Abstract:
A lighting device includes a white LED, a full-color LED, and a reflecting portion. The reflecting portion reflects light from the white LED and the full-color LED. A microcomputer turns on the full-color LED to emit light containing a red light component while the white LED is on. Further, the white LED and the full-color LED are arranged so that reflected lights thereof reflected by the reflecting portion are mixed to perform illumination. Thereby, direct lights of the white LED and the full-color LED cannot be visually recognized. Further, light from the white LED with a lot of blue components is compensated with light containing a red component from the full-color LED, and spectral distribution can be made even and illumination close to that of natural light can be performed.
