Abstract

Light emitting diode systems are disclosed. An optical display system that includes a light emitting diode (LED) and a cooling system is disclosed. The cooling system is configured so that, during use, the cooling system regulates a temperature of the light emitting diode.

Claims (18)

1 . An optical display system comprising;

a LED;

a cooling system configured so that, during use, the cooling system regulates a temperature of the light emitting diode; and

a sensor in thermal communication with the light emitting diode and in electrical communication with the cooling system.

2 . The optical display system of claim 1 , wherein the light emitting diode includes a multi-layer stack of materials including a light generating region, and a first layer supported by the light generating region, a surface of the first layer being configured so that the light generated by the light generating region can emerge from the light emitting device via the surface of the first layer.

3 - 6 . (canceled)

7 . The optical display system of claim 1 , wherein the LED has an edge that is at least about one millimeter long.

8 . The optical display system of claim 1 , wherein the LED has an edge that is at least about 1.5 millimeters.

9 . The optical display system of claim 1 , wherein the cooling system comprises a fan.

10 . The optical display system of claim 1 , wherein the cooling system is a liquid based cooling system.

11 . The optical display system of claim 1 , wherein the cooling system is a thermoelectric cooler.

12 . (canceled)

13 . The optical display system of claim 1 , wherein the LED is selected from the group consisting of OLEDs, flat surface-emitting LEDs, HBLEDs, and combinations thereof.

14 . The optical display system of claim 1 , wherein the optical display system is configured to be used in a rear projector.

15 . The optical display system of claim 1 , wherein the optical display system is configured to be used in a rear projection television.

16 . The optical display system of claim 1 , wherein the optical display system is configured to be used in a front projector.

17 . The optical display system of claim 1 , wherein the optical display system is configured to be used in a home theatre system.

18 . The optical display system of claim 1 , wherein the optical display system is configured to be used in a portable projector.
