LIGHT SOURCE UNIT INCLUDING AN AREA OF LUMINESCENT MATERIAL EMITTING LUMINESCENT LIGHT IN GREEN WAVELENGTH RANGE ON PART OF MEMBER SITUATED ON OPTICAL PATH OF LIGHT IN BLUE WAVELENGTH RANGE AND PROJECTOR

摘要

A light source unit includes a solid light emitting element that emits light in the blue wavelength range, a luminous light emitting portion on which a luminescent material layer is laid out, the luminescent material layer using the light emitted from the solid light emitting element as excitation light to emit light in a wavelength range of which wavelengths are longer than a wavelength of the excitation light, and a light transmitting portion that transmits the light emitted from the solid light emitting element, and an area of a luminescent material that emits luminous light in the green wavelength range is provided at part of the light transmitting portion.
