Apparatus and method provide underwater lighting to illuminate a site within a body of water in which underwater lighting apparatus is immersed during a lighting cycle. A housing is constructed of a heat-conductive material and LED arrays are affixed to the housing, within a sealed chamber, to conduct heat from the LED arrays to the housing such that heat generated by the LED arrays during the lighting cycle will be conducted directly to the housing and dissipated by the housing to the surrounding body of water. Light provided by the LED arrays is passed through corresponding lens members located for directing light in different directions. At the same time, fouling by marine organisms is resisted.

The present invention refers to a universal submersible LED lamp/luminaire adapted to be placed inside a tube embedded in the walls or floor of a swimming pool, tubs, jacuzzi or other bodies of water, characterized in that it comprises a hermetically coupled tubular casing that defines a posterior end and an anterior end; the rear end comprises a waterproof power supply socket or female connector, configured with an arrangement of five round pins for four connection configurations and the front end comprises a waterproof sealed lens, and internally houses a panel of a plurality of LEDs and a LED lighting control electronic board is housed inside said tubular casing and is connected to the female connector and to the plurality of LEDs, and integrates a plurality of microchips, each one programmed and configured to execute and control a pattern and sequence automated switching on of the plurality of LEDs that are activated depending on the connection position of a connector of the power supply cable in the waterproof power supply socket or socket.

Lighting devices that comprise a light source and a reflector, the reflector comprising first, second and third reflector regions. In some devices, a first portion of light is reflected by the first region and then by the third reflector region, a second portion of light is reflected by the second region and forms a primary beam, and at least 5% of the first portion of light that is reflected by the third region is within the primary beam of light. In some devices, at least 5% of all light reflected by the first reflector region travels from the first reflector region directly to the third reflector region. In some devices, at least 5% of all light reflected by the third reflector region traveled directly from the first reflector region to the third reflector region. In some devices, the reflector comprises means for providing the features described above.

Nicheless lighting assemblies principally for swimming pools and spas are detailed. The lighting assemblies include features configured to dissipate heat. The assemblies additionally are designed to reduce possibility of water intrusion. Some versions of the assemblies may include thermally-conductive plastic overmolded onto at least one of a lens or a heat spreader. Versions of the assemblies additionally or alternatively may include a generally annular heat sink to which a printed circuit board containing at least one light-emitting diode (LED) is attached. Versions of the assemblies may be divided into subassemblies, one subassembly fitting into another, or include protective covers.

An underwater pendant light installation within a wall of a water feature has an installation tube in a niche tube having a facia section at the terminus of the niche tube. One terminus of the niche tube in communication with the water feature and having a water inlet coupled to a water gap section. An at least one underwater pendant or accent light having a housing, a lens body, an electronics section, an at least one heat sink, and one or more LEDs is mounted within the niche tube. The underwater pendant or accent light being coupled in a watertight fashion to a power source through the watertight coupling and being contained within the niche tube such that the water gap section surrounds at least in part the housing and permits water from the water feature to circulate in contact the housing but not penetrate into the watertight electrical connection.

A directionally adjustable pool light includes a lamp assembly having a body encircled by a collar. The collar includes a conical portion and the body partially defines a spherical space. The body has posts along an axis running centrally through the spherical space and is held against the conical portion by the posts. Rotating an adjusting screw accessible through the collar causes the body to rotate. A pivoting frame and adjustment nut couple the adjusting screw to the body, with the frame sliding relative to the body. LEDs are located substantially centrally in the spherical space, a trim cover is located over the collar, and a removable diffuser over the LEDs is surrounded by the collar.

The present invention is a modular pool skimmer faceplate cover with a pre-wired integrated underwater light. The faceplate cover of the present invention clips onto a faceplate of any pool skimmer inside a swimming pool. The faceplate cover is provided with a cavity below the faceplate cover's mouth that accommodates a light source element, and this light source element connects to a low-voltage power supply. The light source element can be a LED, and be located below or around the faceplate cover's mouth.

A light display system and device for use in a body of water or other liquid is described. The light display device may be controlled remotely via a control hub and/or control panel, or controlled by internally preprogrammed commands. A plurality of light display devices may be controlled in selected, choreographed sequences to provide various unique visual displays including, for example, geometrical patterns and/or naturalistic patterns giving the impression of organic phenomena such as swarming fireflies, bioluminescent creatures and the like.

Plastic grid or framework arrangements are used to support and position of bowls that hold flower arrangements, candles, letters, and other decorative elements. These grids are deployable in water fountains, indoor and outdoor pools, and other small bodies of water during festive occasions or for longer term decorative display. The grid themselves do not float, and are positioned below the surface of the water, and thus are not readily visible. Buoyancy is provided at the hubs that form nodes in the grids. The hubs also support floating bowls containing various decorative elements. The resulting effect is that the various decorative elements appear to be floating on the surface while the sub-surface grid structure maintains their relative positioning, keeping the bowls from clumping together at the edges or in the corners of the pool or fountain.

Disclosed herein is a pool light assembly including cooling for the illuminating structure. The assembly includes a water inlet housing having a portion on the dry side and a portion immersed in the pool water. An assembly having sealing structure creates a leak proof connection with the pool wall. The submerged portion of the assembly includes a base. The base has an exterior exposed to the pool water and an enclosed interior including the illuminating structure. A notch is provided in the exterior of the base and extends into the interior for allowing pool water in the proximity of the illuminating structure. The assembly includes sealing structure for preventing water from entering electrically active elements, while allowing pool water to act as a cooling element. A retaining member locks and encourages waterproof sealing of the electrically active elements. Each of the elements is provided with structure as necessary to facilitate the free flow of water through the housing.
