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.
Claims20
A lighting system for a marine habitat having an open top, the lighting system comprising:
- a housing disposed over the open top of the marine habitat;
- an LED light source disposed on an inner side of the housing and facing the open top of the marine habitat, the LED light source comprising a light engine having a plurality of individual LEDs capable of providing light within a spectral range of about 380 nm to about 690 nm, wherein a spectral content of the light engine is controlled by independent control of the individual LEDs within the light engine, each of the individual LEDs being of a type emitting its own particular wavelength within the spectral range;
- and
- a fan for dissipating heat generated by the LED light source by drawing ambient air through vents in the housing.

A system comprising:
- a marine habitat comprising an aquarium having an open top defined by a top edge;
- a lighting system comprising:
- a light housing connectable to the top edge, the light housing including an inner side and an opposite outer side;
- an LED light source mounted to the inner side of the light housing, facing the marine habitat, the LED light source comprising at least one light engine having a plurality of individual LEDs, each of the LEDs capable of providing light within a spectral range of about 380 nm to about 690 nm;
- and
- driver electronics for controlling an output intensity of the light engine;
- a cooling fan for dissipating heat generated by the LED light source:
- and
- a plurality of vents disposed in the light housing;
- wherein the cooling fan is configured to cool the LED light source by drawing ambient air through the vents and over the driver electronics.
