Patent Images
1. A lighting apparatus, comprising:
- a housinga substrate located in the housing;
at least one light source attached to the substrate, the at least one light source being configured to emit light having a first peak wavelength; and
a carrier layer attached to the housing;
wherein the carrier layer comprises first and second wavelength-converting materials configured to convert the light emitted from the at least one light source into a substantially white light having a first color point; and
wherein the carrier layer is substantially thermally isolated from the light source.

Abstract
A lighting apparatus having wavelength-converting materials formed in a carrier layer is disclosed. In one embodiment, the lighting apparatus has a light source attached to a substrate that is assembled in a housing. The light source is configured to emit a substantially narrow band light that is transformed into broad-spectrum white light by the wavelength-converting materials positioned on the carrier layer. The wavelength-converting materials and the carrier layer are distanced away from the light source, such that the carrier layer is thermally isolated from the light source.
