LIGHTING ASSEMBLY

WIPO Patent Application WO/2012/158444

A3

A lighting assembly includes a light guide and a light source. The light guide has opposed major surfaces and side surfaces extending between the major surfaces. The light source is at an apex region between two side surfaces and is configured to input light to the light guide. The side surfaces comprise a stepped reflective side surface extending from the apex region and comprising a first reflective step and a second reflective step, and an output side surface extending from the apex region and comprising a first output region and a second output region. The first reflective step is configured to reflect a first portion of input light through the first output region. The second step is configured to reflect a second portion of input light through the second output region. The second output region comprises segments oriented nominally normal to the reflected second portion of the light incident thereon.
