| abstract | PROBLEM TO BE SOLVED: To provide a light emitting device in consideration of circadian rhythm and color rendering. SOLUTION: The present invention includes one or a plurality of light emitting elements and a plurality of phosphors, and the first light, the second light, and the second light by the one or a plurality of light emitting elements and the one or a plurality of phosphors. A light emitting device that emits light of 3, the first light has a correlated color temperature of 1500 K or more and 3500 K or less, and the value of the color development evaluation number R9 is 50 or more, and the second light is correlated. The color temperature is 3500K or more and 5500K or less, the value of the color performance evaluation number R9 is 50 or more, and the third light has the X-coordinate and Y-coordinate values in the chromaticity diagram of the CIE1931 color system as black bodies. It is smaller than the X-coordinate and Y-coordinate values at a color temperature of 5500K on the radiation trajectory. Further, in light having a correlated color temperature of 6500 K, the value of the color rendering index R9 is 50 or more, and the value of the melanopic ratio is 1.0 or more.
