Abstract
A light source (101) is provided which comprises (a) a housing element (107); (b) a heat sink (109); (c) a first flow channel element (111) which, alone or in combination with said housing element, creates (i) a first set of flow paths (221) for the flow of fluid in a first direction through the light source, and (ii) a second set of flow paths (223) for the flow of fluid in a second direction through the light source; (d) a set of synthetic jet actuators (143, 145) having at least one member and being in fluidic communication with said first set of flow paths; and (e) a set of LEDs (113) containing at least one member and being in thermal contact with said heat sink.
