Abstract

An integrated ceiling device (80, 120) includes an electronics assembly (56) and a mechanical arrangement (20). The mechanical arrangement includes a housing (22), a heat dissipating structure (24), and support arms (26). The housing is configured to retain the electronics assembly. The heat dissipating structure includes a lamp seat (50) for receiving a light source (54), and a central opening (34) surrounded by fins (36). The support arms extend between and interconnect the housing with the heat dissipating structure. The housing is positioned within the central opening and is spaced apart from the fins of the heat dissipating structure to enable a free flow of air in an air gap (42) between the housing (22) and the structure (24). The electronics assembly may include a plurality of elements (160, 162, 164, 166) retained in the housing which are spaced apart from the heat dissipating structure.
