In unillustrated embodiments, plenum chamber 111 may include a blower for propelling air, heating elements, and/or a cooling plant as desired. However, it is also contemplated that plenum chamber 111 or internal air distribution conduits 110 may be connected to a heating, cooling, or ventilation system (not shown) which is part of the building to be modified by installation of multi-utility ceiling fixture 100.

[0014] It should be noted that where a plurality of similar components such as first lighting units 106A are present, not every one of such components is called out by reference numeral. It will be understood that unnumbered components drawn similarly to numbered components are additional examples of the numbered components.

[0015] It should be noted at this point that orientational terms such as bottom and downwardly refer to the subject drawing as viewed by an observer. The drawing figures depict their subject matter in orientations of normal use, which could obviously change with changes in posture and position of the novel multi-utility ceiling fixture 100. Therefore, orientational terms must be understood to provide semantic basis for purposes of description, and do not limit the invention or its component parts in any particular way.

[0016] As depicted, housing 102 is tiered, although in other implementations, housing 102 may not be tiered, or alternatively, may include more than two tiers. Regardless of the number of tiers, bottom surface 104 will be understood to include all downwardly facing surfaces of housing 102 regardless of the number of tiers.

[0017] Unless otherwise indicated, the terms first, second, etc., are used herein merely as labels, and are not intended to impose ordinal, positional, or hierarchical requirements on the items to which these terms refer. Moreover, reference to, e.g., a second item does not either require or preclude the existence of, e.g., a first or lower-numbered item, and/or, e.g., a third or higher-numbered item.

[0018] In multi-utility ceiling fixture 100, at least one first lighting unit 106B may be recessed within housing 102. The at least one first lighting unit 106B may comprise a light discharge opening 112 flush with housing 102.
