Abstract

A method and lighting system for promoting survival of larvae from a plurality of eggs within a containment unit. The lighting system includes at least one lighting device emitting light energy in a pre-determined narrow range of wavelengths and a pre-determined lighting intensity that promotes the survival of the larvae within the containment unit.

Claims (22)

1. A method of promoting survival of larvae from a plurality of eggs comprising:

providing a containment unit for housing aquatic life;

placing a lighting device having a plurality of light emitting diode lighting elements, a heat sink having a plurality of fin elements, and a diffusion element in spaced relation to the containment unit; and

irradiating a plurality of larvae in the containment unit with the lighting device to promote survival of the larvae;

wherein the lighting device irradiates a spectrum having a first peak of pre-determined intensity on the larvae selected from the group consisting of 620 nm to 660 nm and a second peak from the group consisting of 430 nm to 470 nm;

wherein the first peak being at 100% of a relative luminous power of the spectrum and the second peak being at 40% of a relative luminous power of the spectrum.

2. The method of claim 1 wherein the pre-determined intensity of the first peak is in a range between 575 lux and 625 lux.

3. The method of claim 1 wherein the pre-determined intensity of the first peak is in a range between 875 lux and 925 lux.

4. The method of claim 1 wherein the larvae is red drum larvae.

5. The method of claim 1 wherein the heat sink is made of a plastic material.

6. The method of claim 1 wherein the diffusion element is a frustoconical shape having a sidewall that extends from a first end outwardly and downwardly from the heat sink to an open second end having a diameter greater than the diameter of the first end.

7. A method of promoting survival of larvae from a plurality of eggs comprising:

providing a containment unit for housing aquatic life;

placing a lighting device having a plurality of light emitting diode lighting elements, a heat sink having a plurality of fin elements, and a diffusion element in spaced relation to the containment unit; and

irradiating a plurality of larvae in the containment unit with the lighting device to promote survival of the larvae;

wherein the lighting device irradiates a spectrum having a first peak at 630 nm with the 630 nm peak at 100% of a relative luminous power of the spectrum and a second peak at 450 nm with the 450 nm second peak at 40% of a relative luminous power of the spectrum.

8. The method of claim 7 wherein the lighting device irradiates a pre-determined intensity on the larvae.

9. The method of claim 8 wherein the pre-determined intensity of the first peak is in a range between 575 lux and 625 lux.

10. The method of claim 8 wherein the pre-determined intensity of the first peak is in a range between 875 lux and 925 lux.

11. The method of claim 8 wherein the larvae is red drum larvae.

12. The method of claim 7 wherein the heat sink is made of a plastic material.

13. The method of claim 7 wherein the diffusion element is a frustoconical shape having a sidewall that extends from a first end outwardly and downwardly from the heat sink to an open second end having a diameter greater than the diameter of the first end.
