Abstract

In some embodiments of the invention, a device includes a semiconductor light emitting device having a first light extraction surface, a wavelength converting element, and a second light extraction surface. A majority of light extracted from the semiconductor light emitting device is extracted from the first light extraction surface. The first light extraction surface has a first area. The second light extraction surface is disposed over the first light extraction surface and has a second area. The first area is larger than the second area.
