PROBLEM TO BE SOLVED: To improve the light source efficiency of a "light-emitting device capable of causing colors and objects to assume a natural, vivid, highly visible, and pleasant appearance," by making the spectral distribution completely different from conventional spectral distributions while excellent characteristics in terms of appearance of colors are maintained.SOLUTION: A light-emitting device having at least, as light-emitting elements, a blue semiconductor light-emitting element, a green phosphor, and a red phosphor is characterized in that light emitted from the light-emitting device in the main radiation direction satisfies all specific conditions. |
