4. The lighting assembly according to claim 3 , wherein the at least one sealant element comprises a first sealing element positioned between the at least one chip-on-board light-emitting device and the housing and a second sealing element positioned between the at least one chip-on-board light-emitting device and the at least one lens element.
5. The lighting assembly according to claim 2 , further comprising a substantially transparent material positioned adjacent to the light-emitting area, between the at least one lens element and the light-emitting area.
6. The lighting assembly according to claim 5 , at least one sealant element positioned between the at least one chip-on-board light-emitting device and one or more of the housing and the at least one lens element.
7. The lighting assembly according to claim 6 , wherein the at least one sealant element comprises a first sealing element positioned between the at least one chip-on-board light-emitting device and the housing and a second sealing element positioned between the at least one chip-on-board light-emitting device and the at least one lens element.
8. The lighting assembly according to claim 1 , wherein the at least one chip-on-board light-emitting device has a power consumption of at least about 100 watts.
9. The lighting assembly according to claim 2 , wherein the housing is generally cylindrical and wherein the lighting assembly further comprises a mounting component sized and configured to thread into a drain port of a boat.
10. The lighting assembly according to claim 9 , wherein the housing and the metal substrate collectively define an interior chamber and the at least one port comprises a plurality of ports wherein each of the plurality of ports connects to the interior chamber.
11. The lighting assembly according to claim 10 , wherein less than 95% of the metal substrate is exposed to the interior chamber.
12. The lighting assembly according to claim 1 , wherein the at least one chip-on-board light-emitting device includes solder pads and wherein the lighting assembly further comprises a respective electrical conductor soldered to each of the solder pads.
13. A marine system, comprising:
A marine vehicle;
At least one lighting assembly attached to the marine vehicle, wherein the at least one lighting assembly comprises:
a housing;
at least one chip-on-board light-emitting device comprising a metal substrate and a light-emitting area bonded to at least a portion of the metal substrate;
wherein
the at least one chip-on-board light-emitting device is positioned at least partially within the housing;
the housing includes at least one port configured to allow an ambient environment to contact the metal substrate;
the light-emitting area of the at least one chip-on-board light-emitting device is sealed from the ambient environment.
14. The marine system according to claim 13 , further comprising at least one lens element positioned adjacent to the light-emitting area.
15. The marine system according to claim 14 , further comprising a first sealing element positioned between the at least one chip-on-board light-emitting device and the housing and a second sealing element positioned between the at least one chip-on-board light-emitting device and the at least one lens element.
16. The marine system according to claim 14 , further comprising a substantially transparent material positioned adjacent to the light-emitting area, between the at least one lens element and the light-emitting area.
17. The marine system according to claim 13 , wherein the at least one chip-on-board light-emitting device has a power consumption of at least about 100 watts.
18. The marine system according to claim 13 , wherein the housing is generally cylindrical and wherein the at least one lighting assembly further comprises:
a mounting component sized and configured to thread into a drain port of a boat; or
fastening elements attaching the housing to a hull of a boat.
19. The marine system according to claim 13 , wherein the housing and the metal substrate collectively define an interior chamber and the at least one port comprises a plurality of ports wherein each of the plurality of ports connects to the interior chamber.
20. The marine system according to claim 19 , wherein less than 95% of the metal substrate is exposed to the interior chamber.
21. The marine system according to claim 13 , wherein the marine vehicle is a yacht, a boat, a submarine, or a personal watercraft.
