Abstract

A lighting apparatus includes a light emitter that emits a first illumination light as a display illumination light. The optical characteristics of the first illumination light are: a correlated color temperature in a range from 3800 K to 6500 K, inclusive; chromaticity deviation Duv in a range from −9 to 0, inclusive; and an intrinsic photosensitive retinal ganglion cell (ipRGC) stimulus level of at least 0.6, the ipRGC stimulus level being a value standardized by setting an ipRGC stimulus level of light emitted from a D65 light source to 1.
