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. A portion of the nozzle can be transparent, allowing the light from the light source member to emanate radially, as well as longitudinally.

Claims

1. An air moving device comprising:

an outer housing having an outlet and an annular interior wall therein defining an interior space extending axially to the outlet;

a plurality of stators extending axially through the interior space;

an impeller configured to move air along a first flow path extending through the interior space to the outlet; and

an inner housing located downstream of the impeller, the inner housing having;

an inside chamber defining a second flow path extending axially through the inside chamber to the outlet,

an upstream opening configured to divert some of the moving air from the first flow path to the second flow path; and

a light source positioned downstream of the inside chamber within the second flow path.

2. The air moving device of claim 1, wherein a top of the annular interior wall is positioned downstream of the impeller.

3. The air moving device of claim 1, wherein the light source comprises an LED.

4. The air moving device of claim 1, wherein the annular interior wall has a venturi section.

5. The air moving device of claim 1, wherein the inside chamber has an hourglass profile.

6. The air moving device of claim 1, wherein the plurality of stators are positioned within the interior space equidistantly in a circumferential pattern.

7. The air moving device of claim 1, wherein the annular interior wall is surrounded by the plurality of stators.

8. The air moving device of claim 1, wherein the plurality of stators are positioned radially outward from the light source.

9. The air moving device of claim 1, wherein the plurality of stators extend completely through the interior space to the outlet.
