The Akemi Sun-Tech directs real sunlight into the interior via optical fabrics.  The efficiency of this technology is immensely high and thus creates a large energy saving of at least 50 %.

Fresnel lenses collect the light on a suntracker and the spliced optical fabrics bring the light into the desired room by means of total reflection. The Akemi light object is docked onto this so that it is fed with sunlight.
