The lens apparatus also includes a compression surface configured to compress the substrate to a heat sink to facilitate heat dissipation from the LED and a fastening feature configured to fasten the lens apparatus to the heat sink to provide an environmentally protective seal, so that when the lens apparatus is fastened to the heat sink the alignment feature aligns the LED to the selected position, the compression surface compresses the substrate to the heat sink, and the protective seal protects the LED from environmental conditions.

An underwater light probe includes a body, a heat sink, and a lens assembly. The heat sink forms at least a portion of the body and includes a longitudinally extending mounting base having a plurality of laterally facing mounting surfaces configured to mount a plurality of laterally facing light elements thereon. The lens assembly is configured to couple to the body and defines a bore configured to receive the longitudinally extending mounting base and the plurality of laterally facing light elements mounted thereon and provide a watertight seal therearound when coupled to the body.

An encapsulated LED switch that incorporates a MOSFET power drivers, high current transistors, or other suitable power drivers in a PCB that attaches to the LED switch such that a low power LED switch controls the output of a high-power driver. The selected power driver PCB can be adapted to different load requirements by making simple changes. The PCB's can be interchanged to provide for a predetermined output power required for a particular application. In addition, the wire gauge size of the wires attached to the MOSFET power driver PCB can also be varied to match intended load requirements. For applications in which the LED switch is used in hostile environments, such as marine applications, the LED switch and its associated power driver PCB are encapsulated to protect the circuitry from environmental factors such as high humidity, salt water, etc.
