A lighting system for use in a high-moisture environment, such as a swimming pool, includes a lighting unit having a housing and at least one light-emitting device positioned within the housing. A power supply provides power to the light-emitting device. A receiver positioned within the housing operates with a LoRa modulation format. A mobile control unit located remote from the lighting unit is configured to transmit at least one wireless control signal to the receiver, whereby the at least one control signal controls or changes a characteristic of the at least one light-emitting device, such as an on/off state, a color, a lighting effect, or a pattern of display. Related systems and methods for installing a lighting system for use in a high-moisture environment are also disclosed.

A water spraying device and an above-ground pool including the water spraying device are provided. The water spraying device includes: a sprayer assembly having a water inlet end, a water outlet end, and a first magnetic element disposed on the water inlet end; and a mounting assembly including a first end, a second end in fluid communication with the first end, and a second magnetic element disposed on the first end of the mounting assembly. The mounting assembly defines therein a water passage to the sprayer assembly. The first magnetic element is mutually attractive to the second magnetic element such that the water inlet end of the sprayer assembly and the first end of the mounting assembly are detachably connectable via the first magnetic element and the second magnetic element.

A tanning ledge insert for a swimming pool is provided. In various embodiments, the tanning ledge includes a fiberglass insert that is adapted for use within the context of a vinyl liner pool. A depth of the tanning ledge may be, for example, between 14 and 16 inches. However, in other embodiments, the tanning ledge may be of any other suitable depth. The tanning ledge insert may include a vertical wall and a tanning ledge extending horizontally from the vertical wall. A step may be disposed adjacent the tanning ledge's upper surface. The tanning ledge insert may include a connection lip that is dimensioned for use in securing the tanning ledge insert in place within the structure of a vinyl liner pool. Methods of installing and replacing the tanning ledge insert are also provided.

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.

The disclosure aims at providing a 3D pool system for enabling users to see 3D visual effects when is use and enhancing user experience. The 3D pool system may include a pool body and a viewing device. Pool body may include an inner pool surface provided with a pattern may include first regions and second regions. First regions and second regions respectively have first boundaries and second boundaries. First regions surrounded by first boundaries are filled with a first colour, and second regions surrounded by second boundaries are filled with a second colour. Viewing device is used for viewing pattern and refracting incident light from pattern, and re is a difference in depth of field between first regions 4a and second regions 4b of pattern, thereby creating a 3D effect. The disclosure realizes a three-dimensional effect of pattern on inner pool surface at low costs.

A water playing system includes an infrared sensor for sensing people, a display module for displaying still image or moving image, a jet module for jetting the water into the water playing pool, and a control computer for controlling to display the still image or the moving image by the display module and to jet the water by the jet module when the people are sensed by the infrared sensor.

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 housing is provided having a leak detection tube in liquid communication with the inside of the housing. The housing is adapted to be affixed to a wall surface of a swimming pool over a suspected leak area below the surface of the water by a lockable connector mounted on the housing. A suitable dye substance then is inserted into the distal top or free end of the leak detection tube while the latter is positioned just below the surface of the swimming pool water by a leak specialist positioned on the deck or beam of the pool. A light fixture may be mounted in the wall surface and the aforementioned leakage test conducted to determine water leaks in the niche containing the light fixture.

A pool apparatus for users to do activities in the pool apparatus. The pool apparatus includes a pool main body, one or more than one reaction deices and a control circuit. The control circuit is connected to the reaction device and controls the reaction device according to a setting to increase additional functions of the pool apparatus. When the control circuit is connected to an external device via at least one wireless network, a user may use the external device to adjust the setting. The external device does not need to be paired with the control circuit in advance. Instead, the external device interacts with the control circuit via a protocol to access and adjust the setting.
