Fluid-cooled led-based lighting methods and apparatus for controlled environment agriculture with integrated cameras and/or sensors and wireless communications

A fluid-cooled LED-based lighting fixture, comprising:

• an extruded aluminum frame including at least a first channel formed therein, a second channel formed therein, and at least one enclosed cavity formed therein, the extruded aluminum frame further including a fin protruding from the frame and having a plurality of holes to facilitate mechanical coupling of the lighting fixture to at least one support structure;
• at least one LED light source mechanically supported by the extruded aluminum frame;
• a first copper pipe to carry a fluid coolant to extract heat generated by at least the at least one LED light source during operation of the lighting fixture, wherein the first copper pipe is press-fit into the first channel of the extruded aluminum frame so as to establish a first thermal connection between the first copper pipe and the extruded aluminum frame;
• a second copper pipe to carry the fluid coolant, wherein the second copper pipe is press-fit into the second channel of the extruded aluminum frame so as to establish a second thermal connection between the second copper pipe and the extruded aluminum frame;
• control circuity, disposed in the at least one enclosed cavity of the extruded aluminum frame, to receive AC power and to control the at least one LED light source;
• at least one camera disposed in or on the extruded aluminum frame;
• and
• a plurality of ports, electrically coupled to at least some of the control circuitry, to provide DC power to at least one auxiliary device coupled to at least one of the plurality of ports.
