Abstract
A device, comprising (a) a chamber having a liquid disposed therein, (b) an LED array having a first surface which is in contact with said liquid, and (c) at last one actuator adapted to dislodge vapor bubbles from said first surface through the emission of pressure vibrations.
Claims20
A device, comprising:
- a first set of LED arrays adapted to emit light over a first principle bandwidth;
- a second set of LED arrays adapted to emit light over a second principle bandwidth;
- a third set of LED arrays adapted to emit light over a third principle bandwidth;
- and
- a synthetic jet ejector;
- wherein each member of said first, second, and third sets of LED arrays comprises a transparent, essentially planar substrate having a first light emitting surface with a first set of LEDs disposed thereon and a second light emitting surface with a second set of LEDs disposed thereon, wherein the members of said first, second and third sets of LED arrays are arranged in parallel, and wherein said synthetic jet ejector is adapted to emit a synthetic jet across the first or second light emitting surface of at least one member of at least one of said first, second and third sets of LED arrays.
