Abstract

Optical systems are disclosed herein for re-distributing light generated by a light source. For example, in one exemplary embodiment of the invention, the optic includes an optical body disposed about an optical axis. The optical body includes a proximal end and a distal end and a peripheral surface extending at least partially therebetween. An input surface disposed at the optical body's proximal end receives light from a light source. An optical redirecting element that is disposed at the optical body's distal end includes an output surface and a redirecting surface. The redirecting surface is configured such that substantially all light received from the peripheral surface undergoes total internal reflection and is thereby redirected out of the optical body at least partially through the output surface, e.g., perpendicular to the optical axis and/or in a proximal direction.
