Abstract

The systems and methods disclosed herein include an apparatus that includes a user interface configured to receive user input, and a photoperiod controller configured to calculate a photoperiod schedule for one or more plants based on the user input and generate control signals that adjust light output of at least one luminaire to implement the photoperiod schedule.

First claim

What is claimed is:

1. An apparatus, comprising:
a user interface configured to receive user input, the user input including at least a crop identifier indicating at least one of a plant genus, species, variety, and cultivar; and
a photoperiod controller configured to:
calculate a photoperiod schedule for one or more plants based on the user input, wherein the photoperiod schedule comprises a plurality of time periods and/or growth stages for the one or more plants, and a photoperiod duration for each of said time periods and/or the growth stages;
adjust the photoperiod schedule based on additional user input, the additional user input including at least one of climate parameters, duration of a growth stage, duration of a photoperiod cycle, and one or more time periods with corresponding irradiance deltas;
generate control signals that adjust light output of at least one luminaire to implement the photoperiod schedule; and
transmit the control signals to the at least one luminaire via a communications gateway connected to the photoperiod controller, the communications gateway communicatively coupled to a plurality of luminaires over a network.

2. The apparatus of claim 1 , wherein the additional user input is said climate parameters.

3. The apparatus of claim 1 , wherein the photoperiod controller is further configured to adjust the photoperiod schedule based on further input from at least one sensor.

4. The apparatus of claim 3 , wherein the photoperiod controller is further configured to dynamically adjust the photoperiod schedule during implementation of the photoperiod schedule based on the further input.

5. The apparatus of claim 1 , wherein the photoperiod schedule further comprises PPFD (photosynthetic photon flux density) values for each of the plurality of time periods.

6. The apparatus of claim 1 , wherein the photoperiod controller is further configured to:
transmit the user input to a server; and
receive the photoperiod schedule from the server, wherein the server calculates the photoperiod schedule.

7. A method, comprising:
receiving, via a user interface of a controller, user input, the user input including at least a crop identifier indicating at least one of a plant genus, species, variety, and cultivar, for generating a photoperiod schedule for one or more plants;
calculating the photoperiod schedule based on the user input, wherein the photoperiod schedule comprises a plurality of time periods and/or growth stages for the one or more plants, and a photoperiod duration for each of said time periods and/or the growth stages;
adjusting the photoperiod schedule based on additional user input, the additional user input including at least one of climate parameters, duration of a growth stage, duration of a photoperiod cycle, and one or more time periods with corresponding irradiance;
generating control signals that adjust light output of at least one luminaire to implement the photoperiod schedule; and
transmitting the control signals to the at least one luminaire via a communications gateway connected to the controller, the communications gateway communicatively coupled to a plurality of luminaires over a network.

8. The method of claim 7 , wherein the additional user input is said climate parameters.

9. The method of claim 7 , further comprising:
adjusting the photoperiod schedule based on further input from at least one of a user and a sensor.

10. The method of claim 9 , wherein adjusting the photoperiod schedule comprises dynamically adjusting the photoperiod schedule during implementation of the photoperiod schedule based on the further input.

11. The method of claim 7 , wherein the photoperiod schedule further comprises PPFD (photosynthetic photon flux density) values for each of the plurality of time periods.

12. The method of claim 7 , further comprising:
transmitting the control signals to the at least one luminaire; and
adjusting, by the at least one luminaire, the light output of the at least one luminaire according to the photoperiod schedule.

13. The method of claim 7 , wherein:
the controller transmits the user input to a server;
the server calculates the photoperiod schedule and transmits the photoperiod schedule to the controller; and
the controller generates the control signals based on the photoperiod schedule.

14. A system, comprising:
a photoperiod controller configured to generate control signals based on a photoperiod schedule and transmit the control signals to at least one luminaire via a communications gateway connected to the photoperiod controller, the communications gateway communicatively coupled to a plurality of luminaires over a communications network;
a user interface configured to receive a user input and an additional user input to the photoperiod controller, the photoperiod schedule based on the user input and the additional user input, wherein the photoperiod schedule comprises a plurality of time periods and/or growth stages for one or more plants, and a photoperiod duration for each of said time periods and/or the growth stages, the user input including at least a crop identifier indicating at least one of a plant genus, species, variety, and cultivar;
the plurality of luminaires configured to emit light suitable for photosynthesis in plants at a plurality of different selectable levels of light output; and
the communications network via which the control signals are provided to the plurality of luminaires, the plurality of luminaires adjusting the light output in response to the control signals.

15. The system of claim 14 , wherein the photoperiod controller is further configured to adjust the photoperiod schedule based on further input from at least one of a user and a sensor.

16. The system of claim 14 , further comprising a server communicatively coupled to the photoperiod controller via the communications network, wherein:
the photoperiod controller is further configured to transmit the user input and the additional user input to the server and receive the photoperiod schedule from the server; and
the server is configured to calculate the photoperiod schedule based on the user input.

17. The system of claim 16 , wherein the server is further configured to adjust the photoperiod schedule based on further input from at least one of a user and a sensor.
