Underwater Light Having a Replaceable Light-Emitting Diode (LED) Module and Cord Assembly

An underwater light comprising:

• a bezel having a screw aperture sized and shaped to receive a screw for mounting the underwater light to a niche, a plurality of recesses, and a first annular projection, the bezel sized and shaped to cover niches or recesses of pools or spas having different diameters, the bezel formed from an electrically insulative polymer material;
• a lens having a central lens portion, a peripheral annular wall, a plurality of tabs, and a central recess defined by the central lens portion and the peripheral annular wall, the bezel positioned about the central lens portion of the lens, the lens formed from an electrically-insulating material, the lens including a coating or layer preventing formation of condensation on an interior portion of the lens;
• a rear housing in water tight communication with the peripheral annular wall of the lens, the rear housing including a recessed portion configured to couple to a cable attachment assembly;
• a rear housing plate having a plurality of notches, a second annular projection, an internal lens assembly and formed from an electrically insulative and thermally conductive polymer material, the rear housing plate positioned between the lens and the rear housing, the second annular projection being received by the central recess of the lens, the plurality of notches engaging the rear housing so that the rear housing plate is in water tight communication with the rear housing;
• a printed circuit board having a plurality of light-emitting diodes (LEDs), the internal lens assembly of the rear housing plate directing or focusing light generated by the plurality of LEDs, the printed circuit board potted by an optically-transparent potting compound;
• a back plate formed of a thermally conductive material and in contact with the printed circuit board;
• a heat sink in contact with the back plate, the back plate transferring heat from the printed circuit board to the heat sink, the heat sink positioned on a central inner surface of the rear housing and including a plurality of fins, the heat sink formed from a thermally conductive and electrically insulative material;
• an electronics assembly including control and network electronics and controlling the underwater light, the electronics assembly received and housed by the rear housing, the electronics assembly potted with a potting compound;
• a mounting flange including a plurality of fingers and a central aperture, the plurality of fingers of the mounting flange engaging the plurality of recesses of the bezel and the central aperture receiving the first annular projection of the bezel, the mounting flange formed from a thermally conductive and electrically insulative polymer material;
• and
• a positioning assembly allowing for vertical movement of the underwater light during installation.
