LIGHTING EQUIPMENT, LIGHTING DEVICE, AND LIGHT-EMITTING MODULE

摘要

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.

1. Lighting equipment, comprising
a first white light source including a first light-emitting element and a first wavelength converter member performing wavelength conversion on a portion of light from the first light-emitting element, the first white light source producing first white light by combining light from the first light-emitting element that is converted by the first wavelength converter member and light from the first light-emitting element that is not converted by the first wavelength converter member; a second white light source including a second light-emitting element and a second wavelength converter member performing wavelength conversion on a portion of light from the second light-emitting element, the second white light source producing second white light by combining light from the second light-emitting element that is converted by the second wavelength converter member and light from the second light-emitting element that is not converted by the second wavelength converter member, the light from the second light-emitting element that is converted by the second wavelength converter member differing spectrally from the light from the first light-emitting element that is converted by the first wavelength converter member in terms of at least one of peak wavelength and full width at half maximum; a red light source including a red light-emitting element and producing red light; and a control circuit performing control of lighting the first light-emitting element while substantially not lighting the second light-emitting element when the red light-emitting element is lit under first lighting conditions where a peak wavelength of light from the red light-emitting element has a first value, and of lighting the second light-emitting element while substantially not lighting the first light-emitting element when the red light-emitting element is lit under second lighting conditions where the peak wavelength of the light from the red light-emitting element has a second value, the second value being greater than the first value.
