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. The ability to understand the impact that light has on plant growth and development will be fundamental to allow improved designs of LED lighting systems for greenhouse and growth chamber systems.
