  • Patent number: 12638167
    Abstract: Nicheless lighting assemblies principally for swimming pools and spa 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.

  • Publication number: 20260020123
    Abstract: A lighting device can be assigned to a light group by a controller. The controller can read a plurality of addresses associated with a plurality of lighting devices. The controller can send a set of addresses of the plurality of addresses to a computing device. Responsive to receiving a first instruction from the computing device that identifies a first address of the set of addresses, the controller can cause a first lighting device of the plurality of lighting devices to emit a first light. Responsive to receiving a second instruction from the computing device, the controller can assign the first lighting device to a first light group.

  • Patent number: 12446125
    Abstract: Methods and systems described herein provide control of a lighting system, such as a pool lighting system. The pool lighting system includes an integrated control device that includes both a transformer and a controller. Lighting devices are powered by power from the transformer using power lines and controlled using power line communication (PLC) signals sent over the same power lines.
