Abstract:
The electrical switch device can includes a method and dimmer determination device that automatically determining a dimmer level for an electronic device. A signal is received and, when coupled with the time of day and the ambient light level, an appropriate algorithm can be selected. The output of the algorithm provides the dimmer level, which is sent to a controller for output to the electrical device. Based on user feedback, the algorithms and thresholds used to determine the dimmer level can be adjusted, created, and deleted to provide a more accurate dimming level in the future.

A method of manufacturing a ground power connector having a female socket, the method comprising: providing an internal block comprising a cavity; inserting at least a portion of a female socket into the cavity of the internal block; sealing the cavity of the internal block; and molding a rubber plug body onto an exterior of the internal block so that the plug body flexibly supports the female socket in the cavity.
Abstract:
A wall notification device described herein can draw a lower current by providing a more efficient reflector configuration. The reflector is designed to be positioned on a wall and provide sufficient light output in each of the requisite directions, as required by the UL 1971 standard. The notification device has a reflector unit having a base having a curved portion centered on the vertical axis and a flat portion extending from the curved portion; a reflective flange extending from a location near a top side of the base; a first and second specular protrusion extending from the curved portion of the base; a third and fourth specular protrusion extending from the base; a fifth and sixth specular protrusion extending from the curved portion of the base; and a sixth and seventh specular protrusion extending form the flat portion of the base.
Abstract:
A light fixture includes a member having a substantially frusto-conical shape. A channel extends between a wide top end of the member and a narrower bottom end of the member. The member includes multiple surfaces (“facets”) disposed around its outer surface. Each facet is configured to receive one or more light emitting diodes (“LEDs”) in a linear or non-linear array. Each facet can be integral to the member or coupled to the member. The channel is configured to transfer heat generated by the LEDs through convection. Fins can be disposed within the channel, extending from the inner surface of the member to an inner channel. The fins are configured to transfer heat away from, and provide a greater surface area for convecting heat away from, the member. For example, one or both of the channels can transfer heat by a venturi effect.
Abstract:
Optic entrance features may be used to optically control light transfer from a light source to a light emitting panel (LEP). In a particular embodiment, an LEP includes a first LEP side configured to emit light. The LEP also includes a second LEP side. The first LEP side and the second LEP side are opposite sides of the LEP. The LEP further includes a cutout area providing an air gap in the LEP through the first LEP side and the second LEP side. The LEP also includes a light receiving side. The cutout area is proximal to the light receiving side, and the light receiving side is configured to pass light through towards the cutout area.
Abstract:
A recessed light fixture includes an LED module, which includes a single LED package that is configured to generate all light emitted by the recessed light fixture. For example, the LED package can include multiple LEDs mounted to a common substrate. The LED package can be coupled to a heat sink for dissipating heat from the LEDs. The heat sink can include a core member from which fins extend. Each fin can include one or more straight and/or curved portions. A reflector housing may be coupled to the heat sink and configured to receive a reflector. The reflector can have any geometry, such as a bell-shaped geometry including two radii of curvature that join together at an inflection point. An optic coupler can be coupled to the reflector housing and configured to cover electrical connections at the substrate and to guide light emitted by the LED package.

At least one of the first and second gripping elements has a configuration that makes at least two points of contact with the cable. A system for gripping a cable and having a gripping device fastened to a support structure, where the gripping device has a first jaw with a first gripping element, a second jaw with a second gripping element, and at least one fastener for fastening the first and second jaws to each other. At least one of the first and second gripping elements has a configuration that makes at least two points of contact with the cable.
Abstract:
A light module includes a cover, a circuit board, a gasket, a bottom covering, and an optional optic assembly. The cover includes an inner and an outer wall extending outwardly from the cover, where the outer wall surrounds the inner wall and forms a groove therebetween. The circuit board is positioned within the inner wall's profile and includes a plurality of LEDs. The gasket is disposed within the groove. The bottom covering is positioned adjacent to the circuit board and is coupled to the cover. The gasket provides a seal between the cover and the bottom covering. The optic assembly is disposed within the inner wall's profile and between the cover and the circuit board. The optic assembly includes one or more apertures and one or more optics disposed around at least some of the apertures. Each optic is aligned with one or more LEDs.
