Abstract
A light emitting unit is configured to be applied to a surface area of a marine vessel and includes at least one light source configured to emit anti- fouling light (e.g., UV light), and two electrically conductive plates. One side of the at least one light source is electrically connected to one of the plates and another side to the electric energy distribution arrangement of the light emitting unit. The plates are arranged to form respective capacitors with an electrically conductive area of, or over, the surface of the marine vessel, the capacitors connected in series through the electrically conductive surface area once the light emitting unit is applied to the surface the marine vessel.
Claims15
A light emitting system for a marine vessel, the system comprising:
- at least one light emitting unit, wherein the at least one light emitting element includes an electric energy distribution arrangement and at least one light emitting assembly having at least one UV-C anti-fouling light source and two electrically conductive plates, and wherein the at least one light emitting assembly is electrically connected to the electric energy distribution arrangement;
- a source of electric power;
- and
- an electric power supply element, wherein the electric power supply element and the at least one light emitting unit are arranged with respect to each other so as to enable inductive transfer of electric power from the electric power supply element to the at least one light emitting unit,
- wherein a first side of the at least one UV-C anti-fouling light source is electrically connected to one of the electrically conductive plates, and a second side is connected to the electric energy distribution arrangement, and
- wherein the electrically conductive plates are arranged to constitute respective capacitors with an electrically conductive surface formed by or over the surface area of the marine vessel, said capacitors being connected in series through the electrically conductive surface once the light emitting unit is coupled to the surface area of the marine vessel.
