Abstract
A light emitting arrangement is suggested for generating directional projections of light with sharply defined beam profile. Light from a top-emitting solid state light source (), having reflective side-coating (), is pre-collimated via a beam-shaping optic (), before being propagated through a secondary collimating funnel (), capturing any light rays with still too great an escape angle. Chip-scale package dimensions may be achieved through the use of a thin-film side-coating and undersized phosphor layers. Substrate level process flow further allows for parallel processing of a plurality of devices.
