Abstract
A lamp includes a substrate, a plurality of light-emitting devices located over the substrate, and a cap that is located over the light-emitting devices. The plurality of light-emitting devices include a first subset of light-emitting devices and a second subset of light-emitting devices. Each light-emitting device in the first subset is free of a phosphor coating. Each light-emitting device in the second subset includes a phosphor coating. The cap has both photo-conversion properties and light-scattering properties, and the cap is located over the first subset of the light-emitting devices but exposes the second subset of the light-emitting devices.
