Abstract (en)

[origin: WO0050940A1] A compact optical assembly includes a tight bend region (50) that effectively propagates light from a source (30) to an end use while maximizing beam lumens, improving color mixing, and minimizing complexity. A first nonimaging optical component (60) increases the angular distribution of light from the source (30) to an input end (60b) of the bend region (50) having a light fiber (64) with a first cross-sectional dimension. A second nonimaging optical component (62) receives light from the bend region (50) and decreases the angular distribution. A light conductor that interconnects the light source (30) to the first nonimaging optical component (60) has a cross-sectional dimension in the plane of the bend region (50) greater than that of the light fiber (64) and, likewise, a second conductor receiving light from the second nonimaging optical component (62) has a cross-sectional dimension in the plane of the bend region (50) greater than the light fiber (64).
