A light emitting apparatus, comprising:
- a light source unit emitting a plurality of excitation light beams having linearity;
- a first reflection unit reflecting the excitation light beams incident thereon in an incident direction parallel to an axis of symmetry while having linearity and collecting the reflected excitation light beams on a focus position;
- a wavelength conversion unit disposed on the focus position for transmitting the excitation light beams reflected and collected by the first reflection unit;
- and
- a base substrate having the focus position and including a through hole into which the wavelength conversion unit is inserted.
