Abstract: The illumination optic is a collimator lens having a solid monolithic structure that includes spaced-apart and longitudinally-extending side lobed segments laterally disposed around a central core section. Each lobed segment has a TIR inner peripheral surface extending from a rear side towards a front side of the collimator lens and has a light exit surface generally facing the front side. Also disclosed is an illumination device including the collimator lens and a diffusion lens that is coaxially positioned next to its front side to redirect light coming out of the light exit surfaces. The diffusion lens has spaced-apart outlying optical regions disposed around a central optical axis, at least one for each light exit surface, to be selectively positioned in or out of alignment with a corresponding one of the light exit surfaces depending on a relative angular position between the collimator lens and the diffusion lens.
