PROBLEM TO BE SOLVED: To provide a low-cost mixed lighting system easy to manufacture. SOLUTION: This mixed lighting system 1 installed on the front side of a mirror body M is so structured that two light sources 2 and 3 are installed inside on the front side and on the back side, respectively; and a shading plate 4 is installed between them. The light sources 2 and 3 having color temperatures different from each other are used; a light ray emitted from the front-side light source 2 is used as direct illumination lightα; a light ray emitted from the back-side light source 3 is reflected by the mirror body M and thereafter used as indirect illumination lightβreaching an illumination area. The direct illumination lightαand the indirect illumination lightβrespectively emitted from the two light sources 2 and 3 having the different color temperatures are mixed in the illumination area to form illumination of an intermediate color temperature between both of them. Since color mixture of the direct illumination lightαwith the indirect illumination lightβis not generated, color irregularity is reduced and color rendering properties can be enhanced. By installing a switch capable of individually operating lighting and extinction of the two light sources 2 and 3, three kinds of color temperatures such as high and low color temperatures, and an intermediate color temperature between them can be changed over to one another as desired.
