Abstract
An optical structure for controlling distribution of light generated by a light source is described. The optical structure includes a primary optics disposed relative to the light source and configured to reflect light generated by the light source towards a target region. The optical structure also includes a secondary optics disposed and aligned relative to the primary optics. The secondary optics is configured to at least partially block light generated by the light source from illuminating a region outside the target region.
