Abstract
An optical component includes a phosphor member, an optical filter arranged over the phosphor member at a light extraction side of the phosphor member, and a light scattering member arranged on over the optical filter. An excitation spectrum of the phosphor member has a first local maximum wavelength in the visible region and a second local maximum wavelength in the ultraviolet region. The optical filter is configured to reflect a portion of light at the first local maximum wavelength and a portion or all of light at the second local maximum wavelength.
