    Abstract: A light guide (201) including a transparent element is presented. The transparent element includes an optical diverter section (204) including one or more reflective surfaces (205) forming walls of a notch (206) extending into the diverter section, where the reflective surfaces provide total reflections for directing light into directions lateral with respect to an arrival direction of the light. The transparent element includes an optical channel section (208) for receiving the light from a light source and for directing the light to the optical diverter section. The optical channel section includes a side surface (209) shaped to provide total reflections for directing light to the optical diverter section. The optical channel section makes it possible to place the light source a distance apart from the optical diverter section and also to prevent or at least to reduce direct propagation of light from the light source to the lateral directions.

    Abstract: A light guide (201) including a transparent element is presented. The transparent element includes a first end (203) including a place for a light source, a second end (204) opposite the first end, an outer surface (205) between the first and second ends, and an interior channel (206) extending from the first end to the second end. The interior channel includes a first portion (207) beginning from the first end and a second portion (208) 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.

    Abstract: An optical device includes a reflector-section that includes a light-ingress surface for receiving light from a light source, a reflector surface for reflecting the light based on total internal reflection, and a light-egress surface through which the reflected light exits the optical device. When the light source is at a predetermined position with respect to the optical device, an angle of incidence (θi) of the light at the light-egress surface is a polarization angle at which a p-polarized component of the light is transmitted through the light-egress surface without being reflected by the light-egress surface. Thus, unwanted reflections at the light-egress surface can be reduced and thereby unwanted scattering of light is reduced while having good transmitting efficacy.
