Abstract
An optical system may comprise an emitter assembly and an optical structure that are configured to be used with a lighting device for providing a narrow beam angle for the lighting device. The emitter assembly may comprise an array of emitters configured to emit light. The optical structure may comprise a body having a light-entry portion, a light-exit portion, and side wall extending between the light-entry portion and the light-exit portion. The side wall of the optical structure may define a total internal reflection (TIR) surface. The light-exit portion may comprise a front surface and an octagon-shaped well formed into the front surface. The octagon-shaped well may have a center surface surrounded by a beveled portion configured to refract light that is reflected off of the TIR surface towards a central axis of the optical system, such that light rays that are transmitted from the light-exit portion are substantially collimated.
