Abstract
Spatial distributions of photosynthetic photon flux density (PPFD) in the cultivation space of a plant factory with light-emitting diodes (LEDs) are simulated using the free software package DIALux under different design conditions including (1) reflectance of cultivation panel surfaces, (2) width of side reflectors, (3) layout of LED tubes on the ceiling, (4) angular light distribution of LED lamp, and (5) height of the plant canopy. The simulation shows that the average and uniformity of PPFD above the cultivation panels and percent loss of photosynthetic photons to the outside of the cultivation space are affected not only by the characteristics of LED tubes but also by those of the cultivation space.
