LIGHT SOURCES ADAPTED TO SPECTRAL SENSITIVITY OF PLANT

摘要

A method of stimulating plant growth in a controlled environment that includes providing a lighting assembly having a network of lighting elements such as light emitting diodes (LEDs) that provide light at a color tailored for an individual plant. The lighting assembly is positioned adjacent a plant such that the light produced is received by the plant. The lighting assembly additionally has a control assembly that includes driving circuitry that modulates the lighting elements to controllably provide predetermined periods of light and dark to stimulate continuous growth of the plant.

1. A method of stimulating plant growth in a controlled environment steps comprising:
providing a pair of input terminals that are adapted to receive a periodic excitation voltage such that the terminals receive a current of equal magnitude and opposite polarity, said current flowing in response to the excitation voltage to provide an AC input; providing a lighting assembly that has driving circuitry that receives the AC input and conditions the current; providing a network of lighting elements that produce light at a predetermined wavelength in response to the conditioned current; positioning the lighting assembly adjacent a plant such that the light produced is received by the plant; and modulating the conditioned current of the lighting elements with a control assembly to controllably provide predetermined periods of light and dark to stimulate continuous growth of the plant.
