Abstract

A method and apparatus of lighting a marine habitat for growth utilizing an LED light system. The light system includes an LED light source, a power supply for such light source and a controller for controlling the activation status and the intensity of the LED light source.

Claims

1. A combination marine habitat and lighting system, comprising:

a marine habitat having an open top defined by a top edge; and

a lighting system comprising;

a housing connectable to the top edge being disposed submersible into the marine habitat; and

an LED light source mounted to one side of the housing which is transparent watertight, the LED light source comprising at least one light engine having a plurality of individual LEDs.

2. The combination marine habitat and lighting system of claim 1, further comprising:

a power supply sufficient to drive the LEDs; and

a controller connected with the power supply for controlling activation status and intensity of one or more of the individual LEDs.

3. The combination marine habitat and lighting system of claim 1, wherein the housing is waterproof and the LED light source is mounted within the housing.

4. The combination marine habitat and lighting system of claim 1, wherein the LED light source, when activated, is sufficient to support marine growth.

5. The combination marine habitat and lighting system of claim 1, wherein the LED light source includes at least one of chip-based, organic or discreet LEDs.

6. The lighting system of claim 1, wherein the submersible housing is arranged in a planar configuration and is hung from the top edge of the open top of the marine habitat and disposed in parallel to the open top.

7. The lighting system of claim 1, wherein the submersible housing is arranged in a planar configuration and is hung from the top edge of the open top of the marine habitat and disposed vertically to the open top.

8. The lighting system of claim 1, wherein the submersible housing is arranged in a point configuration and disposed at bottom of the marine habitat.

9. The lighting system of claim 1, wherein the submersible housing is arranged in a planar configuration and suspended from the open top of the marine habitat.

10. The lighting system of claim 1, wherein the submersible housing is arranged in a point configuration and suspended from the open top of the marine habitat.
