System for directing light includes a light source (10) and a generally tubular, hollow coupling device (12,14) with an interior reflective surface for receiving light from the source (10) and an inlet and transmitting it as a generally diverging light beam at a reduced angle through an outlet (20). A thermal-isolating region (16) has an inlet (22) proximate an outlet (24) of the coupling device and an outlet for passing light to an optical member (26). An arrangement for splitting the light from the outlet of the foregoing region comprises a plurality of light guides (30). Each light guide (30) includes an inlet end (26a,28a) for receiving light from the thermal-isolating region and an outlet end for directing light to a remote location (24,28). The inlet ends are substantially coplanar with each other and form a substantially solid shape (26a,28a). The coupling device (12,14) and thermal isolating region (16) are shaped so as to distribute a respective, substantial amount of light to each of the plurality of light guides. |
