A lighting fixture includes a frame, one or more LED light sources to emit radiation, control circuitry to receive AC power and control the one or more LED light sources, and a coolant pipe to carry a fluid coolant. The lighting fixture further includes a tube and end caps that together form an enclosed cavity to contain the frame, the LED light sources, and the control circuitry. In example implementations, the tube does not physically contact the frame, the LED light sources, and the control circuitry. The cavity may further contain air, gas, or vacuum that forms a thermal barrier between the tube and the LED light sources to reduce heat dissipation from the LED light sources to the environment. The tube may further enable the lighting fixture to be rotatably and/or translationally adjustable relative to a support structure after installation in a close proximity grow system.

A cooling system for a light emitting diode assembly includes a heat exchanger configured to exchange heat from a fluid to ambient air, an enclosure configured to house the LED assembly, and a pump configured to circulate the fluid through the enclosure, through the LED assembly, or both, and through the heat exchanger. The fluid is configured to absorb heat at the LED assembly and generated by the LED assembly, and the heat exchanger is configured to cool the fluid and remove the heat absorbed by the fluid at the LED assembly.

An integrated sensor assembly provides multiple sensing modalities to monitor an agricultural environment, and may be employed in or used with controlled environment agriculture (CEA) systems to control and maintain improved growth conditions for various plants. In one exemplary implementation, an integrated sensor assembly includes sensors to monitor parameters important to plant growth, such as a natural light sensor, an air temperature sensor, a relative humidity sensor, an air flow sensor, a carbon dioxide (CO2) sensor, and a remote infrared (IR) temperature sensor. The sensors are mounted onto a single circuit board, which is then placed inside a housing for protection from the ambient environment. The housing can include one or more openings and apertures to facilitate sensing with protective covers where appropriate. A USB port can be included to supply electrical power and transfer of data to and from the integrated sensor assembly (e.g., to provide plug-and-play functionality).
