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.
