1. An air moving device comprising:
- a housing having a top and a bottom, the housing defining an outer wall;
an impeller positioned within said housing;
an annular interior wall having a top and a bottom;
stators positioned between the interior wall and the outer wall of the housing;
the impeller positioned such that air from the impeller moves along a first path between the annular interior wall and the outer wall and along a second path within said annular interior wall;
the annular interior wall defining a channel narrowing from its top to create an air flow; and
a light source positioned downstream and below a narrowest portion of said channel, said light source positioned to be within the air flow and spaced below the bottom of the annular interior wall.

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.

6. An air moving device comprising:
-
a housing having an inlet, an outlet, an inner wall, and an outer wall; an impeller assembly positioned within the housing between the inlet and the outlet; a light assembly positioned at least partially within the housing downstream of the impeller assembly between the impeller assembly and the outlet, the light assembly having an interior; a primary air flow path defined between the light assembly and the inner wall of the housing; a plurality of stator vanes positioned within the housing in the primary air flow path between the impeller assembly and the outlet; and an opening between the impeller assembly and the light assembly within the housing, the opening configured to direct a portion of air from the primary flow path into the interior of the light assembly; wherein the interior of the light assembly is separated from the primary flow path by a wall; and wherein, when the air moving device is installed, the inlet is positioned above the impeller assembly, the impeller assembly is positioned above the stator vanes, the stator vanes are positioned above the outlet, and the light assembly is positioned between the stator vanes. - View Dependent Claims (7, 8, 9, 10, 11)
