using wavelength conversion means distinct or spaced from the light-generating element, e.g. a remote phosphor layer

Full Title

Light sources using semiconductor devices as light-generating elements, e.g. using light-emitting diodes [LED] or lasers > Optical arrangements integrated in the light source, e.g. for improving the colour rendering index or the light extraction > using wavelength conversion means distinct or spaced from the light-generating element, e.g. a remote phosphor layer
