<p>To radiate light having higher luminance by selecting light having a plurality of different wavelengths as needed, and by improving light guide efficiency. Provided is an illuminating apparatus (1), which is provided with: three or more light sources (10A, 10B, 10C, 10D, 10E, 10F), which are disposed with optical axes thereof intersecting at one point, and which output light in different wavelength regions; an optical element (13), which passes through light emitted from one light source among the light sources, reflects light emitted from other light sources, and makes the light enter an optical path of the light emitted from the one light source; and an optical element rotating means (14), which rotates the optical element in the direction in which the light sources are disposed.</p> |
