Abstract

An air moving device includes a housing member, a rotary fan assembly, and a nozzle. The air moving device further includes a light source member mounted within the nozzle. The light source member can be placed within a flow of air moving out the end of the nozzle in a generally columnar pattern. The flow of air can be used to cool the light source member.

Claims

1. (canceled)

2. A method of moving air, comprising:

rotating an impeller inside a housing to cause a volume of air to enter an inlet end of the housing;

directing the volume of air through the housing toward a nozzle;

directing a main portion of the volume of air through a main flow outlet path that annularly surrounds a bypass flow channel;

directing the main portion of the volume of air out of an outlet end of the nozzle in a generally columnar manner;

directing a bypass portion of the volume of air through the bypass flow channel toward the outlet end of the nozzle;

passing at least some of the bypass portion of the volume of air over a heat sink;

impinging at least some of the bypass portion of the volume of air on a light unit; and

directing the bypass portion of the volume of air out of the outlet end of the nozzle.

3. The method of claim 2, wherein rotating the impeller comprises rotating one or more rotor blades.

4. The method of claim 2, further comprising transferring heat from the light unit to the bypass portion of the volume of air via the heat sink.

5. The method of claim 2, wherein passing at least some of the bypass portion of the volume of air over the heat sink comprises passing the at least some of the bypass portion of the volume of air through elongated channels.

6. The method of claim 2, wherein directing the main portion of the volume of air out of the outlet end of the nozzle in the generally columnar manner comprises straightening the main portion of the volume of air through the nozzle.

7. The method of claim 6, wherein straightening the main portion of the volume of air through the nozzle comprises flowing the main portion of the volume of air over one or more elongated stators within the nozzle.

8. The method of claim 2, further comprising straightening the main portion of the volume of air through the housing.

9. The method of claim 8, wherein straightening the main portion of the volume of air through the housing comprises flowing the main portion of the volume of air over one or more elongated stators within the housing.

10. A method of moving air, comprising:

flowing a volume of air into an air moving device;

directing a first portion of the volume of air through a first flow path;

directing the first portion of the volume of air out of a nozzle in a generally columnar manner;

directing a second portion of the volume of air through a second flow path and over a thermally conductive member that is in thermal communication with a light unit, the second flow path fluidly separated from the first flow path; and

directing the second portion of the volume of air out of the nozzle.

11. The method of claim 10, wherein flowing the volume of air into the air moving device comprises rotating an impeller.

12. The method of claim 10, further comprising conducting heat from the light unit to the second portion of the volume of air via the thermally conductive member.

13. The method of claim 10, wherein directing a second portion of the volume of air over a conductive member comprises passing the second portion of the volume of air through a heat sink.

14. The method of claim 10, wherein directing the first portion of the volume of air out of the nozzle comprises straightening the first portion of the volume of air through the nozzle.

15. The method of claim 14, wherein straightening the first portion of the volume of air through the nozzle comprises flowing the first portion of the volume of air over one or more elongated stators within the nozzle.

16. The method of claim 10, further comprising straightening the first portion of the volume of air through a housing of the air moving device.

17. The method of claim 16, wherein straightening the first portion of the volume of air through the housing comprises flowing the first portion of the volume of air over one or more elongated stators within the housing.

18. A method of moving air, comprising:

directing a first portion of a volume of air through a first flow path of an air moving device;

directing the first portion of the volume of air out of the air moving device in a generally columnar manner;

directing a second portion of the volume of air through a second flow path and over a thermally conductive member that is in thermal communication with a light unit located within the air moving device, the second flow path fluidly separated from the first flow path; and

directing the second portion of the volume of air out of the air moving device.

19. The method of claim 18, further comprising transferring heat from the light unit to the second portion of the volume of air via the thermally conductive member.

20. The method of claim 18, wherein directing the first portion of the volume of air out of the air moving device comprises straightening the first portion of the volume of air through the air moving device.

21. The method of claim 20, wherein straightening the first portion of the volume of air through the air moving device comprises flowing the first portion of the volume of air over one or more elongated stators within the nozzle.
