Abstract

Lighting equipment is provided that enables illumination light having a stable FCI to be obtained, without influence from the lighting conditions. To this end, lighting equipmentperforms control of lighting a first light-emitting elementwhile substantially not lighting a second light-emitting elementwhen a red light-emitting elementis lit under first lighting conditions where a peak wavelength of light from the red light-emitting elementhas a first value, and of lighting the second light-emitting elementwhile substantially not lighting the first light-emitting elementwhen the red light-emitting elementis lit under second lighting conditions where the peak wavelength of the light from the red light-emitting elementhas a second value, the second value being greater than the first value.
