Light source unit and projector

Abstract

A light source unit having a luminescent material plate tight sealing construction with a dust-proof measure where a luminescent material plate is sealed tight from a circumference thereof by attaching tightly a luminescent material plate holding metallic plate to a collective lens and a projector having the light source unit are provided. The light source unit has an excitation light source device emitting excitation light and a luminous light emitting device, and the luminous light emitting device includes a luminescent material plate on to which excitation light from the excitation light source device is shone to emit luminous light of a different wavelength from the excitation light, a substrate on which the luminescent material plate is rested, a collective lens covering the luminescent material plate, and a lens holder holding the collective lens, whereby the luminescent material plate is sealed tight by at least the substrate and the collective lens.
