Abstract
The invention relates to an illumination system converting light beams into wide-angle light transmissions. It includes i) a cylindrical member having a cone-shaped depression in a distal end; and ii) a semi-circular member having an inner radial surface adjacent to a sidewall of the cylindrical member; and angled upper and lower annular surfaces extending from the cylindrical member and meeting at an outer radial edge. A light beam entering the proximal end of the cylindrical member strikes a first edge of the cone-shaped depression and is reflected out as a first light transmission; or it strikes a second edge of the cone-shaped depression, is reflected against the upper and lower annular surfaces, and exits the cylindrical member as a second light transmission parallel to the first diffused light transmission. At least one light path passes through a diffuser on the cylindrical member.
