Unmanned aerial vehicle with lighting and cooling therefor
An unmanned aerial vehicle (UAV) that includes a light and a cooling system is described. The light fitted to the UAV may be bright since heat it generates will be cooled by thermal conduction, convection and/or heat absorption. The light may be cooled by the airflow generated by the propellers. The cooling system of the lighted UAV may include radiator that may conduct heat to the environment and/or include an internal liquid cooling system. The cooling system may include dedicated fans to cool the lights.
1. A water and lighting display, comprising:
one or more nozzles that are each configured to emit a stream of water, thereby providing one or more emitted streams of water; and
an unmanned aerial vehicle (UAV) system, comprising:
a UAV including one or more propellers having propeller blades that generate airflow when the propeller blades spin;
a lighting and cooling system connected to the UAV, wherein the lighting and cooling system includes:
one or more lights that generate heat;
a thermally conductive plate that is attached to the one or more lights, that extends between the one or more lights and around their periphery to provide thermal conduction of heat away from the one or more lights, that positions the one or more lights under the propeller blades to provide convection cooling from the airflow generated by the propeller blades, and that has a surface adapted to absorb heat from the one or more lights;
wherein the UAV system flies as part of the water and lighting display so that the one or more lights illuminate the one or more emitted streams of water.
2. The water and lighting display of claim 1 , wherein the UAV includes at least one light that is configured to illuminate objects viewable from the ground.
3. The water and lighting display of claim 1 ,
wherein the one or more lights are LEDs and/or lasers.
4. The water and lighting display of claim 1 , wherein the UAV further includes a liquid cooling system that transfers heat away from the one or more lights.
5. The water and lighting display of claim 1 , wherein the UAV further includes a dedicated fan that is positioned in proximity to the one or more lights to provide additional cooling.
6. The water and lighting display of claim 1 , further comprising:
a reservoir that contains water and that includes a water surface; and
a vessel that is connected to the UAV by a tether, that travels at or below the water surface, and that includes a power supply;
wherein the vessel provides power to the UAV from the power supply through the tether.
7. The water and lighting display of claim 6 , wherein the UAV includes at least one light that is configured to illuminate objects viewable from the ground.
8. The water and lighting display of claim 7 , wherein the UAV includes a liquid cooling system that transfers heat away from the one or more lights and/or a dedicated fan that is positioned in proximity to the one or more lights.
9. The water and lighting display of claim 6 , wherein the vessel includes a power supply and provides power to the UAV from the power supply through the tether.
10. The water and lighting display of claim 6 , wherein the UAV tows the vessel.
11. The water and lighting display of claim 6 , wherein the vessel includes a vessel light.
12. The water and lighting display of claim 11 , wherein the vessel is at or below the surface of the water and the vessel light is cooled by the water.
13. The water and lighting display of claim 6 , wherein the vessel tows the UAV.
14. The water and lighting display of claim 6 , wherein the vessel is below the surface of the water.
15. The water and lighting display of claim 1 , wherein the one or more lights are cooled by water from the one or more water streams.
16. The water and lighting display of claim 1 , wherein the one or more emitted streams of water are shaped as a fan.
