Abstract
A light emitting diode (LED) optical system. Implementations disclosed in this document may include two or more LEDs coupled with a circuit board and two or more optics. The two or more optics may each include a first end and a second end where the second end opposes the first end and a first optical stage including the first end. A second optical stage may be included that includes the second end. The first optical stage may include a total internal reflector and the second optical stage may include an upper reflector portion located at the second end. The two or more optics may be coupled over the two or more LEDs at their first ends and the two or more optics may be coupled to each other along a portion of their first optical stages and at their second optical stages.
