    Abstract: Reflector assemblies and lighting devices incorporating such reflector assemblies are disclosed and described. The reflector assembly includes a reflector body defining an interior reflective surface that in some embodiments has a shape akin to a compound elliptic paraboloid. One or more LEDs can be maintained relative to the reflector body such that an entirety of a light cone emitted by the LED reflects from the interior reflective surface out to the world as a collimated beam. Lighting devices enable light rays to travel with a greater solid angle from LEDs than traditional in-plane optics. Light from a directional point source with a mounting position that is embedded in reflector body oriented to face an opposing curved mirror wall surface so light rays that are diverging prior to reflecting off the interior reflective surfaced are merged together after the reflective bounce to travel in parallel as a collimated beam.

By positioning the lighting device (100) at the intersection of two surfaces (S1, S2) such as can be found in a step, or at a corner of a wall, or at a corner inside a closet, or on the intersection area of ceilings, the two intersecting surfaces can be illuminated at the same time with comfortable light distribution, using a simple structure that can be easily installed.
