Abstract
Disclosed herein is an apparatus and method for providing light to grow a plant. An LED array comprises blue light in a band between about 350 nm and 550 nm, red light in a band at about 630 nm and dark red light in a band at about 660 nm. An input device is provided for interrupting the dark red band at 660 nm in order to continue to provide light the plant while the plant continues to flower.
Claims20
Apparatus for providing light to grow is plant, comprising:
- an LED array for emitting blue light between about 350 nm and 500 nm, red light at about 630 nm and red light at about 660 nm;
- an input device for producing a 660_nm_ON command and a 660_nm_OFF command;
- a controller in communication with said LED array and said input device, said controller responding to:
- (1) the 660_nm_ON command by causing said array to emit blue light between about 350 nm and 500 nm, red light at about 630 nm and red light at about 660 nm, and (2) the 660_nm_OFF command by causing said array to emit blue light between about 350 nm and 500 nm and red light at about 630 nm.

A grow light, comprising:
- an LED array for emitting blue light at a band between about 350 nm and 500 nm, red light at a band at about 630 nm and red light at a band at about 660 nm;
- at least one input device for selectively controlling the intensity of at least one light band;
- and
- a controller in communication with said LED array and said input device, said controller responding to a signal from said input device to command said array to change from a first state where said array emits light comprising a 660 nm band to a second state where said array emits light that does not comprise a 660 nm band.

A method of providing light to a plant, comprising:
- providing an LED array adapted to emit blue light at a band between about 350 nm and 500 nm, red light at band at about 630 nm and red light at a band at about 660 nm;
- conducting electrical power to the LED array to emit blue light at a band between about 350 nm and 500 nm, red light at band at about 630 nm and red light at a band at about 660 nm;
- and
- interrupting electrical power to the LEDs adapted to emit a 660 nm band within the LED array.
