Abstract:
A wavelength conversion element includes a phosphor layer that emits fluorescence when excitation light is incident on the phosphor layer, a base having a reflection layer, and a filter provided on a side of the phosphor layer that is the side opposite the reflection layer. The filter is so configured that the reflectance of light that belongs to a wavelength region from the wavelength of the excitation light to the wavelength of the fluorescence and is incident on the filter at right angles is minimized at a first wavelength, and the first wavelength is located between the peak wavelength of the excitation light and the peak wavelength of the fluorescence.

Claim (Index 3):
A wavelength conversion element comprising:\n a phosphor layer that emits fluorescence when excitation light is incident on the phosphor layer; a base having a reflection layer; and a filter provided on a side of the phosphor layer that is a side opposite the reflection layer, wherein the filter transmits excitation light incident on the filter at right angles out of the excitation light and fluorescence incident on the filter at right angles out of the fluorescence and reflects fluorescence incident on the filter at a second angle of incidence out of the fluorescence in such a way that optical intensity of the reflected fluorescence is higher than optical intensity of transmitted fluorescence.
