Lighting system to control the circadian rhythm of agricultural products and associated methods

摘要

A lighting system comprising a light source, a controller operably coupled to the light source, and a timekeeping device operably coupled to the controller. The controller is configured to receive a selected action time associated with an agricultural product. The agricultural product includes an associated circadian rhythm defining an optimal action time range. 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. The controller is configured to operate the light source according to the lighting schedule.

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.
