Abstract
A semiconductor light-emitting device which provides optically undistorted light includes a semiconductor light-emitting element and at least one optical element. The light emitting-element and the optical element are held in a resin which is transparent to light emitted from the light-emitting element so that light emitted from the light-emitting element travels to the optical element along an optical path entirely within the resin, but the light exits a portion of the optical element located outside of the resin.
