Packaged wavelength converted light emitting device
Embodiments of the invention include a plurality of light emitting devices, each light emitting device having a top surface, a bottom surface opposite the top surface, and at least one side surface connecting the top surface and the bottom surface. A wavelength converting layer is disposed in direct contact with the top surface and one side surface of each of the plurality of light emitting devices to mechanically connect each of the plurality of light emitting devices together. The wavelength converting layer is made up of a wavelength converting material, an adhesive material, and a transparent material that has a thermal conductivity of at least 0.2 W/mK. The adhesive material and the transparent material have indices of refraction that vary less than ten percent.
