Should fiber optic cables have a skylight
Fiber optic cables bring natural daylight all the way into windowless spaces without skylights and other openings, using solar collectors. Fiber optics have enabled everything from light-transmitting concrete to see-through wood, but lately have found even more innovative applications for interior daylighting. Passing through a thin wooden wall or concrete block is one thing – but imagine natural light that could wind its way through. This focused sunlight is directed into a fiber optic strand, each individual strand is combined with other strands to create a fiber optic cable, 7 mm in diameter. Each of these cables can be up to 60 feet long. These cables can be routed. FIBER OPTIC CABLE DELIVERS DAYLIGHTThe Fiber Optic Skylight by HUVCO Daylighting Solutions comprises an exterior mounted panel containing 64 computer-controlled lenses that focus sunlight into optical fibers. The fibers transport the natural light up to 60 feet (18 m) to deliver it where not. IMAGINE A DEVICE THAT SITS ON the roof of a building and focuses sunlight into cables the size of electrical wire.
