by alanod gmbh amp co kg which has a reflectivity of approximately 98 the first support wall 128 also defines at least two apertures that are all optically coupled to the first light transfer duct 130 a light receiving port 134 receives light waves w from a solar light concentrator 136 and a first light delivery port 138 receives a summation beam sb from the first light transfer duct 130 although only two light receiving ports 134 and a single light delivery port 138 are illustrated in fig3 more concentrators 136 and light receiving ports 134 are contemplated in other examples the term optically coupled refers to the arrangement of features that allows the transfer of light using various techniques known in the art of optics in general two features are optically coupled if light can be transferred between the two either directly or through the use of optic devices such as lenses and reflectors a first turning reflector 140 is disposed inside of the first light transfer duct 130 and is located proximate to each one of the one or more first light receiving ports 134 the first turning reflectors 140 are mounted to the first tubular member 124 rigidly or adjustably to allow for angular adjustments to the central longitudinal axis cl 1 the first turning reflectors 140 receive the solar light waves w through the light receiving ports 134 and direct the light waves w down the first.
