Integrated ceiling device with mechanical arrangement for a light source

A light emitting apparatus comprising:

• a device housing that retains a power supply;
• a heat dissipating structure that is coupled to the device housing with a plurality of support arms that hold the device housing and heat dissipating structure in a coaxial relationship, the device housing being within an inner periphery of the heat dissipating structure, wherein a plurality of through air openings between the device housing and the heat dissipating structure permit air that is heated by operation of the light source to rise and flow through the plurality of through air openings to cool the device housing and the heat dissipating structure by convection, the plurality of through air openings allow for unobstructed air flow from below the light emitting apparatus, past the heat dissipating structure, and exit above the light emitting apparatus;
• a first light source coupled to a bottom face of the heat dissipating structure;
• an optical lens coupled to the heat dissipating structure and configured to direct light emitted by the first light source downwardly toward a floor below;
• an electrical switch disposed on an exterior surface of the device housing, and configured to controllably change a mode of operation of an electronic device coupled to the light emitting apparatus;
• and
• a second light source coupled to a bottom face of the device housing and configured to direct light toward a path of egress below, the second light source is connected to a backup power supply that supplies electricity to operate the second light source upon interruption of power to the first light source.

A light emitting apparatus comprising:

• a device housing that retains a power supply configured to power a light source;
• a heat dissipating structure that is coupled to the device housing by a plurality of support arms that hold the device housing and heat dissipating structure in a coaxial relationship, the device housing being within an inner periphery of the heat dissipating structure and having a plurality of through air openings therebetween;
• the light source, the light source being coupled to a bottom face of a heat dissipating structure;
• an optical lens coupled to a perimeter of the heat dissipating structure;
• an electrical switch disposed on an exterior surface of the device housing, and configured to controllably change a mode of operation of an electronic device coupled to the light emitting apparatus;
• and
• the electronic device, wherein upon energizing of the light source, the optical lens directs light emitted by the light source toward a floor below, wherein
• the plurality of through air openings are each between the device housing and the heat dissipating structure and sized to permit air to flow therethrough to cool the device housing and the heat dissipating structure by convection, the plurality of through air openings are arranged such that a rise in temperature due to operation of the light source causes ambient temperature air to flow unobstructed upward from below the light emitting apparatus, past the heat dissipating structure, and exit above the light emitting apparatus.
