Integrated ceiling device with mechanical arrangement for a light source
An integrated ceiling device includes integrated ceiling device including an electronic device housing, a heat dissipating structure, a light source, and a reflection/refraction assembly. An air gap is defined between the electronics housing and other components allowing ambient air to flow therethrough for cooling.

the air gap is positioned and sized to permit air to rise unobstructed from below the light emitting apparatus to above the light emitting apparatus for not less than three hundred and twenty degrees around the outer periphery of the electronic device housing.
