More Information
Summary:A light-emitting device (10) is provided with a solid-state light-emitting element (3) and a phosphor, and emits output light (4). The spectral distribution of the output light has a first light component (5) and a second light component (6) derived from the fluorescent light emitted by the phosphor, and has a first minimum value (8) between the first light component and the second light component. The first light component is a fluorescent component having an intensity maximum value in a wavelength range of 560 nm or more and less than 700 nm. The second light component is a fluorescent component having an intensity maximum value in a wavelength range of 700 nm or more and less than 2500 nm. An intensity maximum value of the second light component is greater than an intensity maximum value of the first light component. The first minimum value is less than 50% of an intensity maximum value of the second light component. The electronic device is provided with the light-emitting device. 发光装置(10)具备固体发光元件(3)和荧光体，
