Abstract
An LED optical assembly includes an optic having first and second light entry surfaces configured to cooperate respectively with a first light emission surface and an internal reflective surface to redirect substantially all light emitted from an LED into a direction substantially parallel with the optical axis. A polygonal periphery extends from the internal reflecting surface to a second light emission surface. Substantially all of the light emitted from the LED incident on the second light entry surface is incident on the internal reflecting surface. The first light entry surface and the second light entry surface cooperate to prevent the light emitted from the LED from contacting the polygonal periphery.
