Integrated LED/Imaging Illumination Panels Demonstrated within a Small Plant Growth Chamber Project

Furthermore, these panels are commonly operated using high voltage AC power sources, which is not ideal in a potentially wet environment. Therefore, to address these issues, custom LED illumination panels were designed and developed for this project&rsquo;s plant growth chamber.</strong></p><p><strong>A systematic approach was taken to determine the general size, specifications, and shape of a portable plant growth unit.

Once the general size and shape were finalized, the detailed design of the support structure, aeroponics, and lighting subsystems were developed. Particular attention was given to heat transfer and the expected LED thermal environment.&nbsp; Additionally, a&nbsp;</strong><strong>computational analysis was performed to determine optimal LED nodes placement so that two different uniform illumination fields could be yielded:&nbsp; (1) for germinating plants, lower intensity light, and (2) for larger maturing plants, a brighter one.&nbsp; Also, aeroponic studies were reviewed to identify an efficient and user-friendly system that would require minimal user involvement.</strong></p>
