Abstract
A light guide () including a transparent element is presented. The transparent element includes a first end () including a place for a light source, a second end () opposite the first end, an outer surface () between the first and second ends, and an interior channel () extending from the first end to the second end. The interior channel includes a first portion () beginning from the first end and a second portion () extending to the second end. The first portion is shaped to guide at least part of light falling to its wall into the transparent material and the outer surface provides total reflection for reflecting the light towards the second end. The second portion is shaped so that light passed through the first portion without falling to a wall of the first portion reaches the second end without falling to a wall of the second portion.
