Abstract
Lighting modules having a first LED support having a first plurality of LEDs mounted thereon adjacent a center of the first LED support, a second LED support having an outer edge and an inner opening, and a second plurality of LEDs mounted thereon adjacent the inner opening of the second LED support, the second LED support being spaced apart from the first LED support, the inner opening of the second LED support being larger than the region of the first LED support having the first plurality of LEDs, whereby light from the LEDs on the first LED support may pass though the inner opening of the second LED support. Additional larger LED supports with LEDs may be added, and the assembly of the LED supports sealed with the outer edges of the LED supports extending outward for immersion and cooling in water when incorporated in a larger sealed assembly.
