Abstract:
An apparatus for efficiently deflecting light from an optical fiber around a bend, comprising:a non-imaging optical waveguide, said waveguide being bound by and having a first port and a second port, said non-imaging waveguide comprising structure means for efficiently directing all the light entering through said first port around said bend and to said second port, said first port being nonparallel and angled with respect to said second port, and said first port and said second port bounding said non-imaging waveguide to form said bend; said first port receiving light having divergence angles of less than 90 degrees as measured relative the central axis of said optical fiber, said central axis of said optical fiber being perpendicular to said first port; said second port emitting light having divergence angles as large as 90 degrees relative to the central axis of said second port, said central axis of said second port being perpendicular to said second port.
