摘要： A light guide includes a body having an elongate shape and a plurality of light-reflecting faces and light-emitting faces extending along the body. The light-reflecting faces extend in a stepped fashion along the body in the direction of a longitudinal axis of the light guide and are configured to reflect light rays by the principle of total internal reflection. Each light-emitting face is disposed along the body opposite a corresponding light-reflecting face. Each light-emitting face is configured to emit light reflected by the corresponding light-reflecting face. The light-emitting faces are also disposed on the body in a stepped fashion. Steps of the light-emitting faces correspond to steps of the light-reflecting faces. In another aspect, the light-reflecting faces are separated by stepped-down faces. The stepped-down faces are oriented at a stepped-down angle in the range of about 1 and 10 degrees with respect to the longitudinal axis of the light guide.

摘要： An illuminating device has a light pipe that is elongate in shape and has a light-emitting face running in the direction of a longitudinal axis. A light-reflecting face is disposed opposite the light-emitting face, and the light-reflecting face has a plurality of prismatic cuts. Each prismatic cut includes a front face oriented at an angle B from a normal axis, the normal axis being 90 degrees from the longitudinal axis of the light pipe. The angle B is in the range of about 5 degrees to about 45 degrees and is such that it allows light to refract through at least one prismatic cut and then be internally reflected.
