Abstract:
1. A lighting system comprising: a light source; a controller operably coupled to the light source; and a timekeeping device operably coupled to the controller; wherein the controller is configured to receive a selected action time associated with an agricultural product; wherein the agricultural product includes an associated circadian rhythm defining an optimal action time range; wherein the controller is configured to determine a lighting schedule responsive to the selected action time, the optimal action time range, and a time of day indicated by the timekeeping device, the lighting schedule being configured to impose a circadian rhythm on the agricultural product to shift the optimal action time range such that the selected action time coincides with the optimal action time range; wherein the controller is configured to operate the light source according to the lighting schedule; and wherein the controller is configured to determine a phase of the circadian rhythm of the agricultural product; wherein the controller is configured to determine a shifting schedule configured to shift the circadian rhythm of the agricultural product from the determined phase such that the optimal action time range corresponds with the selected action time.
