Abstract
A lighting device for growing a plant includes: not less than two sorts of semiconductor light-emitting element, each having a peak emission wavelength in a range of 380 nm to 500 nm, the not less than two sorts of semiconductor light-emitting element being different from each other in peak emission wavelength by not less than 5 nm; and a red fluorescent material which (i) is excited by light of at least one of the not less than two sorts of semiconductor light-emitting element and (ii) has a peak emission wavelength in a range of 600 nm to 780 nm.
