Abstract: An illumination device (b1-01) is provided which comprises a housing (b1-03) equipped with an aperture (b1-37), first (b1-33) and second (b1-35) diaphragms disposed in said housing and in fluidic communication with said aperture, and an LED (b1-15) disposed between said first and second diaphragms.

Abstract: An LED light source (101) is provided which comprises an LED module (103) containing an LED (113); a heat sink (107) disposed about the periphery of the LED module; and a tabular synthetic jet ejector (105) disposed on said LED module and being adapted to direct a plurality of synthetic jets across surfaces of said heat sink.

Abstract: A synthetic jet ejector (201) is provided which includes a housing (205) having an orifice (207) defined in a wall thereof from which a synthetic jet (209) is emitted, and a barrier (211) disposed about the orifice. The barrier has a first end which is disposed proximal to the orifice and which has a first perimeter. The barrier also has a second end which is disposed distal to the orifice and which has a second perimeter. The second parameter has a larger area than the first perimeter.
