Abstract
A package includes a light emitting portion configured to emit light, a lens including a first lens surface and a second lens surface, a protective layer between the light emitting portion and the first lens surface and that shields the first lens surface from a surrounding environment, and an optical component that redirects light output from the second lens surface. The first lens surface is configured to receive the emitted light from the light emitting portion, the second lens surface is configured output light that has passed through the first lens surface, and the protective layer has a refractive index greater than 1.5.
