NOVEL LIGHT SOURCES AND METHODS FOR ILLUMINATING PLANTS TO ACHIEVE EFFECTIVE PLANT GROWTH
First Claim
1. A light source for growing a plant or a plant propagule, comprising:
- a power component requiring an amount of input power;
a light-emitting component receiving said input power from said power component for illuminating, for a period of time, a growth area of said plant or said plant propagule with an incident light having a spectral profile defined by a first set of wavelengths, a second set of wavelengths and a third set of wavelengths, said light-emitting component provides a photosynthetic productivity from said plant or plant propagule that is greater than that achieved if the same said growth area of said plant or said plant propagule had been illuminated by another incident light for substantially said period of time, and said another incident light includes said first set of wavelengths and third set of wavelengths, but does not include said second set of wavelengths; and
wherein said first set of wavelengths includes wavelengths that are between about 400 nm and about 470 nm, said second set of wavelengths includes wavelengths that are between about 526 nm and about 570 nm, and said third set of wavelengths includes wavelengths that are between about 626 nm and about 700 nm.

Abstract
A light source for growing a plant or its propagule is described. The light source includes: (i) a power component requiring an input power; (ii) a light source receiving the input power to illuminate, for a period of time, a growth area of the plant/propagule with an incident light having a spectral profile defined by a first (i.e., between about 400 nm and about 470 nm), a second (i.e., between about 526 nm and about 570 nm) and a third (i.e., between about 626 nm and about 700 nm) set of wavelengths, the light source component provides a photosynthetic productivity from the plant/propagule that is greater than that achieved if the same the growth area of the plant/propagule had been illuminated by another incident light for substantially same time period, and the another incident light includes the first and third, but not the second set of wavelengths.
