixture opens at the ceiling surface and is recessed thereabove, includes a generally cylindrical bottom section defining a circular opening. A substantially enclosed top section defines a generally rectangular, corrugated top surface and a side portion tapering inwardly from the bottom section to the top surface.

Abstract: A recessed lamp fixture having a minimal plaster frame and a lamp housing. The plaster frame comprising a mounting bracket is adapted to receive a variety of differently sized and shaped lamp housings. The housing comprises an integrated lamp and trim assembly that is retained within the housing by a biased retaining spring. The housing is designed with minimal openings for reduced heat loss and air flow. The frame further comprises an integrated junction box and hanger bar system adapted to mount the fixture behind a panel. The junction box and the lamp housing also comprise an electrical power line retaining means to securely fasten the line to the box and housing. The hanger bar is slideably attached to the frame with ends that are designed to engage ceiling and wall supporting structures without the need for additional fasteners.

Abstract: The portable infant carrier is made with a mesh body of three-dimensional shape which is molded with the frame of the seat. The mesh body conforms to the shape of the individual infant and thus permits an infant to be carried in a supported, semi-fetal position. A handle is provided by which the carrier can be transported in a pendulum-like manner. The seat may also be pivoted into one of a plurality of reclining positions relative to the leg support.
