Abstract
The present invention provides a semiconductor light-emitting device which emits light with high chroma, and an exhibit-irradiating illumination device, a meat-irradiating illumination device, a vegetable-irradiating illumination device, a fresh fish-irradiating illumination device, a general-purpose illumination device, and a semiconductor light-emitting system which include the semiconductor light-emitting device. A semiconductor light-emitting devicecomprises an LED chipas a semiconductor light-emitting element and a phosphorwhich uses the LED chipas an excitation source to emit light. The phosphor contains at least a green phosphor and a red phosphor, and a value of intensity of light with a wavelength of 660 nm in a spectrum of beam-normalized light emitted from the semiconductor light-emitting deviceis 170% or more and 300% or less of a value of intensity of light with a wavelength of 660 nm in a spectrum of beam-normalized reference light for color rendering evaluation.
