1. A lighting apparatus, comprising:
- a housing having a side surface defining an opening;
a substrate located within the opening of 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, wherein at least a portion of the emitted light can be reflected by the side surface;
a carrier layer located within the opening and positioned directly on the side surface of the housing, wherein the carrier layer has opposing side surfaces and is substantially thermally isolated from the light source; and
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;
wherein the first wavelength-converting materials are arranged on one of the opposing surfaces of the carrier layer such that a substantial portion of light emitted from the light source passes through only the first wavelength-converting materials, wherein the second wavelength-converting materials are arranged on an other one of the opposing surfaces of the carrier layer such that a substantial portion of light emitted from the light source passes through only the second wavelength-converting materials, and wherein at least a portion of the emitted light can be reflected by the side surface toward the first and second wavelength-converting materials.

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.
