| 摘要 |
A projection apparatus includes a fluorescence plate including a fluorescence layer configured to emit fluorescence light beams upon irradiation of the excitation lights, a first lens array, provided on a light source side of the fluorescence plate and including a plurality of lenses arranged in an array to correspond with the light-emitting elements, and configured to collect the fluorescence light beams and emit the fluorescence light beams to be parallel with one another, and a projection unit configured to form an optical image using the fluorescence light beams obtained via the first lens array and project the optical image on a projection object.
