PROBLEM TO BE SOLVED: To enable a lighting system to irradiate light of high luminance by appropriately selecting from light of a plurality of different wavelengths and improving light guide efficiency.SOLUTION: The lighting system 1 is provided with three or more light sources 10A, 10B, 10C, 10D, 10E, 10F arrayed with their light axes crossed at one point and emitting light of different wavelength ranges, an optical element 13 transmitting light from one light source and reflecting light from the others to let the light from the one light source into its light path, and an optical element rotating means 14 for rotating the optical element in an arraying direction of the light sources. |
