Abstract
A light-emitting device that can implement a natural, vivid, highly visible and comfortable appearance of colors and appearance of objects as if the objects are seen outdoors is provided. The light-emitting device can change the appearance of colors of the illuminated objects so as to satisfy the requirements for various illuminations. Furthermore, the appearance of colors of the light-emitting device which currently exists or is in use, and which includes a semiconductor light-emitting device of which appearance of colors is not very good, is improved. A method for driving the light-emitting device, an illumination method by the device, and a method for manufacturing the light-emitting device are also provided. These features are achieved by the light-emitting device that incorporates light-emitting elements and satisfies predetermined requirements, in which φSSL(λ) emitted from the light-emitting device satisfies a predetermined condition.
