Abstract:
A light emitting apparatus includes a first rod integrator and a second rod integrator supported by a support substrate and a light emitting device disposed between the first rod integrator and the second rod integrator. The light emitting device emits a plurality of light beams to be incident on the first rod integrator and a plurality of light beams to be incident on the second rod integrator. Each of the rod integrators has a light incident surface on which the plurality of light beams are incident, a bent portion that changes the propagating direction of the plurality of incident light beams, and a light exiting surface through which the plurality of light beams mixed with each other exit.
