摘要：
A substrate-type LED light source (10) includes: at least one blue LED chip (2) which has an emission peak in a range from 400 nm to 480 nm so as to correspond to a blue light region absorption peak of chlorophyll; a red phosphor (7b) which emit, upon receiving excitation light from the at least one blue LED chip (2), light having a peak wavelength in a range from 620 nm to 700 nm so as to correspond to a red light region absorption peak of chlorophyll; and a resin layer (7) in which the red phosphor 7b is dispersed and which covers the at least one blue LED chip (2).
