Claim 0:
1. An integrated ceiling device comprising:
a first light source; and
a planar heat dissipating structure that includes
at least two coupled heat dissipating fins,
a ring shaped protective frame positioned at a perimeter of the heat dissipating structure, an electronic device housing that at least in part extends above the heat dissipating structure and has a vertical axis that is substantially aligned with a central vertical axis of the heat dissipating structure, the electronic device housing is distally located from the heat dissipating structure and is connected to the heat dissipating structure via at least two support arms, the electronic device housing includes an internal space that hosts a power supply for the first light source that is coupled to a bottom face of the heat dissipating structure and is oriented to emit light toward a room below, wherein
the at least two heat dissipating fins extend upward from a top face of the heat dissipating structure and radially outward with respect to the central vertical axis of the heat dissipating structure to beyond the perimeter of the heat dissipating structure toward the ring shaped protective frame, and the at least two support arms are coupled to surfaces of the electronic device housing,
a first through air opening is centrally located within the perimeter of the heat dissipating structure such that the through air opening extends from a face of a portion of the heat dissipating structure that contains the first light source to an opposite face of the heat dissipating structure,
a second through air opening is located between the heat dissipating structure and the protective frame, and
a third through air opening is located between the at least two support arms that couple the distally disposed electronic device housing to the heat dissipating structure,
the electronic device housing, the heat dissipating structure, the protective frame, the first through air opening, the second through air opening, and the third through air opening are arranged such that a rise in temperature due to operation of the first light source causes ambient temperature air from below the integrated ceiling device to be induced to flow upward through the first through air opening and the second through opening, and
at least a portion of the air that flows upward through the first through air opening and the second through air also flows through the third opening located between the at least two support arms.
