| Abstract: |
Disclosed are a method and an apparatus for irradiation of plants using optoelectronic devices. In accordance with this invention, optoelectronic devices that emit radiant energy at the appropriate wavelength are operated in a continuous mode or pulsed asymmetrically at a frequency and level of electrical power that results in sufficient irradiance to support plant growth and development. The apparatus consists of: (1) an array of optoelectronic devices, primarily light emitting diodes, for producing irradiance in each of three different wavelength regions necessary for specific plant photobiological reactions, (2) a pulse generator and associated electric power driving components, and (3) an electric direct current (D.C.) power supply.

We claim:
1. A method for providing radiant energy to support plant growth and development comprising the step of:
- exposing a plant to radiant energy provided by an array of light emitting diodes having a maximum spectral emission that matches the maximum absorption of chlorophyll and meets the photomorphogenic and phototropic requirements of a plant at a sufficient intensity and duration to drive photosynthesis at a rate sufficient to support plant growth and development from germination to maturity.
