1. A semiconductor light emitting device comprising:
- a substrate having a face;
a cavity on said face;
first and second semiconductor light emitting elements in the cavity;
a first phosphor layer that is spaced apart from the first semiconductor light emitting element and is arranged such that light that is emitted by the first semiconductor light emitting element impinges on the first phosphor layer; and
a second phosphor layer that is spaced apart from the second semiconductor light emitting element and is arranged such that light that is emitted by the second semiconductor light emitting element impinges on the second phosphor layer;
wherein the first semiconductor light emitting element and the first phosphor layer are configured to emit light of a first color and the second semiconductor light emitting element and the second phosphor layer are configured to emit light of a second color that is different from the first color.
