Claim 13:
14. An integrated ceiling device comprising:
a first light source;
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 optical lens,
an electronic device housing that at least in part is located 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 having an internal space that hosts a power supply for the first light source that is coupled to the bottom face of the heat dissipating structure and 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 protective frame, and the at least two support arms that are coupled to surfaces of the electronic device housing,
a first through air opening is located between the heat dissipating structure and the protective frame,
a second through air opening is located between the electronic device housing and the heat dissipating structure,
the optical lens directs light toward the room, extends below the first light source toward the room, and is secured to a retaining structure between a perimeter of the first light source the perimeter of the protective frame,
the electronic device housing, the heat dissipating structure, the protective frame, the optical lens and the first through air opening are arranged such that operation of the first light source heats ambient temperature air and induces heated air to rise from below the integrated ceiling device upward through the first through air opening, and
at least a portion of the heated air flows across the fins and through the second through air opening.
