Abstract
Light emitting diodes, components, and related methods, with improved performance over existing light emitting diodes. In some embodiments, light emitter devices included herein include a submount, a light emitter, a light affecting material, and a wavelength conversion component. Wavelength conversion components provided herein include a transparent substrate having an upper surface and a lower surface, and a phosphor compound disposed on the upper surface or lower surface, wherein the wavelength conversion component is configured to alter a wavelength of a light emitted from a light source when positioned proximate to the light source.
Claims20
A light emitter device comprising:
- a submount comprising an upper surface and a bottom surface;
- a first light emitter and a second light emitter disposed on the upper surface of the submount;
- a light affecting material disposed on the upper surface of the submount and adjacent to the first light emitter and the second light emitter;
- and
- a wavelength conversion component disposed on each of the first light emitter, the second light emitter, and the light affecting material, the wavelength conversion component comprising a transparent substrate, a first phosphor zone supported by the substrate and registered with the first light emitter, and a second phosphor zone supported by the substrate and registered with the second light emitter, wherein the second phosphor zone comprises a phosphor that is compositionally different from a phosphor of the first phosphor zone.
A wavelength conversion component, comprising:
- a transparent substrate having an upper surface and a lower surface;
- a first spray-coated phosphor material supported by the lower surface;
- and
- a second spray-coated phosphor material supported by the lower surface, wherein the second spray-coated phosphor material comprises a phosphor that is compositionally different from a phosphor of the first spray-coated phosphor material;
- and wherein the first spray-coated phosphor material and the second spray-coated phosphor material are configured to alter a wavelength of a light emitted from a light source when the lower surface is positioned proximate to the light source.
