Abstract
An LED lighting sheet () for animal/plant growth includes an array of LED chips (). At any location 50 mm away from the LED chips () in a lower region below the LED lighting sheet () for animal/plant growth, a photosynthetic photon flux density converted by input power and normalized by an average value over the lower region is greater than or equal to 0.2. A variation in photosynthetic photon flux densities respectively measured at locations 50 mm away from the LED chips () in the lower region below the LED lighting sheet () for animal/plant growth is less than or equal to 0.5 in standard deviation when normalized by the average value.
