The LED grow-light system includes one or more grow-light canopies with linear LED light bars to provide upward and downward lighting in a central illumination area. The LED light bars are preferably configured to move up and down relative to a grow bed. The LED grow-light system or grow-light canopies constructed using T-slot interconnects that lock into T-channels of the T-slot bars and/or T-slot light bars. ## Claims ### Claim 1 A grow-light system comprising: a) a light canopy with T-slot bars and T-slot light bars for providing lighting into a central illumination area; and b) T-slot interconnects for securing the T-slot bars and T-slot light bars together to form the light canopy, the T-slot interconnects comprising body portions and two orthogonally elongated interlock tabs positioned on opposed sides of the body portions for placing into T-channels of the T-slot bars and/or T-slot light bars, wherein rotating the body portion secures the elongated interlock tabs within the T-channels and securing the T-slot bars and/or T-slot light bars together through the interconnect. ### Claim 2 (depends on 1) The grow-light system of claim 1, wherein the light canopy moves up and down to modulate the central illumination area. ### Claim 3 (depends on 1) The grow-light system of claim 1, wherein LEDs within the T-slot light bars are spatially modulated. ### Claim 4 (depends on 1) The grow-light system of claim 1, wherein separations between a portion of the T-slot light bars are spatially modulated. ### Claim 5 (depends on 2) The grow-light system of claim 2, further comprising stepper motors for automatically moving the light canopy up and down. ### Claim 6 (depends on 5) The grow-light system of claim 5, further comprising a control module for automatically controlling the stepper motors in response to control commands. ### Claim 7 (depends on 6) The grow-light system of claim 6, further comprising sensors for providing environmental data to the control module, wherein the environmental data is used to generate the control commands. ### Claim 8 A grow-light system comprising: a) a light canopy with T-slot bars and T-slot light bars for providing downward lighting into a central illumination area wherein the light canopy moves up and down relative to a grow bed; and b) T-slot interconnects for securing to the T-slot bars and/or a T-slot light bars, the T-slot interconnects comprising body portions and at least one elongated interlock tab positioned one side of the body portions for placing into a T-channel of the T-slot bars and/or T-slot light bars, wherein rotating the body portions secures the T-slot interconnects to the T-slot bars and/or the T-slot light bars. ### Claim 9 (depends on 8) The grow-light system of claim 8, wherein separations between a portion T-slot light bars are adjustable. ### Claim 10 (depends on 8) The grow-light system of claim 8, wherein LEDs within the T-slot light bars are spatially modulated to provide greater light output near ends of the T-slot light bars. ### Claim 11 (depends on 8) The grow-light system of claim 8, further comprising stepper motors for automatically moving the light canopy up and down. ### Claim 12 (depends on 11) The grow-light system of claim 11, further comprising a control module for automatically controlling the stepper motors in response to control commands. ### Claim 13 (depends on 12) The grow-light system of claim 12, further comprising sensors for providing environmental data to the control module, wherein the environmental data is used to generate the control commands. ### Claim 14 A grow-light system comprising: a) light canopies with T-slot bars and T-slot light bars for providing lighting into a central illumination area; and b) T-slot interconnects, wherein the T-slot bars and T-slot light bars of the light canopies are secured together through the T-slot interconnects comprising body portions and two orthogonally elongated interlock tabs positioned on opposed sides of the body portions for placing into T-channels of the T-slot bars and T-slot light bars, wherein rotating the body portions secure the T-slot interconnects to the T-slot bars and/or the T-slot light bars and wherein the light canopies move relative to each other. ### Claim 15 (depends on 14) The LED grow-light system of claim 14, further comprising a control module for receiving control commands. ### Claim 16 (depends on 15) The LED grow-light system of claim 15, wherein the control module includes a micro-processor for executing a grow-light protocol or program and controlling light emitted from the light canopies in accordance with the grow-light protocol or program. ### Claim 17 (depends on 14) The grow-light system of claim 14, wherein LEDs within a portion of the light bars are spatially modulated. ### Claim 18 (depends on 14) The grow-light system of claim 14, wherein separations between a portion of the light bars are spatially modulated. ### Claim 19 (depends on 14) The grow-light system of claim 14, further comprising stepper motors for automatically moving the light canopies in response to control commands. ### Claim 20 (depends on 19) The grow-light system of claim 19, further comprising sensors for providing environmental data to the control module, wherein the environmental data is used to generate the control commands.
