Maximizing Plant Production using Light Emitting Diode Arrays

This proposal is for the development and optimization of light emitting diodes (LEDs) for plant

growth. The development of LEDs over the complete range (and beyond) of photosynthetically active

radiation (PAR: 400 – 700nm) now allows focused research into the effect of wavelength on specific

plant responses. The LEDs produce light in a narrow spectrum (+/- 10nm) at intensities approaching

full sunlight. This project consists of characterizing LED arrays developed by our organization

sponsor and other sources to determine the arrays light intensity, spectral quality, energy usage, and

lifespan which will be used to optimize the design of future LED systems. These arrays will be used to

grow plants under both greenhouse and growth chamber conditions (primary lighting and intercanopy

lighting) to maximize production. LEDs have the potential to maximum plant production with reduced

energy costs over existing lighting systems…
