Abstract: An underwater light including a programmable controller and a replaceable light-emitting diode (LED) printed circuit board assembly (PCBA) is provided. The light includes a controller PCBA in communication with the LED PCBA, and a connector for connecting the controller PCBA to the LED PCBA. An optically-transparent potting compound encapsulates the LED PCBA, and the LED PCBA can be safely replaced by removing a rear housing of the underwater light.

Abstract: An underwater light having a replaceable light-emitting diode (LED) module and cord assembly is provided. The underwater light includes a lens, a bezel, a screw, a cable attachment assembly, a mounting flange, a rear housing, a fastening assembly, an internal lens, a printed circuit board (PCB) including light-emitting diodes (LEDs) mounted thereon, a heat sink, and an electronics assembly. The assembly of the underwater light provides for the dissipation of heat away from the PCB thereby cooling the LEDs and electronic components mounted thereon. The electrically non-conductive nature of the exterior components of the underwater light permit the underwater light to be installed in any location in a pool or spa. Since the exterior of the underwater light is electrically non-conductive, no specific bonding or grounding of the underwater light is necessary.

Abstract: A sectional heat insulation jacket comprises a set of multi-layer insulation sections in which the layers are bound together by a fastening and fixing device. Adjacent insulation sections connect and they separate by assembling joints that are self-sealing. A mutual position of the adjacent sections is reliably fixed by the connecting device at each stage of heating. The self-sealing is accomplished by side flexible layers which incline under a sharp angle to the surface of an upper flexible layer. The sizes of the assembling joints between adjacent sections at levels of the upper and the bottom flexible layers are equal to the temperature expansions of these layers in longitudinal and transverse directions, correspondingly under the insulated entity's heating until an operating temperature is reached. A conical, helical spring shaped fastening rod further increases a length of metallic inclusions with high thermal conductivity form an insulated entity and reduces heat loss.

Abstract: A sectional heat insulating jacket is a removable, repeatedly used for various process equipment heat(sound-) insulation product<been made of a set of the insulation sections (2), which are separated at the stage of installation by the assembling joints (22) and are connected among themselves in an organic whole using the connecting means (24). The insulating sections (2)—polyhedral, closed protective housings (4), are formed by thread-stitched seams (6) and comprise the bottom (8), upper (10), and lateral (12) flexible layers. There is a middle heat (sound)insulation-forming layer, placed inside the housing (4). The layers (8), (10), and (12) are fastened among themselves by the fastening means (16), consisting of the fastening rod (18) and the fixing means (20) and providing invariable thickness of the insulation section (2) and its all layers mutual work during thermal deformation.
