PROBLEM TO BE SOLVED: To provide a photosynthesis unit capable of easily changing the synthesis of a plurality of bunches of laser beams.SOLUTION: A photosynthesis unit according to the present invention is configured so that lenses L1, L2, L3, L4, and Lo, a color wheel 120, a motor 130, mirrors M, dichroic mirrors DM are disposed within a housing 110. First to fourth bunches of laser beams Lb1, Lb2, Lb3, and Lb4 in a blue band are input to the housing 110 from one surface thereof and converged onto the color wheel 120 by the lenses L1, L2, L3, and L4 of a shift optical system. R light, G light, B light, and Y light emitted from the color wheel 120 are synthesized by the lens Lo and resultant light is output. |
