PURPOSE:To reduce the problem of the heat generated from light source sections and thin the apparatus by arranging a light source mainly for direct illumination below an apparatus main body, and arranging light sources for indirect illumination at the same level on an outer periphery section. CONSTITUTION:The first illumination section 5 arranged with a light source mainly for direction illumination below an apparatus main body 1 and the second illumination section 8 formed with a through-shaped outer periphery frame 6 to surround the outer periphery of the first illumination section 5 and arranged with light sources mainly for indirect illumination in the outer periphery frame 6 are provided. The light source for direct illumination and the light sources for indirect illumination are arranged at the same level on nearly the same plane not to be overlapped together. The heat problem is reduced with a thin illumination apparatus, direct illumination and indirect illumination can be obtained independently or concurrently, indirect illumination with wide-range expansion is obtained, and effective illumination can be staged. |
