A submersible marine lighting apparatus is provided which converts electrical input to 25 or 34 volts and provides optimal underwater illumination. The marine lighting apparatus comprises a plano-convex light-focusing lens that concentrates emitted light into a more focused beam, as well a thermal switch and COB LED.

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.

The present disclosure is directed to a stern light for illuminating a watercraft without visually impairing a passenger of the watercraft. The stern light includes a flexible pole with a hollow interior for housing wires. The wires are connected to a watercraft at one end of the pole and to a light source at another end of the pole. The light source, which may be an LED light source, is covered by a globe that at least partially refracts light. When powered, the stern light produces light capable of providing visibility of the watercraft for at least two nautical miles while also avoiding the visual impairment of watercraft passengers. Pole flexibility allows operation of the stern light during watercraft motion and in areas with potential obstructions, such as low-hanging branches.

A marine vessel includes a vessel body including a navigation light, an imager provided in a vicinity of or adjacent to the navigation light, and a light shield provided between the navigation light and the imager so as to block light from the navigation light to the imager.

A lighting system is disclosed that may be used for marine applications. The lighting system comprises a light strip support structure, a first light strip comprising a first plurality of lighting elements, including light elements of different colors, a second light strip comprising a second plurality of lighting elements, the second light strip positioned above the first light strip and configured to emit only white light, a light element controller electrically connected to the first light strip, wherein the light element controller is configured to control the illumination of the first plurality of lighting elements and not the second plurality of lighting elements and a connector configured to mate with a watercraft stern connector.

Submersible lights including housings and a multilayer stack for pressure transfer are disclosed. A transparent pressure-bearing window, a window support structure, a circuit element populated with LEDs, and a pressure support structure may be mounted inside the housing. The support structure may be structured to bear at least some of the pressure applied to the transparent window from external pressure sources. The support structures may also be adapted to transfer thermal energy to an exterior environment such as sea water.

A light emitting device (1) is provided that can be used in various contexts, including the context of realizing an anti-fouling action on surfaces. The light emitting device (1) comprises light emitting units (10) being arranged in a plane filling pattern (20) for covering at least a substantial portion of a surface.

Further, it may be so that at least one of the connection areas (12, 13) of the individual light emitting units (10) is electrically connected simultaneously to respective connection areas (12, 13) of at least two other light emitting units (10).

A pole light and base system that includes a pole light base configured to be secured to a gunwale of a watercraft. In practice, the pole light base might include a pole light tube and a female Universal Serial Bus connector. The pole light tube may have electrical contacts configured to engage respective electrical contacting portions of an all around light pole if an all around light pole is inserted into the pole light tube. In some cases, the system might include the all around light pole and light. The electrical contacts of the tube might include a positive contact electrically coupled to a first wire and a negative contact electrically coupled to a second wire. The first and second wire may be designed to connect directly to a 12 Volt watercraft battery. They may also connect to a boat fuse box that is connected to a battery.
