Abstract
A light emitting diode (LED) optical system. Implementations may include an LED coupled with a printed circuit board and an optic. The optic may include a first end and a second end opposing the first end. The optic may also include a first optical stage including the first end and a second optical stage including the second end. The first optical stage may include a total internal reflector and a second optical stage includes an upper reflector located at the second end. The optic may be coupled over the LED at the first end. The second optical stage may be configured to emulate a point light source for an outer lens coupled over the LED optical system using light emitted from the LED.
