The environmental detection system includes one or more sensors operable to detect a parameter associated with a space in which the lighting fixture is located.

Abstract: A method for controlling operation of a lighting system is provided. The method includes operating the lighting system in a first mode during a time period to provide a first light output. The first output can be a blend of HINS light and non-HINS light. The method includes determining a dosage amount of HINS light provided during the time period. Furthermore, the method includes operating the lighting system in a second mode to provide a second lighting output. The second light output can be HINS light or a blend of HINS light and non-HINS light. Furthermore, spectral energy associated with HINS light in the second light output is greater than spectral energy associated with the HINS light in the first light output.

Abstract: A bladeless ceiling fan is provided. The bladeless ceiling fan includes a housing configured to accommodate an electric motor. The housing can define one or more vents through which air enters an interior of the housing. The bladeless ceiling fan can further include an airfoil defining an interior passage. In addition, the bladeless ceiling fan includes one or more conduits. The one or more conduits extend from the housing to the airfoil such that air within the interior of the housing flows through the one or more conduits and into the interior passage defined by the airfoil.

Abstract: A method for controlling operation of a lighting system is provided. The method includes operating the lighting system in a first mode during a time period to provide a first light output. The first output can be a blend of HINS light and non-HINS light. The method includes determining a dosage amount of HINS light provided during the time period. Furthermore, the method includes operating the lighting system in a second mode to provide a second lighting output. The second light output can be HINS light or a blend of HINS light and non-HINS light. Furthermore, spectral energy associated with HINS light in the second light output is greater than spectral energy associated with the HINS light in the first light output.
