Abstract: Solid-state lighting devices, and more particularly, asymmetric light-emitting diode (LED) optic for asymmetric luminaire applications for LED packages are disclosed. The asymmetric LED optic can be a lens or other type of refractive element that has one or more indentations or other features that cause internal reflection such that some portion of the light exits a refractive element in a first direction and a portion may instead be refracted to exit the lens elsewhere. The LED package comprising these refractive elements can thus provide asymmetric illumination to a lighting area. One exemplary application could be street lighting, where light can be preferentially directed toward a roadway and away from houses or other areas away from the road.
