Abstract
Light emitting diode lighting systems and methods useable to replace incandescent bulbs or other types of LED light sources in enclosed environments, such as in underwater lighting niches used in swimming pool, spa, fountain and other underwater lighting applications.
Claims7
An LED lighting system positionable in a niche that has a niche lens through which light passes, said LED lighting system comprising:
- a housing having air outflow openings formed therein;
- an LED driver circuit board having a plurality of LEDs mounted thereon, circuitry components for driving said LEDs and a plurality of flow-through openings through which air may flow through the LED driver circuit board to carry heat away from the LEDs and circuitry;
- a fan positioned below the LED driver circuit board;
- and
- a lens having a light diffusing region for diffusing light from the LEDs in advance of the niche lens and a plurality of air inflow openings formed in the lens;
- wherein the fan is operative to circulate air inwardly though the inflow openings formed in the lens, then though the flow through openings formed in the LED driver circuit board and then out of the outflow openings formed in the housing.
