LIGHT EMITTING DEVICE AND ILLUMINATION DEVICE

A light-emitting device includes a wavelength conversion member including, in a dispersed manner, a first phosphor, a second phosphor, a third phosphor, a fourth phosphor, and a fifth phosphor, and a light emitter. The first phosphor has a peak in a wavelength region of 400 to 500 nm, the second pho...

description A light-emitting device includes a wavelength conversion member including, in a dispersed manner, a first phosphor, a second phosphor, a third phosphor, a fourth phosphor, and a fifth phosphor, and a light emitter. The first phosphor has a peak in a wavelength region of 400 to 500 nm, the second phosphor in 450 to 550 nm, the third phosphor in 500 to 600 nm, the fourth phosphor in 600 to 700 nm, and a fifth phosphor in 680 to 800 nm. The light emitter emits light in an ultraviolet region of 380 to 430 nm. The light-emitting device has an emission spectrum in a region of 380 to 950 nm including peaks in regions of 380 to 430 nm, 430 to 480 nm, 480 to 550 nm, 550 to 650 nm, and 650 to 750 nm, and differences between relative light intensities at the peaks are less than 20%.
