发明名称 High efficiency dual output light source
摘要 A centralized lighting system is provided having a high intensity light source which is disposed at approximately the first optical focal point of an ellipsoidally shaped reflector member. A mirror member, disposed in advance of a second optical focal point associated with the reflector member, receives light output from the light source and is constructed so as to divide the light output into at least first and second beam portions. The mirror member is further effective so as to separate the first and second beam portions by at least 90 degrees relative to one another. Corresponding at least first and second optical transmission members are receptive of the first and second beam portions and are effective for communicating the light output to locations remote from the light source. In one embodiment, the mirror member is V-shaped and is constructed of first and second mirror segments joined together so as to form an angle of less than about 85 degrees therebetween. The mirror member is effective for dividing the beam portions so that such beam portions are substantially equivalent to one another in terms of intensity, shape and color. The V-shaped mirror member is further effective for separating the first and second beam portions by approximately 180 degrees relative to one another.
