SOLID LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a solid lighting device having a high color rendering property while maintaining efficiency.SOLUTION: A solid lighting device comprises: a first solid light emitting element for emitting first light having a first light emission spectrum whose width is smaller than 5 nm in a visible light wavelength; a second solid light emitting element for emitting second light having a second light emission spectrum whose width is smaller than 5 nm and having a peak wavelength longer than peak length of the first light by 5 nm or more in the visible light wavelength; and plural first wavelength complementing light emitting elements for respectively emitting light having a light emission spectrum whose width is smaller than 5 nm. A third light emission spectrum of third light that is collection of the light from the first wavelength complementing light emitting elements complements a region between the first light emission spectrum and the second light emission spectrum.
