An illuminating apparatus is adapted to supply input light to a light-processing unit of a projection display, and includes a lighting unit, a lens unit and a light integrator. The lighting unit includes a plurality of lamp bases, each of which is operable so as to generate forwardly directed light rays. The lens unit is adapted to be disposed between the lighting unit and the light-processing unit so as to receive the forwardly directed light rays from the lamp bases. The light integrator has an input side facing the lens unit so as to receive the light rays that pass through the lens unit, and an output side adapted to face the light-processing unit. The light rays that are received from the lens unit are radiated by the light integrator as an evenly distributed light source at the output side for reception by the light-processing unit.
