Abstract
A wavelength conversion component for remote wavelength conversion is described in which a wavelength conversion layer is sandwiched between two light transmissive hermetic substrates. The light transmissive hermetic substrates form a barrier that protects the wavelength conversion layer from exposure to external environmental conditions. In some approaches, the wavelength conversion component further includes a sealant material disposed around an outer edge of the sandwich structure, where the sealant material hermetically seals an outer edge wavelength conversion layer.
