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 equipment 1 performs control of lighting a first light-emitting element 12a while substantially not lighting a second light-emitting element 12b when a red light-emitting element 12c is lit under first lighting conditions where a peak wavelength of light from the red light-emitting element 12c has a first value, and of lighting the second light-emitting element 12b while substantially not lighting the first light-emitting element 12a when the red light-emitting element 12c is lit under second lighting conditions where the peak wavelength of the light from the red light-emitting element 12c has a second value, the second value being greater than the first value.
