Abstract
Abstract A light pipe including a light diverting section, in which light flowing through the light pipe in a longitudinal direction is diverted at least generally radially out from the light pipe or, alternatively, the light diverting section can be used as a receiver (rather than a transmitter) to collect light rays from light emanating around the device and divert them for passage down through the light pipe. An automotive application of the former, transmitter mode is serving as a visula indicator from a remote location in which the surface end of the light pipe is not clearly visible, such as for example on a "black box" located under a vehicle seat. An automotive application of the latter, receiver mode is as a light collector to receive or accept infrared rays from any compass position and from a range of vertical positions and direct them to a receptor, as part of an infrared personal entry system into the vehicle. The light diverting section includes a centrally located reflective surface on its side distal to the light pipe section which is conical (FIGS. 4 and 5) or concavely curved (FIGS. 1 and 2), the latter causing vertical as well as radial dispersion.
