摘要： A solid-state lighting device for illuminating a predetermined area having a width and length includes a reflector having at least one cavity. At least one edge emitting solid-state light-emitting device is positioned relative to the cavity of the reflector. The cavity includes an inner curved surface terminating at an edge proximate the solid-state light-emitting device. The inner curved surface has a curvature such that a light intensity of the device has a sharp drop-off in intensity at a boundary of the width and a slowly attenuating light at a boundary of the length.
