Wavelength conversion component having photo-luminescence material embedded into a hermetic material for remote wavelength conversion

摘要

Disclosed are improved wavelength conversion components having photo-luminescent materials embedded into a hermetic material. Phosphor materials are embedded into a layer of glass, which is then utilized in a remote phosphor LED lighting apparatus. Methods for manufacturing these advanced wavelength conversion components are also described.

1. A wavelength conversion component embodied in a light emitting device, comprising:
an amorphous hermetic layer that is optically transparent to wavelengths of the range of 400 nm to 700 nm; a light-transmissive substrate layer, wherein the substrate layer and the amorphous hermetic layer are in direct contact a photo-luminescent material embedded within the amorphous hermetic layer, comprising a phosphor operable to emit light of a first wavelength range when excited by excitation light of a second wavelength range; and wherein light of the first wavelength range has a longer wavelength than light of the second wavelength range; at least one solid-state light emitter operable to generate excitation light, wherein the at least one solid-state light emitter is spaced apart from the amorphous hermetic layer by an air gap.
