1. A light emitting device comprising:
a heat dissipating structure coupled to at least one light source at a bottom surface of the heat dissipating structure, the at least one light source electromechanically coupled to an electronic device housing retaining at least one power supply and supported by a structure above, the heat dissipating structure is horizontally oriented and substantially planar with a central through air opening and a plurality of through air openings located along a perimeter thereof;
the at least one light source is coupled to the bottom surface of the heat dissipating structure between the central through air opening and at least one of the plurality of through air openings to illuminate a surface below the light emitting device;
at least one optical lens coupled to the heat dissipating structure is disposed between the at least one light source and the illuminated surface below;
the electronic device housing has a central vertical axis substantially aligned with a vertical central axis of the central through air opening in the heat dissipating structure, the electronic device housing, at least in part, extends above the heat dissipating structure;
the at least one power supply is coupled to the electronic device housing, the at least one power supply supplies power to the at least one light source coupled to the heat dissipating structure; and
at least one mechanical extender that is coupled to the heat dissipating structure and to the electronic device housing forms a through air gap between the heat dissipating structure and at least a portion of the electronic device housing, wherein
under a condition the light emitting device is powered, heat generated by the at least one power supply and the at least one light source induces air from below to flow across the central through air opening and the at least one of the plurality of the through air openings in the perimeter of the heat dissipating structure cooling the exterior surfaces of the heat dissipating structure and the electronic device housing.
