Horticultural light

Abstract

A horticultural lighting system and method for controlling same. Lights operating at different peak wavelengths, which affect the color of lights, can be optimized for different plant species during different stages of growth. The present disclosure pertains to a horticultural light, a system of horticultural lights, and a method for controlling light output to optimize different types of plants in various stages of plant growth cycles.

         4 . The horticultural light according to  claim 2 , wherein some of the red LEDs have a wavelength of 660 nm, and some of the red LEDs have a wavelength of 634 nm. 
     
     
         5 . The horticultural light according to  claim 2 , wherein each of the blue LEDs have a wavelength of 465 nm. 
     
     
         6 . The horticultural light according to  claim 2 , wherein each of the UV LEDs have a wavelength of 385 nm. 
     
     
         7 . The horticultural light according to  claim 2 , wherein each of the white LEDs are 5000 k. 
     
     
         8 . The horticultural light according to  claim 1 , further comprising a current measuring device in electrical communication with at least one LED color group, the current measuring device detecting current flow to the LED color group. 
     
     
         9 . The horticultural light according to  claim 8 , wherein the current measuring device detects a zero current or current fault. 
     
     
         10 . A system of horticultural lights comprising:
 a plurality of horticultural lights, each consisting a housing fixture and an array of different colored light emitting diodes (LEDs);   a plurality of current control channels in electrical communication with at least one of the LEDs;   a plurality of fixture controls for controlling light wave intensity of each LED via the current control channel;   a fixture mesh network including at least one fixture control;   an at least one master fixture control for receiving information from a user and relaying the information to other fixture control(s) in the fixture mesh network; and   a plurality of fixture firmware consisting one or more zone control variable, the one or more user input recipe, and multiple preset modes of operation.   
     
     
         11 . The system of horticultural lights according to  claim 10 , further comprising a plurality of current measuring devices, each of the current measuring devices in electrical communication with at least one LED color group and detecting current flow to the LED color group. 
     
     
         12 . The horticultural light according to  claim 11 , wherein each of the current measuring devices detects a zero current or current fault. 
     
     
         13 . A method of programming a horticultural light comprising:
 receiving a user input including intensity level for at least one LED color group;   transmitting the user input to a fixture control;   relaying information between a network of at least one fixture controls; and   based on the relayed information, controlling a wavelength intensity of a light emitting diode (LED) to produce a desirable colored light.   
     
     
         14 . The method of programming the horticultural light according to  claim 13 , wherein the fixture control can be updated via a wireless interface. 
     
     
         15 . The method of programming the horticultural light according to  claim 14 , wherein a master fixture control can receive the recipe via a wireless interface and transmit the information to other fixture control(s) in a fixture mesh network. 
     
     
         16 . The method of programming the horticultural light according to  claim 14  wherein a fixture firmware can be updated by connecting to an electrical control device via a USB bridge node, including a USB port and antenna. 
     
     
         17 . The method of programming the horticultural light according to  claim 13 , further comprising measuring a current flow in at least one LED color group. 
     
     
         18 . The method of programming the horticultural light according to  claim 17 , wherein the measuring step includes detecting zero current or a current fault.
