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