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.
Claims27
A device, comprising:
- a chamber having a liquid disposed therein;
- an LED array having a first surface which is in contact with said liquid;
- and
- at least one actuator adapted to dislodge vapor bubbles from said first surface through the emission of pressure vibrations.
1 more element
A device, comprising:
- a chamber having a liquid disposed therein;
- an LED array;
- and
- an actuator array adapted to cool said LED array by atomizing said liquid.
1 more element
A device, comprising:
- a chamber having a liquid disposed therein;
- a plurality of LEDs, wherein each of said plurality of LEDs has a light-emitting surface which is in physical contact with said liquid;
- and
- at least one actuator adapted to dislodge vapor bubbles from the light-emitting surfaces of said LEDs through the emission of acoustic/pressure vibrations which induce the formation of a plurality of synthetic jets which impinge on said first surface.
1 more element
A device, comprising:
- an LED array having a light emitting surface;
- an actuator array;
- and
- a window, disposed in opposing relation to said light emitting surface;
- wherein said light emitting surface, said actuator array, and said window define a portion of a chamber having a liquid disposed therein, and wherein said actuator array is adapted to atomize said liquid.
