ABSTRACT:
An illumination apparatus includes a transparent substrate, a phosphor layer, an optical wavelength selection filter layer, and a light-emitting device. The transparent substrate includes a first surface and a second surface opposing each other. The phosphor layer is disposed on the first surface side of the transparent substrate. The optical wavelength selection filter layer is disposed on the second surface side of the transparent substrate and configured to transmit light of a first wavelength therethrough and reflect light of a second wavelength that is emitted from the phosphor layer by being excited by the light of the first wavelength. The light-emitting device is configured to emit the light of the first wavelength from the optical wavelength selection filter layer side thereof toward the optical wavelength selection filter layer.
