Abstract: Embodiments of the invention provide a cord seal for use in a niche that houses an underwater light. The cord seal includes a main seal with a cord receiving passage including a split for a power cord. The cord seal includes a seal support positioned adjacent to the main seal and a seal cap positioned adjacent to the seal support. The seal cap secures the main seal and the seal support substantially within a hub of the niche. The seal cap deforms the main seal to provide a water-tight seal around the power cord within the hub.

Abstract: A system and method are disclosed for converting channels manufactured for connection together to produce a straight conduit into channels that may be connected together to produce an effectively curved conduit. A link is described that permits the connection between two channels to be connected with an axial offset, which cumulatively allows a plurality of channels to produce a curved conduit.

Abstract: Provided is a cord seal for use in an underwater niche that comprises a seal cap and a main seal having a front side and a rear side and the main seal further includes a plurality of apertures that extend from the front side to the rear side. The cord seal can accommodate cords of two different sizes. The main seal also includes a plurality of splits to make it easier to install the cords. The main seal deforms to provide a water-tight seal despite the presence of at least one split in the main seal. In one embodiment, additional support structures are provided including a front seal support and a rear seal support. The front seal support has a plurality of projections that extend through the main seal and the rear seal support to connect each of the structures. The projections can be used to help spread apart the seal when it is desired to remove and replace a light assembly.

Abstract: A cord seal for use in an underwater niche including a main seal and a seal cap. The main seal includes a one-piece member with passages that are accessible from one side of the main seal and an opposite side of the main seal. The main seal includes at least a first split. The seal cap is placed in physical contact with the opposite side of the main seal. The first split spans from the one side of the main seal to the opposite side and the first split begins at an edge of one of the passages and ends at an outer circumferential edge of the main seal.

Abstract: A lighting fixture includes a heat sink having a first mounting portion attached to a housing. A first circuit board containing LEDs is mounted to a first side of a second mounting portion of the heat sink. A second circuit board include an LED control circuit is mounted to a second side of the second mounting portion. A multi-layer circuit board includes a heat-dissipating core bonded to first and second dielectric substrates, which are bonded to first and second electrically conductive layers. An electrical conductor extends through a through-hole in the board to electrically connect the first and second conductive layers. An electrical insulator inside the through-hole electrically isolates the core from the conductor. A transparent cover is shaped to cause downwardly projecting light rays emitted from the LEDs to be refracted more than upwardly projecting light rays. The cover also includes vertically extending projections for horizontally refracting light.

Abstract: Covers for a container including an interior area are provided. The covers include a shaped surface for facing away from an interior area of a container. Example covers can include a substantially planar surface, a substantially concave surface, and a smooth transition from the substantially planar surface to the substantially concave surface. Further examples of covers can include a first substantially convex surface, a second substantially convex surface, and a substantially concave surface. Still further examples of covers can include a second surface for facing towards an interior area of the container wherein the second surface includes a transition that substantially follows a transition of the shaped surface.

Abstract: A housing for receiving electrical wire from a conduit includes an interior area and at least one coupling including an internal passage configured for communicating with the interior area. The coupling includes a plurality of attachment areas that have successively different sizes along the internal passage for attaching to different sized conduits.
