Lighting equipment, illumination device and light emitting module
Abstract:
Lighting equipment 1 is provided that enables illumination light having a stable FCI to be obtained, without influence from the lighting conditions. To this end, a lighting circuit 4 performs control of lighting a first red light source R1 and lighting a white light source W while not lighting or faintly lighting a second red light source R2 under first lighting conditions in which the first red light source R1 is expected to produce red light with a first peak wavelength, and of lighting the second red light source R2 and lighting the white light source W while not lighting or faintly lighting the first red light source R1 under second lighting conditions in which the first red light source R1 is expected to produce the red light with a second peak wavelength that is shifted toward a longer wavelength relative to the first peak wavelength.
